Standard Buffer: Unvegetated; Standard Buffer: Sparsely Vegetated; Stream Classification Intact Native or Vegetated with (Type) Vegetation Invasive Species 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 'I. 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 stream 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 nationsnative tribes; 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 outstanding actual or potential habitat for those species, or has unusual nesting or resting sites such as heron rookeries or raptor nesting or lookout trees; 4. The land adjacent to the stream and its associated buffer is classified as a geologically hazardous or unstable area; 5. Increased buffer width is necessary to effectively include the riparian corridor of the stream. 19.37.145 — Standard Stream and Lake Buffer Width Reduction with Enhancement. The planning director may, using the review process as described in EMC Title 15, Local Project Review Procedures, reduce the standard stream buffer width only when there has previously been substantial legal alteration of the stream and/or buffer on the subject lot or adjoining lots resulting in the existing buffer being unvegetated, sparsely vegetated, or vegetated with nonnative invasive species and when buffer enhancement is provided per the following criteria. Where buffer reduction with enhancement is permitted by this chapter, it shall be limited to portions of buffers that have minimal functions due to prior legal alteration.
