17.15.040 Stage III – Subdivision technical review.
(A) The developer shall provide the planning and zoning director with four (4) complete sets of engineering plans and specifications prepared by a civil engineer who is currently registered in the state of Arizona. Such plans and specifications must be designed based upon the approved preliminary plat and may be prepared prior to or in conjunction with the final plat.
(B) The final plat will not be considered by the city council until all engineering plans for water, sanitary sewer, streets, grading and drainage and all other improvements have been approved by the public works director and other applicable review agencies.
(C) When applicable, for water and sewer mainline extensions, the developer must furnish Arizona Department of Environmental Quality (ADEQ) and the public works director such evidence as the ADEQ may require regarding the adequacy of the design and operation of the proposed potable water and sanitary sewerage facilities. Applications for plan review by ADEQ may only be made with written authorization of the public works director.
(D) Street light requirements as determined by Section 17.20.090.
(E) Engineering Plan and Specification Submission.
(1) Comprehensive Development Plan (CDP). In conjunction with the other engineering plans prescribed in this title, the developer must provide a CDP that illustrates the physical relationship of all the proposed utility improvements for the proposed subdivision. The intent of this plan is to cumulatively index all proposed utility improvements for easy reference, and to provide for a coordinated development effort. The developer, at his option, may choose to submit a preliminary CDP for development review committee review prior to the preparation and submittal of a final CDP and other improvement plans.
(a) At a minimum, the CDP shall depict the proposed location and separation of all public improvements and how they relate to the lots or blocks of the subdivision. The CDP shall provide approximate distances and measurements of all proposed rights-of-way; easements; one hundred (100) year floodplain limits for regulatory flows; utility placements; edge of pavement; curb, gutter, and sidewalk (if required); drainage structures; and the building footprint. The CDP shall be overlaid on a topographic map with a contour interval of not less than five (5) feet. The topographic mapping shall extend fifty (50) feet beyond the subdivision boundaries. Spot elevations for the proposed grading shall be provided at various locations to assist in determining the suitability of topography to the proposed subdivision. Finally, if the project is to be phased, the phase lines must be shown on the CDP.
(b) The criteria and requirements for streets, drainage, water, and sewer may be found in Chapters 17.20 and 17.25. (Ord. No. 2008-12, §§ 1, 2, 9-16-08. 1976 Code § 12-2-4)
