My Lords, I am pleased to endorse the comments made by noble Lords from around the Committee on these amendments. The recent floods brought into sharp focus that the
damaging effects of climate change are not being matched by our skills in managing increased water flows. Both the Government, through their establishment of the national flood resilience review, and the Environment Agency are being forced to reconsider their flood management strategies.
In the mean time, there are steps that we can take that will make a difference, and we have heard examples this evening. It is now commonly accepted that the removal of trees and hedges has reduced the absorbency of our land. In urban areas, the paving over of gardens and green spaces has left nowhere for excess water to drain. The building of new dwellings connected to the existing sewerage system takes no account of the need for increased capacity. At the same time, it remains literally incredible that housing developers apply to build new homes in areas designated as a flood risk by the Environment Agency, and even more incredible that some local authorities continue to grant planning permission in these circumstances.
So we very much support the concept of sustainable housing development, and these amendments are important in bringing some sanity back into the planning process in this regard. Sustainable drainage systems need to be a core feature of future planning, using green space and natural water features that can mimic the known advantages of natural land drainage and help return water flows to a natural equilibrium.
Whether these principles should be applied cannot be left to local interpretation. Sadly, what we have learned over the past few winters is that inaction in one place can often have a catastrophic effect further downstream, so localised decision-making is not the answer. The rules have to be applied consistently, and this, of course, is what Schedule 3 to the Flood and Water Management Act attempted to achieve. It remains inexplicable that the schedule was not enforced in the first place; I hope that the Minister will be able to explain the reasoning behind that. Now is the time to put that matter right.
Amendment 120 is an excellent attempt, once again, to try to rein in the perverse activity of developers building homes on designated flood areas. When this happens and properties subsequently flood, we are all drawn into the net of supporting those communities and helping them turn their lives around, whereas the developers can simply walk away, having pocketed their profit. They do not even have a responsibility to warn potential purchasers of the risk inherent in the purchase of those properties.
This amendment, therefore, puts the responsibility and the financial risk firmly back in the hands of the developers, which is where it belongs. It will hopefully be a tool to encourage more responsible and appropriate housing development in the future. A number of comments have been made this evening on the technicalities of that amendment, and I know that some more work will need to be done on it, but we very much support the thinking behind it.
