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 Parking Lot 3 Green Infrastructure Retrofit in La Grange (23-IGA-18), in an amount not to exceed $207,000.00
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 Parking Lot 3 Green Infrastructure Retrofit in La Grange (23-IGA-18), in an amount not to exceed $207,000.00.
As detailed in a Report on Green Infrastructure (GI) Project Submittals presented to the Board of Commissioners on December 15, 2022, between May and September 2022 the District solicited GI project proposals from municipalities, townships, and other governmental agencies for District assistance, and received 34 applications. Of the 34 project applications received, the Engineering Department identified 10 initial projects recommended for advancement through partnerships based on the anticipated funding available in 2023 for the District’s stormwater management program and an additional 13 applicant projects as suitable for future GI program partnerships, depending on budget and schedule considerations. At this time 12 of the additional 13 projects, including the subject project, have been reviewed and are ready to proceed for inclusion in the 2023/2024 construction seasons. The remaining project has been paused by the applicant and they may re-apply to include it in our program in the future.
Under this project, the Village proposes to convert one (1) parking lot using permeable pavers, as depicted in the attached exhibit. The project is expected to mitigate flooding in the project area and demonstrate to local residents the benefits of constructing GI. The project will reduce and attenuate stormwater runoff in the vicinity of the project area by providing up to an estimated 37,800 gallons of stormwater storage, which the District will include in its annual reporting to the United States Environmental Protection Agency for the GI portion of the District’s consent decree.
The terms of the IGA will include payment by the District towards construction costs in an amount not to exceed $197,000.00. Additionally, the District is providing separate funds, to be available if needed, to assist with environmental site assessment services in an amount not to exceed $10,000.00. The total project cost, including design and permitting, is $557,700.00. Partial payments to the Village, to be set forth in the IGA, will be made at predefined intervals during construction, which is anticipated to commence in 2024. The Village has contributed to engineering and other design-related costs of the project, will assume responsibility for construction, operation, and maintenance of the project, and be solely responsible for any change orders. The IGA will contain provisions that allow the District to review the project’s design, including the potential application of District biosolids, 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 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 $207,000.00. 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 are being requested in 2024, in Account 501-50000-612400, and are contingent on the Board of Commissioners’ approval of the District’s budget for that year.
Requested, Catherine A. O’Connor, Director of Engineering, KMF:JK
Recommended, Brian A. Perkovich, Executive Director
