k Findings & Conclusions <br /> 3/1/02 <br /> Page 16 <br /> 5.1). Alternatively, a project proponent may rescore the site using that model to <br /> reflect existing conditions: <br /> • Fourth quartile (highest quality)—0.75 acre for each acre lost <br /> • Third quartile (moderate quality)—0.5 acre for each acre lost <br /> • Second quartile (fair quality) —0.3 acre for each acre lost <br /> • First quartile (lowest quality)—0.1 acre for each acre lost <br /> No compensation shall be required for vegetated freshwater wetlands lost through <br /> restoration of tidal functions, if the restoration project is not used as compensatory <br /> mitigation. <br /> 1997 SEWIP Regulations (Apply to palustrine compensation only) <br /> The following mitigation ratios apply only to the development footprint identified in <br /> figure 2.3 A in SEWIP. (The new language is needed in order to distinguish between <br /> development footprints added to SEWIP without review by the SEWIP Review <br /> Committee.) <br /> G.1 Unavoidable Impacts. Unavoidable impacts to wetland functions in the <br /> Snohomish River Estuary shall be compensated by restoring historic wetlands in <br /> the Estuary identified in the restoration plans (Table 2.1 and Chapter 5). <br /> G.1B. Where Compensation Can Occur. Compensation for impacts to <br /> vegetated palustrine wetlands may occur within the same Ecological Management <br /> Unit or within the adjacent Ecological Management Unit (See EMU Map, Figure <br /> 2.2). <br /> G.2. Minimum Compensation Requirements. The minimum requirements for <br /> compensation will be one acre of restored wetland for one acre of wetland lost. <br /> G.3A. How Compensation is Calculated. The acreage of compensation shall be <br /> calculated from the IVA function performance scores using the following ratio, <br /> provided that the minimum compensation requirement of regulation G.2 is met <br /> (see Figure 2.4 for example): <br /> IVA score for per acre function lost X(1.25) X(acres lost) = Acreage of <br /> IVA score for per acre function gained <br /> Compensa <br /> tion <br /> This regulation applies when the restoration credits are less than the impact debits <br /> and the calculated "Acreage of Compensation" will not be less than the acreage loss; <br /> otherwise regulation G.2 should be applied. The 1.25 multiplier is included in this <br /> ratio calculation to compensate for the temporal loss of wetland functions at the <br />
