• <br /> 13 <br /> determine the required "overall compensation acreage2"in order to ensure that the <br /> limiting function is adequately compensated for. Excess compensation acreage3 for the <br /> non-limiting function shall not be available as compensation for other wetland impacts. <br /> 5. When to Use Average Restoration Potential Per Acre. An average restoration potential <br /> per acre shall be used to establish the compensation requirements in cases where several <br /> wetland complexes are restored simultaneously(as in a compensation bank). This <br /> average is to be calculated by summing the potential increase in IVA acre-points for each <br /> group of functions and dividing by the total acreage of the site. This average shall then <br /> be used to determine the acres of compensation required according to regulations 35.B. 2 <br /> or 3. <br /> 6. SEWIP Restoration Plan is a Guide for Objectives and Goals. The SEWIP restoration <br /> plan for an individual site must be used as the basis for setting the goals and objectives of <br /> any compensation proposed. <br /> 7. Guidelines for Developing Compensatory Mitigation Plans. Compensatory mitigation <br /> plans with applicable performance standards submitted under the SEWIP plan should <br /> follow the interagency"Guidelines for Developing Freshwater Wetlands Mitigation Plans <br /> and Proposals" (Department of Ecology Publication #94-29, 40 pp). <br /> 7a. Threatened, Endangered or Commercially Important Species. If areas in the development <br /> footprint have SEWIP-mapped "threatened, endangered or commercially important <br /> species,"then the compensation plan shall incorporate design measures to mitigate any <br /> impacts to these species. (See 1997 SEWIP Figures 2.5 and 2.6.) SETOC will amend the <br /> Plan to incorporate any new mapped areas of threatened, endangered or commercially <br /> important species. If a COE regional permit is adopted, then the amendment process <br /> must meet the requirements of that permit. <br /> 8. Use of Restoration Acreage in Lieu of Maintenance & Contingency Bond. The <br /> restoration of additional wetland acreage may be used in lieu of a maintenance and <br /> contingency bond4. The area of this "in-kind"maintenance and contingency bond will be <br /> equal to the area required for compensation (one additional acre of restoration for every <br /> acre needed as compensation). Wetlands that are restored/enhanced for the maintenance <br /> and contingency bond may be used or sold by the applicant to compensate for other <br /> impacts when all the five-year performance standards established in the mitigation plan <br /> are met. Separate bonds for monitoring shall be required. <br /> 2"Overall Compensation Acreage"shall be defined as the required acreage of compensation calculated from regulation G.3 for the <br /> limiting group of functions(e.g.either Water Quality Improvement or Habitat). <br /> 3"Excess Compensation Acreage"is when the calculated acreage of compensation for the"non-limiting"group of functions is <br /> subtracted from the"Overall Compensation Acreage." <br /> 4 The maintenance bond would be used to ensure restoration goals and objectives are met and may include maintenance actions <br /> such as control of invasive species,watering of plants,and maintenance of any installed structures,such as inlet and outlet <br /> structures.The contingency bond would be used to provide for correction of design deficiencies identified through monitoring of <br /> hydrology,soils and wetland and buffer plantings and ensure attainment of the restoration goals and objectives. <br /> 99 <br /> 34 <br />
