Flood Update from the EA

The Environment Agency (EA) were there at the Guildhall to give us the latest news on managing the flood risk in Abingdon.

The good news is that they now think that the July 2007 River Ock flood has the probability of happening one year in 275, not one year in 100 as estimated before. This means some properties will be removed from the "high risk flood zone" and "should have fewer problems getting insurance".

The bad news is that it means that the proposed upstream flood storage area has a lower Benefit / Cost ratio, and they now say in yesterday's briefing note "... We are unable to justify a scheme on the River Ock because the flood alleviation works will protect fewer properties..."

Various less costly schemes are still to go ahead. These two pictures show the effect of removing the redundant Ock Mill footbridge during a time of high flood. The bottom one shows that after the removal thirty odd properties, in the pale blue area, at Meadowside, will be safer. The EA model suggests that because the lower stream will not back up so much, the higher stream in front of Meadowside will more easily cascade down the weir.

Here is the Ock Mill footbridge this bright frosty morning. Work to prepare for removing the bridge will start in the week commencing 16th march, and the actual removal start the week after. More pictures to follow.

Other flood risk management work, all around Abingdon and some on the River Stert, will involve: improving culverts, clearing vegetation and blockages, and designing better trash screens.
