(Section 5500 et seq. State Public Resources Code)
An open-space district may develop and maintain a system of public parks, playgrounds, golf courses, beaches, trails, natural areas, ecological and open space preserves, parkways, scenic drives, boulevards and other facilities for public recreation.
Three or more cities together with any parcels of city or county territory may form an open-space district. A district may include territory in more than one county but the territory must be contiguous. Each district is divided into five or seven sub-districts. The governing board is an elected board of one member from each sub-district.
