Napa County Replacement Detention Facility, PW 20-100


Project Scope

In 2004, the need to replace the existing downtown Napa jail was identified and the Adult Correction Master Plan was developed with collaboration between Napa County Department of Corrections, the Probation Department, the Sheriff’s Office, the Offices of the District Attorney and Public Defender, Health and Human Services Agency, Napa County Courts, and the Napa Police Department. After community meetings and discussions, the Board of Supervisors determined that a replacement jail should be located outside of downtown Napa, and subsequently a site on Napa Vallejo Highway, near Syar Industries, was purchased to house the replacement jail and a re-entry facility.

The new Jail Facility will be designed to include eight 32-Bed Housing pods, two 24-Bed Dormitory Housing units and Medical and Mental Health Services spaces (28-Beds and 2 Isolation rooms) for a total of 332 total Beds. In addition, the facility will include all of the necessary functional spaces to operate a fully functional Jail facility.
