Location and Description:  The East St. Louis levee system is located in St. Clair and Madison Counties, Illinois, along the left descending bank of the Mississippi River between river miles 175 and 195 above the Ohio River. The levee system was designed to withstand a flood at 52 feet on the St. Louis gage; approximately a 0.2 percent chance of exceedance (500-year event) and provides flood protection to approximately 200,000 residents and over $1 billion in economic value. The system is aged and requires rehabilitation. The East St. Louis, Illinois, project consists of the rehabilitation and/or closure of 21 small gravity drains, 10 large gravity drains (gatewells), 20 closure structures, and 300 relief wells; minor floodwall and levee rehabilitation work; rehabilitation of 12 pumping stations and 3 drainage control structures; replacement of 3 bridge structures; abandonment and removal of 4 bridge structures; and 6 segments of channel rehabilitation. All bridge work is 100 percent non-Federal ($3,958,000). The rehabilitation project also includes the development of a Limited Reevaluation Report (LRR) that addresses design deficiencies in underseepage and through seepage controls.  

Activities in FY 2010 ($500k)
- Complete subsurface investigations and underseepage analyses so Limited Reevaluation Report (LRR) will be based on current geotechnical data
- Continue work on LRR that addresses design deficiencies in underseepage and through seepage controls
- Continued construction at North Pump Station
- Execute a Project Partnership Agreement
