Cambridge has significant fluvial flood risk from the River Cam and its tributaries, with many riverside areas of the city in Flood Zone 2 and 3. The wider Cambridgeshire area is one of the most active planning markets in the East of England, with a significant growth agenda around the city.

When Do You Need a Flood Risk Assessment in Cambridge?
Planning applications in Cambridge require a Flood Risk Assessment in the following circumstances:
Development in Flood Zone 2 or 3
Any development in London's Flood Zone 2 or 3 areas requires an FRA. The LLFA will object to applications in flood risk areas without a robust FRA and drainage strategy.
Major Applications (10+ dwellings)
Major planning applications in Cambridge — 10 or more dwellings, sites over 0.5ha, or non-residential floorspace over 1,000m² — require an FRA in any flood zone.
Sites Over 1 Hectare in FZ1
Large sites in Flood Zone 1 may require an FRA if over 1 hectare, to demonstrate that drainage is adequate and runoff won't increase downstream flood risk.
LLFA Drainage Conditions
Where Cambridgeshire County Council has imposed a pre-commencement drainage condition, we prepare the detailed SuDS design package needed to satisfy the condition and secure approval.
LLFA Drainage Objections
If your Cambridge planning application has received a flood risk or drainage objection from the LLFA, we can review it and prepare a technical response to resolve it fast.
Change of Use
Converting commercial buildings to residential use in a flood risk area in Cambridge typically requires a new Flood Risk Assessment to confirm future occupiers will be safe.
