Millions needed to shore up prom to protect seaside town from flooding
Millions will need to be spent on shoring up a town's flood defences because of coastal erosion.
West Norfolk Council says test pits dug along Hunstanton Prom have revealed areas of its foundations are now at risk of being undermined.
It is because changing offshore currents which have washed sand and shingle away from the base of the revetment exposing it to the tides.

At a briefing on Thursday (August 7) officials said sheet piling would be needed to prevent "structural failure" along sections of the defences in front of The Oasis, the Rock Shop ramp and North Prom.

Mr Robson said the concrete was 70 years old and in "poor condition" and new panels would need to be installed.

The council hopes it would be funded by the Regional Flooding and Coastal Committee, which allocates flood defence funds provided by central government.

A 10-tonne weight limit and 5mph speed limit will also be brought in along the Prom from September until repairs have been carried out.
A smaller bin lorry has been drafted in to empty bins along the Prom.
