Meetings re Lamarsh Road as a flood route

15 October 2010

Brian Durham and Peter Rawcliffe, both of OFA, met David Coates, Planning Director of Kingerlee, at their Lamarsh Road site. We looked at the site and discussed things in the light of OFA’s report on Lamarsh Road, October 2010, which can be downloaded here.

We all three went on to meet Barry Russell and Selena Peters of the Environment Agency and Paul Kirkley of Oxford City Environmental Development.

Selena Peters presented the results of computer modelling of flood flows, now extended from 1 in 25 year flood levels to 1 in 50: even at 1 in 50, when defences are overtopped at Bullstake Close and Earl Street, the model suggests there is no further benefit to Earl or Duke Streets from relieving any dam effect at Lamarsh Road by lowering it (but see below).

Brian Durham of the Alliance spoke about the important findings described in his report, including those discovered by talking to Jewsons and the Army Surplus shop in Lamarsh Road.

Paul Kirkley (City) gave further information about various matters, including that culvert pipes from an adjacent site obstruct a drain beyond the far end of the Kingerlee site.

David Coates (Kingerlee) suggested how to move things forward, including that S106 moneys payable by Kingerlee and allocated for “art” could perhaps be made available for flood defences instead. This would be in addition to sums that Kingerlee is already contributing. OFA strongly supported this suggestion.

There is now a much better understanding of what might be useful; Brian Durham has shown that “less will be enough”, and it looks more likely to be affordable. In a nutshell, a limited lowering of about 8 cm at the south end to the west would bring significant benefit. The County have apparently agreed to do about 5 cm in an even smaller area, the hope now is to increase that.

The plan agreed at the meeting is that the EA will, with Paul Kirkley, produce specific proposals as to what is ‘required’. That they will then engage with the County road people to obtain as specific and detailed costings as are possible at this stage (unknowns e.g. services may make it less than exact).

Funding might include use of the £25,000 that Kingerlee has contributed, a similar amount (?£20K) that Rewley Press developers are putting in. The possible reallocation of the “art” funding is mentioned above.

Whether Earl and Duke Streets will be helped depends on how reliable the model proves in practice, but the proposed work in Lamarsh Road cannot make them worse. Previously flooded properties in Lamarsh Road will benefit. Kingerlee’s site, Oriel Mews and the Rewley Press residential development will benefit from improved vehicular and pedestrian access during floods.
