My Lords, I am conscious of the fact that noble Lords are dying for me to shut up, because I am probably all that is between them and going home. But I think that this is an important issue—and it is important for two reasons. I rise to promote Amendment 119 in my name and support Amendment 120, proposed by the noble Lord, Lord Krebs. There are 4 million people at risk of surface water flooding and climate change, and increasing urbanisation will make that worse, so it is a really important issue. More important is the fact that this Parliament agreed the Flood and Water Management Act 2010, which included provisions for sustainable drainage—but the relevant sections have not been commenced. I am very ambiguous about the Government’s habit of not bringing into being the will of Parliament. Instead, they have decided to rely on planning measures through the NPPF and have provided two pages of non-technical standards to guide developers.
The presumption in planning that sustainable urban drainage should be included in new developments is not working. It has created uncertainty for developers and created a diversity of interpretation of what is acceptable. Planning authorities—poor souls—are leaned on to ignore it if developers suggest that the costs of providing sustainable urban drainage affect the viability of the development. Local planners at the moment have neither the expertise nor the time, and cave in under these viability challenges.
As the noble Lord, Lord Krebs, said, the planning rules include no structure for formal adoption or long-term maintenance of sustainable urban drainage schemes, which has been a problem for years, with schemes being created and then left orphaned with nobody to look after them and make sure that they continue to be safe and effective. Of course, it is not just about sustainable drainage and flood protection. There are also potential additional benefits of amenity, water quality and biodiversity that have not been garnered.
I had the privilege of talking briefly to the Minister about this and she indicated that the Government’s intention was at least to run the scheme on the planning presumption basis for two years while it was monitored. My further inquiries since meeting her have revealed that no body has been charged with keeping these records—so I am not clear that the Government will be able to say at the end of the two-year period that the scheme is or is not working.
So far, the evidence we have been able to glean from people such as members of the Chartered Institution of Water and Environmental Management—of which I should declare that I am an honorary fellow—is that the situation is now worse since local flood authorities took over responsibility for surface water drainage. Noble Lords have heard the figures from the adaptation sub-committee and the quotation from Barratt Developments that about one-third of its developments do not include sustainable drainage.
We appear to be fiddling while Rome burns in anticipation that at the end of two years, we will be better informed, when in fact the figures will not be available to demonstrate whether it is working. We should press for the implementation of Schedule 3 to the Flood and Water Management Act. That would fulfil Parliament’s will, cost no more than conventionally engineered drainage systems, help reduce flood risks and the costs of flooding, provide improvements in water quality, biodiversity and amenity and give developers a degree of certainty.
In the interest of brevity the noble Baroness, Lady Parminter, said she would not list the diverse range of expert bodies. I will list but a few of them: the Institution of Civil Engineers, the Royal Institute of British Architects, the Chartered Institution of Water and Environmental Management, the Construction Industry Council and a few others—I have forgotten what the acronyms stand for, so I shall not bore noble Lords with them. We should re-enact your Lordships’ previous support for this provision, which is enshrined in legislation.
I support the interesting Amendment 120, which was tabled by the noble Lord, Lord Krebs. When I first read it and was asked to support it, I was slightly wary because it seemed to be a bit bonkers. But, having thought about it and having read it in detail, I think it is one of the more cunning pieces of win-win, incentive-based legislation I have seen for many a long year, in that it would mean that developers would have to think harder about developing more flood-resistant properties and about developing on less flood-prone sites in a way that would not require any cost from them provided they did it well. That is what a good amendment looks like, and I commend it to the Government.
