§ 154.21  PRELIMINARY PLAN REQUIREMENTS; EXHIBITS AND SUPPORTING DOCUMENTS.
   (A)   Conventional subdivision developments. When a proposed land development encompasses all of a tract, or a portion of a tract later to be subdivided in its entirety, a preliminary plan and supporting documents of the entire tract shall be prepared and submitted for approval. The plan shall delineate the necessary characteristics of the tract, both existing and proposed, in conformance with the requirements specified in this section, and shall be considered to be a specific guide for the development of the affected area. The plan and supporting documents shall become operative upon approval by the Council.
   (B)   Plan drawing exhibit(s). The preliminary plan drawing shall show all necessary physical locations, identifications, elevations, and general dimensions of all applicable existing and proposed on-site and contiguous off-site physical features identified herein. It shall be the responsibility of the Applicant to fully comply with these requirements and to so certify in writing. Where the complexity of existing and proposed information, required to be shown on the plan, as outlined in this division (B), could or would cause confusion in the proper evaluation thereof by the city, the plan data may be shown on two separate drawings at the same scale. Drawing No. 1 shall show the information required in divisions (B)(1), (B)(2), and (B)(3) below, and Drawing No. 2 shall show that information required in divisions (B)(1), (B)(2)(i), and (B)(4) below.

   (C)   Supporting documents and certificates. The plan drawing exhibit(s) shall, where applicable and herein required, be accompanied by the following described supporting documents and certificates approved as to form by the City Attorney, to aid in assisting the Council in properly evaluating the nature and character of the proposed subdivision.
      (1)   Required at the time of filing the preliminary plan.
         (a)   Completed and signed preliminary plan application and certificate of compliance with regulations on the appropriate form furnished by the city, which shall attest that the owner/subdivider/applicant has, to the best of his or her knowledge, thoroughly familiarized himself or herself with the requirements prescribed in these subdivision regulations, has furnished to the city with all applicable and complete information with respect to the plan, plan drawing(s), and supporting documents, and has otherwise complied with all applicable requirements, regulations, and ordinances of the city relative thereto;

         (c)   Preliminary eight and one-half inches by 11 inches draft reflecting significant items and features being considered by the subdivider for incorporation into private deed restrictions (restrictive/protective covenants) affecting the land being subdivided. It is not the intent of this requirement that the information be prepared in proper legal form for preliminary plan review, but merely to indicate the general nature and type of covenants being considered by the subdivider as an aid to the Council in its review and evaluation of the nature and character of the subdivision. The information should give particular attention and emphasis to, but not necessarily conclusive of, the following considerations, where applicable:
            1.   Minimum gross square feet of the living area defined as the dimensions measured from interior wall to interior wall of each type (i.e., single-family detached, apartment, and the like) of the smallest dwelling unit proposed or allowed (exclusive of garages and carports);
            2.   Type(s) of exterior building materials, and minimum allowable percentages thereof, which are to enclose the sidewalls and roofs of residential and nonresidential buildings;
            3.   Prohibition regarding the conduct of any business/commercial activities within or on any residential lot or premises, other than as permitted under home occupation uses; and
            4.   Buildings and premises on each and every type lot to be kept and maintained in a safe, healthful, and proper aesthetic manner free of junk, litter, debris, grass, and weeds over one foot in height, and any other visual, audible, or related adverse environmental impacts or nuisances.
         (d)   All applicable filing fees shall be submitted to the City Secretary at the time of filing the preliminary plan.
      (2)   Optional Council requirements. The Council may, in a majority opinion, determine that the carrying out of the development proposed by the Applicant's plan could or would have an adverse impact on the existing or proposed physical environment embraced by the subdivision, require the subdivider/applicant to prepare an environmental assessment in accordance with the policies and provisions of the National Environmental Policy Act of 1969 (Pub. L. No. 91-910), being 42 U.S.C. §§ 4321 et seq., and as hereafter may be amended. The Council may require the assessment be prepared any time prior to or during the Council's review of the preliminary plan, but if required, the assessment shall be placed on file and available to the Council, and general public prior to any final decision rendered on the plan.
