Marseilles Council OKs Constellation Annexation, Approves $10M Payment and 40‑Year Tax‑Rebate Structure

Marseilles — The Marseilles City Council on an Aug. 30 special meeting adopted an annexation agreement with Constellation Energy Generation LLC that brings roughly 715 acres into the city and obligates Constellation to pay $10 million to the city over five years. The council approved the resolution authorizing the agreement and an ordinance annexing the territory, each by a 4–1 vote.

The agreement, summarized by Gregory Smith, outside legal counsel for Constellation, requires Constellation to make scheduled payments totaling $10,000,000 over five years (approximately $3,000,000 in years 1 and 2, $2,000,000 in year 3, and $1,000,000 in years 4 and 5, with deductions in the final two years for property and utility taxes paid). Smith told the hearing that “the $10,000,000 worth of payments by Constellation will be made even if no development occurs on the property.” The annexation term in the agreement is 20 years.

The agreement also establishes a set of tax‑rebate conditions that would return some new revenues to Constellation only after the city reaches revenue thresholds. Under the terms explained by Smith, property‑tax rebates would begin only after the city receives $2,500,000 in property taxes in a year, utility‑tax rebates after $5,000,000 in utility tax revenue, and sales taxes would be split 75%/25% up to an annual cap of $1,200,000 (with amounts above the cap fully rebated). The rebate provisions run for 40 years, the company said.

Constellation officials described the annexation as a way to create an "emerging technology" district for a range of uses — electronics manufacturing, storage, fabrication, data centers, research and lab facilities, offices and power generation — and said the zoning and comprehensive plan changes included in the agreement are intended to provide certainty for potential customers. Ryan Tozer, Constellation’s local government affairs manager, said the company does not yet have a customer for the site and that the annexation is intended to make the property more competitive.

Public commenters expressed both support and concern. Supporters including trades representatives and business groups said the annexation could deliver construction and long‑term operations jobs and new revenue for infrastructure. IBEW Local 176 member Floyd Jones told the council the project would create “hundreds of good paying construction jobs” and support local businesses. Several residents urged the council to proceed, pointing to long periods of economic decline and needs such as lead service‑line replacement and sewer upgrades.

Opponents and skeptical residents raised environmental and process concerns. Kate Quigley and Heidi Henry questioned whether environmental studies (wetlands, watershed, LIDAR) had been completed and urged protections for wells and rural quality of life. Jonathan Deering asked about existing lease arrangements near the training center. Commissioner Schott, who voted no, said a single public hearing and an immediate vote were insufficient for a decision of this scale and expressed concern about long rebate terms, potential housing and affordability effects, and unknown future uses if a customer is not yet identified.

City officials and Constellation representatives said development would be subject to city, state and federal permitting and to updated building codes listed in the agreement. Smith said that extensions of water and sewer necessary to serve any development would be funded by Constellation; he also said development must comply with the codes the agreement adopts. The agreement includes a tenant‑improvement permit fee and requires reimbursements to the city for third‑party plan review costs.

On the floor, Commissioner Kaminski moved the resolution authorizing execution of the annexation agreement; Commissioner Buckingham seconded. The council recorded Ayes from Commissioners Kaminski, Small, Buckingham and Mayor Hollenbeck; Commissioner Shibe (Schott) voted No. The ordinance annexing the territory was adopted later in the meeting with the same 4–1 tally.

What happens next: The annexation agreement calls for the city to amend its comprehensive plan and zoning code to create the new emerging technology district and to adopt the building codes specified in the contract. City staff and Constellation said they will continue to respond to public questions and that specific development proposals would return to city review and permitting processes before construction begins.
