Cul-de-sac streets or courts designed to serve ten (10) lots or less shall have an outside right of way diameter of at least eighty feet (80') and a curved diameter of at least seventy feet (70').
   L.   Alleys: Alleys may be required at the rear of all lots to be used for business purposes, but shall not be provided in residential blocks, except where the subdivider produces evidence satisfactory to the commission of the need for alleys.
   M.   Low Density Developments: In low density developments which meet the requirements of and are zoned agricultural A-1, a design alternative, commonly called "drainage swale" may be used instead of the "curb and gutter" now called for by the design criteria approved and established by the planning commission. Such a design alternative may be used on local and collector streets and must be of such size and construction as to meet the drainage requirements called for in the "Engineering Drainage Analysis" which accompanies the preliminary plat. The design of the "drainage swale" must be equal to or superior to that required in the design criteria approved by the planning commission. If the "drainage swale" alternative is selected by the developer, the right of way width of local streets must be increased to sixty feet (60'); however, the paving width requirement will remain at twenty seven feet (27'). The authority to use "drainage swale" is not to be construed as a lessening of the standards of this chapter, but must, if chosen, be in strict compliance with the design criteria of the planning commission. (2000 Code § 12-419)
   N.   Construction Specifications: All public streets within the corporate city limits shall be constructed as outlined in Appendix A, "General Notes And Typicals For Asphalt Streets" or Appendix B, "General Notes And Typicals For Concrete Streets" attached to the ordinance codified herein on file in the office of the city clerk.

In blocks over one thousand feet (1,000') long, the commission may require public crosswalks across the block.
   B.   Width: Residential blocks shall be wide enough to provide two (2) tiers of lots of minimum depth, except where fronting on arterials are prevented by topographical conditions or size of the property, in which case the commission may approve a single tier of lots of minimum depth.

The dimensions and area of each lot may be established at the levels necessary to fulfill the requirements of the health department.

   G.   Corner Lots: Corner lots shall be at least seventy feet (70') wide at the building line to allow for side street building lines. Building lines may be less than twenty five feet (25') when the average slope of the first fifty feet (50') of the lot is greater than twenty percent (20%).

         a.   Arterial and major street paving widths shall be in conformance with standards set forth in the master plan.
         b.   Other streets shall be paved to widths specified in section of this chapter. The subdivider shall install pavement up to thirty six feet (36') in width from back of curb to back of curb.
         c.   Street pavements shall be installed according to the city specifications as adopted by the city council.
      3.   Curbs And Gutters: Curbs and gutters shall be installed on all streets. Installations shall be in accordance with the city specifications as adopted by the city council.

         a.   Sidewalks shall have a width of four feet (4') and shall be installed on both sides of all streets for a distance of at least two thousand feet (2,000') on those streets which would provide direct access to a school site.
         b.   Sidewalks shall be constructed on both sides of collector streets and major thoroughfares and on the property line side of all frontage roads on arterials. The planning commission may exempt industrial subdivisions from sidewalk requirements.
         c.   The commission may require additional sidewalks and wider sidewalks near commercial areas, schools and other places of public assembly.

         a.   Water Supply: Where a public water supply is within five hundred feet (500') or a reasonable distance, the subdivider shall install or have installed at his own expense a system of water mains which shall be inspected and approved by the director of public works or his designee, and connect to such supply. A connection to each lot shall be installed prior to the paving of the street if possible. Where a water line capacity is required that is in excess of that needed by the subdivision for water supply and fire protection, such extra cost shall be reimbursed to the subdivider. Where a public water supply is not available, each lot in a subdivision shall be furnished with a water supply system approved by the health department. All water plans shall be approved by the city engineer.
         b.   Sanitary Sewage Disposal: Where a public sanitary sewer is within five hundred feet (500') or a reasonable distance of any point of a subdivision, the subdivider shall connect with such sewer at his own expense; except where such additional capacity is in excess of that required by the subdivision, the subdivider shall be reimbursed such extra expense, and provide a connection to each lot. Such sanitary sewage system shall be installed prior to the installation of the street pavement. Where a public sanitary sewer is not accessible, an alternate method of sewage disposal for each lot, or a community sewage disposal system, may be used when in compliance with the standards of the health department and these regulations. In the preceding subsections of this section on utility lines, the phrase, "Every subdivider shall be required to install..." shall be interpreted to mean that the subdivider shall cause the improvements referred to herein to be installed, or whenever a septic tank and absorption system or private water supply is to be provided, that the subdivider shall require, as a condition in the bill of assurance of the subdivision, that those facilities shall be installed by the builders of the improvements of the lots in accordance with this chapter. All sewer plans shall be approved by the Oklahoma state department of health and the director of public works.

      8.   Monuments: Monuments shall be of such material, size and length as may be approved by the city engineer. Monuments shall be set on all outside lines of the subdivision at angle points and points of curve. (2000 Code § 12-423; amd. Ord. 1075, 3-11-2008, eff. 4-10-2008)

12-4-24: SPECIAL EXCEPTIONS TO IMPROVEMENT REQUIREMENTS:

   A.   Waiver Of Requirements: The commission, upon the request of the subdivider, shall waive the requirements of design, but not of procedure or improvements, whenever the tract to be subdivided is of such unusual size or shape or is surrounded by such development or unusual conditions that the strict application of the requirements contained in this chapter would result in substantial hardship or inequity. Such modification may be granted upon written request of the subdivider or his engineer stating the reason or reasons for each modification, and approval of such modification shall require a four-fifths (4/5) vote of the regular membership of the council or two-thirds (2/3) vote of the regular membership of the commission.

The subdivider may be required to furnish special information in order to aid the commission in its determinations. (2000 Code § 12-424)
