A developer approved to build six apartments in Bethel has filed an appeal in state Superior Court, arguing that several conditions attached to the approval amount to a denial of the project. The plan includes two affordable housing units and falls under state law that limits how towns can restrict such developments. The developer claims the town’s requirements involving land rights, traffic sight lines, and protections for nearby wells are unreasonable and cost-prohibitive. Town officials say they are reviewing the appeal and will work toward a resolution as the legal process moves forward.
