COLCHESTER — A preliminary concept for a large data center on Old Amston Road has drawn public opposition, but town records show the project has not yet reached the formal application and public-hearing stage.
The Planning and Zoning Commission reviewed the idea on September 16 at the request of CMMD LLC. Official minutes describe a site at 42 Old Amston Road in the Rural District and a possible zoning change that would allow a data center through a special-permit process.
The concept presented to commissioners included two buildings totaling 399,920 square feet. The representative projected about 350 construction jobs over four years and 80 to 100 permanent jobs. Commissioners raised questions about environmental effects, water demand, noise and whether the proposed zoning language would blur the distinction between rural and industrial districts.
In an October 2 report, First Selectman Bernie Dennler said the developer intended to apply under the town’s large-scale indoor agriculture and technology regulations. He also said associated fuel cells would fall under the Connecticut Siting Council rather than the town commission.
WFSB reported that residents packed an October 6 public meeting and raised concerns about the proposed location, environmental effects and how the concept had advanced without broader public awareness. The opposition meeting did not itself approve or reject the project.
The town says every zone-change application requires a Planning and Zoning Commission public hearing. The applicant would have to notify property owners within the proposed change area and within 500 feet. Residents may also submit correspondence to the commission before a formal hearing is scheduled.
The commission’s October 7 minutes list other land-use matters and do not record action on a formal data-center application. That absence, together with the town’s published explanation, means the preliminary concept should not be described as approved or under construction. A later filing, legal notice and hearing record are needed to establish the next step.
