Re: Farrelli’s Soils Report for Design Infiltration Rates
Site Address: 813 W Yelm Avenue, Yelm, Washington 98597
Parcel Number: 21724130700
Dear Ms. Hodges:
At your request, I have prepared this soils report. A site visit was performed on 8/9/21 to assess site
conditions.
The subject site consists of a previously developed lot with an existing restaurant and small parking lot on
the east half of the parcel.
The surrounding area consists of commercial properties. The lot is located on the west side of Yelm
Highway.
The site topography is generally sloping from the east to west. The approximately 1.61 acre (Per Thurston
County Assessor data) property is vegetated with grass.
The United States Natural Resource Conservation Service maps the soils in the area as Spanaway
gravelly sandy loam. These soils are listed as Type A soils. No groundwater or mottling was observed in
any of the test pits.
The project is not located in an aquifer recharge area or a wellhead protection area as defined by the
Grays Harbor County Health Department, the EPA or by the county. There are no known ravines, or
wetlands located on the site. There are no known basin plans for the area. Refer to the attachments for
applicable Soils Maps.
The Washington Geologic Information Portal lists the onsite soils as the following:
GEOLOGIC_UNIT_LABEL:Qgd
GEOLOGIC_UNIT_DESC:Pleistocene till and outwash clay, silt, sand, gravel, cobbles, and boulders
deposited by or originating from continental glaciers; locally includes peat, nonglacial sediments, modified
land, and artificial fill.
GEOLOGIC_UNIT_POLY_500K_ID:14608
GEOLOGIC_AGE:Quaternary (Pleistocene)

Each of the test pits were observed to determine soil infiltration feasibility. It appeared to have soils
consistent with USDA soils maps. There did not appear to be groundwater or mottling for the depth of the
test pit. Based upon the attached sieve tests the soils worst case soils that were encountered was
consistent with a gravel with sand soil type.
Based upon Method 2 Soil Property Relationships Method an infiltration rate of 20 inches per hour and a
design infiltration rate of 10 inches per hour should be used for an infiltration design for project.
Once again, thank you for the opportunity to work with you on this project. Please feel free to give me a
call if you have any questions.

Warning: Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause
misunderstanding of the detail of mapping and accuracy of soil
line placement. The maps do not show the small areas of
contrasting soils that could have been shown at a more detailed
scale.
Please rely on the bar scale on each map sheet for map
measurements.

Web Soil Survey URL:
Coordinate System: Web Mercator (EPSG:3857)
Maps from the Web Soil Survey are based on the Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more
accurate calculations of distance or area are required.
This product is generated from the USDA-NRCS certified data as
of the version date(s) listed below.
Soil Survey Area: Thurston County Area, Washington
Survey Area Data: Version 14, Jun 4, 2020
Soil map units are labeled (as space allows) for map scales
1:50,000 or larger.
Date(s) aerial images were photographed: Jul 18, 2020—Jul 20,
2020
The orthophoto or other base map on which the soil lines were
compiled and digitized probably differs from the background
imagery displayed on these maps. As a result, some minor
shifting of map unit boundaries may be evident.
