Autopsies have shown that at least five of the victims died of hypothermia from exposure to the cold and intoxication was a contributing factor in at least four of the deaths.
"We have made approximately 1400 placements into shelters and safe havens. We have involuntarily transported 33 New Yorkers who were deemed to be a danger to themselves or to others," Mamdani said.
Despite the deaths, the Mayor's response likely saved many more lives, according to David Giffen of the Coalition for the Homeless.
"I've never seen a mayoral administration address a cold snap like this with the kind of creativity and level of effort that we've seen over the past two weeks, and I'm honestly impressed with what they have done," Giffen said.
Giffen credits stepped-up outreach and a vast network of warming centers in schools and buses. But others say the city should be doing more.
"How could you look at her and say the city is doing well? I mean, you say, 'Oh, that's okay, that's all right, stay out here and freeze to death.' I'm sorry," Chelsea resident Kathy Malichio said.
Forcing people indoors is a last resort. And many are resistant to it.
"I've got to stay. I've got to stay out here with the public," one homeless woman said.
Medics arrived in Chelsea after Eyewitness News called 311, but they were turned away when the woman told them she wanted to be left alone and on her own on the city's streets.
"We really look forward to seeing how the administration will apply this kind of energy and creativity that they used when confronting the cold snap to addressing the underlying problems that put people in danger in the first place," Giffen said.
Across New York City, subzero winter weather is still impacting different aspects of city life, from blocked parking spots, sidewalks, and Citi Bike stations to increased social services.
Some Tri-State school districts have announced delayed openings for today because of the weather.
This week, cleanup continues as the weather starts to warm up a little.
The city's sanitation department keeps working to clear and melt accumulated snow and ice around the city, which hasn't melted due to unusually cold temperatures.
Alternate side parking rules are suspended until Tuesday.
Citi Bike believes "the vast majority" of its docking stations will be dug out by the end of the day.
Citi Bikes were buried by snow plowed into their docking stations following the snow. Less than a week ago, only about 500 of the 2,200 active stations, just 22%, were cleaned out.
Despite warnings from officials to stay inside because of the subzero wind chill and potential frostbite, some still prefer to ride a bike:
"I biked all the way back just to have a station where I could put it back in, and then I didn't bike for a few days because it just wasn't worth the trouble... I'm the kind of guy who likes to take chances, take some risks, so I'm ok with it," said Citi Bike rider Nirmesh.
Mayor Mamdani visited a warming center over the weekend, encouraging vulnerable New Yorkers to go to one if they need to.
"This is all the work that city workers are doing in tandem with more than 550 outreach workers who were out there at all times of day to bring homeless New Yorkers inside, to ensure that we're connecting them with safe havens, with shelters, even with hotel rooms, to ensure that no one is outside," Mamdani said.
Residents are urged to call 311 if they see someone in need.
