11-2-3: PRELIMINARY PLAT STAGE:
The preliminary plat stage of land and airspace subdivision includes detailed planning, submittal, review and approval of the preliminary plat. To avoid delay in processing his application, the subdivider shall provide the department with all information essential to determine the character and general acceptability of the proposed development.
   A.   Compliance With Zoning Regulations: The subdivision shall be designed to meet the specific requirements for the zoning district within which it is located. However, in the event that a zoning amendment or a zoning adjustment is necessary for conformance with district regulations, said action shall be initiated by the property owner or his authorized agent. The department shall not proceed with processing of the preliminary plat until the necessary amendment or adjustment has been obtained. Any furtherance of predevelopment activity engaged in by or in behalf of the developer while an application for zoning amendment or variance is pending shall in no instance be construed as having been undertaken in reliance of a favorable determination of such application, notwithstanding the nature of a department recommendation on the matter. In any event, any such zoning amendment or adjustment required in relation to the preliminary plat shall have been adopted prior to preliminary plat approval.
   B.   Inform Health Department Of Sewage Disposal, Water Supply And Fire Protection: As a prerequisite of preliminary plat review by the department, the subdivider shall have informed the county health department of his tentative plans and learned the general requirements for sewage disposal, water supply and fire protection as applied to his location. (1988 Code § 14-2-3)

Submission shall include fees as required by section 11-1-5 of this title. Copies of the preliminary plat shall be reproduced in the form of blueline or blackline prints on a white background. Scheduling of the case for commission hearing shall be dependent upon adequacy of data presented and completion of processing. (1988 Code § 14-2-3; amd. 2004 Code)
      2.   The submittal shall be checked by the department for completeness and assigned a case number. If incomplete as to those requirements set forth in this section, the submittal shall be rejected and the subdivider notified within five (5) days of the date the map was received.
      3.   Preliminary plats of subdivisions outside the town but within a three (3) mile radius of the town shall be submitted by the developer to the town planning and zoning department for review with fees as outlined in section 11-1-5 of this title. In addition, the joint town/county planning and zoning commission shall meet to review the plat and forward its recommendation to the county planning and zoning commission pursuant to Arizona Revised Statutes section 9-474, as amended.
   D.   Review Procedures:
      1.   On receipt of the preliminary plat, the department shall perform its review for compliance to public objectives, giving special attention to design principles and standards as set forth in chapter 3 of this title, streets and thoroughfares as related to the town street and highway plans and to neighborhood circulation, utility methods and systems, existing and proposed zoning and land use of the tract and its environs, and land required for schools, parks and other public facilities.

      3.   The reviewing offices shall transmit their recommendations to the department in writing. The department shall receive and summarize the reviewing offices' recommendations, prepare a report and present it to the commission. (1988 Code § 14-2-3; amd. 2004 Code)
   E.   Approval Of Preliminary Plat:
      1.   If the department report indicates that the requirements of this title have been met, the commission shall consider the preliminary plat at the next regular meeting but not less than thirty (30) days from the date of filing.
      2.   The commission shall consider the preliminary plat and the department recommendations, and if satisfied that all objectives have been met, the commission shall approve the preliminary plat, and the secretary shall stamp a notation of approval on two (2) copies of the plat, one being returned to the subdivider and one retained in the permanent commission file.
      3.   If the plat is generally acceptable but requires minor revision before proceeding with preparation of the final plat, the commission shall find conditional approval and note the required revisions in the minutes of the meeting and in a report to the subdivider. At the direction of the commission, the plat may be given approval, subject to the revisions, in accordance with the stated conditions and review by the department.
      4.   If the commission finds that the plat requires major revision, the plat may be continued pending revision or resubmittal for the same tract or any part thereof and shall follow the aforementioned procedures.
