Flood Risk Assessment requirements for development near reservoirs
Applications for built development in flood inundation areas must include a Flood Risk Assessment evaluating downstream flood risk under various scenarios, with measures to manage identified risks and emergency evacuation procedures.
Applications for built development in these areas must also be accompanied by a FRA which demonstrates an assessment of the downstream flood risk in various scenarios (for example, controlled release of water, uncontrolled release due to reservoir failure, change in flow paths as a result of the proposed development). The FRA will also need to set out suitable measures to manage and mitigate the identified flood risks, including details of emergency evacuation procedures.
