§42-257.
Basic Control Objectives
An erosion and sedimentation control Erosion and Sedimentation Control Plan may be disapproved if the Erosion
and Sedimentation Control Plan fails to address the following control objectives:
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 activities are 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 (1) time.
D.
Control Surface Water. Surface water runoff originating upgrade of exposed areas should 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 prevent off-site
sedimentation damage.
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, an Erosion and
Sedimentation Control Plan is to include measures to control the velocity to the point of discharge so as to
minimize accelerated erosion of the site and increased sedimentation of the stream.
