All subdivision of property that requires construction of public
improvements shall be required to have erosion and sediment control.
All control measures required under this article shall conform
to the design criteria, standards, and specifications provided in
the Manual, now in effect or as hereafter amended. All control measures
installed shall be sufficient to prevent sediment from leaving the
permit site during a five-year-frequency storm event. The County Engineer
may require additional control measures pursuant to the standards
if determined as necessary after site inspection. A copy of the erosion
control plan filed with the IEPA and a copy of the NPDES permit shall
be furnished to the County Engineer.
