Project summary

Edit project overview to modify the project summary.


The North Norfolk coast has a high landscape, biodiversity and geodiversity value, with a range of statutory designations. The risk of saline flooding to farmland, freshwater/wet grassland conservation sites and property and infrastructure is managed through a suite of measures including seawalls and natural barriers. A series of schemes have been developed in the past 15 years driven by the Shoreline Management Plan and other initiatives that work with natural processes. Between 2002 and 2015 a series of projects have restored more natural function to around 8km (18%) of the North Norfolk coast (Map 1). These locations showed good resilience to the 2013 storm surge. For example, the now naturally functioning shingle ridge at Cley, although breached in the event, closed naturally within weeks despite initial concerns that it would need artificial manipulation.
