Where can I find more information on the stormwater rules and regulations?
Illinois Drainage Law: http://www.aces.uiuc.edu/vista/abstracts/aDRAINAGE98.html IEPA NPDES Regulations: http://www.epa.state.il.us/water/permits/storm-water/index.html US EPA NPDES regulations: http://cfpub2.epa.gov/npdes/ City of Rock Island Stormwater Control Ordinance: http://www2.rigov.org/pdf/stormwater/stormwatercontrolordinance.pdf • How do I know if I need a storm water (grading and drainage) permit? There is a checklist on the permit application. If your project adds 500 SF or more of impervious area, disturbs an area 10,000 SF or more, disturbs a volume more than 100 CY, or is located on or next to a slope 7% or greater, a storm water permit is needed. If your project is close to these triggers, you should submit a permit application. That way the City knows if a permit is needed or not. Also building permits are not issued until you have complied with the storm water requirements. City staff can help determine if a permit is needed. For more information, see the storm water
