2.O DESCRIPTION OF THE DEVELOPMENT SITE BASELINE CONDITIONS) The site is undeveloped and located in an area of existing commercial and residential development. Mature forest is present on the steep slope located in the southwest corner of the property as well as in the southeastern corner of the site, which contains a wetland mosaic comprised of three wetlands. The remainder of the site, which makes up the majority, was clear- cut in 2006 and is currently vegetated by scrub -shrub communities due to the resultant succession. With the exception of the southwestern portion of the site, the subject property displays a general northern aspect. Surrounding land use is comprised of a commercial development to the east (Intermec Corp.), residential development to the north and northeast, and forested areas to the west and south. The Boeing railroad spur lies just west of the site. Current zoning of the site is M-1 Office and Industrial Park. The study area contains two Category II wetlands (Wetlands A and C) and two Category III wetlands (Wetland B and D) (Washington Department of Ecology (DOE) and City of Everett classifications). Photographs and wetland rating forms are included in the Critical Area Study, Appendix C of the Biological Evaluation. Edgewater Creek and Japanese Gulch Creek both receive drainage from the project site, and are both within a half -mile of the site. There are currently four drainage areas existing onsite, as shown in Figure 3. The western -most portion of the site to be developed (Pre -Basin A) drains down the steep slope along the western border and in the southwestern corner of the site, and subsequently into Japanese Gulch. The northwestern drainage area (Pre -Basin B) drains north into an intersecting ravine, which leads into a series of several existing stormwater conveyance features that eventually discharge into the ravine above Edgewater Creek. The northeastern drainage area (Pre -Basin C) drains to the northeast into a ravine that shallows out and is intersected by a drainage ditch leading into Edgewater Creek. The southeastern drainage area (Pre -Basin D) contains Wetlands A-C, and is hydrologically sourced from the off -site area to the south (Pre -Basin C Run -On). Runoff currently outlets from Wetland A into a catch basin, under 36th Avenue W, flowing to an existing stormwater conveyance ditch on the neighboring property.
