8-12-9: SOIL EROSION AND SEDIMENTATION CONTROL:
   A.   Purpose: The purpose of this Section is to diminish threats to public health and safety, reduce property damage and prevent the despoliation of the environment by regulating and controlling the design, construction, use and maintenance of developments and other activities which disturb or break the topsoil or otherwise result in the movement of earth on land situated in the Village.
   B.   Application of Provisions: Soil erosion and sedimentation control measures meeting the criteria and requirements established herein are required for the following:
      1.   All subdivisions and/or developments having an area of one acre or more.
      2.   Any lot or area regardless of size if deemed necessary by the Director of Engineering and Community Development in situations where property damage or despoliation develops or is likely to occur.
   C.   Specifications: All design and construction shall be done in accordance with the latest edition of the standards contained in the "Procedures and Standards for Urban Soil Erosion and Sedimentation Control" prepared by the Northeastern Illinois Soil Erosion and Sedimentation Control Steering Committee.
   D.   Design and Operation Standards and Requirements: The following rules shall govern the design and construction of land improvements with respect to soil erosion and sedimentation control:
      1.   Soil erosion and sedimentation control measures shall be provided to prevent the transportation of sediment from the site by a storm event of ten (10) year frequency or less.
      2.   Prior to the commencement of stripping or grading operations, sediment basins, debris basins, desilting basins or silt trays or other appropriate control measures shall be installed and maintained at points of storm water outflow from the site.
      3.   The smallest practical area of land shall be exposed at any given time during development.
      4.   Temporary vegetation or, where appropriate, mulching or other nonviable cover shall be used to protect areas exposed during development.
      5.   Permanent, final plant covering or structures shall be installed no later than sixty (60) days after completion of final grading of any part of the site, unless otherwise approved by the Director of Engineering and Community Development.
   E.   Submittal Requirements: Accompanying the final engineering plans of the subdivision, there shall be furnished the following information and data, in addition to that required by Section 8-12B-1-2 of this Chapter:
      1.   Topographic map, drawn at no greater than two foot (2') contour intervals, portraying clearly the drainage pattern of the area and showing the location of existing structures, utilities, bodies of water, drainage facilities, vegetative cover, paved areas and other significant natural or man-made features on the site and adjacent land within approximately one hundred feet (100') of the site boundaries.
      2.   Development plan showing areas of excavation, grading and filling; proposed contours, finished grades, provisions for storm drainage; and areas to be paved, covered, sodded or seeded, vegetatively stabilized or left undisturbed.
      3.   An erosion and sedimentation control plan indicating:
         a.   Erosion and sedimentation control measures to be employed throughout all phases of construction and after completion of development of the site.
         b.   Types of sod or seeding mixture and rate, expected dates of sodding or seeding, ground preparation, type and rate of fertilizer application and kind and qualify of mulching for both temporary and permanent vegetative control measures.
         c.   Appropriate calculations used in sizing and determining the scope of the plan.
         d.   Provisions for maintenance of control facilities.
         e.   Identification of the person(s) or entity which will have legal responsibility for maintenance of erosion control structures and measures after construction of the development is completed.
      4.   Schedule of site development operations including stripping and clearing, rough grading, installation of public improvements, building construction, final grading and landscaping. The schedule shall identify the expected date or dates of commencement of clearing, installation of temporary sediment control measures, installation of storm water drainage facilities, street paving, parking lot paving and planting of permanent vegetative cover. The schedule shall indicate the estimated duration of exposure of cleared areas.
      5.   The name, if known at the time of submittal, of the contractor(s) responsible for the installation of the control measures.
   F.   Maintenance: Persons carrying out the control measures under this Section and all subsequent owners of property where such measures have been taken shall maintain all permanent erosion control measures, structures, plantings and other protective devices.
   G.   Inspections: Director of Engineering and Community Development or his representative shall make inspections of the site while construction of the development is in progress. Where it is found by inspection that conditions are not substantially as stated or shown in the approved development plan, erosion and sedimentation control plan and schedule of site development operations, the Director of Engineering and Community Development may stop further work until deficient conditions are corrected.
   H.   Nonliability of the Village: This Section shall not create liability on the part of the Village nor any officer or employee thereof for any condition or damage which may result from reliance on this Section or on any administrative decision lawfully made hereunder.
