Flood Risk Assessment for Commercial Development
Planning Evidence for Commercial Development
Our assessment will demonstrate whether your development is viable within the relevant flood zones. You will receive clear, practical and timely advice on your proposal, including any flood risk constraints that could affect its viability. Our flood risk assessments for planning permission address the requirements of the NPPF and relevant local planning policy, helping you understand what is required to support your planning application.

Commercial Flood Risk Assessment FAQs
When is a flood risk assessment needed for a commercial development?
Common triggers include the site’s flood zone, site area, known flood sources, a planning policy requirement or a request from the planning authority or consultee. RIDA can review your site and planning context to confirm the likely scope.
What information do you need to quote for a commercial FRA?
Send the site location or plan, proposed use, available drawings and levels, planning reference or authority request, known flood information and target date. These details allow RIDA to define the assessment and any related technical work.
What will the report include, and when might drainage work be needed?
The report will assess relevant flood sources, planning data, commercial use, access, climate change and mitigation. Drainage or SuDS work may be needed where runoff management forms part of the planning evidence or site design.
Can RIDA work from existing drawings and respond to planning or consultee comments?
Yes. RIDA can review existing drawings, technical records and consultee comments, then identify gaps and prepare the appropriate response. Further survey or modelling will be identified before extra work is commissioned.
