Floods: Motorways

Volume 487: debated on Wednesday 4 February 2009

To ask the Secretary of State for Environment, Food and Rural Affairs with reference to the Answer of 14 July 2008, Official Report, columns 29-30W, on floods, which stretches of motorway have a significant flood risk probability according to the Environment Agency’s flood vulnerability database. (252491)

The flood vulnerability database draws heavily on information held by other parties, and provides a summary of vulnerability to flooding in each 100 metres of land in England and Wales.

Information on motorways at risk of flooding was provided by publicly available ordinance survey data. However to geographically identify and describe each section of motorway at significant flood risk would incur disproportionate cost.

In response to the floods of 2007 and Sir Michael Pitt’s recommendations the Highways Agency has been investigating the resilience of the strategic road network to flooding. The Highways Agency is currently reviewing the Environment Agency’s fluvial flood risk maps and information on ‘Areas Susceptible to Surface Water Flooding’ to identify vulnerable locations and develop appropriate contingency measures. This work is ongoing.
