We can produce a Flood Risk Assessment (FRA) for any existing or proposed development in any flood zone. Click the buttons on the adjacent map for more information on flood zones and what they mean.
Current guidance requires an FRA for all sites, regardless of flood zone, when they are larger than 1 hectare. Typically, sites in Flood Zone 1 require less detail with respect to river based flood risk and the primary concern of the Local Authority will be with respect to surface water drainage, groundwater, sewer and pluvial flood risks. Our FRAs will investigate risk from all sources and generally include a separate surface water drainage statement or strategy as an appendix.
Even within Flood Zone 1 there may be some small watercourses that have not been modelled by the Environment Agency. Furthermore, the Environment Agency flood maps are not always correct. Some areas of the UK have well defined floodplains that are accurately mapped by a combination of topography, flood history and detailed hydraulic modelling. However, in other areas the flood maps are poorly defined and based upon an inadequate understanding of topography or hydrology. In some places the flood maps are based upon historic records that may, or may not, reflect actual flood extents. In such circumstances Lumax can help you to challenge the flood maps with site specific hydraulic models. Whether the site is in Flood Zone 1,2 or 3, Lumax can identify the precise outline of the floodplain associated with features not included on the Environment Agency maps. Such modelling can be critical to identifying a solution that can facilitate a commercially viable development.
Whatever the unique flood risk circumstances of your site, Lumax can investigate the hazards, advise on appropriate mitigation and prepare an assessment which complies with the requirements of the National Planning Policy Framework.
