A Level I Wetland Assessment was conducted on April 27, 2005 to determine the presence of
wetlands and wetland buffers near a proposed building site. The Jefferson County Critical Areas Map
indicates a wetland complex associated with a Type 5 stream on the southern portion of the 20-acre
parcel. The proposed building site is located on the eastern edge of the parcel.
Wetland analysis was conducted using the methodology outlined in the Washington State Department
of Ecology Wetland Identification and Delineation Manual (1997). All wetlands within Jefferson
County are subject to requirements outlined in the Jefferson County Unified Development Code
(lJDC) dated January I, 2001. Land use restrictions will apply to all future developments associated
with this parcel that are located near the wetlands.
Description of Site
· Legal Description: Parcel #801 003004 Section 3 Township 28N Range 1 W
· Location: 5343 West Valley Road, Jefferson County
· Soils: Ale Alderwood gravelly sandy loam, and Mm McMurray and Mukilteo peats (Hydric
soils) Slopes: 0 to 15% slopes
Findings
The location for the single-family residence is at the top -of a hill and outside th~ wetland complex and
the associated buffers. There is an unmapped seasonal stream (Type 5) downslope and approximately
140 feet from the proposed building location. Buffers assigned to a Type 5 stream are 50 feet. Soils
within perk holes excavated near the building envelope did not qualify as hydric soils (IOYR 4/4 with
faint mottles in the upper portion). This building site will not impact wetlands or wetland buffers.
Final authority over wetland or stream determinations and associated buffers rests with Jefferson
County Planning Department.
