Flood Risk Assessments in Leeds
Flood Risk Environmental provides Flood Risk Assessments, SuDS drainage strategies and detailed drainage design for planning applications across Leeds and the wider West Yorkshire region.
Leeds has significant fluvial flood risk from the River Aire, with major flooding events in 2015 and 2017 leading to significant investment in flood defences and heightened LLFA scrutiny. Many parts of the city centre and riverside areas are in Flood Zone 3. Leeds City Council has detailed SuDS requirements and a well-established pre-application process for flood risk.
Our reports are prepared by a qualified consultant with over 17 years' experience and written specifically to satisfy the requirements of Leeds City Council as the Lead Local Flood Authority and your local planning authority.

When Do You Need a Flood Risk Assessment in Leeds?
Planning applications in Leeds 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 Leeds — 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 Leeds City 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 Leeds 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 Leeds typically requires a new Flood Risk Assessment to confirm future occupiers will be safe.
