Vegetation within the wetland is dominated by Western red cedar (Thin aplicata, FAC), red alder (Alnus rubra, FAC), salmonberry (Rubus spectabilis, FAC), bittersweet nightshade (Solanum dulcamara, FAC), lady fern(Athyrium filix femina, FAC), and skunk cabbage (Lysichiton americanus, OBL). According to the NRCS, the soils on the subject site consist of Alderwood-Urban land complex, 2 to 8 percent slopes. The Alderwood-Urban series is described as moderately deep and moderately well drained. The average annual precipitation is 40 inches. Permeability of this soil is moderately rapid above the hardpan and very slow through it. Included in this soil unit are Everett, Ragnar, Indianola, McKenna, and Norma soils, and Terric Medisaprists. McKenna and Norma soils and Terric Medisaprists are listed on the Snohomish County hydric soils list. During our investigation, we observed that soils in the wetland have a Munsell color of black (10YR 2/1) to a depth of at least 24 inches with a texture of sandy loam and having some organic content. At the time of the site visit on April 27, 2016, the soil in the wetland was saturated to the surface. Based on our field observations, it appears that the areas shown as wetland meet the criteria for hydric vegetation, soils and hydrology. Vegetation outside the wetland includes Western red cedar (Thuja plicata, FAC), red alder (Alnus rubra, FAC), Himalayan blackberry (Rubus armeniacus, FAC), and red elderberry (Sambucus racemosa, FACU). Soils outside the wetland had a color of very dark brown (10YR 2/2) in the upper 6 inches and a color of dark brown (10YR 3/3) from 6 to 16 inches depth. The soil had a texture of gravelly sandy loam throughout the soil profile and was moist at the time of our site investigation. The wetland is a Category IV wetland, receiving a score of 13 on the Western Washington Wetland Rating System form with a habitat score of 5. Category IV wetlands with a habitat score of 5 or greater receive 44-foot buffers. The off-site stream is shown on the City of Everett Critical Areas Map as a Type Ns stream. The on-site stream buffer is dominated by native vegetation with a component of invasive species present including Himalayan blackberry (Rubus armeniacus) and English holly (Ilex aquifolium). As mature native vegetation is dominant in the buffer, pursuant to EMC 19.37.170, Type Ns streams with buffers of intact native vegetation receive a 50-foot buffer. 4.3 WETLAND AND STREAM CLASSIFICATIONS—COWARDIN Based on the Cowardin wetland classification system (Cowardin 1979), the on-site wetland and off-site stream are classified as follows: Stream A: Riverine,Upper Perennial, Unconsolidated Bottom,Mud Wetland A: Palustrine, Forested,Needle-leaved evergreen, Saturated View Ridge Community Church 4 Critical Area Report and Buffer WRI#16092 Averaging/Enhancement Plan November 21,2016
