Flood Risk Assessment

ACCON UK is able to provide detailed Flood Risk Assessments for residential or commercial developments of any scale, nationwide. The susceptibility of land to flooding is an increasingly important consideration in determining planning applications; the potential consequences for occupiers, either of the development or elsewhere, in terms of safety and financial risk can be serious.

Flood Risk Assessments (FRAs) vary from simple exercises for small or less vulnerable developments to detailed studies for more vulnerable or larger developments sometimes requiring quantitative approaches i.e. hydraulic modelling to determine the risk posed to the development.
