A Flood Risk Assessment is a technical report that supports your planning application by evaluating the likelihood and potential impact of flooding on a proposed development.

The purpose of a Flood Risk Assessment is to identify flood risk, assess how a development may be affected by flooding and demonstrate that appropriate measures are in place to manage those risks. The assessment also considers whether the proposed development could increase flood risk elsewhere.

A Flood Risk Assessment may be required to support a planning application where a proposed development could be affected by flooding or may increase flood risk elsewhere.

A Flood Risk Assessment is typically required for developments:

• Located within areas identified as being at medium or high risk of river flooding.

• Located within areas identified as being at risk of coastal flooding.

• Located within areas at risk of surface water flooding.

• Proposed on sites where historical flooding has been recorded.

• Located within identified functional floodplains.

• Located within areas where climate change may increase future flood risk.

• Proposed in locations where flooding could affect the safety or operation of the development.

• Required by the Local Planning Authority or relevant statutory consultees, including SEPA.

If you are unsure whether your development requires a Flood Risk Assessment, Raincloud can undertake an initial screening review and provide guidance on the planning requirements for your site.

A Flood Risk Assessment is a site specific technical report that evaluates flood risk and demonstrates how a proposed development can be designed to remain safe throughout its lifetime without increasing flood risk elsewhere.

A flood risk assessment will included the following:

• Review of SEPA flood mapping and data

• Assessment of fluvial, tidal, surface water, reservoir, sewer and artificial sources flood risk.

• Analysis of historical flood records.

• Review of topography and existing drainage.

• Assessment of climate change.

• Application of the sequential and exception test (if required).

• Advice on finish floor levels and safe access/egress.

Every development is unique, which is why we tailor our reports to your specific development requirements in line with Scottish planning policy.

‍ The cost of a Flood Risk Assessment in England varies depending on the size, location and complexity of the proposed development.

Get in touch via our contact form or email hello@raincloud-consulting.co.uk and we will provide a clear and competitive fixed fee quotation with no hidden costs.

At Raincloud, we aim to deliver Flood Risk Assessments significantly faster than the typical 4–6 week industry standard, helping to keep your planning application on track wherever possible.

The overall timescale depends on the complexity of the site and, importantly, the availability of the information required to complete the assessment. This may include obtaining flood risk information and supporting datasets from third parties.

Once all relevant site information and supporting data have been received, our team will complete your Flood Risk Assessment as quickly and efficiently as possible, while ensuring it meets planning authority and SEPA requirements.
