M.S.C.E., M.B.A. Geotechnical/ Civil Engineer November 4, 1997 Mr. Dennis V. O'Leary Chief Financial Officer Lynnwood Mortgage Corporation 6505 - 218th Street S.W., Suite 9 Mountlake Terrace, Washington 98043 Subject: Geotechnical Evaluation - Lots 2 and 3 Approximately 84th Place and 182nd Place, Edmonds, WA This engineering report presents the results of a geotechnical evaluation of the property at approximately 84th Place and 182nd Place, Edmonds, Washington. This evaluation was necessitated by owner and developer concems, as well as City of Edmonds requirements. REFERENCES: • Vicinity Map (figure 1) • Topographic Survey Map by Chadwick and Winters, of Lots 2 and 3 dated October, 1997 • Site photographs (available) BACKGROUND: It is understood that Lots 2 and 3 are part of an overall parcel containing Lot No. 1 with existing residence, and Lots 2, 3 and 4 (see Survey map and plot plans). This investigation deals with Lots 2 and 3 with regard to geotechnical slope issues. It is understood that property owner wishes to construct a single family residence on Lot 3 and another single family residence on Lot 2. No development or construction has occurred on either Lot 2 or 3 to date. Lots 2 and 3 contain a "flatter" portion, as well as a more steeply sloped rear (southerly portion). The flatter portions of the lots currently consist of lawn grasses, with a few mature trees. The steeper (southerly) portion of the lots are densely vegetated with shrubs, bushes and trees (see photographs). SOILS - FOUNDATIONS - SITE DEVELOPMENT - INSPECTION DRAINAGE - DESIGN &PERMIT - LEGAL 17814 8th Ave. N.W. - Shoreline, Washington 98177 (206) 546-9217 - FAX 546-8442 vtachment 6 Mr. Dennis V. O'Leary Pagetwo ASSESSMENT: While not within the scope of this evaluation, this engineer assessed the existing residence on Lot 1 for any geotechnical distress. No evidence of any foundation settlements or shifting were observed. Visual assessments of Lots 2 and 3 by this engineer throughout the past year revealed no evidence of any geotechnical distress: No sliding, no creep, no shifting, nor any significant erosional degradation was observed on the overall property, including Lots 2 and 3. In order to augment existing site geotechnical information, soil test pits were dug (by backhoe) under this engineer's observation on August 9, 1997. See soil test pit logs (attached). The findings of the four soil test pits (plotted on the Survey Topographic Map) were very similar. Namely: dense brown, silty sand to approximately three (3) to four (4) foot depths. Dense to very dense grayish brown weathered glacial till (hardpan). No ground water was present in any of the four soil test pits. All test pit walls remained vertical and stable throughout the excavated time frame (approximately two hours). CO NC LUSIO NS/R ECO M MEN DATIO NS: Based on the findings of this investigation, and experience with similar sites in the area, Lots 2 and 3 are geotechnically approved for the proposed single family residences, subject to the following conditions*: Standard reinforced continuous and spread footings. Allowable bearing pressure: 2,000 p.s.f. Equivalent fluid pressure of 35 p.c.f. is recommended for any retaining wall provided the drainage zone is inspected and verified by this engineer. For retaining wall design, use a friction factor of 0.55 and passive pressure of 350 p.c.f. The foundations for the proposed StFUctures may be placed anywhere on Lots 2 and 3, outside of the dashed top -of -bank survey area (see Topographic map). In other words there are no geotechnical limitations to the proximity of the proposed resi�ences and the top -of -slope line. (it is geotechnically Mr. Dennis V. O'Leary Page three possible, but not likely, to property construct a foundation on the steeper portions of Lots 2 and 3. This would require uneconomic stabilizing techniques and methods). To be clear, the geotechnical set -back distance to the top -of -bank dashed line is zero. It is understood that political or zoning set -back distances do apply per City of Edmonds requirements. It is important to restate, however, that no set- back distance is essential for geotechnical reasons. If desired, exceptions or variances could be pursued. Geotechnical inspection by this engineer prior to any foundation concrete placement. . The proposed structures can be supported on conventional continuous and spread footings bearing on undisturbed native soils or on structural fill placed above native soils. See the later sub -section entitled General Earthwork and Structural Fill for structural fill placement and -compaction recommendations. Continuous and individual spread footings should have minimum widths of eighteen (18) and twenty- four (24) inches, respectively, and should be bottomed at least eighteen (18) inches below the lower adjacent finish ground surface. Depending on the final site grades, some overexcavation may be required below footings to expose competent native soils. Unless lean concrete is used to fill the over excavated hole, the width of the overexcavation at the bottom must be at least as wide as the sum of two times the depth of the overexcavation and the footing width. For example, an overexcavation extending two feet below the bottom of a three-foot wide footing must be at least seven feet wide at the base of the excavation. Footings constructed according to the above recommendations may be designed for an allowable soil bearing pressure of three thousand (3,000) pounds per square foot (p.s.f.), A one-third increase in this design bearing pressure may be used when considering short-term wind or seismic loads. For the above design criteria, it is anticipated that total post -construction settlement of footings founded on competent, native soils (or on structural fill up to five (5) feet in thickness) will be about one-half inch, with differential settlements on the order of one -quarter inch. Lateral loads due to wind or seismic forces may be resisted by friction between the foundations and the bearing soils, or by passive earth pressure acting on the vertical, embedded portions of the foundations. For the latter condition, the foundations must either be poured directly against undisturbed soil or the backfill placed around the outside of the foundation must be level structural fill. We Mr. Dennis V. O'Leary Page four recommend the following design values be used for the foundation's resistance to lateral loading: Parameter Coefficient of Friction Passive Earth Pressure Where: Design Value 0.55 350 p.c.f. (1) p.c.f. is pounds per cubic foot. (2) Passive earth pressure is computed using the equivalent fluid density. We recommend that a safety factor of at least 1.5 be used for design of the foundation's resistance to lateral loading. SLABS -ON -GRADE: Slab -on -grade floors may be supported on undisturbed, competent native soils or on structural fill. The slabs may be supported on the existing soils provided these soils can be recompacted prior to placement of the free -draining sand or gravel underneath the slab. This sand and gravel layer should be a minimum of four (4) inches thick. We also recommend using a vapor barrier such as 6-mil. plastic membrane beneath the slab with minimum overlaps of 12 inches for sealing purposes. PERMANENT FOUNDATION AND RETAINING WALLS: Retaining walls backfilled on one side only sh . ould be designed to resist lateral earth pressures imposed by the soils retained by these structures. The following recommended design parameters are for walls less than twelve (12) feet in height which restrain level backfill: Parameter Active Earth Pressure* Passive Earth Pressure Coefficient of Friction Soil Unit Weight Design Value 30 p.c.f. 350 p.c.f. 0.55 125 p.c.f. Mr. Dennis V. O'Leary Page five Where: (1) p.c.f. is pounds per cubic foot (2) Active and passive earth pressures are computed using equivalent fluid densities. For restrained walls which cannot deflect at least 0.002 times the wall height, a uniform lateral pressure of one hundred (100 p.s.f. should be added to the active equivalent fluid pressure). The values given above are to be used for design of permanent foundation and retaining walls only. An appropriate safety factor should be applied when designing the walls. We recommend using a safety factor of at least 1.5 for overturning and sliding. The above design values do not hclude the effects of any hydrostatic pressures behind the walls and assume that no surcharge slopes or loads will be placed above the walls. If these conditions exist, then those pressures should be added to the above lateral pressures. Also, if sloping backfill is desired behind the walls, then we will need to be given the wall dimensions and slope of the backfill in order to provide the appropriate design earth pressures. Heavy construction equipment should not be operated behind retaining and foundation walls within a distance equal to the height of the wall, unless the walls are designed for the additional lateral pressures resulting from the equipment. Placement and compaction of retaining wall backfill should be accomplished with hand -operated equipment. Retaining Wall Backfill Backfill placed within eighteen (18) inches of any retaining or foundation walls should be free -draining structural fill containing no organics. This backfill should contain no more than five (5) percent silt or clay particles and have no particles greater than four (4) inches in diameter. The percentage of particles passing the No. 4 sieve should be between twenty-five (25) and seventy (70) percent. Due to their high silt content, if the native soils are used as backfill, a drainage composite, such as Mirafi and Enkadrain, should be placed against the retaining walls. The drainage composites should be hydraulically connected to the foundation drain system. the purpose of these backfill requirements is to assure that the design criteria for the retaining wall as not exceeded because of a build-up of hydrostatic pressure behind the wall. The subsection entitled General Earthwork and Structural Fill contains Mr. Dennis V. O'Leary Page six recommendations regarding placement and ecompaction of structural fill behind retaining and foundation walls. EXCAVATION AND SLOPES: In no case should excavation, slopes bee greater than the limits specified in local, state and national government safety regulatijons. Temporary cuts up to a height of four (4) feet deep in unsaturated soils may bEa vertical. For temporary cuts having a height greater than four (4) feet, the cut shou ild have an inclination no steeper than 1:1 (Horizontal: Vertical) from the top of the slope to the bottom of the excavation. Under specific recommendations by the geo-technical engineer, excavation cuts may be modified for site conditions. All pern-ianent cuts into native soils should be inclined no steeper than 2:1 (H:V). Fill slopes should not exceed 1:1 (H:V). It is imporlant to note that sands do cave suddenl'y, and without warning. The contractors should be made aware of this potential hazarrd. Water should not be allowed to flow uncontrolled over the top of any temporary or permanent slope. All permanently exposeed slopes should be seeded with an appropriate species of vegetation to reduce Eerosion and improve stability of the surficial layer of soil. DRAINAGE CONSIDERATIONS: Footing drains are recommended at th e base of all footings and retaining walls. These drains should be surrounded by at lea:st six (6) inches of one -inch -minus washed rock wrapped in non -woven geotextil le filter fabric (Mirafi 140N, Supac 4NP, or similar material). At the highest point, the per-forated pipe invert should be at least as low as the bottom of the footing and it should be sloped for drainage. All roof and surface water drains must be kept separate fr-orn the foundation drain system. No groundwater was observed in any of the test pits during the field work. Seepage into the planned excavation is poss ible, and likely if excavation occurs during winter months, and if encountered sho, -uld be drained away from the'site by use of drainage ditches, perforated pipe, French cdrains, or by pumping from sumps interconnected by shallow connector trenches at the bottom of the excavation. The excavation and site should be gracJed so that surface water is directed off the site and away from the tops of slopes. Weater should not be allowed to stand in any area where foundations, slabs, or pavements are to be constructed. Any exposed slopes to be covered with plastic to minimize -erosion. Final site grading in areas adjacent to buildings should be sloped at leaat two (2) percent away from the building, except where the area adjacent to the buildingg is paved. Mr. Dennis V. O'Leary Page seven GENERAL EARTHWORK AND STRUCTURAL FILL: The proposed building and pavement areas should be stripped and cleared of all surface vegetation, all organic matter, and other deleterious material. The stripped or removed materials should not be mixed with any materials to be used as structural fill. NOTE: Specific clearing limits to'be established at pre -construction meeting with City of Edmonds building officials and inspectors. Structural fill is defined as any fill placed under the building, behind permanent retaining or foundation walls, or in other areas where the underlying soils needs to support loads. This engineer should observe site conditions during and after excavation prior to placement of any structural fill. All structural fill should be placed. in horizontal lifts with a moisture content at or near the optimum moisture content. The optimum moisture content is that moisture content which results in the greatest compacted dry density. The moisture content of fill soils is very important and must be closely controlled during the filling and compaction process. The allowable thickness of the fill lift will depend on the material type, compaction equipment, and the number of passes made to compact the lift. In no case should the lift's exceed twelve (12) inches in loose thickness. The following table presents recommended relative compaction for structural fill: Location of Fill Placement Beneath footings, slabs or walkways Behind retaining walls Beneath pavements Minimum Relative Compaction 95% 90% 95% for upper 12 inches of . subgrade, 90% below that level Where: Minimum relative compaction is the ratio, expressed in percentages, of the compacted dry density to the maximum dry density, as determined in accordance with ASTM Test Designation D-1557-78 (Modified Proctor). Mr. Dennis V. O'Leary Page eight Use of On -Site Soils If grading activities take place during wet weather, or when the silty, on -site soils are wet, site preparation costs may be higher because of delays due to rains and the potential need to import granular fill. The on -site soils are generally silty and thus are moisture sensitive. Grading operations will be difficult when the moisture content of these soils exceeds the optimum moisture content. Moisture sensitive soils will also be susceptible to excessive softening and "pumping" from construction equipment traffic when the moisture content is greater than the optimum moisture content. Ideally, structural fill which is to be placed in wet weather should consist of a granular soil having no more than five (5) percent silt or clay particles. The percentage of particles passing the No. 200 sieve should be measured from that portion of the soil passing the three -quarter -inch sieve. The use of "some" on -site soils for fill material may be acceatable if the upper organic materials is segregated and moisture contents are monitored by engineering inspection. DRAINAGE CONTROLS: No drainage problems were evident on Lots 2 and 3. Surface runoff flows generally westerly (from the flatter portions of the lots). This engineer recommends compliance with the City of Edmonds standard storm water drainage controls. The surficial sandy soils are such that it is practical to utilize an Infiltration storm water system. CONCRETE: All foundation concrete (footings, stem walls, slabs, any retaining walls, etc.) shall have a minimum cement content of 5-1/2 sacks per cubic yard of concrete mix. INSPECTION: The recommendations of this report are only valid when key geotechnical aspects are inspected by this engineer during construction: • Soil cut s • Foundation subgrade verification Mr. Dennis V. O'Leary Page nine • Any retaining wall, or rockery placement • Any fill placement and compaction • Subsurface drainage installation SUMMARY: The two proposed single family residences (on Lots 2 and 3) are geotechnically viable when constructed in accordance with the recommendations herein, compliance with City of Edmonds approved plans and key geotechnical inspection during construction. There are no geotechnical constraints limiting the proximity of the proposed residences to any sloped portion of the property. As a practical measure, this engineer recommends the residences be situated no further southerly than the dashed top -of -slope line. If desired, however, it is geotechnically feasible to construct the residences beyond (more southerly) than the dashed survey line. GEOTECHNICAL REVIEW OF PLANS: Prior to the City of Edmonds issuing a building permit, this engineer should review the specific house plans for compliance with the recommendations of this geotechnical report. CLOSURE: The findings and recommendations of this report were prepared in accordance with generally accepted professional engineering principles and practice. No other warranty, either express or implied, is made. The conclusions are based on the results of the field exploration and interpolation of subsurface conditions between explored locations. If conditions are encountered during construction that appear to be different than those described in this report, this engineer should be notified to observe the situation and review and verify or modify the recommendations.

The c hearing on the application was opened at 10:44 a.m., January 15, 1998, in the City Hall, z' Edmonds, Washington, and closed for oral testimony at 11:46 a.m. The hearing was held open until 5:00 p.m., January 15, 1998 to allow staff to submit information requested by the e*xaminer. 0 Incorpormed August 11, 1890 9 Sister Cities International — Hekinan, Japan Hearing Examiner Decision Case No. V 97-145 Page 2 Participants at the public hearing and the exhibits offered and entered are listed in this report. A verbatim recording of the hearing is available in the Planning Division. HEARING TESTIMONY: The following is a summary of the testimony offered at the public hearing. From the City: Karissa Kawamoto, Project Planner, reviewed the staff advisory report (Exhibit A) and recommended a modified approval the request. From the Applicant: Rob Michel, applicant, submitted Exhibits B, C, D & F into the record. He read from Exhibit F which outlined his arguments and proposed changes to conditions recommended by City staff in Exhibit A. Dennis Bruce, PE, applicant's engineer, discussed the geotechnical report (Attachment 7 to Exhibit A) and testified that from an engineering standpoint there would be no hazard to the slope or to other properties if the proposal is built in accordance with the recommendations found in the geotechnical report. Jay Young, real estate broker, submitted Exhibits F & G into the record and. testified that in his opinion the 15 foot setback from the top of the slope, as recommended by staff, would place an unnecessary financial hardship on the owner of the lot because of view impacts. From the Community: No one from the general community spoke at the hearing. C, CORRESPONDENCE: One letter objecting to the request was received (Attachment 8 to Exhibit A). FINDINGS OF FACT AND CONCLUSIONS A. SITE DESCRIPTION 1. Site Development And Zoning: a. Facts: 1) Size: The subject property is approximately 17,952 square feet (see Exhibit A, Attachment 7). 2) Land Use: The subject property is undeveloped and vacant. 3) Zoning: The subject property is located in a Single -Family Residential (RS- 12) zone (see Exhibit A, Attachment 1). 4) Terrain and Vegetation: The steep slope critical area is located in the southern portion of the property. It contains dense vegetation, shrubs, C> Hearing Examiner Decision Case No. V 97-145 Page 3 blackberry and trees. The northern portion has a moderate rise with fewer trees and the ground is covered by grass. 2. Neighboring Development And Zoning: a. Fact: The properties to the north, south, east and west are zoned Single -Family Residential (RS-12) and either vacant or are developed with single-family homes (see Exhibit A, Attachment 1). B. STATE ENVIRONMENTAL POLICY ACT (SEPA) 1. Fact: Variances granted based on special circumstances are exempt from SEPA review (WAC 197-11-800(6)(b) and ECDC 20.15A.080). C. EDMONDS COMMUNITY DEVELOPMENT CODE (ECDC) COMPLIANCE 1. Critical Areas Compliance a. Facts: 1) This proposal is subject to review under ECDC Chapter 20.153 (Critical Areas Ordinance). 2) The applicant has submitted a Critical Areas Checklist (CA-97-236) and it was determined that a study was required. b. Conclusion: The survey and top of slope determination dated October 1997 was done by Robert Winters P.L.S. of Chadwick and Winters. A geotechnical report dated November 4, 1997 was performed by Dennis Bruce, P.E. It supports the request to construct within the critical area building setback and buffer. 2. Compliance with RS-12 Zoning Standards a. Fact: The short plat (S-28-79) declared this property a flag lot. Current policy in regards to flag lot setbacks is to consider all setbacks as "side" setbacks. b. Conclusion: The structure as proposed will comply with the requirements of the RS-12 zoning standards. D. COMPLIANCE WITH REQUIREMENTS FOR A VARIANCE Fact: ECDC Section 20.15B.180. establishes the criteria (special circumstance and the minimum variance necessary) with which a Critical Area Variance may be granted by the Hearing Examiner. The applicant has submitted declarations with their submittal which address the variance decisional criteria as follows (see Exhibit A, Attachment 3): a) Special Circumstances (applicant statement): Because of the special circumstances applicable to the subject property, including size, shape, topography, location of surrounding steep slopes, strict application of this title would deprive the subject property all reasonable use of the property. See attached plot plan showing,, a building area of only 486 square feet. Hearing Examiner Decision Case No. V 97-145 Page 4 b) Minimum variance, not materially detrimental (applicant statement): The granting of this variance is the minimum necessary to accommodate the development proposal which is a building area enjoyed by other lot owners in the area. This proposal will not be materially detrimental to the public welfare or injurious to the property or improvements in the vicinity and zone in which the property is situated because development will follow the engineer's guidelines and described in the attached Geological report. The proposed development is not contrary to the goals and purposes of the chapter. E. COMPLIANCE WITH REQUIREMENTS FOR REASONABLE USE EXCEPTION 1. Fact: ECDC Section 20.15B.040(C) establishes the decisional criteria for a Reasonable Use Exception approval by the Hearing Examiner. Criteria number 7 states that a reasonable use exception may only be applied for if a variance pursuant to ECDC Section 20.15B. 170(A). a) Denial of Reasonable Use (applicant statement): This chapter would deny all reasonable use of the subject property because Chapter 20.15B. I 10 of the Edmonds Community Development Code requires a fifty (50) foot wide buffer from geological hazardous areas and section 20.15B.080 (C) requires a fifteen (15) foot building set back from any required buffer. Please see attached drawing which leaves only 486 square feet of building area. b) No other reasonable use consistent with zoning (applicant statement): There is no other reasonable use consistent with the underlying zoning with less impact on the 1. 0 critical area or its buffer, either primary or permitted secondary uses. c) No unreasonable threat to public (applicant statement): The proposed development will not pose any threat to the public health, safely or welfare on or off the property because the proposed single family residence will be built in accordance with the Geotechnical Engineer's guidelines. All development will be performed within the property lines with strict controls to prevent any debris or material encroaching onto adjacent properties. d) Minimum reduction of critical area to allow for reasonable use (applicant statement): The proposed alteration to the critical area and its buffer will be minimized as much as possible to allow a reasonable building area as enjoyed by existing lot owners in the area. No building is planned in the 40% slope area and the proposed building will be set back approximately 25 feet from the west property line. e) Compliance with all other State and Federal laws (applicant statement) The proposed activity complies with all state local and federal laws. No sediment or pollution challenges. No floodplains involved. Wastewater to be removed from site through city sewer system. k Hearing Examiner Decision Case No. V 97-145 P -e 5 a., f) Requested Reasonable Use Exception is not due to any current or previous owners action (applicant statement): Since the lot was platted and recorded in 198 1, the economic use deficiency was created after the effective date of the adoption of this new ordinance. ONCLUSIONS FOR THE VARIANCE CRITERIA: F. C The site has both an upward and downward slope. The critical slope virtua ly splits the subject property in half. After the critical area buffer, the additional building setback from the buffer, and the standard setback from the other property lines, a small, odd shaped building envelope remains. 2. The building footprint proposed by the applicant is 2, 100 square for the house and ge. As proposed, the garage would be up to the top a 900 square foot attached garat'.. t) of slope identified by the geotechnical study and a side property line setback to the east and the majority of the home appears to be at least 15 feet away from the top of slope. The geotechnical report does indicate a very stable slope and C> construction can occur anywhere on the property with proper techniques and materials. G. CONCLUSIONS FOR THE REASONABLE USE CRITERIA: 1. The size and location of the critical area is such that the use of the property is limited to a very small, odd shaped home. An exception is necessary to allow a reasonable use of the property. 2. The RS-12 zoning designation limits development of the property to residential homes and accessory uses, similar to what is proposed. The geotechnical evaluation performed by Dennis Bruce P.E. dated November 4, 1997 approved construction on the site subject to several conditions and recommendations. 4. The applicant has requested elimination of both the 50 foot critical area buffer and 15 foot building setback from a critical area buffer. If approved as conditioned below, the proposal would have a minimal temporary impact on the critical area and will allow for a reasonable use of the property. 5. The proposal will comply with all Federal, State and local laws and ordinances with the exception of these variance requests. 6. The short plat which created this lot was processed in the late 70's, early 80's, tk. prior to adoption of the Critical Areas chapter of the ECDC. None of the lots from the short plat have had development requests to date. It does not appear as if the reasonable use exception or variance request is the result of the actions of the current or previous owners.

This evaluation was necessitated by owner and developer concerns, as well as City of Edmonds requirements. REFERENCES: • Vicinity Map (figure 1) Topographic Survey Map by Chadwick and Winters, of Lots 2 and 3 dated October, 1997 • Site photographs (available) BACKGROUND: It is understood that Lots 2 and 3 are part of an overall parcel containing Lot No. 1 with existing residence, and Lots 2, 3 and 4 (see Survey map and plot plans). This investigation deals with Lots 2 and 3 with regard to geotechnical slope issues. It is understood that property owner wishes to construct a single family residence on Lot 3 and another single family residence on Lot 2. No development or construction has occurred on either Lot 2 or 3 to date. Lots 2 and 3 contain a "flatter" portion, as well as a more stee . ply sloped rear (southerly portion). The flatter portions of the lots currently consist of lawn grasses, with a few mature trees. The steeper (southerly) portion of the lots are densely vegetated with shrubs, bushes and trees (see photographs). SOILS - FOUNDATIONS - SITE DEVELOPMENT -. INSPECTION DRAINAGE - DESIGN & PERMIT - LEGAL 17814 8th Ave. N.W. - Shoreline, Washington 98177 (206) 546-9217 - FAX 546-8442 %ttachment 6 ' Mr. Dennis V. O'Leary Page two ASSESSMENT: While not within the scope of this evaluation, this engineer assessed the existing residence on Lot 1 for any geotechnical distress. No evidence of any foundation settlements or shifting were observed. Visual assessments of Lots 2 and 3 by this engineer throughout the past year revealed no evidence of any geotechnical distress: No sliding, no creep, no shifting, nor any significant erosional degradation was observed on the overall property, including Lots 2 and 3. In order to augment existing site geotechnical information, soil test pits were dug (by backhoe) under this engineer's observation on August 9, 1997. See soil test pit logs (attached). The findings of the four soil test pits (plotted on the Survey Topographic Map) were very similar. Namely: dense brown, silty sand to approximately three (3) to four (4) foot depths. Dense to very dense grayish brown weathered glacial till (hardpan). No ground water was present in any of the four soil test pits. All test pit walls remained vertical and stable throughout the excavated time frame (approximately two hours). CO NC LUS10 NS/R ECO MM EN DATIO NS: Based on the findings of this investigation, and experience with similar sites in the area, Lots 2 and 3 are geotechnically approved for the proposed single family residences, subject to the following conditions: Standard reinforced continuous and spread footings. Allowable bearing pressure: 2,000 p-s-f- Equivalent fluid pressure of 35 p.c.f. is recommended for any retaining wall provided the drainage zone is inspected and verified by this engineer. For retaining wall design, use a friction factor of 0.55 and passive pressure of 350 p.c.f. The foundations for the proposed structures may be placed anywhere on Lots 2 and 3, outside of the dashed top -of -bank survey area (see Topographic map). In other words, there are no geotechnical limitations to the proximity of the proposed residences and the top -of -slope line. (It is geotechnically Mr. Dennis V. O'Leary Page three possible, but not likely, to properly construct a foundation on the steeper portions of Lots 2 and 3. This would require uneconomic stabilizing techniques and methods). To be clear, the geotechnical set -back distance to the top -of -bank dashed line is zero. It is understood that political or zoning set -back distances do apply per City of Edmonds requirements. It is important to restate, however, that no set- back distance is essential for geotechnical reasons. If desired, exceptions or variances could be pursued. Geotechnical inspection by this engineer prior to any foundation concrete placement. The proposed structures can be supported on conventional continuous and spread footings bearing on undisturbed native soils or on structural fill placed above native soils. See the later sub -section entitled General Earthwork and Structural Fill for structural fill placement and compaction recommendations. Continuous and individual spread footings should have minimum widths of eighteen (18) and twenty- four (24) inches, respectively, and should be bottomed at least eighteen (18) inches below the lower adjacent finish ground surface. Depending on the final site grades, some overexcavation may be required below footings to expose competent native soils. Unless lean concrete is used to fill the over excavated hole, the width of the overexcavation at the bottom must be at least as wide as the sum of two times the depth of the overexcavation and the footing width. For example, an overexcavation extending two feet below the bottom of a three-foot wide footing must be at least seven feet wide at the base of the excavation. Footings constructed according to the above recommendations may be designed for an allowable soil bearing pressure of three thousand (3,000) pounds per square foot (p.s.f.). A one-third increase in this design bearing pressure may be used when considering short-term wind or seismic loads. For the above design criteria, it is anticipated that total post -construction settlement of footings founded on competent, native soils (or on structural fill up to five (5) feet in thickness) will be about one-half inch, with differential settlements on the order of one -quarter inch. Lateral loads due to wind or seismic forces may be resisted by friction between the foundations and the bearing soils, or by passive earth pressure acting on the vertical, embedded portions of the foundations. For the latter condition, the foundations must either be poured directly against undisturbed soil or the backfill placed around the outside of the foundation must be level structural fill. We Mr. Dennis V. O'Leary Page four recommend the following design values be used for the foundation I s resistance to lateral loading: Parameter Coefficient of Friction. Passive Earth Pressure Where: Design Value 0.55 350 P.C.f. (1) p.c.f. is pounds per cubic foot. (2) Passive earth pressure is computed using the equivalent fluid density. We recommend that a safety factor of at least 1.5 be used for design of the foundation's resistance to lateral loading. SLABS -ON -GRADE: Slab -on -grade floors may be supported on undisturbed, competent native soils or on structural fill. The slabs may be supported on the existing soils provided these soils can be recompacted prior to placement of the free -draining sand or gravel underneath the slab. This sand and gravel layer should be a minimum of four (4) inches thick. We also recommend using a vapor barrier such as 6-mil. plastic membrane beneath the slab with minimum overlaps of 12 inches for sealing purposes. PERMANENT FOUNDATION AND RETAINING WALLS: Retaining walls backfilled on one side only sh ould be designed to resist lateral earth pressures impo . sed by the soils retained by these structures. The following recommended design parameters are for walls less than twelve (12) feet in height which restrain level backfill: Parameter Active Earth Pressure* Passive Earth Pressure Coefficient of Friction Soil Unit Weight Design Value 30 p.c.f. 350 p.c.f. 0.55 125 p.c.f. Mr. Dennis V. O'Leary Page five Where: (1) p.c.f. is pounds per cubic foot (2) Active and passive earth pressures are computed using equivalent fluid densities. For restrained walls which cannot deflect at least 0.002 times the wall height, a uniform lateral pressure of one hundred (100 p.s.f. should be added to the active equivalent fluid pressure). The values given above are to be used for des ' ign of permanent foundation and retaining walls only. An appropriate safety factor should be applied when designing the walls. We recommend using a safety factor of at least 1.5 for overturning and sliding. The above design values do not include the effects of any hydrostatic pressures behind the walls and assume that no surcharge slopes or loads will be placed above the walls. If these conditions exist, then those pressures should be added to the above lateral pressures. Also, if sloping backfill is desired behind the walls, then we will need to be given the wall dimensions and slope of the backfill in order to provide the appropriate design earth pressures. Heavy construction equipment should not be operated behind retaining and foundation walls within a distance equal to the height of the wall, unless the walls are designed for the additional lateral pressures resulting from the equipment. Placement and compaction of retaining wall backfill should be accomplished with hand -operated equipment. Retaining Wall Backfill Backfill placed within eighteen (18) inches of any retaining or foundation walls should be free -draining structural fill containing no organics. This backfill should contain no more than five (5) percent silt or clay particles and have no particles greater than four (4) inches in diameter, The percentage of particles passing the No. 4 sieve should be between twenty-five (25) and seventy (70) percent. Due to their high silt content, if the native soils are used as backfill, a drainage.composite, such as Mirafi and Enkadrain, should be placed against the retaining walls. The drainage composites should be hydraulically connected to the foundation drain system. th * e purpose of these backfill requirements is to assure that the design criteria for the retaining wall as not exceeded because of a build-up of hydrostatic pressure behind the wall. The subsection entitled General Earthwork and Structural Fill contains Mr. Dennis V. O'Leary Page six recommendations regarding placement and compaoAction of structural fill behind retaining and foundation walls. EXCAVATION AND SLOPES: In no case should excavation. slopes be grealtater than the limits specified in local, state and national government safety regulations. TTemporary cuts up to a height of four (4) feet deep in unsaturated soils may be vertics:al. For temporary cuts having a height greater than four (4) feet, the cut should havege an inclination no steeper than 1:1 (Horizontal: Vertical) from the top of the slope to the 1:1 bottom of the excavation. Under specific recommendations by the geotechni-iical engineer, excavation cuts may be modified for site conditions. All permanent, - cuts into native soils should be inclined no steeper than 2:1 (H:V). Fill slopes shoulold not exceed 1:1 (H:V). It is important to note that sands do cave suddenly, and - without warning. The contractors should be made aware of this potential hazard. Water should not be allowed to flow uncontrololled over the top of any temporary or permanent slope. All permanently exposed slopeges should be seeded with an appropriate species of vegetation to reduce erosion and improve stability of the surficial layer of soil. DRAINAGE CONSIDERATIONS: Footing drains are recommended at the base e of all footings and retaining walls. These drains should be surrounded by at least six (E36) inches of one -inch -minus washed rock wrapped in non -woven geotextile filter - fabric (Mirafi 140N, Supac 4NP, or similar material). At the highest point, the perforated IJ pipe invert should be at least as low as the bottom of the footing and it should be slop::ped for drainage. All roof and surface water drains must be kept separate from the e foundation drain system. No groundwater was observed in any of the te!est pits during the field work. Seepage into the planned excavation is possible, an nd likely if excavation occurs during winter months, and if encountered should be o drained away from the site by use of drainage ditches, perforated pipe, French drains, c:)or by pumping from sumps interconnected by shallow connector trenches at the bottom of the excavation. The excavation and site should be graded so ttthat surface water is directed off the site and away from the tops of slopes. Water shccDuld not be allowed to stand in any area where foundations, slabs, or pavements are to t1be constructed. Any exposed slopes to be covered with plastic to minimize erosion. n. Final site grading in areas adjacent to buildings should be sloped at least two (22) percent away from the building, except Where the area adjacent to the building is pav%ved. Mr. Dennis V. O'Leary Page seven GENERAL EARTHWORK AND STRUCTURAL FILL: The proposed building and pavement areas should b -e stripped and cleared of all surface vegetation, all organic matter, and other deleteri0ous material. The stripped or removed materials should not be mixed with any materialss to be used as structural fill. NOTE: Specific clearing limits to be established at pre-con;struction meeting with City of Edmonds building officials and inspectors. Structural fill is defined as any fill placed under the building, behind permanent retaining or foundation walls, or in other areas where the un-derlying soils needs to support loads. This engineer should observe site condition--.- during and after excavation prior to placement of any structural fill. All structural fill should be placed in horizontal lifts witfh a moisture content at or near the optimum moisture content. The optimum moisture content is that moisture content which results in the greatest compacted dry density. The moisture content of fill soils is very important and must be closely controlled duri ng the filling and compaction process. The allowable thickness of the fill lift will depend on th e material type, compaction equipment, and the number of passes made to c. ompact the lift. In no case should the lifts exceed twelve (12) inches in loose thickness. The following table presents recommended relative compaction for structural fill: Location of Fill Placement Beneath footings, slabs or walkways Behind retaining walls Beneath pavements Minimuim Relative Comipaction 95% 90% 95% for upper 12 inches of subgrade, 909/a below that'level Where: Minimum relative Compaction is the ratio, expressed in percentages, of the compacted dry density to the maximum dry density, as determined in accordance with ASTM Test Designation D-1557-78 (Nodified Proctor). Mr. Dennis V. O'Leary Page eight Use of On -Site Soils If grading activities take place during wet weather, or when the silty, on -site soils are wet, site preparation costs may be higher because of delays due to rains and the potential need to import granular fill. The on -site soils are generally silty and thus are moisture sensitive. Grading operations will be difficult when the moisture content of these soils exceeds the optimum moisture content. . Moisture sensitive soils will also be susceptible to excessive softening and "pumping" from construction equipment traffic when the moisture content is greater than the optimum moisture content. Ideally, structural fill which is to be placed in wet weather should consist of a granular soil having no more than five (5) percent silt or clay particles. The percentage of. particles passing the No. 200 sieve should be measured from that portion of the soil passing the three -quarter -inch sieve. The use of "some" on -site soils for fill material.may be acceptable if the upper organic materials is segregated and moisture contents are monitored by engineering inspection. DRAINAGE CONTROLS: No drainage problems were evident on Lots 2 and 3. Surface runoff flows generally westerly (from the flatter portions of the lots). This engineer recommends compliance with the City of Edmonds standard storm water drainage controls. The surficial sandy soils are such that it is practical to utilize an infiltration storm water system. CONCRETE: All foundation concrete (footings, stem walls, slabs, any retaining walls, etc.) shall have a minimum cement content of 5-1/2 sacks per cubic yard of concrete mix. INSPECTION, The recommendations of this report are only valid when key geotechnical aspects are inspected by this engineer during construction: • Soil cut's • Foundation subgracle'verification Mr. Dennis V. O'Leary Page nine • Any retaining wall, or rockery placement • Any fill placement and compaction • Subsurface drainage installation SUMMARY: The two proposed single family residences (on Lots 2 and 3) are geotechnically viable when constructed in accordance with the recommendations herein, compliance with City of Edmonds approved plans and key geotechnical inspection during construction. There are no geotechnical constraints limiting the proximity of the proposed residences to any sloped portion of the property. As a practical measure, this engineer recommends the residences be situated no further southerly than the dashed top -of -slope line. If desired, however, it is geotechnically feasible to construct the residences beyond (more southerly) than the dashed survey line. GEOTECHNICAL REVIEW OF PLANS: Prior to the City of Edmonds issuing a building permit, this engineer should review the specific house plans for compliance with the recommendations of this geotechnical report. CLOSURE: The findings and recommendations of this report were prepared in accordance with generally accepted professional engineering principles and practice. No other warranty, either express or implied, is made. The conclusions are based on the results of the field exploration and interpolation of subsurface conditions between 'explored locations. If conditions are encountered during construction that appear to be different than those described in thisreport, this engineer should be notified to observe the situation and review and verify or modify the recommendations. If there are any questions, do not hesitate to call. AV Dennis M. Bruce, P.E.
