asked Her Majesty's Government:

What (a) number and (b) percentage of new dwellings were built in areas of high flood risk in each year since 1997 in (1) England and (2) each government region; and what projections they have made of the number of new dwellings that will be built in areas of high flood risk in each year to 2020.

Between 1997 and 2005, the most recent year for which data are available currently, an estimated 120,860 dwellings were built in England in areas of high flood risk. This is 9 per cent of all dwellings built in this time. The tables below detail the (a) number and (b) percentage of dwellings built in England and each government region in each year.

The Government have not made projections of how many houses will be built in flood risk areas in future years.

1. There is an inevitable time-lag between land use change occurring and it being recorded; therefore data are constantly being updated.

2. The data in the table above are based on records received from Ordnance Survey up to September 2007, consistent with the January 2008 update of LUCS.

3. Figures may not add up due to rounding.

4. The definition of high flood-risk areas used by Communities and Local Government is the high-risk zone mapped by the Environment Agency as being at a probability of flooding, excluding the presence of flood defences, of at least one in 100 each year for river flooding and at least one in 200 for coastal flooding. High flood-risk areas account for about 10 per cent of land in England, including parts of major cities such as London.
