My Lords, perhaps I may take the Minister back to the response that he gave to the noble Lord, Lord Inglewood. The kind of building that goes on in towns and cities—this is particularly true in London—can exacerbate the risk of flooding. I give as an example the frequent removal of front gardens in densely populated urban areas and the substitution of hardstanding, which is usually to accommodate cars. When there is inundation, the effect is often not on the houseowner who has done that but on others. I am old enough to remember a serious example in London about 40 years ago when a very hot summer was followed by extreme rain, and the impact of water running off Hampstead Heath was that many houses at the bottom of that incline were flooded. As we know, that sort of thing is more likely to happen as extreme weather events become more common. Does the Minister think that it is time for planners to take a more active part in preventing that kind of low-level Intervention by individual houseowners who exacerbate the risk of flooding?
