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
2017 Stormwater Management Annual Report to learn more.
Chairman, Stormwater Management Planning Committee
FEMA Preliminary Floodplain Data
The Federal Emergency Management Agency (FEMA) is expected to publish DuPage County’s revised preliminary floodplain maps in mid-2019. During public review, FEMA and the Illinois State Water Survey resolved more than 120 comments and one appeal to the maps. As a result, some Flood Insurance Rate Map (FIRM) panels and the Flood Insurance Study (FIS) have been updated. To see how these resolutions are reflected on the FIRMs and in the FIS, visit http://www.illinoisfloodmaps.org/dfirm.aspx?county=dupage.
