Flooding can occur from a number of sources such as rivers, surface water, groundwater, sewers, reservoirs, and whilst flood prevention is difficult, the effects can be reduced. Climate change is increasing the intensity of rainfall events and it is highly likely that flooding could become more widespread with more people and property at risk of a flood in the future.
Flood risk is a major factor for new development and it is addressed within UK government policies. These differ throughout the UK, and include the National Planning Policy Framework (NPPF) in England, Scottish Planning Policy (SPP) 7 in Scotland, Technical Advice Note (TAN) 15 in Wales, and Planning Policy Statement (PPS) 15 in Northern Ireland. The aim of UK Planning Policies and Local Planning Authorities is to direct new development away from higher flood risk areas, to those with the lowest risk of flooding.
Flood risk areas are assigned zones, which are designated from ‘high’ to ‘low’ risk. In England for example, the Environment Agency has three designated flood zones, with ‘Flood Zone 3’ covering areas at the highest risk of flooding, and ‘Flood Zone 1’ the lowest. If a development is to be located within Flood Zone 2 or 3, or is over 1 hectare in Flood Zone 1, then a Flood Risk Assessment (FRA) must be carried out under the NPPF.

Outline Planning Permission was granted by Harborough District Council for the erection of 27 residential dwellings on the former Shangton Care Village site in Leicestershire. However, as the Environment Agency surface water flood maps indicated a ‘high risk’ of surface water flooding to the site a Planning Condition was included which required further information and assessment of potential surface water flood risk on site.
