The Inland Wetlands Commission, in a 6-0 vote in a special meeting Thursday, approved the city’s permit application for extension of the roadway, with street construction occurring within regulated wetlands areas. Extending the roadway and use of the Mas property has been on the table for years, but Mayor Mark Lauretti began the most recent push in April when he presented preliminary plans for creating the road leading into the city-owned land, which would be developed into a manufacturing corporate park. Lauretti has stated that one major manufacturer — whose name he would not give because negotiations are ongoing — is seeking a 270,000-square-foot building on the property. Lauretti has stated that the road work would cost between $10 million and $12 million. Bids are out now, he said, and once those come in, he will have a better idea what the state will cover and what the city will pay. He said he expects a groundbreaking for the extension this spring.
