Planned Development Zone
The PD zone is applied to large parcels of land in order to reduce or eliminate the rigidity, delays, and conflicts that otherwise would result from application of zoning standards and procedures designed primarily for small parcels, and to: Ensure orderly and thorough planning and review procedures that will result in quality urban design; Encourage variety and avoid monotony in large developments by allowing greater freedom in selecting the means to provide access, light, open space, and amenity; Provide a mechanism whereby the City may authorize desirable developments consistent with the General Plan without inviting speculative rezoning applications, which, if granted, often could deprive other owners of development opportunities without resulting in construction of the proposed facilities; Encourage allocation and improvement of common open space in residential areas, and provide for open space maintenance at the expense of those who will directly benefit from it; and Encourage the assembly of properties that might otherwise be developed in unrelated increments to the detriment of surrounding neighborhoods. Building intensity may be up to the maximum required by the General Plan land use classification applicable to the site. The PD zone is consistent with and implements all land use classifications of the General Plan.
