The Environment Agency commissioned a report for the first time in 2007 to map and improve its understanding of flood vulnerability of infrastructure at a national scale. The resulting Receptors Vulnerable to Flooding database, which draws heavily on information in the public domain and held by other parties, provides a summary of the vulnerability to flooding of various types of public utility infrastructure.
The Environment Agency is currently working on updating this information for publication in spring 2009. The following table sets out a summary of the Receptors Vulnerable to Flooding database 2007.
Number of sites in flood zone (flood risk probability) Asset Significant (1 in 75) Moderate (1 in 75-200) Low (1 in 200 or fewer) Total in all three zones Water and sewerage (Number) 737 223 179 1,145 Electricity, generation and distribution (Number) 2,215 2,263 3,818 8,423 Gas, works and distribution (Number) 5 8 10 23 Telephone exchanges (Number) 82 67 86 241 Motorways (km) 139 104 132 382 A roads (km) 884 553 809 2,278 Railway lines (km) 1,470 750 948 3,213 1 Information extracted from the Environment Agency Receptors Vulnerable to Flooding Database 2007.
This information was originally provided to the Pitt Review team but has since been updated because of changes in the methodology used to collate the data. The Cabinet Office (through the newly recruited Natural Hazards team) will take forward this work with the Environment Agency and other organisations as part of the Government’s action plan in response to Sir Michael Pitt’s recommendations.
We expect to publish the draft Bill in late spring 2009 for pre-legislative scrutiny and public consultation. The final Bill will then be available for introduction in a later parliamentary Session.
The Environment Agency's Floodline Warnings Direct is a free service that provides flood warnings direct to customers by telephone, mobile, email, SMS text message and fax.
The Environment Agency has signed up a further estimated 100,000 customers since July 2007, increasing the number of registered customers from 328,767 to the current 433,314.
