Joint Use Program

The County Board of Supervisors formally approved the County's Joint Use Program policy on August 12, 2003, whereby the public may propose various projects (e.g. landscaping and beautification projects, etc.) on county-owned property. Once a citizen or citizen group submits an application for a joint use project on County-owned property to the Application & Permit Center, the application is forwarded to Real Estate for review. Real Estate then determines who owns the property (Contra Costa County, Contra Costa County Flood Control and Water Conservation District, or State Route 4 Bypass Authority) and directs the application to that entity for further review.

Appropriate notification is given to the parties involved on whether the permit is accepted or denied.
