When applying for planning permission in England or Scotland for any development, the planning authority is obliged to consult with a number of interested parties. The consultation process with the Environment Agency (EA) and the Scottish Environmental Protection Agency (SEPA) will determine if the proposed development is in an area that is considered to have a flood risk associated with it.
Development in flood risk areas will require the production of a Flood Risk Assessment (FRA) report. It is highly likely that the Environment Agency /SEPA will object to any planning application in flood risk areas until such time as they are satisfied that an acceptable Flood Risk Assessment (FRA) report has been prepared and that flood risk can be managed to an acceptable level for the development.
Flood Risk Assessment (FRA) reports are prepared in accordance with the National Planning Policy Framework (NPPF) formally PPS25 in England. These are government guidance documents and their purpose is to avoid inappropriate development taking place within flood risk areas.
Civil Engineering Solutions Ltd have extensive experience in the preparation of Flood Risk Assessment reports to fully comply with NPPF and can deliver FRA reports throughout England at very competitive rates.
We are able to provide both initial assessments and full FRA reports with or without modelling (as required). Flood Risk Assessment reports need to examine the available data relating to flood issues at the proposed site, and consider the likely mechanisms of flooding, including allowances for climate change and increased storminess. The following list provides a basis for the information to be considered within an FRA assessment.
- Relationship of site levels to potential flood levels and Ordnance Datum;
- Historical data research on past flooding incidents;
- Obtaining data from the EAW for river & tide level;
- Calculating 1 in 100 for fluvial, 1 in 200 for tidal and 1 in 1000 year flood levels with allowances for climate change and increased storminess;
- Modelling using ISIS, TUFLOW, InfoWorks RS or HECRAS as appropriate;
- Reviewing existing flood defence measures;
- Breach Analysis of existing defences;
- Identifying emergency plans and warning systems;
- Recommending development solutions.
The Flood Risk Assessment report details what conditions should be imposed on the development to ensure the risk to people, property and the natural environment is eliminated, reduced or controlled to an acceptable level.
