Flood Risk Management Local Plan Districts (LPDs) are geographical areas that are designated for flood management under the Flood Risk Management Act (Scotland) 2009. These areas have been based on river catchments that can cross administrative and institutional boundaries, in some locations local edits have been made to ensure locations which are part of the same sewer catchment have not been split across LPDs. SEPA and responsible authorities use these areas for the co-ordination of flood risk management in Scotland and to develop ongoing partnership working.
