Methodology:
This report provides calculations for the design of an onsite infiltration trench for the developed
impervious surface of the Tract 999 access drive. Calculations comply with the City of Edmond's
design criteria of the 1998 King County Surface Water Design Manual (KCSWDM). An infiltration
rate was determined through field testing by Associated Earth Sciences, Inc. Please refer to that
report under separate cover for details. The rates found were very high, but in compliance with
KCSWDM the maximum rate of 20 inches per hour was used in the calculations as recommended
by Associated Earth Sciences, Inc. The impervious area was calculated from the site plan provided
by the Developer has been included in this report.
Calculations:
Solve for Required Trench Length:
L = [(0.054 x Ploo x A,) / (10 x Im)] / (trench surface area)
Given:
L = ? (solve for length of trench)
Pioo = 3.0 in (100-year precipitation)
Ar = 4,000 sf (3,177 sf + 823 sf contingency)
Im = 0.333 in/min. (20 in/hr per soils -engineer)
Trench surface area = 3' + 3' + 3' = 9' (see Figure 1)
L = f(O.054 x 3 x 4,000)/ (10 x 0.333)] / (9) = 22'of trench

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

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.

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.

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.

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

development of this short plat, please do not hesitate to call.
