SITE DESCRIPTION Wetland Resources, Inc. completed a site investigation and delineation in March, 2008, to locate and evaluate jurisdictional wetlands and streams on and in the vicinity of a 35.74- acre site. It is located on the east side of 36th Ave West, north of Seaway Boulevard, in the city of Everett, Washington (Section 3, Township 28N, Range 4E, W.M.). The subject property is undeveloped and forested throughout. Topography is variable, with steep east aspect slopes in the eastern portion of the property and slightly rolling topography throughout the remainder of the site. Surrounding land use is comprised of a commercial development to the north (Intermec Corp.) with undeveloped forested areas to the east, south and west. Current zoning of the site is M-M Business Park. There are six wetlands and two Type Ns streams located on the subject site. The wetlands are identified as Wetlands A through F on the attached maps. Wetland A is located in the northern central portion of the property and extends off -site to the north. Wetlands B, C and D are located off -site to the north on the Intermec Technologies Corp. campus. Wetland E is located along the northern property boundary of the subject site adjacent to the Intermec Campus parking lot. Wetland F, which contains two Type Ns streams, is located in the northeastern corner of the subject property. The two on -site streams drain into Powder Mill Gulch, located off -site to the west. The reach of Powder Mill Gulch adjacent to the site is mapped on the City of Everett Critical Areas Map 1 as a Type F stream. The Washington State Department of Ecology's (DOE) Washington State Wetland Rating System for Western Washington (Revised) was used to classify the wetlands associated with this site. DOE's Washington State Wetland Rating Form for Western Washington (Version 2) was completed for each wetland. Rating forms and mapping are included as an appendix to this report. Based on the classifications and point totals achieved from the rating system, Everett Municipal Code, Chapter 37, was applied to determine wetland buffer widths. Wetlands A-D and F are classified as Category III wetlands under the rating system, with habitat scores below 19 points, and thereby receive 60-foot buffers in Everett. Wetland E is classified as a Category II wetland with less than 19 habitat points and thereby receives a 75-foot buffer. Since the site is composed of intact, native vegetation, both Type Ns streams that lie within Wetland F receive 50-foot buffers and the off -site Type F stream (Powder Mill Gulch) is designated a 100-foot buffer. PROPOSED DEVELOPMENT AND MITIGATION MEASURES Development History The subject property (Lot 2) was master planned in the late 1980's for a building very similar to the Intermec Corp. building on the adjacent lot (Lot 1). It was identified as Phase 3 of the Intermec Corporate Headquarters on the Master Site Plan. The planned building on Lot 2 was rotated 90 degrees and access was proposed from Intermec's current access road off of 36th Avenue West. Construction access for Lot 1 was provided across Lot 2 in the vicinity of the current location of Wetland A. Intermec Technologies Corp. ultimately decided not to pursue the previously planned development of Lot 2. Signs of construction disturbance are still visible on Lot 2 and likely contributed to the creation of Wetlands A through D.
