Why Do I need a Flood Risk Assessment?
A Flood Risk Assessment (FRA) is generally required when a proposed development falls in a flood-sensitive area (Flood Zone 2 or 3), or involves sensitive uses, basements, or changes in surface water run-off. It demonstrates to regulators that you understand and manage flood risk appropriately.
The Environment Agency provides guidance on what should be included in an FRA depending on the size, location and vulnerability of the proposed development. You can check if your site is in a flood risk area using the government’s Flood Map for Planning.
The LLFA are statutory consultees for all new major developments (10 dwellings or more). They are responsible for managing local flood risks from surface water, groundwater and ordinary watercourses, and ensuring that SuDS proposals meet the requirements of the National Planning Policy Framework (NPPF).
When is a Flood Risk Assessment required?
As a minimum, the National Planning Policy Framework (NPPF) requires an FRA to be submitted:
-
With all applications for sites in Flood Zone 2 (medium probability) or Flood Zone 3 (high probability)
-
For developments of 1 hectare or more in Flood Zone 1
-
For sites under 1 hectare in Flood Zone 1 where there is a known risk or history of flooding from other sources (surface water, groundwater, critical drainage areas, or local flood risk zones)
-
For all major planning applications (10 dwellings or more)
Submitting a robust FRA early in the planning process reduces the risk of objections, delays, or costly redesign. It also ensures that proposed flood mitigation and drainage measures align with national policy and local planning requirements.
