How fast is the coast eroding at Sidmouth?
On the fastest-receding frontage within about 1.5 km of Sidmouth (Devon), the Environment Agency's NCERM 2024 projections show up to 25 m of coastline loss by 2055 and up to 93 m by 2105 if defences are not maintained. These figures describe the frontage, not any single property.
Will sea defences protect Sidmouth?
With the planned shoreline management delivered, the projected recession on that same frontage falls to about 81 m by 2105. Whether plans are funded and maintained is the key uncertainty; the local Shoreline Management Plan sets the policy.
