A flood victims’ group is to unveil its second set of proposals to help reduce flooding in Oxford.

The Oxford Flood Alliance will unveil its latest ideas to some of the region’s most influential figures tomorrow, two years after it helped determine where £1.8m of flood alleviation work should be carried out.

In March 2008, the residents’ group put forward a plan to increase waterflow through Redbridge and Kennington south of the city.

The plan won favour with the Environment Agency (EA), which carried out the work as part of its short-term measures, culminating in the installation of three giant new culverts, costing £750,000, in the Hinksey Drain in November.

The alliance is now set to unveil a further 15 suggestions to an audience of more than 20 people, including the chairman of the EA’s regional flood defence committee for the Thames, Amanda Nobbs, and the leader of Oxfordshire County Council, Keith Mitchell.

The alliance believes its proposals will cost less than £10m.

The ideas come three months after the EA revealed its planned £100m flood relief channel west of Oxford was unlikely to get Government approval unless Oxford was hit by more floods.

Alliance member Dr Peter Rawcliffe, of South Hinksey, who has been flooded three times since 2000, said: “A number of people have said to us they think the measures have been working and when we have had heavy rain they said they haven’t seen as much flooding in local fields.

“Flooding is a massively expensive recurring cost and the next time it happens it’s going to cost a massive amount again.

“We need to reduce that.”

At the meeting the alliance will call for two flood-alleviation measures to be carried out urgently.

It wants the Hinksey Drain cleared, desilted and widened where it approaches Munday’s Bridge and Stroud’s Bridge.

It also wants the channel remodelled at Stroud’s Bridge to eliminate a 90-degree bend and to have Stroud’s Bridge widened if further capacity is needed.

The alliance is also urging for the gradient of Lamarsh Road in west Oxford to be lowered to allow flood water to wash away from Duke and Earl Street, past a planned extension of the Botley Road retail park.

EA spokesman Keith Hutchence said: “We have found working with the Oxford Flood Alliance has been very helpful.

“Their suggestions so far have helped increase the capacity of the river system through South Oxford.”
