Ridgefield is looking into the potential sale of the soon to be decommissioned District II sewage treatment plant. Upgrades are being made to the District 1 plant to accommodate the entire town. Negotiations are underway with Ridgefield Professional Office Complex, LLC to buy the Ethan Allen Highway parcel. The entity owns a triangular parcel of land between Routes 35 and 7, including Little Pond and a nearby medical office complex. The two acres in the middle of the parcel contains the sewer plant, and is owned by the town. A “pre-concept” for a residential project has been presented to the Planning and Zoning Commission for two attached sets of homes, if the zone is changed to residential. The site has been appraised at $441,000.
