Flood Risk Analysis
Flooding and the location of developments have become a significant issue in recent years, and the Environment Agency are now
consulted on a statutory basis over planning applications where flooding may be an issue.
We can provide technical advice for risk analysis and assessment for new developments sites as part of any planning applications.
Flood risk analysis requires the assessment of flood levels, both historical and future, hydrology, flood defence structures,
flood escape routes, mitigation measures and local drainage capacity.
The requirements for a flood assessment are:
- location plan with new property clearly demarcated
- site plan showing existing ground levels and proposed floor levels relative to Ordnance Datum.
- cross-section of site together with river levels
- details of flood alleviation measures
- probability and magnitude of flooding
- requirement for mitigation measures, such as raising ground levels, use of flood barriers etc.
- drainage impacts, including details of any increased surface run-off and how this can be attenuated
- the source of the flooding
- details of existing information on flooding
