Danbury’s Zoning Commission has approved a land use change to allow 225 apartments on a 27-acre wooded site off Saw Mill Road near the New York line. The unanimous vote follows a pitch from former Waterbury Mayor Neil O’Leary, now a consultant on the project. Blasius Enterprises, which bought the land for $2.3 million, will now move forward with site plans. Officials say multifamily housing fits the area better than industrial use, but critics warn it could worsen traffic and strain city services.
