When planning any development, from major infrastructure to housing you must ensure that you have an understanding of the sources and impacts of flooding. Regulations state a Flood Risk Assessment (FRA) is required for a development if it:
- includes building or engineering works in zone 2 or 3 of areas at risk of flooding from rivers or the sea;
- includes building or engineering works on land classified by the Environment Agency as having critical drainage problems;
- changes the use of land or buildings in a place at risk of flooding from rivers or the sea, or with critical drainage problems;
- changes the use of land or buildings in a way that increases flood vulnerability of the development where it may be subject to other sources of flooding; and
- is larger than 1 hectare,
In the UK the Floods of 2007 and the storms and floods of 2013/14 caused widespread flooding and damage to property and infrastructure. With the future climate uncertain, but with more extreme weather events being predicted, the need to obtain high quality flood risk information is more important than ever.
