Stormwater Permit Application Submittal Update

Due to the containment efforts to control COVID-19, DuPage County Stormwater Management will not be able to process any paper copies of stormwater permit applications effective immediately until further notice. If an applicant wishes to submit electronically, those reviews will continue to be processed. If an applicant previously submitted a paper copy, please note that a resubmittal may be made electronically using the assigned tracking number for the development. Electronic submittals and instructions

Additionally, submittal review times will be adjusted as necessary to accommodate the rapidly evolving response to COVID-19.

Thank you for your patience and understanding.


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.
