Water Levels and Flood Risk

It is strongly recommended that you contact the Environment Agency (EA) to establish their initial considerations, including advice on whether your site is in the flood plain and other water level or drainage issues to consider. This can be done using a Pre-Application Form (see link below) to ensure that all relevant information is available for the EA to assess.

Local Planning Authorities (LPAs) in England have to consult with the EA on most development proposals at risk from flooding. Planning Policy Statement 25 (PPS 25) 'Development and Flood Risk' and its associated Practice Guide set out Government policy and advice on the subject.

LPAs in Wales are advised to consult the EA on development proposals that are at risk from flooding through the Welsh Assembly's Technical Advice Note 15 (TAN 15) 'Development and Flood Risk'.

The EA provide technical advice to LPAs and developers on how best to avoid, manage and reduce the adverse impacts of flooding.

You should also discuss any flooding issues with British Waterways as there may be impacts on canal infrastructure. In addition any surface water discharge into the marina/canal (if permitted) needs a formal agreement with British Waterways, please refer to the link below.
