City of Pleasanton—Hidden Canyon Residences and Preserve Draft EIR Biological Resources FirstCarbon Solutions 3.3-35 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480016/EIR/3 - Draft EIR/21480016 Sec03-03 Bio Resources.docx Bumble bees observed shall be photographed and a Global Positioning System (GPS) point taken. If a Crotch’s bumble bee is positively identified, general surveys shall stop and intensive surveys will begin. General Survey Timing This survey shall be conducted the season prior to the start of work (i.e., if work is expected to start in the late summer, surveys may occur that same year; if work is expected to start in winter or early spring, the surveys shall occur the year before). Avoidance Should a Crotch’s bumble bee be observed, intensive surveys to locate underground nests shall be conducted. Appropriate weather for intensive surveys is warm and sunny or sunny with some overcast with temperatures between 60° Fahrenheit (degrees Fahrenheit) and 90°. Should an underground nest be located, individuals at the nest shall be photographed to confirm species. If a confirmed underground nest of Crotch’s bumble bee is observed, the nest shall be flagged and a 25-foot buffer established around the nest. Minimization If a Crotch’s bumble bee or a Crotch’s bumble bee nest is observed, an avoidance plan would be developed and reviewed by CDFW prior to project work and/or vegetation removal or ground disturbance. Compensation If Crotch’s bumble bee exists on-site and if take avoidance is not feasible, then a mitigation plan that provides for on- or off-site compensation shall be completed. The mitigation plan shall provide for a minimum of a 1:1 replacement ratio of suitable habitat. It shall define the location and whether this mitigation is on or off- site, measures to restore and/or enhance existing habitat, management strategies to maintain the conservation value of the habitat into perpetuity, and a funding source for the ongoing management. Compensation may necessitate the need to obtain an Incidental Take Permit from CDFW under the California Endangered Species Act (CESA). If in the end, the Fish and Game Commission chooses to not list the Crotch’s bumble bee under CESA, then this would vacate the need to implement the minimization and avoidance methods above. MM BIO-1g Mitigation Measure for San Francisco Dusky-Footed Woodrats Avoidance and Minimization A qualified Biologist shall conduct a pre-construction survey for San Francisco dusky- footed woodrat nests no more than 30 days and no less than 14 days prior to the onset of construction activities in or within 50 feet of riparian habitat. This survey timing allows for the scheduling of and deconstruction of any woodrat nests which
