Since its inception, DuPage County Stormwater Management has created and implemented the long-standing DuPage County Countywide Stormwater and Floodplain Ordinance, which has helped mitigate the effects of rapid development on stormwater runoff. Throughout this time, SWM has also constructed 17 flood control facilities countywide to protect existing structures from the effects of overbank flooding. In addition to the regulatory services, watershed management and operations, DuPage County has developed robust water quality and floodplain mapping programs, both of which strive to protect and enhance the quality of life for DuPage County residents.
