Zoning panel recommends Commerce Street Solar project with conditions

The Iroquois County Zoning Board of Appeals recommended approval Sept. 23 of a conditional use permit for Commerce Street Solar LLC to build a community solar facility on roughly 33 acres of an 85‑acre parcel near Gilman, sending its recommendation and draft conditions to the Iroquois County Board for final action.

The recommendation matters because the project would convert farmland acreage to a utility‑scale community solar site that the developer says will provide subscriber discounts to Ameren customers, add recurring property tax revenue and create short‑term construction jobs while requiring long‑term decommissioning and drainage protections.

Commerce Street Solar LLC, represented by attorney Kyle Berry of Maguire Woods, presented a plan that locates arrays on the eastern portion of an 85‑acre parcel, leaving about 50 acres in agricultural use. Developer testimony said the layout includes a gravel access road from North Palmer Street, about seven utility poles along the access, a perimeter 8‑foot chain‑link security fence, a vegetative buffer of trees and a pollinator‑friendly native ground cover under panels. The project proponents said the inverters and transformers — the equipment most likely to produce noise — will be placed centrally and are expected to produce about 35 decibels at their source, roughly a whisper.

Project proponents told the board they have a road‑use agreement with the City of Gilman to route construction traffic from Interstate 57 and state routes into the city and north on Commerce Street to the project access. They estimated peak construction would use roughly 50 equipment deliveries plus about 15 additional trucks for site work, with long‑term operations requiring only intermittent maintenance visits.

The developer described several mitigation measures included in the application: an Agricultural Impact Mitigation Agreement with the State of Illinois, an archaeological survey cleared by the state preservation office, a commitment that project equipment is UL‑certified, and a decommissioning plan with the developer posting financial assurance to cover removal of equipment, fencing and restoration of topsoil at the end of the project. The developer said it would post an amount the county requested to cover full decommissioning costs before a building permit is issued.

Drainage was a focus during questioning. A licensed professional surveyor and engineer on the developer’s team reported a drain‑tile investigation that identified existing clay tile on the property; the contractor described its field methods and said found tiles would be documented and GPS‑mapped. The applicant confirmed any drain tile damaged during construction would be repaired and that replacement pipe would be dual‑wall plastic sized per the replacement plan.

The board reviewed draft findings and a set of recommended conditions before voting. Key recommended conditions forwarded to the county board include: full financial assurance for decommissioning to be posted before a building permit is issued; a requirement to reimburse local emergency responders for costs of emergency response to the site; submission of the drain‑tile survey and agreement to repair damaged tiles; a road‑use agreement and repair obligations for any construction damage to local roads; and a prohibition on battery storage at the site. The board also included a local‑hiring preference language asking the applicant to consider contractors within a 100‑mile radius.

Developer Jennifer (director of development, Solitude LLC) summarized environmental practices and local sourcing plans: “We’re also just gonna source all of our vegetation, including the ground cover and the vegetative buffer, through a local nursery,” she told the board. Engineer Daniel Flaylock described site layout and traffic expectations and said, “once construction project is complete and the project is in operation, we only will have folks going out there, very intermittently for maintenance purposes.”

The board formally voted to adopt the draft conditions and to recommend approval of the conditional use permit with those conditions. The Zoning Board of Appeals decision is only advisory; the Iroquois County Board will consider the full record and the recommendation at a later meeting.

Next steps: the hearing transcript and exhibits will be provided to the county board; the county board will make the final decision on the conditional use permit and any changes to the recommended conditions.
