*** Cancellation of Jail Visits because of Coronavirus ***

To prevent the spread of COVID-19 into the Contra Costa County detention facilities, the Office of the Sheriff has temporarily canceled all professional, official, and social visits at the Martinez, West County, and Marsh Creek Detention Facilities. However, attorney visits will continue with access to non-contact visit rooms only. The cancellation will be reassessed as conditions change.

The Marsh Creek Detention Facility (MCDF) is one of three primary jail facilities in Contra Costa County. Generally considered a minimum security facility by comparison, the MCDF houses incarcerated individuals who have been convicted of lesser crime classifications and have already been sentenced.

The MCDF is assigned twenty employees who are charged with running the facility’s day-to-day operations. The facility houses an average incarcerated population of 70, with a maximum housing capacity of 154. Frequently referred to as “the farm” because of its rural location, the MCDF encompasses approximately 32 acres of a 162 acre parcel located at the base of Mount Diablo.

At the MCDF, individuals are afforded opportunities for various programs, such as attending school, acquiring a GED, and participating in special courses that teach new skills and job-related training, including viticulture, wood shop, agriculture, cement work, and general construction. 

The Marsh Creek Detention Facility staff and the Office of the Sheriff work in partnership with the community to provide a safe environment for those incarcerated in the facility, the staff, and the surrounding community.
