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.
A.
On-site sediment control measures shall be constructed and functional
prior to initiating clearing, grading, stripping, excavation or fill
activities on the site.
B.
Sediment control measures and temporary stormwater control measures
are to be maintained so they are operating effectively until permanent
ground surface protection and permanent stormwater control measures
are established in accordance with the Manual.
C.
Written approval shall be obtained from the County Engineer prior
to making any modification to the approved erosion and sediment control
plan.
D.
If at any time it is determined by the County Engineer that the erosion
control plan is not being followed or that proper maintenance of the
erosion control measures is not being performed, he will notify the
developer in writing of these deficiencies. If corrective action is
not taken within 10 calendar days of the date of the notification,
a stop-work order may be placed on the site until corrective action
is taken or the County Engineer may do any necessary work and make
a demand on the performance bond for reimbursement.
