A Message from the Chairman
Welcome to Stormwater Management's webpage. Since the inception of DuPage County Stormwater Management 27 years ago, the County has been at the forefront of regional stormwater planning. As Chairman of the Stormwater Management Planning Committee, I work with the
County Board, municipalities and staff to ensure DuPage County is providing its residents with the highest quality stormwater management in the department's five program areas-Watershed Management, Floodplain Mapping, Water Quality, Regulatory Services and Flood Operations.
I encourage you to explore Stormwater Management's ongoing regional projects and initiatives, including information on how you can become involved in preserving and enhancing our waterways. Together, we can ensure DuPage County remains a top-tier community
to live, work and raise a family. Thank you for taking the time to visit Stormwater Management's webpage, and I encourage you to read the
2016 Stormwater Management Annual Report to learn more

FEMA Preliminary Floodplain Data
FEMA issued preliminary maps on June 3, 2015 to all communities in DuPage County. DuPage County Stormwater Management and the County's GIS staff have created the
Preliminary DFIRM Map Compare web application to quickly compare the new FEMA preliminary data to the effective DuPage County DFIRMs. For more information, please visit
