My Lords, although this is very much a local matter in Sheffield, it raises the question of the value of trees and how much we care for them. The situation there is that a civil engineer is being asked to look after trees that he does not properly understand. I think the very least that the Minister could do is think about encouraging every local authority to put the issue of trees much higher on their list of priorities than they are at the moment.
My Lords, I agree with my noble friend: trees are incredibly important. They are important not only for the well-being of the environment and the communities who live in it but also in recent months we have seen how important trees and good tree planting are in guarding against flooding.
(8 years, 7 months ago)
Lords ChamberMy Lords, over this Parliament, the Government will commit £2.3 billion for flood defences and the flood maintenance budget will be protected. In 2015-16, £171 million will be invested. There are pockets of funding in addition to that: there is £40 million for Storm Desmond and Storm Eva, as I said, and £4 million has been committed in match funding in respect of the charitable donations that have so kindly come in.
My Lords, along with their many other excellent qualities, trees have a massive part to play in this battle against flooding. I urge the Minister and the Government to do all they can to encourage the widest tree planting possible in the areas liable to flooding, as a matter of urgency, so that we can make the maximum use of this invaluable resource.
My noble friend is absolutely right that trees are a very effective mechanism in terms of mitigating floods and slowing flood waters down. However, the storms we had over Christmas, Eva and Desmond, were too severe for this alone to have been an entire solution. We have to look at all the various solutions in the round, including managing the flow of water, to help to prevent such problems in future.
My Lords, I thank all noble Lords who have taken part in this debate, but particularly the noble Baroness, Lady Jones. As we all know, she is the fully committed Green voice in the House of Lords, and we thank her for it.
I will go through the various questions and points that noble Lords made. The noble Baroness, Lady Jones, started off by talking about the cumulative effects of paving over front gardens—not just the odd one here or there. In fact, in bringing forward local plans now, local authorities should work with water and sewerage companies and other infrastructure providers to assess the quality and capacity of the infrastructure in question to meet the forecast demands.
The Environment Agency produces maps of areas susceptible to flooding—certainly I know a few near myself, for example, in Salford. These maps provide the basis for the strategic flood risk assessment, which local authorities should use in preparing their local plans. Even small development applications in flood risk areas should prepare a flood risk assessment and set out how risks will be managed. It is important that new homes are not brought forward where they would be at risk of flooding, unless they can be made safe and resilient—and without increasing flood risk elsewhere, of course.
Most noble Lords mentioned the balance between the off-street parking demand and the impacts it will have on the local environment; the noble Lord, Lord McKenzie, concluded by saying that there does not have to be a conflict between the two. However, on-street parking or parking on pavements can cause congestion, and, as the noble Lord also said, can be a hazard to disabled pavement users, pedestrians and other road users. The permitted development rights allow a householder to make use of their front garden, while at the same time ensuring there is a provision for surface water drainage; that is crucial as regards the flash-flooding events that we have seen so many times over the last few years.
The RHS report complements the permitted development right by offering ways in which the householder can maintain some planting while meeting their parking need. Its advice on paving front gardens supports the requirements of the householder’s permitted development rights for hard surfaces. The RHS suggests that hard surfaces should be made of porous material, which many noble Lords mentioned today, and it gives several pieces of advice on what material might be appropriate. I heard the other day about a moss-type substance, which you can put in place of a hard surface on the drive; after you drive out in the morning it springs back to life again and is not affected too badly by reparking your car on it. So there are some very good suggestions; my noble friend mentioned Welsh slate, as well. However, if the surface is not porous, there should be a run-off to a porous or permeable surface in the garden, which could be a flowerbed, grass, or another greened area.
The Government take the issue of flood risk—which as we all know has been an issue over the last few years—and the idea of sustainable drainage, very seriously. There is strong planning policy and guidance on assessing, avoiding and managing flood risk for new development, as I mentioned earlier.
The noble Baroness challenged us on whether we had read the report. We have all read it, I hope. It is a very practical guide that we could all use. These things are applicable not only to government policy but also to the individual and how we all play our part in helping the environment and mitigating flood risk.
On permitted development rights and the permeable hard surface, if an area is more than five metres square, that hard surface is required to be permeable. The noble Baroness also talked about the heat island effect. Planning guidance on climate change advises local planning authorities, when preparing local plans and taking planning decisions, to pay particular attention to integrating adaptation and mitigation approaches that will support sustainable development: for example, maximising summer cooling through the ventilation of buildings and avoiding solar gain, and by providing multifunctional green infrastructure which can reduce urban heat islands.
My noble friends Lady Fookes and Lord Skelmersdale and the noble Baroness, Lady Jones, talked about enforcement by local authorities. Local authorities, of course, are responsible for enforcement and can make householders take up paving and replace it with a permeable surface. I think that it was my noble friend Lord Skelmersdale who asked how effective enforcement is. I do not have figures to hand but if I can get them I will and I will place a copy of the response in the Library as well.
My noble friend Lady Fookes talked about the value of tree-lined streets and the idea of green infrastructure. I could not agree more. There is nothing more off-putting than a grey house without any planting at all. Trees really enhance the economic value of property, both domestic and commercial. You only need to look at places such as New York, which I think is one of the finest green cities—
My particular interest is trees but I have found this whole debate fascinating. I was once a Member of Parliament for part of Ipswich and most of it has been covered like this. It is very serious. It needs to be stopped somehow and my suggestion might be that we cannot ask local authorities to do too much. We heard from my noble friend Lady Fookes about the Chelsea exhibit, where you can park a car and have the porous surface and cars. Might it be an idea to encourage local authorities just to do one of these—one or two in specific areas—to show what can be done? People love to copy things and if they think it is all happening, they might well do it. That might just be a way forward.
It is funny, because the next point I was coming on to make was that my noble friend also said that where there are good examples of what people do, others will follow. Certain local authorities see great value in planting trees and keeping the green environment in a fine state. I think local authorities can lead by example. Coming back to New York, it is one of the finest examples of a green city in the world and yet it is very built up as well—so you can do both. I do not think that we will introduce legislation to force councils to plant trees, but there is no doubt that where trees are planted you enhance the environment and people’s well-being in every way. My noble friend Lady Fookes mentioned the health benefits. They are undeniable.
My noble friend Lady Fookes also mentioned clay soil drying and leading to subsidence. Building regulations now ensure that the design of foundations avoids subsidence problems in clay soil areas and building control bodies often have additional local requirements in this regard. But we need to use these permeable surfaces as run-offs in permitted development rights to help minimise those problems.
My noble friend Lady Fookes talked about biodiversity, which is absolutely right. It goes hand in glove with the health benefits and the whole appeal of an area. Our bee population will not survive in concreted areas. The noble Lord, Lord McKenzie, talked about the housing crisis. In fact, we have exceeded the target of 260,000 affordable homes and there will be £38 billion of public and private investment to help ensure that 275,000 new affordable homes are build during this Parliament.
My noble friend Lord Skelmersdale questioned whether this was an environmental debate or a built environment debate. It is probably more of the latter. I am happy to have responded in this debate and if I have left out any questions asked by noble Lords, I shall answer them in due course. I thank all noble Lords who have taken part.
