(a) A drainage system adequate to serve the needs of all proposed new streets and the entire subdivision will be required in new subdivisions. Where a public storm sewer main is available at the plat boundary, the subdivider shall construct a storm sewer system and connect with such storm sewer main. If such storm sewer systems are not accessible, adequate storm water drainage shall be provided by natural drainage channels with easements of adequate widths.
(b) When natural drainage channels intersect any street right-of-way, it shall be the responsibility of the subdivider to have satisfactory bridge or culverts.
(c) Pipe culverts shall be placed under all driveways where the street design provides for an open ditch.
(d) Where the street design provides for an open ditch, the ditch shall be satisfactorily constructed to drain storm water.
