Do minimum: Rebuild sections of
the seawall as and when they fail,
reconstruct seawall in year 10

Maintain the integrity of the defences with the minimum capital expenditure (repair on failure).

• minimum capital expenditure

• Promenade becomes progressively unusable over 10 years as its collapse becomes inevitable
• No beach
• Risk of failure of the seawall during a storm event, possibly leading to the exposure of the sewerage works immediately behind the seawall structure
• Beach material lost alongshore and offshore
