Sec. 22.12.010. - Purpose of chapter.¶
This chapter provides regulations for development and new land uses in the special purpose zoning districts established by section 22.06.020 (Zoning districts established).
(1) AG (agricultural) district. The AG zoning district is intended for application to areas upon annexation to the city, where low density residential uses, agricultural and compatible open space uses, and public facility and recreation uses are desired. The maximum allowed density for new single-family residential development is one dwelling per five gross acres. The AG zoning district is consistent with the agricultural land use category of the general plan.
(2) OS (open space/conservation) district. The OS zoning district is applied to areas of the city with open space resources, including scenic qualities, sensitive environmental features including wildlife habitat, and/or natural hazards. The district may also be applied to sites that have been restricted to open space by map restriction, deed (dedication, or condition, covenant and/or restriction), or by an open space easement in compliance with Government Code § 51070 et seq. and § 64499 et seq. The maximum allowed density for new residential development within this zoning district will be one dwelling unit per parcel, unless construction was previously restricted or prohibited by Los Angeles County. The OS zoning district is consistent with the open space land use category of the general plan.
(3) REC (recreation) district. The REC zoning district is applied to areas appropriate for active and passive recreational uses including golf courses, public parks, and private, primarily outdoor, recreation facilities. The REC zoning district is consistent with the golf course, park, and private recreation land use categories of the general plan.
(4) SP (specific plan) district. The SP zoning district is applied to specific subareas identified in the general plan as planning areas (PA), where site characteristics require careful and creative design to integrate proposed development with existing natural resources. The type, amount, and mixture of land uses allowed within the SP district shall be determined through the specific plan process. The SP zoning district is consistent with the planning areas and specific plan overlay land use categories of the general plan.
