Flood Defences (Thurnham, Lancashire)

Eric Ollerenshaw Excerpts

Tuesday 29th October 2013 Westminster Hall

[Eric Ollerenshaw (Lancaster and Fleetwood) (Con)]

It is a pleasure, Mr Streeter, to serve under your chairmanship and to welcome the Minister to his post. I congratulate him on his appointment; I am sure his response at the end of this debate will show him to be a wise and listening Minister.

Thurnham is a small part of the parish of Glasson Dock, on the edge of Morecambe bay. The sea defences are situated in the Cockerham and Thurnham areas of north-west Lancashire, running approximately 7.7 km from Cocker Bridge on the A558 in the south to Janson Pool in the north, south-west of the port of Glasson. They form an integral part of the west Lancashire coastal defences, providing protection against tidal inundation from what is essentially the estuary of the river Lune as it goes into Morecambe bay.

The area has been subject to flooding damage through overtopping and breaching of the existing defences in the past. The most recent floods occurred in 1977, when approximately 540 hectares of land were affected, and in 1983 and 1990, when approximately 50 hectares were flooded. As one can tell from the description, it is mainly a lowland mixed farming area, with sheep and some dairy. There are also important tourist facilities in the form of caravan parks, scattered residential housing and one listed monument in the remains of Cockersands abbey.

In 1999, Jacobs Engineering completed a business case for Cockersands sea defences, which proposed a “hold the line” option. In January 2004, a reappraisal of the economic business case to refurbish the existing defences was undertaken by Jacobs. It concluded that no capital scheme could be promoted, although it recommended that further options, including managed realignment or continued maintenance, could provide a better business case.

In November 2004, a further study was undertaken to consider the recommendations of the economic reappraisal, and that determined that a managed retreat scheme could be the right economic method, even when all the land and buildings were written off from tidal inundation and purchased at their market value. In arriving at the conclusions, Jacobs recommended that a physically based model to simulate onshore tidal inundation and onshore wave inundation for different return periods was undertaken as its conclusions were limited by the quality of the available flood spread information.

Consequently, maintenance activities continued, in line with the original recommendations from the shoreline management plan. In January 2008, Jacobs completed a technical report, investigating the effects of tidal flooding should the existing defences be removed, as well as the several managed realignment options identified in the 2004 studies. In 2009-10, the shoreline management plan was updated by Halcrow and recommended that a “hold the line” policy should be adopted for years nought to 20, followed by managed realignment for years 20 to 100. The shoreline management plan updated the economic appraisal in line with the latest guidance.

I have raised this debate because I am trying to establish something. Since 2010, there has been a series of meetings between Environment Agency officers on the ground and the Cockersands Forum steering group, which was established by the parish council. All those meetings have been open and transparent, and shared information has gone backwards and forwards, but we are now getting to the point where certain fundamental policy decisions need to be made by Ministers if we are to make any kind of progress.

The Cockersands Forum steering group, which is formed of residents, considered that the flood defence rebuild costs that were put in by the Environment Agency were inflated, and that the reports of the overtopping events from past flooding were inconsistent with their own knowledge of the history of what had happened. Interestingly, I understand that in the middle of the discussions between the agency and the local residents, through the forum, when the sea defences were looked at properly and people walked them, the agency was prepared to admit that the defences were in a better state of repair than was perhaps first apparent.

The discussions have got to the point where the Environment Agency has been prepared to say that it will hold the line for 30 years. That was something better. Clearly, however, the fact that the defences will be maintained for only that amount of time will have a significant impact on the value of residential homes and businesses. How can people in this area now sell or invest for the future, knowing that there is possibly a 30-year time limit, after which the defences will not be manned? The issue for them is this: how can any Government simply let good farming land, good housing and good businesses be slowly ruined, based on assumptions about possible sea levels in 30 years’ time?

It seems ridiculous that lives can be ruined on such speculation when there is no exact science, yet the plans in place already mean that there is blight in the specific area and particular residents are unable to sell their properties, despite wanting to move on because of age or family circumstances. In a sense, it is a death knell to Thurnham and the surrounding area that there can be no movement in and no movement out.

The residents are practical people; as you and the Minister well know, Mr Streeter, we are all practical people in Lancashire. So the residents took the matter further and looked at all the past evidence they had, in the form of photographs and written evidence, about the 1977 flood. They came up with an extremely sophisticated diagram of what had happened in that year. What they proved to the Environment Agency—to be fair, the agency accepted it—was that it was possible to see in some of the historical detail that the flooding covered a much wider area than was set out in the original Environment Agency plan. That, at least, is my understanding.

Now we are in a strange position. My understanding is that the Environment Agency has accepted that local residents, through their knowledge of history and what they have produced, have demonstrated that if the defences go down, a much wider area will be flooded than was set out in its original statement. However, strangely enough, that does not affect any of the agency’s cost-benefit analysis between its original assumptions and its present-day assumptions. It still wishes to stick to a policy of “hold the line” for 30 years and after that to manage retreat, leaving the area, as I have said, to the depredations of the sea and whatever we can predict about the sea and rivers in 30 years’ time. So the strange position is that although residents, to my knowledge and that of the Environment Agency, have demonstrated that a bigger area will be flooded in the future, that will not affect the cost-benefit analysis.

One of the key determinants appears to be the cost-benefit figure that the Treasury established in respect of losing farming land in particular. I understand that this is a long-established Treasury figure, which takes no account of rising population, both here and across the world, or of the increased concern that we all have—in whatever country we live—about food security.

I wish to ask a particular question of the Minister. If my assumptions are correct about this cost-benefit analysis, are his Department or the Treasury, or both, doing any work to look again at revising the old cost-benefit of farming land, given the national situation in terms of population growth and the political concerns among all parties about food security?

Secondly, let us take the boundaries of my constituency and that particular part of the west coast of Lancashire. At the end of my constituency is the town of Fleetwood, where the Government have just agreed—I am grateful for it—that £65 million is to be used to improve flood defences. The Rossall sea wall needs to be demolished so that a new wall can be put in. It will protect 12,000 homes.

However, from the outside it looks as if the Lancashire coast is being dealt with in separate sections. Fleetwood, quite rightly, gets £65 million; the sea wall there needs attending to. If anyone sees that sea wall, they will know that it is like the Berlin wall. The poor residents need something that might look better and might do a better job. However, just along the coast, there is another village called Pilling, where I have regular meetings. Again, that is a lowland area, next to Thurnham, where there are also concerns about flooding and land drainage. Yet at the Pilling meetings, there is no mention of what is happening next door in Thurnham. That might be because Thurnham comes under Lancaster district council and Pilling comes under Wyre district council. Nevertheless, it seems a bit odd, because my understanding of water is that when it comes through the dykes or over or through the sea defences, it does not worry whether it is flooding Pilling or Thurnham, which are next to each other.

One question that I have for the Minister has already been asked by people in local parishes—what happened to the old land drainage boards, which used to cover wider areas? Also, is there a bureaucratic impasse because of different council boundaries? Do we need to consider a better structure in the long term? That might not be the land drainage structure of the old days, which I understand was somewhat bureaucratic—but at least it involved local landowners, on a wider scale, in the nature of drainage and flooding of their areas.

Will the Minister consider looking at a different vehicle, which could involve, yes, the parishes, villages and local residents in some form or fashion and enable them to cut across the district councils and look at land drainage areas as they are—that is, as geographical drainage areas that do not respect council boundaries? Perhaps we could deal with some kind of operation in those terms.

My understanding is that there has been some discussion on the east coast of this country about such schemes, and that there are still some leftover remnants of the old land drainage boards around the place. They might give us some pilot schemes to see whether the boards could be revamped in the ways I have outlined.

What the people of my constituency, in my part of Lancashire, are looking for is a wider look at what the Government’s plans are for the future. How can a Government spend so much money—quite rightly, in the case of Fleetwood—to protect one part of the coast, and then leave another part to the vagaries of what the science presumes will happen in 30 years’ time: sea levels will be somewhat higher and farming land will not be as valuable as it could be? Farming land is not as valuable as people’s lives, of course; I accept that. Somehow we do not seem to see what the wider plan for the area is. If my residents were able to see and understand that wider plan, they might have a better way of grasping what the Environment Agency’s and the Government’s policies are.

I am particularly interested in learning what the new Minister—the new broom, as they say—might want to do to offer some succour to people across my constituency, whatever district council they belong to. Some have suggested that there is a deliberate attempt to carve off one village against another. I would never support such conspiracy theories; I simply think that it is good old bureaucracy again.

The third thing that I want to raise is a little blue-sky thinking; although we are practical in Lancashire, we can think outside the box. If the Environment Agency is going to hold the line and if the Government are going to supply the money to keep the sea defences going for 30 years and then make a decision—we have not discussed this with the parish council, although it has been talked about in the area generally—could there be a special levy in the area as part of the parish rate, which could go into a fund to be invested for 30 years? We wanted to describe it as a sinking fund, but since we are talking about flooding, let us talk about a floating fund.

If the levy was £25 a year, let us say, with 500 residents paying it, in 30 years there would be more than £300,000 before interest. Any parish or group of residents would be in a very strong position, whoever the Government were in 30 years’ time. If they had a body of money to contribute, it would make it much more difficult for the Government of the time to say, “We are still going to abandon the defences.”

I have discussed the levy with the district council. If there were such a charge, and if somebody wanted to buy a property, would it appear in the land charges office? If it did appear, would the fact that it was offering another stage of protection help to maintain the values? This is anecdotal evidence, but various estate agents in Lancaster feel that it would help to maintain values and keep that exchange of property and businesses going on, because there would be further protection building up over time.

Interestingly, the council said there was nothing in law that would allow it to specify such a measure on a land charge. However, that might not be needed. It might simply need a parish rate and a parish flood defence rate. I do not know. I assume that when searches are made, the council charge and parish charge come up, so perhaps we could come up with a flood defence charge.

As I said, this is blue-sky thinking. The residents have jobs to do, and we are all trying to find a practical way to assist Government and the Environment Agency. It would be really helpful if some of the experts, who I know exist in the Department, could look at the idea. It might mean talking to the Department for Communities and Local Government.

The residents of Thurnham are trying to find a way in which they can be seen to be helping themselves, but, for 30 years—perhaps even longer—they need Government support to protect the land that they have bought, where they have built their businesses, or have retired to, or where they run their farms.

I did not secure this debate because of any angst with the Environment Agency. I can see an officer here from the Environment Agency; we have met on several occasions. The agency has dealt with the matter absolutely transparently in an up-front way and with a great deal of sensitivity and understanding. We are talking about people’s lives, businesses and properties, and I pay due credit to it. However, we have now hit an impasse and we need Ministers to start looking at the policy implications.

If the problem exists in Thurnham, which is a small part of Lancashire—obviously dear to me as part of my constituency, and even more dear to the people who have built their lives and businesses there—it must exist across the piece. It cannot be right for any Government to take a 30 or 50-year view that somehow, because it is mainly agricultural land, it will be worth less than it is today. If people are willing to try to find a vehicle to help themselves and to join with the Government in maintaining the sea defences, it cannot be impossible to find the time, effort and brains to provide them with a little extra help.

I will be delighted to hear the Minister’s comments about those three points. I understand that he cannot say yes, but if he could stand up and say that Thurnham will be protected for the next 100 years, I would be more than grateful. I understand his position. He might need to take the issues away, but Thurnham in Lancashire is willing to help and to offer ideas. It desperately wants to keep the livelihoods of people who have farmed there for generations. Generations of family life have gone into that particular area, and they simply want a future for themselves, their children and the people of Lancashire, and to keep a beautiful part of Lancashire safe from the sea.
