Stormwater Management

A Message from the Chairman

Jim ZayWelcome 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 stop by often for the latest news,  updates on current projects and more about the 2015 Stormwater Management Program Assessment.

Chairman, Stormwater Management Planning Committee

FEMA Preliminary Floodplain Data

FEMA issued preliminary maps on June 3, 2015, to all communities in DuPage County. Printed floodplain maps were mailed to the CEO of each community along with a disc containing the FIS report, FIRM database, and Preliminary Summary of Map Actions (PSOMAs) lists. Stormwater Management and GIS staff have created a web application that allows the public to quickly compare the new preliminary data to the effective DuPage County DFIRMs. To visit this application, please follow this link, Preliminary DFIRM Map Compare. For more information please visit the County's Preliminary Data Webpage.
