The district of north Norfolk has a coastal frontage of approximately 68km stretching from Holkham in the west to Horsey in the south-east.
The central 34km of the coastal frontage, from Kelling Hard through to Cart Gap, Happisburgh, is characterised by soft glacial cliffs and sandy beaches.
This is in stark contrast to the low lying areas found on either flank. In the west there are saltmarshes and the famous shingle ridge leading to Blakeney Point spit, while to the east the beaches and sand-dunes are all that separates the North Sea from the Norfolk Broads.
Coast Management short films
The following short films have been produced to give an introduction to our coastline and the work going into protection and adaptation in the area.

Along the north Norfolk coastline the cliffs are susceptible to coastal erosion. The prevention of coastal erosion is termed coast protection and is provided by Maritime District Councils such as North Norfolk District Council (NNDC).
The council is responsible for both constructing and maintaining the defences on its frontage, as set out in the Shoreline Management Plans. The Department for Environment, Food and Rural Affairs (Defra) also provide some funding for coast protection works.
The north Norfolk cliffs
These are basically comprised of a contorted mix of silts, sands, clays and gravels that were deposited during the glacial and interglacial phases of the last 2 million years.
The cliffs provide little resistance to the aggressive action of North Sea waves, which erode the base of the cliffs.
In addition, when the cliff material has a high water content it becomes unstable and, together with wave action, this results in slips & slides of large amounts of material along the coastline, leading to a general retreat of the cliff line.
The Environment Agency manages flood defences to reduce the risk of coastal flooding and implements flood warning systems when there is a heightened possibility of flooding.
For further information on flood defences and flooding issues please visit Environment Agency flood information page and our own emergency planning flood information page.

- Cromer to Winterton Ness Coastal Management Non Technical Study 2013 - Is a key action from the Kelling to Lowestoft Shoreline Management Plan (SMP6) which sets out the coastal management policies for that stretch of coast. The technical study improves our understanding of how the coast may change, assists in identifying future coast protection schemes and improves our understanding of the level of resources required to manage our coast for the future.

The cost of the work undertaken for this scheme was approximately £1.34 million pounds while the total cost of the works, scheme design and associated expenses was about £1.75 million.

- Cromer Coastal Defence Strategy Study 2003 - Provides a framework for the sustainable management of the coastal defences that extend across the Cromer frontage. The Strategy identifies opportunities and constraints for coastal management over the next 50 years, as well as a more detailed Coastal Defence Implementation Plan for the next 2 years.
Coastal information - advanced level
Large scale studies into coastal defence policies and projects, including sediment transport studies, investigations into management of coastal defences and sustainability of ‘hold the line / do nothing’ policies.
Cromer to Winterton Ness Coastal Management Study 2013
The Cromer to Winterton Study is a key action from the Kelling to Lowestoft Shoreline Management Plan (SMP6) which sets out the coastal management policies for that stretch of coast. This technical study improves our understanding of how the coast may change, assists in identifying future coast protection schemes and improves our understanding of the level of resources required to manage our coast for the future.

The Bacton, Walcott and Ostend report was completed following the Cromer to Winterton Ness Coastal Management Strategy Study. NNDC appointed Mott MacDonald to undertake a further more detailed investigation into the economic case for coastal protection scheme(s) specifically at Bacton, Walcott and Ostend.
The Kelling to Cromer Coastal Defence Strategy Study provides a framework for the sustainable management of the coastal defences of this section of coastal frontage.
Overstrand to Walcott Strategy Study 2002 to 2005
Investigates the sustainability of a selective 'Hold the Line' / 'Do Nothing' management policy, for this section of coastal frontage.
