Des Plaines River - Phase I


Water Resources Development Act 1999 (Public Law 106-53)

Project Description:

The Des Plaines River has a long history of flooding that has caused significant economic losses. The maximum flood of record occurred in September 1986 with an estimated $35 million in damage to 10,000 dwellings and 263 business and industrial sites. More than 15,000 residents were evacuated from the flooded area and seven lives were lost. Severe impacts to transportation networks were also identified in this area of 33 municipalities along 67 miles of river in two counties.

The flood damage reduction project consists of six structural elements: two levees, two expansions of existing reservoirs, one lateral storage area, and one dam modification. The levee projects include a flood warning system. Work involves construction of the Mount Prospect/Prospect Heights Levee, also known as Levee 37; the Rand Park Levee, also known as Levee 50; the Buffalo Creek Reservoir expansion; the Big Bend Lake expansion; the Van Patten Woods lateral storage area; and the North Fork Mill Creek dam modification.


Total Project Cost:   $ 103,000,000
Federal Cost:   $ 67,000,000
Non-Federal Cost:   $ 36,000,000

Current Status:

Levee 37 Gaps and Closures contract has completed work on closing the gap, installing a closure structure along Palatine Road, and other minor efforts that help finish the project. One final closure structure on Milwaukee Avenue is currently in our contracting phase with work to be completed in summer 2016.

Van Patten Woods Lateral Storage was rejected by the Lake County Forest Preserve District as a possible project and now joins the other four recommended projects as on permanent hold until a final decision can be made about their future.
