BOARD/COMMISSION REVIEW:
N/A
BACKGROUND:
The City currently has a sales agreement with Gorman to sell approximately 4.01 acres of the vacant land located at the southeast corner of Route 59 and 103rd Street, commonly referred to as the Naperville South 40. The Gorman site will potentially be developed with an affordable housing complex to address a community need. Due to affordable housing grant funding Gorman plans to use, the site is required to be environmentally clean.
On April 11, 2024, the City awarded Bid 24-048 to Gold Wave, Inc. to complete soil investigations and perform professional services necessary to apply to the Illinois Environmental Protection Agency (IEPA) for a No Further Remediation Letter (NFR) for the site. The City retained Gold Wave, Inc. to perform Phase I and Phase II environmental testing at the site.
DISCUSSION:
Gold Wave, Inc. enrolled the site in the IEPA Site Remediation Program (SRP). As part of this effort, Gold Wave, Inc. installed groundwater monitoring wells, collected soil samples, observed and documented soil removal and remediation activities, and prepared a comprehensive report of findings. This report was submitted to the IEPA on July 17, 2025, for review in pursuit of an NFR letter.
The IEPA completed its initial review of the report on September 30, 2025, and issued a response letter identifying comments that required additional soil sampling, groundwater investigation, and laboratory analysis. These items were required to be addressed and incorporated into a revised report prior to resubmittal. Follow-up meetings were subsequently held between the City, Gold Wave, and the IEPA to clarify the agency’s comments and expectations.
Throughout this process, the City has worked closely with Gold Wave, Inc. to expedite soil sampling, laboratory analysis, and IEPA reviews in order to support the Gorman project deadlines associated with the grant funding. Based on ongoing coordination with Gorman, the City and Gold Wave, Inc. have identified approval of the Remedial Action Plan (RAP) as the primary remaining requirement for approval of the grant funding. Approval will in turn allow the development to proceed to construction. The RAP outlines a detailed strategy for conducting any required site remediation and is a critical component of the application process for obtaining an NFR letter.
Gold Wave, Inc. completed the requested additional work in a timely manner and incorporated the results into a revised report, which was resubmitted to the IEPA under an expedited review timeframe on December 3, 2025. The IEPA completed its review and issued an additional response letter on December 22, 2025, identifying comments that will require further work to obtain RAP approval. Once the RAP is ultimately approved, additional work will be required to complete the site remediation in order to obtain the NFR letter.
On December 26, 2025 the Chief Procurement Officer authorized Change Order #1 to add $5,700.35 to the contract to pay an outstanding invoice.
This Change Order covers professional services required to analyze and document findings completed to date.
