(A) The following information shall be supplied in addition to the requirements in § 151.041:
(1) Statement of proposed use of lots, giving type and number of dwelling units and type of business or industry;
(2) Location and approximate dimensions of all existing buildings;
(3) A conceptual plan for commercial and industrial development showing the locations, dimensions, and approximate grade of proposed parking and loading areas, alleys, pedestrian walk-ways, streets, and the points of vehicular ingress and egress to the development; and
(4) Description of proposed covenants and restrictions;
(B) The subdivider must submit a narrative and where needed a drainage plan to indicate how the drainage plan will meet the following standards for drainage and storm water management:
(1) To the extent practicable, all development shall conform to the natural contours of the land and natural and pre-existing man-made drainage ways shall remain undisturbed.
(2) To the extent practicable, lot boundaries shall be made to coincide with natural and pre- existing man-made drainage ways within subdivisions to avoid the creation of lots that can be built upon only by altering such drainage ways.
(3) All developments shall 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:
(a) The retention results from a technique, practice or device deliberately installed as part of an approved sedimentation or storm water runoff control plan; or
(b) The retention is not substantially different in location or degree than that experienced by the development site in its predevelopment stage, unless such retention presents a danger to health or safety.
(4) All developments shall be constructed and maintained so that adjacent properties are not unreasonably burdened with surface waters as a result of such developments. More specifically:
(a) No development may be constructed or maintained so that such development unreasonably impedes the natural flow of water.
(b) No development may be constructed or maintained so that surface waters from such development are unreasonably collected and channeled onto lower adjacent properties at such locations or at such volumes as to cause substantial damage to such lower adjacent properties.
