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 a long time to download over a dial-up connection (about 3 minutes per megabyte):
 

 

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:
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.
