Housing: Floods

Question for Department for Communities and Local Government

UIN HL5515, tabled on 27 January 2016

To ask Her Majesty’s Government what proportion of new houses built in each of the years from 2010 to 2015 were built on floodplains, and whether they expect that proportion to change in the next five years.

The department’s latest land use change statistics provide estimates on the proportion of new residential addresses created in National Flood Zone 3 in England. The latest figures show that in 2013-14, 7 percent of new residential addresses were created in the National Flood Zone 3. This equates to an estimated 9,100 homes being built in National Flood Zone 3 in 2013-14.

Prior to the publication of 2013-14 figures land use change statistics were calculated using a different methodology so they are not directly comparable to the 2013-14 figures. Figures produced using the previous methodology were last published for the calendar year 2011 and are provided in the attached table.

Development can not be ruled out in high flood risk areas as around 10 percent of England, including large parts of major cities, such as Hull, Portsmouth and central London are located in these areas. All local planning authorities are expected to follow the strict tests set out in national planning policy and guidance, which includes steering development away from flood risk areas. Where development in flood risk areas is considered, national planning policy is clear that it should be safe, resilient and not increase flood risk elsewhere.
