   (A)   Number, separation and width.
      (1)   The number, location and width of private access drives or roads onto public roads may be controlled and limited by the City Council in the interests of public safety and efficient traffic flow.
      (2)   The minimum separation between private driveways along a public street shall be:
         (a)   Local or collector street: two times the required side yard setback for a driveway;

         (c)   U-shaped driveways, any street: 50 feet between the inside edges of the driveway surface.
      (3)   The minimum distance between the point that any private driveway meets a public street and the nearest intersection of two public street curb lines shall be 60 feet.
      (4)   The maximum width for any portion of a driveway at the property line shall be 24 feet for a residential driveway; a commercial, industrial or institutional driveway may be 28 feet if two lanes and 36 feet if three lanes.

Generally, this means that a fire truck must be able to park within working distance of a water source and still be within 150 feet of any portion of the exterior wall of a building as measured by the length of the attack hose. The all-weather paved access drive shall be at least 20 feet wide and capable of supporting the weight of the city fire truck.

   (C)   Driveways onto county roads. Access drives onto county roads shall require a review by the County Engineer, who may determine the appropriate location, size and design of the access drives and may limit the number of access drives in the interest of public safety and efficient traffic flow.
   (D)   Public road access required to each parcel. All lots or parcels shall have direct adequate physical access for emergency vehicles along the frontage of the lot or parcel from either an existing dedicated public roadway, or a private roadway or access drive approved by the City Council.
   (E)   Number of housing units allowed on a private internal access road. The maximum number of dwelling units allowed to be accessed by a single private internal circulation road or driveway is 16. Private streets are allowed only for multiple-family housing developments.
   (F)   Minimum length of driveways. Any driveway terminating at a garage shall provide at least 20 feet of parking space between the garage door and a property boundary line, a sidewalk or a private access road.
