The purpose of the drilling island (DI) district is to designate single lots and discrete areas within the boundaries of final map subdivisions and mobile home parks that contain productive or potentially productive petroleum resources to allow mineral access to explore for and develop such resources and to promote the development of such resources in a manner compatible with surrounding development. Uses in the DI district are limited to oil and gas exploration and development, production, storage, transmission, and treatment, and any accessory or ancillary equipment, structure, or facilities thereto and compatible open space and passive recreational uses.
