Hickory Spring Creeks Project 

Hickory Creek Flood Damages

A 1957 flood left $56 million in damage (in 2010 dollars) in the Hickory and Spring Creek watersheds, while in 1980 high water caused another $44 million in damages (again, in current dollars). These projects will provide additional conveyance for flood waters by lowering and widening the channel. Indeed, the construction of the first phases of the project on Hickory Creek appears to have kept damages down significantly during the 1996 flood event that inflicted extensive damage elsewhere in the Chicago area.


Project Description

The Hickory and Spring Creeks watershed plan includes Sauk Trail Reservoir and channel alterations. Extensive channel alterations to Hickory & Spring Creeks include the lowering of the channel invert in rock, construction of concrete walls, and replacement of bridges increasing  channel capacity to be capable of carrying the 100-year frequency flood within channel banks. The project has been separated into stages to facilitate construction funding and continuity.

When completed, 1500 structures are expected to be removed from flood damages with an Average Annual Benefit of over $508,000.

Flood Control B/C Ratio = 0.3/1 (based on 1983 estimates).

The project requires a new Corps 404 permit and the complete application has been submitted.  OWR is working  with the U.S. Army Corps and USFW for approval of Mitigation Plan for permit approval.

The first phase of construction was initiated during FY-78 on Sauk Trail Reservoir, which was completed in FY-81.  

Stages I, IIa, IIb, IIb1, IIb2, IIIA and IIIb1 of the channel improvement of Hickory Creek are complete.

Stage I channel construction started in FY 85 and was completed in September 1988. 

Stage II activities started with P&S and Engineering in FY 86 and continued with work on the railroad bridge over Hickory Creek (FR 358) and the new Gardner Street bridge (FR 359) which included channel work from the railroad bridge to I-80.  Final work on this contract completed in FY 98. 

OWR let Stage II b2 contract (FR 387) in April of 2000 and Stage III A, (FR 364) in FY 2001. 

Stage IIIB2 all Right-Of-Way acquired and Plans & Specs are 85% complete. 

Under an agreement with the Illinois Department of Transportation (DOT), DOT incorporated the Draper Ave. channel work into their road improvement plans. Office of Water Resources paid $327,000 for the flood protection aspects of the work.

Construction plans were revised for Stage III b to incorporate only the 4th Ave. bridge and as much work upstream as current available funding allowed. Natural History Survey completed wetland delineation. Fisheries completed a fish survey throughout the watershed including the already constructed reach.

The Corps of Engineers’ permit for this project expired December 31, 2005 and a new 404 permit is being pursued. Additional alternatives, diversions and reservoirs were investigated for the 404 permit application package. This analysis showed that the most feasible plan for Hickory Creek is the originally proposed channel modification. Analysis for Spring Creek needs to be completed. Current conditions floodplain maps are being prepared for the City of Joliet to update FIS.

Construction is complete for Stage II b2 and Stage IIIA.  Due to the lapse of part of the project funds in FY 03, the construction plans were revised for Stage III b to incorporate only the 4th Ave. bridge and as much work upstream as current available funding allowed.
