Flood zones, the coast and protected nature on this street
Flood zones
Part of Marina is in Flood Zone 3 (the sea). That is the Environment Agency’s flood map for planning, which shows land that could flood from rivers or the sea, ignoring the benefits of any existing flood defences.
Locations in flood zone 3 have a high probability of flooding.
This means, in any year, land has:
- a 1% (1 in 100) or more chance of flooding from rivers
- a 0.5% (1 in 200) or more chance of flooding from the sea.
Flood zone 3 developments need a flood risk assessment as part of their planning application.
The coast
The Environment Agency’s erosion map covers this frontage: 3 stretches of policy unit 4C24 Hastings (inc. the Harbour) ↗ in the Shoreline Management Plan, whose policy is Hold the line (Maintain/replace) in all three periods, 2005 to 2105: “Where protection is currently provided by coastal defence structures or managed beaches, and the intention is to retain a defence along approximately the current alignment. This will involve replacing defences when needed. Defence type, method and standard of protection may be modified over time.”
- With Shoreline Management Plans delivered: 0 m by 2055, 0 m by 2105.
- No Future Intervention: 24 to 56 m by 2055, 47 to 99 m by 2105.
All of Marina’s line is inside the map’s No Future Intervention zone to 2105, and none of it inside the zone to 2105 with the plan delivered.
The data and associated information are intended for guidance only - it cannot provide details for individual properties.
The data shows areas of land likely to be at erosion risk but does not show the precise future position of the shoreline.
Erosion may happen faster or slower than what we show, and risk may change over time.
