2.2.2 Non -wetland area <br />Vegetation within the non -wetland areas of the site includes Himalayan blackberry (Rubus <br />anneniacus; FAC), reed canarygrass (Phalanx arundinacea; FACW), and bentgrass (Agrostis sp.; FAC). <br />Soils from 0 to 10 inches are generally very dark grayish brown (10YR 3/2) silt. From 10 to 18 <br />inches soils are dark grayish brown (2.5Y 4/2) silt with 10 percent dark yellowish brown (10 YR <br />4/6) redoximorphic features. This soil profile displays a hydric soil indicator of Depleted Matrix <br />(F3). No wetland hydrology indicators were met at the time of our site visit. <br />3.0 WETLAND FUNCTIONS AND VALUES ASSESSMENT <br />Methodology <br />The methodology for this functions and values assessment is based on professional opinion <br />developed through past field analyses and interpretation. This assessment pertains specifically to <br />this site but is typical for assessments of similar systems common to western Washington. <br />Functions and Values — Professional Opinion <br />Wetlands in western Washington perform a variety of ecosystem functions. Included among the <br />most important functions provided by wetlands are stonmwater control, water quality <br />improvement, fish and wildlife habitat, aesthetic value, recreational opportunities, and education. <br />Assessments of these functions for the project site are provided below. <br />Existing Conditions <br />The on -site wetland provides a low level of functions for all values. This wetland has limited native <br />vegetation density and diversity and is on a slope. Slope wetlands lacking dense woody species <br />have limited ability to control stormwater flows and provided water quality treatment. The level <br />of functions provided by this wetland is limited by its relatively small size, the lack of dense native <br />species, its location on a slope, and the intensity of the surrounding development. <br />4.0 SUMMARY OF RESULTS <br />One Palustrine Scrub -shrub wetland (Wetland A) was identified on the subject property. Wetland <br />A is classified as a Category IV wetland under the 2014 DOE Wetland Rating System for Western <br />Washington.
