What does the 'build back better' principle specifically require for new infrastructure in a flood-affected area, beyond simply repairing to pre-flood conditions?

The 'build back better' principle specifically requires new infrastructure in a flood-affected area to be reconstructed or improved in a way that actively reduces future disaster risks and enhances resilience, rather than merely restoring it to its previous, often vulnerable, pre-flood condition. This means going beyond simple repair to incorporate forward-looking risk reduction measures. Specifically, it requires: Firstly, an updated and comprehensive risk assessment that considers not only historical flood data but also projections for future flood risks, including the anticipated impacts of climate change such as increased rainfall intensity, sea-level rise, and more frequent extreme weather events. This means designing for a future flood scenario that is likely to be worse than past events. Secondly, the adoption of enhanced design standards and building codes. New infrastructure must be built to higher specifications that can withstand these projected future flood levels and forces. For example, this might involve requiring critical....
