Boscastle to get £4.6M flood defence project

A £4.6M project to protect the Cornish fishing village of Boscastle from future flash flooding begins next month.

Contractor Carillion will be carrying out the work to lower and widen the River Valency which passes through the village

Boscastle suffered extensive damage in 2004 (NCE 2 September 2004) when heavy rain swept up trees, mud and cars and deposited them in the Valency causing the river to burst its banks.Last week, North Cornwall District Council granted planning permission for flood defences to be built in three locations along the river (see diagram).'The work will be a combination of excavating through bedrock to create a lower channel and raising walls,' Environment Agency flood risk manager Gordon Trapmore told NCE.He added that the Valency would be reshaped in some locations to slow down the flow of during heavy rain. The Agency is also looking at curbing vegetation growth along the Valency where flash floods could cause trees and bushes to be swept up.The proposed work is the result of analysis of computer models, video footage and flood simulations by consultant HR Wallingford.The work will involve raising the level of the main carpark and installing barriers to prevent vehicles being swept up during flash floods, the river to be widened and lowered to increase capacity to carry high flows and the main roadbridge in the village to be rebuilt further downstream.During the 2004 floods, vehicles and debris became lodged under the bridge and caused water to back up in the village.ruby.kitching@emap.com
