Flood Risk
 |
Climate change is bringing an increased risk of flooding due to more unstable weather patterns.
In Sheffield, this means that:
- The Environment Agency's standing advice is used to determine when Flood Risk Assessments and mitigation measures are required for developments;
- In areas at risk of flooding development possibilities are constrained;
- All developments need to carefully control or reduce run-off, which can otherwise contribute to flooding locally or downstream; and
- Development will not be permitted where it would result in the loss of natural or semi-natural open space that acts as functional floodplain areas (in Woodhouse, to the south east of the city).
Sheffield’s Strategic Flood Risk Assessment (SFRA), was completed early in 2007. The SFRA collates all known sources of flooding in the city, and delineates areas that have ‘low’, ‘medium’, or ‘high’ risk of flooding. The SFRA contains a report on flood risk, and a series of maps covering the city.
Design considerations
- Has a sequential test and exception test, where necessary, been undertaken?
- Is the site in high flood risk area and what does the Environment Agency's standing advice suggest is required?
- Consider how the design can carefully control or reduce run-off.
