Flood Defences

Debate between Andrew Smith and Baroness McIntosh of Pickering

Wednesday 6th July 2011 Westminster Hall

[Miss Anne McIntosh (Thirsk and Malton) (Con)]

It is a privilege and pleasure to serve under your chairmanship, Mr Bayley, as my immediate constituency neighbour and someone who is familiar with the problems of flooding in Yorkshire.

I am delighted to have secured this debate on the implications of the potential delays to planned flood defence systems. In the short time available, I want to focus on a technical point and relate it to my constituency, North Yorkshire and Yorkshire and the Humber, areas with which I am familiar. I hope to put to my hon. Friend the Minister a once in a lifetime opportunity. I am sure that there are occasions when he lies awake in the middle of the night wondering what he can do, in what one hopes will be a long ministerial and parliamentary career, to make a difference. I suggest that he has an opportunity here and now to make a difference to a large number of people not only in Pickering, Thirsk and North Yorkshire, but in the rest of the country.

The Minister is familiar with the background to the scheme, and I am delighted that the Secretary of State had the opportunity to visit Pickering and see the work on the “Slowing the Flow” project. The Minister will know that the original £6 million scheme for flood defences at Pickering was rejected by the town and the district civic society, but, eventually, in April 2009—with confirmation in 2010—funding for the Pickering pilot project was announced. It is a unique, pioneering scheme, with Government bodies working closely with communities, where there is not an established pot of money. There are particular difficulties with the course and nature of the river upstream of Pickering, which, as you will be aware, Mr Bayley, is where the beautiful North Yorkshire Moors railway is located. The innovative and pioneering scheme involves creating buffer strips along water courses, digging ditches and blocking moorland drains, as well as planting trees.

The scheme was created with the compliance of the landowner and in partnership with the Environment Agency, the Forestry Commission, Durham university, as an academic partner, the North York Moors national park authority, Natural England and Ryedale district council, primarily driven by Pickering town council and the local floods group. There was extreme shock, surprise and disappointment when in June, at the eleventh hour—the technical aspect of the scheme that I want to discuss was due to start this summer—the scheme was put on hold and effectively cancelled, as the cost was deemed to have undergone a staggering increase from an initial £1.3 million to a total of £3.2 million. That was alleged to be due to the requirements of the 1996 guidance to the Reservoirs Act 1975, which is the focus of my questions to the Minister and of my call for action.

The guidance states that the bunds must be able to withstand a one in 10,000 year flood event. However, one local, who is expert in the matter, has said:

“While I appreciate that more detailed modelling and info was constantly coming to light to influence the res engs decision, the fact remains that the critical factors of bund capacity of 85k m3 and the number and proximity of properties at Newbridge remained constant throughout.”

You almost could not make this up, but I did not appreciate before preparing for the debate that a community is 10 properties. Were there only nine properties at Newbridge, the scheme would proceed apace. There would be no cause for delay or concern about the reservoir. Newbridge has been there for far longer than the proposed scheme.

One option—not my favourite—would involve the compulsory purchase of one of the dwellings or properties at Newbridge. That would be the most regressive and least favoured option, but it shows how daft it is that some of the definitions, such as the number of properties that form a community, lead to perverse decisions. As my constituent goes on to say:

“I just cannot understand an anomaly within effective legislation that allows this.”

That is a reference to the fact that the interpretation of the Reservoirs Act 1975, through the guidance, is either woolly or misleading. Although it appears on the one hand that high-risk criteria are precisely laid down, there appears to be a get-out clause to lower the classification to low risk. My constituent concludes:

“I shudder to think what these obligatory Res Engineers are being paid”—

that is his personal comment, I hasten to add—

“but there is something seriously wrong when their interpretation can vastly alter the design criteria from one month to the next when all the physically present criteria remain constant…unless the application of common sense is overtly permissible.”

[Mr Andrew Smith (Oxford East) (Lab)]

Will the hon. Lady give way?

[Miss McIntosh]

I wish to make progress.

I do not want to use the debate to apportion blame. I want to use it in a constructive way to urge the Minister to remove the barriers to this project and to other projects. There are similar difficulties in Thirsk, and the common thread of the flood defence schemes is that part of the project in both Thirsk and Pickering allows a storage bund to be created. However, that is now being defined as a reservoir under the Reservoirs Act 1975. My conclusion is that the projects are being over-engineered with structures that are too complicated, and falling foul of the iniquitous 1996 guidance note to the 1975 Act. Clearly, there is a gap between aspirations for individual projects, such as the Pickering pilot project and the Thirsk flood defence scheme, and the ability of the Environment Agency and others to deliver on such schemes.

The Pickering bund scheme has highlighted a lack of clarity about high risk and lower risk in the 1975 Act, and, therefore, a major disconnect between legislation and guidance. There is little guidance beyond the matter of actual reservoirs. It does not seem sensible to build bunds to withstand a flood of biblical proportions, when communities downstream of 8,000, 10,000 or 14,000 properties are being held back by a community of 10 properties. Those communities downstream, in that eventuality, would already be both evacuated and in any case devastated. I agree with another of my constituents that that massively over-engineered standard is denying Pickering residents protection from repeated and frequent flooding. Will the Minister confirm that the return periods are based on data since the late 1980s? In that case, one in 10,000, or 235 cubic metres per second, can barely be described as an educated guess. On what basis were the figures reached? Pickering starts to flood at 12 cubic metres and seriously floods at 15, but in 2007 there was approximately 29 cubic metres. At 235 cubic metres—the one in 10,000 years risk—the town would be devastated and possibly extinct. The Flood and Water Management Act 2010 contains no specific provisions for bund schemes of this type.

I turn next to the personal liability of reservoir engineers in the event of structural failings. It would be totally impractical to ask the two reservoir engineers to risk their personal liability, as it would result in hugely over-cautious, over-engineered and therefore over-priced structures. Liability needs to be shifted from the individual to a public body such as the Environment Agency—or, in my view, the Environment Agency’s political master, the Minister.

Well over £1 million has been wasted in Pickering, and it has produced nothing. We do not want more feasibility studies, consultants or modelling unless specifically needed for a bund. There is a scheme on the table, which everyone believed would work, and there is a great desire and the practical and political will to make it work.

I shall take this opportunity to put a number of questions to the Minister and to tell him of a number of possible solutions that I have identified. The “Slowing the Flow” project in Pickering has been hampered by the fact that although it is a demonstration project, and although part of it is already under way—I have mentioned the creating of buffer strips, the digging of ditches, the planting of trees and the blocking of moorland drains—I am told that no engineer has yet quantified the volume of water that will be retained. That is staggering, given the work that the Conservative party did in opposition, the fact that the Department recently produced its natural environment White Paper and the work undertaken by a number of water companies.

“Slowing the Flow” was always a demonstration project. Implementation requires a major policy change by the Environment Agency, from highly expensive hard defences to affordable simplicity. We should keep things as simple and unstructured as possible, working with nature as closely as we can. However, that appears to be outside the engineers’ and the agency’s comfort zone. Where is the expertise? Is the answer in the White Paper? Is it already known by the water companies? If it does not exist, it should be developed. Is the Department minded to develop it?

The key to this debate is whether the Minister has the power to vary the 10,000 and 25,000 cubic metre thresholds. I understand that the reservoir guidance notes drafted by the Institution of Civil Engineers and agreed by the Department and the Environment Agency can be varied. Schedule 4 to the Flood and Water Management Act 2010 amends the Reservoirs Act 1975. New section A1(6) of the 1975 Act states:

“In making regulations under subsection (5) the Minister shall aim to ensure that a structure or area is treated as large under the regulations only if 10,000 or more cubic metres of water might be released as a result of the proximity or communication mentioned in that subsection.”

New section A1(7) of the 1975 Act states:

“The Minister may by order substitute a different volume of water for the volume specified in subsection (3) or (6).”

This is the thrust of my debate. The project could probably go ahead if the Minister were to be bold and use that power of variation. He could also instruct the Environment Agency to replace the dam at Mill lane with an automatic sluice. In the longer-term, he could ask Yorkshire Water to consider storing water underground through enlarged sewer pipes. He could even instruct the Environment Agency to compulsorily purchase one of the 10 properties at Newbridge. I have been reliably informed that the chances of finding extra money or exploring local authority options through the flood defence committee or through development gain are minimal.

This is an individual debate, and I am asking for the Minister’s urgent reply. I urge him to go back to the drawing board to find a similar scheme that can use the £1.3 million already on the table and re-examine the engineers’ judgment that category A status applies to the reservoir and the two bunds upstream. Most urgently, I ask him to waive the reservoir guidance notes by using his ministerial discretion and common sense, for which he is well known.
