City of Pleasanton–Spotorno Ranch Reduced Development Project Initial Study/Consistency Checklist Environmental Checklist FirstCarbon Solutions 79 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480021/Consistency Checklist/21480021 Spotorno Ranch Consistency Checklist ScreenCheck.docx a) Special-status Species Would the project: Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special- status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or United States Fish and Wildlife Service? The 1998 HVSP FEIR evaluated project impacts in relation to biological resources and found that the project could have a potentially significant impact on special-status species without mitigation. The 1998 HVSP FEIR included MM J1 and MM J3 to protect special-status species: MM J1 requires preparation of a California Tiger Salamander Protection Plan, while MM J3 requires pre-construction surveys for nesting raptors, and the implementation of protective measures, where needed. As documented herein, the project as currently proposed would have a similar level of potential impact to sensitive species. Accordingly, MM J1 and J3 would still be required. The City would also enhance the implementation of MM J3 as part of conditions of approval for the proposed project to include a pre-construction survey for burrowing owl as well as for Amercian badger, and the implementation of protective measures, if needed. This proposed refinement to MM J3 would enhance the protection of special-status species, in accordance with curent best practices. A Biological Resources Assessment (BRA) was prepared for the project site by Live Oak Associates (LOA) on June 12, 2017. LOA also conducted focused rare plant surveys on June 26, 2018, and September 11, 2018 (Appendix C). An FCS Biologist also surveyed the project site in March 2021 in order to confirm the findings of the previous LOA studies. The LOA BRA concluded that the development of the proposed project has the potential to impact the following special-status wildlife: California tiger salamander (Ambystoma californiense), burrowing owl (Athene cunicularia), grasshopper sparrow (Ammodramus savannarum), northern harrier (Circus hudsonius), American badger (Taxidea taxus), pallid bat (Antrozous pallidus), and Townsend’s big-eared bat (Corynorhinus townsendii). The 2018 LOA rare plant surveys concluded that project site did not contain any rare plant species including Congdon’s tar plants (Centromadia parryi ssp. Congdonii) and big tarplant (Blepharizonia plumose). Therefore, the development of the project site would not impact any rare plants. FCS Biologist, Robert Carroll, surveyed the project site on March 11, 2021. Mr. Carroll’s observations generally support the overall findings of the LOA BRA; however, Mr. Carroll found that the project site does not contain any structure or trees that would provide any suitable roosting habitat for bats as the site does not contain any suitable structures or trees to shelter roosting bats. The project site does not contain any trees that could provide suitable nesting habitat for special- status bird species, although suitable nesting trees can be found on adjacent properties, and therefore it is possible that special-status birds may forage on-site, including grasshopper sparrow and northern harrier.
