1226.06   GRADING.
   (a)   Each residential, commercial or industrial lot or parcel shall be so graded as to allow no ponding whatsoever of any surface water.
   (b)   Wherever feasible, grading shall be accomplished in such fashion that all surface water shall drain into inlets constructed within limits of the right of way.
   (c)   Where necessary, inlets and conduits draining into storm conduits shall be constructed in areas outside the limits of the right of way.
   (d)   The methods outlined in subsections (b) and (c) hereof are not to be construed as to prohibit any drainage, wherever feasible, into natural or constructed drainage channels.
   (e)   Particular attention shall be given to all grading so as to avoid any ponding on or excessive runoff to contiguous property of any surface water, both during and subsequent to the period of construction.
   (f)   In unpaved areas the minimum allowable gradient of the surface to accomplish overland flow shall be seven-tenths of one percent. The maximum allowable length of flow of surface water before entering an inlet to a conduit or a natural or constructed drainage channel shall be 500 feet.
