Several Cape Cod and South Coast communities in Massachusetts are still digging out three days after a historic blizzard buried neighborhoods in several feet of snow, complicating emergency response efforts and prompting additional state support.

Cities and towns including Brockton, Taunton, New Bedford and Fall River received outside assistance Thursday as crews continued to plow streets and clear critical infrastructure. While road conditions have improved in many areas, officials said buried fire hydrants remain a serious concern.

NBC10 Boston obtained Taunton police body camera footage that captured first responders scrambling to locate a hydrant during a house fire on Plain Street.

“Looking for a hydrant now,” one first responder can be heard saying. “They’re all buried.”

At one point, an officer asked a bystanders for help.

A home was burned to the ground after an explosion that left two people injured.

Officials said the home exploded after a gas leak Wednesday, leaving a family of three displaced.

The mother and daughter were treated for serious burns.

William Shivers, who helped firefighters dig out a hydrant, described the urgency.

“We took the shovels, and we were just banging into the snow, looking for a fire hydrant,” he said.

After locating a hydrant using a map on his phone, Shivers and firefighters were able to clear it, but he said the delay could have been worse.

Two people are in the hospital and neighbors are worried about safety after an explosion and fire reduced a house to rubble.

“Imagine how many more how many more minutes that would have been wasted, you know, shoveling, just going through the snow,” said Shivers.

The case underscores the broader challenges facing first responders across the region following Monday’s storm.

Firefighters in Watertown also experienced delays accessing hydrants during a fire on Tuesday.

Snow and ice presented challenges as firefighters battled flames Tuesday.

Gov. Maura Healey toured parts of the South Coast on Thursday and said the region was hit especially hard.

“This whole region, I think, was ground zero,” she said.

Healey said the state will continue deploying resources to affected communities.

“We won’t take our foot off the gas at all,” she said.

The governor activated the Massachusetts National Guard. Troops assisted with snow removal in Plymouth, conducted wellness checks in Duxbury and provided medical and logistical support in Fall River.

Matt Medeiros of Fall River was praised by the governor and other officials for developing an app that allows residents to report unplowed streets.

“It’s just hoping to get those resources in and everyone just staying out of the way of trucks and equipment,” he said.

Meanwhile, Mansfield implemented a parking ban at 8 p.m. Thursday to allow plows to clear roads more efficiently.

Matthew Lawlor of WalkUp Roslindale, a nonprofit advocating for clean and safe streets, emphasized that residents also play a role in public safety.

“The fire hydrant piece of it’s essential,” he noted.

Lawlor urged neighbors to clear hydrants near their homes before an emergency strikes, while also calling on elected officials to provide some incentives.

“To the extent that people can be encouraged to dig those hydrants out as soon as they can, so that it’s not waiting until something happens,” he said.

State officials said the blizzard slowed plowing operations, contributing to the lag in sending additional help to some communities. The Massachusetts Department of Transportation said it hopes to deploy its 200 pieces of equipment to impacted areas within the next 24 to 48 hours.
