3.2.2 Wetland B Cowardin Classification: Palustrine, Forested Wetland, Broad-leaved Deciduous, Saturated WA Dept. of Ecology Rating: Category III, Habitat Score 13 City of Everett Rating: Category III City of Everett Buffer Requirement: 60-foot buffer Figures 3 & 4: Views of Wetland B Wetland B is located in the Southeastern portion of the subject property. Wetland B is a depressional wetland with no outlet. It is primarily dominated by a forested vegetation community. 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 B received a total score of 35, with a habitat score of 13 on the DOE Wetland Rating Form for Western Washington. In the city of Everett, wetlands that receive between 30 and 50 points are classified as Category III wetlands. Category III wetlands with a habitat score of 13 receive a buffer width of 60 feet. ' Vegetation in this wetland is represented by the following observed species: no forested species rooted within the wetland itself, however an overstory of red alder overhangs the wetland boundary. Salmonberry dominates the fringes of the wetland with creeping buttercup (Ranunculus ' repens, FacW) present in the herbaceous layer. The dominance of species rated "Facultative" and wetter meets the criteria for hydrophytic vegetation. ' Typical soils within Wetland B were moist to saturated at the surface at the time of inspection. Sampled soils were found to be dark gray (IOYR 3/ 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 B meets all criteria for designation as a wetland. CriticalArea Study 7 WRI# 15202 ' Soundview Business Campus Rev. #2: October 2, 2015
