(A) All developments must be provided with a drainage system that is adequate to prevent the undue retention of surface water on the development site. Surface water shall not be regarded as unduly retained if:
(1) The retention results from a technique, practice or device deliberately installed as part of an approved sedimentation or stormwater runoff control plan; or
(2) The retention is not substantially different in location or degree than that experienced by the development site in its pre-development stage, unless such retention presents a danger to health or safety.
(B) No surface water may be channeled or directed into a sanitary sewer.
(C) Whenever practicable, the drainage system of a development shall coordinate with and connect to the drainage systems or drainage ways on surrounding properties or streets.
(D) Use of drainage swales rather than curb and gutter and storm sewers in subdivisions is provided for in § 152.326. Private roads and access ways within un-subdivided developments shall utilize curb and gutter storm drains to provide adequate drainage if the grade of such roads or access ways is too steep to provide drainage in another manner or if other sufficient reasons exist to require such construction.
