Zoning
P-D
Planned Development District
This district accommodates various types of development, such as neighborhood and district shopping centers, professional and administrative offices multiple housing developments, single-family residential developments, commercial service centers, and industrial parks, or any other use or combination of uses which are appropriately a part of a planned development. This district is intended to enable and encourage flexibility in the design and development of land so as to promote its most appropriate use; to allow diversification in the relationship of various uses, structures, and space; to facilitate the adequate and economical provision of streets and utilities; to preserve the natural and scenic qualities of open space; to offer recreational opportunities convenient to residents to enhance the appearance of neighbor-hoods through the preservation of natural green spaces; and to counteract the effects of urban con-gestion and monotony. The minimum area required for the establishment of a residential Planned Development shall be three contiguous acres of land and the minimum area for an exclusively non-residential Planned Development shall be one contiguous acre of land.; Planned Development Districts are intended to accommodate a wide range of residential, commercial and industrial land uses which are mutually supportive and compatible with existing and proposed develop-ment on surrounding properties. P-D Districts shall encourage the use of flexible development standards designed to appropriately integrate a project into its natural and/or man-made setting and shall provide for a mix of land uses to serve identified community needs. In addition, P-D Districts shall orient pedestrian and bicycle facilities to encourage non-auto oriented circulation within the development. Further-more, the P-D process may be used to implement the various Specific Plans adopted by the city. Once established, the P-D District becomes, in effect, the zoning code for the area within its respective boundaries.
