A. Requirements: The applicant shall also submit a separate plan labeled “Stormwater Pollution Prevention Plan” which identifies the practices to be used to control runoff, erosion, sedimentation and drainage expected to occur while the project is ongoing, and before final grading, that may adversely impact adjacent properties or public rights of way. The stormwater pollution prevention plan shall also include:
1. A specific plan to eliminate the adverse impacts from stormwater runoff, including, but not limited to, interim soil stabilization and proposed erosion and sediment control practices for all times during construction work and specifically during demolition; between completion of demolition and the commencement of construction work; and continuing through the construction work, until final grading and establishment of a minimum of 70 percent of the permanent vegetation. All such proposed measures shall be based upon the standards and requirements contained in the latest edition of the “Illinois Urban Manual.”
2. Details regarding the intended interim on site storage, placement, fill and disposal of earth materials;
3. Location of the proposed areas of excavation, fill, storage and disposal of earth materials, including an appropriate method of erosion and sediment control practices;
4. Location of flood protection areas;
5. Delineation and standard details of the measures that will be used to control surface erosion and runoff from the site after all buildings, structures and permanent improvements have been erected on the site;
6. Location of temporary stockpiles; and
7. Location of stabilized construction entrance.
B. Final Stabilization: To the extent the Director of Public Works and Development Services determines that the proposed final grade, land contour or drainage pattern may, upon project completion, adversely impact adjacent properties or public rights of way, the site grading plan shall also include:
1. Data regarding the classification, distribution, strength and erodability of existing soils;
2. Data regarding the nature, distribution, strength and erodability of earth materials, if any are to be placed on the site;
3. Level of water table;
4. Plans for permanent soil stabilization upon project completion;
5. Design criteria for corrective measures, when necessary; and
6. An alternate proposal for final grading that will eliminate the identified adverse impacts.
C. Inspection requirements for all ground disturbances, following the inspection requirements established in the IEPA ILR10 general permit conditions. All reports and correspondence related to these inspections and following actions shall be provided to the Village. (Ord. 3877, 11-14-2022)
