Flood Risk Assessments
Advice for developers about Flood Risk Assessments - what you
need to provide if your site is in a flood plain - as well as links
to other information including the Strategic Flood Risk Assessment
for the PUSH area.
Partnership for Urban South Hampshire (
PUSH
): Strategic
Flood Risk Assessment
In accordance with
PPS
25, an assessment
has been carried out on behalf of the various client authorities to
understand the flood risks associated with the development of
80,000 new homes, built to accommodate economic growth in the
region. This assessment and its associated mapping is available
through the following external link:
Site Specific Flood Risk Assessments
The Council has commissioned a number of Flood
Risk Assessments in order to understand the implications (economic,
environmental and social) of its various projects. The Assessments
aim to identify the possible effects of all options including 'do
nothing' and seek to model the changes which result over time at
the location studied.
The list below indicates the Assessments
currently available. These documents are all in
PDF format for which Adobe
Acrobat Reader or equivalent willl be required. Some will also take

Are you thinking of applying for planning permission for a new
development or the change of use of an existing property?
Does the Flood Map show that your site may be at risk from
flooding? If this is the case, it is likely that we as your local
planning authority will ask you to submit a Flood Risk Assessment
(FRA) with your planning application.
Prior to carrying out such an assessment you are advised to
contact the local Environment Agency office at Colden Common
(telephone 0870 8506 506) to discuss the
scope of the assessment required and also to establish what
information may be available.
You can access useful information about when an
FRA is required
and what it should include on the
Flood Risk Advice web site (external link). This
information, known as
Flood Risk Standing
Advice, has been produced by the Environment Agency and
describes the likely response to consultations on planning
applications, from a flood risk point of view only, based on the
following three criteria:
- Development type
- Location
- Scale or size
The submission of a Flood Risk Assessment does not
automatically mean that your development will be acceptable in
terms of the risk of flooding, either to the property itself or to
neighbouring properties. Some types of development are particularly
vulnerable to flooding and would be unlikely to gain planning
permission if proposed in an area where flood risk is very
high.
Background to Flood Risk Standing Advice
Planning Policy Statement 25
'Development and Flood Risk' (PPS25) (external link) was
released in England in November 2006. Flood Risk Standing
Advice reflects the increasing importance of managing flood risk
through the effective use of the land use planning system.
Interpreting the Flood Map for Planning purposes
PPS
25 works on
the concept of Flood Zones, which are the mapping constraint that
must be used when considering new development in England. The Flood
Map is a multi-layered awareness-raising tool and is not accurate
to the level of individual properties, and is regularly updated in
light of new information.
WARNING:
Flood Map layers showing Flood defences and
Areas benefiting from flood defences should not be
taken to imply that proposed new development in these areas is
acceptable. Data on the likelihood of flooding at any given
location, accessed via the 'learn more'
button, should not be used as the sole source
of information for planning purposes.
