A. 
Intent And Purpose.
1. 
The purpose of the Planned Development District is to provide a means of achieving greater flexibility in development of land in a manner not possible in conventional zones; to encourage a more imaginative and innovative design of projects; to promote a more desirable community environment; and to retain maximum control over both the structure and future operation of the development.
2. 
The Board of Aldermen, upon recommendation by the Planning and Zoning Commission, may, by ordinance adopted in the same manner as zoning districts are created, authorize a Planned Development 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 standard zoning districts. However, it should be noted that these planned development regulations are not intended to allow excessive densities or the development of incompatible land uses, either within the development or as the development relates to the general neighborhood. The standards contained in the following provisions must be strictly adhered to by the applicant.
The City may, upon proper application, approve a planned development for a site of at least four and one-half (4.5) acres to facilitate the use of flexible techniques of land development and site design by providing relief from zone requirements designed for conventional developments in order to obtain one (1) or more of the following objectives:
a. 
Environmental design in the development of land that is of a higher quality than is possible under the regulations otherwise applicable to the property.
b. 
Diversification in the uses permitted and variation in the relationship of uses, structures, open space and height of structures in development intended as cohesive, unified projects.
c. 
Functional and beneficial uses of open space areas.
d. 
Preservation of natural features of a development site.
e. 
Creation of a safe and desirable living environment for residential areas characterized by a unified building and site development program.
f. 
Rational and economic development in relation to public services.
g. 
Efficient and effective traffic circulation, both within and adjacent to the development site.
B. 
Relationship Of Planned Development Districts To Zoning Map.
1. 
A mapped district. The "PD" designation is not intended to be attached to existing use districts as an overlay. The "PD" designation as detailed in this Section is a separate use district and may be attached to a parcel of land as an original zoning district or it may be attached to a parcel of land through the process of Zoning Map amendment.
2. 
Plan approval required. Although the "PD" designation may be applied to parcels of land as a mapped zoning district, it is the intent of the Code that no development or redevelopment of the property encompassed by the "PD" designation take place until an acceptable development plan has been reviewed and approved in conformance with the requirements of this Section. Any pre-existing uses within the area encompassed by the "PD" designation shall have the status of non-conforming uses, as outlined in Article VII, until such time as they are included in an approved development plan.
3. 
Types of planned developments. All areas of the City subject to the "PD" designation shall be assigned one (1) of the following subclassifications which shall be considered a separate use district and subject to the specific restrictions and limitations outlined in this Section.
a. 
Planned Development — Residential (PD-R): Planned developments involving residential uses only.
b. 
Planned Development — Commercial (PD-C): Planned developments involving commercials uses only.
These subclassifications may be designated by the City at the time of the original zoning of the parcel in question, or the City may make the designation at the time of development plan application. In the instance of a request for Zoning Map amendment, the applicant may request a specific subclassification; however, it shall be at the discretion of the City, in light of the recommendations of the City's Comprehensive Plan, as well as the surrounding neighborhood to grant the requested subclassification or require a more restrictive one.
C. 
Procedures For Planned Development Approval.
1. 
Pre-application procedure. No more than six (6) months prior to filing any application for planned development approval the prospective applicant shall request a pre-application conference with the City's Building Official. Such request shall include a brief and general narrative description of the nature, location and extent of the proposed planned development; and a list of any professional consultants advising the prospective applicant with respect to the proposed planned development. Upon receipt of such request the City's Building Official shall promptly schedule such a conference.
2. 
Preliminary development plan. A preliminary development plan shall be submitted to the Planning and Zoning Commission with the application for a planned development. A final development plan, including the requirements of a preliminary plan, may be submitted as a single application when the development will be constructed as a single phase.

(9) 
The definition and location of all refuse collection facilities including screening to be provided; and
(10)

The scale of the drawing or drawings indicating the above shall be reasonably related to the site size and the complexity of the proposed development, and the scale shall in no event be smaller than one (1) inch equals fifty (50) feet. All drawings shall likewise indicate a project name, the names of adjoining streets, the applicant's name, a scale, or north arrow, and the date drawn.
The applicant may be required to provide, at applicant's expense, additional clarification and/or further detail of the preliminary plan, as deemed necessary by the Planning and Zoning Commission.
b.

The approximate date when construction of the project can be expected to begin;
(2) 
The order in which the phases of the project will be built; and
(3) 
The minimum area and the approximate location of common open space and public improvements that will be required at each stage.
(4) 
If any stage or unit as proposed contains a share of open space or other public or private recreation or service facility less than that which its size, number of units or density would otherwise require, a statement shall be submitted setting forth what bond, credit, escrow or other assurance the applicant proposes in order to ensure that the difference between that which would otherwise be required and that which the applicant proposes to provide in the instant stage or unit is ultimately provided.

Inadequate or unsafe access to the planned development;

Traffic volumes exceeding the anticipated capacity of the proposed major street network in the vicinity;
3. 
An undue burden on public parks, recreation areas, schools, fire and police protection, and other public facilities which serve or are proposed to serve the planned development;

Period Of Validity. The period of validity of approval of a final development plan is as follows:

2. 
The Board of Aldermen may grant extensions not exceeding six (6) months each upon written request of the original applicant if the application submitted is substantially the same as the initially approved application.

Should a request for extension of an approved final development plan contain substantial changes, as determined by the Board of Aldermen, the Board of Aldermen shall require the applicant to refile his/her application subject to the requirements of this Section as if it were an entirely new application.
