This will allow the lift station to continue functioning effectively for the next <br /> 20 years and will help the District and the City of Everett to avoid emergency responses <br /> and repairs to the lift station (and potential contamination of Swamp Creek)that would be <br /> likely to occur if the existing aging equipment were not replaced at this time. <br /> Implementation of the proposed lift station improvements will provide capacity to extend <br /> sewers to areas currently served by on-site septic systems. <br /> CONCLUSIONS AND EFFECT DETERMINATIONS <br /> The Holly Drive Lift Station Upgrade project will occur approximately 2 miles above the <br /> nearest known habitat for Puget Sound Chinook salmon and Puget Sound steelhead, and <br /> more than 10 miles above habitat for Puget Sound bull trout in the Sammamish River. <br /> Further, best management practices for the control of sedimentation and erosion will be <br /> implemented during construction of the proposed wet well and associated electrical <br /> equipment, pumps, and pipes within the existing lift station fence line. Therefore, the <br /> proposed Holly Drive Lift Station Upgrade project will have no effect on the following <br /> aquatic species protected under the Endangered Species Act: <br /> • Puget Sound Chinook Salmon <br /> • Puget Sound Steelhead <br /> • Puget Sound Bull Trout <br /> Further, as ground disturbance will be limited to the area within the existing lift station <br /> fence line and noise associated with the project will be short term and unlikely to be <br /> audible 1/2 mile from the project area, the project will have no effect on the following <br /> ESA-listed terrestrial species ar their critical habitats: <br /> • Marbled Murrelet <br /> • Streaked Horned Lark <br /> • Yellow-Billed Cuckoo <br /> • Canada Lynx <br /> REFERENCES <br /> City of Everett, 2009.
