(A) Scope of requirements. Any development in Williamstown Township shall comply with the Standards and Specifications for Soil Erosion and Sediment Control, as adopted by the Ingham County Soil Conservation District, as well as the standards set forth in this section. All site plans, shall include sufficient information to demonstrate compliance with the soil erosion and sediment control standards of the Ingham County Soil Conservation District. The applicant shall bear the full responsibility for the installation and construction of all such required erosion control measures.
(B) Information requirements. The following information shall be submitted to the township on or with the site plan for the entire tract of land, whether or not the tract will be developed in stages:
(1) A boundary line survey of the site on which the work is to be performed;
(2) General topographic and soil conditions of the site;
(3) Location and description of existing and proposed development;
(4) Plans and specifications for proposed soil erosion and sedimentation control measures to be implemented, based on standards and specifications of the Ingham County Soil Conservation District; and
(5) A schedule indicating the anticipated starting and completion dates of development.
(C) Design standards. In addition to the Standards and Specifications for Soil Erosion and Sedimentation Control, promulgated by the Ingham County Soil Conservation District, the following design standards shall be used to provide effective control of soil erosion and sedimentation.
(1) The development plan shall complement the topography and soils on the site so as to minimize erosion potential.
(2) Permanent vegetation and improvements such as streets, storm sewers or other features of the development, capable of carrying storm run-off in a safe manner, shall be scheduled for installation prior to removing the vegetative cover from an area, if feasible.
(3) Where feasible, natural vegetation shall be retained where it aids in soil erosion and sedimentation control.
(4) The smallest practical area of land shall be exposed at any one time during development, for the shortest practical period of time.
(5) Soils exposed during construction shall be protected with temporary vegetation, mulching or other protection.
(6) Sediment basins (debris basins, desilting basins or silt traps) shall be installed and maintained to remove sediment from run-off waters from land undergoing development.
(7) Provisions shall be made to accommodate the increasing run-off caused by changed soil and surface conditions during and after development.
(8) Permanent vegetation and soil erosion control devices shall be installed as soon as practical during development.
(D) Maintenance of soil erosion and sedimentation control. Individuals or developers carrying out soil erosion and sediment control measures under this chapter, and all subsequent owners of property on which the measures have been installed, shall adequately maintain all permanent erosion control measures, devices and plantings in effective working condition.
