The study area is within the City of Joliet, Will County, Illinois.  The City of Joliet is bisected by the Des Plaines River.  The west side of Joliet is on relatively high ground.  The east side is low-lying.  In some areas, downtown Joliet is more than 15 feet below the 100-year (1% annual chance exceedance) flood elevation of the Des Plaines River. The area historically has been protected from flooding on the left descending bank of the river (east side) by a combination of the channel wall that is part of the lock and dam system and non-engineered embankments. This projects seeks to identify structural and non-structural measures to reduce flood risk associated with the Des Plaines River overbank flooding. In addition, it will identify measures to improve community awareness of flood risk and the ability to respond to flood emergencies.
