New plans drawn up to combat A12 flooding at Blythburgh near Southwold
08:12 28 December 2012
WORK to prevent tidal flooding on a stretch of the A12 could begin next summer – if new plans get the go-ahead.
Proposals for a major flood relief scheme at Blythburgh will be unveiled to the public in the next few weeks.
The plans include installing a sluice to stop water flooding the A12 during a tidal surge – as happened in 2007 when the road was closed, causing major disruption to traffic, residents and businesses.
The scheme, backed by the Blyth Estuary Group and local community, is being developed by Suffolk County Council with advice from Natural England and the Environment Agency. It offers an alternative to raising the road level while protecting the estuary flood defences and the recently-completed work on Southwold Harbour.
The new sluice would act as a barrier, stopping tidal water from flowing upstream beyond the bridge but allowing fresh water to pass downstream, and allowing wildlife free passage.
Guy McGregor, county council cabinet member for roads, transport and planning, said: “I am pleased that we are at last making progress in pursuing the sluice option to alleviate the disruption caused by flooding on this major route. This should also protect the vital flood defences to the estuary and Southwold Harbour.
“The support and advice we are receiving from the local community and key agencies is vital to the success of this scheme. However, before anything is finalised, we must satisfy ourselves that this will not have an adverse effect elsewhere. This decision promises to have a hugely beneficial impact for future generations, so it is crucial that we get it right.”
People will soon have the opportunity to view and comment on proposed designs for the sluice option at a series of open events before public consultation starts. Further impact assessments will also be carried out on the potential effect on natural habitats and the flood risk for neighbouring properties.
If permission is granted, and plans are approved, construction work could begin at the end of the summer.
The council said that any construction work would take place between September to December to minimise disruption to traffic using the A12 during the peak summer months and to over-wintering birds, as the nearby estuary is home to many important species.
Sue Allen, who chairs the Blyth Estuary Group, said: “We are delighted that the sluice option is still on the table, and that Natural England and the Environment Agency are working with us. It is what we have asked for, and represents the views of our group on behalf of the community. We will continue to support the scheme through its next stages and very much hope that work can begin next summer.”
