Therefore, potential air quality impacts would be considered less than significant. Biological Resources.The project site is located within marine aquatic habitat in the lower tidal reaches of Redwood Creek. Surrounding areas are dominated by urban industrial land uses; a large apartment complex and a levee topped with a pedestrian trail are located north of the project site across Redwood Creek. The area just south of the project site along the shore of Redwood Creek is currently an active construction site for the 1548 Maple Street private residential development. East of the project site, across Redwood Creek, is an abandoned salt pond with a breached levee that now supports a tidal lagoon and mudflats with fringing salt marsh and ruderal uplands. The project site is located within critical habitat for two federally listed fish species, North American green sturgeon (southern distinct population segment [DPS]) (Acipenser medirostris) and steelhead (central California coast DPS) (Oncorhynchus mykiss). In addition, the reach of Redwood Creek within the project site is considered essential fish habitat (EFH), under the jurisdiction of the National Oceanic and Atmospheric Administration National Marine Fisheries Service (NMFS), for coho salmon (Oncorhynchus kisutch), Chinook salmon (Oncorhynchus tshawytscha), Pacific coast ground fish, and Pacific coastal pelagic fish. The proposed project would have net benefits to biological resources in lower Redwood Creek through the daylighting of approximately 2,000 linear square feet of open water by removal of the existing floating dock. The removal of the existing floating dock would improve open water habitat for fish and harbor seals that may move through the project area during high tides and increase open water and benthic foraging habitat for waterbirds including various species of ducks, grebes, and terns. In addition, the proposed project would have net beneficial effects to critical habitat for federally listed green sturgeon and steelhead and EFH for coho and Chinook salmon, Pacific coast ground fish, and Pacific coastal pelagic fish. Although the proposed project would not entail removal of any in-water infrastructure, proposed de-construction activities would occur on the surface of Redwood Creek. Any spills, or other accidental release of materials (e.g,. debris, contaminants) into the water during deconstruction activities could affect water quality, resulting in impacts to wildlife associated with Redwood Creek. As outlined in the Project Description, the City would be required to obtain coverage under NWP No. 22 (Removal of Vessels) from the Corps, which applies to the removal of manmade obstructions to navigation, such as the existing dock. In addition, the proposed project would be required to submit a Notice of Intent (NOI) and application fee to the RWQCB and implement the Construction Conditions as required under the General Order. Based on the proposed deconstruction activities and methods, which include implementation of applicable regulatory requirements, including the Construction Conditions as outlined in Section VI. Conditions of the General Order, potential impacts to fish, foraging waterbirds, and harbor seals would be less than significant. 6.G. - Page 20 of 45 198
