Napa County Jail Environmental Impact Report (EIR)


The County Jail Project includes acquiring property and constructing a new jail on approximately 15 to 20 acres in unincorporated Napa County. The new jail would be designed with an initial capacity of 366 beds, but would include core support facilities designed to accommodate expansion up to 526 beds in the event the County needs to add bed capacity at some point in the future. Ancillary facilities would include a storage and maintenance unit, administrative offices, food services, laundry, medical and mental health units, programming rooms, visiting areas, and inmate intake and release. Additionally, a staff-secure facility would be constructed to house 50 to 100 additional inmates, and would serve as a transitional step for inmates moving back to the community. The existing jail, located in downtown Napa, would remain in use as a day-holding facility for pre-trial inmates with Court appointments, and would also continue to accommodate County offices and meeting space.

A Final Environmental Impact Report (FEIR) for the County Jail Project has been prepared in accordance with the California Environmental Quality Act (CEQA).
