Maps: Environment Agency

Volume 482: debated on Tuesday 11 November 2008

To ask the Secretary of State for Environment, Food and Rural Affairs what criteria the Environment Agency uses to prioritise areas for preparing flooding maps with light detection and ranging technology. (231310)

By March 2011 the Environment Agency will have increased its coverage of digital terrain data. This will provide an accurate, cost-effective model of terrain suitable for assessing flood risk in areas having between a 1 per cent. and 0.1 per cent. annual probability of fluvial flooding, or between a 0.5 per cent. and 0.1 per cent. annual probability of tidal flooding in any year.

The Environment Agency has developed a three-year programme to obtain this level of coverage starting with the areas identified by Catchment Flood Management Plans, Shoreline Management Plans and National Flood Risk Assessment as at highest risk.
