quality control for any toxicants / pollutants that may reach the wetland or adjacent lake. Due to its landscape context (along a lakeshore), the wetland tolerates fluctuating hydrology levels from the lake and aids with reducing the effects of erosion to human-created structures and activities along the lake. Furthermore, the dense vegetation and adsorbent soils serve to trap sediment and pollutants and provide increased water quality functions to aid in a reduction of sediment which results in cleaner water down- gradient of the project site. Wetlands often contain important wildlife habitat resources such as food, water, thermal cover, and hiding cover in close proximity. As evidenced by the score of 5 for Habitat Functions on the Wetland Rating Form, the wetland provides a relatively low level of habitat for wildlife species. The wetland contains two dominant vegetative classes and species, a moderate level of habitat interspersion, and special habitat features such as large woody debris and signs of recent beaver activity. However, the overall wildlife habitat functions among the wetland is reduced due to the high-intensity land use in the vicinity and proximity to roadways that support daily human traffic. As areas become further populated with humans and many habitat areas become fragmented, the protected habitat provided by wetlands and associated buffers becomes increasingly important. Silver Lake provides important habitat for many fish and wildlife species. Per review of the Priority Habitats and Species (PHS), the lake provides documented habitat for Yuma myotis (Myotis yumanensis) and Little Brown Bat (Myotis lucifugus). The lake is also mapped as a waterfowl concentration area which provides habitat for many avian species, particularly birds that require open water components for specific life history requirements. The Everett Shoreline Master Program (2019) states that coho salmon (Oncorhynchus kisutch) historically used the lake, Northern red-legged frogs likely inhabit wetlands around the lake, and triploid rainbow trout (Oncorhynchus mykiss) are stocked by the Washington Department of Fish and Wildlife. Additionally, Wetlands & Wildlife, Inc. identified a bald eagle nest approximately 865 feet from the project site. No impacts to the nest or any other protected areas are proposed. The lake, wetland, and associated buffers provide movement corridors which become increasingly important as pressure from human development expands. In addition to the ecological functions mentioned above, regulated Critical Areas and Shorelines of the State in western Washington also often provide aesthetic value, recreational opportunities, and educational tools. PROJECT'S IMPACT DETERMINATION RELATED TO CRITICAL AREAS It is the professional opinion of Wetlands & Wildlife, Inc. that the project has been specifically designed to minimize impacts to Critical Areas and Shorelines of the State in accordance with professional ecological industry standards and current Everett Municipal Code requirements. The proposed expansions / additions to the existing single-family residence have been specifically designed to be in accordance with the maximum total expansion amount of 1,000 square feet as allowed per EMC 19.37.050.A.k. The proposed additions have also been specifically designed to be no closer to the on-site Critical Areas /Shoreline than the existing development. Further, the proposed expansions/additions will not impact any native vegetation, and the proposed expansions will be constructed on top of existing Wetlands& Wildlife, Inc.
