Flooding

In the cost-benefit analysis of flood defence work, one of the crucial factors is, quite rightly, the probability of a flood taking place. In my constituency we have had two ““one-in-30-years”” floods in the past nine years, and that is common, certainly in the west midlands. I wonder whether the Secretary of State can assure us that in his review, that formula will be reconsidered, because projects that did not look viable on a one-in-30-years basis may well have a very considerable positive value on a one-in-10-years basis.
