City of Pleasanton–Spotorno Ranch Reduced Development Project Environmental Checklist Initial Study/Consistency Checklist 80 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480021/Consistency Checklist/21480021 Spotorno Ranch Consistency Checklist ScreenCheck.docx The LOA BRA concluded that although currently no suitable habitat is present for burrowing owl and American badger, the site may become suitable if site conditions are allowed to change, e.g., through colonization by California ground squirrel (Otospermophilus beecheyi). FCS agrees with this determination. Although the site survey conducted by FCS Biologist, Robert Carroll, did not identify any burrowing owl or the presence of burrows that could be utilized by this species, Mr. Carroll did observe several smaller-sized burrows between 1 to 1.5 inches wide (too small for use by burrowing owl and/or American badger), but nevertheless demonstrate that a suitable prey base for burrowing owl and American badger is currently present on-site. On this basis, the proposed project has the potential, albeit a low potential, to support both species. Out of an abundance of caution, it is recommended that a pre-construction survey be conducted for both species prior to any ground- disturbing activities to ensure that no species have colonized the site between March 2021 and whenever construction were to commence. This survey would conform with current best practices, including recommendations provided in the East Alameda County Conservation Strategy, which provides guidance for local agency review of projects to protect focal species. The California Department of Fish and Wildlife (CDFW) recommends that burrowing owl surveys be conducted not less than 14 days before ground-distrubing activities begin. With the inclusion of the proposed refinement to MM J3, and the implementation of both MM J1 and MM J3, as modified, potential impacts to special-status species would be less than significant, consistent with the conclusions in the 1998 HVSP FEIR. Therefore, the proposed project would not result in any new or more severe impacts to special-status species beyond what was previously analyzed in the 1998 HVSP FEIR. b) Riparian Habitat and Sensitive Natural Communities Would the project: Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, and regulations or by the California Department of Fish and Wildlife or United States Fish and Wildlife Service? The 1998 HVSP FEIR determined that development within the HVSP area has the potential to impact riparian habitats. MM J6 requires consultation with theCDFW regarding any areas within their jurisdiction. While the approximately 112-acre site contains four intermittent drainages, none of them contain riparian habitat, nor are there any riparian features within the 33-acre Spotorno Flat Area. The four intermittent drainages are all located within the proposed open space area of the project site (Parcel C), and would not be impacted by proposed project construction. Furthermore, these features, which include a tributary of Sycamore Creek (205 linear feet) in the northern portion of the open space area, and three isolated intermittent drainages (totaling 692 linear feet) in the central portion of the open space area, do not contain any riparian habitat, therefore MM J6 would not apply to the proposed project. Therefore, the proposed project would not result in any new or more severe impacts to sensitive natural communities or riparian habitat beyond what was previously analyzed in the 1998 HVSP FEIR.
