The City of Everett Wetland and Stream Inventory identifies Merrill and Ring Creek off -site at the base of the deep ravine. This creek has known salmonid use and is therefore classified as a Type F. Type F streams are typically designated 150-foot protected buffers. When the required buffer falls on a slope greater than 25 percent, the buffer shall be the greater of the prescribed buffer (150 feet) or 25 feet beyond the point where the slope is less than 25 percent. In addition, wetland areas are also depicted off -site adjacent to the Creek. An off -site investigation was not conducted to verify the presence of wetlands or to prepare any associated rating forms. For a detailed description of the Geologically hazardous areas, please refer to the Geotechnical Engineering Evaluation prepared by Nelson Geotechnical Associates, Inc, September 15, 2009. It is my understanding that the tree removal occurred within the buffer of Ring and Merrill Creek and in the Erosion and Landslide Hazard Areas. 2.2 KNOwN HISTORIC OR CULTURAL RESOURCES ON THE DEVELOPMENT SITE There are no known historic or cultural resources on the development site. 2.3 DESCRIPTION OF THE WATER REGIME The off -site wetland, associated with the F stream, is likely a hydrogeomorphic class slope wetland (based on available topography). The wetland is classified under the Cowardin classification system as a Palustrine, Forested Wetland, Broad-leaved Deciduous, Saturated; the on -site stream is classified under Cowardin as Riverine, Upper Perennial, Unconsolidated bottom The source of hydrology for both the wetland and the stream appears to be a shallow groundwater table and seasonal runoff. 2.4 DESCRIPTION OF THE SOILS The soils underlying the site are mapped in the Soil Survey of Snohomis,. County Area Washington as Alderwood-Urban land complex, 2 to 8 percent slopes. Aldelwood-Urban land complex, 25 to 70 perce 1t slopes: This unit is about 60 percent Alderwood gravelly sandy loam and about 25 percent Everett gravelly sandy loam. Included in this unit are small areas of McKenna and Norma soils and Terric Medisaprists in depressional areas and drainz.ge ways on plains. Also included are small areas of soils that are very '_'h_-;!nw raver a hardpan; small areas of Everett, Indianola, and Ragnar soils on teraces and outwash plains; and soils that have a stony and bouldery surface layer. Included areas make up about 15 percent of the total acreage. Alderwood soil is moderately deep over a hardpan and is moderately well drained. It formed in glacial till. Typically the surface layer is very dark grayish brown gravelly sandy loam about 7 inches thick. The upper part of the subsoil is dark yellowish brown and dark brown very gravelly sandy loam about 23 inches thick.
