Biological Resources Site Assessment Report Hana Japan Steak House Project Site, Pleasanton, California APN: 941-1710-101 Page 3 Prior to conducting the August 13, 2024 survey on the project site, M&A searched the CDFW’s Natural Diversity Database RareFind 6 Application (CNDDB)1 for occurrences of special-status plants within a three-mile radius of the project site. Drawings, photographs and written descriptions of all special-status plants known from the area were reviewed prior to or during the survey period. Table 3, attached, lists the special-status plant species known to occur within 3 miles of the project site. The only special-status plant species record found within a 3-mile radius was for the Congdon’s tarplant (Centromadia parryi congdonii). The closest record for this species is located approximately 1.3 miles from the project site and was last observed in 2009. There are no alkaline soils present onsite that would support this plant. Given the proximity to Interstate 580, Stoneridge Mall, and other nearby businesses, a significant amount of ambient noise and human presence greatly discourages wildlife use of the project site. However, the offsite oak trees that border the southwestern edge of the project site approximately 50-100 feet away provide adequate nesting substrate for urban-adapted, tree- nesting songbirds and could provide suitable nesting habitat for raptors. The trees offsite could also offer suitable roosting habitat for bats. Onsite there are small mammal burrows that could provide potential habitat for Western Burrowing Owl (Athene cunicularia hypugaea) and Crotch’s bumble bee (Bombus crotchii). Both of these species rely on rodent burrows for nesting and refugia. Therefore, to avoid impacts to Western Burrowing Owl, raptors, other nesting birds, and bumble bees, preconstruction surveys for these wildlife species should be conducted. Mitigation measures are also prescribed below should these resources be found onsite. 4.1 Nesting Birds Nesting passerine birds and raptors could be impacted by the proposed project. Nesting birds are protected under the Migratory Bird Treaty Act (50 CFR 10.13), and their eggs and young are protected under California Fish and Game Code Sections 3503, 3503.5. Any project-related impacts to these species would be considered a significant adverse impact pursuant to CEQA. Potential impacts to these species from the proposed project include disturbance to nesting birds and possibly death of adults and/or young. In the absence of survey results, it must be concluded that impacts to nesting raptors and songbirds (i.e., passerines) from the proposed project would be potentially significant pursuant to CEQA. This impact could be mitigated to a level considered less than significant. 4.1.1 APPLICABILITY TO THE PROPOSED PROJECT To avoid impacts to nesting birds, a nesting survey should be conducted within 7 days of commencing with grubbing, grading, construction work or tree removal if this work would commence between February 1st and September 1st. The nesting survey should include an examination of all trees, shrubs, and the ground onsite (for ground-nesting birds) and within 100 feet of the entire project site (i.e., within a zone of influence of nesting birds). The zone of influence includes those areas outside the project site where birds could be disturbed by earth- moving vibrations and/or other construction-related noise.
