California Code, Public Resources Code - PRC § 32514

The conservancy shall coordinate the activities of state and local agencies and private entities interested in the San Joaquin River and its resources. State and local agencies shall retain title to any land owned within the boundaries of the parkway. Local agencies may enter into an agreement to transfer responsibility for the management of the land to the conservancy. Where there is no state or local public agency with operating and management responsibility, the conservancy shall exercise that responsibility. All zoning or land use regulations shall remain the exclusive authority of the member agencies.
