Selectman Robert Haverty said officials must be mindful of how updating floodplain maps could affect insurance expenses for homeowners in the watershed.
“We ought to be prepared to understand what that means to some residents,” Haverty said.
Sherman commended selectmen, Gowan and Town Administrator Tom Gaydos for launching a committee that included residents that led to the study.
Sherman said officials got a federal grant so local taxpayers didn’t have to carry the cost.
He said Pelham officials had helped to get something started to deal with the flooding problem.
