Unless judged by the village to be exempt or granted a waiver, the following performance criteria shall be addressed for storm water management at all sites:
(A) All site designs shall, to the maximum extent possible, establish storm water management practices to control the peak flow rates of storm water discharge associated with specified design storms and reduce the generation of storm water runoff. These practices should seek to utilize pervious areas for storm water treatment and to infiltrate storm water runoff from driveways, sidewalks, rooftops, parking lots, and landscaped areas to the maximum extent practical.
(B) To protect stream channels from degradation, a specific channel protection criterion shall be provided as prescribed in the Illinois Urban Manual.
(C) Certain industrial sites are required to prepare and implement a storm water pollution prevention plan, and shall file a notice of intent (NOI) under the provisions of the National Pollutant Discharge Elimination System (NPDES) general permit. The Storm Water Pollution Prevention Plan requirement applies to both existing and new industrial sites.
(D) Prior to design, applicants are required to consult with the village to determine if they are subject to additional storm water design requirements.
(E) The calculations for determining peak flows as required by the MWRDGC shall be used for sizing all storm water management practices where applicable.
