12.10.3 Basic Control Objectives
In order for a sedimentation and erosion control plan to be approved, the following control objectives shall be met:
A. Identify Critical Areas
On-site areas which are subject to severe erosion, and off-site areas which are especially vulnerable to damage from erosion and/or sedimentation, are to be identified and receive special attention;
B. Limit Time of Exposure
All land-disturbing activity is to be planned and conducted to limit exposure to the shortest feasible time;
C. Limit Exposed Areas
All land-disturbing activity is to be planned and conducted to minimize the size of the area to be exposed at any one time;
D. Control Surface Water
Surface water runoff originating upgrade of exposed areas shall be controlled to reduce erosion and sediment loss during the period of exposure;
E. Control Sedimentation
All land-disturbing activity is to be planned and conducted so as to restrain off-site sedimentation damage; and
F. Manage Stormwater Runoff
When the increase in the velocity of stormwater runoff resulting from a land-disturbing activity is sufficient to cause accelerated erosion of the 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 increased sedimentation of the stream.
