City of Pleasanton—Hidden Canyon Residences and Preserve Draft EIR Biological Resources FirstCarbon Solutions 3.3-27 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480016/EIR/3 - Draft EIR/21480016 Sec03-03 Bio Resources.docx and the proposed in-perpetuity preservation of 104.6 acres of habitat on the site outside of the grading envelope, should badgers occur on the site during project ground-disturbing activities, these activities could result in harm or mortality to individual badgers, and this would be a potentially significant impact. However, with the avoidance, minimization, and compensation measures provided in MM BIO-1e, impacts to badgers would be reduced to a less than significant level under CEQA. Crotch’s Bumble Bee There is a possibility the Crotch’s bumble bee occurs on the project site. If the species occurs on-site and there is a nest underground, project-related demolition, excavation, and grading activities could result in loss of individuals. Loss of underground nests or individual bees may be considered a significant impact to Crotch’s bumble bee. Accordingly, the proposed project may have a potentially significant impact. The preferred approach is to avoid and minimize impacts to them. However, if avoidance and minimization is not feasible, then the proposed project would need to compensate for the loss of habitat either on or off-site. This would likely also necessitate the need for the proposed project to obtain an Incidental Take Permit from CDFW. Therefore, the project applicant should conduct pre-activity surveys for the Crotch’s bumble bee prior to ground disturbance. Harm or mortality to individual Crotch would be considered a significant impact. However, with implementation of MM BIO-1f, which requires pre-activity surveys and avoidance, minimization, and compensatory measures, impacts would be reduced to less than significant under CEQA. San Francisco Dusky-footed Woodrats The riparian woodlands provide potentially suitable habitat for this species. However, no woodrat nests were observed during the site visit. Should woodrats occur on the project site during project ground-disturbing activities, these activities could result in harm or mortality to individual woodrats, and this would be a potentially significant impact. MM BIO-1g which requires avoidance, minimization, and compensation measures would reduce impacts to San Francisco dusky-footed woodrats to a less than significant level under CEQA. Ringtails Suitable habitat is restricted to the riparian woodlands on-site. The ringtail could occur within the riparian corridor habitat of the project site. Should ringtails occur on the site during project ground- disturbing activities, these activities could result in harm or mortality to individual ringtails. Therefore, there is a small chance site development may result in direct mortality or injury to any ringtail individuals adjacent to the riparian habitat. Direct mortality or injury to an individual ringtail would be considered a significant impact under CEQA. However, measures described in MM BIO-1h would be implemented that would avoid impacts to individual ringtails and therefore reduce impacts to a less than significant level under CEQA. Burrowing Owl The project site does contain some suitable habitat to support this species in the form of California annual grassland. No burrowing owls have ever been documented on-site during numerous surveys since 2014. The closest sightings are about 2.7 miles east of the site in the Dublin region east of Doughtery Road and about 2.5 miles south of the site along Pleasanton Ridge. No burrowing owls
