Flood Defences

Anne Marie Morris Excerpts

Wednesday 6th July 2011 Westminster Hall

[Richard Benyon]

I recognise the point that my hon. Friend makes and it is now on the record. My officials and I will look carefully at it. However, that is not the information that I had when preparing for this debate, so I will take that point away and get back to her.

Let us look at the case that my hon. Friend raises, because it is important to understand the history. I apologise to other hon. Members who might wish to intervene, but I have only a few moments left. My hon. Friend called this debate and I want to be able to answer her points. Last September, an independent reservoir engineer was appointed to assess the proposals in the context of the Reservoirs Act 1975. The Act is designed to ensure that public safety is maintained. The engineer acted in accordance with guidance produced by the Institution of Civil Engineers. At that stage, the engineer identified the reservoir as a category A reservoir. That classification means that a breach of what could be an 85,000 cubic metre reservoir could seriously endanger a community—we have already discussed what constitutes a community. As a result, it is only right that the highest standards of public safety apply. At best, a failure would increase the level of flood-water, thus defeating the purpose of the scheme. At worst, a catastrophic failure would result in human tragedy. The engineer agreed necessary design standards that should apply in this case to maintain public safety.

In March, new modelling led the engineer to conclude that a higher design standard was necessary. In May, a second opinion was sought, again from an independent reservoir engineer. The second opinion confirmed that the Institution of Civil Engineers guidance on the 1975 Act had been correctly applied and that a higher standard was needed. That led to a redesign that incorporated the higher design standard of the spillway, to which we referred earlier. Inevitably, that pushed up costs. Despite the significant local investment already on the table, the shortfall in funding amounted to around £2 million. Frustratingly, at that level of cost, the scheme is not cost-beneficial under the Treasury Green Book rules. It is not my view that the guidance is wrong. That said, the case does underline the sense in reviewing the guidance. That is a firm assurance that I can give to my hon. Friend today. A review on highly technical guidance—I have already referred to the complexity of the document—is not a quick fix, and will require broad engagement. In the mean time, I welcome efforts to reassess these proposals.

The reservoir is clearly an important part of the plans for the area. That said, I know that many of the innovative approaches that my hon. Friend has described are continuing in parallel. It may well be that we can fairly quickly achieve a different scheme that complies with the Reservoirs Act 1975 and has a sensible cost frame and a sensible cost-benefit analysis result. All the work going into reviewing the guidance will not affect the implementation of the Flood and Water Management Act 2010. If it does, Ministers will have the power to apply other criteria to assess whether, on the balance of risk, it is right that these schemes should go ahead even with the lower threshold.

The reservoir is clearly an important part of the plans for the area, so I genuinely applaud the real openness and innovation. There has been engagement with the local authorities, local landowners and many other partners, and leadership from my hon. Friend.

The Environment Agency and local partners are working hard to reassess the designs and to drive down costs. Other options that were originally put forward are also being discussed. Once consideration is complete—I expect that to be at the end of July—the agency is eager to continue working with local partners to explore what can be done while maintaining public safety.

I am sure that the Minister will listen carefully in this case, as he did when he enabled me to have a flood scheme in Teignmouth, for which I am extremely grateful.

[Richard Benyon]

I am grateful to my hon. Friend for coming to this debate; not all hon. Members come to debates to give a thumbs up. The difficulty with flood defences is that we only know that they work when issues are not raised because problems have been resolved. I know that the issue is a burden for the constituents of my hon. Friend the Member for Thirsk and Malton, the right hon. Member for Oxford East (Mr Smith) and the hon. Member for Wansbeck (Ian Lavery). There are serious problems affecting communities around the country. We are changing the way in which we approach flood funding.
