The voters of Los Angeles County created the Los Angeles County Regional Park and Open Space District (Open Space District) when they approved Proposition A in the November 3, 1992, General Election. Proposition A authorized an annual assessment on nearly all of the 2.25 million parcels of real property in the County. Proposition A funded $540 million for the acquisition, restoration or rehabilitation of real property for parks and park safety, senior recreation facilities, gang prevention, beaches, recreation, community or cultural facilities, trails, wildlife habitats, or natural lands, and maintenance and servicing of those projects.

On November 5, 1996, the County’s voters approved another Proposition A to fund an additional $319 million of parks and recreation projects and additional funds for maintenance and servicing of those projects.
