Water Bill

Debate between Lord Grantchester and Earl of Lytton

Tuesday 11th February 2014 Lords Chamber

[The Earl of Lytton]

My Lords, I welcome the opportunity to debate this important point. I declare a professional interest in aspects of planning. The question of planning policy and its co-runner, which it informs, development control, raises some important issues on the ground. These need to go beyond the question of new-build developments alone. I do not know whether the noble Lord, Lord Shipley, intended to address just new-build developments but if he did, perhaps I could digress into the area of what we do about some of the existing building stock, which I flagged up at Second Reading. I alluded then to the desirability of making conditions concerning the containing of surface water run-off within existing individual properties, as opposed to just allowing each to discharge it on to the next property downstream.

I wondered whether this might be made retroactive to a degree, perhaps by requiring extensions and alterations to existing properties to incorporate, in appropriate circumstances, a surface water attenuation scheme. I do not believe that this is a general requirement but there are precedents. For instance, if you renew the roof covering of your house, you are often obliged to upgrade the insulation of the roof of your property. There is an analogy there. Surface water attenuation on a per property basis could also be combined not only with water conservation, but with habitat-friendly outcomes. The same thing could apply to the principle of reducing vulnerability of the property itself—a point made earlier by the noble Baroness, Lady Parminter—in connection with quite ordinary adaptations that can be put in place to prevent properties being so severely affected by flooding, should it happen. There is also the question of community-based schemes to protect groups of buildings. I referred to the Lower Don Valley scheme, but there are others.

One of the things that has come out—sorry, that is probably a bad term—or rather, has arisen recently is the question of making foul drainage systems safer, so that if flooding does happen, flood water does not turn into a solution of dilute sewage, adding health hazards to all the other problems of clean-up. That requires special measures, not least because shared sewer pipes that are on private property but are ultimately connected to a public sewer are now the responsibility of the statutory sewage undertaker. I have this terrible feeling that they have no idea of the routes, the condition or the materials of half of these pipes for which they have now inherited responsibility. They have my sympathy in that respect.

The noble Lord, Lord Krebs, referred to building on flood plains. My only point there is that protecting properties so that they are themselves secure against flooding is one thing. Transferring risks to properties elsewhere is self-defeating. My difficulty is that I am not sure that a holistic approach is taken to dealing with the totality of flood plains. Often, these may be in more than one local planning authority area, so there may be problems of co-ordination. With regard to that, the noble Lord, Lord Shipley, referred to the competence and capacity of local government and the noble Baroness, Lady Parminter, referred to reductions in Environment Agency budgets that might affect its ability to have this overarching, integrated view. I worry about that. It is vital that the sort of report that the noble Lord, Lord Shipley, has in mind covers all these aspects. If we start leaving bits out, we shall be no further forward in a few years’ time than we are now.

I draw attention to the catchment area management plan referred to by the noble Lord, Lord Campbell-Savours. I have some experience of this, not all of it edifying. In at least one instance, I found that half the catchment area concerned, the upstream half, was missing from the plan. The only fact that I could ascertain was that the owner of the missing part was the National Trust. I am unsure what conclusions I should draw from that, but if you have a catchment management plan, the boundary of it has to be drawn along the watershed. No other boundary is possible. The simple arithmetic that was drummed into me, probably from O-level geography onwards, has not escaped me. Making up rules to suit as one goes along will not wash. I am sorry for that terminology as well.

Some time ago, I attended a professional lecture on restoring part of southern Exmoor to a peat bog so that it would hold more water and release it more slowly into the River Barle and the River Exe systems. It had something to do with pumping and repumping water back into Wimbleball reservoir, which I shall not go into. I nicknamed the scheme the “Exmoor sponge”. I do not think anyone else has used that term. There is nothing wrong with such projects, but if they do not have durable management structures that are proof against misuse for commercial objectives, neglect because of spending cuts, simply being forgotten, or participant landowners deciding that there are better land uses that they would rather adopt, they will fail. There need to be more durable ways of dealing with these things. That is the sum total of the points that I wish to make. The last of them probably goes a bit beyond the amendment proposed by the noble Lord, Lord Shipley, but it was worth mentioning in the context of what was said by the noble Lord, Lord Campbell-Savours.

[Lord Grantchester (Lab)]

My Lords, the amendment would set up a review of recent outcomes of planning policy in terms of flood risk for new developments. It has received widespread support around the Committee.

The noble Lord, Lord Moynihan, has already highlighted how the market will change following recent events. In view of the terrible situation that has resulted from recent weather events in Somerset and the Thames Valley, which may well trigger a wide-ranging review of flood risk policy, it makes sense to ask why there has been more building on low-lying and flood risk areas in the past four years, even allowing for the guidance to which the Minister has already referred today. There has been plenty of notice since 2007 that not all property in areas that might be developed would be eligible for flood insurance. Recent floods have highlighted that there may be errors in the guidance. Nor have successful protection measures been achieved.

Why has planning allowed development to take place against a background of increased perception of flooding potential following the floods in 2007 and in 2012? As the Government, the Environment Agency and planning authorities—indeed, the whole country—will be reassessing flood defences and expenditure, a review of where we are now would make eminent sense.

I was struck by the comments of the noble Lord, Lord Shipley, on the cumulative development effect, which would be worth of the attention of the Environment Agency. The amendment has also prompted some interesting suggestions from my noble friend Lord Campbell-Savours, so it is worthy of further assessment by the Government.
