Flood and coastal risk products: submit an evidence review request
Summary
The Environment Agency has set out how users can submit an Evidence Review Request (ERR) where they disagree with national flood and coastal erosion risk information shown for a location. The guidance explains the types of evidence accepted, notes that different standards apply to Flood Risk Assessments and ERRs, and directs planning-related modelling queries to the Agency’s planning advice service or the relevant lead local flood authority for some surface water datasets.
Why it matters
Flood risk mapping and related evidence can affect residential site appraisals, planning submissions and valuation assumptions. Surveyors may need to understand the ERR process when reviewing flood data, advising clients, or challenging mapped risk information.
Key points
- ERRs can be submitted to challenge national flood and coastal erosion risk products.
- Evidence must meet the Environment Agency’s technical standards and be based on accepted sources.
- Surface water risk changes for certain datasets must be taken to the lead local flood authority.
- Flood Risk Assessment modelling requirements are different from ERR requirements.
- Planning-related modelling may be handled through the Environment Agency’s charged planning advice service.
