. , � � Technical Memorandum—Habitat Assessment for Holly Drive Lift Station Upgrade December 23, 2015 downstream of the project area. Finally, bull trout are known to be present in the Sammamish River, but they do not ascend Swamp Creek and do not come within approximately 10 miles of the project area. The proposed lift station upgrade project will implement BMPs for the control of sedimentation and erosion, and the three species of salmonids occurring in the vicinity do not ascend Swamp Creek beyond Lake Stickney about 2 miles downstream of the project area. Operation of the improved Holly Drive Lift Station will maintain current levels of wastewater treatment from the District and City of Everett service areas to protect habitat in Puget Sound. Any change in water quality and habitat in Swamp Creek will not be observable or measurable more than 1/2 mile downstream of the proj ect area. Therefore, the proposed Holly Drive Lift Station Upgrade project will have no effect on Puget Sound Chinook salmon, Puget Sound steelhead, and Puget Sound bull trout. Terrestrial Species Evaluation The U.S. Fish and Wildlife Service Information, Planning, and Consultation Database (IPaC) Official Species List for the Holly Drive Lift Station Upgrade included the following terrestrial species: • Marbled Murrelet • Streaked Horned Lark • Yellow-Billed Cuckoo • Canada Lynx Further, the Official Species List indicated that there are no designated critical habitats on, or adjacent to,the project area. Marbled Murrelet The marbled murrelet is a small sea bird that nests in old-growth forest areas within 50 miles of marine waters in Washington. Nests tend to be located in old-growth trees near significant stream corridors, which facilitate daily feeding migrations from the nest to marine waters. The project area is along a headwater portion of Swamp Creek and the area surrounding the lift station has been developed as a residential neighborhood for many years. The WDFW Priority Habitat and Species online database did not identify any marbled murrelet nesting areas within 2 miles of the proposed project site. It is unlikely that marbled murrelets utilizing the Sammamish River as a flight corridor from the Cascade foothills would detour out of their way several miles to the project area, as there is no suitable nesting or feeding habitat nearby. Therefore, the presence of the � �� A
