GENERAL CRITICAL AREAS REPORT REQUIREMENTS Critical Areas Reports identify, classify and delineate any areas on or adjacent to the subject property that may qualify as critical areas. They also assess these areas and identify any potential impacts resulting from your specific development proposal. If a specific development proposal results in an alteration to a critical area the critical areas report will also contain a mitigation plan. You have the option of completing the portion of the study that classifies and delineates the critical areas and waiting until you have a specific development proposal to complete the study. You may also choose submit the entire study with your specific development application. Please review the minimum report requirements for all types of Critical Areas which are listed in ECDC 23.40.090.D. There are additional report requirements for different types of critical areas (see below). Note that it is important for the report to be prepared by a qualified professional as defined in the ordinance. There are options on how to complete a critical areas study and an approved list of consultants that you may choose from. You may contact the Planning Division for more information. General Mitigation Requirements for all Critical Areas are discussed in ECDC 23.40.110 through 23.40.140. REPORT REQUIREMENTS — WETLANDS The site investigation has shown that the site may contain or be adjacent to a wetland. Wetlands are areas inundated or saturated by ground or surface water that support, under normal circumstances, vegetation adapted for life in saturated soil. • Wetlands are generally rated according to their size, condition, function, and vegetation types into four (4) different categories described in ECDC 23.50.010 and by use of the "City of Edmonds Wetland Field Data Form" by the critical areas consultant. • Buffer widths for wetlands vary depending on the category of the wetland as listed in ECDC 23.50.040.F. • In addition to the general requirements for Critical Areas reports referenced above, there are specific Critical Areas report requirements for wetlands that are provided in ECDC 23.50.030. • DEVELOPMENT PROPALS ASSOCIATED WITH WETLANDS Development proposals that encroach into wetlands or their buffers or building setbacks may be allowed through the approval of certain processes. • The width of a wetland buffer may be reduced through buffer enhancement if the criteria described in ECDC 23.50.040.F.3 can be met. The maximum amount that a buffer can be reduced through buffer enhancement is 50%. • A buffer may also be modified through a process called buffer averaging. The criteria applied to buffer averaging are listed in ECDC 23.50.040.F.4. The maximum amount that the buffer width can be reduced at any single location through buffer averaging is 50%. Development proposals that proposed encroachments into buffers beyond what is allowed through the above methods require a Critical Areas Variance, or a Reasonable Use Exception. If you think that you have a proposal that may require one of these processes, please contact a Planner for more information. Any time a development proposal requires an alteration to a wetland, a mitigation plan is required as part of the Critical Areas report. In addition to the General Mitigation requirements referenced above, mitigation requirements specific to wetlands are provided in ECDC 23.50.050. NOTE: There are specific performance standards for the subdivision of lands in wetlands and wetland buffers. These are listed in ECDC 23.50.060. STUDY REQUIREMENT — EROSION HAZARD AREA It appears that this property contains or is adjacent to an Erosion Hazard Area. • Erosion Hazard areas include Alderwood and Everett series soils on slopes of 15 percent or greater. among others. • Landslide Hazard Areas are further defined in ECDC 23.80.020.A. • In addition to the general requirements for Critical Areas reports referenced above, specific Critical Area report requirements for Erosion Hazard Areas (which are one of the Geologically Hazardous Areas) are provided in ECDC 23.80.050. • Note that Stable Erosion Hazard Areas may have limited report requirements at the director's discretion. At a minimum an erosion and sediment control plan prepared in compliance with the requirements in ECDC Chapter 18.30 shall be required. DEVELOPMENT PROPOSALS ASSOCIATED WITH EROSION HAZARD AREAS Development is restricted within an Erosion Hazard Area. • Projects that will intrude into these areas will require a report by a licensed Geotechnical Engineer or other qualified professional. • Development standards are given in ECDC 23.80.060 and 23.80.070. STUDY REQUIREMENT — LANDSLIDE HAZARD AREA It appears that this property contains or is adjacent to a Landslide Hazard Area. • A Landslide Hazard Area is any area with a slope of forty percent (40%) or steeper and with a vertical relief of ten (10) or more feet (except areas composed of consolidated bedrock). • Landslide Hazard Areas are further defined and illustrated in ECDC 23.80.020.B. • In addition to the general requirements for Critical Areas reports referenced above, specific Critical Area report requirements for Landslide Hazard Areas are provided in ECDC 23.80.050. 2 T PROPOSALS ASSOCIATED WITH L ►ZARD AREA; Development is restricted within a Landslide Hazard Area and its buffer. • Projects that will intrude into these areas will require a report by a licensed Geotechnical Engineer. • The criteria that are applied depend on the amount that the buffer is reduced. • The buffer can be reduced to a minimum of ten (10) feet (with an additional 15' building setback per ECDC 23.40.280) if a report is prepared that meets the standards listed in ECDC 23.80.050. The alteration must also meet the requirements listed ECDC 23.80.060. • In addition, proposals to reduce the buffer to -less than ten (10) feet must comply with the design standards listed in ECDC 23.80.070.A.3. STUDY REQUIREMENT — FISH AND WILDLIFE HABITAT CONSERVATION AREAS Since the site is within a mapped fish and wildlife habitat conservation area, the City would like to preserve as much of the native vegetation as possible. DEVELOPMENT PROPOSALS ON A SITE WITH FISH AND WILDLIFE HABITAT CONSERVATION AREAS The applicant must submit a clearing/tree cutting plan with any development permit. Tree cutting and clearing of native vegetation shall be limited to the footprint of development. ALLOWED ACTIVITIES Certain activities are allowed in or near critical area buffers as specified in ECDC 23.40.20. If you have any questions about whether your proposed development qualifies as an allowed activity, please contact a Planner for more information. EXEMPT DEVELOPMENT PROPOSALS Certain development proposals may be exempt. from Critical Areas Requirements (ECDC 23.40.230). If you think that a specific development proposal may be exempt, contact a Planner for more information.

EXECUTIVE SUMMARY The proposed project is located at 16007 — 73`d Place West in the City of Edmonds, Washington. More generally, the site is located in Section 5, Township 27 North, and Range 4 East of the Willamette Meridian in Snohomish County, Washington. Please refer to the Vicinity Map attached in the next section. The approximate 0.14-acre site is currently vacant land consisting primarily of residential lawn. The entire site in located inside a geologically hazardous area. The main hazard is landslides and the resulting landslide debris generally covering'the site. See Geotechnical Report issued March 31, 2008 by Terra Associates, Inc. authored by Charles R. Lie, L.E.G. and stamped by the company principal Theodore J. Scheppler, P.E. The site contains Alderwood-Urban Land Complex type soils. Please refer to the soil map and descriptions attached later in the geotechnical report. Other Geotechnical Reports have been listed in the above report. The planned development for the site includes the construction of 1 new single-family residence, which essentially covers most of the lot. No roadwork is proposed along the frontage except the addition of a driveway to connect the garage to the road. Since this is a landslide hazard area, with groundwater seeping from the hillside above the residence, we are proposing No storm water detention system. All of the past studies from a number of engineering companies have all recommended immediate removal of all storm water and groundwater from the area. The purpose of a detention system is to contain storm water and release it at the pre -developed rate, mimicking the natural runoff before the development. Installing a pipe detention system would negate any benefits derived from this system. Any chance of the detained runoff infiltrating back into the soils may have a grossly negative, long- term effect, to the area. Sewer service is provided from an existing sanitary side sewer and cleanout located near the northwest corner of the site. Excavation is required to provide the side service tap to the new residence. Water service will be provided by a new side service tap and a meter located just north of the new 30' driveway. At this time it is unknown if a NFPA 13-D fire suppression system will be installed.

The entire site in located inside a geologically hazardous area. The main hazard is landslides and the resulting landslide debris generally covering the site. Due to the recent approval of a clearing and grading permit, through the City of Edmonds, the site has been roughly cleared and graded for the new single-family building permit. The entire site consists of stabilized soils overlaid with jute matting and hydroseed. Per site visit on January 91h, 2010, new grass growth has began on -site with no other significant vegetation. 3. OFFSITE ANALYSIS A site reconnaissance was done by Barry R. Constant, P.E. of Western Engineers Inc. on October 19, 2007 to verify the downstream flow paths. The weather was rainy with a temperature around 55 degrees. The approximate 0.14-acre site is currently vacant land. The entire site in located inside a geologically hazardous area. The main hazard is landslides and the resulting landslide debris generally covering the site. The site contains Alderwood-Urban Land Complex type soils. Please refer to the soil map and descriptions attached later in this report. A: Upstream Analysis Upstream flows into the site primarily consist of steady hillside `seeps' and runoff from upslope from the neighboring property to the east. These flows are considered major contribution to this landslide hazardous area and cannot be ignored. B: Downstream Analysis Please refer to the Downstream Analysis Map attached in the next page for a detailed description of the downstream drainage course. From the surrounding topography, and topographic aerial maps, it appears that the majority of runoff from the site travels west and into the existing underground conveyance system located along the east side of the private road (Lorian Woods drainage conveyance system). As the runoff enters into the existing conveyance system, the flow travels north and eventually turns west and enters into the underground detention system installed for the Plat. From the detention system, the flow outlets to the north and enters into the main drainage system on the north side of N. Meadowdale Road (city drainage system). The drainage system on the north side of N. Meadowdale Road conveys the majority of the runoff from the area, to the west where it eventually enters into Puget Sound approximately 200 yards west of the site. No visible offsite drainage problems were observed at the time of field inspection. Refer to the following pages for Downstream Analysis Map, Aerial Basin Map and USGS Map.

DRAINAGE PROPOSAL The planned storm water development for upstream flows includes a dedicated drainage conveyance system for the hillside seeps, upstream flows and extensive drainage around the new catchment / retaining wall. On -site drainage, for the new patio, residence and driveway will consist of perimeter roof and footing drains. The roof and footing drains are to consist of separate systems which will connect to the recently installed storm conveyance system located along the frontage of the site. The hillside seeps have been located in the field by Western Engineers, Inc. surveyors. As mentioned, in almost all of the previous reports, collecting this drainage and other upstream flows and keeping it from infiltrating into the landslide debris is paramount to the safety of the residence and future stability of the hillside. Through recent construction, a number of aluminum (or similar) trays fabricated, have been installed that will collect the water from the seep area and convey the drainage to the cities storm system and the storm system constructed for the Lorian Woods Plat. Upstream flows, that travel west along the south side of the property, have been bypassed around the site and connect to the cities storm conveyance system located in the center of the private road used to access the site. From there, the cities drainage system travels north, under the existing private road, where it eventually intersects with the existing city drainage system located at the north side of the intersection of the private road and North Meadowdale Road. All other upstream flows to the east of the site travel west, along the northern boundary line of the site, and connect to the private storm system for the Lorian Woods Plat. As the flow connects in to the private system for the Lorian Woods Plat, the flow travels west and then south into an existing detention pipe installed for the original plat (located on the property at the southwest side of the intersection of the private road and North Meadowdale Road). From the existing detention pipe, the flow travels north across North Meadowdale Road, and into the cities storm conveyance system. Refer to the updated civil drawings that represent the recently installed storm system along the north and south perimeters of the site. The catchment / retaining wall, located along the eastern boundary line of the site, is a geotechnical recommendation to protect the residence from any possible landslide debris from impacting the structure. This wall was designed by Reed & Associates based on a boring advanced onsite previously this year. The catchment wall will extend vertically 3-feet (minimum) above the existing grade where the wall is located. Extensive underground drainage, on the upper side of the wall, is planned to be constructed with the proposed building permit which will bypass any upstream flows entering the site. The upper wall drainage will provide geotechnical fabric against to upper wall or install washed drain rock as an alternative for ground water and rainfall runoff to enter the footing drain. See detail on sheet 5 of the revised civil plans. E: / 2006 / 06792A / Engineering / Targeted Drainage Report.doc 4. DRAINAGE PROPOSAL (continued) The new storm piping slopes are dependant on the final elevations of the upper portion of the soils above the wall. We recommend that the wall drain system on the uphill side has a clean -out located at the highest soil elevation on the wall (near the middle), and the perforated pipe sloped down gradient to each end of the wall. The pipe shall be continuous in nature from the clean out at the north end of the wall to the south end. The pipe, just at the south end of the wall, should become solid pipe and tight lined directly into the drainage conveyance system located along the southern boundary line of the site. See Geotech Report for further recommendations. As the catchment wall is integrated into the house foundation through the reinforced concrete patio surface itself (approx 12-16-inches thickness), the under patio drainage system must be installed prior to concrete placement in the patio area. See design drawings for specifics. We anticipate that the house foundation will be installed first, then the catchment wall and finally the patio surface. The contractor must also ensure that all patio and footing drains are installed prior to the concrete placement on the patio. Patio surface is sloped towards the drains at a 2 percent maximum. The high point in the patio drainage system is designed around the rooftop downspouts, which tie into the under patio drainage system. From the high point, near the northern end of the patio, the drainage flows to the south and into the storm conveyance system located along the southern boundary line of the site. Since this system can only be installed once, all care must to taken to ensure that the pipes and rooftop connections are installed correctly and of top quality materials. The residence will have two dedicated drainage systems that include rooftop runoff control, footing drains and foundation wall geotechnical drainage composite. All rooftop downspouts will be directed into an underground, solid, tight lined collection system separate from the footing drains (see sheet 5 in the drainage plans for details). A clean out shall be installed at the highest elevation point and at any other location the contractor deems necessary (more clean outs is better than less). The drainage plan shows the system, general in nature, as a pipe system directed to flow down gradient into a catch basin located on the west side of the residence at the private road. This is an existing catch basin at the roadway. We are relying on the expertise of the contractor to ensure that the system will be sloped to drain. This system shall be completely separate from the footing drains except at the connection catch basin, both pipes may enter the catch basin so long as the outlet elevation is below all house drainage elevations. E: / 2006 / 06792A / Engineering / Targeted Drainage Report.doc 4. DRAINAGE PROPOSAL (continued) The footing drains are the typical system (see detail on sheet 5 of the drainage plans or figure 3 in the geotechnical report). We also specify that a geotechnical composite fabric shall be installed on those portions of the outer foundation walls. See geotechnical report, Figure 3, for installation recommendations. As an alternative, the foundation wall can also have approximately 6-inches of washed drain rock placed outside the composite fabric, around the spread footing and around the perforated PVC footing drain pipeline. This pipe shall be located at the lower portions of the spread footings. In order to match the drainage calculations prided from the Plat of Lorian Woods, the roof drains for the new house will tie into the Lorian Woods drainage system near the north side of the new driveway pad. This drainage system will also convey runoff from the new driveway pad area. The Lorian Woods drainge system will then convey the runoff north and west into the existing detention pipe installed for the Plat of Lorian Woods. Total new runoff from the site directed to the Lorian Woods detention system total approximately 4,048 sf. This is roughly equal to the designed impervious surface area for the existing detention pipe which totals approximately 3,997 sf. (includes 2,700 sf, for new house, 315 sf. for new driveway and 982 sf. of street area which was never installed). Refer to the drainage calculations section for additional information. Due to the site proposing more impervious area that what was additionally designed for, the new impervious areas from the east patio area, catchment wall and south steps will bypass the Lorian Woods drainage system and enter into the City of Edmonds drainage system (located along the south side of the property). The total area expected to by pass the Lorian Woods detention system is estimated at 763 sf. Refer to the drainage calculations section for additional information. . Following the above recommendations are necessary to ensure that the residence and the surrounding area can remain as `dry' as possible. This will reduce future landslide hazards and possible structural problems with differential settlement of the residence. E: / 2006 / 06792A / Engineering / Targeted Drainage Report.doc 5. DRAINAGE CALCULATIONS Total Area of the Site = 5,897 sf. (0.135 Acres) As per the Soil Survey of the Snohomish County Area, the development area on site is primarily Alderwood gravelly sandy loam, which corresponds -to a Type C soil. For calculation purposes, a Type "C" soil was used. EXISTING SITE: Impervious area: Entire site consist of residential landscaping (grass). Pervious Area: Total - Impervious => 0.135 Ac. — 0.000 Ac. = 0.135 Ac. DEVELOPED SITE: Impervious area: New SFR (roof area) = 3,337 sf. Driveways and Front Steps = 711 sf. Concrete Patio Area = 588 sf. Catchment Wall = Ill sf. South Perimeter Steps = 63 sf. Total = 4,811 sf. (0.110 Ac.) Pervious Area: Total - Impervious => 0.135 Ac. — 0.110 Ac. = 0.025 Ac. *Rainfall 2- Year = 1.50 in.: 10- Year = 2.00 in.: 100- Year = 3.00 in. E: / 2006 / 06792A / Engineering / Targeted Drainage Report.doc 0 5. DRAINAGE CALCULATIONS (continued) Existing Plat Detention System Design Check: Refer to the attachment section in this report for the original drainage report for the Lorian Woods development. Note that in the drainage calculations section, the proposed impervious areas for lots 1 and 2 of the plat have been somewhat combined. It has been assumed that the site (lot 2) has been provided with 2,700 sf. of roof area and 315 sf. of driveway area (1/2 of total). 3,420 sf. of impervious area has been listed for street area. Note that the estimated "as - built" area of the existing private road, located along the frontage of lots 1 and 2, has been calculated at 2,438 sf. This is approximately 982 sf. less that originally calculated. Adding the excess street area not installed by the Plat of Lorian Woods, with the estimated house and driveway areas from the original calculations, the allowable impervious area designed to drain to the existing detention system totals 3,997 sf. The proposed amount of impervious surfaces proposed to enter into the Lorian Woods storm system has been estimate at 4,048 sf. (3,337 sf. of new house and 711 sf. of new driveway area). Though the proposed impervious area is slightly larger than the original impervious area calculated for in the existing detention pipe, the added 51 sf. of impervious area will have little to no effect on the allowable flows to enter into the pipe. Due to the proposed installation of a new patio, catchment wall and south step area, the runoff from these new impervious areas will bypass the Lorian Woods detention system and enter into the cities drainage system (located along the south boundary line of the site). The estimate area of these surfaces totals 763 sf. (588 sf. patio area, 112 sf. of catchment wall and 63 sf. of south perimeter steps). Note that the additional runoff added to the cities drainage system from these impervious areas will have little to no effect on the total runoff the existing city drainage system already contains.

OWNER: Robert and JoAnn Anderson 7370 North Meadowdale Road Edmonds, Washington 98020 INTRODUCTION: The project site is located south of North Meadowdale Road and east of the 74th Place West right-of-way in the Meadowdale area of Edmonds; Washington. The Anderson property includes Lots 54, 55 and 56 of the Plat of Meadowdale Beach and part of Lot 57. In plan it measures about 350 feet by 650 feet and includes approximately 5.3 acres. The Anderson residence is located on Lot 55 in the west center of the site. The eastern third of the property is a slope that gradually steepens toward the east. The upper slope climbs steeply to a bluff with its crest near Elev 250 to 300 off the site to the east. The central area of the property is a bench about 100 to 120 feet wide covered with grass, ivy and scattered trees. Grades on the bench vary from about Elev 120 in the north to Elev 150 in the south. The Anderson residence and a shed to the south are located on this bench. Several firs up to 47 inches in diameter and other large trees, straight-trunked and vertical, are located just south of the house. To the west the bench slopes down to the .74th Place West right-of-way. The grade change from the bench to the west property line ranges from ten feet at the north to about 50 feet at the south. Typical slope inclinations are in the range of 20 to 25 degrees with local areas as steep as 45 degrees. • The project provides for creation of nine additional building lots, single family residences. The 5.28 acre site presently has only the single residential home of the owners. Although currently zoned RS-20, actual density at completion will be 1.9 dwelling units per acre (gross area). Site planning further calls for approximately 148,000 SF (3.40 acres) of common open space. Specific location for building sites is based on topographic constraints, maintaining desired vegetation, privacy and view. EXISTING SITE DRAINAGE: In 1984, the City of Edmonds constructed under L.I.D. 210, certain improvements on the Anderson property, Interceptor Drains 1A and 1B. Refer to construction drawing sheet 9 of 30 dated April 1983 by Reid, Middleton & Associates, Inc. These interceptor drains were part of an area -wide drainage construction project to serve the North Meadowdale area. In addition to the collection systems, numerous subsurface interceptor facilities were provided. GEOTECHNICAL CONSIDERATIONS: An on -site geotechnical study was conducted by Terra Associates, Inc. summarized in their report dated June 6, 1989, and transmitted to the City of Edmonds Planning Department as part of this project's preliminary submittal and review process. Recommendations from that report have been included in the design criteria and basis for street, utility and site improvements. With respect to site drainage, the "Terra" report recommends extending the storm sewers to the end of the new roadway. This will provide an opportunity to install additional drainage at the toe of the east slopes and provide a place where lot owners can discharge their foundation drains and roof gutters. The storm sewers will be tightlined. The new storm drains will flow northerly and westerly to a detention system. From the detention system the storm water system connects to the existing storm drainage system on the north side of North Meadowdale Road. To pick up ground water seepage intercepted by the trench, drain rock bedding and perforated drain pipe will be installed in the excavations, as was done with the LID 210 storm sewers. The trench will be lined with filter cloth and backfilled with pea gravel, except within two feet of the surface. DESIGN PARAMETERS: Lots 3, 7, 8 and 10 have storm drain extensions that provide for all hard surface runoff interception. Surface runoff from the common area north and east of Lot 1 will flow northerly to the new gutter along the south side of North Meadowdale Road, then westerly into a catchbasin and the detention system for the North Basin. The area south of Lot 7 as well as the area west of the new access road and between Lots 3 and 10 will not be disturbed. As such, storm water flows will be allowed to exit the site undetained. The Q allowable leaving the site will be reduced accordingly. For purposes of system design, the major drainage basins established by Reid, Middleton and Associates for LID 210 were further detailed into the sub -basins appropriate for this project. These two were designated as the "North and South sub -basins." Calculations were made of expected improved surfaces at buildout and runoff therefrom determined. • The improved surface calculations are based on the approved PRD, which shows expected improvements, i.e., building footprints, driveways, roads, etc. Refer to the attached calculations for detail. In summary, detention requirements for the North Sub -Basin called for a closed -pipe system volume of 7-23 cubic feet, while the South Sub -Basin volume was found to be-IA-3-cubic feet. ��; ' :A SUMMARY OF CALCULATIONS: NORTH SOUTH BASIN BASIN Off -site -Existing - 10 yr.

Finnigan, III 604 Front Street Celebration, Florida 34747 Dear Mr. Finnigan.: In response to a recent localized slide, City officials conducted a site inspection on September 16, 2003 and observed slide damage to have occurred all on private property west of Sequoia Ridge Lot 4, at or near Tract A and Lot 2 property of the plat of Lorian Woods in Edmonds, Washington. Accompanying City officials was a representative of Landau Associates, the City's professional geotechnical consultant. Landau Associates conducted a site reconnaissance and subsequently prepared a report (copy enclosed) that describes the observed slide. Note, the report suggests that there is a low probability of immediate risk from the slide damage particularly because the downslope private properties are currently undeveloped. The report recommends that property owners in the vicinity of the landslide be alerted to the condition of the slope. The purpose of this letter and the attached copy of the Landau Associates report is to notify you and other private property owners in the area, of the current situation as we know it, so that you may take whatever action you deem appropriate. During the course of the site reconnaissance, the investigation also discovered ground cracking at or near, the top of the ridge line of Lot 3 Sequoia Ridge. The ground cracks observed in this area are estimated to lie above your lot at Lorian Woods Lot 5, a currently undeveloped lot. The significance of this ground cracking was not thoroughly investigated by the City's geotechnical consultant. However, the presence of ground cracking suggests an unstable slope condition that could have a relatively high risk of landsliding sometime in the future, particularly during wet weather. Since you may be unaware of these conditions, the City recommends that you have your professional Geotechnical Engineer make a site inspection for an independent assessment of your property to provide recommendations about the possible future impacts of landsliding, preventative measures to property your property and any possible site restoration that may be adviseable for you to undertake to protect your property. Geotechnical reports and assessments for properties within this area are on file at my office and area available for review. • Incorporated August 11, 1890 ° Mr. Finnigan Page Two September 25, 2003 If your geotechnical engineer requires restoration or slope mitigation/improvements an approved permit from the City is required since all work must comply to City Ordinance #2661 which regulates the Meadowdale Earth Subsidence Landslide Hazard Area.

Don Fiene and Ms. Jeannine Graf RE: LANDSL1-0 )FVA1..UA"r10N IA')(EADOWDALE AREA - LORL4N WOOUS/SEQUOIA RIDGE PLATS EDMONDS, WASHINcroN Dear Mr. Fiene and Ms. Graf: This letter sununarizes our observations and recommendations related to a landslide that occurred on the steep slope, east of 73'd Place West, in the northeastern part of the Lorian Woods plat, extending upslope to the western edge of the Sequoia Ridge Plat. At the request of the City of Edmonds (City), Deborah Ladd of Landau Associates visited the site on September 16, 2003 along with City of Edmonds personnel Dave Gebert, Don Fiene, Jeannine Graf, Ann Bullis, Noel Miller, and Jim Kammerer. The purpose of our visit was to assess site conditions and identify any imminent hazard to City -owned facilities and the general public from the observed slide. As part of our visit, we also observed surface conditions on the ridge near the top of the slide. Our services were provided under Task Order No. 22 of our on -call Geotecluiical Engineering Services Agreement with the City. BACKGROUND AND OBSERVATIONS The landslide is located in the northeast part of the Lorian Woods plat, east of Lorian Woods Lot 2 and west of Lot 4 in the Sequoia Ridge plat. The landslide lies north of the Ciry's interceptor drainage system "IA" and immediately north of catch basins CB #6 and CB #3 in this system. The landslide extends west to near (or onto) Lot 2 (16007 73rd Place West) in the Lorian Woods plat. We understand that the landslide occurred sometime late on September 15 or early on September 16, 2003. At the time of our visit., we accessed parts of the slide area using the path used for monitoring . the interceptor drainage system. The ground surface on the path was slightly moist, but soils beneath a thin surficial layer were near dry. Areas of wct soil and seepage were observed near the path in areas where year-round seepage is typically present. Heavy rainfall was reported the night of September 15, 2003 by Edmond's residents. Overall rainfall for the weeks preceding the slide has been relatively low. ENVIRONMENTAL ( GEOTECHNICAL I NATURAL RESOURCES 130 2nd Avenue South - Edmonds, WA 98020 - (4Z) 778 C907 - sax (Q5) 778-64,N - wv w.landauinc.com SEArTLE - SPOKANE • TACOMMA - PORTLAND '��'.l5 17E 64UU LAIUAU AUL 1 AItJ IiIL Uyi1J/UJ 14:1J Y.JU3iUUi The landslide has combined block sliding and mudfloA- charactcrist:ics, with an estimated width of about 20 to 30 ft and a total length of 80 ft or greater. The landslide initiated near the top of the bluff, apparently from Lot 4, Sequoia Ridge. The slide initiation is about 20 to 40 ft (vertical) above the City's I nterceptor drainage system IA, CB #8 and about 20 fl north of this catch basin. 'The landslide debris extended about 10 to 20 ft below (west) of CB #6. The estimated elevation of the top of the slide is at about 210 to 220 ft elevation. Several seepage zones could be seen in the exposed bluff in the slide area. The failed soil zone is estimated to be about 3 to 5 ft thick (measured perpendicular to the slope fact). Below the landslide scarp (at the top of the slide), the landslide appears to involve the surftcial layer of soil on the slope along with small to large -sized trees and otter surficial vegetation. The mud flow and vegetative material is currently resting on the slope in the area near catch basins CB #6 and CB 48. The landslide occurred on private property, did not extend to public facilities other than near the City's interceptor drainage system, and did not impact any residences. Soils exposed near the top of the slide area appear to be of glacial origin and consist of outwash sand and gravel overlying fine-grained, silty and clayey- deposits. These conditions are similar to soils exposed in other parts of the Meadowdale area at similar elevations and are similar to conditions observed at other slides in the Lorian Woods/Sequoia Ridge area. The exposed soil after sliding was standing near vertical with a small, shallow, bench visible about 20 ft below the slide scarp. At the time of our visit, defined seepage paths had not yet developed and seepage was observed generally flowing around the mud and debris accumulation at the base of the slide zone. CAUSE, OF SLIDING The bluff in the Mcadowdale area is a known landslide hazard zone. The observed landslide is consistent with other naturally -occurring landslides along the Meadowdale bluff. Most landslides occur during or following an intense rainfall.event during the wet winter season. The observed landslide occurred during or after a short period of intense rainfall, but not during a period of extended wet weather such as typically occurs during the winter., It is possible that the very dry 2003 summer has led to ground cracking that contributed to the landslide occurrence at this time. It is our opinion that the landslide originated in native granular soil above a seepage zone on the steep part of the upper slope. The specific triggering event of the observed landsliding is not ]mown- It is Landau Associates' opinion that the landsliding was caused by a combination of infiltration from a heavy rainfall on the evening and early morning of September 15 and 16, 2003 combined with naturally occurring seepage near the contact between granular sand and gravel deposits and underlying fine-grained 0?.25/03 nEdm..aslwprecW7n114\LoiznWood:Sep%20039,dercv2.dx 2 LANDAuAssoclATEs 5 77 6109 u j i i ui 9 19 r.uu41uui deposits. Both heavy rainfall events and groundwater seepage are common contributing factors to slope failures in the Meadowdale area and throughout Puget Sound. The observed landslide was likely caused by natural groundwater seepage zones that are present in the steep portions of the slope. The lowest seepage zones observed during our visit were an estimated 20 ft above the nearest catch basin, CB ti8, in the City's interceptor drainage system. As discussed in Landau Associates' Drainage Evaluation Lorian Woods/Meadowdale. Area report (July 25, 2002), the City's interceptor drainage systems capture some of the localized surface water that would otherwise infiltrate the ground surface below the drainage system. The interceptor drainage systems do not reduce groundwater levels in the slopes above the systems or reduce seepage from these areas. Accordingly, it is our opinion that the observed landslide was not caused by or related to the City's interceptor drainage system. ]RISK TO CITY OF EDMONDS FACILITIES OR STRUCTURES FROM OBSERVED SLIDE No damage was observed in the existing system 1 A from the September 2003 landslide. The existing landslide does not appear to pose an immediate risk to any other City -owned facilities. However, there is a large accurintlation of very soft and wet soil in the lower part of this landslide. This soil could move furdier downhill if it becomes wetter due to surface water runon or precipitation. However, due to the presence of relatively heavy vegetation in the area, downslope movement is L-xpectcd to be limited. BLUFF CRACKING - SEQUOIA RIDGE PLAT During the site visit, conditions at the top of the bluff above and near the slide were observed. Observations were conducted of the area near the bluff top on the south and west part of Sequoia Ridge Lot 4 and along all of the west edge of Sequoia Ridge Lot 3. No cracks were visible on the ground surface on Lot 4 above the recent slide. However, observations of the ground surface directly above the recent slide area (e.g., within the zone about 3 to 10 A from the slope edge) were not done because of safety concerns_ Ground cracks and small holes were observed in a nearly continuous zone on the west edge of Lot 3 (Bosch residence). In some areas, more than one set of parallel cracks were visible. The ground cracks lie at variable distance away from the edge of the slope, varying from about 3 ft to greater than 10 ft. The ground cracks were observed as close as approximately 10 to 15 ft from the northwest comer of main structure and deck foundations for the Lot 3 residence. The ground cracking adjacent to other parts of the residential structure vary in distance from about 15 to 30 ft away. The ground cracks observed in this area are estimated to lie above Lorian Woods Lot 5, a currently undeveloped lot. 09f25103 1XEarm33A..praCW7411149 oriin woods Upt 2003 ahac rev 2 aoc 3 . LANDAU ASSOCIATES 77`c b40i LAkUA AU L I A I t J II,L uyi13/u6 14:14 r.uu3iuui Vegetation on the north part of Sequoia Ridge Lot 3 includes planted salal and other shrubs. Closer to the house, vegetation includes a well -watered lawn and vegetable beds. The ground cracking varied in distance from the existing structure and from the top of the slope. Most of the cracks showed vertical offset, with the ground surface lower to the west. The ground surface west of the cracks is slightly hummocky and slopes downward to the west. In some areas, concrete landscape retaining blocks had apparently been downset from their original placement, with vertical movement of these blocks estimated to vary between about 3 and 12 inches. The observed ground cracking indicates soil blocks that are no longer "connected" to the intact and undisturbed glacial soil mass east of the cracks. These soil blocks have a relatively high likelihood of movement outtivard and downslope. Based on the distance of observed cracking from the edge of slope, soil blocks of 3 ft to greater than 10 ft thick may be prone to downslope movement. Movement of the soil blocks can be slow or very rapid. Slow movement will be evidenced by increased cracking, opening and offset on cracks that occurs over periods of days, months, and years. Slow ground movement may cause cracks in patios, pavements, and structures that lie over the zone of movement. Rapid ground movement occurs when the soil strength between the soil block and the adjacent undisturbed ground is too low to support the weight of the soil block. Rapid failure of soil blocks occurs over a very short period of time, from a few seconds to a few minutes. There is typically no warning about when and where rapid soil movement will occur. Movement of these soil blocks is most likely during and after periods of high prccipitation in the winter season, but should be anticipated at any time of the year. This type of soil movement is likely to result in landsliding and debris flows sinular to what have been historically observed in the Lorian Woods / Sequoia Ridge area. Homeowners and landowners near the observed cracks in both Sequoia Ridge and Lorian Woods plats should anticipate a high likelihood of soil movement and landsliding from this area over the upcoming winter. R151K TO )ZESIDENTS AND GENERAL PUBLIC FROM OBSERvrD BLUFF CRACKS At the time of our visit, no immediate risk from the observed ground cracks to public safety was identified (because the downslope is undeveloped and the area is not readily accessible to, or used by, the public)_ However, the presence of ground cracking indicates an unstable slope condition that has increased risk of landsliding, particularly during wet weather and the upcoming rainy season. This situation creates a hazard to any person present immediately below the potential landslide area. We recommend that property owners in both Sequoia Ridge and Lorian Woods be informed of our observations and the likelihood of landsliding during the upcoming winter and in future years. The Sequoia Ridge Lot 3 homeownt,T (Bosch) should be informed that their current setback from the edge of slope (as defined by the recent cracking) to the structure and deck foundations at the 0925103 %\Edrmaslvo607411raucr4n Woods Sent 2003 Aide rev Um 4 LANDAu ASSOCIATES northwest corner of the residence is approximately 10 to 15 11. Because the house has been built on deep piles, the presence of these cracks probably does not pose an immediate risk to the stricture. We recommend that the homeowner inform their gcotechnical designer of the presence of active ground cracking so that their designer can provide an assessment of the long-term risk to the structure. We also suggest that the Sequoia Ridge Lot 3 homeowners conduct regular observations of ground conditions to document rate of change of ground cracking. Increased numbers of cracks, opening of cracks, and downward movement of soil blocks are indications that the risk of active landsliding is becoming greater. The Lorian Woods Lot 5 owner should be informed that they could be directly impacted by soil movement and landsliding related to the observed ground cracks on Sequoia Ridge Lot 3. We suggest that information about landslide potential also be conveyed to other residents in the Lorian Woods plat, because large-scale landsliding originating from Sequoia Ridge Lot 3 could create safety concerns and i could affect common areas and potentially other lots. RISK TO CITY -OWNED PROPERTY FROM OBSERVED BLUFF CRACKS At the time of our visit, no immediate risk from the observed ground cracks to City -Owned property was identified. However, the presence of ground cracking indicates an unstable slope condition that has a relatively high risk of landsliding, particularly during wet weather and the upcoming rainy season. The City's drainage interceptor system 1 A Lies downslope of the observed cracks.

Your comments are shown first with my response following shown italicized and bold. The revisions on the construction documents are clouded with a revision bubble and noted as Revision #1. Only the revised sheets have Revision #1 on the title block: 1. See attached city's consulting engineers plan review number 01 comments. / have reviewed the comments and they were forwarded to the respective Civil, Geotechnical & Structural consultants for their use and response. Their responses and adjusted drawings are being submitted with this Architectural response. 2. Drainage behind the interior foundation is required by page 3 of the Landau document. The Sections have been revised to show the required interior foundation drains. Structural Engineering and Civil Engineering plans also have been upgraded to show this requirement. 3. The square footages on Sheet A-1 are incomplete and appear to be inaccurate. For the main and upper floor, the space calculated to 3,560 square feet. The garage came to 759 square feet, and the remainder of the basement needs to be calculated. Provide the math if the numbers substantially differ. The floor plans have been measured under the guidelines you outlined. Although the numbers you calculated are not substantially different than the totals / calculated with the computer, l am still forwarding Floor Plans indicating the location of measurement lines and the associated totals for your use and review. Sheet A-1 has been revised to show these proper square footage totals. 4. Provide a guard at the edge of the storage area to the future shop, as required per R312.1, raised floor surfaces. Garage Level — Sheet A-2 has been revised to show a wood framed 36" high guard wall fastened between the wood posts with gypsum board installed on the future shop side as required to comply with the code. 5. Identify on floor plans all required safety glazing locations. The safety glazing locations are now identified on both plans and elevations. 6. Missing fan in garage bath. The required fan has been added. 7. Missing fan in master bath toilet room. The required fan has been added. ARCHITECTURE - SPACE PLANNING - CONSTRUCTION MANAGEMENT P.O. Box 2907 - Issaquah, WA 98027 - (425) 557-0712 - FAX: (425) 557-0716 8. Construction note 1/A-4 incorrectly requires an insect screen on the dryer exhaust vent, which is prohibited by M1502.2 because of the potential fire hazard of lint building up. The note has been corrected. 9. Detail 9/A-10 calls for the subfloor to be glued and screwed. Screws do not provide the floor diaphragm nailing as required by engineering sheet S-0, and the note should indicate that the screws can't be used in place of nails. The structural engineer reviewed this at my request and found an alternate "Simpson" Series WSNTL #8 screw fasteners that have the required structural properties. Engineering notes on Sheet S-0 have been revised to reflect the screw fastener option. Since I prefer the diaphragm flooring screwed down instead of nailing to help reduce the chance of floor squeaks, I did not change the note on Detail 9/A-10. 10. Provide construction details for the short walls used as guards. Justify how they conform to the 200 lb. top of guard, and the 50 lb. per square foot loads required by code. The structural engineer has addressed this by adding new calculation sheet 14.2 and Section 7 on Sheet S-7. 11. Provide product data for waterstop to be used in foundation keyway per detail 4/S-6. The waterstop is now specified as 6" ribbed flat PVC Shape #679 as manufactured by Greenstreak or approved equal. The specification note has been added to the Section cuts as shown in Architectural Sections. The link to Greenstreak's product catalogue is http://www._greenstreak.comisubpacks/General Waterstop Catalog.pdf. . Please let me know if you require hard copy of this product information. We are anxious to proceed with the construction of this residence for Brian & Cindy. Hopefully, we have addressed all your items properly and look forward to your next review and the building permit.

The GeotecludW 'Engrow indicted that soil design values way be increased 50% for IMpact loads- The wtaming walls.were checked for full height backfill and 1200 PSF bearing (sheets 33A, 33.2B), then for impact loads and 1800 PSF (33B, 33.2A0. The impact loads governed these walls and the mid foundation walls. 3. See addittiotW i dormation from the Geotechnical Engineer. 4. The ACI factors of 1.4 times the dead load and 1.7 times the live loads are applied in the design progmtas for both walls and grade beams. See the calculation printouts. The grade beam deflections, rotation and soil pressure are calculated using un-factored loads per ACI. 5• See revised foundation details 4/S5, 5/S6, 4/S8, 5/S8, 6/S8 and 08 for clear dimcnsions•that reflect ACI standards and those used in the calculations and as noted in the si amwal motes. .6. See revised structural notes to.reflect site class E as used in the.calculations. 7. The submitted calculations for both Walls and grade beams use grade 60 reinforcement steel for all main bars #5 and greater, and grade 40 for all main #4 bars. The temperature re-Morcement bars are detmmined by ACI standards for grade 40 and the member areas. S. See revised shear wall schedule for 1/4"'thick washers. 9.The gravity loads are supported by direct bearing of the foundation on 1200 PSF soil. The grade beams are used as tie beams and designed as load bearing as a redundant safety factor. Tie beams do not require shear reinforcement- FROM, : FAX NO. On. 06 20.10 11:04PM P4 10.

Based on -,our review, our. recommendations have been incorporated. into 'the geotechnical aspects of the plans. ; 4. 2007 Landau Summary Report ; Terra Associates, Inc. discussed, this in our 'report -dated March 31, 2008. On,- Pages 3 and 4, we state: The site, is within the North Edmonds, Earth: Subsidence and- Landslide Hazard Area, as defined by Edmonds Community Development Code , Chapter ,19.10. Our previous study outlines the hazards associated with, development on the property.'. The hazards outlined in the referenced 2007, Landau Associates- study, are consistent with•the hazards outlined in our;previous.study. 'In the prepdrdtion of this report; we have reviewed the referenced 2007 Landau Report: Based 0i our.experience on -site and_our observations in the neighborhood, :we have identified the site'as,being within Zone B•as shown.on Figure 1 of the:2607 Landau report.' The slope immediately east and uphill from the "building site .lies within Zorie C and D. The risk of earth. movement in, the 2007 Landau Report fonZone B consists of. • Encroaching landslide' debris originating upslope ` Reactivation of landslide. debris causing ground failure; and movement • Landsides in ground that has not previously failed Based on our' observations on. the plat since; 1988, we.,concur.that the first two risks of gr' nd'movement are . possible. The' entire site consists of .earth that has moved at. ome time- in the past so the third risk is not applicable on this site. We'analyzed the probability of land sliding. and movement for,ourreport for the plat of Lorian Woods. .We.identified the hazards, of earth movement -in the area upslope from the building lot as, being 5 percent in a 25-year period. We identified the-'riskof rreovement'tivithin the building: lot as being•12'percent in a, 25-year period, Development of the lot .involves an. element of risk' that -the :homeowner, must accept. , Stewardship of the vegetation ' and . drainage facilities on the -site will be 'an, impo"rtani element of, the project over the. life . of the, house. Project No. T-840'- 10 Page No. 2. Mr Brian Isaacson . • June 5, 2009' ; Encroaching Landside Debris Originating Upslope We have, made periodic visits to the plat for geotechnical purposes over the past 20 years. Only one significant '. episode of movement has been documented -to have occurred on or adjacent, to the site in that period. This . movement is the slope failure" that occurred in the winter of 200512006 along the upper.,edge of the slope above the Plat of Lorian Woods. -This failure 'occurred immediately adjacent to a house built in -about 2000. The slope failure resulted in the retreat of the top, of the slope by approximately five to ten feet. We understand that the previous occupant of the house•has moved, the house is vacant, and that the,property has not been fully" evaluated by a geotechnical engineer. .The actualcause of the slope. failure has not been determined.: The 200512606' failure resembled a, toppling or calving of the upper 10 to 15 feet of the slope: All of the soil was either caught behind a cedar log that is* wedged behind a pair of stumps or it mounded up on the -upper portion of the slope immediately,northeast o . the building lot. The'soils from this failure that encroached. onto the building lot and - proposed f 8 proposed building envelope were eroded by:running water and redeposited as sediment lower on the site. Based on our observations on -site, -we, estimate the'volume of failed material as beings about 40 to,50 cubic yards. In the fall, of 2007; the older trees on the, slope above the lot were removed.' A report wds.prepared by Urban' Foresters that -cataloged the diseased trees 'on 'the 'slope.:,'We : expressed our, concurrence -with the tree management and replanting report; prepared -by Urban Foresters dated March 4, -2006. A significant, risk that occurs during. landslides is the action of the trees. ,The trees on. the site that were found to -be diseased or - damaged, have been removed. The restoration of the trees will result in trees that provide a "canopy, but have smaller trunks to reduce the potential for damage from trees that may'become involved in. earth movements. The top of the 'slope, east and, above -the site may be regarded as - a bluff top.. Based on the" observations documented in this report, we estimate that the retreat of ihe,top of the bluff may be on the order of.10 feet per 50-year period.' Unless the uphill neighbor provides mitigation for the recent bluff top retreat, further retreat of the bluff will occur. This'mode of slope, failure can be mitigated with a catchment wall above the proposed,house to stop the landslide debris rom im actin the house. Re ular removal o calved and •eroded soils will be f P 8 8 f required on the slope. above the house over. the life of the structure. We would'expect that the risk of this threat would be reduced in the future by improvements on the' uphill property. . `Provided the recommendations contained in this report: are incorporated into site development pldns, it.is our opinion that the�development will not increase the risk of instability or"the-rate of bluff top, retreat above the site: . 5. Unmitigated Risks On Page 5 of our reportdated Machf,31; 2008; we:.state:. ; Reactivation of Landslide Debris .Causing,.Ground Failure and Movement : In,regards to the risk of movement, of previously failed materials, the second mode -of failure -in the bullet list above, should be, noted that.the house on the lot immediately. south and downhill from the site, has been present since 1964 and 'has•'not. received' levels of damage that. have rendered it unusable. Beneaththe.'house, immediately 'east of the site are houses on'Tax Lots 00513105800500 and, 00100 that have been; present since 1934. Both of these houses are inhabited. While 'this: does not indicate the lack of movement, 'it does, illustrate , that the, magnitudes of movements that have occurred. have been manageable or, are .within. the tolerances of the.

The design team for this project is: Western Engineer, Inc; Barry R. Constant, P.E.; Project Manager, Civil Engineer Terra Associates; Chuck Lie, Geotechnical Engineer Reed and Associates, Inc.; Wendel Reed, Structural Engineer Landscape Architect; Jennifer Lee, Licensed Professional As the lead design Professional Engineer providing services to our client, Mr. & Mrs. Brian Isaacson, my team and I have reviewed the geotechnical report and understand it's recommendations and have incorporated these design recommendations into the site civil design of this project. The design parameters that my team and 1 have designed for the civil drawings are using industry standard design measures to reduce the potential risk of injury or damage from any earth movement predicted in the report. Although the recommendations in the geotechnical report, will have been followed during the construction on this site, this engineer does not guarantee the long-term maintenance of these items. These maintenance items are under the control of the client and not under direct supervision by myself. Maintenance will be required as long as there are no installed permanent solutions to the landslide hazard area. And further: in my judgment, the plans and specifications prepared by the structural engineer conform to the recommendations in the geotechnical report. LAND USE CONSULTANTS • CIVIL ENGINEERS • LAND SURVEYORS • ENGINEERING CORPORATION • 0 That the risk of damage to the proposed development, or to adjacent properties, from soil instability will be minimized subject to the conditions set forth in the report and that the proposed development will not increase the potential for soil movement. Minimized shall mean that the applicant has utilized best available science and commonly accepted engineering and architectural practice to minimize, to the extent possible, the risks associated with development of the property. The risk of onsite soil movement in the building site area probability within the next 25- years is approximately 12 percent. This is based on long-term study by our team geotechnical engineer (Mr. Chuck Lie) who personally has studied this landslide hazard area for 20-years. By studying the various geotechnical reports issued for the site over the last 20-years and using common and standard engineering practices for the erosion and sedimentation control, as well as the long term drainage solutions engineered and incorporated into the site will minimize land movement activities. Please see letter from the landscape architect for additional information The upper catchment wall, as designed by Reed and Associates, Inc. with assistance from Chuck Lie has been designed to stop low velocity landslide activated soils from contacting the house structure. An onsite deep boring was advanced in the area of the proposed wall. This wall has three feet of exposed wall above a very deep soldier pile support structure. The site is designed to allow a small, lightweight powered or unpowered wheeled container to remove any soil spoils from the upper wall area and transport them down slope safely. This type of maintenance is not guaranteed by this letter. Please see letter from the landscape architect for additional information The Landscape Architect will provide deep-rooted planting that remove water from the loose upper soils on site. The landscaping will also provide small trees to provide the same function. Please see letter from the landscape architect for additional information The Landau Geotechnical report, dated 2007, identified certain areas as landslide hazards for this site and certain recommendations to reduce and minimize these hazards. Western Engineers in conjunction with Terra Associates have reviewed, designed and approved the site engineering for the house structure location and elevations, retaining walls and catchment wall above the retaining walls. We have reviewed all structural and retaining wall footing drains and provided an extensive underground drainage conveyance system capable of removing and directing any runoff away from the house structure and retaining walls, down slope directly into the City drainage system on the roadway below the new house. Reducing and removing storm water runoff from the soils onsite is the number one risk reduction factor associated with earth movement. No one has control over the potential for shallow or deep-seated earthquake induced land movement, but we have reduced the ability of the land to move on pressurized (water pressure) underground soils, which could enhance additional land movement. The attached soil boring water levels and the attached information regarding the piezometer reading all indicate that the existing ground water levels has been reduced over time. Please call me or any of the design team if you have questions regarding this letter. Sincerely, Western Engineers, Inc. Barry onstant, P.E.

Appendix B • Geotechnical Report Lorian Woods Lot 2 Lorian Woods Edmonds, Washington 1.0 PROJECT DESCRIPTION The proposed project is a single-family dwelling. We were provided with architectural drawings indicating the location of the home on the lot and elevations of the foundations. The home is. located in the western portion of the lot. The structure is a two-story, wood -framed building with its main floor framed over a garage and crawl space. .The garage floor will be constructed at grade. We expect foundation loads will be relatively light, in the range of 2 kips per foot for bearing walls and 25 kips for isolated columns. The site grading will consist of cuts of u.p to eight feet to achieve the garage elevation. Nominal cuts will be needed .to prepare the balance of the house site. There will be a catchment wall constructed on the east side of the property approximately ten feet west of the property line to protect the home from landslides. We previously prepared a report entitled Geotechnical Report, Meadowdale Beach Lots 54 through 57, Edmonds, Washington, Project T-840-1, dated June 6, 1989. This previous report was written as part of the plat recording process for Lorian Woods. Lorian Woods is located within an area that has been subjected to past earth movements. The risks of earth movements are addressed in our previous report and must be accepted by the homeowner. We also prepared a letter dated August 7, 2006 that addressed tree removal and maintenance on this site. The recommendations contained in the following sections of this report are based on our understanding of these design features. If actual features vary or changes are made, we should review them in order to modify our recommendations, as required. We should review final design drawings and specifications to verify that our recommendations have been properly interpreted and incorporated into project design. 2.0 SCOPE OF WORK Our original work was completed in accordance with our proposal, dated August 27, 2004. On November 8, 2004, we excavated 2. test pits to a. maximum depth of 11.5 feet below existing surface grades. On February 27, 2008, we supplemented this data by. drilling one 40-foot test boring. Using the information obtained, from the previous and current subsurface exploration, we performed analyses to develop geotechnical recommendations for project design and construction. Specifically, this report addresses the following: • Soil and groundwater conditions • Site preparation and grading • Excavations • Foundations • Slab -on -grade floors • Retaining walls/catchment wall • Drainage 0 March 31, 2008 Project No. T-840-10 It should be noted that the recommendations outlined in this report regarding drainage are associated with soil strength, design earth pressures, erosion, and stability. Design and performance issues with respect to moisture as it relates to the structure environment (i.e., humidity, mildew, mold) are beyond Terra Associates' purview. A building envelope specialist or contractor should be consulted to address these issues, as needed. . 3.0 SITE CONDITIONS 3.1 Surface The building site is located in the Lorian Woods development, south of North Meadowdale Road, near the 7400 block in Edmonds, Washington. The building site is located on Lot 2 and is currently developed. The approximate location of the site is shown on Figure 1. The portion of the lot containing the building site slopes down to the west at grades ranging from 10 to 50 percent. Along the eastern portion of the lot and east of the building site, the site slopes up with surface grades that are nearly vertical for short heights. The site is thickly forested with mature alder, maple, cedar, and fir trees. The large trees were removed from the site in the fall of 2007. Several.of the trees were chipped. The chips were used to mulch the site. The site.is bordered with undeveloped lots to the north and south, an existing residence along the top of the slope to the east, and an asphalt driveway servicing the Lorian Woods development to .the west. During our exploration, we observed surface water flowing across the building site area. The surface.water was flowing from the slope located east uphill of. the building area. The seepage had been partially controlled.by a City of Edmonds seepage collection system. In the winter of 2005/2006, there was a small landslide that originated uphill from the plat of Lorian Woods. This landslide damaged the upper end of the collection system. 3.2 - Soils The soils we observed in the test pits generally consist of 12 to 24 inches of topsoil overlying colluvial soils. The colluvial soils consisted of loose to medium dense silty sand with occasional gravel, organics, and blocks of silt. We observed- large -diameter,, nested logs in Test Pit TP-2 at a depth of approximately nine feet below existing surface grades. The soils.observed in the supplemental test boring were consistent with the soils observed in the previous test pits. The loose to medium dense silty sand with gravel, organics, and blocks of silt were observed, along with some layers of loose to medium dense sand with silt layers and gravel to a depth of 40 feet. At 40. feet, we observed hard clay that we interpreted to be transitional bed soils not impacted by the historic landsliding. Page No. 2 • March 31, 2008 Project No. T-840-10 For a more detailed description of the soil conditions observed at the test pits and :test boring, please refer to the logs attached in Appendix A. The approximate test pit and boring locations are shown on Figure 2. , The Preliminary Surficial Geologic Map of the Edmonds East and Edmonds West Quadrangles, Snohomish and King Counties, Washington, by Mackey Smith,1975, shows soils in the vicinity of the site consisting of Old landslides (Qols). The soils observed in the test pits and test boring are consistent with this classification. 3.3 Groundwater We did not observe groundwater seepage in. any of the test pits. However, we observed mottled, wet soils in the upper portions of test pits and layers of saturated sand material throughout the test boring. Perched groundwater levels and flow rates will fluctuate seasonally and typically reach their highest levels during and shortly following the wet winter months (October through May). City of Edmonds piezometer P-17 is near the southwest corner of Lot 2. The city has measured the depth to static water level over the past several years. The boring log for the piezometer and the city memo is attached in Appendix B. Oh February 27, 2008, we measured the groundwater in piezometer P-17 to be at a depth of 5.88 feet below top of casing. The top of the casing is about one -inch below the top of the monument cover. 4.0 GEOLOGIC HAZARDS 4.1 Landslide Hazard General The site is within the North Edmonds Earth Subsidence and Landslide Hazard Area, as defined by Edmonds Community Development Code Chapter 19.10. Our previous study outlines the hazards associated with development on the property. The hazards outlined inthe referenced 2007 Landau. Associates study are consistent with the hazards outlined in our previous study. In the preparation of this report, we have reviewed the referenced 2007 Landau Report. Based on our experience on -site and our observations in the neighborhood, we have identified the site as being within Zone B as shown on Figure 1 of the 2007 Landau report. The slope immediately east and uphill from the building site lies within Zone C and D. The risk of earth movement in the 2007 Landau Report for Zone B _consists of: • Encroaching landslide debris originating upslope • Reactivation of landslide debris causing ground failure and movement • Landsides in ground that has not previously failed Page No. 3 March 31, 2008 Project No. T-840-10 Based on our observations on the plat. since 1988, we concur that the first two risks of ground movement are possible. The entire site consists of earth that has moved at some time in the past so the third risk is not applicable on this site. We analyzed the probability of landsliding and movement for our report for the plat of Lorian Woods. We identified the hazards of earth movement in the area upslope from the building lot as being 5 percent in a 25-year period. We identified the risk of movement within the -building lot as being 12 percent in a 25-year period. Development of the lot involves an element of risk that the homeowner must accept. Stewardship of the vegetation and drainage facilities on the site will be an important element of the project over the life of the house. Encroaching Landside Debris Originating Upslope We have made periodic visits to the plat for geotechnical purposes over the past 20 years. Only one significant episode of movement has been documented to have occurred on or adjacent to the site in that period. This movement is the-slope#failureathat occurred in the winter of 2005/2006 along the upper edge of the slope above the Plat of Lorian Woods. This failure occurred immediately adjacent to a house built in about 2000. The slope failure resulted in the retreat of the top of the slope by approximately five to ten feet. We understand that the previous occupant of the house has moved, the house is vacant, and that the property has not been fully evaluated by a geotechnical engineer. The actual cause of the slope failure has not been determined. The 2005/2006 failure resembled a toppling or calving of the upper 10 to 15 feet of the slope. All of the soil was either caught behind a cedar log that is wedged behind a pair of stumps or it mounded up on the upper portion of the slope immediately northeast of the building lot.. The soils from this failure that encroached onto the building lot and proposed building envelope were eroded by running water and redeposited as sediment lower on the site. Based on our observations on -site, we estimate the volume of failed material as being about 40 to 50 cubic yards. In the fall of 2007, the older trees on the slope above the lot were removed. A report was prepared by Urban Foresters that cataloged the diseased trees on the slope. W`.pressedourconcurrenc wththe fremanagement =and replan in report ;prepared -by. "Forester d%a[ed-March 4, 2006. A significant risk that occurs during landslides is the action of the trees. The trees on the site that were found to be diseased or,damaged have been removed. The restoration of the trees will result in trees that provide a canopy, but have smaller trunks to reduce the potential for damage from trees that may become involved in earth. movements. The top of the slope east and above the site may be regarded °asZa=bluff*top. Based on the observations documented in this report, we estimate that the retreat of the top of the bluff may be on the order of 10 feet per 50-year period. U,nlessAtheIjuphill,neig . beraprovidespmiti'gatib fortthe -re ent ,,bluff,top retrea ,"1 rtl er"retreat of .thenbluffw<ill,occur�. This mode of slope failure can be mitigated with a catchment wall above the proposed house to stop the landslide debris from impacting the house. Regular removal . of calved and eroded soils will be required on the slope above the house over the life .of the structure. We would expect that the risk of this threat would be reduced in the future by improvements on the uphill property. Provided the recommendations contained in this report are incorporated. into site development plans, it is our opinion that the development will not increase the risk of instability or the rate of bluff top retreat above the site. Page No. 4 • Reactivation of Landslide Debris Causing Ground Failure and Movement March 31, 2008 Project No. T-840-10 In regards to the risk of movement of previously failed materials, the second mode of failure in the bullet list above, should be noted that the house on the lot immediately south and downhill from the site has been present since 1964 and has not received levels of damage that have rendered it unusable. Beneath the house, immediately east of the site are houses on Tax Lots 00513105800500 and 00100 that have been present since 1934. Both of these houses are inhabited. While this does not indicate the lack of movement, it does illustrate that the magnitudes of movements that have occurred have been. manageable or are within the :tolerances of the structures' foundations. To mitigate against possible shifting within the landslide mass, the house will be built on a rigid grid foundation. It is beyond the scope of construction on a single lot to mitigate the possible deep-seated movements that could occur into the future. If groundwater levels are found to rise in the permanent city piezometers, the neighborhood would need to as a group install drainage facilities such as horizontal wells to maintain the water table at or below the current levels. Provided the recommendations contained in this report are incorporated into site development plans, it is our opinion that the development will not increase the risk of instability on the site or on adjacent properties. 4.2 Seismic Based on the Edmond Municipal Code 23.80.020, the site is within a seismic hazard area. This classification is due to the presence of potentially liquefiable soils beneath the site. Our review of maps showing current faults shows that there are no known or suspected faults as being within three miles of the site. Current mapping shows that the closest faults are the South Whidbey faults that extend diagonally across south Whidbey Island and extend through the Mukilteo area north of the site. This mapping is based on information in the Map and Data for Quaternary Faults and Folds in Washington State prepared by the USGS, open file report 03-428. Based on our knowledge of soil conditions and local geology, per Chapter 16 of the 2006 International Building Code (.I site -_cola s4"E',,�Should be;used in .the project s"�stn c_ fural;de gn. Liquefaction is a phenomenon where there is a reduction. or complete loss of soil strength due to an increase in water pressure induced by vibrations. Liquefaction mainly affects geologically, recent deposits of fine-grained sands that are below the groundwater table. Soils of this nature derive their strength from intergranular friction. The generated water pressure or pore pressure essentially separates the soil grains. and eliminates this intergranular friction, thus eliminating the soil's strength. Based on our knowledge of the soil and groundwater conditions, it is our opinion that there is a risk for liquefaction to occur at this site. during an earthquake. The risk from liquefaction would exhibit itself as differential settlements in the building. The proposed building will be built on a rigid grid foundation to mitigate for possible lateral shifts due to land subsidence from landsliding. This mitigation will also mitigate against the risk of foundation settlement due to liquefaction. Page No. 5 March 31, 2008 Project No. T-840-10 4.3 Erosion Based on the Edmond Municipal Code 23.80.020, the site is within anerosion hazard area. This classification is based on slope inclination and the presence of seepage on the site. The site has had tree removal performed in accordance with a tree removal plan prepared by others. The site was mulched following the removal of the trees. We have not observed any signs of erosion related issues on the site over the course of the winter of 2007/2008 including a site visit following the heavy rains of the first week of December 2007. Development of the site will include a temporary erosion and sediment control plan. Erosion will be managed through the construction period using established BMPs. 5.0 DISCUSSION AND RECOMMENDATIONS 5.1 General As noted earlier, the site is in a mapped landslide hazard area. Relative risks of slope movement are discussed in our June 6, 1989, report and in the 2007 Landau Associates Summary Report. Provided the owner is willing to accept the risks associated with slope instability at the site, in our opinion, the site conditions are suitable for the proposed construction. We recommend the structure be supported on a mat/raft foundation, bearing on the existing colluvial soils or on structural fill placed above these colluvial soils. A surface swale should be constructed along the uphill side of the house above the proposed landslide catchment wall. The swale should span the entire width of the building area and discharge into the Plat storm system. The catchment wall indicated on the drawings should conform to the design recommendations outlined on Figure 4. The site soils contain significant amount of fines and will be difficult to compact as structural fill when too wet. The ability to use native soil from site excavations as structural fill will depend on the soil's moisture content and the prevailing weather conditions at the time of construction. If grading activities take place during the winter season, the owner should be prepared to import free -draining granular material for use as structural fill and backfill. No fill may be placed that will raise existing site grades. All soils excavated from this site and not used as backfill must be removed from the site. The large cedar log and accumulated soils along the upper slope should be removed. This work will need to be done using either by hand or light weight equipment. The soils and log should be removed from the site. Detailed recommendations regarding these issues and other geotechnical design considerations are provided in the following sections of this report. These recommendations should be incorporated into the final design drawings and construction specifications. Page No..6 • • 5.2 Site Preparation and Grading March 31, 2008 Project No. T-840-10 To. prepare the site for construction, all vegetation, organic surface soils, and other deleterious materials should be stripped and removed from the building area. Organic topsoil will not be suitable for use as structural. fill, but may be used for limited depths in nonstructural areas: Once clearing ' and stripping operations are complete, excavation can be initiated to establish desired grades. Final site grades should be either the same as existing site grades or lower. No fills should be placed on -site that result in raising existing site grades.. Soils excavated from the site that are not needed for foundation backfill must be exported from the site. Following excavation, all exposed bearing surfaces should be observed by a representative of Terra Associates. If excessively soft areas are observed and cannot be stabilized in place by compaction, the affected soils should be excavated and removed to firm bearing and grade restored with new structural fill. If the depth of excavation to remove unstable soils is excessive, use of a geotextile reinforcing/separation fabric, such as Mirafi 500X or equivalent, can be considered in conjunction with clean granular structural fill. Our experience has shown that, in general, a minimum of 18 inches of a clean, granular structural fill over the geotextile fabric should establish a stable bearing surface. Our study indicates that the colluvial soils contain a significant percentage of fines (silt -and clay -sized particles), which makes them difficult to compact as structural fill if they are too wet or too dry. Accordingly, the ability to use native soils from site excavations as structural fill will depend on their moisture content and the prevailing weather conditions when site grading activities take place. If grading activities are planned during the wet winter months, or if they are initiated during the .summer and extend into fall and winter, the owner should be prepared to import wet weather structural fill. For this purpose, we recommend importing a clean granular soil that meets the following grading requirements: U.S. Sieve Size Percent Passing 6 inches 100 No. 4 75 maximum No. 200 5 maximum* *Based on the 3/4-inch fraction. Prior to use, Terra Associates, Inc. should examine and test all materials imported to the site for use as structural fill. Structural fill should be pT' ced in uniform loose layers not exceeding 12 inches and compacted to a minimum of 95 percent of the soil's maximum dry density, as determined Fy—=eFi an Society for Testing and Materials (ASTM) Test Designation D-698 (Standard Proctor). The moisture content of the soil at the time of compaction should be within two percent of its optimum, as determined by this ASTM standard. In nonstructural areas, the degree of compaction can be reduced to 90 percent. Page No. 7 • 5.3. Excavations March 31, 2008 Project No. T-840-10 All excavations at the site .associated with confined spaces (such as utility trenches) must be completed in accordance with local, state, or federal requirements. Based on current Occupational Safety and Health Administration (OSHA) regulations, the loose to medium dense colluvial soils would generally be classified as Type "C" soils. Accordingly, side slopes on temporary excavations. should be laid back at.a gradient of 1.5:1. (Horizontal:Vertical) or flatter.. If these slope inclinations cannot be achieved due to site constraints, temporary shoring may be required. Depending on the time of year and weather conditions when excavations take place, groundwater seepage may be encountered within excavations extending deeper than one -foot below existing surface grades. Based on our study, the volume of water and rate of flow into the excavation should be relatively light, depending on the time of year and the height of the exposed seepage face. Dewatering using conventional sump -pumps should be adequate in maintaining a relatively dry excavation. This information is provided solely for the benefit of the owner and other design consultants, and should not be construed to imply that Terra Associates, Inc. assumes responsibility for job site safety. It is understood that job site safety is the sole responsibility of the project contractor. 5.4 Foundations We recommend the structure be supported on a raft foundation consisting of a connected grid of grade beams that bear on the existing colluvial soils or on structural fills placed above these soils. No isolated column pads should be used for structural support. We recommend designing this foundation for a net allowable bearing capacity of il�!20ipounds�ver squa"re foo �(psf). For short-term loads, such as wind and seismic, a one-third increase in this & USI allowable capacity can be used. Foundation subgrades should be prepared, as recommended in Section 5.2 of this report. Perimeter foundations exposed to the weather should bear at a minimum depth of 1.5 feet below final exterior grades for frost protection. For designing foundations to resist .lateral loads, a base friction coefficient of 0.35 can be used. Passive earth pressures acting on the sides of the footings can also be considered. We recommend calculating this lateral resistance using an equivalent fluid weight of 250 pounds per cubic foot (pcf). We recommend not including the upper 12 inches of soil in this computation .because it can be affected by weather or disturbed by future grading activity. This value assumes the foundations will be constructed neat against competent soil and backfilled with structural fill, as described in Section 5.2 of this report. The values recommended include a safety factor of 1.5. 5.5 Slab -on -Grade Floors Slab -on -grade floors may be supported on subgrade, as recommended in Section 5.2 of this report. Fill should not be placed to raise site grades above the existing elevations to support slab -on -grade floors. If the main level. floor will be above existing site grades, we recommend the use of raised wood floors framed over a crawl space. Page No. 8 LI 0 March 31, 2008 Project No. T-840-10 Immediately below slab -on -grade floors, we recommend placing a four -inch thick capillary break layer of clean, free -draining, coarse sand or fine gravel that has less than three percent passing the No. 200 sieve. This material will reduce the potential for upward capillary movement of water through the underlying soil and subsequent wetting of the floor slabs. The. capillary break layer will not prevent moisture intrusion through the slab caused by water. vapor transmission. Where moisture by vapor transmission is undesirable, such as covered floor areas, a common practice is to place a durable plastic membrane on the capillary break layer and then cover the membrane with a layer of clean sand or fine gravel to protect it from damage during construction, and to aid in uniform curing of the concrete slab. It should be noted that if the sand or gravel layer overlying the membrane is saturated prior to pouring the slab, it will be ineffective in assisting uniform curing of the slab and can actually serve as a water supply for moisture transmission through the slab and potentially affect floor coverings. Therefore, in our opinion, covering the membrane with a layer of sand or gravel should be avoided if floor slab construction occurs during the wet winter months and the layer cannot be effectively drained. Other methods are available for preventing or reducing water vapor transmission through the slab. We recommend consulting with a building envelope specialist or contractor for additional assistanceregarding this issue. 5.6 Retaining Walls The magnitude of earth pressure development on below -grade walls, such as basement walls, will partly depend on the quality of the wall backfill. We recommend placing and compacting wall backfill as structural fill. Wall backfill below structurally loaded areas, such as pavements or floor slabs, should be compacted to a minimum of 95 percent of its maximum dry density, as determined by ASTM Test Designation D-698 (Standard Proctor): In unimproved areas, the relative compaction can be reduced to 90 percent. To guard against hydrostatic pressure development, drainage must be installed behind the wall. A typical wall drainage detail is shown on Figure 3. With. wall backfill placed and compacted as recommended and drainage properly installed, unrestrained walls can be designed for an active. earth pressure equivalent to a*fluidjweighing-35 pcf. For restrained walls, an additional uniform lateral prgssurevofw1.00eips&should,A,be�included. _For evaluation of below -grade,, alls_under seismiy loading, a�'n additional uniform load equal to 8H psf, where H is the below -grade height of the wall can be used. These values?assume horizontal„backfill3condition��and�that no other su charge loading (such as traffic, sloping emu. embankments, or adjacent buildings) will act .on the wall. If such conditions exist, the imposed loading must be included in the wall design. Friction at the base of the wall foundation ad pass . iVFTMTh-pFe&sure will provide resistance to these lateral loads. Values for these parameters are provi ed in Section 4.4 of this report. 5.7 Catchment Wall A landslide catchment retaining wall. is to be built on the east side of the home.. Recommended soil parameters for design are shown on Figure 4. We recommend drainage board be placed as shown on Figure 3 to prevent hydrostatic pressure from developing behind the buried portion of the wall. Page No. 9 March 31, 2008 Project No. T-840-10 The catchment wall, as currently designed, should be adequate in protecting the property from soil instability discussed earlier in this report. With this wall and the other recommendations outlined in this report, implementing the proposed development will not increase the potential for soil movement, in our opinion. Any soil or sediments that accumulate above the catchment wall will need to be fully removed in a timely ` manner. We recommend that removal be planned to occur within one to two weeks of deposition. All soils from above the wall will need to be disposed of off -site. 5.8 Drainage Surface Final exterior grades should.promote free. and positive drainage away from the building area. We recommend providing a gradient of at least three percent for a minimum distance of ten feet from the building perimeter, except in paved locations. In paved locations,.a minimum gradient of two percent should be provided, unless provisions are included for collection and disposal of surface water adjacent to the structure. All downspout drains need to be collected in tightlines and be routed to the plat storm drainage system. We recommend the use of rigid pipe for all tightlines. Cleanups should be provided every 20 feet to facilitate maintainace of the drains. All downspouts and gutters should be kept clear and free flowing at all times. To prevent surface. water flowing off the adjacent hillside from impacting foundations, we recommend installing a surface swale along the uphill side of the catchment wall. The Swale should extend the entire width of the wall and convey surface water to an appropriate point of controlled discharge into the .plat stormwater system located in the street below the site. The collected surface water should not be discharged into the existing slope drainage system currently operating along the south side of the building site. A surface seepage collection system is being designed by We Engineers. The system will replace the upper portion of the former City of Edmonds seepage collection system that was damaged in the previous earth movements. The new system will rely on the use of surface collection troughs and flexible HDPE collection pipes. The use of surface pipes will facilitate maintenance and will allow flexibility of the collection system. The surface drainage system should be maintained on a regular basis. This will include shifting or adding troughs. All surface seepage and runoff collected on -site must be routed to the site storm drainage system. If water features are included in the final site layout along the house, the channels to carry surface water must be lined with a welded HDPE membrane. A detail for use in the design of surface water features is shown in the drawing entitled City of Edmonds Lorian Woods Drainage Collection prepared for the City of Edmonds by R W Beck, dated June 4, 2003. No infiltration of surface runoff should be allowed to occur. Subsurface We recommend installing a continuous drain along the outside lower edge of the perimeter building foundations. The foundation drains should be tightlined separately from the roof drainage system and discharge into the plat stormwater system located in the street below the site. Subsurface drains must be laid with a gradient sufficient to promote positive flow to the point of discharge. All drains should be provided with cleanouts at easily accessible locations. These cleanouts should be serviced at least once every year. Page No. 10 March 31, 2008 Project No. T-840-10 5.9 Slopes and Embankments All permanent cut slopes should be graded with a finished inclination of no greater than 3:1. No fill slopes should be created on the site. The existing near -vertical exposure of soil at the eastern point of the building envelope should be regraded through cutting to flatten the slope to a 3:1 slope or flatter. Upon completion of grading, the slope face should be trackwalked and appropriately vegetated or provided with other physical means to guard against erosion. Final grades at the top of the slope must promote surface drainage away from the slope crest. Water must not be allowed to flow uncontrolled over the slope face. If surface runoff must be directed towards the slope, the runoff should be controlled at the top of the slope, piped in a closed conduit installed on the slope face, and taken to an appropriate point of discharge beyond the toe. 6.0 ADDITIONAL SERVICES Terra Associates, Inc. should review the final project designs and specifications in order to verify that earthwork and foundation recommendations have been properly interpreted and incorporated into project design. We should also provide geotechnical services during construction to observe compliance with our design concepts, specifications, and recommendations. This will allow for expedient design changes if subsurface conditions differ from those anticipated prior to the start of construction. 7.0 LIMITATIONS We prepared this report in accordance with generally accepted geotechnical engineering practices.

On February 27, 2008, we supplemented this data by drilling one 40-foot boring. The approximate test pit locations are shown on Figure 2. The Test Pit Logs and Boring Logs are presented on Figures A-2 and A-3. A geotechnical engineer from our office conducted the field exploration, maintained a log of each test pit, classified the soils encountered, collected representative soil samples, and observed pertinent site features. Our representative classified the soil conditions encountered, maintained a log of each test boring, obtained representative soil samples, and recorded water levels observed during drilling. During drilling, soil samples were obtained in general accordance with ASTM Test Designation D-1586. Using this procedure, a 2-inch (outside diameter) split barrel sampler is driven into the ground 18 inches using a 140-pound hammer free falling a height of 30 inches. The number of blows required to drive the sampler 12 inches after an initial 6-inch set is referred to as the Standard Penetration Resistance value or N value. This is an index related to the consistency of cohesive soils and relative density of cohesionless materials. N values obtained for each sampling interval are recorded on the Boring Logs, Figure A-3. All soil samples were visually classified in accordance with the Unified Soil Classification System (USCS) described on Figure A-1. Representative soil samples obtained from the test pits and boring were placed in sealed containers and taken to our laboratory for further examination and testing. The moisture content of each sample was measured and is reported on the Test Pit Logs and Boring Logs. Grain size analyses were performed on two samples. The results are shown on Figure A-4.

E., Assistant City Engineer City of Edmonds Development Services Department, Engineering Division FROM: Dennis R. Stettler, P.E. DATE: January 24, 2007 R. PIEZOMETER INSTALLATION AND DRAINAGE RECOMMENDATIONS LORIAN WOODS SUBDIVISION EDMONDS, WASHINGTON INTRODUCTION AND PROJECT BACKGROUND This technical memorandum presents the results of a piezometer installation within a portion of the Lorian Woods Subdivision and an assessment of the groundwater conditions with respect to proposed modifications to the drainage system. The purpose of these services was to evaluate the current groundwater conditions and to provide consultation to the City of Edmonds (City) related to the design and construction of a replacement drainage system. The piezometer was installed on the paved shoulder of 73 d Place West, about 250 R south of the intersection of 73d Place West and North Meadowdale Beach Road. The piezometer location is shown on the Site and Exploration Plan, Figure 1. The Lorian Woods Subdivision is within the designated North Edmonds Earth Subsidence and Landslide Hazard Area, and control of surface water and groundwater in the area improves overall slope stability. Springs and groundwater seepage from the steep bluff on the east side of the Lorian Woods subdivision had been collected by a surface water collection system (Drainage System 1 A) constnicled at the base of the bluff by the City as a part of Local hoprovement District (LID) drainage improvements completed -in the 1980s. Landslides, originating on the bluff above the drainage collection system on and above Lot 2 and the adjacent.common area to the south of Lot 2 in the Lorian Woods Subdivision, have destroyed or damaged portions of the drainage collection system. The landslides are the result of a very steep bluff face and the presence of seepage on the bluff. The landslides are occurring above the drainage system and are not related to the presence or function of the drainage system (the drainage system is intended to improve slope stability conditions below the drainage system). The recurring Iandslides from above the drainage system, the presence of landslide debris, and leaning trees on the steep slope have created a hazardous work area for City workers to repair or replace the drainage system in its original location. The City is considering alternate drainage systems as a replacement for the existing system (Drainage System IA). This could include working with the property 130 2nd Avenue South .

The private drainage system would then feed into the City system. Previous conceptual surface water drainage systems for this location have included consideration of a shallow groundwater drainage system. If shallow groundwater is present, it would be appropriate to construct a subsurface drainage component into the new drainage system to intercept groundwater and convey it to the City collection system. However, limited groundwater information was available to know the depth of groundwater near the proposed surface water drainage system, and the City requested that Landau Associates install a piezometer at this location in order to measure the groundwater level. SCOPE OF SERVICES Landau Associates'. scope of services included installation of a piezometer to monitor groundwater levels and consultation related to the design and construction of a replacement drainage system. Our services were provided in accordance with Task Order No. 06-05 under the On -Call Geotechnical Engineering Services Agreement between the City of Edmonds and Landau Associates. The scope of services included: • Drilling a boring to a depth of about 20 ft and installing a piezometer using a licensed well driller under subcontract to Landau Associates to monitor groundwater levels. • Coordinating the boring and piezometer installation by a Landau Associates geotechnical engineer, including locating the boring,, checking the boring location for buried utilities using the one -call public utility locate system, monitoring the drilling of the boring, preparing a log of the boring noting the soil and groundwater conditions, and observing the installation of the piezometer: • Monitoring the groundwater level in the piezometer three times after completion of the piezometer installation. After that time, the piezometer can be included with the system of other piezorneters in the North Edmonds Earth Subsidence and Landslide Hazard Area that are monitored by City personnel. • Preparing this technical memorandum that provides a log of the boring and monitoring well, the installation procedures, and the results of. groundwater monitoring. • Providing additional consultation related to design and construction of drainage measures. FrELD EXPLORATIONS Subsurface Conditions at the project site were explored on October 2, 2006. The exploration program consisted of advancing and sampling one exploratory boring and installing a piezometer (P-17) at the approximate location illustrated on the Site and Exploration Plan, Figure 1. The exploratory boring 0,24107 ma�uo�oc,sw�ni�,cazwwivia�r�ezaruunu�, an acc In A DrxjlkFT 2 J2/.17`/2007 15:21 F.4A 425 778&9 HANSEN BICLAUGHLIN 1�J009 i a' ; was advanced to a depth of about 21.5 13 below the existing ground surface (BGS) using hollow -stem auger drilling techniques. Holocene Drilling, Inc. of Graham, Washington, under subcontract to Landau Associates, advanced the boring. The exploration was located approximately in the field by hand taping from existing physical features and referenced to a site map provided by the City. The ground surface elevation at the exploratory boring location was interpreted from the elevation contours on the site map provided by the City (which is referenced to an arbitrary benchmark). The field exploration program was coordinated and monitored by a Landau Associates geotechnical engineer whoalso obtained representative soil samples, maintained a detailed record of the subsurface soil and groundwater conditions, and described the soil encountered by visual and textural examination. Each representative soil type observed in our exploratory boring was described using the soil classification system shown on Figure 2, in general accordance with American Society for Testing and Materials (ASTM) D2488, Standard Recommended Practice far Description of Soils (Visual -Manual Procedure). A summary log of the exploratory boring is presented on Figure 3. This log represents Landau Associates' interpretation of subsurface conditions identified during the field exploration program. The stratigraphic contacts shown on the summary log represent the approximate boundaries between soil types; actual transitions may be more gradual. The soil and groundwater conditions depicted on the summary log are only for the specific date and location reported, therefore, are not necessarily representative of other locations and times. Disturbed samples of the soil encountered in the exploratory boring were obtained at selected intervals using a 1.5-inch inside -.diameter Standard Penetration Test split -spoon sampler. The sampler . was driven up to 18 inches into the undisturbed soil abead of the auger with a 140-lb hammer falling a distance of approximately 30 inches. The number of blows required to drive the sampler for the final 12 inches of soil penetration, or part thereof, is noted on the boring log, adjacent to the appropriate sample notation. Samples collected in this mariner were taken to our laboratory for further examination and testing. Upon completion of drilling and sampling, a piezometer consisting of a 2-inch diameter, schedule 20 PVC well casing with a 10 R length of 0.010 inch machine slotted well screen was installed. Sand pack was installed around the screen section and bentonite chips were installed above the screened section extending up to the approximate Existing grade. The top of the piezometer was fitted with a monument cover installed flush with the pavement and the pavement patched with concrete. The borehole and piezometer (well) was installed in general accordance with the requirements of Washington Administrative Code (WAC) 173-160. 07Q4107 pEdmdUL2�)MjnctcW74111510201WVftPieminrtaMon bn.doc D _R_A_ F T 3 :1tLp 77%2007 15:21 FAX 425 7r8V9 HANSEN t1CLAUGHLIN U005 SOIL AND GROUNDWATER CONDITIONS Soil that was interpreted to be landslide debris was disclosed for the full depth of the boring (21.5 BGS). This condition was consistent with our expectations given the geologic history and the results of previous- explorations in the area. The soil included sandy clayey silt, fine to medium sand, silty fine sand, and fine sandy silt. Occasional wood fragments and organics were encountered in the boring. The soil generally ranged from very loose to loose and soft to stiff. Groundwater was encountered at a depth of 12 ft BGS at the time of drilling on October 2, 2006. Groundwater levels often need to stabilize after dnlling and the water level at the tirne of drilling is probably not as accurate as subsequent measurements. Three groundwater level readings were obtained between December 15, 2006 and January 18, 2007 and ranged from 5.5 to 6.6 ft BGS. The October reading could be due to a relatively low groundwater level following a relatively dry summer and early fall, or it could represent a groundwater level that had not fully stabilized at the time of the groundwater reading. November was an unusually wet month with significantly above normal precipitation. December and January represent relatively typical wet winter months. The groundwater readings taken in December, 2006 and January, 2007 probably represent relatively typical winter groundwater levels at this location. Groundwater levels can be expected to fluctuate according to the seasonal level of precipitation, the influence of the degree of surface water runoff and infiltration, and other factors. The. groundwater Ievels recorded at Piezometer P-17 are summarized in the table below. Piezometer P-17 can be added to the network of piezometers (Piezometers P-1 through P-16) in the North Edmonds area that are monitored by the City.

A boring with a groundwater monitoring well . was installed as a.part of that study and was located an estimated 150 to 2.00 ft north of Piezometer P-17 along the present alignment of 73 d Place West. The groundwater was measured at a depth of 12.5 11 BGS at that location on March 15, 1989.

This seepage condition results in areas of standing and flowing water and vet surficial soil conditions on Lot 2 and adjacent areas above (to the east of) 73'd Place West. A significant portion of the seepage appears to be flowing across the ground surface and is being collected in an informal manner along the east edge of the 73`d Place West pavement and discharged into a catch basin. An unknown amount of this groundwater seepage infiltrates back into the ground as it travels between its point of emergence as a spring on or near the base of the bluff and its present collection point at the edge of the road. It is desirable to intercept this seepage further upslope. This will both limit the amount of infiltration back into the landslide mass, as well as improve the surficial, wet conditions on Lot 2 and adjacent areas. However, damage to the existing Drainage System IA and the difficulty in replacing and maintaining such a system with City maintenance personnel is problernatic. We understand that the owner of Lot 2 is considering the installation and maintenance of surface drainage provisions that would intercept the groundwater seepage and the related surface water flow and convey it to the City's storm drain system. This approach has several advantages. The seepage collection system can be designed by the property owner to facilitate future development of Lot 2. Maintenance of such a system occurring on private property is best accomplished by the property owner. In addition to the benefits to Lot 2, such a system would reduce the amount of surface water infiltration back into the landslide mass and thus provide an effective replacement for the function of Drainage System IA. Landau Associates previously considered drainage improvements in this portion of the Lorian Woods subdivision to replace the general function of the City -installed drainage system that was located near the base of the bluff and that has repeatedly been damaged by upslope landslides. One approach considered was to install a subsurface groundwater drainage trench along the easterly edge of 73'd Place West to intercept suspected shallow groundwater flow. Given the typically wet surficial soil conditions on Lot 2 and adjacent areas, it was thought that the groundwater level may be very shallow at the location of the street and there could be benefits from the installation of a subsurface drainage trench (such as a gravel -filled trench with a perforated pipe that would drain to the downhill catch basin). The depth of any subsurface drainage system would be limited by the elevation of the downstream catch basin manholes (i.e., to allow a gravity drainage system). However, information on the actual depth of groundwater at this location was not available until the installation of the piezometer under this current study. The available information suggests that the winter groundwater level is presently on the order of 6 R BGS at the piezometer location. The groundwater level could fluctuate and we recommend that the City continue with groundwater depth measurements at Piezometer P-17 in order to assess longer -term U11241B7 4Edmdataipnoinear.W74%1151021AWIPlRVPiczctlstannWL,tm.d,c a DRAFT '12/j7/2007 15:22 PAX 425 7781W9 HANSEN MCLAUGHLIN • 007 conditions. Given the limitations on the probable depth of any subsurface drainage system along 73'd Place West, to allow gravity drainage and the current depth of the groundwater, it appears that a subsurface drainage system along 73Id Place West may be of limited benefit. In our opinion, greater benefit would be achieved by allowing the owner of Lot 2 to install and maintain improved surface water interception provisions on Lot 2 and adjacent common areas of the Lorian Woods Subdivision and conveying the collected water to the City storm drain system. We suggest monitoring the groundwater level in PieiometerP-17 before and after any drainage improvements upslope and then reassess whether drainage improvements in the street are warranted. We appreciate this opportunity to be of services to the City on this project. Please call if you have any questions regarding this technical memorandum or if we can be of further assistance.

Landau ,is providing geotechnical oversight services .of developments for the City of Edmonds. The Landau letter also discusses construction 'practices on Lot.3 of Lorian _ "Woods;: the .Bosch:House. There is a `concern expressed that temporary, soil stockpiles are to . close to the 'top. of the. slope and that. there .could be .further , slope, failures in the near future. Rainfall -'was described b`y Landau as being above.:average."for the preceding months and heavy ' ' for the day preceding_ the slide. Sept J6, 2003: A slide.occurred on Lot.4 of.Sequoia Ridge' -that reportedly impacted Lot. 2 of-;Lorian Woods and/or the native growth area 'adjaeent to Lot 2 of L'orian,Woods. This is discussed in a letter by . . .: '.Landau dated September 16, 2603. The weather,prior to the slide is described'as being:dry.

Project No T-840-10 'Page No. 2 ' riar;and Cindy Isaacson June 2; 2009. ; • From the discussion above, it appears that there' has "been: an increase in slide 'activity subsequent" to the development of the land above.Lots 1, 2, and 5,of Lorian.Woods. This can either be attributed to.disturbance. from the development activity or perhaps to. increased observations of the slope as a result. of the' development activities. In any -event, none of the direct deposits of.landslide debris have been observed nor reported_to have :.. directly impacted the envelope of the proposed Isaacson. House., To mitigate potential impacts ;due to the recent increase in' slope movements, a catchment •wall, will_ be placed above the proposed Isaacson residence to control materials that may encroach'on the house envelope in the future. Increased stewardship of the slope area can•be. expected to occur as homeowners, perform -maintenance work to preserve property values and the safety.of their. respective homes.. j In,..our report for the plat -dated 1989, we state that itis,,ouropinion that the return period for the, shallow slides described above to be on the order -of 10 to 20 years. In addition, our report discusses -that the shallow avalanches and.de'bris flows do not commonly reach the lower area where the house is to be located. Sloae`Cross Section Using survey information provided .by Western Engineers and -soil test borings from our files 'by :others; we developed. the attached cross section. The., schematic. location of the cross section is shown on Figure 3..: •The . generalized geologic section is shown on Figure 4. This ,geologic section is consistent with the sections drawn by others forthis vicinity.: The logs for the borings used to construct the cross section are.presented in Appendix"A. Appendix B is the survey ;information from Western _Engineers showing: the. surveyed location of the section Cedar Loy, Accumulated S1ok Sediments and General Slope Restoration �- v he house site 2 we -recommended that the cedar to located above t o report dated March 31 008 In our referenced p ,. g . . _ in the common area be removed: This log.has a diameter of. about three feet and�has been lodged on the slope for . many years. Prior to, 2006, it does not appear that there was any significant sediment accumulation above the log.: Some of the slide debris fr6iri the-2006 even(,hasaccut.nulated behind- uphill -of the log., : We have estimated that the amount; of soil that needs fo be removed is-�on the order of 30;'cubic yards: The soil. should 66"removed using a low.impact technique., It does not appear to feasible io use�a•trackhoe to remove theI. soil1. and the -log. -We recommend- that the contractor use a, vacuum truck to remove the soils.. This will limit the: number of Yorkers- required,- to. climb up the slope, and will .speed the "removal of the soil. -The soils should be removed io.*restore the , slope profile• i ' the, area of the log..The, exposed log can then be cut, into smaller'pieces 'and be removed: The in. situ stumps that have been supporting the log should remain intact on the slope -and, should 'not be physically. removed: A preconstruction meeting should-be"held to discuss the contractor's final plans. The slope above the. proposed house should be ,cleared of .all loose tree debris, logs, and dislodged stumps. The: ; woody material can be chipped on=site and, be reused as mulch for erosion control. In situ stumps should not be, removed unless approved for removal by the geotechnical engineer. There is, a short steep area immediately . adjacent to the eastern upper property corner that should be regraded to match adjacent slopes.:This short: steep area was created, through the removal of a stump during previous clearing activities. 'It is estimated that:five cubic yards of soil may need to be removed toreshape this local area., The excavated materials should be exported form the site unless it is suitable for reuse as structural fill and will_'fit in the stockpile area shown onthe current project plans. Project No T-84040 Page No.•3 , Brian,and Cindy Isaacson `-June 2'• 2009 .. '. All work •onthe slope should be done..under the full-time observation. of a`representative of the Geotechnical Engineer. = Catchment Wall Revisions In our 2008 report, we, presented design criteria for' a catchment wiidlf constructed with soldier: piles: Due: to the' projected costs of the soldier pile wall-, the project plans now show a.cantilever retaining wall designed using the same catchment wail'.and`retaining'wall foundation criteria.contained in our report. The wall"does not. have an ;access path as -shown on.previous drawings'..When sediments accumulate behind the, wall; they willneed.to be;, removed by hand using.a'wheel barrow or,through the use .of a vacuum truck.... . In addition to the catchment wall, the final house plans include concrete walls that are designed as retaining walls that extend to three feet above grade along the eastern uphill side of the house. In addition, no door openings:' were placed along the uphill side of the house. Groundwater Level Mdnitorin - " We have reviewed static water level measurements' collect ed by. Landau and by, the City of. Edmonds for - piezometer No. 17. This piezonieter is located near the southwest corner of the lot...: The Piezometer installation :•.is ,discussed. in the Landau memo dated, January 24; 2007. :The,depths are shown on the, memos. attached in A Pen dix,,C. The data`is. summarized'on Chart 1 in Appendix C., The data shows that the. static water level rises PP . P.. . . C in the wetter•winter months And declines in the dryer summer months. The proposed project should not cause. _ i t groundwater levels to rise on of adjacent to the lot: ; We understand that the City of Edmonds will continue to monitor thestatic water level on a regular basis.: . ern lA a e rain Sst w k n res onsibilit fo r the maintenance of Draina e S s tern 1 A.

This is `shown in the photo 'attached `as Figure 1, Clearing activities ,associated with a previous �permit:for Lot 2 of Loiian Woods appear. to`have'�remo."ved SDMH:5 _and SDMH 7. On: April 9,. 2009, we .opened -the lid on SDMH 6 and -observed',' flow entering the structure from the.-8 inch . CMP that extended up to: SDMH $. There was a light trickle. of water froni the line that extended from SDMH 7 towards SDMH •6: It. appears that., SDMH 7 has been removed during previous clearing.., activities:, . We recommend that SDMH 6 be removed and be backfilled with a clean crushed rock. A slot trench should be . .. provided to allow any, seepage that. may,continue from .upper .trench lines to reach the footing drain of. the catchment wall: Project No -T-840-10 Page No. 4 Brian and Cindy Isaacson . June 2; 2009 During site grading, the. remaining pipe that drains SDMH 6 to SDMH 5 should be removed'and the trench be backfilled ,with structural fill. The. discharge •from SDMH 9, and the actual condition of SDMH .5. should be evaluatedduring: site grading. The: lateral system.to SDMH. 9 is above -grade for'most of its extent:'.,If the :evaluation" indicates •that the line should remain in place,'the pipe should. be replaced with HDPE.,butt welded pipe:. The diameter of the HDPE pipe does not need to be any larger than, four inches and may be placed on the surface in'a manner consistent with the upper drains being placed fof this project: The CMP between the location of SDMH 5 and CB #D,should,be exposed and be replaced'with a 12=inch PVC pipe to connect 11 with the lateral to-SDMH 9:. To, facilitate maintenance, .either, anew catch"basin. can be installed at the location:of SD,MH.5 oi;a cleanout:can be installed at the.elbow.that would replace SDMH 5:. -The :drains shownon Sheet. 4 of 6 of-, the plans prepared- by Western Engineering are' intended to replace the. formei system that was placed by- the city in the late 1080s.• The use .of flexible pipe on the surface and surface collection: pans should, facilitate maintenance:. Any damage to the system will be visible and -repairs can'then be made without the need for equipment.or trenches on the hillside: ; Sl6m Revegetation• Plans` The slope revegetation plans should proceed as soon -as possible following the removal of 'the cedar. log ;and slope restoration' work and placement. of.the drainage system described above. ' Fills drainage . These fills 'are u to promote the ho se Fills of 'u ' to two, feet will. be required in local areas around. g • P minimal in. -nature and will not decrease the',stability of the -site or adjacent, slopes: There will need to be a fill of UP. to five feet in, depth to create the landing for: the entryway stairs and a'frll of up to four feet in depth for the northwestern -edge of the, patio. along-the'back of,the house:, As shown': on_the'civil;plans, the cut.for'the house involves the removal of 450•yards'•of soil "and the placement of 50 cubic.yards-of,soil. Thus, thereis_a net-loss.of soil from the site of about 400. cubic yards. The proposed fills.. are' not in a location that .will create• slope instability issues. The short 2:1 •fill slope along the north elevation.of the .house from .the ,fill used to support the' northwestern corner; of the- patio is suitable.,for this site and will not:lead to slope instability issues. To address the possible 'settlements from the •fills used ,to create the- entryway stair's,. we recommend: that the' area be preloaded prior to, placement of the stairs arid,associated walls. The preload may Consist of Ecology -Blocks 'stacked-two.blocks:high- covering the -footprint of the.proposed,fril-. ..As an alternative, a.,tempora'ry stockpile .of backfill At least six feet high can be. placed at. the -entry fill location. This. -preload should, remain .in place for at, least four weeks prior to placernent.of the walls and fills needed to support the lower portion_ of the entryway stairs: A temporary fill stockpile area adjacent to the southwest corner -of the lot is permissible-.7his is below the toe of P Y P adjacent P , the eastem,slope'and,well.away from the slope that is present on the western margin of the plat ofLorian Woods. It -is our opinion that the use of the area for a temporary stockpile no(to exceed 50 cubic yards will not"decrease the stability of the'site slopes on or, adjacent. to, Lot 2: Unless approved by the geotechnical engineer, the stockpiled soils must be completely removed .the beginning of the season on October.1. : Y Y _ g g P. - . , Project No T-840-10 .

Plans prepared for Brian Isaacson by Western Engineers, dated April 15, 2007 and April 17, 2007 Dear Mr. and Mrs. Isaacson: In accordance with your request, Terra Associates, Inc. is providing on going consultation services to you regarding Lot 2 of Lorian Woods. We previously prepared the referenced report for the entire plat, the referenced report for your parcel, and the referenced letter regarding Tree Removal for you parcel and adjacent areas. We have also reviewed the plans prepared by Western Engineers. Our review of the plans by Western Engineers has included conversations with Mr. Barry Constant as well as several site visits. 12525 Willows Road, Suite.101, Kirkland, Washington 98034 Phone (425) 821-7777 • FaX 14751 R?1-4-A14 Brian and Cindy Isaacson April 25, 2007 Terra Associates, Inc. has made observations on the slope above your lot on several 'occasions since 1989. We have observed that the drainage system installed by the City of Edmonds has been damaged by heavy erosion and that the seepage pattern has changed over the years. We understand that you will be assuming maintenance responsibility for the drainage system on and uphill of your house. In the past, the City of Edmonds performed the maintenance. A modified drainage plan was prepared by the city using lined surface swales however, the revised system was never built. The purpose of the drainage system is to collect groundwater that has seeped out at the surface in a series of springs. The intent of the system is to collect the seepage .and tightline it to appropriate discharge points. This will reduce the potential for the seepage from re -infiltrating the site soils. The plans prepared by Western Engineers reflect the need for the drainage system to remain flexible to allow for changes in the seepage rates and locations. As with any drainage system, regular maintenance will be required. We recommend that the high density polyethylene (HDPE) pipes used on the slope not be buried. This will allow for expedited visual inspection of the collector system and allow for timely repairs. All pipe used on this project must have smooth inner walls. The HDPE pipes should be provided with heat welded joints. The pipes should be placed to descend as close to the fall line as possible. The collector devices shown on the plans will require trash racks and regular maintenance to keep the collectors free of debris and sediment. The maintenance schedule will need to be monthly or following each heavy rain storm. Dense impenetrable brush such as Himalaya blackberries should not be allowed to grow in the area of the collector system. The surface collection drains shown on Section AA and BB should be lined with an HDPE liner at least 20 mils in thickness. Any joints in the liner will need to be made with the adhesive that is compatible with the HDPE and in accordance with the supplier's recommendations. All elements of the drainage system will need.to be maintained. Damage area will need to be either repaired and/or replaced in a timely manner. In addition to the drains shown on the slope a drainage swale will be constructed along the top of the retaining wall that is proposed immediately east of the proposed house. This proposed retaining wall will be provided with several feet of free board on the uphill side of the wall to serve as a collection point for soils eroded off of the slopes above the house over time. A pathway suitable for the transit of a small skid steer loader will need to be maintained .to allow removal of any accumulated sediments over time. The perimeter ' of the house will need to be provided with both footing drains and a tightline to collect downspouts. The downspouts should not be tied into the perimeter footing drainage system. The footing drains and downspout tightline should be tightlined separately away from the house a distance of at least ten feet and a vertical fall 'of at least one -foot before being joined into the final tightline to the plat storm drain system. All subdrains and subsurface drainage pipes will need to be provided with cleanouts. Cleanouts will need to be serviced on an annual basis. This may consist of advancing a TV along the pipe to verify the pipe is open and free of blockages or damage. Any blockages or damage must be repaired in a timely manner. Regular maintenance and on going stewardship will be required to maintain the slope area on and above your lot. Project No T-840-10 'n--.

Project No T-840-10 D--- AT- Z Brian and Cindy Isaacson May 21, 2008 The u ose . p rp of this s letter is -t.o address the draina a (elements of the proposed new, house on Lot 2. Our report / dated March 30, 2008; contains our recommendations, for the'. design and construction of the' proposed house. As -discussed in :our, report, the -design of the house cannot fully mitigate .the risks of encroaching landslide .debris. from above.the'house.' For`this reason,'the d'evelopmerit'plans include a catchment wall- above. the'house. The purpose,of,this wall is to. contain the. local soughing, calving'and erosion that is ezpected.to,occur from the.' headwall above the lot. We understand that, at this time,. you want to proceed with the initial installation of the -drainage improvements and startwith the'vegetation replacement plan. Last summer, you had a contractor remove selected trees. on the. `slope above and on your lot. One logthat'has.acted,as a'soil catchment-facility;remains on the slope above`your ..proposed house. We have recommended that the log and the soils'hehind the log be -removed prior to establishing the new vegetation on the slope and the, construction of your house:-.The'elements of the referenced drainage plan prepared, by Western Engineers that will be installed at this time are. the upper seepage collection drains and the. . lower tight line storm.drains along the northern and southern property -lines. These drains can,be installed prior .. to the construction of the house and upper catchment wall. The. house and wall drains -will then be routed into the . system once the house is built.; v Terra' Associates, Inc. has made observations on the slope' above,your lot on,'several occasions since .1989. 'We :have observed that ' the drainage system installed by the City Hof Edmonds in,.the 1980s. has been damaged, by :. heavy erosion and that the seepage pattern has changed over the years: We understand that you will be assuming maintenance responsibility for, the drainage system on andf uphill 'of your lot., In the past, the,City of Edmonds performed the maintenance. , The referenced plans prepared by ,Western Engineers~reflect the need for the drainage system to remain flexible to allow, for, possible changes in the seepage rates and locations. As :with any drainage system- regular maintenance .will -be required.- The high density, polyethylene (HDPE) pipes used- on the slope will not be buried. ' This. will, allow for rapid visual inspection of the collector system -and allow for timely repairs. All. pipes used on this project "must have..smooth inner walls. The `HDPE pipes should be provided with heat,welded joints. The pipes, should be. placed to descend as close to. the fall`line as.possible. The upper end of the collection pipes should be' anchored as showri 'on Figure T attached to this letter.. The -fence . -posts •shown on'Fi' gure.1 will be suitable for" maintaining alignment of the pipe below the intakes. In the event seepage patterns change overtime, either new pipes of inlets :will need to be.insialled or the existing pipes and inlets will need to be shifted to collect the new seepage zones. The collector devices shown on the plans will require trash racks and regular maintenance to keep the collectors free of debris and sediment. The -maintenance. schedule will need •to -be monthly or -following each heavy rain storm: Dense impenetrable brush such as Himalaya blackberries should not be allowed to grow in the area of the' collector system. The collection pipes should consist of 4-'inch diameter HDPE'pipes connected to collection ' cat ch basins 'that' t at consist 'of HDPE: Th e i es should be manifolded tothe catc' h_basinsabove grade _ P p ' to allow direct observation of the conne.ction ov er time. , The toll ector.catch-basins should be provided with removable lids to allow direct observatioris'irito the -interior of,the'catch basins aiid,to allow maintenance to occur.

Stettler, P.E. DATE: August 20, 2007 RE: COMPLETENESS REVIEW FOR STSREEINFLUME HAZARD AREA SUBMITTAL PACKAGE — PLAN REVIEW NOS. BLD2007-0833, BLD2007-0834 ISAACSON GRADING AND DRAINAGE —16007 73RD PLACE WEST EDMONDS, WASHINGTON This technical memorandum provides our assessment of the completeness of the geotechnical portions of the permit package for Grading and Drainage submitted to the City of Edmonds for the proposed referenced development within the Earth Subsidence and Landslide Hazard Area (ESLHA) of North Edmonds. This completeness review was accomplished in accordance with Landau Associates' On -Call Geotechnical Engineering Services Agreement with the City of Edmonds. The completeness review is not intended to be a thorough review of the submittal package. Instead, it is intended to be a cursory review to assess whether the submittal appears to contain the necessary information in order to complete a geotechnical peer review in accordance with Edmonds Community Development Code Chapter ECDC 19.10. The submittal package provided to us included: • An Erosion and Sediment Control Plan, an Existing Condition and Tree Plan, and a Drainage Plan. All three plan sheets were prepared by Western Engineers, Inc. and printed June 18, 2007. • A copy of the City of Edmonds Plan Review Corrections form for the project prepared by Jeannine Graf of the Building Department, dated August 15, 2007. On the basis of our cursory review, it appears that the submittal package is missing a number of items that are required for Building Department submittals for projects within the North Edmonds Earth Subsidence and Landslide Hazard Area. ECDC 19.10, and by reference ECDC 23.80, identify a number of specific submittal requirements. We are aware that this property was previously the subject of a tree clearing permit through the Planning Department. Although certain documents were provided as a part of that previous permit application, the current application for grading and drainage through the Building Department is a separate application and needs to be a complete submittal package. The applicant is referred to ECDC 19.10 and ECDC 23.80 for a complete outline of the required plan review submittal materials. The key missing elements are outlined in the Plan Review Corrections form prepared by the City of Edmonds for this submittal. In later peer review for this project, we will be 130 2nd Avenue South • Edmonds, WA 98020 • (425) 778-0907 • fax (425) 778-6409 • www.landauinc.com looking at the required geotechnical report to see that it addresses the slope stability and related site development issues that are identified in ECDC 19.10 and ECDC 23.80. On the Erosion and Sediment Control Plan is a note that states "Proposed grading based on existing site features. Base survey not accurate with current conditions." It is not known what is meant by that statement. The applicant is required to furnish a topographic map showing current conditions and contour lines on at least two foot intervals. If the existing base map does not accurately show the current conditions, then the base map should be redone prior to resubmittal. Proposed drainage features are shown on the Drainage Plan. Other features are shown without sufficient detail. For example, the Drainage Plan also shows a proposed footprint for a house, garage, retaining wall, along with what appears to be drains and drain pipes around the proposed house and garage. We assume that these features are not a part of the current permit submittal, since there are no details provided on these features. It should be made very clear what elements of the proposed plans are included in the current grading and drainage permit application and which are not. It would be appropriate to point out to the applicant that providing an application for only limited grading and drainage at this time, but not other elements of the planned property development, presents certain risks to the applicant. Review of development plans are benefited when the reviewer has a complete understanding of the overall development. This is particularly critical in the Earth Subsidence and Landslide Hazard Area where an appreciation of the planned overall site grading, retaining walls, foundations, and drainage is an integral part of understanding whether the proposed overall site improvements appropriately benefit or detract from long-term slope stability. Reviews that are conducted on a piecemeal basis run the risk that subsequent permit applications for the proposed additional grading, drainage, retaining walls, and structures that will be a part of the overall property development may disclose issues that would require rework of the drainage features that are a part of the current application. Please contact us if you have any questions regarding this completeness review and when you are ready for us to commence with our geotechnical peer review.

JUN 04 20-98 BU m-ME]Vr The City recently sent a review package to our client that requested a letter with specific language_ as a release of liability to the City of Edmonds. The design team for this project is: Western Engineer, Inc; Barry R. Constant, P.E.; Project Manager, Civil Engineer Terra Associates; Chuck Lie, Geotechnical Engineer Reed and Associates, Inc.; Wendel Reed, Structural Engineer Landscape Architect; Jennifer Lee, Licensed Professional As the lead design Professional Engineer providing services to our client, Mr. & Mrs. Brian Isaacson, my team and I have reviewed the geotechnical report and understand it's recommendations and have incorporated these design recommendations into the site civil design of this project. The design parameters that my team and I have designed for the civil drawings are using industry standard design measures to reduce the potential risk of injury or damage from any earth movement predicted in the report. Although the recommendations in the geotechnical report will have been followed during the construction on this site, this engineer does not guarantee the long-term maintenance of these items. These maintenance items are under the control of the client and not under direct supervision by myself. Maintenance will be required as long as there are no installed permanent solutions to the landslide hazard area. And further: in my judgment, the plans and specifications prepared by the structural engineer conform to the recommendations in the geotechnical report. LAND USE CONSULTANTS • CIVIL ENGINEERS • LAND SURVEYORS • ENGINEERING CORPORATION That the risk of damage to the proposed development, or to adjacent properties, from soil inctahility will ha minimi7M enhiact to tha onntlitinm cPt forth in the rPnort and that tha proposed development will not increase the potential for soil movement. Minimized shall mean that the applicant has utilized best available science and commonly accepted engineering and architectural practice to minimize, to the extent possible, the risks associated with development of the property. The risk of onsite soil movement in the building site area probability within the next 25- years is approximately 12 percent. This is based on long-term study by our team geotechnical engineer (Mr. Chuck Lie:) who personally has studied this landslide hazard area for 20-years. By studying the various geotechnical reports issued for the site over the last 20-years and using common and standard engineering practices for the erosion and sedimentation control, as well as the long term drainage solutions engineered and incorporated into the site will minimize land movement activities. Please see letter from the landscape architect for additional information The upper catchment wall, as designed by Reed and Associates, Inc. with assistance from Chuck Lie has been designed to stop low velocity landslide activated soils from contacting the house structure. An onsite deep boring was advanced in the area of the proposed wall. This wall has three feet of exposed wall above a very deep soldier pile support structure. The site is designed to allow a small, lightweight powered or unpowered wheeled container to remove any soil spoils from the upper wall area and transport them down slope safely. This type of maintenance is not guaranteed by this letter. Please see letter from the landscape architect for additional information The Landscape Architect will provide deep-rooted planting that remove water from the loose upper soils on site. The landscaping will also provide small trees to provide the same function. Please see letter from the landscape architect for additional information The Landau Geotechnical report, dated 2007, identified certain areas as landslide hazards for this site and certain recommendations to reduce and minimize these hazards. Western Engineers in conjunction with Terra Associates have reviewed, designed and approved the site engineering for the house structure location and elevations, retaining walls and catchment wall above the retaining walls. We have reviewed all structural and retaining wall footing drains and provided an extensive underground drainage conveyance system capable of removing and directing any runoff away from the house structure and retaining walls, down slope directly into the City drainage system on the roadway below the new house. Reducing and removing storm water runoff from the soils onsite is the number one risk reduction factor associated with earth movement. No one has control over the potential for shallow or deep-seated earthquake induced land movement hit we have redined the nhility of the land to move on nre.q.viri7.ed (water pressure) underground soils, which could enhance additional land movement. The attached soil boring water levels and the attached information regarding the piezometer reading all indicate that the existing ground water levels has been reduced over time.

SURVEYORS • PLANNERS • ENGINEERS March 12, 2007 City of Edmonds 121 — 5`I' Avenue North, 2nd Floor Edmonds, WA 98020 425-771-0220 Subject: Isaacson Drainage Plan, Lorian Woods, Edmonds Dear Mr. Fiene: OCT 111007 PERMIT COUNTER Recently we attended meetings with the City staff to discuss the building permits and drainage plan for Mr. & Mrs. Isaacson's building lot in Lorian Woods, Edmonds. We are submitting this letter report for the drainage portion of the site plan for review, along with engineering drawings. Since this lot is an established, legal lot, we are providing this letter report to quantify the plans for the drainage system. Also see the TESC and grading plans in the attached drawing set. I performed a site visit to ascertain the viability of the existing drainage system on the hillside. This system was installed under the LID 210 (1984) for the City and for general utility improvements in the area. During a small landslide event (12-16-2007 and others more recent, dates not available) portions of this drainage system were damaged. During the site visit, I determined that some of the existing system is still functioning and would work for the proposed house on Lot 2. Please refer to the drawing set for drainage structure information. The current system that appears to function is CB's number 88, 89, 91, 92 and 93. Catch Basins numbers 94 and 95 were displaced during the landslide events. The French drains that were part of these.catch basins (CB 94 & 95) appear to be missing as well. We plan to use the remaining Catch Basins as drainage collection points for our proposed surface drainage system. Please refer to the Landau Report, dated July 25, 2002 for surface drainage recommendations. The site visit I conducted on March 7, 2007 results in the following observations. The French Drain and CB # 92 appear to be intact and functioning as designed. Flows were minimal, but there was water flowing through the system. This portion of the system will remain undisturbed. Some flows were entering CB # 93 but I believe that the flows were just `accidental' in nature. To clarify, this CB is in an area that some surface runoff just naturally slopes into. E: / 2006 / 06792 / Engineering / Drainage Letter 3-12-2007.doc LAND USE CONSULTANTS • CIVIL ENGINEERS • LAND SURVEYORS • ENGINEERING CORPORATION As shown on my sketch (attached below), there were 5 drainage flows that I discovered on the hillside. Three `major' flows were continual hillside seeps from the sandy layer that has been the water source since this area was first researched. These are labeled as 1, 2 and 3 and are located to the north side of the project. Two `minor' hillside surface flows appeared to originate from the top of the Sequoia Ridge area, well above the seep zone. These are labeled as 4 and 5 and are located near the middle portion of the project. Further research, up the hillside, may be necessary to determine the actual location of the source of these flows. Our overall plan is to install a new catch basin system located at the northeast corner of Lot 2, adjacent to the proposed retaining walls north end. This will allow the connection of the piping.from the 3 major seeps to flow directly into a structure. It will also allow a French drain to be installed on the uphill side of the landslide retaining wall. The 2 minor surface flows will be directed into the nearest catch basins via surface piping. The drainage plan is a `design / build' plan that will be constructed on the hillside after the landslide rubble has been cleared and the remaining danger trees have been removed. It is difficult to design a drainage system with a couple of tons of debris and/or trees in the way and where the site grading may change along with the source of surface runoff. The real key to reduce the possibility of future landslides is to reduce and remove the source of water on the hillside (Landau, 2002). To totally remove all surface water is impossible, but we can reduce the hillside seeps and surface flows as much as possible. We propose two methods to collect surface runoff. One is the Landau method of surface channels and the second is adjustable surface collectors with piping directly to catch basins. The Landau Report, dated July 25, 2002, recommended that all surface drainage should be captured and directed down slope, essentially lowering the groundwater levels and thence the hydrostatic pressure on the underlying landslide debris. The use of surface channels with impervious membrane and Articulated Concrete Pavers on top of the channels (see attached Landau design Figure 8) would direct these flows into CB's and then down slope to the street conveyance. Western Engineers, Inc. researched the articulated pavers and they do not exist in a form small enough so that the homeowner could ever move theirs. In their present form (each block is approximately 9" X 9" X 6" thick), the articulated block sheets (sheet size approximately 10' X 20') would need a large crane to position these on a surface channel. I propose to use 1-inch washed crushed rock as channel liner, instead of the pavers; this rock size can be shoveled into small buckets and easily moved when the homeowner performs maintenance on these surface channels. There's also the problem of how the hillside seeps and surface runoff gets into these channels without re -charging the underground landslide debris (see drawings on channel construction). The surface channels should be located as to collect as much rainfall surface runoff as possible in the upper areas of the slope (where steep becomes steeper), E: / 2006 / 06792 / Engineering / Drainage Letter 3-12-2007.doc f just below the seep elevation (see drawings). These channels can then be directed into the existing and/or proposed catch basins per the design drawings. It should also be mentioned that at the top of Sequoia Ridge area, all surface runoff should be re -directed to flow down the backside of the ridge where there is essentially minimal development, less steep slopes and more surface vegetation. This action alone will reduce / remove the 2 secondary minor runoff flows from this area. The surface piping shall be thin walled 2-1/2 inch diameter HDPE (or similar flexible hosing), butt -welded to form long, movable piping in order to adjust and re -adjust the inlet to the best location to capture the flows. The hillside seeps and upper ridge drainage can be captured by a `scoop' type device (aluminum weldment, see drainage plans) that will direct the main flows into the individual pipes. These scoops will have anchor tabs to use a rebar or similar spike device to anchor the scoops in place. With individual scoops it will be easier to capture these individual flows directly at the point source and still have the ability to change their location as the seeps may change location over time. The rooftop drainage for the residence is also a `design/build' situation, as we do not have the final house design in our hands. Using the preliminary design we have provided a general location of rooftop downspouts and clean -outs for the entire residence. These are tight lined directly to the new catch basins with notes on sizing and pipe slopes on the drawings. All of the above drainage will collect in the existing and proposed catch basins and routed to the west, down slope to the existing street drainage. During my site visit, there appeared to be two separate drainage systems in the exit road, adjacent to Lot 1 and 2. The proposed new catch basin located at the northeast corner of Lot 2 will be routed along the northern property line, west to the existing roadway. Another catch basin will direct the runoff just above the road into one of these two systems, an existing catch basin #88 or another new catch basin located inline with the secondary system. Homeowner maintenance and slope maintenance is another key to maintaining the drainage system on this slope. The homeowner will install and maintain replacement landscaping on the hillside. Use of landscape plantings that will require high amounts of water will ensure the roots go deep and stabilize the remaining hillside. The recommendations above are only for the LID 1 A system, as shown in the Landau Report. If you have any questions regarding this report please call me to discuss. Sincerely, Western Engineers, Inc.

BLD2007-0833 AND 2007-0834 ISAACSON WET SEASON WORK REQUEST LOT 2 AND ADJACENT COMMON AREA - LORIAN WOODS EDMONDS, WASHINGTON This technical memorandum provides our geotechnical peer.review of a request by the applicant to conduct wet season earthwork. The request for wet season work was submitted to the City of Edmonds (City) for the proposed referenced development that lies within the Earth Subsidence and Landslide Hazard Area (ESLHA) of North Edmonds. The purpose of this geotechnical peer review was to review the request for wet season work and assess its compliance with City development and permit requirements as contained in Edmonds Community Development Code (ECDC) Chapters 19.10 and 23.80. This geotechnical peer review was accomplished in accordance with Task Order No. 08-23 of Landau Associates' On -Call Geotechnical Engineering Services Agreement with the City. We have received the following information forwarded by the City for review: Proposed Grading Plan Construction Sequence, Platt Checks 2007-0833 and 2007-0834, Lorian Woorls Grading and Drainage Improvements, 16667 — 73"t Place West and Lotian Woods Conutton Area, Edmonds, Washington, letter prepared by Terra Associates, Inc., dated October 14, 2008. In addition to the materials forwarded by the City, we also, referred to documents submitted for earlier reviews as documented in our geotechnical peer review technical memorandums dated December 28, 2006 related to tree clearing and July 22, 2008 and September 8, 2008 related to proposed grading and drainage for the subject project. The .City requires that earthwork during the winter season between October I and April 30 be restricted. The purpose of this restriction is to try to limit the potential for damaging disruption to the ground surface, limit erosion and sedimentation during this period, and to accomplish the work in a season that facilitates early reestablishment of vegetation for erosion control. Any earthwork within this time period requires approval from both the Geotechnical Engineer of Record and the City Building Official. The letter from Terra Associates, Inc. outlines a proposed construction sequence, including hand sewing grass seed, installation of the northern catch basins and drainage pipes, construction of shallow 130 2nd Avenue South - Edmonds, WA 98020 - (425) 778-0907 - tax (425)_778-6409 - www.landauinc.com A swales, removal of an existing silt fence and accumulated sediment along the western margin of the site, and construction of elements of the northern drainage system. Appropriate collection of seepage and surface water is beneficial to the overall slope stability. However, the process of constructing the proposed drainage improvements on the wet slope during wet weather conditions will also result in damage to existing ground cover and vegetation. This action could potentially increase the potential for surface water infiltration, and make temporary erosion and sedimentation control more difficult. In addition, any disturbed areas cannot be effectively revegetated until the next growing season. In our opinion, the suggestion to hand sow grass seed at this time of year would be ineffective. On the balance, it is our opinion that the proposed actions could present more problems than benefits. As such, we recommend that the proposed installation of the northern drainage system and other site improvements not be allowed until after the current wet season (after April 30, and preferably later in the summer). We suggest that the applicant be allowed to do site work in the wet season only to the extent that such work would help further stabilize the existing ground surface and provide improved temporary erosion and sedimentation control. Examples of limited site work that could be considered would be placement of mulch or erosion control materials in areas that currently have sparse vegetation and could be subject to further erosion and sedimentation during the wet season, and improvement to the existing silt fence or other temporary erosion and sedimentation facilities (including removal of accumulated sediment as appropriate) along the western margin of the site. Other site activities that would disturb the existing ground surface should be deferred until after the wet season. This technical memorandum has been prepared for the exclusive use by the City of Edmonds in evaluating the adequacy of permit submittal documents related to proposed implementation of portions of the Issacson grading and drainage pen -nit during seasonal wet weather restrictions on the subject property. The focus of this review was the geotechnical aspects of the application. The purpose of the review was to assess the adequacy of the application documents for compliance with City requirements contained in ECDC 23.80 and ECDC 19.10 and conformance with conventionally accepted geotechnical engineering practices. This geotechnical peer review by Landau Associates does not lessen the requirements for the applicant's geotechnical consultant and other design professionals to prepare an appropriate design for the site conditions.. We appreciate this opportunity to be of service to the City. Please contact us if you have any questions or if we may be of further service.

Geotechnical Plan Review; Drainage Plan Review, Project No. T-840-10, dated May 22-2008 Dear Ms. Bullis: This letter describes the current planned activities that will occur under the current permit application for the proposed Isaacson house. With the end of the growing season and the onset of the wet weather moratorium for site work, we have recommended deferring the following elements of the plan: 1. Placement of the southern elements of the drainage improvements. The southern drainage system will need to be modified to fit the revised catchment wall recommended by the City of Edmonds. 2. Minor grading/debris removal proposed above the house footprint to remove the accumulated erosion sediments. 3. Replanting of the hillside. 12525 Willows Road, Suite 101, Kirkland, Washington 98034 Phone (425) 821-7777 • Fax (425) 821-4334 Ms. Ann Bullis October 14, 2008 The work will be deferred until next spring when the next growing season begins and prior to the construction.of the proposed catchment wall. We recommend that the northern storm drainage system shown on the current plans be established. We are proposing a phased approach. The purpose of this work is to create an on -site discharge point for the seepage that is occurring on the site. This work will consist of placement of catch basins labeled DB-1 and DB-2 along the northern margin of their building envelope. Placement of these catch basins will not interfere with the construction of the proposed house or catchment wall. Placement of the catch basins on -site will reduce the amount of seepage that is currently flowing down the eastern edge of the road. The existing swales that were constructed last fall will be modified by hand excavations or using a mini.excavator to direct surface runoff and flows to the new catch basins. Any swales needed east of the proposed catchment wall will be hand excavated. New swales will be no deeper than 18 inches below existing site grades. If weather conditions permit, following or during the installation of the stonn drainage system described above, the northern seepage collection pans and tightlines on the slope will be installed as shown on the plans and described in our report dated May 22, 2008. The bulk of the seepage has been noted as being on the slope above the northeast corner of the building footprint. Due to the end of the growing season, it will likely not be possible to reestablish vegetation in areas disturbed by the placement of the upper seepage collection zone. The contractor will place jute matting or equivalent erosion control mats in areas where the foot traffic damages vegetation. The current erosion control plan shown on the project plans prepared by Western Engineers will be implemented. Temporary erosion control measures that were established last fall following removal of the trees under a separate permit will be modified to comply with the plans by Western Engineers. In summary, it is planned to: 1. Arrange a pre -construction meeting with the City of Edmonds. 2. Hand sow the grass seed specified on the current plans prepared by Western Engineers. 3. Establish the northern catch basins labeled DB-1 and DB-2. Soils excavated from these trenches that is not used as backfill will be removed from the site. Structural fill within the road right-of-way will ,be placed in accordance with the referenced geotechnical report. 4. Excavate shallow swales to direct the seepage and surface runoff from the northern portion of the site to the drainage basins. 5. Remove the existing silt fence and accumulated sediment along the western margin of the site,. The accumulated sediment within about five feet of the curb will be removed with a small excavator working from the paved area. The accumulated sediment will be removed from the site. No fill will be placed along the margin of the road. Any cut slopes created by the removal of the accumulated sediment will be made at a 3:1 or flatter. Disturbed areas will be mulched. Project No T-840-10 Page No. 2 e Ms. Amy BuIlls October 14, 2008 6. If weather permits, install the northern elements of the seepage collection system. A suitable weather window .will consist of a 10 period with no significant. storms in the weather forecast. All work east, uphill of the proposed catchment wall will be done with handheld equipment. 7. Terra Associates will make weekly and storm specific site visits to observe the condition, of the erosion control facilities. Any deficiencies will- be promptly brought to the attention of the lsaacson's, their contractor, and the City of Edmonds. Field memos will be submitted to the city on a weekly basis. 8. Terra Associates will make daily field visits during all work involving excavations on -site associated with this letter. We trust this letter is adequate for your current needs.

Monitoring Program, The mitigation plan shall include a program for monitoring construction and for assessing a completed project. A protocol shall be included outlining the schedule for site monitoring (for example, monitoring shall occur in years one, three, and five after site construction), and how the monitoring data will be evaluated to determine if the performance standards are being met. A monitoring report shall be submitted as needed to document milestones, successes, problems, and contingency actions of the compensation project. The compensation project shall be monitored for a period necessary to establish that performance standards have been met, but not for a period less than three years. Requirements for monitoring project: 1. Construction monitoring 2. Completed project assessment 3. Site monitoring schedule with monitoring reports 4. Performance standards & contingency actions S. Maintenance Project overview The goal of the planting plan is to provide native plantings with low water needs to serve as vegetative cover on the slope. This objective will be evaluated using quantifiable monitoring performance standards. The first year will serve as a baseline for the plant performance standards. Plant survival should be 90 percent the first year and 80 percent by the third year unless plant recruitment has resulted in the same or greater percent cover than was designed. Plant mortality can be mitigated by good.plan.ting technique that includes making sure that containerized stock is installed deep enough and adheres to planting details included in the plan. In addition, each plant shall receive a 2-foot diameter ring of mulch to a height of 3 inches above the existing soil surface. A 4-inch diameter ring around the base of each plant shall be kept free of mulch. Wood chips or composted mulch is acceptable. The planting pit of each shrub and tree to the drip -line must be dug completely free of invasive weeds and grasses. If white sweet clover grows in the area it should be retained because clover can contribute considerable amounts of organic matter as well as nitrogen to the soil when incorporated. 705 Second Avenue Suite 710 • Seattle WA `k1' I04 • Telephone: (20()) b24A—}j�� i) t�$1)Jy(I��1`M11N nn(_a)rwta.com •.

Construction monitoring In order to ensure proper planting techniques, quality of plant stock and adherence to the planting plan; construction observations will be made by a qualified professional. These observations will be made initially at the time of clearing and grading, again at plant delivery and installation, and once weekly or biweekly as construction is under- way. 2. Completed project assessment Upon completion of the planting project, an inspection by a qualified professional will be made to determine plan compliance. A written report or site observation summary will be submitted to the City of Edmonds describing whether proper planting techniques and planting notes have been followed. An "As Built" report section or plan sketch is to accompany the report to document that the plant quantity and overall general design layout was accomplished. This first monitoring site visit will establish sample plots for the baseline monitoring; determine the overall condition of the replanting area; examine the health and survival of the plantings; observe plant recruitment and identify weed problems. Vegetation should be sampled in the four main plots that run parallel to the site contours. Items such as plant health, species presence; and percent cover should be noted. The center and ends of the plots should be staked* and labeled in a manner that is easy to locate each year. Photo stations downhill and in front of each plot should also be marked by stakes*. (*permanent stakes from 2009 to 2012). These photos, taken from the same location each year, will document appearance, progress and changes in the vegetation. The vegetation will be assessed for species composition and percent cover. A sample will be taken in areas that have uniform vegetation and in areas where there are transitions between different community types. Data collected from this sample can be used to determine dominant species, recruitment of native species, presence of weeds, and the general health and character of the plantings. Plant species survival, health, and vigor should be visually evaluated. Invasive plant species will be identified. 3. Site monitoring schedule with monitoring reports At this time, planting is anticipated to be installed between the spring and fall of 2009. The monitoring period for the site will continue through 2012 (meeting the minimum three-year provision). Monitoring will- be conducted annually, in the fall, for the duration for the three-year period. Site observations each year will be submitted to the City of Edmonds or as needed, describing findings and recommendations should action be required. 4. Performance Standards & Contingency Actions The enhancement areas shall support at least 80% survivorship, and at least 80% coverage of the plants set forth in this plan. by the end of three years.

Reproduction of volunteer native species may be used to establish areal coverage requirements. Following each monitoring, recommendations will be made for the replacement of plant mortality to meet the survival percentages allowed and to meet a species mix consistent with that of the approved landscape plan. If plant mortality exceeds the percentages allowed, new replacement plants (based on recommendations for plant quantities, plant size and plant species) will be planted. Any replanting will be done by the contracted landscaper and should be done during the fall maintenance visit. At each maintenance visit, mulch shall be replaced around each plant. Each plant shall receive a 2-foot diameter ring of mulch to a height of 3 inches above the existing soil surface. A 4-inch diameter ring around the base of each plant shall be kept free of mulch. Wood chips or composted mulch is acceptable. 5. Maintenance Maintaining the planting area includes removing invasive species that threaten plant survival. The planting areas will be maintained in the fall (and late spring if necessary) of each year for the three-year monitoring, period. Maintenance will include the removal of competing grasses and non-native vegetation from a 2-foot diameter ring surrounding a given plant. Weeds can be maintained by removing the weed with the roots or cutting back the weed. If maintenance contractors are hired they shall not pull out numbered stakes installed for monitoring purposes. Blackberry removal is an integral part of site preparation in and around the proposed planting areas/groupings. Weeding such as this is important during the first year as rootstock of blackberries can regenerate substantially. Weeding should be done monthly in 2009 until it is clear that weeding can be less frequent. Herbaceous weeds can be pulled by hand in late spring while the soil is loose and before flowers have formed. Reseeding large disturbed areas where weeds have been removed leaving large patches of bare soil or where erosion or other activities have caused large bare areas is recommended.

The attached report presents our findings and recommendations for the geotechnical aspects of project design and construction. Our field exploration indicates the site is underlain by loose to medium dense colluvial soils, comprised of old landslide deposits. We did not observe groundwater seepage in either of the test pits excavated on -site. However, we did encounter a small amount of surface water flowing across the planned building area. In our opinion, provided the owner is willing to accept the risk associated with building in a landslide hazardous area as discussed in the referenced report, the soil and groundwater conditions are suitable for the planned development. The structure should be supported on a mat/raft foundation, consisting of a slab constructed over a grid of grade beams, bearing on the colluvial soils or on structural fills placed above these soils. This report does not repeat the discussion regarding slope stability risks on and adjacent to the site that is contained in the referenced report. The owner must accept the risks of slope instability, as discussed in the referenced report. 12525 Willows Road; Suite 101, Kirkland, Washington 98034 Phone (425) 821-7777 9 Fax (425) 821-4334 T' 1VIr.

Detailed building and development plans are currently not available. We understand that you plan on constructing the house in the western portion of the lot. We expect the structure will be a two- to three-story, wood -framed building with its main floor constructed at grade. Foundation loads should be relatively light, in the range of 2 kips per foot for bearing walls and 25 kips for isolated columns. Finish site grades are not known. Given the sloping topography, we expect site grading will consist of cuts up to six feet to establish desired drive and building floor elevations. We previously prepared a report entitled Geotechnical Report, Meadowdale Beach Lots 54 through 57, Edmonds, Washington, Project T-840-1, dated June 6, 1.989. This previous report.was written as part of the plat recording process for Lorian Woods. Lorian Woods is located within an area that has been subjected to past earth movements. The risks of earth movements are addressed in our previous report and must be accepted by the homeowner. This report does not address slope stability beyond recommendations that will retain the existing level of slope stability on the site. The recommendations contained in the following sections of this report are based on our understanding of these design features. If actual features vary or changes are made, we should review them in order to modify our recommendations, as required. We should review final design drawings and specifications to verify that our recommendations have been properly interpreted and incorporated into project design. 2.0 SCOPE OF WORK Our work was completed in accordance with our proposal, dated August 27, 2004. Accordingly, on November 8, 2004, we excavated 2 test pits to a maximum depth of 11.5 feet below existing surface grades. Using the information obtained from the subsurface exploration, we performed analyses to develop geotechnical recommendations for project design and construction. Specifically, this report addresses the following: • Soil and groundwater conditions • Site preparation and grading • Excavations • Foundations • Slab -on -grade floors • Retaining walls • Drainage t ' • • September 14, 2005 Project No. T-840-10 It should be noted that the recommendations outlined in this report regarding drainage are associated with soil strength, design earth pressures, erosion, and stability. Design and performance issues with respect to moisture as it relates to the structure environment (i.e., humidity, mildew, mold) are beyond Terra Associates' purview. A building envelope specialist or contractor should be consulted to address these issues, as needed. 3.0 SITE CONDITIONS 3.1. Surface The building site is located in the Lorian Woods development, south of North Meadowdale Road, near the 7400 block in Edmonds, Washington. The building site is located on Lot 2 and is currently unoccupied. The approximate location of the site is shown on Figure 1. The portion of the lot containing the building site slopes down to the west at grades ranging from 10 to 50 percent. Along the eastern portion of the lot and east of the building site, the site slopes up with surface grades approaching vertical in places. The site is thickly forested with mature alder, maple, cedar, and fir trees. It is our understanding several of the large diameter trees on the slope east of the building site will be removed and replaced with lower growing trees and bushes that root well in wet soils. The site is bordered with undeveloped lots to the north and south, an existing residence along the top of the slope to the east, and an asphalt driveway servicing the Lorain Woods development to the west. During our exploration, we observed surface water flowing across the building site area. The surface water was flowing from the slope located east of the building area. 3.2 Soils The soils we observed in the test pits generally consist of 12 to 24 inches of topsoil overlying colluvial soils originating from the hillside, east of the building envelope. We observed colluvium in both the test pits. The colluvial soils consisted of loose to medium dense silty sand with occasional gravel, organics, and blocks of silt. The colluvial soils observed in Test Pit TP-1 were loose and wet to approximately 8.5 feet below existing surface grades and moist below 8.5 feet. The soils in Test Pit TP-2 were loose and moist to a depth of approximately 5.5 feet, becoming wet below 5.5 feet and medium dense below 6.5 feet. We observed a large -diameter, nested tree in Test Pit TP-2 at a depth of approximately nine feet below existing surface grades. Both of the test pits were terminated in the colluvium at depths of 10.5 and 11.5 feet. The approximate test pit locations are shown on Figure 2. The Preliminary Surficial Geologic Map of the Edmonds East and Edmonds West Quadrangles, Snohomish and King Counties, Washington, by Mackey Smith, 1975, shows soils in the vicinity of the site consisting of Old landslides (Qols). The soils observed in the test pits are consistent with this classification. Page No. 2 • September 14, 2005 Project No. T-840-10 3.3 Groundwater We did not encounter groundwater seepage in any of the test pits. However, we observed mottled, wet soils in the upper portions of test pits. The conditions observed indicate that a perched water table develops at times during the wet winter season. Perched groundwater levels and flow rates will fluctuate seasonally and typically reach their highest levels during and shortly following the wet winter months (October through May). 4.0 DISCUSSION AND PRELIMINARY RECOMMENDATIONS 4.1 General As noted earlier, the site is in a mapped landslide hazard area. Relative risks of slope movement are discussed in our June 6, 1989, report. Provided the owner is willing to accept the risks associated with slope instability at the site, in our opinion, the site conditions are suitable for the proposed construction. We recommend the structure be supported on a mat/raft foundation, bearing on the existing. colluvial soils or on structural fill placed above these colluvial soils. For foundation backfill, we recommend minimizing the placement of fills on this site. A surface swale should be constructed along the uphill side of the house to prevent surface water from impacting the structure. The swale should span the entire width of the building area and discharge into the Plat storm system. The site soils contain significant amount of fines and will be difficult to compact as structural fill when too wet. The ability to use native soil from site excavations as structural fill will depend on the soil's moisture content and the prevailing weather conditions at the time of construction. If grading activities take place during the winter season, the owner should be prepared to import free -draining granular material for use as structural fill and backfill. Detailed recommendations regarding these issues and other geotechnical design considerations are provided in the following sections of this report. These recommendations should be incorporated into the fi-nal design drawings and construction specifications. 4.2 Site Preparation and Grading To prepare the site for construction, all vegetation, organic surface soils, and other deleterious materials should be stripped and removed from the building area. Organic topsoil will not be suitable for use as structural fill, but may be used for limited depths in nonstructural areas. We recommend that soils excavated from the site that are not needed for foundation backfill be exported from the site. Once clearing and stripping operations are complete, excavation can be initiated to establish desired grades. We recommend keeping all cuts for site development purposes to depths of six feet or less. Page No. 3 • • September 14, 2005 Project No. T-840-10 Following excavation, all exposed surfaces bearing should be observed by a representative of Terra Associates. If excessively soft areas are observed and cannot be stabilized in place by compaction, the affected soils should be excavated and removed to firm bearing and grade restored with new structural fill. If the depth of excavation to remove unstable soils is excessive, use of a geotextile reinforcing/separation fabric, such as Mirafi 500X or equivalent, can be considered in conjunction with clean granular structural fill. Our experience has shown that, in general, a minimum of 18 inches of a clean, granular structural fill over the geotextile fabric should establish a stable bearing surface. Our study indicates that the colluvial soils contain a significant percentage of fines (silt -and clay -sized particles), which makes them difficult to compact as structural fill if they are too wet or too dry. Accordingly, the ability to use native soils from site excavations as structural fill will depend on their moisture content and the prevailing weather conditions when site grading activities take place. If grading activities are planned during the wet winter months, or if they are initiated during the summer and extend into fall and winter, the owner should be prepared to import wet weather structural fill. For this purpose, we recommend importing a clean granular soil that meets the following grading requirements. U.S. Sieve Size Percent Passing 6 inches 100 No. 4 75 maximum No. 200 5 maximum* *Based on the 3/4-inch fraction Prior to use, Terra Associates, Inc., should examine and test all materials imported to the site for use as structural fill. Structural fill should be placed in uniform loose layers not exceeding 12 inches and compacted to a minimum of 95 percent of the soil's maximum dry density, as determined by American Society for Testing and Materials (ASTM) Test Designation D-698 (Standard Proctor). The moisture content of the soil at the time of compaction should be within two percent of its optimum, as determined by this ASTM standard. In nonstructural areas, the degree of compaction can be reduced to 90 percent. 4.3 Excavations All excavations at the site associated with confined spaces (such as utility trenches) must be completed in accordance with local, state, or federal requirements. Based on current Occupational Safety and Health Administration (OSHA) regulations, the loose to medium dense colluvial soils would generally be classified as Type "C" soils. Accordingly, side slopes on temporary excavations should be laid back at a gradient of 1.5:1 (Horizontal: Vertical) or flatter. If these slope inclinations cannot be achieved due to site constraints, temporary shoring may be required. As noted above in the site preparation section, we recommend limiting excavation depths on -site for building construction to six feet. Page No. 4 • . September 14, 2005 Project No. T-840-10 Depending on the time of year and weather conditions when excavations take place, groundwater seepage may be encountered within excavations extending deeper. than one foot below existing surface grades. Based on our study, the volume of water and rate of flow into the excavation should be relatively light, depending on the time of year and the height of the exposed seepage face. Dewatering using conventional sump -pumps should be adequate in maintaining a relatively dry excavation. This information is provided solely for the benefit of the owner and other design consultants and should not be construed to imply that Terra Associates, Inc., assumes responsibility for job site safety. It is understood that job site safety is the sole responsibility of the project contractor. 4.4 Foundations We recommend the structure be supported on a raft foundation consisting of a connected grid of grade beams that bear on the existing colluvial soils or on structural fills placed above these soils. No isolated column.pads should be used for structural support. We recommend designing this foundation for a net allowable bearing capacity of 1,200 pounds per square foot (pso. For short-term loads, such as wind and seismic, a one-third increase in this allowable capacity can be used. Foundation subgrades should be prepared, as recommended in Section 4.2 of this report. Perimeter foundations exposed to the weather should bear at a minimum depth of 1.5 feet below final exterior grades for frost protection. For designing foundations to resist lateral loads, a base friction coefficient of 0.35. can be used. Passive earth pressures acting on the sides of the footings can also be considered. We recommend calculating this. lateral resistance using an equivalent fluid weight of 250 pounds per cubic foot (pcf). We recommend not including the upper 12 inches of soil in this computation because it can be affected by weather or disturbed by future grading activity. This value assumes the foundations will be constructed neat against competent soil and backfilled with structural fill, as described in Section 4.2 of this report. The values recommended include a safety factor of 1.5. 4.5 . Slab -on -Grade Floors Slab -on -grade floors may be supported on subgrade, as recommended in Section 4.2 of this report. Fill should not be placed to raise site grades above the existing elevations to support slab -on -grade floors. If the main level floor will be above existing site grades, we recommend the use of raised wood floors framed over a crawl space. Immediately below slab -on -grade floors, we recommend placing a four -inch thick capillary break layer of clean, free -draining, coarse sand or fine gravel that has less than three percent passing the No. 200 sieve. This material will reduce the potential for upward capillary movement of water through the underlying soil and subsequent wetting of the floor slabs. Page No. 5 • September 14, 2005 Project No. T-840-10 The capillary break layer will not prevent moisture intrusion through the slab caused by water vapor transmission. Where moisture by vapor transmission is undesirable, such as covered floor areas, a common practice is to place a durable plastic membrane on the capillary break layer and then cover the membrane with a layer of clean sand or fine gravel to protect it from damage during construction, and to aid in uniform curing of the concrete slab. It should be noted that if the sand or gravel layer overlying the membrane is saturated prior to pouring the slab, it will be ineffective in assisting uniform curing of the slab and can actually serve as a water supply for moisture transmission through the slab and potentially affect floor coverings. Therefore, in our opinion, covering the membrane with a layer of sand or gravel should be avoided if floor slab construction occurs during the wet winter months and the layer cannot be effectively drained. Other methods are available for preventing or reducing water vapor transmission through the slab. We recommend consulting with a building envelope specialist or contractor for additional assistance regarding this issue. 4.6 Retaining Walls The magnitude of earth pressure development on below -grade walls, such as basement walls, will partly depend on the quality of the wall backfill. We recommend placing and compacting wall backfill as structural fill. Wall backfill below structurally loaded areas, such as pavements or floor slabs, should be compacted to a minimum of 95 percent of its maximum dry density, as determined by ASTM Test Designation D-698 (Standard Proctor). In unimproved areas, the relative compaction can be reduced to 90 percent. To guard against hydrostatic pressure development, drainage must be installed behind the wall. A typical wall drainage detail is shown on Figure 3. With wall backfill placed and compacted as recommended and drainage properly installed, unrestrained walls can be designed for an active earth pressure equivalent to a fluid weighing 50 pcf. For restrained walls, an additional uniform lateral pressure of 100 psf should be included. These values assume a horizontal backfill condition and that no other surcharge loading (such as traffic, sloping embankments, or adjacent buildings) will act on the wall. If such conditions exist, the imposed loading must be included in the wall design. Friction at the base of the wall foundation and passive earth pressure will provide resistance to these lateral loads. Values for these parameters are provided in Section 4.4 of this report. 4.7 Drainage Surface Final exterior grades should promote free and positive drainage away from the building area. We recommend providing a gradient of at least three percent for a minimum distance of ten feet from the building perimeter, except in paved locations. In paved locations, a minimum gradient of two percent should be provided, unless provisions are included for collection and disposal of surface water adjacent to the structure. Page No. 6 • • September 14, 2005 Project No. T-840-10 To prevent surface water flowing off the adjacent hillside from impacting foundations, we recommend installing a surface swale along the uphill side of the house. The swale should extend the entire width of the building area and be located to collect and convey surface water to an appropriate point of controlled discharge into the plat stormwater system located in the street below the site. The collected surface water should not be discharged into the existing slope drainage system currently operating along the south side of the building site. When site grading details become available, we can provide supplementary recommendations for design and construction of the surface swale. Subsurface We recommend installing a continuous drain along the outside lower edge of the perimeter building foundations. The foundation drains should be tightlined separately from the roof drainage system and discharge into the plat stormwater system located in the street below the site. Subsurface drains must be laid with a gradient sufficient to promote positive flow to the point of discharge. All' drains should be provided with cleanouts at easily accessible locations. These cleanouts should be serviced at least once every year. 4.8 Slopes and Embankments All permanent cut slopes should be graded with a finished inclination.of no greater than 3:1. Upon completion of grading, the slope face should be trackwalked and appropriately vegetated or provided with other physical means to guard against erosion. Final grades at the top of the slope must promote surface drainage away from the slope crest. Water. must not. be allowed to flow uncontrolled over the slope face. If surface runoff must be directed towards the slope, the runoff should be controlled at the top of the slope, piped in a closed conduit installed on the slope face, and taken to an appropriate point of discharge beyond the toe. 5.0 ADDITIONAL SERVICES Terra Associates, Inc., should review the final project designs and specifications in order to verify that earthwork and foundation recommendations have been properly interpreted and incorporated into project design. We should also provide geotechnical services during construction to observe compliance with our design concepts, specifications, and recommendations. This will allow for expedient design changes if subsurface conditions differ from those anticipated prior to the start of construction. 6.0 MMATIONS We prepared this report in accordance with generally accepted geotechnical engineering practices.

The approximate test pit locations are shown on Figure 2. The test pit logs are presented on Figure A-2. A geotechnical engineer from our office conducted the field exploration, maintained a log of each test pit, classified the soils encountered, collected representative soil samples, and observed pertinent site features. All soil samples were visually classified in accordance with the Unified Soil Classification System (USCS) described on Figure A-1. Representative soil samples obtained from the test pits were placed in sealed containers and taken to our laboratory for further examination and testing. The moisture content of each sample was measured and is reported on the test pit logs. Grain size analyses were performed on two samples. The results are shown on Figure A-3.

The purpose of our services was to observe the site conditions and to provide recommendations to the City of Edmonds (City) Building Official and Engineering Division staff related to our assessment of landslide conditions and the potential for an imminent hazard to City -owned facilities, the general public, or the private property residents. Our services were requested by Don Fiene, Assistant City Engineer, on January 31, 2006 and confirmed by Task Order No.. 06-01 under Landau Associates' On -Call and Emergency / Disaster Response Geotechnical Engineering Agreement with the City of Edmonds. BACKGROUND AND OBSERVATIONS Don Fiene, Assistant City Engineer; Ann Bullis, Assistant Building Official; Damon Roth, and Dennis Stettler of Landau Associates observed the above -described landslide on the afternoon of January 31, 2006. The landslide was viewed from below, looking up from 73`d Place West, and from the top, looking down from the yard of the Bosch residence at 16116 72"d Avenue West. Mr. Bosch spoke to us briefly during our site visit and provided some background information. Our observations were limited to brief visual observations. No measurements were taken and no attempts were made to closely examine I the slope or slide debris, other than what could be readily seen by standing at the bottom or top of the slope. We understand that the landsliding was observed by a resident of 73`d Place West on Monday, January 30, 2006, at about 4:30 p.m. The landslide was preceded by over a month of unusually wet weather with precipitation significantly above typical winter rainfall levels. ENVIRONMENTAL I GEOTECHNICAL I NATURAL RESOURCES 130 2nd Avenue South • Edmonds, WA 98020 • (425) 778-0907 • fax (425) 778.6409 • www.landaLAnc.com SEATTLE • SPOKANE • TACOMA • PORTLAND The landslide occurred at the top of a steep, northwest -facing slope immediately west of the northwest corner of the Bosch residence. The location of the current landslide corresponds approximately to the location of a previous landslide that occurred on about February 13, 2005, as documented in a letter by Landau Associates to the City dated February 22, 2005. On September 16, 2003, ground cracking was also observed by Landau Associates and City personnel at the top of the bluff at this approximate location. This ground cracking was documented in a Landau Associates letter to the City dated September 25, 2003. The previously observed ground cracking had been noted when Landau Associates and City personnel were onsite observing a landslide on the same slope that had occurred about 200 ft north of the current landslide location. Following the observation of ground cracking in 2003, sections of heavy tarp were reportedly placed over the ground by Mr. Bosch and secured in place by driven steel rebar. At the time .of our observation on February 14, 2005, the heavy plastic tarps were still in place, but the ground beneath the tarps at the location of the previous ground cracking had failed and slid downslope. At the time of our most recent observations on January 31, 2006, the plastic tarps were still in place over a portion of the top of the slope. The 2005 landslide created a headscarp that was estimated to be approximately 8 to 10 ft from the northwest corner of the house and about 5 to 6 ft from a porch. The upper portion of the 2005 slide 1 formed a steep scarp area, which flattened to a slight "bench" about 20 ft below the top of the scarp. Soil exposed in the upper portion of the slope appeared to be relatively dry at the time of our 2005 site visit. At the slight "bench," seepage and wet zones were observed in 2005 with seepage flowing downslope through the recent slide debris and ultimately emerging as surface water drainage that was intercepted by catch basins along the edge of 73rd Place West. Slide debris in 2005 had been deposited or flowed into the area at and below the "bench" and was mixed with the trees and undergrowth on the lower portions of the slope. The extent of the current landslide as observed on January 31, 2006, appeared to be within the general boundaries of the 2005 landslide. The top of the 2006 landslide did not appear to extend to the top of the 2005 headscarp and as such there appeared to be little to no additional loss of ground from the top of the bluff. Some of the material involved in the 2006 landslide may represent landslide debris and colluvium that had accumulated mid -slope on the "bench" observed at the time of the 2005 landslide. The 2006 landslide debris produced an accumulation of soft, wet soil mixed with organic material near the base of the slope on Lot 2 of the Lorian Woods subdivision. Seepage was observed coming down lower portions of the slope and emerging from the base of the landslide debris at the toe of the landslide. The 2006 landslide destroyed a drainage structure that formed a portion of the City's landslide drainage system in this area. Remnants of the dislocated drainage structure (including a large diameter 2/17/06 \\Edmdaza\projects\074\133\Fileroom\R\BoschLaudslide_lmdoc 2 LANDAu ASSOCIATES corrugated metal pipe that formed the collection structure) are present near the toe of the landslide debris. Segments of black, corrugated pipe was also observed near the base of the.slope. This pipe material did not appear to be a part of the City's drainage system. Mr. Bosch indicated that he had previously observed someone (thought to be the property owner from Lot 2 in the Lorian Woods subdivision) working on the slope to apparently try to intercept some of the seepage and springs emerging from the slope. ASSESSMENT AND RECOMMENDATIONS We offer the following comments and assessment to address the City's questions on whether the landslide and present condition pose an imminent hazard to City -owned facilities, the general public, or the occupants of the Bosch residence and downslope residences. This assessment is based on a limited observation of the site conditions and our experience with similar landslide conditions, and not on a detailed evaluation of the site conditions. Our limited assessment for the purpose of assessing imminent risk should not be construed as a replacement for a detailed geotechnical evaluation and recommendations developed by a licensed geotechnical consultant retained by the property owners to address the longer - term risk posed by the landslide hazard. The location of the recent landslide appears to be consistent with the general location of a landslide in 2005 and ground cracking observed in 2003. The 2006 landslide involved only surficial materials and there.was no evidence that the landslide represents a larger, deep-seated failure. The entire bluff in the Meadowdale area is a known landslide hazard zone. The observed landslide is consistent with other naturally occurring landslides along the Meadowdale Bluff. Springs and seepage emerge from this slope above the Lorian Woods subdivision and the slopes above these springs are subject to repeated landsliding and slope movement as the landslide headscarp continues to retreat. The landslide on this slope last year had removed the vegetation and exposed the soil on the upper portions of the slope to rainfall and erosion. Landslide debris from 2005 that had accumulated near the midpoint and lower on the slope had the opportunity to become wet from the recent heavy rainfall events and the rainfall was apparently sufficient to reinitiate the landslide, at this location. The observed landslide was likely caused by the heavy precipitation over the last month or more, possibly combined with natural groundwater seepage zones that are present in the steep portions,of the bluff. The seepage zones and the observed landslide are located well above a City interceptor drainage system and the landslide debris actually flowed down and destroyed a portion of the drainage system. The purpose of the City drainage system is to capture some of the localized surface water and water emerging from springs on the slope that would otherwise infiltrate into the ground below the drainage system. Implementation of the drainage system and other drainage improvements in the Meadowdale 2/17/06 \lEdmdata\projects\074\133\Fileroom\R\BoschLmdslide_ltr.doc 3 LANDAU ASSOCIATES I I area is thought to contribute Ito the overall increased stability of the Meadowdale landslide complex located downslope from the location of the interceptor drainage system. The interceptor drainage systems do not reduce the groundwater levels in the slopes above the systems or reduce the seepage from these areas. Accordingly, it is our opinion that the observed landslide was not caused by or related to the presence of the City's interceptor drainage system. , The landslide has impacted and destroyed some of the City drainage facilities located on the , lower portion of the slope. It is our opinion that the presence of the landslide debris and the recurring slope movement at this location make restoration of the City drainage system impractical at this location at this time. We suggest that this situation be re-evaluated for possible maintenance or improvements during drier weather in late spring or summer. The landslide occurred on private property and extended into adjacent private property. Therefore, the general public traveling on public rights -of -way would not be affected by this landslide. With respect to the Bosch residence, the 2006 landslide has not materially changed the slope condition as compared to the condition following the 2005 landslide. Landau Associates provided comments and recommendations in our February 22, 2005 letter following the 2005 landslide and the 2006 landslide does not alter the general findings or recommendations of that letter. The debris from this landslide extends into an undeveloped lot within the Lorian Woods subdivision. The owner of this property should be advised of this condition. Mudslides and landslide debris from the bluff above can impact any development on the property below and any `future development plans should consider and address this issue. This letter was prepared for the exclusive use of the City of Edmonds for specific application to the evaluation of public safety concerns related to the Bosch property landslide. Within the limitations of scope, budget, and schedule, our services have been conducted in accordance with generally accepted geotechnical practice. No other warranty, express or implied, is made as to the professional opinions and advice included in this report. We appreciate this opportunity to be of service to the City of Edmonds.

Affidavit of Publication from The Everett Herald, dated January 21, 2009 Upon consideration of the testimony and exhibits submitted at the open record hearing, the Hearing Examiner enters the following findings and conclusions: FINDINGS The Applicants requested a height variance (file no. V-08-53), a critical area reasonable use variance (V-08-72), and a minor PRD amendment (LL-08-75) related to a proposed single-family residence at 16007 - 73`d Place West in Edmonds, Washington.' The Applicants request a nine -foot height variance from the maximum allowed 25 feet to a maximum structure height of 34 feet. The critical area variance is requested to allow development of a lot that is fully encumbered by critical areas and associated buffers. The minor PRD amendment would allow a minor adjustment to the southern property line, jogging the boundary line south 3.5 feet, increasing the size of the Applicants' parcel by 175 square feet, to maintain all structural elements of the residence within the lot boundaries. It would also allow minor modification to the PRD's CC&Rs to be effectuated to allow the eaves of the proposed structure to intrude into the required ten - foot building setback from the shared lot line to the north. Exhibit 1, pages 1-3; Exhibits 3, 4, 5, 6, 7, 8, 9, 10, 1]. and 12. 2. The subject property, which is currently undeveloped, is Lot 2 of the Lorian Woods PRD, located in a single-family residential neighborhood in northern Edmonds. The PRD was approved in 1990 prior to the Growth Management Act and critical area regulations. As explained by City of Edmonds Planning Division Staff (Staff); the restrictions on individual lots that could result from the critical areas on -site were not fully appreciated at the; time of PRD approval, as it predated adoption of critical areas regulations. Six of the ten lots within the PRD are developed with single-family residences. The Applicants bought Lot 2 in 2004. Exhibit 1, pages 5-6, Testimony of Mr. Lien; Exhibit 13. . 3. In preparation for site development, the City conducted a critical areas review (CRA- 2006-0147) of the site. Exhibit 14. Subsequent critical areas field studies revealed that the site contains a Category IV wetland and an associated Type Ns (seasonal, non -fish bearing) stream. According to the City's critical areas regulations, Category IV wetlands require a 35-foot buffer, and Ns streams require a 25-foot buffer. ECDC 23.50.010.F, ECDC 23.90.040.D. The stream and associated buffer are entirely located within the wetland and its buffer. The wetland and required 35-foot buffer encumber the entire parcel. Exhibit 7, seepage 24. 4.

Lot 2 sits on a steep to moderate west aspect slope that runs from the eastern property boundary to 73r' Place West. Development of the subject property is constrained by slopes on -site and on the adjacent open space (Parcel A) to the east. - The proposed building site slopes down to the west at grades ranging from 10 to 50 percent. East of the building envelope, site slopes approach vertical grades.

In April 2007, the Applicants received approval of a conditional use permit (CU-06-104) for drainage improvements and tree removal from the site and the adjacent common area. As part of the review process for CU-06-104, a geotechnical analysis, planting"plan, and peer review of the geotechnical analysis and planting plan were conducted. In August 2007, the Applicants applied for a fill and grade permit (BLD-07-834 and BLD-07-833) for additional drainage work (on their site and the adjacent common area) to help stabilize the hillside above their building site in preparation for development. The planting plan prepared in conjunction with CU-06-104 was revised, underwent further peer review, and received approval during the review of the 2007 fill and grade permits. The Applicants applied for an additional conditional use permit (CU-08-36) in May 2008 to remove a sequoia tree not identified for removal under CU-06-104. Given that the sequoia would be removed in order to construct the proposed home, Staff advised the Applicants to withdraw the CU-08-36 application and address the tree removal under the instant critical area reasonable use variance application (V-08-72). Exhibit 1, pages 3-4; Testimony ofMr. Lien. 6. The subject property is zoned Single -Family Residential (RS-20). The minimum lot area for standard subdivision lots in the RS-20 zone is 20,000 square feet, and the minimum lot width is 100 feet_ The maximum residence height allowed is 25 feet. Edmonds Community Development Code (ECDC)16.20.030. Parcels surrounding the Lorian Woods PRD are zoned RS-20 and RS-12. According to Staff, the neighborhood is characterized by moderate to upscale homes, many of which have views of Puget Sound and the Olympic Peninsula. Exhibit 13; Exhibit 1, page 5. 7. Lot 2 is 5,897 square Beet in area. The longest of its four boundary lines is 104 feet long, with all other boundaries of much shorter lengths, resulting in a trapezoidal shape that would not satisfy the minimum 100-foot lot width requirement of the RS-20 zone. Its substandard area and width were approved for residential development via the City's PRD process in 1990. Exhibit 1, page 8; Testimony ofMr. Lien; Exhibit 12, page 2. 8. The land in and around the Lorian Woods PRD has been geotechnically observed by the same engineering firm periodically over the past 20 years. The Applicants consulted with this same firm to review and prepare geotechnical engineering for the proposed residence. Professional geotechnical recommendations for development of the site restricted the potential placement of the residence within the subject property. These recommendations include (but are not limited to): limiting temporary basement cuts to a height of eight feet, construction of a catchment wall to control .soils originating above Findings, Conclusion4 and Deedsion City of Edmonds Hearing Examiner Isaacson, Nos V-2008-53, V-W72, and LL-08-75 page 4 of 16 . . ........... ... the lot; prohibiting installation of a sliding glass door on the eastern main floor; and placement of bedrooms on an upper story to protect sleeping inhabitants in the event of a nighttime landslide. Site evaluation and more detailed geotechnical recommendations for grading, drainage, and other design elements are detailed in Exhibit 20..Testimony ofMr. O'Brien; Testimony ofMr. Lie; Exhibit 21; Exhibit 20. 9. Given these geotechnical constraints, the Applicants retained professional architects to design the residence to fit into the topography of the parcel with minimal impact and maximum safety. The location of the residence was situated as near to 73`d Place West as possible, both to minimize cutting into the slope and to minimize the length of the required driveway. Inclusion of the required catchment wall and an upper floor for primary bedrooms added to the height of the house. The required limitation to eight -foot cuts prevented the house from being sunk deeper into the site, as would have been done on a less steep parcel.-' Exhibit 4, pages 61-62; Testimony ofMr. O'Brien. 10, The Applicants' geotechnical consultants opined that, if the geotechnical engineering recommendations in the reviews they conducted are incorporated into site design and construction, development of the site as proposed would not increase the risk of instability on the site or on adjacent properties. Exhibit 20, pages 8-9; Testimony ofMr. Lie. 11. The City's geotechnical consultant, after reviewing the Applicants' geotechnical submittals, recommended that slope replanting and associated landscaping plans for the property be incorporated into the current permit process in order to protect slope stability. Exhibit 22, page 3. 12. The conditions of approval for the 1990 Lorian Woods PRD include condition number 22, which states: "The Applicants shall draft all private restrictive covenants prior to final approval of the plat." Exhibit 27, page 21, Staff testified that covenants, conditions, and restrictions (CC&Rs) were "recorded with the plat" because they were included in a note on the face of the recorded plat document and because they were considered by City Council at time of final plat review. Testimony ofMr. Lien. 13. Section 7.5.1 of the CC&Rs requires a minimum living area of 3,000 square feet, excluding the garage for every residence. Sections 7.5.2 through 7.5.4 establish minimum square footage for various rooms in the residences, including master and spare bedrooms and living rooms. Section 7.5.5 requires all portions of the structure, including eaves, to be located within the boundaries of each lot and to be set back ten feet from any shared lot lines. Finally, another section requires the roof to be finished with shakes or tiles. The Applicants argue that they are bound legally to comply with the CC&R provisions. Exhibit 4; Tesdmony ofMr. Isaacson. 3 The driving factor in restriction depth of cots to eight feet relates to worker safety during construction. Tesdmo y ofMr. Lie. Rindings, Conclusions, and Decision City of Edmonds Hearing Er ner Isaacson, Nos v 2008-53, V-08-72, and LL-08-75 page 5 of 16 14. According to Staff, the City generally does not enforce CC&Rs; however because the CC&Rs in the present case resulted from a PRD condition of approval from the hearing examiner, were submitted to the City Council prior to final approval for the PRD, and are mentioned on the face of the PRD that was signed by the City, Staff believes that in the standards established by the CC&Rs in the present case should be recognized as requirements for development of Lot 2. Testimony ofMr. Lien; Exhibit 1, page 7. 15. The CC&Rs' requirement for a three -car garage established the north -south dimension of the foundation. Room sizes were also driven by the requirements of the CC&Rs. The pitch of the roof (at 4:12) is the minimum pitch recommended in the roofing industry for the materials allowed by the CC&Rs. These factors contributed to the Applicants' ultimate inability to construct a residence in conformance with the 25-foot height limitation of the RS-20 zone. Testimony ofMr. O'Brien; Exhibit 4, page 61-62. 16. As proposed, the residence would impact 2,930 square feet ofthe Category IV wetland and 3,425 square feet of the associated buffer. Exhibit 7. 17. Hydrology of the on -site wetland crosses the site and drains to the City stormdrain in 73`4 Place West. The proposal would not alter this direction of flow; hydrology would still be directed to the City stormdrain, avoiding impacts to off -site properties related to flooding or increased site instability. Exhibit 7; Testimony ofMr. Lie. 18.. In its present, predevelopment condition, the small, urban, slope wetland has limited functions and values. Its hydrology emerges from seeps on the slope, 'and due to the steepness of the slope, drains quickly, providing little to no function for stormwater storage or flood flow attenuation. Being small and cut off from other critical areas, it provides minimal value as wildlife habitat. Because it is impossible to avoid impacts to the critical areas on -site, the Applicants proposed a mitigation plan based on enhancement of the remaining wetland and buffer areas through planting trees and shrubs on -site and in the adjacent open space off -site. A total of 38 trees, 245 shrubs, and 860 herbs/groundcover plants would be installed. The proposed mitigation plan is consistent with the mitigation sequencing recommended in the Washington Department of Ecology .manual Wetland Mitigation in Washington State, Part 1• Ago-gy Policies and Guidance. The plan includes monitoring. the plantings for survival for a period of three years. ' The mitigation would offset impacts from construction and result in increased overall functions and values of the on -site wetland, improving water quality and wildlife habitat. The plantings would stabilize the slope, reduce erosion (improving water quality off -site), and increase species diversity and vegetative structure, resulting in increased cover and forage opportunities for birds and small mammals. Exhibit 7. 19. The proposed single-family residence would contain 3,299 square feet in living area (excluding garage, stairways, and elevatorl making it the smallest residence in the PRD.4 4 TestimM from the Applicants' architect revealed that geotechmcal and CC&R requirements established the necessary minimum footprint for the proposed residence, and that the apparently "extra" 299 square feet could not be shaved off of the footprint of the residence, meaning that the 299 square feet did not represent "extra" impact to the critical areas. Testimony ofMr. O'Brien. Findings Conclusions, and Decision City of Erbnonds Nearing Ewminer Isaacson, Nos V-2008-53, V-08-72, and LL-08-75 page 6 of 16 It was specifically designed to fit into the existing site topography, incorporating a "stair step" design keeping the living area as close to grade as possible. According to the Snohomish County website, its size would be consistent with existing homes in the surrounding neighborhood. The PRD itself was designed to be compatible with the natural constraints of the overall property through preservation of 74% of the overall site in open space. Exhibit 1, pages 10-11; Testimony ofMr. O'Brien; Exhibit 27, pages 5-6. 20. Due to its location on the slope, the proposed residence would not infringe on views of the surrounding properties. Exhibit 1, page 11, Testimony ofMr. Lien; Testimony ofMr. O'Brien. 21. Because of the previously discussed geotechnical site restrictions and the minimum dimensions of the garage required by the CC&Rs, the Applicants' architects were unable to design the residence such that all portions of the structure remained within the development envelope prescribed by the PRD: no portion of the structure — including eaves — is allowed to protrude into the required ten -foot setback from the shared property boundary with Lot 1(the site's north boundary). The ten -foot setback is required by subsection 7.5.5 of the CC&Rs. To remedy this conflict, the Applicants have proposed a minor PRD amendment, allowing an exception for Lot 2 from subsection 7.5.5. The Lorian Woods Homeowners Association approved the proposed minor PRD amendment. Exhibit 10, Exhibit 1, page 7; Testimony ofMr. O'Brien; Exhibit 28. 22. Similarly, the Applicants' architects were unable to design the residence such that all parts of the structure remained within the boundaries ofLot 2. As designed, a small portion of the eaves would protrude across the southern lot line into the adjacent open space parcel. Because such a protrusion is not allowed and because the residence cannot be moved within the parcel or reduced in size, the Applicants requested a minor amendment to the lot boundary (LL-08-75). As proposed, a 50-foot by 3.5-foot portion of Parcel A would be added to Lot 2 (for a total increase of 175 square feet). The proposed lot line adjustment necessitates approval of an amendment to the PRD's CC&Rs. On January 15, 2009, the Lori= Woods PRD homeowners' association agreed to the minor CC&R amendment, allowing alteration of the property line. Only the eaves of the structure would be located within this area, not the footprint of the building. Exhibit 10, Exhibit 11; Exhibit 12; Testimony ofMr. O'Brien; Testimony ofMr. Isaacson. 23. City Staff testified that reduction of Parcel A by 175 square feet would not be inconsistent with the conditions or requirements of the 1990 PRD approval. It would not change the number or orientation of lots, and it would not reduce any tenant or public use area within Parcel A, due to the presence of the slope. Staff recommended that approval of the variances be conditioned on prior recording of the lot line adjustment. Exhibit 1, pages 18, 21; Testimony ofMr. Lien. 24. While the PRD would allow 100% lot coverage, the proposed residence would have a footprint of considerably less than 100%. Exhibit ],page 6; Exhibit 5, Sheet 1.

Construction of single-family residences is exempt from SEPA review pursuant to WAC 197-11-800(l)(b)(i). The exemption in WAC 197-11-800(6)(b) would apply to the height variance request, but not the critical area reasonable use variance request. The Lonan Woods PRD was reviewed for compliance with the requirements of the State Environmental Policy Act (SEPA) and a Mitigated Determination of Non -Significance (MDNS) issued on December 15, 1989 (Exhibit 24). Site work for the subject property underwent SEPA review for the tree removal applied for under CU 06-104 and a Determination ofNonsignificance (DNS) issued on March 21, 2007 (Exhibit 25). Relating to the instant applications, on December 29, 2008 the City of Edmonds adopted the DNS issued on March 21, 2007, on the grounds that the proposals would not result in any additional environmental impacts beyond those already evaluated under the adopted document (Exhibit 26). No appeals of the DNS adoption were filed. Exhibit 1, pages 4- 5, Testimony of Mr. Lien; Exhibits 24, 25, and 26. 26. Development of Lot 2 must comply with the mitigation measures imposed in the 1989 MDNS issued for the Lorian Woods PRD, which include the following: • Development of the subject property shall be subject to review under Chapter 19.10 of the Edmonds Community Development Code; • The Applicant shall submit an erosion control plan for review and approval by the City Engineer prior to issuance of any grading permit. • No grading shall take place on the property between the months of October to May. • All grading work shall be done during normal working hours of the City of Edmonds, 8 am to 5 pm Monday to Friday. • The Applicant shall be responsible for providing verification of the total amount of excavated material prior to finalizing the grading permit. A soils engineer shall monitor the site during grading. • Development of individual lots shall be subject to environmental review and compliance with Chapter 19.05 of the ECDC. All permits shall be subject to review by the City of Edmonds soils engineer. • Development shall conform to the recommendations found in the report from Terra Associates, Inc., dated June 6, 1989 and any recommendations from the City's consulting soils engineer, Landau Associates.

The options available to the City to influence the quality of housing to all citizens should be approached realistically in balancing economic and aesthetic considerations, in accordance with the following policies: B.1 Encourage those building custom homes to design and construct homes with architectural lines which enable them to harmonize with the surroundings, adding to the community identity and desirability. B.3 Minimize encroachment of view of existing homes by new construction or additions to existing structures. B.6 Require that new residential development be compatible with the natural constraints of the slope, soils, geology, vegetation and drainage. City of Edmonds Comprehensive Plan (2006), pages 53-54, Exhibit 1, page 10. 28. Notice of Application and Notice of Hearing were published in the Herald Newspaper and posted at the subject site, as well as the Public Safety Complex, Community Development Department, and the Library. All notices were also mailed to residents and owners within 300 feet of the site, consistent with the noticing provisions of ECDC 20.91. Exhibit 1, page 5, Exhibit 31. 29. The City received written and oral public comments on the applications. One upslope neighbor expressed concerns regarding slope stability. Exhibit 32. This neighbor appeared at hearing and testified that from the documents and geotechmcai and architectural testimony at hearing, she felt the Applicants "are doing a good job" of designing with slope stability in mind. Testimony ofM& Neal. Additional oral comment addressed the fact that some of the geotechnical studies and earlier applications are more than one year old, and expressed concern that the instant applications — if approved — would only be valid for a period of one year. Testimony ofMr. Rutledge. Additional written comment expressed the opinion that the size and shape and location of Lot 2 should be considered self-created hardship on the part of the previous property owner (the PRD developer). Exhibit 33. 30. In response to the question regarding whether the size, shape, and location of Lot 2 should be considered self-created hardship on the part of the previous owner, Staff testified that approval of the PRD by the City was the act that created Lot 2 as a developable residential lot and that the Applicants had no part in creating the special circumstances constraining development of Lot 2.

Findings, Conctusions� and Decision City ofFdmonds Hearing Ecaminer Isaacson, Nos V 2008-53, V-08-72, and LL-08-75 page 9 of 16 - k CONCLUSIONS Jurisdiction: The Hearing Examiner has jurisdiction to hear and decide variance requests pursuant to Edmonds Community Development Code 20.100.010(B). Minor PRD amendments can be approved pursuant to ECDC 20.35.110.A Such a decision would normally be reviewed for approval administratively; however due to the interconnectedness of this application with the two requested variances, the matter is appropriately consolidated with them pursuant to ECDC 20.90.010(B) and decision authority in the matter is appropriately delegated to the Examiner by the Director. Criteria for Review: Variance Pursuant to ECDC 20.85.010, the Hearing Examiner may not grant a variance unless the following findings can be made: A Special Circumstances. That, because of special circumstances relating to the property, the strict enforcement of the zoning ordinance would deprive the owner of use rights and privileges permitted to other properties in the vicinity with the same zoning. 1. Special circumstances include the size, shape, topography, location or surroundings of the property, public necessity as of public structures and uses as set forth in ECDC 17.00.030 and environmental factors such as vegetation, streams, ponds and wildlife habitats. 2. Special circumstances should not be predicated upon any factor personal to the owner such as age or disability, extra expense which may be necessary to comply with the zoning ordinance, the ability to secure a scenic view, the ability to make more profitable use of the property, nor any factor resulting from the action of the owner or any past owner of the same property, B. Special Privilege. That the approval of the variance would not be a grant of special privilege to the property in comparison with the limitations upon other properties in the vicinity with the same zoning; C. Comprehensive Plan. That the approval of the variance will be consistent with the comprehensive plan; A Zoning Ordinance. That the approval of the variance will be consistent with the purposes of the zoning ordinance and the zone district in which the property is located; E. Not Detrimental. That the variance as approved or conditionally approved will not be significantly detrimental to the public health, safety and welfare or injurious to the property or improvements in the vicinity and same zone; Findings Conclusions, and Decision City of Edmonds Hearing Examiner Isaacson, Nos V-2008-53, V-08-72, and LL-08-75 page 10 of 16 F. Minimum Variance. That the approved variance is the minimum necessary to allow the owner the rights enjoyed by other properties in the vicinity with the same zoning. Criteria for Review: Critical Area Reasonable Use Variance Pursuant to ECDC 23.40.210.A.2, a reasonable use exception may be authorized as a variance only if an Applicant demonstrates that: 1. The application of this title would deny all reasonable economic use of a property or subject parcel; 2.. No other reasonable economic use of the property consistent with the underlying zoning and city comprehensive plan has less impact on the critical area; 3. The proposed impact to the critical area is the minimum necessary to allow for reasonable economic use of the property; 4. The inability of the applicant to derive reasonable economic use of the property is not the result of actions by the applicant after the effective date of the ordinance codified in this title or its predecessor, 5. The proposal does not pose an unreasonable threat to the public health, safety, or welfare on or off the development proposal site; 6. The proposal minimizes net loss of critical area functions and values consistent with best available science; and 7. The proposal is consistent with other applicable regulations and standards. Further, ECDC 23.40.210.B states that a variance may be granted if the applicant demonstrates that the requested action conforms to all of the following specific criteria: L. . Special conditions and circumstances exist that are peculiar to the land, the lot or something inherent in the land and that are not applicable to other lands in the same district. 2. The special conditions and circumstances do not result from the actions of the applicant. 3. A literal interpretation of the provisions of this title would deprive the applicant of all reasonable economic uses and privileges permitted to other properties in the vicinity and zone of the subject property under the terms of this title, and the variance requested is the minimum necessary to provide the applicant. with such rights. .` 1•indings, Conclusions and Decision City of Fdmondr Hearing Examiner Isaacson, Nos V-2008-53, V-08-72, and LL-08-75 page 11 oj16 4. Granting the variance requested will not confer on the applicant any special privilege that is denied by this title to other -lands, structures or buildings under similar circumstances. 5. The granting of the variance is consistent with the general purpose and intent of this title, and will not further degrade the functions or values of the associated critical areas or otherwise be materially detrimental to the public welfare or injurious to the property or improvements in the vicinity of the subject property; and 6. The decision to grant the variance is based upon the best available science and gives special consideration to conservation or protection measures necessary to preserve or enhance anadromous fish habitat. Criteria for Review. Minor PRD Amendment: Lot Line Adjustment Pursuant to ECDC 20.35.110.A, minor changes to lot lines which do not change the number or orientation of the lots approved through the PRD process may be authorized if these changes ... are due to circumstances not known at the time the final plan was approved .... Minor location, siting, or lot line changes shall be performed through a lot line adjustment between a property owner of a specific lot and the homeowners' association as the owner of the open space. No change authorized by this section may case any of the following: a A change in the use, intensity or character of the development; b. An increase in the overall ground coverage of structures; c. A decrease in approved traffic circulation utility; and/or d. Any reduction in public use or tenant use areas which include but are not limited to perimeter buffers/setbacks, utility easements, required critical areas open space, usable open space, off-street parking, loading zones, right-of-way or pavement width. Conclusions Based on Findings: Critical Area Variance 1. Application of the standard prohibition for development of critical areas and ofthe 35- foot buffer for Category IV wetlands would deny the Applicants all reasonable use of their property, because the wetland and buffer encumber the entire site. No other use of the site would be consistent with the zoning of the underlying land or the PRD approval. The only option with less impact on the critical areas is not to develop the site, which would deprive Applicants of reasonable use. Findings Nos 2, 3, 4, 6, 7, and 18. 2. In addition to the site's encumbrance by wetland and associated buffer, it is severely constrained by steep slopes. While the PRD would allow up to 100% site coverage by structure, the Applicants propose a residence that fits within the building envelope identified as geotechnically feasible by credible professionals. The residence cannot be Rndings� Conclusions, and Decision City of Edmonds Hearing Examiner Isaacson, Nos. V-2008-53, V-08.72, and LL-08-75 page 12 of 16 moved within the building envelope nor compacted into a less spread out footprint due to the requirements to stair step the structure into the hillside and to keep cuts to a maximum of eight feet. The proposed impact to the critical areas is the minimum necessary to allow use of the site. The Examiner does not rely on the requirements of the CC&Rs to conclude that the record demonstrates compliance with the minimum necessary criterion for critical area variance approval. Findings Nos 3, 4, 7, 8, 9, 10, 16, and 24, 3. No action taken by any property owner after the effective date of the critical areas regulations has resulted in the Applicants' present inability to derive use of the site without variance approval. The existence of wetlands, stream, and steep slopes is not the result of any action by the Applicants or any former owners of the property. The City approved Lot 2 as a buildable lot in 1990, prior to adoption of the City's critical areas regulations. The Applicants did not take possession until 2004. Findings Nos 2, 3, 4, 8, 9, and 30. 4. With conditions ensuring that all geotechnical recommendations are followed during site preparation and construction, development of Lot 2 would not pose an unreasonable threat to public health or safety. Credible professional engineering testimony established that construction consistent with geotechnical recommendations would not increase the risk of slope instability. Runoff from the site would be captured and directed into stormdrains. The proposed plantings would stabilize the slope, provide enhanced water quality, and improve wildlife habitat for the remaining critical area. Findings Nos 8, 9, 10, 17, 18, and 26. 5. While the proposals would result in impacts to critical areas, this is allowed pursuant to the critical areas regulations. ECDC 23.50.010.E states, "Activities and uses that result in unavoidable and necessary impacts may be permitted in Category 3 and 4 wetlands and associated buffers in accordance with an approved critical areas report and mitigation plan." The City has reviewed and approved the Applicants' proposed planting/mitigation plan. Undeveloped portions of the site and off -site areas within adjacent Parcel A would be enhanced, resulting in smaller but overall higher functioning critical areas. The proposed mitigation plan is consistent with state recommended mitigation sequencing. Findings Nos 3, 16, 18, and 19. 6. Site slopes result in geotechnical limitations on development that by themselves constitute `special circumstances' for the purposes of variance application review. The Applicants (and previous owners of the property) are in no way responsible for the slopes and resulting geotechnical limitations. The Examiner does not rely on the size or location of the lot in concluding that special circumstances have been demonstrated Findings . Nos. 4,8,9,10,and 19. 7. Single-family residential development of Lot 2 would not constitute special privilege. The proposed residence occupies less of the site than may be developed according to PRD approval. The size of the residence would be smaller than existing residences within the PRD and comparable to existing residences in the surrounding neighborhoods. Findings Nos 2, 4, 6, 19, and 24. Findings, Conclusion& and Decision City of Edmonds Hearing Examiner Isaacson, Nos V-2008 53, V-08-72, and LL-08-75 page 13 of 16 • Height variance 1. Due to significant geotechnical limitations resulting from the steep slopes on -site, strict enforcement of the 25-foot maximum height restriction of the RS 20 zone would deprive the Applicants ofthe right to develop Lot 2. Geotechnical recommendations that restrict development of the site include the location of the building pad, the limitation to eight - foot maximum cuts, the requirement to install a catchment wall, and the requirement to place bedrooms on an upper floor in the event of a nighttime slide event. These factors, as established by credible engineering expert testimony, satisfy the requirement that special circumstances dictate the need for a height variance. But for the slopes and resulting geotechnical limitations, no height variance would be necessary. Neither the Applicants nor any previous owner of Lot 2 is responsible for the slopes and resultant geotechnical limitations. Findings Nos 2, 4, 7, 8, 9, 10, and 30. 2. Approval of the variance would not be a grant of special privilege. The variance would only allow residential use of an approved lot in a PRD in an RS-20 zone. Findings Nos. 2, 4, 6, and 19. 3. The variance would be consistent with the Comprehensive Plan. The residence would not impact views from surrounding residences. Findings Nos 20 and 27. 4. The variance would be consistent with the purposes of the zoning ordinance. One of the purposes of the zoning ordinance is to protect the character of residential uses within the City by regulating individual parcels of land to prevent unreasonable detrimental effects. ECDC 16.00.010(B)(3). One of the purposes of the residential zones is to preserve views. ECDC 16.10.000. The variance would be consistent with these purposes because it would result in development consistent with existing residences in the neighborhood, would not increase slope instability, and would not impact views. Findings Nos 10, 19, and 20. With conditions ensuring geotechnical recommendations are fully incorporated into design and construction, the height variance, which would allow construction of a residence on -site, would not be detrimental to the public health, safety, or welfare, or injurious to property or improvements in the vicinity. Stormwater runoff would be directed into stormdrains, consistent with the predeveloped condition. Credible evidence supports the conclusion that development of the lot would not increase risk of slope instability. Findings Nos 8, 9, 10, 17, and 18. 6. Due to the slopes and resulting geotechnical limitations on construction, the nine -foot variance would be the minimum necessary to allow the Applicants the right to develop their residential property. Geotechnical limitations directly resulting from the steepness of the slope limit the depth of cuts, require construction of a catchment wall, and require placement of bedrooms on an upper floor. These factors drive the need for a structure that is taller than 25 feet. The height of the residence would not adversely impact any surrounding properties because of the lot's placement on the slope. The size of the proposed residence would be compatible with other residences in the neighborhood. Findings Nos. 4, 8, 9, 10, 19, and 20. Frn&ngs, Conclusions, and Decision City ofE&nonds Nearing Examiner Isaacson, Nos., V-2008-53, V-08-72, and LL-08-75 page 14 of 16 Minor PRD Amendment 1. The proposed minor change to lot boundaries between Lot 2 and Parcel A would not change the number or orientation of any lot. There would be no change in use, intensity or character of development, no increase in coverage by structure, and no impact to traffic circulation. The 175 square feet that would be removed from open space use is not an area used by tenants or the public because of its location on a steep slope. The minor amendment would not, therefore, reduce required open space or tenant use areas. Findings Nos 21, 22, and 23. 2. With a condition requiring the lot line adjustment to be recorded before commencement of grading or building permit issuance, the minor PRD amendment would be consistent with ECDC 20.35.110.A. The significance of development limitation on Lot 2 was not fully appreciated at the time of its approval because the City's critical areas regulations had not yet been adopted The Lorian Woods homeowners' association is in agreement with the proposed amendment. Findings Nos 21, 22, and 23. DECISION Based on the preceding findings and conclusions, the requested height variance, critical area reasonable use variance, and minor PRD amendment related to a proposed single-family residence at 16007 - 7P Place West in Edmonds, Washington are GRANTED, subject to the following conditions: 1. The Applicants must obtain all necessary building permits. 2. The Applicants must comply with all the terms of any future permits, including compliance with all geotechnical recommendations accepted by the City. Development of Lot 2 is further required to comply with the original conditions of approval for the PRD as well as the mitigation measures required by the MDNS issued during PRD review. 3. The amendment to the Lorian Woods CC&Rs allowing eaves to extend into the setback from Lot 1 must be recorded prior to the issuance of building permits. 4. The Applicants or successors in interest must act on the approved variances within one year from the date of approval or the variances shall expire and be null and void, unless the owner files an application for an extension of time before the expiration and the city approves the application. 5. The Applicants shall submit Minor PRD Amendment documents to be recorded to the City of Edmonds' Planning Division for review prior to recording for review and acceptance by City Planning Division Staff prior to recording. 6. The Applicants must record the approved Minor PRD Amendment documents with the Snohomish County Auditor's office.

Any Berson wishing; to file or respond to a request for reconsiderationor an appeal should contact the Planning_ Division of the Development Services Department for further procedural information. REQUEST FOR RECONSIDERATION Section 20.100.010(G) of the Edmonds Community Development Code (ECDC) requires the Hearing Examiner to reconsider his or her decision or. recommendation if a written request is filed within ten (10) working days of the date of the initial decision by any person who attends the public hearing and signs the attendance register and/or presents testimony, or by any person holding an ownership interest in a tract of land which is the subject of such decision or recommendation: The reconsideration request must cite specific references to the findings and/or the criteria contained in the ordinances governing the type. of application being reviewed. APPEALS Chapter 20.105 of the ECDC contains the appeal procedures for Hearing Examiner decisions. Pursuant to Section 20.105.040(A� persons entitled to appeal include (1) the Applicant; (2) anyone who has submitted a written document to the City of Edmonds concerning the application prior to or at the hearing; or (3) anyone testifying on the application at the hearing. Sections 20.105.020(A) requires appeals to be in writing, and state (1) the decision being appealed, the name of the project applicant, and the date of the decision; (2) the name and address of the person (or group) appealing the decision, and his or her interest in the matter, and (3) the reasons why the person appealing believes the decision to be wrong. Pursuant to Section 20.105.020(BI the appeal must be filed with the Director of the Development Services Department within 14 calendar days after the date of the decision being appealed The appeal must be accompanied by any required appeal fee. TI(iVV iE LIIVIITS FOR RECONSIDERATION AND APPEAL The time limits for Reconsideration and Appeal run concurrently. If a request for reconsideration is filed before the time limit for filing an appeal has expired, the time clock for filing an appeal is stopped until a decision on the reconsideration request is completed Once the Hearing Examiner has issued his or her decision on the reconsideration request, the time clock for filing an appeal continues from the point it was stepped: For example, if a reconsideration request is filed on day five of the appeal period, an individual would have nine more days in which to file an appeal after the Hearing Examiner issues his decision on the reconsideration request. LAPSE OF APPROVAL Section 20.85.020(C) of the ECDC states, "[tjhe approved variance must be acted on by the owner within one year from the date of approval or the variance shall expire and be null and void, unless the owner files an application for an extension of time before the expiration and the city approves the application."

The sloughing was, likely. caused by: a combination ' of the natural slope erosion, processes that were occurring prior to the. land being cleared,. the over clearing and disturbance of the top .of,the slope .during: logging, and the temporary stockpiling of erosion control mulch along the top'of the slope.". Lot 3 of Sequoia Ridge is the -Bosch. House. Dec. 167•2001 A.slide,occurred near Lof 2 of'Sequoia Ridge._ This.material impacted the slope above Lot 5.of. Lorian.Woods. This is -discussed in,letters by Landau dated'December`19,,..2001 and GGN dated December 28, 2001. , Landau, is, providing geotechriical oversight services .of developments. for the City of Edmonds. The Landau letter also discusses construction'practices on Lot.3 of Lorian _ "Woods;: the Bosch, House. There is a `concern expressed. that temporary soil stockpiles are to . close to -'the of the slope and that.there.could,be further,slope.failures in the near, future. Rainfall was described by Landau as being,above.:average. "for the preceding months; and heavy for the day preceding the slide.. Sept A 2003, A slide .occurred on Lot.4 of. Sequoia Ridge'- that 'reportedly impacted Lot. 2 of-Lorian' Woods ' and/or the native'growth area 'adjacenf to Lot 2 of L'orian:Woods. This is discussed in a letter by '.Landau dated September 16; 2003. The weather"prior to the.slide`is described'as being.dry. At the. time of the.,slide, the weather was described as, being a heavy rain.. `Further` tension eracking was observed on. Lot. 3 of Sequoia Ridge.. The. tension cracks were in a position. above Lot 5 of Lorian Woods.. Nov. 8.,1004 Terra.Associafes, Inc, excavated two test pits.op Lot,- 2 .of Lorian Woods: "No fresh._deposits,of landslide- debris were. noted on, adjacent to, or above the lot :Feb. 14; 2005 A: slide occurred.on Lot 3 of, Sequoia Ridge'in.the;.area where Landau -had expressed concerns in 2003. This is.disc issed in the:Landau letter dated. February 22, 2005. The'slide does, not.appear. to have damaged the drainage collection system,1A..

J ' Project No T-840' 10 , Page No. 2 Brian.and Cindy Isaacson June 2, 2009 ; From the discussion above, it .appears that there' has -been : an increase_ in slide "activity subsequent- to the development of .the land above.Lots .1, 2, and 5 of Lorian .Woods. This can either be attributed to disturbance- from- the development activity or perhaps to. increased observations of the slope as a result of the' development activities. In any event, none of the direct deposits of.landslide debris have been observed nor reported, to have' directly impacted the envelope of the proposed Isaacson, House.. To mitigate potential impacts ;due to the recent increase in' slope movements, a• catchment ,wall will be placed above the proposed Isaacson residence to control materials that may encroach 'on "the house envelope, in the future. ' Increased stewardship of the "slope "area can be . expected to occur as homeowners perform' maintenance work to preserve property values and -the safety of their. : respective homes`. ' In, -our report for the plat dated 1989, we state that it is our opinion that the return period for the shallow .slides" described above to be on the order•of 10 to 20 years. In addition, our report discusses -that the shallow avalanches and .debris flows "do not commonly reach the lower area where the house is to be located. Slope Cross Section Using survey information .provided by Western Engineers and- soil test borings from our files by others, we developed. the attached .cross section. The.:scheinatic.location of the "cross section is" shown'on Figure 3..' •The. . generalized geologic "section is shown on Figure-4. This,geologic section is consistent with the sections drawn by 'others forthis vicinity. ; The logs for the borings used to construct the�cross'se'ction are.presented in Appendix"A. "Appendix B" is the survey information from Western Engineers showing the. surveyed location of the section Cedar Lod, Accumulated Slope .Sediments and General Slope Restoration - , In our referenced.report dated March 31, 2008' we recommended that the cedar:log.located above the house site in, the common area be removed: This log, has a diameter -of -about three feet and has been "lodged on the slope'for :many years: Prior to, 2006, it does not appear that there was any significant sediment accumulation above the log. Some" of the slide debris from the. 2006 event, has accumulated behind'; uphill of the log." : We have estimated that • . the amount: of soil that. needs to be removed "is'"on the order of 30 cubic yards. -The soil should lie`removed using a low. impact technique. "It does not appear to.be feasible to use'a'trackhoe to remove the soil and the-log..We . recommend "that the contractor use a, vacuum truck to remove the soils... This will limit the. number of ;workers, required, to. clirrib up the slope and will .speed the. removal. of the soil.. The soils should be removed io.'restore the , slope profile in the, area of the log. The, exposed log can then be cut, into smaller'pieces 'and be removed: The -in. . situ .stumps that have been supporting the log should .remain intact on the slope and should riot be physically, removed: A preconstruction meeting should -be held to discuss the contractor's` final plans The slope -above the.proposed "house. should be .cleared of all loose "tree debris, logs, and'dislodged stumps' The= . ; woody rnaterial'can be chipped on -site and, be reused as mulch for erosion control. In situ stumps should not be, removed unless approved for removal by the geotechnical engineer. There is a short steep area immediately - adjacentto the eastern upper property corner that should be regraded to:match adjacent slopes. ,.This shomsteep . area was created, through the removal of a stump during previousclearing activities.: It is estimated that:five cubic yards of soil may need to be removed to reshape this local area'. The excavated materials should.be exported form the site unless it is suitable for reuse as structural fill and will fit in"the stockpile area shown on -the current project plans. Project No T-840-10 .: Page No. • 3 Brian and Cindy Isaacson , Jund- 2, 2009 All work on the slope should be done..iinder the full-time observation, of a representative of the Geotechnical Engineer. Catchment Wall Revisions In our 2008 report, we. presented design criteria for a catchment wall constructed with soldier: piles. Due. to the' projected,costs of the soldier pile -:wall, the project plans now show a cantilever retaining wall designed using the :same catchment wall -and retaining wall foundation criteria:contained in our report. The wall does :not ,have an :access path as shown on.previous drawing's: When sediments :accumulate the wall; they will,*eed.to be removed by hand using.a •wheel •bariow or,through the use of a vacuum truck.... In addition to the catchment wall, the final house plans include concrete walls that are designed as retaining walls that extend' to three feet above grade along the eastern uphill side of the house. .In addition, no door openings'& . Were placed along the uphill side of the house. i Groundwater Level Monitoring We' have reviewed static water..level measurements 'collected by. Landau and by, the City of: Edmonds for piezometer.No. 17. This piezornetdr is located'near.the southwest corner of the lot.:. The Piezometer installation is .discussed. in 'the Landau memo dated. January 24; Z007. The •depths are shown on the. memos_ attached in Appendix,C The data;is: summarized•on Chart 1 in. Appendix C.' The data shows that the static. water level rises _ f.. in the wetter`•winter months and declines:in the dryer surrimer,months. The proposed project should not cause. _ groundwater levels to rise on or'adjacent to the lot: ; We ,understand that the City of Edmonds will continue to moniior the. static water level on a regular basis.. Drainage System_lA We:understand that tlie.Isaacson's'have taken responsibility for the maintenance of Drainage System 1A: :Tfie :. seepage pattern on the .hillside appears to -have changed froin•the time that Drainage System lA was installed. .

There was alight trickle: of water from the line that extended from SDMH .7 towards SDIVIH 6: If, appears that. SDMH� 7 has � been removed during previous clearing.` activities: , We recommend that SDMH 6 be removed and be backfilled with a clean crushed rock.

Brian and Cindy Isaacson . June 2 2009 During site grading, the- remaining pipe that drains SDMH 6 to SDMH. 5 should be removed 'and the trench be backfilled with structural fill. The- discharge ,from SDMH 9, and the actual condition of SDMH .5. should be evaluated during, site grading The: lateral system .to-SDMH 9 is- above=grade for'mostof its extent.'.• -If, the . evaluation indicates that the line should: remain in place,' the pipe should, be replaced with HDPE butt welded pipe:. The diameter of the HDPE pipe does not need to be any larger than four inches and may be placed on the surface in'a mariner consistent-with'the upper. drains being placed for this project: The' CMP between the location of SDMH 5 and CB #D,should•be exposed and be replaced with a 12=inch PVC pipe to connect with the lateral to SDMH 9: To, facilitate mmintenance, either. a new catch -basin. can be installed at the location.of SDMH,5 ora cleanout can be installed at the.elbow that would replace SDMH 5:.` . -The drains shown on Sheet 4 of 6 .of the plans prepared- by Western Engineering are, intended to replace the former system that was placed by the city in the late 1980s.• The use .of flexible pipe on the surface.and surface : collection; pans should facilitate maintenance:. Any damage to the system will be visible and -.repairs can'then be made -without the need, for equipment, or, trenches on the hillside: . Slope Revegetation Pians . The slope revegetation plans should proceed as 'soon as possible following the -removal of the cedar log ;and slope restoration' work'and placement. of.the drainage system described above. Fills Fills of 'up to two' feet will.,be required in local, areas around the .house, to promote drainage. These fills are minimal in nature and will `not decrease the". stability of the -site or adiacent,slopes: 'There will need* to of up. to five feet in. depth to create the landing for_ the entryway stairs and a'fill of up to four feet in depth for the northwestern -edge of the patio. along the back of the house:. -.As shown :on.the civil; plans, .the cut,for the house involves the removal of 450 yards�of soil and the placement of 50 cubic.yards of soil. Thus, there is,a net- loss .of soil: from the site of about 400. cubic yards. The proposed fills.. are' not in a location that .will create slope instability issues. The short 2:4, fill slope along -the north elevation' -of the .house .from .the,fill used. to support the'northwestera corner., of the' patio is: suitable_ for this site and will not lead to slope instability issues.: To address the possible " settlements from the fills used ,to create the -entryway, stairs,. we recommend that the'area be pre'loaded prior to placement of the stairs and.associated walls. Thepreload may consist of Ecology Blocks 'stacked fwo.blocks:high- covering the -footprint of the.proposed;fill:..A's.an alternative, a..tempora"ry stockpile .of backfill.at least six feet, high can•be.placed at, the -entry -fill location.: This. -preload should,remain.in place for at. least four weeks prior to placement -of the walls and fills needed to support.the lower portion of the entryway.stairs: "A temporary fill stockpile area, adjacent to the southwest corner of the lot is permissible., :This is below the toe of the eastem,slope''and, well. away fromthe slope that is present on the western margin of the plat of Lorian Woods. , It -is. our opinion that the use of the area for a temporary stockpile not; to exceed 50_cubic yards will not decrease the stability of the site slopes on' or, adjacent: to Lot 2. Unless approved by the geotechnical engineer, the . stockpiled soils must be completely rem oved.by.the beginning of the ,wet season on October. 1. _ Project No T-840-10 .

Subsidence 'and Landslide Hazard Area, as defined by Edmonds Community 'Development Code Chapter. 19.10. Our previous" study 'outlines •the, hazards associated with ' development ..on the. property. The hazards ,outlined in. the referenced 2007 Landau Associates study are. - consistent with the hazards outlined in our previous study. In the preparation of this.report, we have 'reviewed the referenced 200TLandau Report. Based on our., experience on -site and our observations in, the neighborhood, we', - have identified the site as being within. Zone B' as shown on Figure l..of the 2007 Landau report.: The slope immediately east and uphill from the building site lies within Zone C and D. The risk,'of earth movement in the 2007 Landau Report for Zone B consists of: .:Encroaching ,landslide debris originating upslope • : Reactivation of landslide debris causing ground failure and movement • Landsides, in ground that' has riot previously_ failed Page No. •3 . i, March 31 `2008 Project No: T=840-10 Based on our observations on' the plat since 1988, we concur -that the first, two risks of ground movement are '- ossible. • The entire site .consists .of earth that has ,moved'at some time in the ast; so the third.risk is not P P - applicable on this site., We analyzed the probability. of landsliding and movement, for our report for the plat of - Lorian Woods., We identified the hazards of earih movement in the area up`slope •from the buildinglot as.being,5 percent in a'25=year; period. We identified the,risk_of movement within the building lot as being 12 percent .in "a 25-year period. Development of the, lot involves' an element''of risk .that ,the homeowner must accept.. Stewardship of the vegetation and drainage'facilities onthe•site -will be an important element of the project'over the life of the. house. Encroaching.Landside Debris Originating'Upslope We have made periodic visits to.the plat forrgeotechnical.purposes over the past 20 years. Only one significant, episode, of.movement, has been documented to, have _occurred on or., adjacent ,to the site in that period. This. movement is the slope failure. that occurred in the winter of 2005/2006 along the upper edge of the slope above the:Plat of Lorian Woods. ,This.failure occurred immediately adjacent to a house: built in about 2000. The slope failure resulted in the retreat of'. the top'of.the slope by approximately five'to ten feet., We. understandthat the previous occupant of the house has moved,'the house is vacant, and that the. property has not been fully evaluated ' by: a geotechnical, engineer. The actual cause. of the slope faila're.has not be'en-determined. The:2005/2006. ' failure resembled .a toppling or calving of the upper 10 to 15 feet of the slope. All of the soil was either caught - behind a cedar log tliat is wedged behind a .pair of stumps. or it mounded up on the upper portion -of the slope immediately northeast of the building lot. ;The soils'froin this failure that encroached onto the building'lot and tproposed building envelope were eroded by running: water and redeposited as sediment lower on the site. Based. on our observations on=site, we estimate the `volume of failed material,as being about 40 to 50.cubic yards. , In the, fall of 2007, the older. trees on'theslope 'above :the lot were removed: A report, was prepared by. Urban - . Foresters .that cataloged the diseased trees on the slope. We expressed our concurrence with the -tree management and replanting 'report prepared 'by Urban foresters dated March .4,. 2006. - A significant -risk that. occurs during' landslides is.the action of the trees., The trees on. the site that were e found to.be diseased or,dama d�have been . g removed: The restoration -of .the trees will .result in trees that provide a canopy, but,have .smaller trunks, to reduce . ' the potential for damage from trees that may become'involved in earth, movements. The top of the* slope east and above the site -may be regarded as a' -bluff top..: Based on -the observations'. '. documented in this report, we estimate that the.re'treat of the top of the bluff may be; on the order of 10. feet per 50-year�period..Unless the, uphill neighbor -provides mitigation for the recent bluff top retreat, further retreat of the bluff will occur.. This mode of slope failure can be mitigated with a catchment wall' above. the proposed house to stop the landslide debris from impacting the house: Regular removal .of calved and eroded soils will, be re uired-on the slope above the house over the life:of the structure. We would ex ect that thesis . 9 k of this threat would be reduced in the future b im rovetnents on the:d h illpropert � . - • Y. P P _ Y .. , Provided' the recommendations contained,,iri- this report are incorporated. into site development plans, it,is 'our• opinion that the development will riot,40crease the -risk of instability or the rate of bluff top retreat above?the site. . Page No 4 _ March 31, 2008 Project No: T-840-10 ' Reactivation of Landslide Debris Causing. Ground Failure and Movement In regards, to, the risk of movement,of previously failed materials, the. second, mode ' failure in the bullet list above, should be noted. that the house on the lotimmediately; south and downhill, frorri the. site has been present' since,1964.dnd- has not received levels of damage that have'rendered `it unusable. Beneath the house, immediately east, O.Nhe site are houses on Tax ,Lots 005:13105800500 and.00100 that have beer present.since'1934: Both, of , " these ,houses are, inhabited.'. While this .does not indicate the "lack .of movement; it does -illustrate that the magnitudes; of movements that have occurred have been, manageable or are within the tolerances of. the I .I7. structures"•foundations.'' .. 1 ' To mitigate against possible`shifting within the landslide mass,' the house will be'built on a rigid g'rid.foundation. It. is beyond the scope of construction on a single lot to mitigate the possible :deep. -sealed movements_that could .'' occur into nto the future. If oundwater levels are found to rise in the. ermanent cit iezometers neighborhood the nei h .. � • ,. -permanent , . YP would need. to as a group" install drainage facilities such as horizontal wells to maintain the, water table at or ' below the current levels'. Provided the rec m o rnendations contained in, this rare." . s e ort _,. p -incorporated into, site development plans,. it is our ; opinion that the development will not increase the risk of instability on the site or, on adjacent properties., 4.2 Seismic , Based on. the,Edmond Municipal Code •23.80.020, the site is'within a seismic. hazard area. This. classification is.. due to the, presence of potentially liquefiabfe soils "beneath the site. Our review -of maps showing current'faults shows that there"are no known or suspected faults as'being within three miles -of the site. Current mapping. shows that the closest faults are the South Whidbey` faults, that extend diagonally,..across south Whidbey Island. and extend: through the-Mukilteo area north of the site. This mapping is based on infofffi tiori in the Map and Data for Quaternary Faults and Folds in Washington State prepared by the USGS,. open'file report.03- 428. " ' Based.. on-, our knowledge of 'soil conditions and local geology, per Chapter 16 of the 2006 International Building Code (IBC), site class "B" `should be:used in the project's structural design. Liquefaction is a phenomenon where, there is a reduction. or complete loss rof soil strength due to:an increase in ' water pressure induced by vibrations..',Liquefaction mainlyaffectsgeologically. recent deposits of fine-grained ` sands that -are below the groundwater table. Soils of this nature derive. their strength from interanufar friction. The generated water pressure or pore, .pressure essentially separates 'the soil. grains ,.and :eliminates this intergranular, friction, thus eliminating the soil's.strength.:. Based on ' our knowledge of, the , soil . and groundwater; conditions, it is our 'opinion. that there is, a risk for liquefaction 'to occur'at:this site, during-;an'earthquake: %The risk from' rom-liquefaction would exhibit itself 'as differential settlements in the building. The.proposed building will be built. on id'id a riggrfoundation to mitigate for possible lateral _shiftsAdue,to land subsidence from landsliding..This, mitigation, will also'mitigate against the. ~ risk of foundation'settlement due to liquefaction.

This classification is based on slope inclinationI,and the presence of •seepage on the site. The site:,has' had tree removal performed in accordance with a'free removal plan; prepared by others:, The sitewas.mulched following.the'-removal of the trees.. -We have not observed ,any signs. of erosion. related issues-on`the site over.the• course of the winter of 2007/2008 including a site visit following the, heavy rains of the: first week of December 2007. - Development of the site will include a temporary erosion and sediment control -plan.. Erosion will be managed through the con'structiori. period using -established BMPs:. . 5.0 DISCUSSION`AND RECOMMENDATIONS 5.1 General, As noted earlier., the site is"in a mapped landslide hazard area Relative risks, of slope movement are discussed in, ; our --June ;61 1989, reportand in the 2007 Landau-,Asso6a' tes Summary Report. Provided the owner is,willing, to ' accept the risks, associated with slope instability at,tfie'site, in our opinion, the -site conditions are suitable for the :proposed construction.,: We fe' commend the structure 'be supported on a mat/raft' foundation, ^bearing . on the existing.colluvial soils or on structural fill placed above these colluvial soils:. ' ' A surface Swale should`be constructed along the uphill side of the house' above the proposed landslide.catchmeni wall...' The, swale should span the entire -width of the building area 'and- discharge ,into the .Plat,'torm system: The catchment wall indicated on the ,drawings should conform to the design recommendations outlined on Figure 4. The site soils contain significant amount of fines and will be difficult to compactas structural fill when too wet. :The ability, to, use native soil from site excavations as structural fill will,depend 'on the soil's moisture content and the prevailing.. weatherconditions of the time of construction. 'If grading activities take=place during the' winter season, the owner should be, prepared to import free=draining granular ,maferial for .use, .as. structural `fill . and backfill., No fill.may:be placed�that will raise existing site grades., All'soils excavated from ahissite and not used , as backfill must -be removed from the site.. ; The .large cedar log and accumulated- soils along the upper' slope should. be- removed. ,.,This; work will need to -be done using either'by hand or light weight equipment.., Thesoils and log should be removed from the' site.' - Detailed recommendations regarding these issues and other geotechnical design! considerations are rovided, in . the following sections -of this. report.

If.excessive I' soft areas 'are ;observed and ,cannot;be stabilized in place Eby compaction; the affected soils should be 'excavated and:removed- to firm bearing- and grade restored with new structural fill: If the depth. of excavation to "remove unstable soils'is excessive, use .of a„geot6xtile reinforcing/separation -fabric, such 'as Mirafi 500X' or equivalent; can-bei considered in conjunction ,with" ciean granular structural fill. Our'experience.has. shown that;' . '"in general, a minimum of 18 inches of a clean; granular structural fill `over the geotextile`fabric should'establish a stable bearing surface . Our study, indicates that the colluvial soils'contairi.a significant,percentage of fines (silt -arid clay -sized particles),: - which makes'. them difficult to .compact as structural fill if they 'are too wet or too dry... Accordingly, the•ability to, ' use native soils from. site,excavations,as structu'raL fill will de end on.their'moisture content and theprevailing- p weather condition's when site grading activities take place: \ If .grading activities: are' planned during the wet ,winter months; ; or if they. are initiated during the; summer and extend into fall and winter, the owner should be prepared to.import wet 'weather"structural fill.' For this purpose, we recommend importing a clean,granular soil that meets the following`.grading requirements: _V.S..

Immediately below slab -on -grade floors;'we recommend placing afour-inch thick capillary break layer of clean, free -draining,,. coarse sand, or fine gravel thaf has less than -three percent passing the No: 200 sieve.' This material P p g will reduce the :potential for' upward capillary -movement of water through the underlying •soil and subsequent wetting of the floor slabs.' The;. capillary, .break, layer 'will not prevent moisture intrusion' through the slab caused_ by water,. -vapor transmission. Where moisture by. vapor transmission isundesirable, such as ',covered floor areas, a common practice is to place a durable, plastic membrane.onthe capillary break,layer'and'.then:cover'the.,membrane with 'a layer, of clean sand or fine gravel to, protect it from damage, during construction; and to aid iri uniform curing of the concrete slab. It should, be noted that if the sand or gravel layer overlying the membrane is,saturated•prior,to ' pouring'the slab, it -will be ineffective in.,assisting uniform curing, of,'the-slab and'can actually serve as a water supply, for .moisture transmission through the slab and, potentially affect floor coverings. _Therefore;. in our opinion, covering the membrane with a layer of -sand or gravel should be* avoided if floor slab construction occurs during the wet winter months. and the layer cannot be effectively drained. , -Other methods Are.. available' for preventing or,.reducing watervapor transrriission .through,' the slab:. We recommend consulting with a building envelopespecialist 'or. contractor for additional Assistance -regarding this ; ,P g g issue. 5.6 Retaining, Walls' . The magnitude of earth pressure development -on. below=grade walls, such as basement walls,'^will partly depend on the quality of the_ wall backfill., We recommend placing and compacting wall backfill as structural fill... Wall 'backfill below structurally loaded areas;'suc' h as pavements •or floor slabs, should be compacted to a,minimum of 95 ercent `of its ' maximum dr . density,: as 'determined b , A T p y y, y ASTM Test -Designation'D-698 (Standard Proctor): In, unimproved areas, the relative'compaction'can be reduced to.90 percent: 'To guard against, hydrostatic, pressure development, drainage must be installed behind the wall., Atypical wall drainage detail is shown on Figure 3: 'With wall backfill placed and compacted as recommended and drainage properly installed, unrestrained .walls can be designed for an active. earth piessure'equivalent to a'fluid weighing 35 pcf.: For restrained :walls, an,additional ' uniform lateral pressure- of ,100 psf, should be :included: For evaluation . of below -grade walls under seismic loading; an additional "uniform load -equal to. 8H psf; ,where His. the' below -grade height of the wall. can' be used: These: values assume a horizontal backfill condition and thavrio other surcharge loading (such as traffic; sloping . embankments, or adjacent buildings) will act .on the -wall. such conditions exist the imposed loadin must be g: _ � .P g • included in the 'wall•design::,Friction at the base,of the wall' foundation and passive earth 'pressure will provide resistance to. these. lateral Loads.

' Any, soil or' sediments` that accumulate above the catchment wall will need to be fully .removed in a timely manner-Ne recommend that removal be planned to occur -within orie'to two weeks of d6pogition.N All soils, from ' above the wall,will'need to be�disposed.of off site , 5.8 ' •Drainage , Surf ace Final'exterior grades should promote free•'and,positive`drainage'away from the building area.,,•We'recommend 1. ,. providing a , gradient of at least three percent for `a iiinimum, distance of ten feet from the building 'perimeter, except in paved locations. In paved'locations,:a minimum gradient of.two percent should be provided, unless. ' provisions are included for collection and disposal of surface water adjacent to the structure. All downspout drains 'need to'.be collected%in tightlines and.be.routed to the•plat storm drainage system: We recommend the use .of rigid pipe for. all tightlines. Cleanups' should be provided, every 20 feet to facilitate ' maintainace of the drains. All downspouts.and gutters should be kept clearand free.flowing at all times. To prevent surface, water flowing off the,adjacent, hillside from impacting foundations, we recommend installing ;. a surface swale along the uphill side of the catchment wall., The swale should -extend the entire'width-of the wall and convey surface. water 'to, an, appropriate point of controlled discharge into the. lat stormwater. system located in -the street below the Site. The collected surface water should'not be discharged into the existing slope drainage system currently operating along the south side of the building site. •A surface seepage collection system is, being designed by Western Engineers. - The -system :will replace the upper, ' ' portion .of the former City of Edmonds seepage' collection system that was damaged in the, previous .earth ..movements. The new system will rely on the'`use of .surface collection troughs and -flexible HDPE collection pipes: The use of surface pipes will facilitate maintenance and will allow flexibility .of the collection. system., The ' surface drainage `system should be maintained -.'on' a regular - basis:' . This .will' include shifting. or adding troughs. All surface seepage and, runoff collected on-site,inust be routed. to the site •storm drainage. system. If' ` 'water -features are included iwthe final site .fayou_ t'-along the' house, the channels to carry surface. water must be lined 'with a welded HDPE membrane.

On February 27, 2008, we supplemented this data by drilling one 40-foot boring. The approximate test pit locations are shown on Figure 2. The Test Pit Logs and Boring Logs are presented on Figures A-2 and A-3. A geotechnical engineer from our office conducted the field exploration, maintained a log of each test pit, classified the soils encountered, collected representative soil samples, and observed pertinent site features. Our representative classified the soil conditions encountered, maintained a log of each test boring, obtained representative soil samples, and recorded water levels observed during drilling. During drilling, soil samples were obtained in general accordance with ASTM Test Designation D-1586. Using this procedure, a 2-inch (outside diameter) split barrel sampler is driven into the ground 18 inches using a 140-pound hammer free falling a height of 30 inches. The number of blows required to drive the sampler 12 inches after an initial 6-inch set is referred to as the Standard Penetration Resistance value or N value. This is an index related to the consistency of cohesive soils and relative density of cohesionless materials. N values obtained for each sampling interval are recorded on the Boring Logs, Figure A-3. All soil samples were visually classified in accordance with the Unified Soil Classification System (USCS) described on Figure A-1. Representative soil samples obtained from the test pits and boring were placed in sealed containers and taken to our laboratory for further examination and testing. The moisture content of each sample was measured and is reported on the Test Pit Logs and Boring Logs. Grain size analyses were performed on two samples. The results are shown on Figure A-4.

E., Assistant City Engineer City of Edmonds Development Services Department, Engineering Division FROM: Dennis R. Stettler, P.E. DATE: January 24, 2007 RE: PIEZOMET.ER INSTALLATION AND DRAINAGE RECOMMENDATIONS LORIAN WOODS SUBDIVISION EDMONDS, WASHiINGTON INTRODUCTION AND PROJECT BACKGROUND This technical memorandum presents the results of a piezometer installation within a portion of ' the Lorian Woods Subdivision and an assessment of the groundwater conditions with respect to proposed modifications to the dT-Wuage system. The purpose of these services was to evaluate the current groundwater conditions and to provide consultation to the City of Edmonds (City) related to the design ' and construction of a replacement drainage system. The piezometer was installed on the paved shoulder of 73"' Place West, about 250 f3 south of the intersection of 73T4 Place West and North Meadowdale Beach Road. The piezometer location is shown on the Site and Exploration Plan; Figure L The Lorian Woods Subdivision is within the designated North Edmonds Earth Subsidence and Landslide Hazard Area, and control of surface water and groundwater in ' the area improves overall slope stability. 1 Springs and groundwater seepage from the steep bluff on the east side of the Lorian Woods subdivision had been collected by a surface water collection system (Drainage System I A) constricted at the base of the bluff by the City as a part of Local Improvement District (LID) drainage improvements completed -in the 1980s. Landslides, originating on the bluff above the drainage collection system on and above Lot 2 and the adjacent common area to the south of Lot 2 in the Lorian Woods Subdivision, have destroyed or damaged portions of the drainage collection system. The landslides are the result of a very steep bluff face and the presence of seepage on the bluff. The landslides are occurring above the drainage system and are not related to the presence or function of the drainage system (the drainage system is intended to improve slope stability conditions below the drainage system). The recurring landslides from above the drainage system, the presence of landslide debris, and leaning trees on the steep slope have created a hazardous work area for City workers to repair or replace the drainage system in its original location. The City is considering alternate drainage systems as a replacement for the existing system (Drainage System IA). This could include working with the property 130 2nd Avenue South .

The private drainage system would then feed into the City system. Previous conceptual surface water drainage systems for this location have included consideration of a shallow groundwater drainage system. If shallow groundwater is present, it would be appropriate to construct a subsurface drainage component into the new drainage system to intercept groundwater and convey it to the City collection system. However, limited groundwater information was available to know the depth of groundwater near the proposed surface water drainage system, and the City requested that Landau Associates install a piezometer at this location in order to measure the groundwater Ievel. SCOPE OF SERVICES Landau Associates' scope of services included installation of a piezometer to monitor ' groundwater levels and consultation related to the design and construction of a replacement drainage system. Our services were provided in accordance with Task Order No. 06-05 under the On -Call Geotechnical Engineering Services Agreement between the City of Edmonds and Landau Associates. The scope of services included: it 1 1 J I 1 • Drilling a boring to a depth of about 20 fl and installing a piezometer using a licensed well driller under subcontract to Landau Associates to monitor groundwater levels. • Coordinating the boring and piezometer installation by a Landau Associates geotechnical engineer, including locating the boring, checking the boring location for buried utilities using the one -call public utility locate system, monitoring the drilling of the boringi preparing a log of the boring noting the soil and groundwater conditions, and observing the installation of the piezometer: • Monitoring the groundwater level in the piezometer three times after completion of the piezometer installation. After that time, the piezometer can be included with the system of other piezorrieters in the North Edmonds Earth Subsidence and Landslide Hazard Area that are monitored by City personnel. • Preparing this technical memorandum that provides a log of the boring and monitoring well, the installation procedures, and the results of groundwater monitoring. • Providing additional consultation related to design and construction of drainage measures. FIELD EXPLORATIONS Subsurface'6onditions at the project site were explored on October 2, 2006. The exploration Program consisted of advancing and sampling one exploratory boring and installing a piezometer (P-17) at the approximate location illustrated on the Site and Exploration Plan, Figure 1. The exploratory boring 0124J07X""datalPi*CfSW7411iMZOtWIAMPlozolneulWan Im.doe 2 DRAFT 17/2007 1.5:21 FAX 425 778 4499 HANSEN DICLAUGALIN Q 004 was advanced to a depth of about 21.5 R below the existing ground surface (BGS) using hollow -stem auger drilling techniques. Holocene Drilling, Inc. of Graham, Washington, under subcontract to Landau Associates, advanced the boring. The exploration was located approximately in the field by hand taping from existing physical features and referenced to a site map provided by the City. The ground surface elevation at the exploratory boring location was interpreted from the elevation contours on the site map provided by the City (which is referenced to an arbitrary benchmark). The field exploration program was coordinated and monitored by a Landau Associates geoteclunical engineer who. also obtained representative soil samples, maintained a detailed record of the subsurface soil and groundwater conditions, and described the soil encountered by visual and textural examination. Each representative soil type observed in our exploratory boring was described using die soil classification system shown on Figure 2, in general accordance with American Society for Testing and Materials (ASTM) D2488, Standard Reconrrnended Practice for Description of Soils (Visual -Manual Procedure). A summary log of the exploratory boring is presented on Figure 3. This log represents Landau Associates' interpretation of subsurface conditions identificd during the field exploration program. The stratigraphic contacts shown on the summary log represent the approximate boundaries between soil types; actual transitions may be more gradual. The soil and groundwater conditions depicted on the summary log are only for the specific date and location reported, therefore, are not necessarily representative of other locations and times. Disturbed samples of the soil encountered in the exploratory boring were obtained at selected intervals using a L$-inch inside -.diameter Standard Penetration Test split -spoon sampler. The sampler was driven up to 18 inches into the undisturbed soil ahead of the auger with a 1404b hammer falling a distance of approximately 30 inches. The number of blows required to drive the sampler for the final 12 inches of soil penetration, or part thereof, is noted on the boring log, adjacent to the appropriate sample notation. Samples collected in this manner were taken to our laboratory for further examination and testing. Upon completion of drilling and sampling, a piezometer consisting of a 2-inch diameter, schedule 20 PVC well casing with a 10 ft length of 0.010 inch machine slotted well screen was installed. Sand pack was installed around the screen section and bentonite chips were installed above the screened section extending up to the approximate existing grade. The 'top of the piezometer was fitted with a monument cover installed flush with the pavement and the pavement patched with concrete. The borehole and piezometer (well) was installed in general accordance with the requirements of Washington Administrative Code'(WAC) 173-160. 0124107 dEdmtlAhMrajpq�E10741115WZ01WIPYR\PicZOlpyl�llllun Im.dac 3 I 12/17/2007 15:21 TAX 425 778 4499 HANSEN AICLAUGHLIN 9 005 1 1 1 1 1 1 1 1 1 1 1 1 1 SOIL AND GROUNDWATER CONDITIONS Soil that was interpreted to be landslide debris was disclosed for the full depth of the boring (21.5 BGS). This condition was consistent with our expectations given the geologic history.and the results of previous- explorations in the area. The soil included. sandy clayey silt, fine to medium sand, silty fine sand, and fine sandy silt. Occasional wood fragments and or were encountered in the boring. The soil generally ranged from very loose to loose and soft to stiff. Groundwater was encountered at a depth of 12 ft BGS at the time of drilling on October 2, 2006. Groundwater levels often need to stabilize after drilling and the water level at the time of drilling is probably not as accurate as subsequent measurements. Three groundwater level readings were obtained between December 15, 2006 and January 1.8, 2007 and ranged from 5.5 to 6.6 ft BGS: The October reading could be due to a relatively low groundwater level following a relatively dry summer and early fall, or it could represent a groundwater level that had not fully stabilized at the time of the groundwater reading. November was an unusually wet month with significantly above normal precipitation. December and January represent relatively typical wet winter months. The groundwater readings taken in December; 2006 and January, 2007 probably represent relatively typical winter groundwater levels at this location. Groundwater levels can be expected to fluctuate according to the seasonal level of precipitation, the influence of the degree of surface water runoff and infiltration, and other factors. The, groundwater levels recorded at Piezometer P-17 are summarized in the table below. Piezometer P-17 can be added to the network of piezometers (Piezometers P-1 through P-16) in the North Edmonds area that are monitored by the City.

This ' seepage condition results in areas of standing and flowing water and wet surficial soil conditions on Lot 2 and adjacent areas above (to the east of) 73'd Place West. A significant portion of the seepage appears to be flowing acrossi the ground surface and is being collected in an informal manner along the east edge of the 73`d Place West pavement and discharged into a catch basin. An unknown amount of this 1 11 I Ll groundwater seepage infiltrates back into the ground as it travels between its point of emergence as a spring on or near the base of the bluff and its present collection point at the edge of the road. It is desirable to intercept this seepage further upslope. This will both limit the amount of infiltration back into the landslide mass, as well as improve the surficial, wet conditions on Lot 2 and adjacent areas. However, damage to the existing Drainage System IA and the difficulty in replacing and maintaining such a system with City maintenance personnel is problematic. We understand that the owner of Lot 2 is considering the installation and maintenance of surface drainage provisions that would intercept the groundwater seepage and the related surface water flow and convey it to, the City's storm drain system. This approach has several advantages. The seepage collection system can be designed by the property owner to facilitate future development of Lot 2. Maintenance of such a system occurring on private property is best accomplished by the property owner. In addition to the benefits to Lot 2, such a system would reduce the amount of surface water infiltration back into the landslide mass and thus provide an effective replacement for the function of Drainage System 1A. Landau Associates previously considered drainage improvements in this portion of the Lorian Woods subdivision to replace the general function of the City -installed drainage system that was located near the base of the bluff and that has repeatedly been damaged by upslope landslides. One approach considered was to install a.subsurface groundwater drainage trench along the easterly edge of 73'd Place West to intercept suspected shallow groundwater flow. Given the typically wet surficial soil conditions on Lot 2'and adjacent areas, it was thought that the groundwater level may be very shallow at the location of the street and there could be benefits from the installation of a subsurface drainage trench (such as a gravel -filled trench with a perforated pipe that would drain to the downhill catch basin). The depth of any subsurface drainage system would be limited by the elevation of the downstream catch basin manholes (i.e., to allow a gravity drainage system). However, information on the actual depth of groundwater at this location was not available until thw installation of the piezometer under this current study. The available information suggests that the winter groundwater level is presently on the order, of 6 ft BGS at the piezometer location. The groundwater level could fluctuate and we recommend that the City continue with groundwater depth measurements at Piezometer P47 in order to assess longer -term OlaV07 41EtlmdaW4p'ojgUel074ti1G1020�W1pi(i�PimiWNbD R—A— F T 5 ' 12/.17/2007 15:22 PAX 425 778 4499 HANSEN AICLAUGHLIN Q007 conditions. Given the limitations on the probable depth of any subsurface drainage system along 73'd Place West, to allow gravity drainage and the current depth of the groundwater, it appears 'that a subsurface drainage system along 73ta Place West may be of limited benefit. In our opinion, greater benefit would be achieved by allowing the owner of Lot 2 to install and maintain improved surface water interception provisions on Lot 2 and adjacent common areas of the Lorian Woods Subdivision and conveying the collected water to the City storm drain system. We suggest monitoring the groundwater level in Piezometer P-17 before and after any drainage improvements upslope and then reassess whether drainage improvements in the street are warranted. I We appreciate this opportunity to be of services to the City on this project. Please call if you have any questions regarding this technical memorandum or if we can be of further assistance.

Dear Mr: and Mrs: Isaacson: As.requested, Terra Associates; Inc. (Terra) has provided geotechnical engineering services .during.construction of the,subject project. We have provided consultation services during the planning,.design; and permitting phases of this project. " The "referenced report and letters contain our recommendations and. discussion of the proj ect. The purpose of our work was —to verify, that the geotechnical elements of the project design have been'completed ' in accordance with.recommendations outlined in.our geotechnicaLreport for the project. Our work was provided • with periodic site • visit's'coordinated with- your, contractor, Mr.. Jim Arnold.' -We -have previously submitted our 'field 'observations in memos that were sent to you, the contractor, and the City of Edmonds. STREET .

Soils (IBC 1704.7) ' The special inspections were conducted to verify compliance with,the, geotechnical recommendations in our referenced report and letters for the :project that, satisfy the requirements of IBC 1802 and the City of Edmonds requirements. • 2. Soil Bearing Verification Terramade periodic site visits during construction. Representatives of Terra Associates verified adequate bearing for the• foundations within the house footprint and for the upper catchment ;wall prior jo placement of concrete' Adequate bearing was observed in the footing excavations for an allowable bearing pressure of 1,500 pounds per.square foot:, , ' 3. ,Structural Fill Placement and,, Compaction/Placement Terra observed the placement of structural, fill within the footprint of the house, along the eastern margin of the house for the foundation of the catchment. wall,. and. behind the catchment mall. The lower -level basement wall was backfilled with site material compacted in place: Compaction testing and observations during fill placement indicated that adequate compaction was achieved. ' The upper basement wall. along the east margin.of the house'.was backfilled with crushed'rock chips that were compacted in place with a vibratory sled compactor. The upper catchment`wall .was backfilled with clean sand and compacted in placewith a vibratory sled compactor. ',These upper two walls were backfilled using a conveyer -belt boom truck to place material above.the house footprint. ;The backfill for ' the two upper walls consisted of free draining soils: 4. Foundation and Site Drains/Footing Drains . We, observed that • perforated . footin • drains- and a se crate ti htline for roof downs' out drains were P g. P g P . placed.' We also observed that the basement walls were provided with a drainage board manufactured.by Delta. Based on our, observations, the subsurface drains .and downspout tightlines were placed in accordance with our recommendations and the project plans. We observed that the upper seepage zones were --controlled during construction to reduce_ impacts on the area cleared , for construction : from, the accumulated seepage. The permanent site, drainage features include a swale along the top of the catchment' wall with two yard drains to collect_ surface runoff, the upper drainage network,.yard: drains in the' patio. area behind the house, and tightlines for the downspouts. -All elements of the drainage system will need to,be maintained overtime. This includes keeping gutters clear of.debris. Project No. T- 840 ,11 Page No. 2 Cindy Brian and C y Is June 4, 2012 ' 5. General Site Monitoring During Wet Weather.Construction ' We made periodic'site.visits during periods of time that site excavation or backfill operations were under. way. We observed that site activities did not create any site stability oferosion issues. We observed that visqueen was used to prevent erosion from precipitation'. During our -site visit, we did not observe. any ' ' off -site transport of sediments. 6. Temporary Erosion Control We made periodic site visits during eriods•of time that site excavation or backfill'o erationswere under p gP P . , way. We observed that site activities did not, create anyerosion issues.. Following our site visit on January 23, 2012. following a snow -melt -and rain event, erosion control observations were taken over by Mr. Jim Arnold..' No significant earthwork activities took place in the balance of the wet season: 7. Final Erosion Control ' Final erosion:. control will be complete with .the final re -vegetation plans. We have observed that the areas` cleared in the past work on -site prior to 20.11 � have been successfully re -vegetated. We have observed that the area disturbed for 'construction" in 2011/2012 have had plants placed to reestablish erosion control. These plants will need .to be maintained through the summer drought using hand, irrigation. We do -not recommend the installation of 'a dedicated irrigation' system.

The mass excavation for the house is proceeding. The sub grade is being left one to two feet above final grade. Excavated soils are being removed from the site. The soils consist primarily of silts with some pockets of silty sands. There is some wood debris within the native soils. Cuts of up to 6 feet have been made, no seepage was present. Temporary cuts appear to be stable up to four feet in height for the vertical segment. We discussed the need to make cuts that will be WISHA compliant. At the southeast corner of the house it may be needed to use Ecology blocks to support the temporary cut. E blocks should be no higher than two high. The blocks can be dedicated to the backfill. The seepage collections system on the hill above the house is controlling most of the seepage. Some light surface flows persist above the house. It is OK to re- establish the surface swale on the dozer trail immediately above the house. The surface runoff from the swale needs to be directed away from the house into suitable discharge areas. The TESC fencing along the lower edge of the site is intact. A quarry spall entrance has been established. No off site flow of water was observed. TESC appears suitable for the existing conditions. The foundation forming is planned to start on Wednesday Aug 27th. The soils appear to be suitable for keyway construction. The foundation crew will need to exercise care to preserve the keyway during steel placement. Work should proceed in a timely basis.

The mass excavation for the house is proceeding. I had postponed a routine weekly meeting with Jim Arnold at 10 am for this date and we rescheduled it for the 28`" at 10 AM. Brett called at about l l and reported that he had encountered seepage in the stair area excavation. I visited the site to observe the seepage. I recommended that the seepage be controlled with a sump and a pump to see if it is just a pocket of water. I also reviewed the exposed cut at the east side of the garage. It appears that there is sufficient room to cut it back to at least a 1:1, a single high eblock wall can be placed at the toe of the cut to reduce the horizontal extent of the open cut. The eblocks can be left in place in the backfill if they do not interfere with keyways or other construction elements. Brett and I discussed the use of native soils for backfill. The sandy site soils would be suitable for use as wall backfill as long as the walls have been provided with drainage panels such as mira drains. TESC measures appear to be suitable. No off site sediment or water flow observed. Chuck Lie City of Edmonds Copies to: Brian and Cindy Isaacson By.

I recommended the use of the sump to see if it was a pocket of water that once removed would not re occur during the construction period. if a trench is used, I recommended that the trench be backfilled with crushed rock such as the stockpile of pea gravel sized crushed rock that Brett had imported and stockpiled at the driveway area. No pipe would be needed in the trench. The trench should be as deep as possible to capture water from keyways. The same crushed rock could be placed at the base of keyways, no pipes should be placed in the keyways. This crushed rock could also be used to provide a working surface on the bearing surfaces of footings if needed. The stability of the sidewalls of the keyways are the important element. Observation of the seepage conditions will need to continue to evaluate options for keyway construction in the lower areas of the lower floor where seepage has been observed. Spoils from the excavation continue to be exported. A stockpile of soils is present for use in backfill. TESC measures appear to be suitable. No off site sediment or water flow observed.

This is the crawlspace area that will be used for storage. Suitable bearing conditions were observed. Jim will have rebar stubbed out to the grade beams that support the deck area. The deck foundations are covered by a stockpile of soils at this time. The walls at the east side of the garage are having steel placed. Backfill for the east walls of the garage and storage area should be placed as soon as allowed by the structural - engineer. The backfill will need to be placed in lifts and compacted'as described in our report to provide support for the eastern perimeter footings. A sample of the stockpile south of the house was obtained for a sieve analysis to evaluate compatibility, of the soils with the proposed Delta drainage board. The footing memo for today is attached. The footing is scheduled to be placed on Friday Sept 9. TESC measures appear to be suitable. No off site sediment or water flow observed. The weather conditions will change later this month.

Writer was on site at mid day to observe excavation progress. The northern half of the keyway has been excavated and has been both sloped back and provided with temporary shoring consisting of wood panels. The excavation is being pumped with a sump pump. The wood panels do not provide safe working space for crew but will help maintain the shape of the keyway. The structural engineer advised Brian and Jim that extra concrete can be placed in the keyway area to fill caved areas. Provided no further caving occurs, the northern half can be filled as is once the steel gets placed. The southern half of the key had not been excavated yet. Brian reported that the concrete crew would be on site at 9 am to set steel and pour concrete. Chuck Lie City of Edmonds.

The northern half of the keyway has been excavated and has been both sloped back and provided with temporary shoring consisting of wood panels. The excavation is being pitmped,with a sump pump. The southern key was being excavated and was starting to cave, I advised the excavator to speak with Jim before proceed to far with the keyway with no concrete crew on site. I spoke with Jim as I left the site he reported that the concrete was scheduled for about 1 pm. Writer returned at 1200. Jim and Brian were on site. The concrete crew was arriving as I was on site. The southern half of the key way was being excavated while I was on site. Some light caving occurred and was removed while I was present. The soils exposed between the key way and the compacted crushed rock backfill for the house appear suitable for the support of the patio/footing as planned. Jim asked dif he could do two pours on the patio slab thickness, the possible cold join in the patio would need'to be discussed with the structural engineer. Brian and I walked up the slope. There is a tree that has fallen on the slope from tree cutting. I advised Brian to remove the tree and keep the slope accessible and visible for observations throughout the time he lives in his house. We'discussed the need for the surface Swale along the back of the catchment wall. This is on the plans. and will need -to be maintained over time. The catchment wall heights as planned appear to be OK. There will be a need to do some trimming of the slope immediately above the catchment.wall to establish grade and the surface Swale. Jim will shoot the area prior to forming the wall. Working safety is important. Final temporary slopes will need to be trimmed to provide a safe work area for the wall crew. OK to place concrete in the keyway., Jim is planning on pulling the temporary wood shoring as the concrete is being placed. If heavy caving occurs prior to placement of concrete, caved soils are to be removed from the keyway area and keyway backfill area. Concrete is scheduled for today.

Provide upper terminations for the drainage board that is exposed on the uphill side of the catchment wall and along the north foundation wall of the house. This can be done by cutting the drainage board close to or slightly below grade and placing a piece of flashing over the top of the drainage board. The flashing can be nailed to the concrete and glued with construction glue to. the outside of the drainage board. This is to keep rocks and dirt from getting behind the drainage material. 2. Verify that there is 3 vertical feet of clear wall on the uphill side of the catchment wall. The drainage from the seepage above the wall should be directed into the yard drains through surface swales. It is ok for the drainage to infiltrate for the time being but for the long term it needs to go to the yard drains. 3. 1 would like to verify that the downspouts are connected to the tight line. This can be done by lowering a sewer camera down the downspouts to verify that the pipe is not perforated. It would be a good idea to camera all of the pipes now as well. 4.. I need to talk with Brian about final landscaping. One of our tasks is the final erosion control review, that usually occurs after the landscaping is put in. 5.

Terra representative was on -site to observe TV of roof drain lines and erosion control measures. While on -site we observed the following: • We observed the inside of each roof drain downspout with a TV/camera: All of the downspouts were tied into tight- line pipe directed to the storm, drain system. The tight line pipe was partially crushed on near the entrance on the west side of the house. The plumber located the crushed section and indicated it was approximately.two feet below current grade Jim Arnold indicated the pipe would be fixed in the next day or two. • We walked the site with Mr. Issacson to observe final erosion control measures still needing to be addressed. Permanent ground cover needs to be put in place on the north,.south, and west sides of the residence. These areas were staked for,ornamental landscaping at -the time of our visit. Mr. Issacson indicated that the landscaping was scheduled to take place tomorrow and topsoil and/or mulch was to be placed over any remaining exposed.native soils. We recommended sloping topsoil away from the residence and any, hardscaped areas (eg. sidewalks). We recommended rerouting water flowing from the tight line pvc pipe on the slope east of the house. The pipe can either be tight lined to the existing storm structure off the NE corner of the house upon approval of the city, or shortened to flow into the existing swale routing water to the south end 'of the site. • Growth on the slope covering the majority of the east side of the property is well, established. The two lower tub basins were partially to'mostly full of sediment. The sediment was removed from the basins during our visit. The basins should be maintained on a weekly basis. The upper tub basins were free of sediment. By: Nicolas Hoffman Copies to: Email List 12525 Willows Road ♦ Suite 1.01 ♦ Kirkland, Washington 98034, ♦ Telephone No. (425) 821-7777 Daily Field Memo .

Front side of house (west) The weeping cedar was substituted with a Japanese Maple. Both of these tree types are ornamental. The location was moved from the front house entry and conflicting under ground utilities to an open location further north in front of the house. The Mimosa Silk tree was substituted with a similar size and ornamental flowering Chinese Fringe tree. Because the finish on the planter wall at the front porch staircase was unknown at time of landscape plan approval, and after approval a rockery finish was chosen and a plant screening was no longer desired to obscure the wall, the honeysuckle vines, of two varieties were planted nearby and not directly in front of the staircase's ornamental rockery planter as shown on the plan. The grading in front of the wall also allows for an informal path and access to the front yard and side path. The 3 Califomia Lilac shrub grouping at the south end driveway entry were substituted with 1-Dwarf Hinoki Cypress;1 Red Edge Hebe and 1 Dwarf Red Rhododendron in front of it in order to provide a corner accent. Approximately 4 Shore Junipers of similar low growing and drought tolerant characteristics substitute for approximately 4 Spreading Yews which were difficult to find all in stock or sold at plant nurseries. The Rock Soapwart groundcover at the drain near the stairs was relocated to spaces under and near the Chinese Fringe tree. An additional (1 Cotoneaster, 1 Sensation Lilac, 1 Barberry, 4 Nandina and approximately 4 Shore Junipers) 11.shrubs beyond the plan quantity were planted on the west side of the house. Back side of house (east) Several nurseries sold out of the Kerria Rose, so 5 Lilac Azaleas were substituted. Azaleas are included in the same genus as the adjacent rhododendrons behind the house. Different varieties of rhododendrons as well as the variety specified on the plant list were planted to meet the total number of Mrs. Furnival and Hallelujah Hall rhododendrons on the plan due to plant availability. The same mature plant size and growth.pattem were targeted. Because a planter box was removed and replaced with concrete patio area, after landscape plan approval, 10 shrubs and 2 strawberry trees could not be planted. An additional (2 Oregon grape, 3 Dwarf Viburnum) 5 shrubs and 2 vine maple trees were planted behind the house. North and south side of house An additional 1 Ninebark shrub and 1 Hinoki Cypress was planted on the north side of the house. 5 of the fems specified on the plan were transferred to the south to provide a grouping of pacific northwest planting on the re -graded/ disturbed area adjacent to the common area.existing vegetation.
