Age-targeted is for renters ages 52 to 55 and age-restricted is for tenants older than 55. The need for senior housing has been recognized for years in the community where seniors are the fastest-growing demographic. During the first in-person Board of Selectmen meeting in more than a year, First Selectman Daniel V. Jerram said Monday work on the proposal has been going on behind closed doors for three years. The developer is seeking a tax abatement for the project, which could cost $18 million. Jerram said the property under consideration is open space and generates only $500 in tax revenue annually. If an abatement were approved, it could be for any period up to 20 years and be phased out in stages. The developer reportedly wants to build the project over time, with perhaps 40 units in the first phase, another 40 in the second wave and the remainder later.
