(a) The design criteria for the drainage systems shall be based on the State of Ohio Department of Transportation Design Policy and the drainage requirements (#1 through #8) of the 1963 Portage County Subdivision Regulations, with the exception being a minimum easement width of twenty feet.
(b) These criteria shall apply to development along existing roads as well as those requiring new roads to be constructed.
(1) Road drainage system. The road storm drainage system shall serve as the local drainage system. It shall be designed to carry roadway, adjacent land, and house storm water drainage. To prevent excessive pipe sizes, storm sewers shall drain into natural waterways where possible.
(2) Off-road drainage system. The design of the off-road drainage system shall include the watershed affecting the allotment and shall be extended to a watercourse or ditch adequate to receive the storm drainage.
