Upper Des Plaines River, Phase II
Project Manager: Buczak, Kirston

Introduction:
 
Welcome to the web site for the Upper Des Plaines River Phase II Project. The Des Plaines River has a long history of flooding that has caused significant economic losses. The maximum flood of record, September 1986, caused 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. The Corps of Engineers is interested in working with state and Federal agencies, local and national groups, and our sponsors to find forward-thinking solutions that meet the needs of all concerned.

Authorization:

Water Resources Development Act 1999, Section 419

Project Description:

The Upper Des Plaines River flows from southeast Wisconsin to northeast Illinois. It is 67 miles long, flowing through 33 municipalities. There is frequent flooding. In 1986, the flood of record occurred and affected 15,000 residents, their dwellings and businesses, as well as the transportation network. This multipurpose study expands the area of concern from the mainstem in Illinois to include the entire Upper Des Plaines watershed, 15 tributaries, 73 municipalities in Illinois and Wisconsin, and includes ecosystem restoration, water quality, recreation and related purposes. Flood damage reduction measures will protect over 2000 residential and commercial structures, with an estimated value in excess of $100M.

Costs:

Current Status:

The Feasibility Cost Sharing Agreement was signed on 27 February 2002. Completed cross section surveys for 15 tributaries. Hydrology and hydraulic models are under development. Aerial mapping for the entire watershed was completed. Ecological and Biological sampling was completed. Environmental Evaluation models are under developement.
