City of Pleasanton—Hidden Canyon Residences and Preserve Project CEQA Findings of Fact and Statement of Overriding Considerations 20 FirstCarbon Solutions Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480016/FOF/21480016 Pleasanton Hidden Canyon Residences and Preserve Project FOF.docx Department of Fish and Wildlife [CDFW]) shall be established around the den. Because badgers are known to use multiple burrows in a breeding burrow complex, a Biological Monitor shall be present on the project site during construction activities to ensure the buffer is adequate to avoid direct impact to individuals or den abandonment. The monitor would be necessary on the project site until it is determined that any badger young are of an independent age and construction activities would not harm individual badgers. Once it has been determined that badgers have vacated the project site, burrows can be collapsed or excavated and ground disturbance can proceed. Specific Avoidance and Minimization Measures for the badger reported in Table 3-3 of the East Alameda County Conservation Strategy (EACCS) include: xx If potential dens are located within the proposed work area and cannot be avoided during construction, qualified Biologist will determine if the dens are occupied or were recently occupied using methodology coordinated with the United States Fish and Wildlife Service (USFWS) and CDFW. x If unoccupied, the qualified Biologist will collapse these dens by hand in accordance with USFWS procedures. Exclusion zones will be implemented following USFWS procedures or the latest USFWS procedures available at the time. The radius of these zones will follow current standards or will be as follows: Potential Den–50 feet; Known Den–100 feet; Natal or Pupping Den–to be determined on a case-by-case basis in coordination with USFWS and CDFW. x Pipes will be capped and trenches will contain exit ramps to avoid direct mortality while construction areas are active. Compensation The project shall permanently protect 104.6 acres as open space, which is considered more than adequate to offset any loss of badger habitat. Additionally, Focal Species Impact/Mitigation Scoring Sheets located in Appendix E of the EACCS were used as part of the assessment for suitability of mitigation lands for the badger. Standardized mitigation ratios for the badger, according to Table 3-10 in the EACCS, is 3:1 within the East Bay Hills Mitigation Area, where the project and associated conservation land are sited. MM BIO-1f Mitigation Measures for Crotch’s Bumble Bee A qualified Biologist shall conduct pre-construction surveys with methodology approved by the California Department of Fish and Wildlife (CDFW) during the three stages of Crotch’s bumble bee flight period; once a positive identification is made, no further general surveys are necessary; at that point, intensive surveys would occur. The three stages of flight periods include: 1) queen flight after emergence is February–March; 2) highest detection time for nests is April–August; 3) queens solo flight is September–October when queens find a hibernation area. Surveys will be conducted in the two flight periods prior to the start of construction with two
