This document gives details about how the flood risk maps for surface water were created and explains the levels of flood risk. Surface water flooding happens when rainwater does not drain away through the normal drainage systems or soak into the ground, but lies on or flows over the ground instead.

Managing the risk of flooding from surface water is the responsibility of lead local flood authorities.

Lead local flood authorities are the unitary authority or if there is no unitary authority, the county council for the area. They work in partnership with other organisations, including the Environment Agency, district councils, water and sewerage companies to manage local flood risks.

The risk of flooding from surface water map was produced by the Environment Agency on behalf of government, using information and input from lead local flood authorities.

You can also find out if you’re at risk of flooding from rivers and the sea and reservoirs.
