AUGUSTIN BERNAL MOUNTAIN BIKE TRAIL PROJECT DRAFT INITIAL STUDY 12956 DUDEK 45 April 2022 bike use into nearby open space. Any wildlife that currently move through the area are expected to have adapted to the moderate amount of unauthorized mountain bike traffic that already occurs on the project site, and the project would not significantly change this condition. Resident wildlife that regularly move through the area while foraging and dispersing may temporarily alter their movement patterns to avoid increased noise, vibration, human activity, and artificial lighting generated by the project during the approximately 3-month construction period and potentially several weeks after. Similarly, migratory wildlife (e.g., birds and bats) may avoid using areas exposed to increased disturbance activity as stopover habitat if the project were constructed during a fall or spring migration period. Such impacts would be temporary, however, and both native and migratory wildlife are expected to resume normal movement patterns soon after project construction is completed. Therefore, impacts from the project on wildlife movement and the East Bay Hills-Diablo Range habitat linkage would be less than significant. The project would not impede the use of native wildlife nursery sites. As discussed in Section 3.4(a) above, project construction would occur during the nesting season. Trimming of tree branches and moving downed tree branches or trunks could affect active nest sites while construction-generated noise could cause indirect impacts to some nesting bird species if adults nesting within auditory range of construction perceive such disturbance as a threat and abandon eggs or recently hatched nestlings. However, implementation of the Nesting Bird AMM that is incorporated in the project design and construction methodology would ensure that such impacts are avoided and there would therefore be no impact on native bird nests. e) Would the project conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? The project would not conflict with any local policies protecting biological resources. No heritage trees protected by Chapter 17.16 of the Pleasanton Municipal Code would be removed. The project would add signage at the entrances of decommissioned trails to minimize intrusion within natural public open space, and has been designed to minimize impacts to native vegetation and wildlife habitat; decommissioned trails and temporarily disturbed areas would be restored to natural conditions. Therefore, the project would have no impact on local policies or ordinances protecting biological resources. f) Would the project conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? To date, there are no adopted Habitat Conservation Plans, Natural Community Conservation Plans, or other approved Habitat Conservation Plans that cover the project site. Therefore, the project would not conflict with an adopted Habitat Conservation Plan and there would be no impact. Mitigation Measures MM-BIO-1 Compensatory Mitigation for Loss of Special-Status Plants. If any special-status plant occurrences found during the botanical survey cannot be avoided without compromising trail integrity (e.g., if plants are in a cut-fill area required for drainage or slope stabilization),
