A wave of voters toppled three of five Festus City Council members on Tuesday, delivering a landslide to newcomer Rick Belleville, who beat incumbent Jim Tinnin by more than 40 points. The upset followed a surge in turnout fueled by anger over the city’s handling of a proposed 360‑acre data center on its southwest side. Residents complained the approval process lacked transparency and ignored concerns.

A lawsuit filed Thursday targets the city and CRG, the Clayco affiliate that negotiated the 360‑acre deal. Plaintiffs such as homeowner Sherman Boyle claim the agreement could raise electric rates, strain water resources and enable voluntary buyouts of properties. An action committee supporting the ousted incumbents pumped almost $40,000 into ads, while activists started a recall drive against Mayor Sam Richards and the council members.

The election outcome sends a clear signal that Festus residents will not tolerate opaque development deals. With the council reshaped, city officials face immediate pressure to renegotiate the data center agreement, address utility impact concerns, and halt the recall effort that could unseat the mayor. The next weeks will determine whether transparency becomes a governing standard in Jefferson County.
