A Levell Wetland Assessment was conducted on. August 29,2006 to
wetland bufferthat may restrict development on the subject parcel. The
single family home with a conventional septic system. Wetlands are indicated on
Critical Areas Maps for this parcel.
Fieldwork to determine the actual wetland boundaries was conducted according to the
methodology outlined in the Washington State Wetland Identification and Delineation Manual
(Department of Ecology #96-94) and Jefferson County Unified Development Code (UDC) dated
January 1,2001.
Description of Site
· Legal Description: Parcel #997 600 008 Section 8 Township 30N Range 1 W
· Location: 434 S. Jacob Miller Road, Jefferson County
· Soils: CfC Cassolary sandy loam and AgB Agnew silt loam
. Slopes: 0 to 15% slopes
Findings
The subject parcel and surrounding area is in open pasture and home sites. Strangers Lake, a
documented pond to the north of the site, has been dry since 2001. Although a wetland is
mapped on the subject parcel, findings show that only a small remnant of this larger wetland
remains. Please refer to the map, included with this letter, with the Jefferson County wetland
map areas and the aerial map from 2005 which clearly shows the isolated wetland identified in
the field. There is no apparent overland connection to Strangers Lake or adjacent wetlands,

The small wetland was identified by a slight drop in elevation and wetland soils (lOYR 2/1).
Wetland vegetation identified included the following water dependent species (OBL, F ACW
and FACW+) Ladysthumb Polygonum amphibium, Foxtail Alopecurus sp.(geniculatus?), Curly
dock Rumex crispus, and Reed canarygrass Phalaris arundinacea. The presence of these
species indicates a regular high water table, All vegetation was stressed due to late summer
drought. According to Mimi Jennson this area was saturated during the rainy season,
The wetland measured approximately 100' X 60' (approximately 6,000 square feet) and will
most likely qualify as a Category III or IV wetland. Under the current Jefferson County Unified
Development Code, wetlands of this size are not regulated, The proposed development is
within the western portion of the parcel whereas the small wetland is on the eastern edge. The
proposed septic site (indicated by perk holes) and homesite are over 200 and 400 feet,
respectively, from the isolated wetland.
Final authority over wetland determinations and associated buffers rests with Jefferson County
Department of Community Development. If this project requires delineation or if you have
further planning needs please don't hesitate to call.
