Plan for changes in the risk landscape

Infrastructure and planned development will alter the risk landscape. Future floods will bring new surprises as water flows into different places, affecting different communities and infrastructure. Planning for this uncertainty should include: • Placing major assets (critical infrastructure, houses) outside of known floodways and flood- prone areas. • Keeping floodways natural. • Incorporating safe-failure elements in design to avoid impacts that can spread and prove catastrophic. For example, dams should be regularly assessed for flood risk to downstream and surrounding communities. • Building redundancy into infrastructure so key services are not compromised by the failure of individual elements. For example, having more than one way to access clean water. • Using a multi-hazard approach where possible to ensure that increased resilience to one hazard doesn’t undermine resilience to another hazard.
