No Data Summary
General text description of the levee system with a summary of why the levee is there, and the benefits it provides.
Levee 37 is a three segment system that was constructed along the west bank of the Des Plaines River. The levee is considered three segments because the levee spans two municipalities; Prospect Heights to the north and Mt. Prospect to the south, split at Old Willow Road and includes a non-project segment along the expressway. It reduces flood risk of the leveed area to over 600 structures as shown to the right. The levee was constructed in phases from 2008 to 2017 by the U.S. Army Corps of Engineers (Corps). It consists of almost 9,000 feet of concrete and sheetpile floodwall, with short portions of compacted clay embankment about 700 feet long to tie the wall into high ground. The Palatine Road embankment also acts as part of the levee. There is one road closure gate at Milwaukee Road north of Palatine Rd bridge which is closed during more extreme events. Three pump stations reduce interior flooding, but do not eliminate nuisance ponding on the landside of the levee.
Performance & Condition
General text description of the historical and anticipated performance of the levee, the people and property benefitting from the levee and who may be at risk of flooding, and actions to address areas of concern.
The Corps completed a risk assessment for each of the Levee 37 Segments in 2015. The levee has performed well, including in April 2013 when the local municipalities had to flood-fight the last gap left in the wall before it was finished the following year. The overall condition of Levee 37 is sufficient, but limitations for risk reduction remain. Any given year could result in a flood which the levee is not designed to handle.
