Mr. Mike McGlothlin P� ge 2 August 2, 1991 Wetlands Delineation The water resource flowing northerly across the eastern quarter of the parcel is the headwaters to Pigeon Point Creek No. 2; it apparently drains the area to the south, including the commercial uses along SR 99 to the southeast on the above site. See the attached figure for portrayal of the resource in relationship to property boundaries and site topography. At each of four representative stations along the creek, data plots were established to locate the boundary between wetlands and adjacent uplands. Soils were evaluated using a hand auger and an assessment or the deoth to soil saturation was made. Presence of hydric or wetland vegetation was recorded. Soils at the site's wetland/upland interface were 10YR 2/1 black to 10YR 2/2 very dark brown sandy loam and at the time of evaluation, depth to saturation was between 9 and 16 inches. Salmonberry (Rubus spectabilis) formed the dominant component of the shrub layer, with lesser constituents in the form of lady -fern (Athyrium filix-femina). Small red alder (Alnus rubra) and Oregon ash (Fraxinus latifolia) formed the overstory at the western wetland edge. The upland vegetation is represented by ten to twenty year old Douglas -fir (Pseudotsuga menziesir), western redcedar (Thuja plicata) and western hemlock (Tsuga heterophylla), with English holly (flex sp.), sword -fern (Polysticchum munitum), trailing/Pacific blackberry (Rubus ursinus) and salal (Gaultheria shallon) forming the understory. Under the current City of Everett Zoning Code Ordinance, Environmentally Sensitive Areas (Section 37.090), this riparian corridor wetland would be rated as a Category II wetland. Wetland Functional Values As a creek with a forested edge, acting as the headwaters to Pigeon Point Creek No. 2, the wetland resource on the site provides moderate hydrologic values as a collection and disrhrrge channel; although the creek is narrow through a ravine in this area in the muibL of ar, urban area, due to the presence of a forested edge, biological values are moderate for support of insects, birds and other small invertebrates. Native Growth Buffers As a Category II wetland, the Zoning Code (Section 37.100) specifies a minimum buffer requirement of 50 feet for single family development and 75 feet for multiple family development. Upon the adoption the revised Environmentally Sensitive Areas section of the Everett Zoning Code, anticipated to occur prior to September 1991, the buffer width will increase to 75 feet. For your review, I have indicated each of these buffer widths on the attached figure.
