Residents pushed back against an affordable housing project to add 40 apartments on Berkeley Road saying the project is too big for the area, which is already busy and full of smaller lots. The proposed 34,000-square-foot building at 277 to 301 Berkeley Road would be about 47 feet tall on one side and about 60 feet tall on the other, given the slope in the property. John Fallon, the attorney for the developer, Berkeley Rd. LLC., said he believed the parking would be sufficient and would remove the cars parked in front of the proposed site because the tenants would park in the designated lots. He said the project is needed and helps address Fairfield’s housing needs, since a third of the town’s households are housing cost burdened, meaning more than a third of their income is spent on housing.
