§ 91.057 SPECIAL DESIGN STANDARDS.
   (A)   Turn storage lanes. When congestion is or may be created on the traveled way by vehicles desiring to turn left into a development or subdivision, the creation of a left turn storage lane may be required. Left turn lanes shall be constructed as outlined in the Kentucky Transportation Cabinet’s Auxiliary Turn Lane Policy, dated July 2009. The storage lane shall be constructed without expense to the city. The applicant shall pay for a traffic study if required by the city.
   (B)   Tapers and increased radii. At some locations, entrance capacity deficiencies may result from restrictions in the alignment, profile or cross-section of the entrance rather than from interior circulation and parking problems or larger than anticipated entering traffic volumes. In these instances, improved capacity may be required by the provision of longer entrance radii or by the addition of a taper connecting the entrance radius and the edge of the traveled way.
   (C)   Limited access streets.
      (1)   The use of limited access streets on private property can be required where deemed applicable by the City Engineer, in order to minimize the number of access points to the roadway from commercial and residential developments. These limited access streets are to be indicated on the applicant’s plans and, when applicable, indicated on the record plats for the development.
      (2)   Limited access streets shall be constructed to meet city standards based on the functional street classification.
      (3)   In the layout of limited access streets, the design of the intersection of these roads with other streets is to receive particular consideration, since special traffic problems occur if small turning radii are created at these intersections. In order to minimize these turning movements and traffic interference problems, radii of sufficient length are to be approved by the city to accommodate right-turn movement from the street into the limited access street, or vice versa, as measured along the inside edge of the street and limited access street pavement.
   (D)   Divided highways.
      (1)   Median cuts. Median cuts shall be limited to 600 feet or more. The need for median cuts shall be considered upon receipt of an application for an entrance permit. Before authorizing new median cuts, consideration shall be given to aligning access points with existing median cuts through the use of redesigned parking facilities within the development or the construction of limited access streets.
      (2)   Residential entrances. Residential access shall be limited to one side of the divided highway unless aligned with an existing or proposed median cut. Such access shall be located so as to conform to appropriate spacing for the roadway, but entrances should not be any closer than two feet from a property line unless the entrance serves as a joint access between adjoining properties.
      (3)   Commercial and industrial entrances.
         (a)   Commercial and industrial entrances shall align with an existing or proposed median cut unless the entrance is deemed minor in nature whereas access may be permitted to one side of the divided highway.
         (b)   Such access shall be located so as to conform to appropriate spacing for the roadway, but entrances should not be any closer than two feet from a property line unless the entrance serves as a joint access between adjoining properties.
      (4)   Field entrances. Field entrances for use by farm equipment may be permitted by the city, but shall be limited in access to one side of the highway unless aligned with an existing or proposed median cut. Field entrances shall be considered temporary in nature and may be allowed at locations not conforming to spacing standards.
   (E)   Sight distance restrictions. A driveway, entrance or new road connection shall not be allowed at locations which will prevent a vehicle approaching at legal control speed from having a six- second visibility time to the stopping position of the driveway, entrance or new road both directions of travel based on standards established by AASHTO.
