Diagram: Coastal flood: four measures and the risk each reduces. Labels: Coastal flood: four measures and the risk each reduces | Coastal flood: four measures and the risk each reduces | 1 · Risk-informed land use | Keep new critical facilities outside mapped | surge / flood areas. | 2 · Drainage and protection | Maintain outfalls; use assessed engineered | protection where suitable. | 3 · Shelter and safe access | Provide accessible safe shelters and routes | outside the hazard. | 4 · Warning and evacuation | Send clear alerts and move people before | routes become unsafe. | flood zone | safe | water | safe route | official alert | act early | Transport + assistance + headcounts | Each measure reduces a different part of risk; none guarantees zero flooding. | Protection may overtop; drainage can back up when coastal water is high.

1. Risk-informed coastal land use. Use surge and flood maps to control exposed development and locate critical infrastructure safely. Protect mangroves and appropriate coastal vegetation as part of a wider protection system, not a guaranteed barrier against every surge.
2. Drainage and protective works. Maintain drains and outfalls and use engineered embankments, sea walls or detention where justified by local studies. Consider overtopping, erosion and downstream effects; combine works with warning and evacuation.
3. Shelters and evacuation access. Provide accessible shelters outside surge and flood zones, linked by reliable routes. Practise transport, headcounts and support for people needing assistance so that shelter capacity becomes usable protection.
4. Warning and last-mile communication. Use official forecasts, clear action messages and several communication channels. A forecast must reach fishers, visitors and people without smartphones, with enough time and support to act.
