It is also a responsibility of the Highways Authority for the drainage of highways. The Environment Agency is responsible for dealing with coastal flooding and flooding from main rivers.

Flooding is one of London’s highest risks, with up to 680,000 properties across the capital at risk. The Environment Agency’s flood map will show you if you’re at risk of flooding from rivers, tidal or surface water. The DrainLondon project is working with Local Authorities to map areas at risk from surface water flooding.

As a result of defences, most of the tidal floodplain is at low risk; but there are high or medium risks near the Thames.
