The standard buffer widths required by this chapter presume the existence of a relatively <br />intact native vegetated community including native tree cover, shrub understory and ground <br />cover. If the existing buffer is unvegetated, sparsely vegetated, or vegetated with invasive <br />species, the buffer vegetation shall be enhanced or restored to the width required by this <br />section. The vegetation shall include native plant communities that are appropriate for the <br />Puget Lowland ecoregion or with a plant community that provides similar functions. <br />B. Increased Standard Wetland Buffer Width. The minimum buffer width stated in subsection A of this <br />section shall be increased: <br />1. When the minimum buffer for a wetland extends into an area with a slope of greater than <br />twenty-five percent, the buffer shall be the greater of: <br />a. The minimum buffer for that particular wetland; or <br />b. Twenty-five feet beyond the point where the slope becomes twenty-five percent or <br />less for at least a horizontal distance of ten feet; <br />2. When the wetland is used by salmonids, plant and/or animal species proposed or listed by <br />the federal government or state as endangered, threatened, rare, candidate, sensitive or <br />monitored; or has critical or outstanding potential habitat for those species or has unusual <br />nesting or resting sites such as heron rookeries or raptor nesting trees, and the increased buffer <br />is necessary to protect such habitat; <br />3. When a habitat assessment or habitat management plan is required by EMC 19.37.190 and <br />an increased buffer is necessary to protect critical habitat or affected species, the buffer shall be <br />the buffer in the approved habitat assessment or habitat management plan; <br />4. When the adjacent land is classified as a geologically hazardous area, the buffer shall be the <br />greater of the standard wetland buffer or the setback buffer required by EMC 19.37.080; <br />5. When the standard buffer has minimal or degraded vegetative cover that cannot be <br />improved through enhancement; or
