OFA Update / OFAS & Flood Exercise

This update has recently been sent to those on our mailing list.

Dear OFA contact,

We last sent out an update in Oct 2019, just after the news about the problems with the A423 bridge (southern bypass) and likely delays to the Oxford Flood Alleviation Scheme (OFAS). OFA is still active and has been participating in meetings of the Sponsoring Group for the OFAS scheme and has also held separate meetings with the Environment Agency team about water course maintenance since our last update.

Despite the A423 issues, and the challenges presented by coronavirus, the OFAS scheme continues to progress. The EA and the County Council have agreed a collaborative approach to replacing the A423 bridge and constructing the OFAS scheme. This should save on costs for OFAS, and reduce the level of maintenance required in future.

The EA withdrew the original planning application earlier in the year and is currently revising this to incorporate the new A423 arrangements, and to update the documents on some other aspects of the scheme. Once these are resubmitted to the planning authority the public will have a fresh opportunity to comment on the plans. The EA is continuing to meet with objectors to the scheme with a view to trying to address outstanding areas of public concern.

Because OFAS is now expected to be delivered two years later than originally expected it is important that effective flood response procedures are in place in case a major flood event happens in the next few years. The EA, Fire Brigade and the local Council officials will be holding a practice response on 20 August to test aspects of current procedures. Because of coronavirus these will not involve the pubic.

The text of a recent update from the Environment Agency is pasted below which provides some additional information on OFAS and other matters,

Oxford Scheme update

A423 bridge replacement

Oxfordshire County Council began the propping work on the A423 Kennington Railway Bridge in July.

Replacement of the A423 Bridge has provided an opportunity to design and build the bridge and the flood scheme together. This allows us to reduce disruption during construction and ensure the best use of public money. The updated design will use open channels instead of culverts to allow the flow of floodwater under the bridge. This will provide a better environment for wildlife and requires less maintenance.

The bridge is at the southern end of the scheme and during a flood, water would need to pass underneath it to re-join the River Thames. This capacity needs to be in place before the scheme is constructed to avoid increasing flood risk elsewhere. We also need to have all approvals, including planning permission and our Compulsory Purchase Order secured.

South Hinksey Archaeology

If you’ve been walking near South Hinksey, you may have spotted our contractors on site. We are carrying out archaeology surveys in a field near South Hinksey village to check whether the area is suitable for us to use as the main compound for when we construct the scheme. The archaeology surveys will determine whether there are any historical artefacts in the field. We want to ensure there’s no risk of us damaging any artefacts or remains. Once we have finished the investigations, we will remove our equipment from the site and reinstate the fields.

Kendall Copse Ground Investigations

To complement the new A423 bridge replacement, we are reviewing the design of the scheme around Kendall Copse, near Kennington.

From 10 August, we will be digging trial pits and drilling boreholes to understand the ground conditions beneath the site in order to finalise these designs.

Oxford Flood Incident Exercise

To ensure our flood protection plans are well-tested, the Oxford Flood Alleviation Scheme partners and emergency responders will be practicing their incident response plans on 20 August 2020.

The flood response exercise will consist of:

 •temporary flood barriers in South Hinksey and Bullstake Close

•pumps to remove flood water along Botley Road

Due to the current Government guidance on public gatherings, we won’t be able to invite members of the community to attend. We will be sharing updates on Twitter and Facebook as the exercise progresses. We will also share video footage of the temporary barriers and pumps so you can see our field teams in action.

Managing your flood risk

During the summer months, flood risk might be low on your list of priorities, but Environment Agency officers are thinking about it year-round. Throughout the year our operations staff carry out inspections and clear debris to keep main rivers moving. To report a blockage that could cause flooding call our 24 incident hotline: 0800 80 70 60.

You can also find out what maintenance is planned in your area: environment.data.gov.uk/asset-management/index.html

Our “2016” Annual Public Meeting – in Feb 2017

We hold an Annual Public Meeting, which has been in November up to now. This makes it close to the annual Oxford Area Flood Partnership meeting and the two have increasingly overlapped in content. We decided then that our “2016” meeting would be better held later. It will be on Wednesday 22 February 2017 at 7pm for 7.30. The venue as before, the Demos’ Club on Osney Island, Oxford. We will have speakers from the Environment Agency (on the Oxford Flood Alleviation Scheme), Thames Water (on their sewer survey) and Network Rail (on their track raising, waterway clearance and culvert installation). Everybody is very welcome.

A talk: Oxford and the Thames – a national hotspot for freshwater wildlife

Later this month,  Dr Jeremy Biggs of the Freshwater Habitats Trust will be giving a talk at South Hinksey Village Hall, on Wednesday 29 June at 2pm titled Oxford and the Thames: a national hotspot for freshwater wildlife, in association with the Oxford Flood Alliance.
 
He’ll look at what makes the Oxford area a national hotspot for freshwater wildlife, what problems freshwaters in the area face and what the solutions are. He’ll consider what the impact of the new flood channel could be and how it could help reverse the century-long decline in the areas freshwaters. There is more information at http://freshwaterhabitats.org.uk/news/oxford-and-the-thames-a-national-hotspot/ or in the flyer Oxford and the Thames_talk flyer_Jun16 FINAL.
  

The talk is free and anyone may attend but space is limited so if you think you would like to come along please let Jo Fever at Freshwater Habitats know so we can try and ensure there is space for all: info@freshwaterhabitats.org.uk or phone 01865 595505.

 
 

 

 

Cambridge ‘Moisture in Buildings’ conference

Following an invitation from Steve Hodgson of the Property Care Association, Adrian Porter of OFA spoke at their ‘Moisture in Buildings’ conference in Cambridge on 12 May 2016. Adrian writes:

‘It was interesting to be able to inform the building trade of the direct benefit that their work can have on consumers, from a very personal perspective, and also how they and the insurance industry need to collaborate to enable homeowners to make the right decision on property level protection.

I was pleasantly surprised to find that not only do the PCA acknowledge the need to improve standards across the building sector, but also that their members are hugely passionate about resolving the problems created by poor workmanship once and for all, for each homeowner.’

Natural flood management, climate change and Oxford: a symposium

Oxford Flood Alliance are hosting their Second Flood Symposium this week, in collaboration with the Environmental Change Institute, University of Oxford. The meeting is fully subscribed.

The topic is Natural flood management, climate change and Oxford.
We will publish a summary of the proceedings on this website.

Meeting with senior members of the Environment Agency

8 November 2010

Peter Rawcliffe, representing the Oxford Flood Alliance, met with David Jordan, national Director of Operations at the Environment Agency, John Russon, Head of Operations, Howard Davidson, Regional Director, and Matt Carter and Barry Russell from the local EA area, on a recent visit to Oxford. We were pleased to have such an opportunity.

A wide-ranging discussion included:

A presentation by OFA emphasising the crucial importance of improving things at Munday’s underbridge in north Kennington.

How community flood groups form and become involved (‘the Big Society’) in working with the EA on flooding. The difficulties of establishing such engagement where it does not already exist.

Attitude to risk and particularly how it relates to the Big Scheme (OFRMS) for Oxford. OFA said there was public scepticism about whether the Big Scheme would ever happen and that people would like things done now to remedy obvious deficiencies, making the most of what already exists, even though they together fall short of a 1 in 100 year standard of protection (as is inevitable).

Once such remedial measures were taken, then incremental improvements to existing watercourses, particularly widening Hinksey Stream, working up the floodplain, might be a sensible approach, rather than relying on a possible new grand Western Conveyance which might very well never materialise.

Having said all that, information gathered for the Big Scheme can inform decisions in the meantime and if climate change makes things worse it might then be implemented. We suggested that improvements now should not be put off for fear of jeopardising the value for money of the Big Scheme – because of the very real and widespread doubt as to it ever materialising (even were no improvements made in the meantime).
