§ 91.24 CULVERTS, PIPES, AND TRENCHES; STORM DRAINS; CATCH BASINS.
   (A)   Culverts, pipes, and trenches.
      (1)    The diameter of all culverts shall be determined by the county using history and run-off data available at the USDA Soil and Conservation Service. No culvert less than 18 inches in diameter will be acceptable. The length of the culvert will be determined by the height of the fill, but shall be of sufficient length to provide a minimum 22-foot wide finished roadbed.
      (2)   All concrete culverts shall conform to AASHTO M170 state requirements and only steel reinforced culvert will be acceptable.
      (3)   All pipe shall be laid in a trench in all cases where possible. Trenches shall be excavated to the required grade and to a width sufficient to allow for proper joining of the pipe and compaction of the backfill under and around the pipe. The trench bottom shall be shaped to fit the bottom of the pipe and shall have recesses shaped to fit any projected hubs or bells. All culverts shall have a minimum of 12 inches fill above the top of the culvert, excluding pavement or its base.
   (B)   Storm drains; catch basins. Catch basins shall be required to receive surface water from road side gutters or swales into piped or open ditch drains. Standard manholes and covers, inside step and gutter gratings may be required for some installations. The Public Works Director will direct the application if applicable. All curves shall be designed to pass the peak rate of run-off from at least a 25-year rain fall return frequency for a 1-hour storm.

   (B)   All soft, unstable, or unsuitable material which will not compact readily shall be removed and replaced with satisfactory material. All rocks and boulders shall be removed or broken off to a depth of not less than 8 inches below the surface of the sub-grade.
   (C)   All soil must be compacted so holes, ruts, or depressions will not form or develop. Compaction is extremely important to longevity of any road system.

   (B)   Finished road shall be crowned or elevated from the shoulder to center line.
   (C)   Pavements of hot laid asphalt (plant mix) or bituminous (triple treatment) will be acceptable. All pavements shall be a minimum of 30 feet in width.

   (E)   The surface of the mixture after compaction shall be smooth and true to establish crown and grade. Any mixture that becomes loose or broken, mixed with dirt, or in any way defective shall be removed and replaced with fresh mix which shall be immediately compacted to conform with the surrounding area. Joints between old and new pavement or between strips shall be made in such a manner as to ensure proper bond between the old and new surface.
   (F)   Bituminous surfacing shall consist of a wearing surface of applications of bituminous material and spreading of aggregate, constructed on prepared base. Emulsified asphalt shall be CRS or its equivalent and shall conform to the requirements of AASHTO.

   (I)   Immediately after the paving process is completed, shoulders shall be leveled to the pavement edge.

§ 91.29 POLICY STATEMENTS.
   (A)   The final acceptance of a road by the county does not imply the road will be widened or stabilized at any time. Types of road accepted by the county shall be:
      (1)   Triple treatment; and
      (2)   Asphalt.
   (B)   No paving will be allowed on wet surfaces or when the temperature is below 45°F or shade temperature is 40°F. Paving is not permitted during the months of December, January, and February.
   (C)   Roads in existing subdivisions which have already been paved to county standards, but which have less than the required width of right-of-way, may be accepted into the county road system, upon a further determination by County Council that special circumstances exist which justify the acceptance of the road right-of-way, and that the customary right-of- way width is not readily available for acquisition.
   (D)   The developer of a subdivision may be required to sell 50% of the parcels of a subdivided tract before the county will accept the roads therein, but this requirement may be waived by Newberry County Council for good cause shown. The purpose of this provision is to keep the county from accepting financial responsibility for new roads which may be damaged by the heavy truck traffic generally associated with the development of property and construction of new homes or businesses, and which roads may need extensive, costly repairs after being exposed to such traffic.
   (E)   Concerning roads in approved subdivisions, in the event there is any material difference between the requirements of this chapter and the chapter providing standards for road acceptance and construction in subdivisions, the provisions of the subdivision regulations shall govern. The provisions of this chapter shall govern in all other situations.
