§ 152.093 DESIGN STANDARDS.
   (A)   General. The following design standards for streets are hereby required. Street classifications may be indicated in the Comprehensive Plan, Thoroughfare Plan, or on the Official Map; otherwise, they shall be determined by the Commission.
   (B)   Street surfacing and improvements. After sewer and water utilities have been installed by the developer, the applicant shall construct curbs and gutters and shall surface or cause the roadways to be surfaced to the widths prescribed in these regulations. Pavement type and make shall be as determined by the jurisdictional engineer.
      (1)   Adequate provisions shall be made for culverts, drains, and bridges.
      (2)   All street pavement, shoulders, drainage improvements and structures, curbs, turnarounds, and sidewalks (if applicable) shall conform to all construction standards and specifications adopted by the Commission, engineer, or the jurisdiction and shall be incorporated into the construction plans required to be submitted by the developer for plat approval.
   (C)   Excess right-of-way. Right-of-way widths in excess of the standards designed in these regulations shall be required whenever, due to topography, additional width is necessary to provide for adequate and stable earth slopes.
   (D)   Railroads and limited access highways. Railroad rights-of-way and limited access highways where so located as to affect the subdivision of adjoining lands shall be treated as follows:
      (1)   In residential districts a buffer strip at least 25 feet in depth in addition to the normal depth of the lot required in the district shall be provided adjacent to the railroad right-of-way or limited access highway. This strip shall be part of the platted lots and shall be designated on the plat: “This strip is reserved for screening. The placement of structures hereon other than earth berms, walls, fences, and other landscape screening devices approved by the Commission is prohibited.”
      (2)   In districts zoned for business, commercial, or industrial uses, the nearest street extending parallel or approximately parallel to a railroad shall, wherever practical, be at a sufficient distance therefrom to ensure a suitable depth for commercial or industrial sites.
      (3)   Streets parallel to railroads when intersecting a street which crosses the railroad at grade shall, to the extent practicable, be at a distance of at least 150 feet from the railroad right-of-way. Such distance shall be determined with due consideration of the minimum distance required for future separation of grades by means of appropriate approach gradients.
