FINAL WETLAND MITIGATION PLAN MUKILTEO SCHOOL DISTRICT NO. 6 CENTRAL FACILITY 1. INTRODUC770N Addition of a proposed central facility with wazehouse, and kitchen, graphics and transportafion offices and associated pazking, along with bus pazking, fueGng and washing facilides and puking for is planned for the eastern 40 percent of a 25 acre pazcel located east of the existing Sno-Isie Skill Center, west of Kasch Park Way and north of the Community Traosit Central Operation Area in the ' City of Everett, Washington; in the SW�/< of the NW'/a of Sec6on 14, Township 28 North, Range 4 East, W.M., Snohomish County, Washington (Figure 1). The September 1992 Wetlands Delineation and Conceptual Mirigaaon Plan, Mukilteo School Dissrict No. 6 Central Facility described habitat and funcaonal values of approximately 111,910 squaze feet (2.569 acres) of weflands on the subject properry, including a wefland appro�cimately 0.976 acres in size which is predominanfly located westerly off-site in the Sno-Isle Skill Center site. This previously submitted report presented a conceptual plan for compensatory mitigation in response to the proposed actual removal of approximately 8,815 squaze feet (0202 acres) of weflands due to coastruction; an addiuonal 3,540 square feet(0.081 acres) of weUands were to be retained in azeas otherwise to be set aside for assceiated 50 foot wetland buffers. Subsequent negofiations between the City and the Architect, Finley/Architecu resulted in a modified site plan which avoided impacts to all but two low-value we2lands comprising 0.095 acres. As conceptually approved by the City of Everett, for the wetlands proposed for removal, compensatory mitigation will be provided in the form of on-site creation of 0.289 acres of wedands in an area adjacent to Wedand E, southwest of the development azea. This final miugafion plan refines and elaborates on elements of the Wetlandr Delineation and Conceptual Mitigarion Plan, including a discussion of specific mitigation goais and objectives, conswction plans and specificaaons for construcaon and planting methods, construction management, performance standazds, a monitoring and contingency program and performance security. 2. WETLAND PROJECT EFFECTS AND FINAL MITLGAT70N PLAN 2.1 Introduction As a result of project construcfion, and with preliminazy approval of the City of Everett, approximately 0.095 acres of weUands will be removed. The proposed final mitigation plan refines an approved conceptual design which will create wetlands in compensauon for unavoidable losses in wetland functional value due to project construction.
