Flood Risk Assessment Planning Appeal
Technical Flood Risk Evidence for a Planning Appeal
Flood Risk Assessment Planning Appeal is the work that starts with the refusal reason, officer report, consultee responses and evidence already submitted. RIDA identifies the technical gaps and confirms whether the response should be a revised FRA, addendum, technical note, drainage revision or modelling scope. General application-stage requirements are covered by our flood risk assessments for planning permission.

| Technical deliverable | What this enables you to progress |
|---|---|
| Appeal evidence review | Identifies refusal grounds, evidence gaps and proportionate next steps. |
| Revised FRA, addendum or technical note | Provides a focused technical package for consideration by your appeal team. |
| Response to defined flood-risk objections | Addresses relevant mapping, levels, climate allowances, access, residual risk or consultee comments. |
| Drainage evidence, calculations or modelling scope | Progresses the drainage or hydraulic workstream where it is material to the appeal. |
What We Review and How We Scope the Response
- Decision notice, officer report and stated reasons for refusal
- Submitted FRA, flood-zone evidence and consultee comments
- Climate-change allowances, site levels, finished-floor levels, safe access and residual risk
- Surface-water drainage, calculations, SuDS proposals and hydraulic modelling
The review may check the Environment Agency Flood Map for Planning and the current Flood risk and coastal change Planning Practice Guidance. Project evidence may raise Sequential Test requirements, wider flood-risk planning guidance or a need for revised drainage strategies.
Correcting, clarifying or rebutting the technical case
Some objections can be addressed through clearer evidence or corrected calculations. Others require design changes, new data or modelling. RIDA will state if the available evidence does not support the proposed response. Any new material must be considered in relation to the applicable appeal procedure.

What to send
- Decision notice and officer report — to identify the exact refusal grounds.
- Submitted FRA and consultee responses — to assess technical gaps and disputed points.
- Site plans, proposed drawings and drainage information — to check the development and available design evidence.
- Appeal timetable and correspondence — to assess the programme and coordination requirements.
Timing and cost
Programme and price reflect the appeal deadline, evidence gaps, data availability, design revisions, modelling needs and third-party input. A document review or focused note carries a different scope from a revised FRA or modelling exercise. See broader flood risk assessment costs; your appeal quote will define the agreed output and programme.
Planning Appeal Flood-Risk FAQs
Can a revised flood risk assessment support a planning appeal?
Yes, where the revised assessment addresses the refusal grounds and fits the applicable appeal procedure. The review may identify a more focused addendum or technical note instead.
What documents do you need to review a flood-risk reason for refusal?
Send the decision notice, officer report, consultee comments, submitted FRA, site plans, proposed drawings, drainage documents and appeal timetable.
Will RIDA respond to Environment Agency or lead local flood authority objections?
RIDA can review the objection and prepare a project-specific technical response where the evidence supports one. Regulator agreement cannot be assured.
How much does flood-risk appeal evidence cost and how long can it take?
The quote and programme reflect the required deliverable, appeal deadline, available data, design changes and any modelling or drainage calculations.
