No special-status wildlife species were observed within the project site during the site visit. Wildlife observed included species commonly found in urban areas, such as American crow (Corvus brachyrhynchos), house finch (Haemorhous mexicanus), black phoebe (Sayornis nigricans), and Allen’s hummingbird (Selasphorus sasin). Nesting birds The project site and adjacent developments contain numerous ornamental trees that may provide suitable nesting habitat for bird nests protected under the Migratory Bird Treaty Act (MBTA) and/or the Fish and Game Code. However, d ue to the lack of suitable foraging habitat, it is unlikely that the special-status species, white-tailed kite, would nest in the trees on-site, although it cannot be ruled out. Potential direct and indirect impacts could occur to resident and migratory nesting bird species if project construction occurs during the nesting season (generally February 1 to August 31). Construction activities can result in noise, vibrations, and increased activity levels that could render the project site temporarily unsuitable for bird nesting, resulting in the abandonment of active bird nests, and/or subject birds to risk of death or injury; therefore, birds are likely to avoid the area until such construction activities have dissipated or ceased. Relocation, in turn, could cause hunger or stress among individual birds by displacing them into adjacent territories belonging to other individuals. No action is necessary if no active nests are found or if construction occurs during the non-breeding season (generally September 1 through January 31). MM BIO-1 requires the project Applicant to conduct a pre-construction survey and, if active nests are identified, requires the Applicant to implement further avoidance and minimization measures. Implementation of MM BIO-1 would reduce potential impacts to nesting birds to a less than significant level. Roosting bats Vacant buildings can provide suitable roosting habitat for special-status bat species including pallid bat and Yuma myotis . As noted above, the City issued a demolition permit for the existing buildings, and demolition was completed in Spring 2021. Therefore, because there are no vacant buildings on the project site or other suitable roosting habitat, the proposed project would not result in any potential impacts to roosting bats. b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, and regulations or by the California Department of Fish and Wildlife or United States Fish and Wildlife Service? No Impact. The project site is entirely developed and does not contain any riparian habitat or sensitive plant communities. Therefore, the proposed project would not have a substantial adverse effect on any riparian habitat or other sensitive natural community. No impact would occur.
