Understanding Flood Risk in Enfield
Flood risk assessment in Enfield reflects its location within the Lee Valley catchment, where flood risk is influenced by the River Lee, tributary watercourses, reservoirs and urban drainage networks.
When do you need a Flood Risk Assessment in Enfield?
FRAs will likely be necessary when there is significant flood risk to a proposed site which is situated in higher flood risk areas. When larger than normal development schemes occur that exceed national threshold criteria, FRAs could also be required.
Common scenarios include:
- Development in Flood Zones 2 or 3: If a site in Enfield is within Flood Zone 2 or Flood Zone 3, an FRA is typically required for the planning submission.
- Sites over a certain size: Even in lower-risk areas, sites in Enfield of 1 hectare (10,000m²) or more often require an FRA as part of the planning application.
- Change of use: A change of use to residential accommodation may trigger the need for an FRA where vulnerability increases.
- Basement extensions: Basement works can require an FRA where groundwater, drainage capacity, or flood resilience needs to be considered.

FAQS
You probably will need a Flood Risk Assessment for any development taking place in either of the two higher risk flood zones (Flood Zones 2 & 3), and/or if you're developing over 1-hectare in size. Similarly, a Flood Risk Assessment will be necessary if you're experiencing surface water flooding or constrained drainage.
Most Enfield planning applications now need to comply with both national flood risk policies, and those set out by Enfield Council regarding drainage.
It would be good to have as much information as possible about your site. This includes architectural drawings, site plans, a topographical survey and details of what you plan to build. If you're just extending an existing property or making changes to something already built, existing drawings are necesary to give us a better understanding of how we can assess flood risks quickly.
Yes. The clearer you are about how you've addressed flood risk through your flood risk assessment, the less likely you'll face planning application objections or validation problems which might slow down your process.
There's always a chance even relatively small extensions may need to undergo a Flood Risk Assessment. If this is the case for your project, it will most likely be because either:
a) Your extension is located inside one of the two higher-risk flood zones; namely Flood Zone 2 or 3.
b) There are specific local drainage or surface water issues associated with where your extension is being built.
Requirements vary depending on whether or not there are restrictions associated with where your extension will be built based upon local policy.
The Enfield Surface Water Management Plan is a local authority document aimed at identifying potential hotspots for surface water flooding throughout the borough. It offers guidance for various stakeholders who develop drainage schemes or other mitigation techniques to reduce flood risk.
