Based on these findings, prior to submission of any development permit, you will be required satisfy the requirements of ECDC 20.1513 by completing a Critical Areas Study consisting of the following: Steep Slope Hazard Area Delineation Requirements: To determine if a Steep Slope Hazard Area does exist, a topographic survey prepared by a Licensed Land Surveyor delineating Steep Slope Hazard. Areas must be completed. Any slope of 40% or more with at least 20 feet of rise will be classified as a Steep Slope Hazard Area. A 50- foot buffer is required from both the top and toe of the slope. A 15-foot building setback is required from the 50-foot buffer. For development of any kind which is proposed within the critical area, 50-foot buffer or 15-foot buffer setback, it must be shown that the development will not adversely impact the Critical Area or its buffer, by doing one or possibly both of the following depending on the outcome of the study: For development proposals which will occur within the 50-foot buffer, but no closer than 10 feet from the top or toe of the slope, the 50-foot buffer requirement maybe reduced to 10 feet if a study is completed by a licensed geologist or geotechnical engineer which clearly demonstrates that the proposed buffer alteration will have no adverse impact upon the site, the public or any private party. 2. If development must occur within the critical area, buffer, and/or buffer setback, and is not identified as exempt per ECDC Chapter 20.15B, a Reasonable Use Exception and Variance must be obtained pursuant to ECDC 20.15B.170A and 20.15B.040C. .. 0 • Stream Based on the above findings, a Critical Areas Study is required to determine the hydrology of the area and to delineate the approximate boundaries of the stream and identify its buffers. The required qualified critical areas consultant needed to perform the study shall be a specialist in botany, fisheries, wetland biology, and/or hydrology with a minimum of two years' field experience with wetlands and/or streams in the Pacific Northwest. This critical areas study shall be performed as a three party agreement with the city selecting the consultant and the property owner or applicant paying the fees. The qualified critical areas consultant shall perform the following: 1. Classification of the stream pursuant to the criteria established in ECDC Section 20.15B.060(A)(4) and (5). 2. Delineate the edge of the stream on the site. 3. State any mitigating measures appropriate to preserving and protecting the stream. The qualified critical areas consultant shall enter into a three party contract with the applicant and the City of Edmonds as required in ECDC 20.15B.140(D), where the applicant pays for the study. The applicant may suggest qualified professionals for the City's approval. After the qualified critical areas consultant has delineated the stream boundary, a surveyor licensed by the State of Washington must perform the following: 1. Delineate the required buffer (see ECDC 20.15B.120.(A) and 20.15B.130.(C)). 2. Delineate the required building setback from the buffer (required setback is 15 feet). 3. Create a map showing the buffer and the building setback. If the results of the Critical Areas Study determine that the lot may not be developed, the applicant may apply for a Reasonable Use Exception and Variance pursuant to ECDC 20.15B. I 70(A) and 20.15B.040(C)). If the property owner wishes to apply for a specific development permit which they feel would not impact the Critical Areas located on the site, they may submit their proposal to the Planning Department for review. If the Planning Department finds that the proposed development permit will not adversely impact a Critical Areas or its buffers, a conditional waiver may be issued on a project by.project basis.

The site is located at 7707 — 171" Street SW in Edmonds as shown on the Vicinity Map in Figure 1. A single-family residence is currently located on the site. The developer. plans to construct an access road near the western property line and divide the site into seven residential lots. We understand that the existing residence will remain and will occupy one of the lots.

The site is bordered by 171' Street SW to the south and a residential lot to the west. A ravine borders the site on the eastern and northern sides. A stream was flowing at the bottom of the ravine at the time of our field reconnaissance on December 18, 2002 and February 3, 2003. The site features are shown on the Site Plan in Figure 2. A residence with some outbuildings is situated in the southern portion of the site. This area is vegetated with a grass lawn and young to mature deciduous and evergreen trees. The northern portion of the site is undeveloped, and is vegetated with blackberry bushes brush, and young to mature deciduous and P � g STY � � Y g evergreen trees. The main portion of the site slopes gently down toward the south. The ravine on the eastern side of the site slopes moderately to steeply down toward the east. The steep ravine. slope is covered with ferns, blackberry bushes, and young to mature deciduous and evergreen trees. Old growth stumps were observed on the slopes. We measured Cross -Sections A -A', B-B', and C-C' using a 100-foot tape measure and a hand-held clinometer. The cross -sections are presented as Figures 3, 4, and S. The portion of the steep slope at Cross -Section A -A', which has an approximate east -west orientation, has a total relief of approximately 30 feet. This portion of the ravine slopes toward the east with inclinations as steep as 27 degrees. The portion of the steep slope at Cross -Section B-B', which has an approximate southwest -northeast orientation, has a total relief of approximately 60 feet. This portion of the ravine slopes down towardthe northeast with inclinations as steep as 40 degrees. The portion of the steep slope at Cross -Section C-C', which has an approximate east -west orientation, has a total relief of approximately 25 feet, and slopes down toward the east with inclinations as steep as 38 degrees. NELSON GEOTECHNICAL ASSOCIATES, INC. 11 1 Geotechnical Engineering Evaluation Talbot Park Estates x Edmonds, Washington February 14, 2003 NGA File No. 360902 Page 3 Subsurface Conditions Geology Most of the Puget Sound region was affected by past intrusion of continental glaciation. The last period of glaciation, the Vashon Stade, ended approximately 10,000 to 11,000 years ago. Many of the geomorphic features seen today are a result of scouring and overriding by glacial ice. During the Vashon Stade, the Puget Sound region was overridden by over 3,000 feet of ice. Soil layers overridden by the ice sheet were compacted to a much greater extent than those that were not. The geologic units for this area are shown on the Geologic Map of the Edmonds East and Part of the Edmonds West Quadrangles, Washington, by James P. Minard (US Geological Survey, 1983). The site is mapped as till, which is described as an unsorted mixture of silt, sand, and gravel. Drift is a similar unit to till but has some sorting. Advance outwash and transitional bed materials are mapped a short distance from the site. Advance outwash is described as sand with varying amounts of gravel. Transitional bed material consists of bedded clay, silt, and fine sand. Our explorations encountered material consistent with the descriptions of drift and advance outwash, and we observed transitional bed material in the northeast section of the site, near the bottom of the ravine: Explorations - The subsurface conditions within the site were explored on December 18, 2002 by excavating two hand auger explorations, and on February 3, 2003 by excavating nine test pits with a backhoe. The hand auger explorations extended to depths of 2.8 to 3.4 feet below the ground surface, and the test pits were excavated to depths of 4.0 to 7.0 feet below the ground surface. The approximate locations of the explorations are shown on the Site Plan in Figure 2. A representative of Nelson Geotechnical Associates, Inc., (NGA) was present during the explorations, examined the soils and geologic conditions encountered, obtained samples of the different soil types, and maintained logs of the hand augers and test pits. The soils were visually classified in general accordance with the Unified Soil Classification System, presented in Figure 7. The soil logs are attached to this report and are presented as Figures 8 through 11. We present a brief summary of the subsurface conditions in the following paragraphs. For a detailed description of the subsurface conditions, the logs should be reviewed. Our two hand auger explorations were located on the slope of the ravine feature. These explorations NELSON GEOTECHNICAL ASSOCIATES, INC. Geotechnical Engineering Evaluation Talbot Park Estates Edmonds, Washington February 14, 2003 NGA File No. 360902 Page 4 encountered 0.6 to 1.5 feet of surficial topsoil material. Underlying the topsoil, we encountered silty fine to medium sand with gravel to fine to medium sand with silt and gravel. These soils extended to the bottom of the hand auger explorations, 2.8 to 3.4 feet below the ground surface. Test Pit 6, located near the north end of the planned access road, encountered 1.5 feet of loose surficial fill material composed of silty fine sand with roots and pieces of concrete. Our other eight test pit explorations encountered a surficial layer of topsoil 1.0 to 2.8 feet thick Test Pits 3 and 4, located in the northern portion of the site, encountered material generally consisting of sand with silt below the surficial topsoil and extending to the bottom of the explorations. We interpret this material as outwash. The remaining seven test pit explorations encountered silty sand with gravel beneath the topsoil and fill. This material extended to the depth explored in these test pits, and was interpreted as glacial drift. Fine to medium sand seams were observed within this material in Test Pits 5, 6, and 7. We observed silt and clay material in several shallow hand excavations in the northeastem portion of the site, on the slopes near the bottom of the ravine. We interpreted this silt and clay material as part of the Transitional bed unit. Hydrologic Conditions Ground water seepage was not observed in any of our subsurface explorations or on the steep slope, however, a perched ground water condition could possibly develop above the low -permeability soils found underlying the site. Perched water occurs when surface water infiltrates through less dense, more permeable soils and accumulates on top of the underlying, less permeable silts or flow into the joints found in the silt. The more permeable soils, in this case, consist of topsoil and fill. The less permeable soils consist of the underlying silty sand and silt. Perched water does not represent a regional ground water table within the upper soil horizons. Perched water tends to vary spatially and is dependent upon the amount of rainfall. We would expect the amount of ground water to decrease during drier times of the year and increase during wetter periods. Also, ground water seepage could outcrop on the face of the steep slope during the wetter periods of the year. NELSON GEOTECHNICAL ASSOCIATES, INC. Geotechnical Engineering Evaluation Talbot Park Estates Edmonds, Washington February 14, 2003 NGA File No. 360902 Page 5 SENSITIVE AREA EVALUATION Seismic Hazard The project is located within Zone 3 of the Seismic Zone Map shown as Figure 16-2 of the 1997 Uniform Building Code (UBC). This corresponds to a Seismic Zone Factor, Z, of 0.30. We recommend that the subsurface soils be considered Soil Profile Type SD, as described in the UBC. Hazards associated with seismic activity include liquefaction and amplification of ground motion due to soft soil. The glacially compacted soils inferred to underlie this site do not have a significant potential for liquefaction or amplification of ground motion. Erosion Hazard The criteria used for evaluation of erosion hazards include soil type, slope gradient, vegetation cover and groundwater conditions. The surface soil types (group classification) are related to the underlying geologic soil units. The Soil Survey of Snohomish County Area, Washington, by the Soil Conservation Service (SCS), was reviewed to evaluate the erosion hazard of the on -site soils. The surface soils at the site were mapped by the SCS and classified as Alderwood-Urban land complex (8 to 15 percent slopes). The erosion hazard for these soils is listed as slight. The slopes on the site have inclinations steeper than 15 percent in some areas. The erosion hazard for the steeper areas of the site is considered moderate to high. Landslide Hazard/Slope Stability The steeply sloping portion of the site has inclinations as steep as 40 degrees as measured in the field. We estimate that there is a change in elevation of up to 60 feet across the steep slopes along the eastern side of the site. The native soils that form the core of the slope are inferred to consist of competent glacially -compacted soils. We observed small scarps on the slope that appeared to be the result of shallow failures. A neighbor informed us that a failure occurred last year on a steep slope on the eastern side of the creek. We observed the scarp resulting from that failure, and some of the failed material near the bottom of the slope. This failure is interpreted to have been a shallow surface failure, and may have been the result of saturated slope conditions. NELSON GEOTECHNICAL ASSOCIATES, INC. Geotechnical Engineering Evaluation Talbot Park Estates -= Edmonds, Washington February 14, 2003 NGA File No. 360902 Page 6 We did not observe seepage on the steep slopes. We did observe several bowed mature deciduous and evergreen trees on the steep slopes. This is likely the result of soil creep. Based on the competent soils that are believed to form the core of the slope, the absence of indications of past deep-seated slope movement, and the absence of water seepage on the slope, we consider the slope to be stable with respect to deep-seated movements. However, we did observe indications that the slope has experienced shallow failures and gradual slope movement. We would expect that such events to continue in the future. There is a significant potential for shallow sloughing events to occur within the steeper portions of the site due to the steep inclination of the slopes. The potential for sloughing may be reduced by routing surface water away from the top of slope, maintaining vegetation on the slope, and repairing any areas disturbed during construction. Periodic monitoring of the site steep slopes is also recommended. With the recommended setback, these sloughing events should not adversely impact the planned structures. Slope Stability We analyzed global stability of the steep slope using a computer program titled XSTABL, version 5.2. XSTABL is a two-dimensional, limit -equilibrium, slope stability program. XSTABL generates random potential failure surfaces and determines their corresponding factors of safety with respect to failure. The factor of safety is defined as the ratio of the internal soil strength divided by the gravity driving forces that cause failure. By generating a large number of random surfaces, the factor of safety can be obtained as the lowest number calculated. The geometry of Cross -Section B-B' was used for the slope stability analysis. The factor of safety against slope failures affecting the ground surface 35 feet beyond the top of the steep slope was found to be above 1.5. The parameters and results for this analysis are shown in Figure 6. This analysis along with our field observations is the basis for establishing the recommended building setbacks. The shallow explorations within the upper _ portion of the cross-section B-B' encountered glacially consolidated sandy soil. We observed transitional bed material consisting of silt and clay in the lower section of the northern portion of the steep slope at cross-section B-B'. We did not perform laboratory shear testing of the onsite materials. We established design strengths based on visual evaluation and classification of the soils and our experience with similar conditions. NELSON GEOTECHNICAL ASSOCIATES, INC. Geotechnical Engineering Evaluation Talbot Park Estates Edmonds, Washington February 14, 2003 NGA File No. 360902 Page 7 CONCLUSIONS AND RECOMMENDATIONS General It is our opinion that the planned development is feasible from a geotechnical standpoint. It is also our opinion that the soils that underlie the site and form the core of the site slopes should be stable with respect to deep-seated earth movements, due to their inherent strength and slope geometry. These soils should provide adequate support to standard shallow foundations. There is a potential for shallow sloughing and erosion events to occur on the steeper portions of the slope. We have provided recommendations to reduce the potential of such events and a slope setback distances to reduce the risk of adverse impacts to the residences should such events occur. This is further discussed in the Steep Slope Setback subsection of this report. The residences could be supported on conventional spread footings, provided that the foundation excavations are advanced through any surficial fill, topsoil, or loose material and extended into medium dense or better native soils. Overexcavated material should be replaced with rock spalls or structural fill. The downhill footing lines, however, should be cast on native material. Surface water runoff and water from roof downspouts and yard areas should be collected and directed into appropriate drainage systems to reduce the amount of water flowing onto the steep slopes. It will be important to maintain the vegetation on the slope to reduce the erosion potential. The occurrence of sloughing on the slope can be reduced by routing storm run-off into appropriate water lines away from the slope or piping storm water to the base of the slope. Under no circumstances should water be allowed to flow over or concentrate on the site slopes, both during construction and after construction has been completed. The soils likely to be exposed during construction are considered moisture -sensitive and will disturb and erode easily when wet. We recommend that construction take place during the drier summer months, if possible. If construction takes place during the wet season, additional expenses and delays should be expected.due to the wet conditions. Additional expenses could include the need to export on -site soil, the import of clean, granular soil for fill, and the need to place a blanket of rock spalls or crushed rock in the construction traffic areas and exposed subgrades prior to placing structural fill or structural elements. We do not recommend the use of on -site soils as structural fill in wet weather. After grading, the exposed NELSON GEOTECHNICAL ASSOCIATES, INC. Geotechnical Engineering Evaluation Talbot Park Estates Edmonds, Washington February 14, 2003 NGA File No. 360902 Page 8 subgrade should be protected from construction traffic and surface runoff. Erosion Control Measures The erosion hazard for the on -site soils site is considered moderate to high, depending on how the site is graded and water is allowed to concentrate. Best Management Practices (BMPs) should be used to control erosion. Areas disturbed during construction should be protected from erosion. Measures taken may include diverting surface water away from the stripped areas and from flowing over the slope. Silt fences and/or straw bales should be erected to prevent muddy water from leaving the site or flowing over the top of the slope. Disturbed areas should be planted with vegetation at the end of construction. The vegetation should be maintained until established. The erosion potential of areas not stripped of vegetation should be low. Steep Slope Setback Uncertainties related to building along steep slopes are typically addressed by the use of building setbacks. The purpose of a setback is to establish a buffer zone between a structure and the slope margin, so that ample room is allowed for normal slope surface regression or a minor slope failure. This setback also protects the slope from the impacts of the development. From a geological standpoint, a reasonable setback is based on the slope's physical characteristics; e.g., slope height, surface angle, material composition, hydrology, etc. Other factors such as historical slope activity, rate of regression and earthwork activity along the toe of slope, are important considerations as well. Based on our slope evaluation and observations, we recommend a minimum horizontal setback distance of 25 feet between the top of the steep slope and the planned residences on Lots 2, 3, and 4. The slope in the northern portion of the site is higher and has a steeper inclination. In addition, we observed silt and clay material in the lower portion of the slope in this area. Silt and clay usually have lower strengths than sand and gravel. For these reasons, and also based on our numerical slope stability analysis, we recommend a minimum horizontal setback distance of 35 feet between the top of the steep slope and the planned residences on Lots 5, 6, and 7. The 35-foot setback for Lots 5, 6, and 7 could be reduced to 25 feet if the downhill foundation lines for these residences are suitably deepened. For these lots, we recommend that the downhill foundation lines NELSON GEOTECHNICAL ASSOCIATES, INC. Geotechnical Engineering Evaluation Talbot Park Estates Edmonds, Washington February 14, 2003 NGA File No. 360902 Page 9 be advanced a minimum of 7 feet below the existing ground surface if a 25-foot setback is desired. We should be retained to evaluate the residence foundation subgrade and setback distances prior to placing foundation forms. The existing residence on this site is located within 15 feet from the top of the steep slope. We do not know the depth of this residence's foundations, and have not evaluated the suitability of the residence setback from the steep slope. Slope and Setback Protection Protection of the setback and steep slope areas should be performed as required by the City of Edmonds. Specifically, we recommend that the setback areas not be used for placement or storage of fill materials, including temporary excavation spoils from building area preparation and excavation. Also, water should not be allowed to pond in the setback area or flow onto the face of the slope. It should be understood that the closer site soil disturbance and development are to the slope, the more risk there. is of decreasing slope stability. Care should be taken to minimize disturbance to the slope and setback surficial soils and vegetative cover both during and after construction. Of great importance to the long-term stability of the slope is the control of surface and near -surface water, and erosion protection. We recommend that all drains, including roof and yard drains, be directed away from the top of slope and routed into a permanent discharge system. Surface drainage over the slope should not be permitted. Site Preparation and Grading The first step of site preparation should be to strip any topsoil and loose soils to expose medium dense or better native soils in foundation, slab, and pavement areas. The stripped material should be removed from the site or stockpiled for later use as landscaping fill. The exposed subgrade should be compacted to a non -yielding condition. If wet conditions are encountered, alternative site stripping and grading techniques might. be necessary. These could include using a large excavator equipped with wide tracks and a smooth bucket to complete site grading and covering exposed subgrades with a layer of crushed rock for protection. If wet conditions are encountered, the subgrade should not be compacted as this NELSON GEOTECHNICAL ASSOCIATES, INC. Geotechnical Engineering Evaluation Talbot Park Estates - Edmonds, Washington February 14, 2003 NGA File No. 360902 Page 10 could cause subgrade disturbance. The prepared subgrades should be protected from construction traffic and surface water should be diverted around prepared subgrades. The on -site soils likely to be exposed during construction are considered highly moisture -sensitive and will disturb easily when wet. These soils become very difficult to compact when wet of optimum moisture content. This often results in extra excavation and the need for importing all-weather material for fill, which could significantly raise costs. We recommend that earthwork be conducted during the drier summer months, if possible. Temporary Excavations Temporary excavation stability is a function of many factors, such as the type and consistency of soils, depth of the cut, surcharge loads adjacent to the excavation, length of time a cut remains open, and the presence of surface or ground water. It is exceedingly difficult under these variable conditions to estimate - a stable, temporary, cut -slope geometry. Therefore, it should be the responsibility of the contractor to -� maintain safe slope configurations, since the contractor is continuously at the job site, able to observe the nature and condition of the cut slopes, and able to monitor the subsurface materials and ground water conditions encountered. The following information is provided solely for the benefit of the owner and other design consultants and should not be construed to imply that Nelson Geotechnical Associates, Inc., assumes responsibility for job site safety. Job site safety is the sole responsibility of the project contractor. For planning purposes, we recommend that temporary cuts in the upper loose soils be no steeper than 2 Horizontal : 1 Vertical (2H:1 V). Cuts in the underlying medium. dense to dense native materials may stand at an inclination as steep as 1 H:IV. If ground water seepage is encountered or construction traffic planned near the top of the cuts, flatter inclinations may be necessary. We recommend that cut slopes be protected from erosion. Measures taken may include covering cut slopes with plastic sheeting and diverting surface runoff away from the top of cut slopes. We do not recommend vertical slopes for cuts deeper than 4 feet if worker access is necessary. We recommend that cut slope heights and inclinations conform to WISHA/OSHA standards. NELSON GEOTECHNICAL ASSOCIATES, INC. Geotechnical Engineering Evaluation Talbot Park Estates Edmonds, Washington February 14, 2003 NGA File No. 360902 Page 11 Structural ]Fill General: We do not anticipate significant amounts of structural fill for the planned development. However, any fills placed beneath foundations, pavements, other settlement -sensitive structures, behind retaining walls, or on steep slopes should be placed as structural fill. Structural fill, by definition, is placed in accordance with prescribed methods and standards and is monitored by an experienced geotechnical professional or soils technician. Field monitoring procedures would include the performance of a representative number of in -place density tests to, document the attainment of the desired degree of relative compaction. The area to receive the fill should be prepared as outlined in the Site Preparation and Grading subsection of this report. Level benches should be excavated into slopes with greater than 20 percent inclination that will receive fill to key the new fill into the slope. These benches typically have a nominal width of approximately 4 to 8 feet, and are separated vertically by about 1 to 4 feet. Materials: Imported structural fill should consist of a good quality, free -draining, granular soil, free of organics and other deleterious material and be well -graded to a maximum size of about 3 inches. Imported all-weather fill should contain no more than about five percent fines (soil finer than U.S. No. 200 sieve, based on that fraction passing the U.S. 3/4-inch sieve). The use of the native on -site soils as structural fill would be dependent on the nature of the material encountered and moisture content control. Some drying of the soils may be necessary in order to achieve compaction. We expect that compaction of most of the native soils to structural fill specifications would be difficult, if not impossible, during wet weather. We should be retained to evaluate the suitability of using the on -site soils as structural fill at the time of construction. Fill Placement: Following subgrade preparation, placement of structural fill may proceed. All backfilling should be accomplished in uniform lifts up to 10 inches thick. Each lift should be spread evenly and be thoroughly compacted prior to placement of subsequent lifts. All structural fill should be compacted to a minimum of 95 percent of the material's maximum dry density. Maximum dry density, in this report, refers to that density as determined by the ASTM D-1557 Compaction Test procedure. The moisture content of the soils to be compacted should be within about 2 percent of optimum so that a NELSON GEOTECHN/CAL ASSOCIATES, INC. Geotechnical Engineering Evaluation Talbot Park Estates Edmonds, Washington February 14, 2003 NGA File No. 360902 Page 12 readily-compactable condition exists. It may be necessary to overexcavate and remove wet soils in cases where drying to a compactable condition is not feasible. All compaction should be accomplished by equipment of a type and size sufficient to attain the desired degree of compaction. Foundations Conventional shallow spread foundations should be placed on undisturbed medium dense or better native soils or be supported on structural fill or rock spalls extending to those soils, with the exception of the downhill footing lines which should be cast on the native material. Where less -dense soils are encountered at footing bearing elevations, the subgrade should be overexcavated to expose suitable bearing soil. The overexcavation may be filled with structural fill or concrete, or the footing may be extended to the bearing native soils. If footings are supported on structural fill, the fill zone should extend outside the edges of the footing a distance equal to one-half of the depth of overexcavation below the finished subgrade. Both perimeter and interior footings should extend at least 18 inches below the lowest adjacent finished ground surface for frost protection and bearing capacity considerations. Minimum foundation widths of 16 and 24 inches should be used for continuous and isolated spread footings, respectively, for two-story structures and 18 and 24 inches for continuous and isolated footings, respectively, for three-story structures. Standing water should not be allowed to accumulate in footing trenches. All loose or disturbed soil should be removed from the foundation excavation prior to placing concrete. For foundations constructed as outlined above, we recommend an allowable design bearing pressure of no more than 2,000 pounds per square foot (psf) be used for designing footings founded on the native medium dense soils or structural fill extending to the silt. The foundation bearing soil should be evaluated by NGA at the time of construction. We should be consulted if higher bearing pressures are needed. Current Uniform Building Code (UBC) guidelines should be used when considering increased allowable bearing pressure for short-term transitory wind or seismic loads. Potential foundation settlement using the recommended allowable bearing pressure is estimated to be less than 1 inch total and 1/2 inch differential between adjacent footings or across a distance of about 30 feet, based on our experience with similar residential projects. NELSON GEOTECHNICAL ASSOCIATES, INC. Geotechnical Engineering Evaluation Talbot Park Estates Edmonds, Washington February 14, 2003 NGA File No. 360902 Page 13 Lateral loads may be resisted by friction on the base of the footing and passive resistance against the subsurface portions of the foundation. A coefficient of friction of 0.35 may be used to calculate the base friction and should be applied to the vertical dead load only. Passive resistance may be calculated as a triangular equivalent fluid pressure distribution. An equivalent fluid density of 200 pounds per cubic foot Cucf) should be used for passive resistance design for a level ground surface adjacent to the footing. This level surface should extend horizontally a distance equal to at least three times the depth of the footing. These recommended values incorporate safety factors of 1.5 arid 2.0 applied to the estimated ultimate values for frictional and passive resistance, respectively. To achieve this value of passive resistance, the foundations should be poured "neat" against the native medium dense soils or compacted fill should be used as backfill against the footing. We recommend that the upper foot of soil be neglected when calculating the passive resistance. Slabs -on -Grade Slabs -on -grade should be supported on subgrade soils prepared as described in the Site Preparation and Grading subsection of this report. We recommend that all floor slabs be underlain by at least 6 inches of free -draining sand or gravel for use as a capillary break. We recommend that the capillary break be hydraulically connected to the footing drain system to allow free drainage from under the slab. A suitable vapor barrier, such as heavy plastic sheeting (6-mil minimum), should be placed over the capillary break material. An additional 2-inch-thick sand blanket may be used to cover the vapor barrier. This sand blanket is to protect the vapor barrier membrane and to aid in curing the concrete. Site Drainage Surface Drainage: The finished ground surface should be graded such that storm water is directed to an appropriate storm water collection system. Water should not be allowed to stand in any area where footings, slabs, or pavements are to be constructed. Final site grades should allow for drainage away from the residence and the steep slope. We suggest that the finished ground be sloped at a minimum gradient of 3 percent for a distance of at least 10 feet away from the improvements. Under no circumstances should surface water be allowed to concentrate or flow over the site slopes. j Subsurface Drainage: We recommend the use of footing drains around the residences and behind any s� subsurface walls. Footing drains should be installed at least 1 foot below planned finished floor slabs. The drains should consist of minimum 4-inch-diameter, rigid, slotted or perforated, PVC pipe surrounded NELSON GEOTECHNICAL ASSOCIATES, INC. Geotechnical Engineering Evaluation Talbot Park Estates Edmonds, Washington February 14, 2003 NGA File No. 360902 Page 14 by free -draining material wrapped in a filter fabric. We recommend that the free -draining material consist of an 18-inch-wide zone of clean (less than 3 percent fines), granular material placed along the back of the wall. Pea gravel is an acceptable drain material or drainage composite may be used instead. The free - draining material should extend up the wall to 1 foot below the finished surface. The top foot of soil should consist of impermeable soil placed over plastic sheeting or building paper to minimize surface water or fines migration into the footing drain. Footing drains should discharge into tightlines leading to an appropriate collection and discharge point with convenient cleanouts to prolong the useful life of the drains. Roof drains should not be connected to wall or footing drains.

All people who own or occupy homes on hillsides should realize that landslide movements are always a possibility, although the likelihood that such an event will actually occur may be low. The hillside should remain stable during normal environmental conditions; however, inherent to steep slope areas is the risk of movement due to extreme environmental conditions such as severe earthquakes and storms. Because of the existing sloping conditions, the area should be periodically inspected by the landowner, especially after winter storms.

Garden development in Edmonds. The props-r'ty is situated adjacent to 771h Place and just north of 17V' Street SW. It is understood that single family residences will be consu licted on these lots. The purpose of,this investigation was to establish the nature: of the. subsurface soil conditions that will provide. support to the stnietures, and to provide recommendations for the design and construction'of the foundations. Preliminary plans for these houses show that minor site grading will be required to establish building pad grades. USGS mapping for this area of Edinonds was used as a reference for this investigation. 'Site Conditions Prcvivus cleari rig and grading have been performed on this site. in c;c,nnc c:tii,n with flue overall six lot development. The access street has been paved and utilities have been installed to serve the residential lots. Observations of the ground conditions indicate that fill has been. placed over most of the lots to create the existing grades that slope generally toward the northeasL. A steep slope descends down toward the easterly side of Lbis development and there is a designated wetland west of Lot *6. Ilie slope on the easterly side of the plat is heavily covered with vine:.~ and native shrubs, and there are some mature trees located on this native 11/2 11:1V slope. Observations of this slope showed no evidence of gross failures or instability that would affect the proposed construction. According to Minard (USGS —1983) this area of Edmonds is underlain by glacial till (QvL) and advanced outwash deposits (Qva). Seven exploratory Lrenclies were dug in the area of the proposed residences to confirm the presence of fill soils and to classify 13203 Holmes Point Drive NE KA19nd, WA 98034 Fax: 425-814-5672 Phone: 425.814-3970 STREET FILE Dec,15 05 07:53p ROBERT.M PRIDE INC 425 814 5672 p.2 December 15, 2005 Mr. Jon Kvernmo page 2 the underlying nativC soils. The Lest pits encountered soft fill soils zinc] O%anics to depths of two feet and there was obvious construction debris and free remnants that were buried in the fill. Below the fill were topsoil and medium dense silty sands that were categorized as weathered till. A majority of the fill material on this plat is located on Lots 6 and 7 that are on the westerly sick: of the property. Up to seven feet of soft and loose fill with organics and debris were encountered on iAA #7. Lots 2 through 6 had fill and disturbed soils that ranged from i to as much as 4 feet as disclosed by the test pits. Groundwater s epage was not encountered in any of the exploratory test pits. Summary logs of these test pits are shown on Appendix A and their loentions are shown on Drawing No. 1. GeoLe hnical lteeommendations On the basis of our site inspection and subsurface exploration, the proposed residence foundations for Lots through 6 rrtust extend through the fi.f I and bear on the medium dense to dense native silty sands. 1,00tiug depths are expected to range from to as much as 5 feet to bear on the undisturbed native soils. An allowable soil bearing value of 200o psf may be used in the design of these footings that should have a minimum depth of 18 inches below final exterior grade. This value may he increased by 1/g to recount for temporary seismic or wind loadings. A passive earth pressure of 2O0 pef may be used to resist lateral forces. Where fill soils exceed a depth of about five feet on T.ot #7, it is recommended that the bearing wall footings by supported on driven pipe piles either 3 or q. inches in diameter. These pile-5 should be Schedule 8o galvanized pila' that are driven to refusal into the native till soils. Refusal is defined a.s less than one inch of penetration over a period of 3o and 15 seconds, respectively using a 4.50# or 850# pneumatic hammer. Each pile may be loaded up to 8 and 20 tons, respectively for working capacity. Where pipe piles are used for foundation support they should be connected with concrete grade beams that also provide support for the concrete slabs. If the upper fill soils are compacted with a vibratory roller to a depth of two feet, the floor slabs can be poured on the compacted fill. Some interior slab settlement can be expected where the depth of fill exceeds three feet. Some excavation +aril l be required to establish the building pad for the residence foundations. Excavated soils should not be used for structural fill under the residence, but may be placed in landscape amzs or hauled offsite. Normal erosion Control procedures should be in place for construction of this residence in the coming winter months.

These residences have been sited within the building setback limits as shown on the drawings by Home Design. Based on my site in.spc:cticros and geotechnical evaluation .as discussed in my December `„ d and 15rh reports, these structures can be constructed aL their proposed locations without any impact on the adjacent steep slope areas. Minimum slope setback distances from the face of the slope to the exterior foundation walls is at le ist 15 feet on Lol 3, 30 feet on Lot 4, 35 feet on Lot 5 and 35 feet on Lot G. in my opinion these setback distances are satisfactory for the site and subsurface conditions on these properties, and they will satisfy the requirements of ECDC #23.80 and 23.4v.

Charlotte Gardens Level 1 Downstream Analysis Report January 18, 2004 Page 2 TASK 3: FIELD INSPECTION AND DESCRIPTION OF DRAINAGE SYSTEM WITH EXISTING AND PREDICTED PROBLEMS A field inspection of the property, surrounding area and downstream conditions was performed by the engineer on January 18, 2004. The weather was overcast and dry. The total distance covered was 900 feet downstream from the site to Puget Sound. Upstream Drainage Analysis: The site is bordered by 171 ' Street SW to the south which intercepts any upstream runoff from the south side of the property. To the north and east is the ravine which intercepts any upstream runoff from the north and east. The site slopes from north to south which eliminates any runofffrom entering the site from the west side of the property. Therefore, there is no upstream, offsite runoff entering the site and the runoff is limited to the 2.10 acres itself.. (See Figure 4 "Downstream Drainage Analysis Map') On -site Drainage Considerations: The site is 2.10 acres in size and contains a single family dwelling and landscaping. The top half or west side of the site contains gentle slopes of approximately 6-percent, which run south to north- west. Along the east and north sides of the site are steep slopes containing a ravine which drains north-west. Along the west side of the property is a small wetland which straddles the west property line. All runoff from the site drains north east into the steep ravine. This ravine is located with in the City ofLynnwood City limits and based on the contour information there is little if any upstream area draining onto the site. Downstream Drainage Analysis: Segment 1: Ravine; From on -site to two 12-inch culverts (0' to 400) Drainage leaves the site along the north property line where it flows down the steep slopes into the ravine containing a natural drainage channel This ravine is located just south of and follows Bertola Drive and is located in the City of Lynnwood drainage basin. The runoff flows northwest where the drainage from the stream channel is intercepted by two 12-inch diameter CMP culverts located just west of the City of Lynnwood treatment plant. The storm drainage on along this segment consisted of a natural drainage channel located in the ravine. The slope of the channel was approximately 2 to 4-percent. There were no indications of overtopping, or capacity problems. There were indications of scouring along this section which is typical of stream channels with super critical flows. Segment 2: Pipe Flow; From Ravine to outfall into Puget Sound. (400' to 900) Drainage from the ravine is intercepted by two 12-inch diameter cmp pipes. These pipes intercept the flow from the stream channel direct it through the ravine along the south side of the City of Lynnwood Treatment Plant where it flows under the Burlington Northern Railroad tracks and discharges into the Puget sound. The storm drainage from the ravine to the sound consisted of two 12-inch diameter cmp storm Charlotte Gardens Level 1 Downstream Analysis Report January 18, 2004 Page 3 pipes. There were no indications of problems at the time of the inspection including; overtopping, capacity, erosion or scouring along this section. The pipes were clean and the creek channel was at the same level as the invert of the pipes. A limited inspection of the outlets of the pipes indicated no problems at the outfall. This concludes the downstream description. A total distance 900 feet was covered to Puget Sound. TASK 4: CONCLUSIONS AND PROPOSED MITIGATION Level 1 Analysis Conclusions: The total distance covered was 900 feet from the site to the Puget Sound. The Level 1 Analysis indicates that there is little in the way of drainage capacity problems. There were some indications of scouring of the stream channel which is typical of streams with super critical flows. The proposed sub -division is only 2.10 acres in size of which only 1.4 acres will be developed. The total drainage basin, draining to this ravine is 344 acres in size, which makes the site less than 0.6 percent of the total contributing drainage area. The project proposes to mitigate the potential erosion to the steep slopes by tight -lining the un- detained drainage down the steep slopes into the ravine. In addition, the drainage discharge point is located within the City of Lynnwood's drainage basin, where a .previous agreement was reached for direct discharge into the City's drainage basin without detention. Water quality treatment will be provide through the use of a "Stormfilter" water quality vault which will treat the runoff prior to discharge from the site. Therefore, the proposed development should have little if any impact on downstream conditions.

In preparing this report,' AC Roth Environmental Consultants (RES) has used site information and survey mapping of RES wetland flag locations provided by Lovell-Sauerland and Associates, as referenced herein. Findings reported herein are based on information gathered in the field at the time of investigation by RES, RES's understanding of 1997 Washington State Wetlands Identification and Delineation Manual (Ecology 1997), and RES's understanding of federal, state and local regulations governing wetland and stream areas. Prior to preliminary and final design or any construction, all appropriate regulatory agencies should be contacted to verify the findings of this report, and to obtain appropriate approvals and permits. The wetland boundary, wetland, and stream classification and recommended buffers are RES's best professional opinion based on the circumstances and site conditions at the time of its study. The final wetland boundary determination, classification of wetlands and streams, and the required buffers and setbacks are subject to change by the appropriate federal, state, and local jurisdiction. Critical Areas Study Talbot Paris Estates Introduction 1. Introduction The subject property is an approximate 2 acre site located at 7701 171" Street SW, Edmonds, Washington, near the intersection of 171" Street and Sea Lawn Drive. From discussion with the City, the applicant proposes to develop the site for a single family residential development. The purpose of this report is to present a third -party analysis of site water resources, consistent with the requirements of the City of Edmonds Critical Areas (Edmonds Municipal Code [EMC] §20.15B). A series of consultants have evaluated this and a property to the west. A May 31, 2002 Wetland Evaluation was prepared by Terra Associates for a property located at 17015 Talbot Road (Attachment A). This property's easterly boundary forms the westerly segment of the subject property's northwestern corner. Terra Associates found a wetland which was indicated to extend easterly onto the subject property, but the offsite wetland area was unsurveyed. A June 3, 2002 Critical Area Reconnaissance Report (Attachment B) was prepared by Wetland Resources, Inc. evaluated the "potential presence of jurisdictional wetlands" on the subject property. This "forested and scrub -shrub wetland" was sketched as approximately 1800 square feet in area. It does not appear that a survey of this evaluation was performed. In February of 2003, Pentec Environmental prepared a report entitled Third -Party Review of Critical Areas Study of the Talbot Park Estates (Attachment C), on behalf of the City. In the absence of a prior formal delineation of wetlands on the subject property, Pentec Environmental conducted a "preliminary wetland delineation of the onsite portion of the wetland". Using GPS survey methods to establish approximate location of delineated wetland boundaries, the conclusion of this last report was that the onsite and offsite portions of the wetland appear to total 2,700 square feet, but that more careful delineation and complete survey of the wetland boundary would need to be conducted. Critical Areas Study Talbot Park Estates i Introduction Critical Areas Study Talbot Park Estates Figure 1 Vicinity Map 2 Introduction 2. Water Resources Evaluation 2.1 Introduction On April 2, 2003, RES staff performed on -site investigations to determine the presence, type and extent of water resources on the subject property. The primary objectives of the site evaluations were: 1) the identification of any streams and wetlands under the jurisdiction of the U.S. Army Corps of Engineers (Corps); and 2) the delineation of all water resources subject. to land use review and regulation by EMC § 20.15B. On -site water resources include approximately 1,374 SF of scrub -shrub and emergent wetlands located in the northwest corner of the Taylor Park site and extending to the west (Figure 3). The total size of the wetland is approximately 4,485 SF. A stream enters the site at its southeast corner and flows in a northerly direction near the east property boundary. Under Section 404 of the Clean Water Act, the ACOE has jurisdiction over the waters of the United States, including streams, lakes, ponds and wetlands. If no fill of water resources is anticipated, direct contact with ACOE is not required and the City of Edmonds would be the lead regulatory agency for site permitting. 2.2 Wetlands 2.2.1 Methodology Prior to conducting field evaluation, a number of sources were consulted. The National Wetland Inventory,(NWI) has evaluated wetlands throughout the Stanwood area, using the system described in Classification of Wetlands and Deepwater Habitats of the United States (Cowardin 1979). The NWI mapping, as portrayed at http://www.nwi.fws.gov/,,fails to identify any wetlands or streams on or in the vicinity of the subject site. Soils on the site have been mapped as the Alderwood-Everett gravelly sandy loam and Alderwood-Urban land series by the USDA Soil Conservation Service (SCS). Neither of these is listed as a hydric soil on the Official Hydric Soils List for Snohomish County (SCS, 1994). To perform the wetland delineation for the site, the 1997 Washington State Wetlands Identification and Delineation Manual (Ecology 1997) was used.

Side Map Critical Areas Study 4 Talbot Park Estates Water Resources Evaluation The methodology in this manual recognizes that the three parameters of hydrology and wetland plants are generally found in wetlands and that these parameters are important in the establishment and maintenance of wetland.communities. Within the methodology, indicators are evaluated in the field to determine satisfaction of each of the three parameters for establishment of wetland boundaries: 1. Hydrophytic Plants - The US Fish and Wildlife Service (Reed, 1988 and 1993) has established a rating system which has been applied to commonly occurring plant species on the basis of their frequency of occurrence in wetlands. Species indicator status expresses the range that plants may occur in wetlands and non -wetlands (uplands). Within the State and federal methodology, satisfaction of the hydrophytic plant community criterion occurs when the plant community is comprised of 50 percent or more of the dominant species which are adapted to or tolerant of saturated soil conditions: an indicator status of facultative (FAQ, facultative wetland (FACW), or obligate (OBL) wetland (Table 1). Modifiers are used with the indicator categories to more specifically define the frequency of occurrence. A positive (+) sign indicates plants are more frequently found in wetlands than the category indicates, whereas a negative (-) sign indicates plants are less frequently found in wetlands than the indicator signifies. A status of FAC- does not meet the hydrophytic plant community criterion. 2. Hydrology - Evidence of permanent or periodic inundation, or (at least) soil saturation to within 12 inches of the surface for one week or more during the growing season (soil temperatures above 41 OF); indicators other than standing water or soil saturation include stained leaves, soil surficial cracking or water -borne litter. 3. Hydric soils - Soils that are saturated, flooded, or ponded enough during the growing season to develop anaerobic conditions in the upper soil horizons, or to the depth of 12 to 18 inches; indicators include high organic content, low soil chroma (Munsell' matrix chroma of 2 with mottles or less than 2 without mottles) or gleying. 1 Munsell Soil Color Charts, Kollmorgan Instruments Corporation, Baltimore, Maryland Critical Areas Study Talbot Park Estates Water Resources Evaluation Table 1. USFWS Plant Indicator Status Obligate Upland UPL Occur rarely in wetlands (less than 99 percent) and almost always in uplands (greater than 99 percent) .Facultative Upland FACU Occur rarely in.wetlands (less than 99 percent) and almost always in uplands (greater than 99 percent) Facultative FAC Equal likelihood in uplands and wetlands (33 to 67 percent) .

At several locations which supported uniform or homogeneous plant cover within the delineated wetland areas, sample plots (Appendix A) were established for recording of wetland characteristics and for an assessment of wetland. functions, including those described in Table 2. 2.2.2 Investigation Results RES conducted a site. visit in April2003, concurrent with surveyors from Lovell:Sauerland and Associates, to determine the presence, type and extent of critical areas (wetlands and streams) on the subject property.

The on -site water resource is a 0.032 acre portion (Figures 3, 4, and 5) of a larger (0.10 acre) scrub -shrub and emergent, seasonally flooded/saturated wetland, as classified by Cowardin, et al. (1979). The wetland is found in a shallow depression on the northeast corner of the subject property and extends to the west, onto an adjacent property. Figure 3. Emergent Wetland at west boundary, looking into the property from the west. Note emergent zone and standing water. The wetland on the site has no overstory and the shrub layer is principally comprised of Sitka willow (Salix sitchensis, FACW), salmonberry (Rubus spectabilis, FAC+), and red alder (Alnus rubra, FAQ, with some Himalayan blackberry (Rubus discolor, FACU) cover entering the wetland area. Other than sparse creeping buttercup (Ranunculus repens, FACW) and occasional (Juncus effusus, FACW), the herb layer throughout the majority of the fringing scrub -shrub zone is absent. The vegetation in the more central emergent area, in which standing water was 1 to 2 inches deep at the time of evaluation, was dominated by Pacific water parsley Critical Areas Study g Talbot Park Estates _ S {` � 1 `I k JI +, ���•grw'Ri �rt`3 �\ ��T �.ifiS \ � `� Water Resources Evaluation (Oenanthe sarmentosa, OBL). The predominance of the vegetation supports the hydric vegetation criterion. Surface soils range from very dark grayish brown (IOYR 3/2) silt to silt loam with dark yellowish brown (10YR 4/6) mottles in the upper 12 to 18 inches at the wetland boundary, to black (IOYR 2/1) very organic loam in the interior of the wetland. Similar to the findings of Pentec, distinct change in soil color and change in topography separated wetlands from uplands, with soil colors of dark yellowish brown 10YR 3/3 and 10YR 3/4. Soil colors support satisfaction of the hydric soils criterion. Hydrologic support for the wetland are shallow subsurface flows. At the time of April 2003 sampling, the soil saturation at the wetland boundary was at a depth of 8 inches; standing water in the more central portions of the wetland was between 2 and 3 inches. Satisfaction of the hydrology criterion for these locations was based on soil saturation and presence of standing water. Therefore; all criteria are met for consideration of the delineated area as a wetland, satisfying the conditions of EDC §20.15B.130B. No wildlife associated with this resource, other than typical songbirds, was noted at the time of site investigation. Due to its small size and location in an urbanized area, the wetland area on the site serves limited functions for hydrologic, water quality, and wildlife support, including habitat. Limited hydrologic support functions include stream baseflow contribution. In terms of water quality functions, values are low for sediment/shoreline stabilization and low for retention/transformation of sediments, nutrients, or toxicants. Natural biological functions are similarly low in value, including primary productivity, detrital transport, nutrient cycling/utdization, and food. chain support. Habitat functions are low for all species but amphibians and insects. Socioeconomic functions are limited to aesthetic, which are judged to below, largely based on size and location of the wetland. Since the wetland is greater than 2,500 square feet in area, it is regulated by the City (EMC §20.15B.020.TT). The wetland is classified as a Category 3 wetland (EMC §20.15B.060), since it is equal to or less than 1 acre and greater than 2,500 square feet and that has one wetland class. Under EMC §20.15B.130C, 25 foot buffers are required. Critical Areas Study 10 Talbot Park Estates Water Resources Evaluation 2.3 Stream Critical Areas. Study Talbot Park Estates A stream locally referred to as Outfall Creek (Terra Associates 2002) enters the site at its southeast corner and flows in a northerly direction near the east property boundary. The approximate stream bank boundaries and the centerline are found in Figure 2 and documents submitted by LSA in May 2002. In agreement with Pentec's findings, the stream should be classified as a Category 2 stream under EMC 20.15B.060. Due to barriers, this stream is not used by salmonids and would therefore be buffered on either side by 25 foot buffers (EMC 20.15B.120). In April 2003, RES measured the width of the stream at various locations along its course, and is in agreement with Pentec's estimate that the average width is 30 inches, yielding an average width west of centerline of 15 inches. 11 Bibliography 3.

The property is located in the northeast* quarter of Section 7, Township 27 North, and Range 4 East. The site is roughly rectangular and approximately 0.21 acres (Figure 2). Talbot Road borders the site to the west. Properties to the north and south, as well as most of the neighborhood, are developed with single- family residences. The property to the east is undeveloped and forested. The subject property is. developed with a single-family residence. The house, driveway, and residential landscaping are located on the northern half of the property. The southern half is undeveloped. The southern area appears to be a tributary drainage that likely flows towards an unnamed creek to the east (this creek is unofficially named "Outfall Creek" on the Snohomish County orthophotographs for this section). - METHODS For the purpose of Ihis study, we used the wetland definition adopted by the Environmental Protection Agency (EPA)' and the Army Corps of Engineers (COE) for administering Section 404. of the 1977 Clean Water Act. According to this definition, wetlands are: Those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps; marshes, bogs, and similar areas.

May 31, 2002 All of the test pits contained a gravelly sandy soil with a topsoil layer between five to eight inches deep. The topsoil layer was highly organic in nature with a matrix: color of IOYR'2/1. Soils below the topsoil were mostly lacking in organic material. Matrix colors ranged from 10YR 3/1 (Test Pit TP-1) to 7.5 YR 4/6 (Test. Pit TP-4). Soils with a low chroma value (/1 or /2 if redoxymorphic features are :present) are generally considered to be hydric. . Redoxymorphic features (iron masses, nodules, reductions, or depletions) were present in Test Pits.TP-1, TP-2, and TP 3, and absent in Test Pit TP4. Redoxymorphic features develop when soils _are saturated long enough during the growing season for iron and manganese to biologically transform from an oxidized form to a reduced form. Soils in Test Pits TP-1, TP-2, and TP-3 satisfied the hydric soils criteria. Surface water was not present at the time of our site.visit. However, there was ample evidence of recent standing water. Organic topsoil was exposed over part of subject site.. No evidence of leaf litter existed in the area of exposed topsoil. We observed watermarks on a downed big -leaf maple (Acer macrophyllum) tree and brightly colored rust on the bottom two inches of the wire fence and fence posts that delineate the eastern border of the subject property. We also observed free water in Test Pits TP-1 and TP-3, but not in Test Pits TP-2 or TP4. Primary and secondary evidence indicates the presence of wetland hydrology at Test. Pits TP-1 and TP-3. VEGETATION Vegetation on the subject property forms three distinct communities. The vegetation community on the northern half of the property is urban landscape. The southern half of the property is mostly second -growth forest and scrub -shrub. This forested portion is dominated by big -leaf maple, red alder (Alnus rubra), and black cottonwood (Populus trichocarpa), suggesting an upland habitat. The third community in the southeast corner of the property is -dominated by salmonberry (Rubus spectabilis), Scouler's willow (Salix scouleriana), Pacific willow (Salix lasiandra), and red,alder; suggesting a'wetland habitat. Other common shrub species presentin the area include Indian plum (Oemleria cerasiformis), Himalayan blackberry (Rubus discolor), common hawthorn (Crataegus monogyna), red elderberry (Sambucus racemosa), English holly (Ilex aguifolium);. and English laurel (Prunus laurocerasus). Herb species included cleavers (Gallium appraise), lady fem (Athyrium filiz femina), sword fern (Polystichum munitum), 'creeping buttercup (Ranunculus repens), fringecup (Tellima grandiflora), and herb Robert (Geranium robertianum). WETLAND DETERMINATION An area of wetland conditions exists in the southeast corner of the subject .property (Figure 3). Wetland conditions continue off -site to the east.. The approximate area of this wetland on the subject' property is 1,600 square feet., The determination of wetland conditions was based on patterns of vegetation,. soil conditions, and field hydrology. The. size of this wetland was estimated by plotting distance and bearing measurements taken in the field. Property boundaries were estimated based on in -field. measurements. The flagged wetland boundary and property boundary should be professionally surveyed for accuracy.

Q°y Lynnwood, WA 98036 P CRITICAL AREA RECONNAISSANCE REPORT TALBOT PARK ESTATES CITY OF EDMONDS - SNOHOMISH COUNTY,' WA Welland Resources, Inc., completed a site investigation on June 3, 2002 to evaluate the potential presence of jurisdictional wetlands on an approximate 2 acre site located immediately north of the intersection of Sea Lawn Drive and 17 V St. SW in the city of Edmonds, WA. The site lies as a portion of Sec. 7, Twp. 27N, Rae. 4E, W.M. The Washington State Department of Ecology Wetlands Identification and Delineation Manual (March 1997) was used to evaluate site conditions. Critical area protection regulations were obtained using the City of Edmonds Ordinance Chapter 20.1513 Critical Areas. Site Description The subject property is bounded to the south by 171" St. SW, to the west and north by single family residences and on the'east by a forested slope. The south one -quarter of the property contains an existing single family residence with associated out buildings. The central portion of the property is a mix of grassland and forest. The north end of the property is forested with immature red alder. The topography of the site is sloping to the north and east. Wetlands One small forested and scrub/shrub wetland was located along the western property boundary. The on -site portion of the wetland is approximately 500 square feet in size. The off -site portion of the wetland is approximately 1,200 square feet in size. The total area of the entire wetland is approximately 1,700 square feet. Wetlands less than 2,500 square feet in size are not regulated in the city of Edmonds (EMC 20.15B.020 TT). Wetland boundaries were reasonably distinct based on soil color and dominance of wetland vegetation. The off -site portion of the wetland was estimated by observation done while looking over the existing property fence. The off -site portion of the wetland boundary appears to have been flagged in the recent past. Dominant wetland vegetation contained in this wetland includes twinberry, creeping buttercup, and salmonberry. Wetland Resources, Inc.

Anchorage Boston Re: Third -Party Review of Critical Areas Study of the Talbot Park Estates Pentec #12130-15 Chicago Dear Steve: At the request of the City of Edmonds, Pentec conducted a third -party review of the Critical Denver Areas Study of the proposed Talbot Park Estates.at 7707 - 17151 Street SW, Edmonds, Washington. This review includes a review of wetland boundaries and the measurement of the width of the stream along the east property boundary..) reviewed the Critical Area Reconnaissance report (CAR) prepared for the property by Wetland Resources, Inc., dated June 3, 2002, and a wetland report for the adjacent property to the west. I also reviewed a Fairbanks Wetland Evaluation (WE) report dated May 31, 2002, prepared for the adjacent property to the northwest by Terra Associates, Inc. also In addition, I conducted a site inspection on January 29, 2003. WETLAND Jersey City The 2-acre site contains a portion of a small wetland toward the northwest corner. The wetland is bisected by the site's west property boundary. Although there are a few small trees in the wetland it classifies as a palustrine scrub -shrub wetland following the U.S. Fish Juneau and Wildlife Services' Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al 1979).. Dominant plants in the wetland include salmonberry (Rubus spectabi/is), Sitka willow (Sa/ixsitchenis), red alder (Alms rubra), ladyfern (Athyrium Alix-femina), and creeping buttercup (Ranunculus repens). See attached photos of wetland. Long Beach WETLAND BOUNDARY On the day of the site inspection only a single piece of pink "wetland delineation" flagging was located. The flagging was toward.the center of the wetland and did not have anything written on it. Two pieces of orange flagging (also without writing) were located on the west Portland property fence. These two flags .were close to the wetland edge, and it is assumed that they were tied by Wetland Resources during the site reconnaissance. A large maple tree had A Division of Hart Crowser, Inc.

A City of Edmonds 12130-15 February 28, 2003 Page 3 : Based on -the 2,700-sf estimate, this wetland is larger than the 2,500-sf threshold in Section 20.4513.20 of the Edmonds Critical Areas Ordinance (CAO) and would be a regulated feature. Based on Section 20.15B.060 of the CAO the wetland is classified as a Category 3 wetland because it is less than 1 acre and has only one vegetation class. STREAM A stream runs through the northeast corner of the site and near the east property boundary. The centerline of the stream is shown on the CAR map and the Preliminary Plat drawing (Lovell-Sauerland & Associates 4294-0-01 May 29, 2002). Based on Pentec's site visit it is i assumed the stream is perennial and would therefore be classified as a.Category 2 stream by the CAO (20.15B.060).. A 25-foot buffer is required on both sides of Category 2 streams without salmonids and a 50-foot buffer is required on both sides of a Category 2 stream with salmonids. The CAO (20.1 5B.1 20) specifies stream buffers to be measured outward from the top of bank. Pentec measured the width of the stream (between stream banks) at five locations along the stream. These measurements were made to provide the City with a means of evaluating the . stream setback requirements relative to the stream centerline shown on the Preliminary Plat drawing. On the reach of the stream east of the site the width between the banks is on average 30 inches. Based on this estimate the west bank of the stream is on average 15 inches from the stream centerline.
