Residents of the Windsor House residential home, in Acomb, York, were moved to other care homes earlier after the basement flooded. The council spokeswoman said their families had been informed.
The spokeswoman said: "Partners and emergency services are working round the clock in York to tackle unprecedented levels of flooding in the city.
"Provisions are in place across multi-agencies following overwhelming river levels for the Foss and Ouse.
"Front line teams from all organisations are working round the clock to protect residents and tourists."
A number of roads were closed in the area and public transport is affected. People were advised to only drive if necessary.
Environment Secretary Liz Truss told BBC Breakfast that levels of rain have been "unprecedented" and said flood defences will be reviewed.
"We've been preparing with a series of Cobras through the Christmas period, so we've got the Army out working round the clock, as well as the Environment Agency, local authorities, to make sure that we protect lives.
"And today the Prime Minister will be chairing a Cobra to continue that work to make sure that we've got all the resources on the ground that are needed to support families in these truly very, very difficult times," she said.
Asked about how much money was being allocated, Ms Truss said the priority was protecting lives and homes.
"We're still in a situation with major flood warnings, people need to look at the latest advice from the Environment Agency, from the emergency services. That's really important because in many places we have not yet reached the high point. So it's really important that that is the effort over the next few days.
"Of course, you've asked about funding and we're looking at schemes similar to what we put in place in Cumbria to make sure families and businesses are supported.
"We're looking at that at the moment, but my priority is making sure that we have a good response effort, that we give families, communities, all the help they need to make sure we protect lives and we protect people's homes," she said.
Ms Truss said it was "right to say" that flood defences had been "overwhelmed" in Lancashire.
"Every single river was at a record high," she said, adding that in Yorkshire some rivers are a metre higher than they have ever been before.
"And clearly in the light of that we will be reviewing our flood defences," she said.
North Yorkshire Police said they have run out of "road closed" signs, writing in a tweet: "Several calls from people that have driven into floodwater, we have run out of road closed signs, don't enter floodwater, avoid flooded roads."
