The New Jersey-based development company behind the Merritt 8 Corporate Park is aiming to build a 129-unit apartment complex on the same site. Mountain Development Corporation is seeking the town’s approval to construct the four-story building on a largely-undeveloped plot of land off Hawley Lane, according to an application submitted to the town. The application is currently before the Stratford Inland Wetlands Commission, a seven-member board charged with determining whether construction projects adhere to local environmental regulations. Kelly Kerrigan, Stratford’s environmental conservation superintendent, said the commission could vote on the application as soon as Wednesday. If approved, the proposal would then move to the zoning commission. Municipalities can only deny 8-30g applications if the project would cause a substantial health or safety concern. Developers, meanwhile, can only take advantage of the law if less than 10 percent of a municipality’s housing units are designated by deed as affordable.
