DuPage County Stormwater Management Begins Wetland Map Initiative

DuPage County’s Wetland Map Initiative to provide residents, developers and businesses with updated wetland maps is underway. These enhanced maps will more accurately identify wetland areas currently in existence throughout DuPage County.

The United States Environmental Protection Agency awarded DuPage County Stormwater Management with a Region 5 Wetland Program Development Grant for $118,369 to update the County’s wetland maps. This proactive effort is intended to help property owners, developers and regulators easily assess the presence of wetlands on a property in order to save time and money during permitting and development.

DuPage County developed the current wetland maps in the mid to late 1990s, and they no longer reflect existing conditions because of development. Additionally, wetlands are dynamic systems that can change over time due to factors such as surrounding land uses, hydrologic changes and climatic conditions.

Wetlands, wetland buffers and riparian buffers serve an important function by filtering pollutants from stormwater and storing floodwater. They also serve as a habitat to a variety of organisms and moderate water and air temperature fluctuations, creating a more comfortable atmosphere for wildlife and humans alike.

The project is expected to be completed within 2 years. For more information on the Wetland Map Initiative, click here.
