emergent, scrub shrub and open water habitat would be created. The intent is to significantly improve the habitat functions. I The detailed wetland mitigation plan/report must demonstrate that wildlife habitat will be significantly improved by the proposed mitigation and that raising the outlet elevation will not result in degradation of the existing wetland. Mitigation must also be designed to ensure that stability of adjacent slopes is not impacted and that the mitigation will not adversely impact adjacent or downstream properties. Acquisition of properties containing wetlands that would otherwise be filled in order to permit reasonable use of the property, rather than constructing compensation/mitigation. The Planning Director must approve the specific wetland site to be acquired. These properties must be permanently protected by deed restrictions, dedication to the City, or other means approved by the Planning Director. If the City establishes a fund to purchase "reasonable use" properties, the applicant may be permitted to contribute to such a fund. The amount of the contribution will be determined per an administrative manual developed at time of creation of the fund. • Mitigation in drainage basins outside of the Study Area may also be approved by the Planning Director, subject to a case-by-case analysis. For example, mitigation may be proposed in the North Creek or Swamp Creek drainage basins, or in the Snohomish River estuary. At this time, there is no scientific basis for trading off wetland functions for "out -of -kind" mitigation (such as creating estuarine wetland to compensate for palustrine or riparian wetlands). Therefore, when out -of -kind mitigation is proposed, mitigation ratios found in Chapter 37 of the Zoning Code shall be doubled at a minimum, with the actual mitigation ratio to be determined by the Planning Director. • If the City or other agency establishes a functioning mitigation bank that is performing wetland functions satisfactorily, the applicant may, subject to a case-by-case approval by the City, be allowed to purchase credits rather than constructing compensation/mitigation. For a City bank, mitigation shall be provided per an administrative manual developed at time of creation of the mitigation bank. If the mitigation bank is established by another agency, mitigation ratios shall be per the City Zoning Code or the agency banking agreement, whichever is greater. (SEPA Land and Shoreline Use, Water, and Plant and Animal Policies) IS AMENDED TO READ AS FOLLOWS: 4.3.4 Mitigating Impacts of Development on Wetlands 1. The wetland mapping completed for the Subarea Plan is not sufficient for purposes of project review (since boundaries were estimated and not delineated and assessment methodologies have changed.). At the time development is proposed on a site containing wetlands, a ' Restricting the outlet can also significantly improve the water quality improvement functions, while also providing some stormwater detention function . However, the mitigation cannot be used to meet required stormwater treatment and detention requirements. 9
