Flood Risk and Drainage Consultants
A flood risk assessment (FRA) is a document that reviews a development in its proposal form to assess it against the risk of flooding, whether that be from groundwater, river (fluvial), surface water (pluvial), estuary/coastal (tidal), or from sewer sources. It should also take the surrounding area into account and whether the development poses a flood risk to areas nearby. Generally a scheme can be in a flood risk zone 1, 2 or 3.
An FRA is required under the National Planning Policy Framework (NPPF) and the Environment Agency (EA) guidance on development and flood risk when a development is located in Flood Zone 2 or 3, a Critical Drainage Area, or the site is greater than or equal to 1 hectare in size, for sites in Flood Zone 1.
You’ll also need an FRA if your development is taking place within 20 meters of an EA main river. EA activity permits will be required if the proposal includes temporary and permeant works within 8m of a EA river and 16m of a tidal EA river.
We provide professional hydrology consultancy and advice for many different planning applications that span the whole of the UK.
These can include standard reporting for sites within flood zone1 to more complicated reports requiring flood compensation, sequential testing, exception testing and drainage impact assessments.
