(A) Required, standards.
(1) Erosion and sediment control planning shall be part of the initial site planning process. In planning the development of the site, the applicant shall consider the sensitivity of existing soils to erosion and topographical features such as steep slopes, stream corridors and special management areas which must be protected to reduce the amount of erosion and sedimentation which occurs. Where appropriate, existing vegetation shall be protected from disturbance during construction by fencing or other means.
(2) Standards and specifications for erosion and sediment control measures shall be in accordance with the Illinois Urban Manual (latest edition), Illinois Department of Transportation Standard Specifications, and the village’s national pollution discharge elimination system (NPDES) permit.
(3) Erosion and sediment control plans shall be in accordance with § 153.05
(Required Submittals for Stormwater Management Permits) of this chapter and shall include the following:
(a) Detailed construction phasing plan identifying erosion and sediment control measures to be in place for each phase shall be submitted;
(b) Erosion and sediment control measures to be installed initially prior to stripping existing vegetation or mass grading shall be indicated on the plans;
(c) Permanent stabilization measures shall be indicated on the erosion and sediment control plan; and
(d) A temporary stilling/sedimentation basin should be constructed at each major inlet to a detention or retention facility. The volume of the basis should be at least 500 cubic feet per acre of impervious surface in the drainage area. Side slopes of the basins shall be no steeper than three to one (horizontal to vertical) and basin depths should be at least three feet deep to minimize re-suspension of accumulated sediment. A detention facility may be utilized as a temporary stilling/sedimentation basin for its tributary drainage area, as long as the basin is over excavated to provide the additional volume. The required detention volume must be maintained at all times.
