Flood mitigation for intermittently occupied areas

Even though these areas are intermittently occupied, proposals will be required to demonstrate mitigation providing for adequate flood warning procedures and safe means of evacuation from the site. Open space areas in the undefended flood plain should be suitably contoured to avoid ponding and to allow for the quick recession of flood water. The use of synthetic sports surfaces will not be permitted where this would increase the flood risk to the site or elsewhere. It should also be noted that such materials are prone to damage through flooding.
