It's estimated the cost of damage caused by this month's severe tidal surge could reach £1million in one part of North Yorkshire.
In a report to councillors, officials at Scarborough Borough Council said urgent repairs are needed to unsafe buildings which pose a risk of death or injury to the public.
The Borough of Scarborough was badly affected with flooding and consequent power outages in Staithes, Sandsend, Scarborough and Whitby. The areas around the harbours in Whitby and Scarborough were particularly badly affected, as were the sea defences outside the Sands apartments in Scarborough.
Teams of staff from North Tyneside Council have been patrolling the local coast ensuring areas affected by the tidal surge were safe.
They have been able to re-open most of Longsands beach, which was initially closed off, owing to concerns over the stability of sand dunes and missing fencing.
Concrete and tarmac is missing from Watts Slope, the area outside the Boardwalk Café in Whitley Bay, making it potentially hazardous.
At High Point, where fencing is missing, workers have made the area safe, since there is a drop of around 20 feet onto the rocks and sea below.
Tynemouth Longsands beach has sustained substantial coastal edge damage with a significant amount of sand gone from the shore. This will be replaced through the natural process of renewal.
There has also been some damage to the caves at Cullercoats Bay. But it does not pose a safety risk.

Residential, commercial and industrial premises in the area are at risk.
Flooding is possible this evening between 4.30pm and 7pm. The high tide is just after 5.30pm. Official advice is as follows:
- Avoid beaches, promenades, coastal footpaths and roads.
- If it is safe to do so, block doors with flood boards or sandbags and cover air bricks and other ventilation holes.
- Move family, pets and valuables to a safe place.
- Keep a flood kit ready including a torch, batteries, fully charged mobile phone, warm clothes, water, food and any prescription medicines you may need.
- If it is safe, make sure your neighbours are aware of the situation and offer help to anyone who may need it.
- Avoid walking, cycling or driving through flood water.
- Turn off gas, electricity and water if your property is about to flood. Never touch an electrical switch if you are standing in water.
