1117.16 SURFACE WATER, EROSION AND SEDIMENT CONTROL.
   Where it is necessary to make changes in the contour of any land proposed to be subdivided, developed, or changed in use by grading, excavating or the removal or destruction of the natural topsoil, trees, or other vegetative covering thereon, the same shall be accomplished only after the owner or his agent has submitted to the Village Planning Commission for approval a plan for the surface water, erosion, and sedimentation control and said plan has been approved. Said plans shall incorporate the following controls:
   (a)    All surface water shall be provided drainage ditch outlets, of a temporary nature during construction and shall be approved by the Village Engineer. No exposed area that will pond a great amount of water overnight will be permitted.
   (b)    No more than thirty percent (30%) of the total area shall be exposed at any one time during construction unless proper measures are taken to prevent erosion, siltation and sedimentation.
   (c)    No area shall be exposed any longer than necessary to recontour. Temporary vegetation and/or mulching shall be then applied for protection during the development.
   (d)    No area shall be allowed to go into the winter season without vegetative cover on critical areas as determined by the Village Engineer. Said areas shall be seeded by October 1st.
   (e)    Sediment basins (debris basins, desilting basins or silt traps) shall be installed and maintained to remove sediment from run-off waters for land undergoing development.
   (f)    Permanent final vegetation and drainage structures shall be installed as soon as grading is completed.
   (g)    The development shall be fitted to the topography and soils so as to create the least erosion potential.
   (h)    Whenever feasible, natural vegetation shall be retained and protected.
