top of the bank or ordinary high water mark shall be determined so as to include the entire stream feature. 2. The standard buffer widths required by this chapter presume the existence of a relatively intact native vegetated community including native tree cover, shrub understory and ground cover. If the existing buffer is unvegetated, sparsely vegetated, or vegetated with invasive species,the buffer width shall be increased as required by this section. 3. Except as otherwise provided by Section 19.37.050 of this chapter,the following minimum buffers of native vegetation shall apply to streams based upon stream classification: Table 37.5:Stream Buffers Standard Buffer: Unvegetated; Standard Buffer: Sparsely Vegetated; Stream Classification Intact Native or Vegetated with (Type) Vegetation Invasive Species Type S Buffer determined by requirements of by requirements of city of Everett city of Everett shoreline master shoreline master program (SMP)100 program (SMP)150 feet feet Type F 100 feet 150 feet Type Np 50 feet 75 feet Type Ns 50 feet 75 feet 1. To maintain the integrity of the buffer, buildings and other structures shall be set back a minimum of ten feet from the edges of all strum buffer boundaries. B. Standard Buffer Width Increase.The city shall require increased buffer widths as necessary to protect streams when the stream is particularly sensitive to disturbance, or the development poses unusual impacts and the increased buffer width is necessary to protect the critical areas described in this subsection. Circumstances which may require buffers beyond minimum requirements include, but are not limited to,the following: 1. When the minimum buffer for a stream extends into an area with a slope of greater than twenty- five percent,the buffer shall be the greater of: a. The minimum buffer for that particular stream; or b. Twenty-five feet beyond the point where the slope becomes twenty-five percent or less; 2. The stream reach affected by the development proposal serves as critical fish habitat for spawning or rearing as determined by the city using information from resource agencies including, but not limited to,the Washington State Department of Fish and Wildlife, U.S. Fish and Wildlife Service, and recognized tribal nationsn es; 3. The stream or adjacent riparian corridor is used by species listed by the federal government or the state as endangered,threatened, rare,sensitive,or monitored, or provides critical or EMC Title 19.37 (Critical Areas) Page 46
