Presumption against development for vulnerable groups in reservoir flood areas
Development for vulnerable groups is generally not permitted within reservoir flood inundation areas due to rapid inundation risks and the difficulties certain groups face in responding to flood warnings and evacuation.
Due to the risk of rapid inundation in the event of reservoir flooding and the limitations of certain vulnerable groups to react promptly to flood warning and evacuation procedures, the policy operates a presumption against bespoke development for vulnerable groups within reservoir flood inundation areas.
