The coxswain at Hemsby Lifeboat has said he would be getting his valuables together if he lived in one of the properties close to the cliff edge at Hemsby, following extensive erosion.
The erosion, caused by high tides and winds, has resulted in losses of up to four feet from the dunes to the North of the Gap and a six-foot sheer drop at the entry to the beach.
Hemsby Lifeboat is unable to launch due to the damage, and has warned of a "threat to the public due to the instability of the sand where the sea has cut into the slope to the beach".
They have put a call out for donations, which will be used for beach renovation and get the lifeboat back to service.
The tide peaked at 2.89 metres at 10.44am on Saturday morning (February 25) and the entrance to the beach is blocked off for safety reasons.
This is the highest it has been for a while and it has caused erosion reaching up to 1.5 metres inland on some parts of the dunes.
Coxswain at Hemsby Lifeboat, Daniel Hurd, told the BBC a woman in one of the properties was leaving and emptying her home, but added the second household had decided to stay and monitor the situation.

He said one of the two bungalows was a foot (0.3m) from the cliff edge, adding: "I would be getting my valuables together if I lived in one of those properties because personally, I wouldn't want to be in there knowing what this sea can do.
"It's devastating for us - we put so much time into our efforts here and it's heartbreaking for us every time we get something like this."
The tide is expected to reach 3.59 metres at 10.45pm tonight (February 25), which could cause further erosion.
In a Facebook post, Hemsby Lifeboat said: "It was deemed too much of a risk to public safety by the lifeboat, and so the decision was taken to temporarily close the access point to the beach to avoid the chance of injury due to further collapse.
"We thank members of the public who have been very supportive of these preventative measures taken by the crew, despite those measures restricting their movements. Mostly, it was understood that these measures were in everyone's best interest despite the inconvenience. There is also some risk of further erosion tonight as the high tide is predicted to be slightly higher tonight, with the wind direction contributing to that risk.
"The crew will be on standby later tonight to assist with any actions that may be required further to minimise the risk to property and the public. We hope this precaution will remain just that, and the beach will be opened again as soon as the area is safe.
"Representatives from various agencies have been informed and have also visited the areas most at risk so that appropriate plans and actions can be implemented if required."
