Some parts of the Manchester may suffer from flood risk i.e. potential inundation from flood waters from either rivers and water courses.
The Environment Agency has identified these areas and maps showing the different zones, categorised according to the degree of risk of flood are available from the Environment Agency website.
Applications for development within these areas may have to be accompanied by a flood risk assessment carried out by the developer before they can be registered.
General advice on how the planning system handles development in relation to flood risk is contained in the Department of Communities and Local Government's publication, Planning Policy Statement 25 'Development and Flood Risk'.
