The Act – Section by Section Part 3 – Flood Risk Assessment, Maps and Plans Section 23 – Flood risk maps
78.This section requires flood risk maps to show the potential adverse consequences of the floods shown in flood hazard maps. As with flood hazard maps, information on flood risk may be presented in a single map or through multiple maps.
79.Flood risk maps must show the potential adverse consequences of floods by reference to various matters listed in subsection (2). These matters include those set out in Article 6.5 of the Directive. The list of matters is not exhaustive, and the Scottish Ministers may make subordinate legislation under subsection (2)(f) requiring SEPA to show additional information in flood risk maps.
80.Subsection (3) allows SEPA to decide whether to include additional information in flood risk maps. This can be information on floods containing transported sediments and debris, other sources of pollution or any other available and readily derivable information. Floods that are caused by a sewer being overloaded by higher than usual rainfall are covered by the Act.
