Title
Authority to negotiate and enter into an Intergovernmental Agreement with and make payment to the Village of La Grange for the design, construction, operation, and maintenance of the 50th Street Storm Sewer Flood Relief Project in La Grange (26-IGA-12), in an amount not to exceed $15,314,000.00
Body
Dear Sir:
Authorization is requested to negotiate and enter into an Intergovernmental Agreement (IGA) with and make payment to the Village of La Grange (Village) for the design, construction, operation, and maintenance of the 50th Street Storm Sewer Flood Relief Project in La Grange (26-IGA-12), in an amount not to exceed $15,314,000.00.
On September 17, 2019, the Board of Commissioners authorized the District to negotiate an IGA with the Village of La Grange to partner on a local flood control project under the District’s Stormwater Management Phase II Program. Over the last several years, the Village continued reviewing alternative flood control projects and settled on a project to separate a portion of its combined sewers and connect to a new trunk sewer on 50th Street, from 8th Avenue to East Avenue. The project includes lateral storm sewers extending out from the new trunk sewer, to drain several low-lying depressional areas. This project will alleviate overland flooding for an estimated 132 residential structures and will also alleviate basement backups by reducing the quantity of stormwater going to the combined sewer system and TARP.
The Village has developed plans for the sewer improvements, and it is recommended that the District contribute towards the cost of the proposed storm sewer laterals, after the trunk sewer is constructed by the Village. Based on information provided by the Village, the overall cost of the project is $37,803,000.00 and the estimated District contribution for the laterals is $15,314,000.00. The Village would be responsible for design and permitting of the project, and will assume responsibility for its construction, operation, and maintenance of the project. The Village will also be solely responsible for any change orders. The IGA will contain provisions that allow the District to review the project’s design and perform inspections after construction. The IGA will also require the Village to advertise and award the construction contracts in conformance with the District’s Purchasing Act, Multi-Project Labor Agreement, and Affirmative Action Requirements.
The Affirmative Action goals to be applied will conform with the current requirements of the District’s Appendix D upon execution of this IGA. After construction, the Affirmative Action utilization on this project will be provided in an annual report summarizing goal attainment on stormwater partnerships.
Based on the foregoing, it is requested that the Board of Commissioners grant authority for the District to negotiate and enter into an IGA with and make payment to the Village in an amount not to exceed $15,314,000.00. It is further requested that the Chairman of the Committee on Finance, Executive Director, and Clerk be authorized to execute said agreement on behalf of the District, as well as any documents necessary to effectuate the transaction and conveyance, upon approval by the Director of Engineering as to technical matters and by the General Counsel as to form and legality.
Funds in the amount of $15,314,000.00 are anticipated to be spent over a three-year period, in accordance with the agreement after it is executed. Funds from Account 501-50000-612400 requested in future years are contingent on the Board of Commissioners’ approval of the District’s budget for those years.
Requested, Catherine A. O’Connor, Director of Engineering, KMF
Recommended, John P. Murray, Executive Director
