Prairie Du Pont Project

IDNR Storm Sewer Survey

At the request of the Cities of East St. Louis and the City of Cahokia Heights, the Illinois Department of Natural Resources conducted a survey of elements of the storm sewer system in the several neighborhoods that suffer repeated flooding. The storm sewer survey is intended to provide information on existing infrastructure conditions so the community can make informed decisions about how to fix the stormwater flooding problems. HeartLands Conservancy is providing a link to IDNR’s survey information viewer to make it easy for Prairie du Pont watershed stakeholders to access the information.
