Table 37.1: Mitigation Measures 3. All projects must include and integrate mitigation 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 measures must be included in the wetland study required by this chapter. Additionally, at a minimum the analysis shall address the potential land use impacts identified in Table 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. SECTION 4: Subsection C of Section 11 of Ordinance 2909-06 (EMC 19.37.110), which reads as follows: C. Standard Buffer Width Reduction for Category IV Wetlands. Buffer reductions are allowed; provided, that the applicant demonstrates the proposal meets criteria in subsections C.1 through C.3 and either CA or C.5 of this section. If the criteria are met, buffers may be reduced by up to twenty-five percent or no less than twenty-six feet. 1. The buffer area has less than fifteen percent slopes, the existing buffer provides minimal vegetative cover and cannot provide the minimum water quality or habitat functions, and enhancement is proposed consistent with the following criteria: a. A mitigation plan consistent with Sections 37.120.1), E and F is approved by the director, including, but not limited to, maintenance, monitoring and provisions for an assurance device; b. The plan shall include plant densities not less than five feet on center for shrubs and ten feet on center for trees; 2. A site-specific evaluation and documentation of buffer adequacy is based on consideration of the best available science and special consideration for the conservation or protection measures necessary to preserve or enhance anadromous fisheries consistent with WAC 365-195-900 through 365-195-925; and 3. Buffer width averaging is not utilized; and either 11 Activities and Uses Examples of That Cause Disturbance Disturbance Examples of Measures to Minimize Impacts regime surfaces Management Manual for Western Washington (2005) • Lawns • Tilling Pets and human • Residential areas • Use fencing; plant dense vegetation to delineate buffer edge and disturbance to discourage disturbance using vegetation appropriate for the Puget Lowland ecoregion; place wetland and its buffer in a separate tract Dust • 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.
