I ISTREAM CLASSIFICATION - CITY OF EVERETT Under the City of Everett's Environmentally Sensitive Areas Ordinance No 1838.91, the on -site stream is classified as following: Category III Stream: This intermittent stream flows for approximately 90 feet along the northeastern border of the subject site before it drains to a catch basin. This stream is naturally intermittent during years of normal rainfall and is not used by salmonids in any portion of the system. Category III streams in the City of Everett typically receive 25-foot protective buffers. 1 SENSITIVE AREA SIGNS Signs shall be placed to permanently mark the boundary of the Environmentally Sensitive Areas. Exact sign language and locations shall be approved by the City of Everett. An example of sensitive area sign language is as follows: ENVIRONMENTALLY SENSITIVE AREA THIS WETLAND AND UPLAND BUFFER ARE PROTECTED TO PROVIDE WILDLIFE HABITAT AND MAINTAIN WATER QUALITY 1 PLEASE DO NOT DISTURB THIS VALUABLE RESOURCE The signs shall be constructed of aluminum or similar durable material. They shall be secured to the minimum 4" X 4" X 7' pressure treated fence posts buried a minimum two feet deep in quick setting concrete. STREAM FUNCTIONS AND VALUES Methodology The methodology for this functions and values assessment is based on professional opinion developed through past field analyses and interpretation. This assessment pertains specifically to the on -site wetland, but is typical for assessments of similar systems common to western Washington. EXISTING CONDITIONS This is a small drainage that appears to only flow during storm events. The stream channel adjacent to the subject site as well as to the north is comprised of a grass lined channel that flows to the on -site catch basin. The buffers of this stream are 1 comprised mainly of lawn with some scattered shrubs. During flood events this stream serves to collect overland flow from adjacent areas and convey it to the on - site catch basin. As a result of the urban location, the lack of established native vegetation in the buffer, the small catchment basin, and the ephemeral nature of this stream, overall functions and values are low. 1 1 2
