Flood Risk Assessments are area-specific or site-specific and their purpose is to ascertain the risk of flooding within the study area or site. The findings of flood risk assessments allow flood risk to be incorporated into strategic land-use decisions being made for an area as part of a development Plan or into the design of development on a particular site. AWN Consulting has significant experience in the delivery of flood risk assessments (Stage 1, Stage 2 and Stage 3) to a range of clients which include Local Authorities and private developers.
