§ 94.012 GENERAL PLANNING.
   (A)   Road and street location and arrangement; paved roads.
      (1)   Paved roads or streets are required for all properties that are zoned Suburban Residential, on properties that are zoned Planned Development and that do not have a duly approved PD District Master Plan with site specific design criteria, on existed platted lot areas with lots sizes of less than 0.75 acres and on existing platted lot areas with lot widths of less than 140 feet.
      (2)   Roads or streets must conform in character, location, and arrangement to adopted plans. Governing plans include, but are not limited to, an approved area plan, county master plans, duly approved PD District Master Plans with site specific design criteria, or adopted future road or street line. The county shall be consulted for information regarding applicable plans for areas under design consideration.
      (3)   Proposed road and street arrangements must provide for the continuation of existing principal roads or streets or appropriate projections thereof if not otherwise governed by an adopted plan.
      (4)   Alleys are not to be provided where other provisions can be made for adequate and suitable service access, but are generally discouraged.
   (B)   Right-of-way and pavement width minimum standards.
      (1)   Required road and street right-of-way widths and pavement widths are established in Table 1.
      (2)   Temporary street, as approved by the Public Works Director or his or her designee.
      (3)   If the property is governed by a duly adopted PD District Master Plan with design criteria, that criteria will govern (over Table 1.)
   (C)   Access. Private driveway access to single- family development is not permitted on principal arterial or collector roads or streets, unless the roads or streets are in a rural setting making this restriction impractical.
   (D)   Cul-de-sac criteria.
      (1)   A road terminating in a cul-de-sac may only have a maximum permitted length of 600 feet, measured from the centerline of the intersecting road or street to the center of the turnaround.
      (2)   Maximum number of dwelling units allowed to be served by a cul-de-sac is 35, unless otherwise specifically approved by the county.
      (3)   Turnarounds.
         (a)   Circular turnarounds with no center island must have minimum 49 feet radius to right-of-way and must have minimum 44 feet radius paved area measured to the flowline of curb.
         (b)   Circular turnarounds with approved center island must have 56 feet radius to right-of-way and must have 47 feet radius pave area measured to the flowline of curb, with a maximum center island radius of 17 feet measured to the flowline of curb.
