In 2003 the Mission Boulevard Joint Redevelopment Project was approved as a joint project with the City of Montclair. Pursuant to the terms of the Redevelopment Plan and a Cooperation and Implementation Agreement the City of Montclair has administrative responsibility for managing general redevelopment activities. The County administers the housing set-aside funds generated, focusing on housing opportunities around the unincorporated portion of the Mission Boulevard area. The total Project Area is approximately 404 acres.
