§ Mr. Gordon PrenticeTo ask the Minister of State, Lord Chancellor's Department what estimate he has made of the date by which the Thames Barrier will no longer fulfil its primary function; and if he will make a statement. [68053]
§ Mr. MorleyI have been asked to reply.
The Thames Barrier is a robust and flexible installation with a design based on rates of sea level rise predicted in the 1970s which were higher than those currently anticipated. It provides London with a high level of protection from tidal flooding and with normal care and maintenance should continue to do so until at least the latter part of the next century. Even then, although the barrier may need to be closed more frequently it will continue to fulfil its primary function.
The Environment Agency is currently considering the wider long-term flood defence needs of London in consultation with interested parties.
