Flood Zone
Flood Zone categories are areas within the fluvial floodplain defined by the NPPF based on their probability (low, medium, and high) of river or sea flooding. Speak with a consultant to understand what your zone means for planning. Full flood zone definitions are published in the GOV.UK flood zone assessment guidance.
Case Example
If you are planning to build, the first thing you need to know is whether you are in a flood zone and what the flood risks are, so that you can determine the necessary planning requirements.
Know your flood zone early. Rida Reports defines constraints within your Flood Risk Assessment.
