GeoSource Engineering, Inc. received via e-mail the City of Edmond's review
comments dated 8/6/2008 reviewed by Jerry Shuster, P.E. I also spoke with him on
the phone about what additional information would be acceptable to him for his
approval of the storm water drainage design. This addendum letter address his
comments per his requi.rements of our phone conversation.
Impervious Areas
My runoff calculations used both the existing and new impervious areas totaling 5525
sq. ft. Attached are revised calculations using only the new impervious areas of 1760
sq. ft.
Applicability of Infiltration Trenches
Mr. Shuster states that infiltration is not allowed because of the location shown on a
City map. Maps are general in nature and always subject to site -specific field
verification by a Professional Geologist. In the case of your property, the geologic map
(U.S. Geological Survey) indicates the base soil to be Glacial Till (Soil Conservation
Service [SCS] designation Everett Gravelly Sandy Loam: EvB; an agricultural
classification system which is of little use to engineers). "TREET FILE

C080702 Greg Ward Residence, Storm water review responses, 8/20/2008, Page 2 of 4
Due to being deposited in a glacial environment the Till is often overlain by a deposit of
glacial outwash soils known as Alluvium. Engineers use the Unified Soils
Classification system which designates the upper Alluvium deposit on your site as SW:
well -graded gravelly sand based on standard laboratory sieve testing. For a
discussion of the methodology of sieve testing the reader is directed to American
Society for Testing Materials ASTM:D421-58.
Our lab sieve tests results for the two test holes averaged 15% gravel (greater than #4
sieve), 80. 1 % sand, and 4.9% silt (less than #200 sieve). The reason sieve tests are
used over the old method of pouring water into a hole and timing how fast it flows into
the soils ("perk" test) is that the preferred sieve tests yield the overall average grain -
size distribution (from which a direct infiltration rate may be read) and are unaffected
by environmental factors such as outside temperature, soil saturation, and time of the
year.
The situation on your property is such that the Till is overlain by 3 feet of a slightly silty
sand with considerable gravel (Alluvium). While the Till has a low infiltration rate, the
Alluvium has a good rate. Our sieve testing/grain-size distribution results indicates an
infiltration rate of 0.01cm/sec (4 minutes/inch) which is determined by index values
given in either of two principal geotechnical engineering texts: Standard Handbook for
Civil Engineers, Fred Merritt, 1976, p.7-8 and Soil Mechanics in Engineering Practice,
Terzaghi & Peck, 1967, p. 381. We have used these charts for over 25 years without
any problems. Even so, The City's Engineer is requiring a dispersion trench which is
an infiltration trench with the gravel backfill open to the air. With this type of system,
any water that is not infiltrated into the soils will flow out the top of the trench onto the
lawn as surface drainage to the west.
In our opinion, an underground detention tank system for this small, residential site is
very costly and unnecessary for the small volume of runoff from 1760 sq. ft. of
impervious area.
Highest Ground Water Level
We do not anticipate the development of any high ground water table which would
affect infiltration due to the sloping nature of the Till. The sloping Till will naturally drain
infiltrated water to the west as it always has. It is impossible to build up a standing
ground water table atop a sloping impermeable surface such as the Till.
infiltration Design Methodology
As mentioned, the methodology for determining infiltration rates in both King and
Snohomish Counties has been the grain -size distribution method (ASTM:D421) using
the previously -mentioned engineering index properties charts.
The calculations for sizing the infiltration/dispersion trench are based on the widely -
accepted Rational Method which has been specified in the King County Surface Water
Design Manual for decades. This method is best suited to determine storm water
volume from impervious surfaces.

Dear Greg:
GeoSource Engineering, Inc. made a visit to the abovementioned site to dig subsurface exploration
holes and take soil samples. The purpose of our visit was to determine infiltration rates and complete
an infiltration trench design for the new additions. The intention is to infiltrate runoff into a trench on
the western portion of the property. The locations of our exploration holes are shown on the attached
Site and Exploration Plan — Fig. 1.
Authorization Conditions
Authorization to proceed with this study was granted by Greg Ward. This report has been prepared
for the exclusive use of Greg Ward and his agents, for specific application to this property. Within the
limitations of scope, schedule and budget, our services have been performed in accordance with
generally accepted geotechnical engineering and engineering geology practices in effect in this area
at the time our report was prepared. No other warranty, expressed or implied is made. Our
observations, findings, and opinions are a means to reduce the geotechnical risks inherent to owning
or developing property.
GEOLOGIC CONDITIONS
Geologic conditions on the lot was observed from our test holes. The observed soils consisted of the
following (from top to bottom):

Alluvium - Underlying the topsoil the soils consisted of a relatively thin veneer of medium
dense sand with gravel classified as Alluvium. This material extended down to 3 feet in
depth and was formed by weathering of the underlying denser soils.
Glacial Till - This material was overrun by several thousand feet of ice during the last
glacial advance (Vashon age) which resulted in a compact soil possessing high strength,
low compressibility, and low permeability characteristics where undisturbed. In many
places however, the top 2 to 4 feet has typically been weathered to a looser condition. Till
commonly consists of very dense, moist, gray, silty, gravelly, fine to coarse sand with
occasional cobbles and larger rocks.
HIGHEST GROUND WATER LEVEL
We do not anticipate the development of any high ground water table due to the sloping nature of the
Till. The sloping Till will naturally drain infiltrated water to the west.
INFILTRATION RATES
Our engineering assessment indicates the following infiltration rates:
Test Hole No. Lot No. Infiltration Rate
1 1 4.1 min/in.
2 3 3.9 min/in.
Based on the average infiltration rate of 4.0 minutes/inch we have performed engineering calculations
to size and design the infiltration trench. Our design is shown on the attached design drawing.
We appreciate this opportunity to be of service. If you should have any questions, please do not
hesitate to call.
