Managing flood risk and drainage on developments
The Environment Agency is the leading public body protecting and improving the environment.
You can find guidance on flood risk assessments for developers on GOV.UK.
If your proposal requires a full flood risk assessment, we advise you to discuss the assessment's scope and content with the Environment Agency and our planning team before you start work on it - email: firstname.lastname@example.org.
New developments are encouraged to use sustainable drainage throughout, to reduce the risk of flooding.
Sustainable drainage through planning
Sustainable drainage systems (SuDS) provide alternatives to the direct channelling of surface water through pipe networks and sewers to a nearby watercourse.
It's essential that consideration of sustainable drainage takes place at the start of the design process and the site design is adjusted accordingly. This should ensure the most cost effective, well designed sustainable drainage to deliver the required functionality.
All major planning applications must ensure that sustainable drainage systems for the management of run-off are put in place, unless demonstrated to be inappropriate.
A developer should:
- consider how to use SuDS throughout the green spaces and highways
- contact the Local Lead Flood Authority at the earliest opportunity to discuss the SuDS design, to minimise the risk of later design conflicts
- provide a Sustainable Drainage Assessment and a Sustainable Drainage Operation and Maintenance Plan when you submit a planning application for major development - failure to provide these documents may result in your planning application being invalidated
We work with Peterborough City Council on all SuDS schemes - visit their website for more information on sustainable drainage.
