STREAM CLASSIFICATIONS — CITY OF EVERETT Under the City of Everett Critical Areas Regulations (CAR), Chapter 37, the streams on the subject site are classified as follows: Glenwood Creek, Type Np Stream: Located in the eastern portion of the subject site, this perennial stream is greater than two feet wide and has a gradient of less than sixteen percent on the subject site. However, it is mapped as Type Np on the City of Everett Critical Areas Map 1 and is not known by either the Washington State Department of Fish and Wildlife or Snohomish County to be fish bearing. In the City of Everett, Type Np streams with buffers comprised of intact native vegetation typically receive a standard buffer width of 50-feet. Unnamed Tributary to Glenwood Creek, Type Ns Stream: Located in the western portion of the subject site, this intermittent tributary is two feet wide or less and has a gradient of more than sixteen percent on portions of the subject site. This stream is mapped as Type Ns on the City of Everett Critical Areas Map 1. In the City of Everett, Type Ns streams with buffers comprised of intact native vegetation typically receive a standard buffer width of 50-feet. HABITAT ASSESSMENT While it is possible that portions of Glenwood Creek support some species of fish, no listed species are known to occur in the vicinity of the subject site. There are no known bald eagle nests in the project vicinity and no anadromous fish based on the Washington Department of Fish and Wildlife Priority Habitat and Species maps and Snohomish County fish distribution maps. Anadromous fish are likely excluded from this stream by impassible gradients in the downstream reaches. Vegetation in the forested portions of the property is represented by a canopy of western red cedar (Thuja plicata, Fac), Douglas fir (Pseudotsuga menziesii, FacU), and red alder (Alnus rubra, Fac), with salmonberry (Rubus spectabilis, Fac+) and sword fern (Polystichum munitum, FacU) dominant in the understory. Vegetation in the wetlands associated with the subject streams is represented by a canopy of western red cedar and red alder, with stink currant (Ribes bracteosum, Fac+), lady fern (Athyrium filix-femina, Fac), skunk cabbage (Lysichiton americanum, Obl), and piggy-back plant (Tolmiea menziesii, Fac) in the understory. The critical areas on the subject site are in relatively good condition and provide moderate values for all assessed functions. The forested buffers adjacent to the on-site wetlands and streams provide habitat functions, including stream shading, bank stability, large woody debris recruitment, bank stabilization, sediment control, wildlife habitat, and deposition of allochthonous material to the stream.
