A drainage system shall be designed and constructed by the developer or the city as required under § 1248.11(A), as required for the district in which the proposed subdivision is located, for the proper drainage of the surface water of the subdivision and each lot as follows.
(A) An enclosed storm sewer system shall be provided where a tile inlet or an outlet with a capacity to receive the discharge is available within 1,000 feet of the subdivision or where it is determined by the Commission that storm sewers shall be provided and connected to a drainage ditch or other waterway. The system shall have a capacity to serve the subdivision and drainage area of which it is a part. The system shall include pipes, culverts, manholes, catch basins, drain inlets and a connection for each lot.
(B) An open drainage system may be permitted when inlets or outlets are not available within 1,000 feet or when the size of the outlet is not adequate to receive the discharge, as determined by the Commission. The developer may be required to deed in fee, dedicate or grant an easement to the city for a drainage channel not less in width than required by a plan or standards adopted by the city or by the existing topography along the watercourse. The developer may rechannel any watercourse through his or her property in order to contain the storm drain flow within a lesser width. The developer shall be responsible for clearing the drainage way of all debris as a condition of acceptance.
(C) The drainage system shall be designed in accordance with The Uniform Standards for Sewerage Improvements as approved by the Municipal Engineers Association of Northeast Ohio, provided that said uniform standards shall be modified to require that drainage systems constructed shall be designed to withstand a minimum 100-year storm intensity. The developer shall construct and pay for all sewers required under this regulation if said sewers traverse his or her subdivision and are necessary to serve a drainage area of which they are a part. If extra-size or off-site storm sewers are required, standards for prorating costs are set forth in § 1248.11.
