Sec. 9.4.3. Objectives

  1. The objectives to be considered in planning, developing, implementing and maintaining adequate erosion and sedimentation controls and undertaking land-disturbing activities are to.
    1. Identify Critical Areas
      Identify on-site areas which are subject to erosion and off-site areas which are vulnerable to damage from erosion or sedimentation and provide special attention to these areas.
    2. Limit Time of Exposure
      Limit time of exposure of all land-disturbing activities so that such activities are planned and conducted to limit uncovered soil surfaces to the shortest feasible time.
    3. Limit Exposed Areas
      Limit exposure of all land-disturbing activities so that these activities are planned and conducted to minimize the size of the uncovered area at any 1 time.
    4. Control Surface Water
      Control surface water runoff originating upgrade from uncovered soil surfaces to reduce erosion and sediment during the period of exposure.
    5. Control Sedimentation
      Control all land-disturbing activities so that such activities are planned and undertaken to prevent off-site sedimentation damage.
    6. Manage Stormwater Runoff
      Manage stormwater runoff when the increase in the velocity of stormwater runoff resulting from a land-disturbing activity can cause accelerated erosion at the point of discharge or receiving watercourse, plans are to include measures to control the velocity at the point of discharge so as to minimize accelerated erosion of the site and sedimentation of the receiving watercourse.
    7. Control Operations in Lakes or Natural Watercourses
      Control land-disturbing activities in connection with construction in, on, over or under a lake or natural watercourse so that such activities are planned and undertaken to minimize the extent and duration of disturbance of the lake or natural watercourse. Natural watercourses should be preserved.
  2. An erosion and sedimentation control plan may be disapproved if the plan fails to address the foregoing control objectives.
  3. When deemed necessary by the approving authority, a pre-construction conference shall be held.
