If the Oxford Flood Alleviation Scheme were in place this wouldn’t be happening

River levels in Oxford remain high this morning, but have now stabilised. Some homes and businesses have flooded in the last two days, and thousands more people in the city have faced a stressful 48hrs as the response services have battled to contain floodwater. If the proposed Oxford Flood Alleviation Scheme were in place today none of this would have been happening. At these kinds of river levels roads would have remained open, properties and businesses would have stayed dry, and local residents would not have had to endure sleepless nights.

Because we don’t have the scheme in place we have to rely on temporary barriers and pumps to keep flood water at bay. Deployment of these defences depends on Environment Agency and Council staff working long hours to erect and maintain them, often in difficult circumstances. For the most part the response has been effective this time, but in South Hinksey the weather conditions on the night of 5 January meant temporary barriers could not be fully erected and low lying areas of the village were inundated. Barriers and pumps are now working and floodwater has been cleared. If OFAS were in place the village would not have gone through this ordeal, and until the scheme is built communities remain vulnerable to temporary defences failing.

Oxford is used to floods having the long slow buildup. This time river levels rose very fast. One question which will need to be looked at when the operational response is evaluated is whether defences were in place early enough in some locations.

OFA believes the big flood scheme is needed now. If proof were still needed of why the scheme is essential, the last few days have provided it.

Speed of recent river level rises concerning

The striking thing about the flooding of the past few days is the speed at which river levels rose following several hours of torrential rain on the evening of Friday 31 March. This resulted in some flood events not previously seen in the county.

Tescos Extra in Abingdon was closed for two days due to a flooded car park, and Oxfordshire Wildlife Rescue suspend its operations after its centre near Didcot flooded on the Friday night. We have had reports of flooding at Sunningwell, north-west of Abingdon, and of flash flooding in Hurst Rise Rd and Hutchcombe Rd in west Oxford. The Eynsham Rd near the junction with the A420 was closed for a while due to flooding.

Botley Park. and the allotments to the east of the park, went from being completely dry on the Saturday afternoon to being flooded 24hrs later. Plot holders were taken by surprise at the speed at which their allotments flooded. At Seacourt P&R, the extension was fully flooded within 24 hrs.

Fortunately the amount of rainfall on Friday was not enough to cause more widespread disruption, but the speed at which rivers rose after just a few hours of heavy rain illustrate how vulnerable we would be in the event of a much bigger storm, and not just those areas known to be at risk from floods.

River levels have now stabilized in Oxford and Abingdon. Further up the Thames levels are either stable or falling.
