Planned development - Process
The planned development process involves at least two steps: the preliminary development plan, and the final development plan. In many cases, land will need to be subdivided in order to carry out a development plan. The subdivision process is a separate process and may run concurrently with or following the planned development process. Planned development applications may be initiated by the owners or authorized agents of any property affected. In addition to the general requirements in § 26-8, the following requirements are specific to planned development applications:

1. Preliminary development plan process. A preliminary development plan is a generalized development plan for the entire area proposed to be included within a planned development. The purpose of a preliminary development plan is to allow preliminary review of a proposed planned development before substantial technical work has been undertaken. A preliminary development plan shall include a minimum of 2.5 acres. However, as part of the review and approval process for the preliminary development plan, this minimum site size may be waived by the Board of Aldermen upon recommendation by the Planning Commission if the parcel in question has certain unique characteristics, such as, but not limited to, significant topographic change, significant trees or wooded areas, wetlands, floodplain areas, soil conditions, utility easements, or unusual shape or proportions; or, if it is determined that the use proposed is desirable or necessary in relationship to the surrounding neighborhood; or, if the Board of Aldermen should determine such waiver to be in the general public interest. Additions to previously approved preliminary development plans may be considered an amendment to that plan and do not require a minimum size.
a. Preapplication procedure. Preliminary development plan applications are subject to the requirements of § 26-8C. 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 planning staff shall promptly schedule such a conference.
b. Application and submission requirements. In addition to the requirements of § 26-8A, applications shall be made in a form acceptable by the City Clerk.
(1) Forms. The application shall be signed by the applicant and shall state name and address. An application for a Planned Development District may be filed in the office of the City Clerk, for consideration by the Planning Commission and the Board of Aldermen. Such application may be filed any entity listed in § 26-8A.3. An application together with a complete preliminary development plan, including information outlined below, shall be considered not later than the second regular monthly meeting of the Planning Commission after all required documents are filed.
(2) Fee. Fees shall be applied according to § 26-8A.2.
(3) Preliminary development plan. A preliminary development plan shall be submitted with the application for a planned development. The preliminary development plan shall contain the information as set forth below. The scale of the drawing or drawings indicating the information required below 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 inch equals 50 feet. The applicant may be required to provide, at the applicant's expense, additional clarification and/or further detail of the site plan, as deemed necessary by the Planning Commission. All drawings shall indicate a project name, the names of adjoining streets, the applicant's name, a scale, a North arrow, the date drawn, and title of submission. The plan shall provide the following information and data:
(a) Site and landscape plan. One or a series of maps shall be submitted indicating:
(i) An out-boundary survey plat and legal description of the property.
(ii) The location, size, and height of all existing and proposed structures on the site.
(iii) The location and general design (dimensions and materials) of all driveways, curb cuts, and sidewalks, including connections to building entrances.

(ix) The location and details of all retaining walls, fences (including privacy fences, etc.), and earth berms.

(xi) Provisions for both on- and off-site stormwater drainage and detention related to the proposed development.
(xii) Proposed sign locations.
(b) Site and building sections. Schematic or illustrative sections shall be drawn to a scale of one inch equals eight feet or larger, indicating both edge conditions and internal grade changes in relation to principal variations of internal building levels and site line relations to adjacent structures.
(c) Typical elevations. Typical elevations of proposed buildings shall be drawn to a scale of one inch equals eight feet or larger or at a reasonable scale.
(d) Project data.
(i) Site area (square feet and acres).
(ii) Allocation of site area by building coverage, parking, loading and driveways, and open space areas, including total open space, recreation area, landscaped areas, and others.

(ii) The order in which the phases of the project will be built.
(iii) The minimum area and the approximate location of common open space and public improvements that will be required at each stage.
(iv) 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.
(v) Placement of all temporary structures utilized during construction, i.e., construction offices, siltation control devices, etc.

e. Board of Aldermen review and action.
(1) Before acting upon any application for a planned development, the Board of Aldermen shall publish in a newspaper of general circulation within the City notice of the meeting at least 15 days, but not more than 30 days.
