City of San Leandro 14143-14273 Washington Avenue Warehouse Project 46 portal (USFWS 2022; Appendix D). Moreover, according to the San Leandro 2035 General Plan EIR, the project site does not contain habitat for species identified as a candidate, sensitive, or special- status species (City of San Leandro 2016b). Based on the developed nature of the area and surroundings and lack of native or riparian habitat located on or adjacent to the site, no federal-or state-listed endangered, threatened, rare, or otherwise sensitive flora or fauna are anticipated to be located within the project site. Existing trees on and around the parcels within the area could contain bird nests and birds that are protected under the Migratory Bird Treaty Act (MBTA) (Appendix D). Protected birds include all common songbirds, waterfowl, shorebirds, hawks, owls, eagles, ravens, crows, native doves and pigeons, swifts, martins, swallows, and others, including their body parts (feathers, plumes, etc.), nests, and eggs. The trees located on-site and in the immediate vicinity could provide suitable habitat for migratory or resident nesting birds. No signs of bat roosts were observed during the field survey; however, trees on site and many small openings in the existing structures on-site could provide roosting habitat for bats (Appendix D). The proposed project would involve removal of 10 existing trees on the project site. In addition, construction activity associated with the project may affect protected nesting birds or bats in existing trees. Therefore, mitigation measures BIO-1 and BIO-2 are required to reduce potentially significant impacts to a less-than-significant level. Mitigation Measure BIO-1 Nesting Bird Avoidance and Minimization Measures The following avoidance and minimization measures shall be implemented during project construction activities: ▪ Initial site disturbance should occur outside the general avian nesting season (February 1 through September 15), if feasible. ▪ If initial site disturbance occurs in a work area within the general avian nesting season indicated above, a qualified biologist shall conduct a pre-construction nesting bird survey no more than 14 days prior to initial disturbances in the work area. The survey shall include the entire area of disturbance area plus a 50-foot buffer (relevant to non-raptor species) and 300-foot buffer (relevant to raptors) around the site. If active nests are located, all construction work shall be conducted outside a buffer zone from the nest to be determined by the qualified biologist. The buffer should be a minimum of 50 feet for non-raptor bird species and at least 300 feet for raptor species. Larger buffers may be required and/or smaller buffers may be established depending upon the species, status of the nest, and construction activities occurring in the vicinity of the nest. The buffer area(s) shall be closed to all construction personnel and equipment until the adults and young are no longer reliant on the nest site. A qualified biologist shall confirm that breeding/nesting is completed and young have fledged the nest prior to removal of the buffer. ▪ If construction activities in a given work area cease for more than 14 days, additional surveys shall be conducted for the work area. If active nests are located, the aforementioned buffer zone measures shall be implemented. BIO-2 Roosting Bats Avoidance and Minimization Measures A qualified biologist shall survey trees, vegetation, and existing structures with features capable of supporting roosting bats (both maternity and wintering or hibernation roosts) prior to their removal or demolition. Vegetation and existing structures shall be surveyed for bat roosts or evidence of bat
