In July 2018 the States of Jersey commissioned a study to develop a Shoreline Climate Resilience Management Plan. This includes flood modelling, assessment of flood risk and production of flood risk maps covering the whole Island. This is a 15 month project and the flood risk information will be used to inform policy making and emergency planning. The flood risk maps will be made upon project completion.
