Housing: Construction

(asked on 20th June 2018) - View Source

Question to the Department for Levelling Up, Housing & Communities:

To ask Her Majesty's Government which local authorities have had the highest proportion of new homes built in flood risk areas in each year since 2010–11 for which records are available.


This question was answered on 4th July 2018

The Department produces statistics on the estimated percentage of new residential addresses created in National Flood Zone 3. Those for England for each year from 2013-14 to 2016-17 period are given in the Table 1below.

1 Land assessed, ignoring the presence of flood defences, as having a 1% or greater annual probability of fluvial flooding or a 0.5% or greater annual probability of tidal flooding.

Notes:

Areas of high risk cover approximately ten per cent of England This flood risk analysis is based on annually updated data sets of digitised boundaries provided by the Environment Agency. They reflect the river and coastal flood plains and provide indicative flood risk areas. They are areas estimated to be at risk of at least a one in one hundred chance of flooding each year from river areas estimated to have at least a one in two hundred chance of flooding from the sea. These are approximate boundaries and do not take into account any flood defences.

Figures for the percentage of dwellings built in England within flood risk areas for years before 2013-14 are given in the Table 2 below, but these figures are not consistent with the latest figures due to a change in the methodology for producing the statistics.

Areas of high risk cover approximately ten per cent of England

This flood risk analysis is based on annually updated data sets of digitised boundaries provided by the Environment Agency. They reflect the river and coastal floodplains and provide indicative

flood risk areas. They are areas estimated to be at risk of at least a one in one hundred chance of flooding each year from river areas estimated to have at least a one in two hundred chance

of flooding from the sea. These are approximate boundaries and do not take into account any flood defences. Please see LUCS statistical release for more information.

The Department produces statistics on the estimated percentage of new residential addresses created in National Flood Zone 3, broken down by local authority area, and averaged over four years. Figures for the 2013-14 to 2016-17 period are given in the attached Table 3.
