NORTH ANDOVER — Pentucket Bank’s plan to build a branch office at the Butcher Boy Plaza faces a drainage challenge.
State Department of Environmental Protection regulations require that the amount of water from the plaza flowing into nearby Lake Cochichewick remain the same, according to Planning Board members. The runoff must also be pollution-free, they said.
Lake Cochichewick is the source of North Andover’s drinking water. The regulations apply to any project that is within 400 feet of a water supply, Town Planner Judy Tymon said.
Pentucket’s drainage plan calls for an underground detention system that would filter the runoff from the site — but more water would still end up in Lake Cochichewick, Tymon said. She told the Planning Board last night she, Lisa Eggleston, an environmental engineer who advises the town on drainage plans and Richard Barthelmes, engineer for Pentucket Bank, will meet next week in an attempt to resolve the dilemma.
Barthelmes said the manufacturer of the drainage system he proposes insists it will function properly, but DEP does not agree.
He told the board he complied with the board’s request that a traffic study of the site be done while school was in session. He estimated the bank will result in another 500 trips per day along Route 125. Butcher Boy Plaza is at Routes 125 and 133.
Customers will have to get to the bank by entering the plaza parking lot from Route 125. There will be no access from Route 133.
The bank’s plans include 21 parking spaces for customers, Barthelmes said.
Scott Cote, president and chief executive officer of Pentucket, said the bank has a “handful” of customers in North Andover. Once the branch office is built, the bank hopes to attract more customers, he said.
The Planning Board continued the hearing until Aug. 6.
