Stormwater Regulatory Services
The mission of the Stormwater Regulatory Division is to remain competitive in maintaining and attracting businesses, while also protecting natural resources and minimizing stormwater damage in DuPage County. We regulate and monitor new development or
redevelopment through enforcement of the DuPage County Countywide Stormwater and Floodplain Ordinance (Ordinance). The Ordinance promotes effective, equitable, acceptable and legal stormwater management measures in DuPage County. The County reviews
Stormwater Management Certification Applications for developments impacting special management areas. In addition, the County reviews applications for developments requiring stormwater management in certain communities.
