ronmental Checklist 3.13. Mineral Resources Would the Project: a) Result in the loss of availability of a known ❑ © ❑ mineral resource that would be a value to the region and the residents of the state? b) Result in the loss of availability of a locally ❑ ❑ ❑ 0 important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan? Discussion a,b) Impacts to mineral resources. The Proposed Project site is situated in an area classified as MRZ-1, where no significant mineral deposits are known to exist.41 Additionally, the site does not host any mines, mineral processing plants, or oil, gas, or geothermal wells.42 San Leandro's General Plan notes that the city's primary mineral resources are volcanic rocks, such as basalt, andesite, and rhyolite. Rhyolite from the East Bay Hills has been a key material in construction and development projects for over a century. The city's only quarry, located east of the city limits on Lake Chabot Road, ceased operations in the 198Os. Operational since 1886, this quarry produced aggregate and fill material for numerous construction projects across the East Bay. While additional rock resources remain at the site, future quarrying is unlikely due to potential environmental impacts and the challenges of obtaining permits.43 Local land use plans do not recognize any locally important mineral resources at the Project site. The Proposed Project does not include any mining activities. As such, the construction or operation of the Project will not impact, destroy, or restrict access to any significant existing mineral resources. Im act Designation: No impact Cumulative Impacts on Mineral Resources Since the Project is not expected to impact mineral resources, it consequently would not contribute to any cumulative impacts in this regard. 41 California Department of Conservation, Division of Mines and Geology. 1987.
