Sargent said the town and Creighton Manning have had agreements spanning three years to help update the GEIS.
"We're trying to identify a long-term vision for infrastructure in the area. And how does it accommodate the different land uses proposals and potential development," Sargent said. "We are hearing about some specific issues that town wants us to look into."
He said part of the work is to help find alternatives to making Route 9 wider, since that proposal was not met with support from the department of transportation, and Creighton Manning is working closely with Clough, Harbor and Associates to work on the project.
