As requested, the recornmended infiltration rate presented herein is in conformance with the 2005 King County Surface Water Design Manual (King County Manual). Our work has been compl,eted in general accordance with our scope of work letter dated December 12, 2005, and in accordance with generally accepted geotechnical engineering practices in effect at the time of this study. SITE AND PROJECT CONDITIONS The subject property consists of a vacant single lot and a 4-lot short plat located on the east side of the street within the 23900 block of 104' Avenue West in Edmonds, Washington (Figure 1). Two homes currently exist on the short plat parcel; an older, single -story home within the northwest portion of the short plat, which is to'be demolished, and a two-story residence, which is to remain within the southeast portion of the short plat. The single lot has approximately 175 feet of frontage along 104" Avenue West and occupies approximately 0.27 acres. The rectangular -shaped short plat parcel is situated to the east of the single lot and occupies an area of approximately 0.85 acres. Both parcels are relatively flat -lying and at Kirldand 911 Fifth Avenue, Suite 100 - KirkJand. WA 98033 -Phone 425 827-7701 -Fax 425 827-5424 Everett 29111/2 Hewitt Ave.. Suite 2, - Everett.WA 98201 - Phone 425 259-0522 - Fax 425 -252-3408 0 0 approximately . the same elevation as westerly adjacent 104"' Avenue West. It is our understanding that current plans call for construction of a single-family, wood -frame residence on the single lot and on each of the three undeveloped lots within the short plat. The purpose of this study is to evaluate infiltration rates for on -site infiltration of storm water runoff from the lots to be developed. SUBSURFACE CONDITIONS In order to evaluate infiltration rates, infiltration testing was conducted within exploration pits on the single lot and on each of the three lots within the short plat to be developed. The locations of the exploration pits are depicted on the Site and Exploration Plan, Figure 2. Exploration pits EP-1 through EP-4 were initially excavated to a depth of approximately 2 feet at which depth infiltration testing was performed. Immediately after completion of infiltration testing, the exploration pits were excavated to a depth of approximately 10 feet. Conditions encountered in the exploration pits were observed and logged by a geotechnical engineer from our firm. As shown on the attached field logs, approximately 6 to 8 inches of organic topsoil was encountered in our explorations. The upper I inch of the topsoil encountered within exploration pit EP-3 included 1/4-inch crushed rock presumably placed to improve the surface of the driveway. Native sediments encountered below the topsoil layer generally consisted of loose (upper I foot) to medium dense, moist to very moist, light reddish brown (upper 2 feet) to gray, fine to coarse sand with gravel and few cobble. We interpret these native sediments to be representative of Vashon recessional outwash. The Vashon recessional outwash consists of sediments that were deposited by meltwater streams that emanated from the retreating glacial ice during the latter portion of the Vashon Stade of the Fraser Glaciation ending approximately 12,500 years ago. The lower density and light reddish brown color observed in the upper portion of the native stratum is interpreted to be the result of weathering. The Vashon recessional outwash sediments extended beyond the maximum depth of our site exploration. Reference is made to the D.B. Booth, B.F. Cox, K.G. Troost, and S.A. Shimel 2004 composite geologic map of the Sno-King Area, University of Washington, Seattle -Area Geologic Mapping Project, scale 1:24,000. Our interpretation of the sediments encountered in our explorations is in general agreement with the regional geologic map. Hydrology No ground water seepage was encountered during our exploration. It should be noted that the depth and/or occurrence of ground water seepage may vary due to such factors as changes in season, precipitation, and site use. I? INFILTRATION TESTING It is our understanding that current plans call for infiltration of storm water runoff on each of the four lots to be developed. Field infiltration testing was conducted In accordance with the Environmental Protection Agency (EPA) Failing Head Test procedure. Four infiltration tests were conducted, one in each of the four exploration pits excavated as a part of our study. The locations of the exploration pits in which the infiltration tests were conducted are depicted on Figure 2. The EPA Falling Head Test procedure utilizes a 6-inch-diameter pipe driven into the soil to a depth of approximately 6 inches. Two inches of gravel was placed across the surface of the soil exposed within the bottom of the pipe to prevent soil disturbance. The pipe was then filled with approximately 12 to 24 inches of water, measured above the gravel surface using water from a hose bib adjacent to 104'hAvenue West, or an alternate hose bib adjacent to the existing house in the southeastern portion of the site. The water level was maintained within the pipe for at least I hour at each of the test locations. According to the EPA Falling Head Test procedure: "In sandy soils with little or no clay, soaking is not necessary. If afterfilling the hole twice with 12 inches of water, the water seeps completely away in less than 10 minutes, the falling head percolation test can proceed immediately. " In order to determine the need for further soaking of on-slite soils, the pipe was filled with at least 12 inches of clear water and the time for the water to seep completely away was recorded. This was repeated at least 2 times at each infiltration test location. Time recorded for water to seep completely away ranged from approximately 2.9 to 3.0 minutes. Based on this and on the sandy nature of the soil encountered on the site, infiltration testing commenced immediately without further soaking. In preparation for each infiltration test, the pipe is filled with water to a depth of 6 inches above gravel in the bottom of the pipe, and the time required for the water in the pipe to fall each inch for each of the 6 inches is recorded. The infiltration rate for each of the six 1-inch intervals is then averaged. The test is then repeated two additional times. The results of the tests are summarized below in Table 1. Table I Summary of Infiltration Testing Results Infiltration Test No. Depth of Test (feetbgs)* Run No. Infiltration Rate (inches per hour) I (EP-1) 2.0 1 241 2 239 3 237 2 (EP-2) 2.0 1 246 2 242 3 239 3 (EP-3) 2.0 1 244 2 243 3- 241 4 (EP-4) 2.0 1 241 2 240 3 238 * feet bgs = feet below ground surface. 0 0 Following completion of infiltration testing, the infiltration test locations were excavated down to a depth of approximately 10 feet below the existing ground surface to evaluate subsurface conditions below the depth at which the tests were performed. Sediments encountered below the testing depth consisted of recessional outwash sand and gravel to the maximum depth explored. No impervious strata, ground water seepage, or mottling suggestive of seasonal saturation was encountered. CONCLUSIONS Due to scale factors and effects of soil saturation during intense or prolonged storm events, infiltration rates achievable on full-scale infiltration facilities typically are less than those measured during short-term infiltration testing, such as the EPA Falling Head Test. This is due to such factors as ground water mounding, the effect of lateral infiltration during small- scale testing, and the accumulation of fine-grained sediments. The 2005 King County Manual recommends that correction factors be applied to in -situ infiltration measurements to account for uncertainties in testing, depth to the water table or impervious strata, infiltration receptor geometry, and the potential for long-term clogging due to siltation and bio-buildup. This method estimates the maximum design infiltration rate, which must not exceed 20 inches per hour. Table 2 provides the recommended range of correction factors, as taken from the King County Manual. Table 2 Correction Factors Partial Correction Issue Factor Uncertainty in testing method Resting = 0. 5 (large-scale testing) Facility geometry and depth to Fge..,,,y = 0 .25 to I - 0; surface 178mmeiry = 4 D/W +0.05 -water/impervious Potential for long-term clogging due to Fptg&g = 0. 7 to I - 0 siltation and bi2i!�� (depending on soil texture) D = Deoth from facilitv bottom to seasonal hiph water table/ impervious surface. W = Width of facility. The total correction factor applied is the multiple of the partial correction factors in Table 2. The maximum correction factor possible using this method is 0.0875 (0.5 x 0.25 x 0.7). If the maximum correction factor is applied to the field infiltration rates, the resultant recommended design infiltration rates range from 20.8 to 21.3 inches per hour. Therefore, we recommend a design infiltration rate of 20 inches per hour for the facility. The recommended design infiltration rate is based on the soil characteristics at the infiltration test location and depth. Although soil conditions may vary outside this area, they appeared to be fairly consistent at the four exploration pit locations evaluated for this study. If storm water infiltration is to be conducted outside the areas evaluated for this study, we recommend that 11 0 0 Associated Earth Sciences, Inc. verify that subsurface conditions at the proposed infiltration locations are suitable for the recommended infiltration rate. We appreciate this opportunity to have been of service to you with this project. If you should have any questions or require additional geotechnical engineering consultation during design or development of this short plat, please do not hesitate to call.

There are a total of 36 trees planted with there being: Incense Cedar 1 Red Cedar 8 Doug Fir 12 Hemlock 10 Dog Wood 1 Vince Maple 4 for a total of 36 trees. They are not evenly divided but have 17 on 2006-0669, 10 on 2006-0632 and 9 and 2006-0851. The greater number on 2006-0669 is to help screen the church parking lot from the back yard.
