Message from Stormwater Management Planning Committee Chairman, Jim Zay
As Chairman of the Stormwater Management Planning Committee, I work with my colleagues on the Committee, municipalities, the County Board and Stormwater staff to ensure the development of sound policies and practices regarding stormwater management. We work to protect the health, life and property of DuPage County residents and businesses from the devastating effects of flooding. We also work to improve the quality of our stormwater runoff and local waterways through compliance with our National Pollutant Discharge Elimination System permit for Municipal Separate Storm Sewer Systems. We are continually striving to ensure DuPage County remains a great place to live, work and raise a family. Thanks for visiting our page and be sure to stop by often for updates.
