A District "B-T" may be established on a tract of land in single ownership or under unified control; provided, that a preliminary development plan for a planned trailer court district has been prepared, submitted and approved in compliance with the regulations and requirements of this Article.

Application shall be made to the Board of Aldermen for the rezoning of property for a planned trailer court district, and it shall thereupon be referred to the Zoning Commission, hereinafter referred to as the Commission for its recommendations.

The net area of land to be included in a District "B-T", and so designated, shall be at least one acre in size. The term "net area", as used herein, shall not include any area within dedicated highways, streets, alleys or other public ways or public property.

The location of any District "B-T" shall be on property which has an acceptable relationship to major thoroughfares, and the Commission must satisfy itself as to the adequacy of the thoroughfares to carry the additional traffic generated by the development.

The plan for the proposed development must present a unified and organized arrangement of trailer spaces and service facilities, which shall have a fundamental relationship to the properties comprising the planned development and shall not adversely affect the uses of property immediately adjacent to the proposed development.

The requirements and regulations herein prescribed, pertaining to height, open space, setbacks and parking, may be adjusted or modified by the Board of Adjustment after recommendation of the Commission before a District "B-T" is established, so that the property in question may be developed in a reasonable manner and, at the same time, will not be detrimental to the public welfare and interests of the City, but in keeping with the general intent and spirit of this Article.

The Commission shall have power to make and adopt such rules and regulations as are necessary and proper to effectuate the purposes of this Section.

The applicant for a planned trailer court district shall prepare and submit a preliminary development plan to the Commission for its inspection and review, upon which plan the Commission shall hold a public hearing. This preliminary plan of the property to be zoned as District "B-T", drawn to scale, shall show the boundaries of the property to be zoned, the existing topography, with contour intervals no greater than five (5) feet, unless waived by the Commission, and the proposed size, location and arrangement of trailer spaces, open spaces, parking areas, service buildings and other structures or areas to be included, entrances and exits, driveways and their relationship to existing and proposed streets, alleys and other public ways or public property, and any additional information required by the Commission. The preliminary plan shall also show the development of adjacent properties within two hundred (200) feet, including the location and type of buildings and structures thereon. If the planned trailer court district is proposed in an unplatted area, the preliminary plan shall be accompanied by a plat, giving the full legal description of the boundaries of the property to be included in the area to be zoned as a planned trailer court district. It shall also be accompanied by a plan, drawn to scale, of the general arrangement of streets within the remainder of such unplatted area, which plan need not extend more than one thousand (1,000) feet from the boundaries of the area to be zoned as a planned trailer court district.

The applicant shall indicate on the preliminary plan, if the development is to be accomplished in stages, the order in which such stages shall be developed.

The preliminary plan shall also show the location of all sewer, water main, electrical and gas utilities, which shall be provided in accordance with the applicable laws and ordinances of the City.

If the preliminary plan is found to comply with the intent of the requirements and regulations set forth in this Section, the Commission shall, upon approval of the preliminary plan, prepare and submit to the Board of Aldermen a request for an amendment to this Article, which amendment is to provide for and establish a "B-T" District for the land covered by the preliminary plan.

Upon approval of the zoning change by amendment, the applicant shall submit a final development plan to the Commission, for its review and recommendation. The final development plan may be submitted separately for the first and each successive stage of development.

It shall be the responsibility of the Commission to determine that each stage, or all, of the final development plan conforms to the intent of the preliminary plan on which the zoning change was made. The Commission, having reviewed the final development plan for any or all stages of the development and finding that it conforms with the intent of the preliminary plan, shall recommend its approval to the Board of Aldermen. If the final development plan fails to conform to the intent of the preliminary plan submitted in support of the rezoning, such final development plan may be submitted to the Commission as an amended preliminary plan upon which the Commission shall hold the public hearing. The procedure shall be the same as for the original preliminary plan.

No building permit shall be issued for any development in a planned trailer court district until the Board of Aldermen shall have approved the final development plan covering at least the first stage of development, and until the developer has deposited with the City Clerk a bond in form satisfactory to the Board of Aldermen to insure that the utilities, streets, curbs and gutters shall be constructed at the expense of the developer within the planned area within a time to be designated by the Board of Aldermen.

A final development plan, prepared for each succeeding stage, shall also be reviewed by the Commission and when approved by the Board of Aldermen as provided for above, shall be filed in the office of the City Clerk.

The applicant for a planned trailer court district shall prepare and submit a schedule of development in one or more stages, which development shall begin within a period of one year following the approval of a final development plan or any stage thereof by the Board of Aldermen. Failure to begin construction as scheduled shall void the plan, as approved, unless a request for extension of time is made by the applicant to the Board of Adjustment and approved by the Board. If for any reason the plan is abandoned, or if the development is terminated after the completion of any stage, and there is ample evidence that further development is not contemplated, the ordinance establishing such District "B-T" may be rescinded by the City and the zoning of the entire tract, or the portion which is undeveloped as a District "B-T", may be changed to a suitable classification.

After the final development plan has been approved and the zoning change made, and when in the course of carrying out this plan, adjustments or rearrangements of trailer spaces, parking areas, service buildings or other structures, entrances, heights, setbacks or other open spaces are requested by the applicant, and such requests conform to the standards established by the approved final development plan, for the area to be covered by such trailer spaces, service buildings or other structures, parking spaces, entrances, heights, setbacks or other requirements, such adjustments may be approved by the Board of Adjustment upon application and after receiving the recommendations of the Commission.

In District "B-T", no building, structure, land or premises shall be used, and no building or structure shall be erected, constructed, reconstructed or altered, except in conformance with the final development plan and except for the following uses:

In a District "B-T", the height of buildings and the minimum dimensions of trailer spaces, parking areas and open spaces shall be as follows:
