Question to the Department for Levelling Up, Housing & Communities:
To ask His Majesty's Government how many new residential properties have been constructed within Environment Agency flood zone 2 each year, since the financial year 2012/13.
Answered by
Baroness Scott of Bybrook
Parliamentary Under Secretary of State (Department for Levelling Up, Housing and Communities)
The percentages of new residential addresses created that have been within each of Environment Agency flood zones 3 and 2 in each financial year since 2012-13 are provided below. Figures for 2012-13 are not available on the same basis due to a change in land use change methodology which took effect from 2013-14.
The most recent available percentages of new residential addresses created that have been within Environment Agency flood zone 3, broken down by local authority area are provided in the attached table.

Although National Flood Zone 2 is a stand-alone category, to be practically useful it is generally combined with National Flood Zone 3 to give a complete picture of areas at 0.1% or more risk of flooding in any given year. Therefore figures are provided for National Flood Zones 2 and 3 combined.
