LeBlanc said those evacuation efforts remained ongoing as of 8:30 p.m.Sky5 captured video of people being evacuated from a Race Street home by a crew on a rescue boat Monday evening. Some vehicles parked in the area were submerged by the water that filled the streets."All sorts of children and people live here, so not a good thing at all," said Lowell resident Walter Smith. "We were listening to some of the fire department and they may need to shut off the electricity to some of these buildings in order to make them safe for the occupants, so that's not a good thing either."The Lowell Police Department first tweeted about the water main break shortly before 5:25 p.m. and advised people to seek alternate routes and expect delays.Lowell police Capt.
