The San Dieguito headwaters flow from springs on Volcan Mountain north of Julian and meander some 55 miles through conifer and oak woodlands, grasslands, and chaparral to the San Dieguito Lagoon between Del Mar and Solana Beach. It is the most intact watershed remaining in San Diego County and contains a variety of diverse ecosystems, plants, and wildlife.
The San Dieguito River Park planning area encompasses 92,000 acres along this watershed. It is a mix of open space and public and private land. We are dedicated to managing its natural resources in a sustainable manner. Currently, nearly 65% of this land is under protected public ownership.
The river valley and watershed crosses through the communities in the San Dieguito River Valley include Del Mar, Solana Beach, Rancho Santa Fe, Rancho Bernardo, Escondido, Ramona, and Julian. The River Park is owned and operated by a Joint Powers Authority, an independent agency formed by the County of San Diego and Cities of Del Mar, Escondido, Poway, San Diego, and Solana Beach to plan, acquire, improve, operate, and maintain the river valley.
We partner with the River Park, citizens, landowners, local governments, and other stakeholders to coordinate the protection of our natural resources, while respecting private property rights.
