FAIRFIELD — More than 150 people have signed a petition to repeal state statute 8-30g and stop an affordable housing development proposed for Unquowa Road. As of Friday afternoon, approximately 200 people had signed the petition, which says the “state needs to scrap the 8-30g state statute and replace it with a program that helps towns build their own affordable housing, and allows our organic, affordable middle housing to be included in the state’s metrics.”
