3.2.3 Wetland C Cowardin Classification: Palustrine, Forested Wetland, Broad-leaved Deciduous, Saturated WA Dept. of Ecology Rating: Category II, Habitat Score 19 City of Everett Rating: Category II City of Everett Buffer Requirement: 75-foot buffer Figures 5 & 6: Views of Wetland C Wetland C is located in the Southeastern portion of the subject property. Wetland C is a depressional wetland with no outlet. Forested vegetation dominates Wetland C. This wetland is part of a wetland mosaic existing in the southeastern corner of the site. The primary source of hydrology to the wetland complex is surface flows from the south. Wetland C received a total score of 51, with a habitat score of 19 on the DOE Wetland Rating Form for Western Washington. In the city of Everett, wetlands that receive between 51 and 69 points are classified as Category II wetlands. Category II wetlands with a habitat score of 19 receive a buffer width of 75 feet. Vegetation in this wetland is represented by the following observed species: Western red cedar dominates the overstory of the wetland with an understory being by salmonberry and lady fern (Athyrium filix femina, Fac) along the wetland fringe. The dominance of species rated "Facultative" and wetter meets the criteria for hydrophytic vegetation. Typical soils within Wetland C were ponded at the surface at the time of inspection. Sampled soils were found to be dark gray (2.5Y 2/1) from 0 to 18 inches below the surface, and sandy -silt in texture. The wetland area, as mapped, appears to satisfy the criteria for hydric soils. Soils sampled in the wetland were moist with dark chromas, inferring the presence of water at or near the surface for at least 12.5 percent of the growing season. This satisfies wetland hydrology criteria. Wetland C meets all criteria for designation as a wetland. Critical Area Study 8 WRI# 15202 Soundview Business Campus Rev. #2: October 2, 2015 '
