Zoning
PD
Planned Development District
The specific purpose of the planned development district (PD) is to: Establish a procedure for the development of large parcels of land in order to reduce or eliminate the rigidity, delay, and inequity that otherwise would result from application of zoning standards and procedures designed primarily for small parcels.; 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 for flexibility, consistent with the general plan, from the rigid land use and development regulations found in base districts in order to take advantage of unique land use or site characteristics.; Encourage allocation and improvement of common open space in residential areas, and provide for maintenance of the open space at the expense of those who will directly benefit from it.; Encourage the preservation of serviceable existing structures of historic value or artistic merit by providing the opportunity to use them imaginatively for purposes other than that for which they were originally intended.; Encourage the assembly of properties that might otherwise be developed in unrelated increments to the detriment of surrounding neighborhoods.
