The park/open space district indicates areas of permanent open spaces, biological resource protection, parks and/or areas precluded from major development because of land constraints or habitat preservation. The use regulations, development standards, and criteria are intended to provide low intensity development and encourage recreational activities and the preservation and management of natural resources. Recreational uses such as golf courses with customary support facilities are considered appropriate for these areas. Agricultural uses and sand extraction operations may, under special conditions, be allowed.
The following objectives have been formulated for the park/open space district for the implementation of the General Plan goals and objectives:
A. 
Promote a balanced mix of open space uses with development throughout the City in order to provide the enhancement of visual resources, avoidance of hazards, and conservation of resources.
B. 
Preserve significant natural resources, such as mineral deposits, biological resources, watercourses, hills, canyons, and major rock outcroppings, as part of a citywide open space system.
C. 
Maintain floodways as open space in order to reduce flood hazards, and to preserve the aesthetic quality along water corridors.
D. 
Encourage the preservation of significant historical and archaeological sites in the City.
E. 
Preserve open space to adequately protect the public from fires, flooding and landslides.
F. 
Provide adequate recreational acreage and facilities in all areas of the City.
G. 
Encourage private recreational uses which exhibit large amounts of open space.
