Flood Risk Assessment Surrey
Site-Specific Flood Risk Assessments for Surrey Planning Applications
An FRA for Surrey LLFA may be needed for development in Flood Zones 2 or 3, some Flood Zone 1 proposals, sites affected by other flood sources, or applications where the LPA requests evidence. Read about flood risk assessments for planning permission. RIDA’s flood risk consultants scope the report against your site, proposal and planning context.

Technical deliverables
| Deliverable | Purpose |
|---|---|
| Site-specific flood risk assessment report | Supports your planning application, pre-application response or request for flood risk evidence. |
| Review of mapping, local policy and available site information | Identifies the flood sources and planning matters relevant to your site. |
| Assessment of risk, climate change, access and mitigation where applicable | Provides reasoned recommendations for your design and submission. |
| Advice on further technical work | Identifies any need for drainage, SuDS, testing or hydraulic modelling. |
What this helps you progress
The report gives your project team a defined flood risk evidence package. It does not guarantee planning permission or acceptance by an authority.
Surrey Flood Risk and Planning Considerations
Surrey borough and district planning authorities determine planning applications. Surrey County Council carries Lead Local Flood Authority responsibilities. The evidence needed reflects the proposal, local policy, the relevant SFRA and the site’s flood sources.
The assessment may cover fluvial, surface water, groundwater, sewer, reservoir and residual risk. Local watercourses can include the Thames, Wey, Mole, Blackwater and Bourne, subject to site location.
Planning requirements are set out in the Flood risk and coastal change Planning Practice Guidance. Use the official Environment Agency Flood Map for Planning or RIDA’s Flood Map for Planning for initial Flood Zone evidence. You can check the long-term flood risk for an area across several flood sources. Mapping informs the scope but does not replace a site-specific FRA.
What We Need to Scope Your Assessment
- Site address or postcode, to review the site-specific flood and planning context.
- Development description, to define the assessment scope.
- Drawings and site levels, to assess the proposed layout and levels.
- Planning reference or correspondence, to review any LPA or consultee request.
- Available flood, drainage or ground information, to identify existing evidence.
RIDA will confirm if the project needs drainage strategies, SuDS work, a Sequential Test, an Exception Test, groundwater assessment or hydraulic modelling.
