Flood risk assessments UK are technical reports that evaluate the potential flood risks affecting a proposed development site. The purpose of the assessment is to determine whether a site may be impacted by flooding from sources such as rivers, surface water, groundwater, reservoirs or drainage infrastructure.
Flood risk assessments UK also consider how a proposed development may influence flood risk both on-site and within surrounding areas. Planning authorities require flood risk assessments to ensure developments are safe for future occupants, comply with national and local planning policies and contribute positively to sustainable development objectives.
An FRA is often required for developments located within designated flood zones or for sites exceeding specific planning thresholds. It provides evidence to support planning applications and helps inform drainage design, site levels strategies and wider infrastructure requirements.
