Residential Layout, Drainage and Planning Coordination
Design issues that can affect the assessment
Finished floor levels, developable layout, floodplain effects, safe routes, resistance or resilience measures and surface water management can affect the FRA scope and recommendations.
When further work may be needed
Separate drainage strategies, SuDS design, hydraulic modelling, Sequential Test or Exception Test work may be required. The Flood risk and coastal change Planning Practice Guidance sets out the relevant planning framework.
Information Needed to Quote and Start
- Site address and red-line boundary, to review the planning and flood context
- Dwelling numbers, development description and planning stage, to define the assessment scope
- Available site, layout, floor-level and topographical drawings, to review the proposed design
- Drainage records, flood information and authority correspondence, to identify existing evidence and gaps
RIDA can review the information available before confirming scope. See the main flood risk assessment cost factors, or check the long-term flood risk for an area using the official service.
Residential Development FRA FAQs
Do I need a flood risk assessment for a housing development?
The requirement is set by the site’s flood zone, area, development vulnerability, other flood sources and local planning policy. RIDA can review your site and planning information before confirming the required scope.
Can RIDA work from existing drawings and flood data?
Yes. Existing plans, surveys, flood data and drainage records can form the starting point. RIDA will identify missing information that affects the assessment.
What affects the cost and programme?
Key factors include site size, flood sources, available data, design maturity, topographical information and any need for drainage design, surveys or hydraulic modelling.
Can RIDA help address planning-consultee comments?
Yes. Send the decision notice or comments from the local planning authority, Environment Agency or LLFA. RIDA will review the points raised and define any technical response or further work.
