Activities and Uses Examples-of That-Cause Disturbance Disturbance - Residential areas - Commercial - Landscaping Change in water - Impermeable - Comply with the Department of Ecology's Stormwater regime surfaces Management Manual for Western Washington (2005) - Lawns - Tilling Pets and human - Residential areas - Use fencing; plant dense vegetation to delineate buffer edge disturbance and to discourage disturbance using vegetation appropriate for the Puget Lowland ecoregion; place wetland and its buffer in a separate tract D- st • Tilled fields - Use best management practices to control dust *Additional mitigation to minimize polluted runoff may be necessary if threatened or endangered species are present at the site. 3. All projects must include and integrate miti_ation of land use impacts into the proposed project Required mitigation measures shall be based upon the site specific analysis required by this section. An analysis of potential impacts and recommended mitigation m asures must be included in the wetland study required by this chapter. 37.1. Mitigation of land use impacts must include, but not be limited to, reasonable mitigation of impacts identified in Table 37.1. In addition,for wetlands that score five or more points for habitat,the study shall include an analysis of existing habitat connections to priority habitats and include measures necessary to maintain those connections as required by subsection A.2 of this section. wetland with mitigation of land use impacts sufficient to reduce buffers down to that required for moderate land use activities. Where a low impact land use is located adjacent to a wetland with a habitat score of nineteen or lower,the buffer width may be reduced by twenty five percent. High, medium and low impact land uses are defined as follows: a. High impact land uses include: commercial, industrial, institutional, retail sales, high intensity recreation (golf courses, ball fields), and residential uses with a density of more than one dwelling unit per acre. b. Moderate impact land uses include residential uses with a density of one unit per acre or less, moderate intensity open space (parks), and paved trails. c. Low impact land uses include: low intensity open space (such as passive recreation and natural resources preservation) and unpaved trails. 5. The buffer for a wetland created, restored, or enhanced as compensation for approved wetland alterations shall be that required for the category of the wetland. 6. 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.
