Peak river flow climate change allowances by management catchment

Information on peak river flow allowances for flood risk assessments, and flood and coastal risk projects, schemes and strategies.

Flood risk assessments: climate change allowances

When and how local planning authorities, developers and their agents should use climate change allowances in flood risk assessments.

This guidance is for:

• local planning authorities preparing strategic flood risk assessments
• developers and their agents preparing flood risk assessments for planning applications, and development consent orders for nationally significant infrastructure projects

Making allowances for climate change in your flood risk assessment will help minimise vulnerability and provide resilience to flooding and coastal change.

The Environment Agency will check that you have used climate change allowances when they provide advice on flood risk assessments and strategic flood risk assessments.
