What is a Flood Risk Assessment?
A Flood Risk Assessment is a document which identifies whether the site in question could be susceptible to flooding at present or as a result of future development. It will also determine if any proposed development could cause a risk of flooding to neighbouring properties or areas downstream of the site. A Flood Risk Assessment is a vital part of most Planning Applications.
Preparation of Flood Risk Assessments in accordance with National Planning Policy Framework, Flood Risk Standing Advice includes the following processes:
Obtaining historical or modelled flood level data from the Environment Agency.
Identifying risk of flooding from fluvial sources
Identifying the risk of flooding from local drainage infrastructure inadequacies.
Indentifying flood routes for extreme storm events above the 1 in 100 event.
Negotiations with Environmental, Planning and Drainage Authorities.
Do I need a Flood Risk Assessment?
The local planning authority will generally advise whether or not a Flood Risk Assessment is required, either in consultation with the Environment Agency or in accordance with their own policies.
However, as a general rule; if your site is within Flood Zone 2 or 3 you will need a flood risk assessment. If it is outside these zones you may still need one, particularly if the development is over 1ha or in close proximity to a river or other watercourse.
