Sand dredged from offshore is sprayed onto the beach, a process known as rainbowing. This currently costs £20/m3. However, a more efficient method of dredging from the harbour is only £3/m3.
Residential properties per square metre are currently 4th most expensive in the world.
Climate change means that sea levels are predicted to rise here by about 0.6m in the next 100 years. This would not only cause flooding of many properties but could breach the peninsula at its lowest and narrowest point (Only 2m above sea level and 50m wide). This would effectively cut off the end of the peninsula from the mainland.
It is estimated that if no management strategies are applied, £18 million of damage to residential properties would occur in the next 20 years.
