About the Regional Park and Open Space District

Our existence originates from the efforts of state legislators who wanted to promote and protect parks and open space throughout California.

Since its inception in 1992, the Los Angeles County Regional Park and Open Space District has awarded more than $1.5 billion in grants to cities, County departments, state and local agencies and community-based organizations for projects to improve and rehabilitate our parks, recreational facilities, trails, and open space lands.

At a Glance

OUR MISSION: “To enrich and empower the communities of Los Angeles County through innovative grantmaking for parks and open space.”

We all need parks and open spaces – they have significant impacts on the everyday lives of residents and provide valuable spaces and opportunities for active and passive recreation, social engagement, and community connectivity. The Los Angeles County Regional Park and Open Space District (also commonly referred to as “RPOSD” or “the District”), was established to promote and protect the over 4,000 square miles of park and open spaces, including thousands of parks, recreation and community centers, beaches, senior centers, arboreta and botanic gardens and wildlife lands, in Los Angeles County for the enjoyment of residents and visitors.
Since its formation, the District has awarded more than $1.5 billion in grants, which have been used for hundreds of projects in the community including the development and maintenance of walking, biking and hiking trails, senior centers, tree planting programs, playground and fitness equipment as well as the restoration of our rivers, streams and beaches. Grants have helped our local governments acquire and preserve open spaces such as the Santa Monica and San Gabriel Mountains. Funding has been provided to the iconic Griffith Park, the Hollywood Bowl, the Elephants of Asia Exhibit at the LA Zoo, the Rose Garden at the South Coast Botanic Garden, and regional centers including the Castaic Regional Sports Complex Olympic Pool and the Stoneview Nature Center, along with hundreds of neighborhood parks across the 88 cities and the many unincorporated areas of Los Angeles County.

All grantees are required to acknowledge the support by utilizing our brand elements, which you can learn more about by reading the Branding Guidelines.
Our grants have and will continue to make life better in Los Angeles County by building stronger and safer neighborhoods, enriching recreational experiences, advocating equitable access to parks and open spaces, and preserving our natural spaces for this and future generations. By empowering initiatives that create, maintain, and improve our open spaces, RPOSD can help ensure that everyone in the Los Angeles County Region benefits from all that parks have to offer. This is all possible thanks to the support from the people of Los Angeles County.
