Work to start on Seacourt P&R

Work begins soon on Seacourt P&R extension, which we opposed fiercely.

Flood scheme and bridges

There’s an article in the Oxford Mail on the new bridges proposed as part of the Oxford Flood Alleviation Scheme at Willow Walk and North Hinksey Causeway. We agree with the Oxford Preservation Trust that it’s very important to get these right – with materials and design appropriate for these much-loved and ancient settings.

Note too that Oxford Preservation Trust is hosting a meeting to discuss plans for the channel at The Fishes, North Hinksey, on Thursday, May 31, from 6.30pm to 8pm. At least one of us plans to be there.

Representatives of OFA will be meeting with City Council officers and their consultants this afternoon to discuss our continuing serious concerns over the (now approved) Seacourt P&R extension. Cllr Colin Cook will also be there as will a representative for Layla Moran MP who is unable to attend in person: both strongly opposed the application.

Weirs Mill Stream obstructed

We’re supporting John Burbank (manager of the Weirs Orchard residential moorings) in his determined efforts, for safety reasons, to get clearance of obstructions above Weirs Mill Stream in the Thames navigation channel by Long Bridges, particularly the trees in the photograph, above Donnington Bridge. We’ve written more than once to the Environment Agency (EA), most recently a few days ago, because we believe that obstructions of this degree, taken together, increase flood risk. John’s concern is primarily with safe navigation where the problem is obvious.

While the EA could clear this they are very probably not obliged to do so, the responsibility is likely to rest with the riparian owner on each bank – but we hope that if the EA don’t do the work themselves they will use their powers to ensure that these trees are cleared as soon as possible.

Seacourt P&R extension site flooded

The site of the planned extension to Seacourt park and ride has been partially flooded for several days, today being the worst so far.

 

Secretary of State on Seacourt

Re Seacourt P&R extension application, we were informed on 9 March as follows:

“The Government remains committed to giving more power to councils and communities to make their own decisions on planning issues, and believe that planning decisions should be made at the local level wherever possible.  The call-in policy makes it clear that the power to call in a case will only be used very selectively. The Secretary of State has decided, having had regard to this policy, not to call in this application.  He is satisfied that the application should be determined at a local level.”

The Secretary of State in question is the Secretary of State for Communities and Local Government, Sajid Javid. Of course his decision is disappointing to us.  The Secretary of State in 1998/99 did call-in, and refuse, a very similar application on the same site. The guidance on not building in the flood plain has become much tighter since then, following Sir Michael Pitt’s report on the nation-wide floods of July 2007. The permission that Oxford City Council has given itself is contrary to both national (NPPF) and local planning policy.  Note that the Secretary of State has not in any sense approved the plans, he has merely not intervened, leaving the decision to the local council.

We believe the Council has pushed through a perverse decision, contrary to planning guidance and a very great deal of substantial and principled opposition from local residents and local organisations. We believe that the Council may come to regret its decision. We will continue to make that case.

Risk of local property flooding

From the Planning Officer’s report to the West Area Planning Committee, December 2017:

“9.149. During the consultation process, reference has been made to the suggestion within the Factual and Interpretive Ground Investigation Report that the proposed drainage strategy will require the use of lime stabilisation to avoid damage to the paving within the car park expansion from changes to the clay layer below ground and that this needs to be given further consideration as part of any drainage proposals for the site. The concerns raised are that lime treatment is likely to have an impact on the permeability of soils below the car park, and therefore needs to be appropriately considered. 

The applicant has confirmed that the surface water drainage strategy has been designed as a tanked system which assumes no infiltration below the attenuation layer, with all storm water discharge from the site via a controlled outfall into Seacourt Stream. An impermeable membrane is included within the construction to prevent water saturating the clay. The underlying clay is of a low permeability whether lime stabilisation is employed or not, and it is envisaged that the attenuation will operate effectively in either scenario.” [emphasis added]

There is no mention in the Application of tanking, nor of an impermeable membrane. We have therefore not known of this till very recently and had no opportunity to comment. While there is little or no detail, the idea that the car park may be separated from the underlying groundwater table, as this implies, raises an extremely serious question. That is, where will the displaced groundwater go? This is a lot of water over such a large area. It is likely that it will cause a significant rise in groundwater levels around this low-lying site. This could cause (new) groundwater flooding within houses (and gardens) nearby. No decision should be taken until the details of  what is planned are made clear, appropriate calculations and modelling done, and presented as part of a further revised Flood Risk Assessment.

[By the same token, when it rains, water will be trapped within the tanking , draining only slowly – more pumping needed?]

New Chair of RFCC visits Oxford

The recently appointed new Chair of Thames Regional Flood and Coastal Committee (RFCC), Professor Robert Van de Noort, visited Oxford on 19 October with EA staff. He was briefed on the Oxford Flood Alleviation Scheme and then shown the Seacourt area at the western end of the Botley Road, which marks the northern end of the Scheme.

We were pleased to meet Professor Van de Noort in South Hinksey, where he went on to see both the lie of the land where the channel will come past the village and on to Kennington to the south, and the earthworks done in the village itself to make the village ‘temporary barrier ready’ for the coming winter and beyond.

Debris

An alert resident has reported to us that a large drain on the path from the end of Duke Street to King George’s Field is partially blocked. Our intrepid Nick Hills has investigated and whilst he was able to remove sticks and twigs that were probably stuffed into the drain by children, there is still a considerable amount of debris that needs to be cleared from the connecting pipe. We think that the County Council installed this drain (to help with flood relief) and we’re asking them to look into it (pun intended).

We’re happy to receive reports of obstructions in drains, trees in waterways and so on. It can be difficult to know who is responsible – we can usually help with that and with reporting the problem. Details of where the problem is are obviously essential and photos are very useful.
