The leak caused Church Street between Ocean Boulevard and the Highland Avenue extension to be closed because of flooding in the roadway, according to Hampton police.
High tide on Wednesday and Saturday brought storm surges that inundated streets for several hours, but did not impact overall Unitil gas service, but did submerge meters and regulators.
The NOAA's Advanced Hydrologic Prediction Service shows the ocean cresting at 13.7 feet, nearly three feet above major flood stage. The Portsmouth Naval Shipyard (Seavey Island) crested at 13.17 feet, which is two feet above flood stage.
