Title
156th Street Extension (LaGrange Road to South Ravinia Avenue) Wetland Mitigation - Board Approval
History
In 2005, the Board of Trustees approved awarding an engineering contract to Smith Engineering Consultants, Inc. (SEC) of New Lenox, Illinois, for engineering services for the construction of 156th Street between LaGrange Road and Ravinia Avenue.
The proposed 156th Street extension will require that a wetland be crossed impacting approximately 0.85 acres of wetland. Nontoxic clean fill is being added to the wetland to facilitate construction of the roadway. Alternatives have been explored and SEC has recommended the purchase of wetland mitigation bank credits within the required Des Plaines Watershed. This mitigation is required as a condition of issuance of the U.S. Army Corps of Engineers permit for the project.
To compensate for the 0.85 acre wetland impact, SEC is proposing to purchase 0.85 acres mitigation bank credits at Des Plaines Towpath Wetland Mitigation Bank in Channahon, Illinois, owned by Towpath Joint Venture of Bloomington, Indiana. The cost of the wetland bank credit is $100,000 per acre for a total cost of $85,000.
On March 8, 2010, this item was reviewed and approved by the Public Works and Engineering Committee and referred to the Board for approval.
