Section 405.140 "PR" Planned Residential District.
[Ord. No. 303 §§1 — 2, 2-26-2001; Ord. No. 619 §5, 8-16-2010]
A.
Creation, Purpose And Intent. The Planned Residential District is a zoning classification that may be approved under certain circumstances in situations where an applicant seeks approval of:
1.
A use listed as a planned use in the "RS-1" and "MR" Districts; or
2.
An undeveloped tract of land in excess of two and one-half (2½) acres, as an alternative to development of property pursuant to the regulations of the "RS-l" Zoning District in which it is located.
This Section is intended to authorize certain new or changed uses of property as well as certain site alterations, as specified herein, if the location and circumstances are appropriate for the use or change under the standards provided in this Section. It is also the intent of this Section to increase the flexibility of development design by authorizing the Board of Aldermen to allow deviations to the underlying district regulations and to require use of this process in certain situations. Thus, the Board of Aldermen may, by ordinance adopted in the same manner as zoning districts are amended, authorize as a legislative act of rezoning the designation of a parcel or parcels as a Planned Residential District when the proposed development or use of a specific tract of land or area warrants greater flexibility, control and density than is afforded under the general regulations of the "RS-1" and "MR" Residential Zoning Districts. Uses permitted under this development option shall be limited to those uses listed as planned uses under the applicable residential zoning district as set forth in the "RS-1" or "MR" District Regulations. |
B.
Application For Development. Application for development under this Article shall be filed in accordance with the following provisions and proceedings:
1.
