Flood Risk Assessments for UK Planning Applications

Flood Risk Assessment

A Flood Risk Assessment (FRA) considers the potential risk of flooding to and from a proposed development.

Our flood risk consultants prepare assessments for planning applications and development projects across the UK, considering the characteristics of the site, existing flood sources and proposed development.

The assessment can help identify appropriate mitigation and drainage measures and support the planning process.

Flood Risk Assessment for Planning

A Flood Risk Assessment may be required where a proposed development is located within an area at risk of flooding or where the development itself could affect flood risk elsewhere.

Our assessment considers the relevant sources of flood risk and the characteristics of the proposed scheme.

The scope is tailored to the location, development type and planning requirements.

Sources of Flood Risk

Flood risk can arise from a number of sources, including rivers, surface water, groundwater, sewers, reservoirs and other drainage infrastructure.

We assess the relevant sources for each site and consider how they may affect the proposed development.

The assessment can also consider whether the development could increase flood risk elsewhere.

Flood Mitigation and Drainage

Where flood risk is identified, appropriate mitigation measures can be considered as part of the development design.

This may include finished floor levels, flood resilience measures, surface water management and sustainable drainage.

Our flood risk and drainage specialists can coordinate these measures with the wider development proposals.

Flood Risk Reports for Development

Our reports provide clear technical information to support planning applications and development decisions.

We focus on identifying the relevant flood risks, explaining their potential significance and establishing proportionate measures to manage those risks.

Frequently Asked Questions

1 Why is a Flood Risk Assessment (FRA) necessary for UK planning applications?

A Flood Risk Assessment (FRA) is required for UK planning applications to evaluate potential flood risks from various sources, including rivers, surface water, and groundwater. It helps ensure that new developments are safe and do not increase flood risk elsewhere. The assessment also provides advice on appropriate mitigation measures.

2 What types of flood risks are covered in a typical assessment?

A comprehensive flood risk assessment typically covers risks from rivers, surface water (pluvial), groundwater, and existing drainage systems. It identifies potential hazards and their impact on the proposed development, aligning with UK planning requirements.

3 Does the assessment include advice on flood mitigation and drainage strategies like SUDs?

Yes, the assessment provides advice on flood mitigation strategies to protect developments. It also includes expertise in Sustainable Drainage Systems (SUDs) design and broader drainage strategies, along with foul water and utilities assessment, to manage water effectively within the development.
