compensation (i.e., which is the limiting function) will determine the required overall compensation acreage in order to ensure that the limiting function is adequately compensated for. Excess compensation acreage for the nonlimiting function shall not be available as compensation for other habitat impacts. 9. Use of Average Restoration Potential Per Acre. An average restoration potential per acre shall be used to establish the compensation requirements in cases where several AUs are restored simultaneously (as in a compensation bank) or where several individual project impacts are to be mitigated in a single restoration project. This average is calculated by summing the potential increase in IVA-acre points and dividing by the total acreage of the site. This average shall then be used to determine the acres of compensation required according to Regulations 35.A. 3 and 6 or 7. 10. Guidelines for Developing Compensatory Mitigation Plans. Compensatory mitigation and monitoring plans (CMMPs) with applicable performance standards submitted under the SEWIP plan should follow the interagency "Guidelines for Developing Freshwater Wetlands Mitigation Plans and Proposals" (Department of Ecology Publication #94-29), which is subject to amendment by Department of Ecology and future acceptance by the City. CMMPs shall be circulated to the SSOTAC for review and comment and for adaptive management purposes as provided in Salmon Overlay Section 5.6. Applicants should consider the overall restoration objectives set forth in SO Chapter 6. 11. Performance Criteria. Standards and performance criteria shall be established for each mitigation action as described in SO Section 5.6 and stated in the CMMP. 12. Monitoring Requirements. Each compensation site shall be monitored over a period of up to10 years as described in SO Section 5.6. 13. Threatened, Endangered, or Commercially Important Species. All tidal and associated riparian areas within the SEWIP planning area are designated critical habitat for chinook salmon and are likely to also constitute important habitat for coho salmon and anadromous native char. If areas in the UGA have other threatened, endangered or commercially important species,then the compensation plan shall incorporate design measures to mitigate any impacts to these species and their habitats. 14. Projects with Impacts Outside of the Estuary Study Area. Projects with impacts outside of the SEWIP study area may be compensated for within the SEWIP study area, consistent with the SEWIP restoration and/or enhancement goals and objectives. 15. Loss of Palustrine Wetlands. Compensation is required where existing palustrine wetlands will be converted to tidal habitat for compensatory mitigation. The acreages calculated per this regulation are set aside within the restored mitigation site and may not be considered as compensatory mitigation. However, to provide an incentive to developers to undertake tidal restoration as compensatory mitigation, while recognizing the range of functions provided by different types of isolated palustrine wetlands, the 38
