Whenever the topographic or surface features of a site are being altered, and it is deemed necessary by the Zoning and Planning Commission, a plan showing provisions for control of erosion and sedimentation during and after the development, construction, extraction, or other use of the site shall be prepared. Such plan shall show proposals for restoration, rehabilitation, and reclamation where necessary and shall be accompanied by documentation indicating the review and recommendation on said plan by the Portage County Soil and Water Conservation District, the Division of Lands and Soil of the Department of Natural Resources, or other competent agency or soils scientist.
Effective erosion and sediment controls shall be planned and applied according to the following principles:
(a) The smallest practical area of land should be exposed at any one time during development, construction, extraction, or other use.
(b) When land is exposed during development, use, extraction, etc., the exposure should be kept to the shortest practical period of time.
(c) Temporary vegetation and/or mulching shall be used to protect critical areas exposed during development, use, etc.
(d) Sediment basins (debris basings, desilting basins, or silt traps) shall be installed and maintained to remove sediment from run-off waters from land undergoing development, use, etc.
(e) Provisions shall be made to effectively accommodate the increased run-off caused by changed soil and surface conditions during and after development, use, etc.
(f) The permanent final vegetation and structures shall be installed as soon as practical in the development, use, restoration, rehabilitation, etc.
(g) The development, extraction or use plan shall be fitted to the topography and soils so as to create the least erosion potential.
(h) Wherever feasible, natural vegetation should be retained and protected.
