Title
Grasslands Subdivision Detention Basin - Proposal
History
In 2005, the Village Board approved Christopher B. Burke Engineering (CBBEL) to complete the engineering for the Grasslands Detention Basin in an effort to mitigate overland flooding within the Grasslands Subdivision. In that time, the initial pond construction (Phase I) has been completed. Dam construction (Phase II) will increase storage capacity to final design parameters. Through the ongoing efforts of CBBEL, Army Corps of Engineers approval was received in late 2009. Final comments from the Illinois Department of Natural Resources (IDNR) were also received at that time.
CBBEL has submitted a proposal to finalize Phase II engineering, complete IDNR permitting and provide construction observation for the dam construction. The additional engineering is required due to significant changes being required by the IDNR.
On May 3, 2010, this item was reviewed and approved by the Public Works and Engineering Committee and referred to the Board for approval.
Financial Impact
There are sufficient funds in the Board approved line item #031-6007-433-3250 to cover the cost of this work.
Recommended Action/Motion
I move to approve accepting the proposal from Christopher B. Burke Engineering (CBBEL) of Rosemont, Illinois, for final design engineering, permitting and construction observation of the Grasslands Flood Control Facility (Dam) in an amount not to exceed $38,300;
And
Approve authorizing the Village Manager to execute the proposal.
