This zone is also important for the conveyance of floodwater to floodplain assets during large and small flood events (environmental flow releases).Uncontrolled flood work development in this zone may have a high adverse impact on flood behaviour.Delineation of this zone also has socioeconomic benefits. Limiting flood work development in this zone will prevent flood flow redistribution, increased flood velocities and flood levels which may adversely impact on life and property.Zone A ensures that there is continuity of flow and flowpaths and assists in maintaining the overall flow distribution on the floodplain.Management Zone B (Flood storage and discharge areas for design floods)Zone B includes areas of the floodplain that are important for the temporary storage of floodwaters during the passage of a flood. The outer boundary of this zone is defined by the inundation extent of the large design flood.Zone B is important for conveyance of flood water to floodplain assets during larger flood events, such as in the large design flood.Controlling flood work development in this zone is important to manage the cumulative and local impact of works on flood behaviour.Management Zone C (Flood fringe areas for floods greater than design floods and existing developed areas) Zone C includes areas outside of the inundation extent of the large design flood and existing developed areas.Flood work development in the remaining flood fringe areas is unlikely to have a significant effect on the flood behaviour. Flood works would still require an assessment and approval to protect the health of the floodplain environment.Management Zone D (Special environmental protection zone) Zone D is an environmental protection zone taken from the Lower Gingham FMP. This zone includes a core wetland area that is highly significant. The inclusion of this zone in the Gwydir FMP is to ensure consistency with the existing floodplain management planning arrangements and flood connectivity to this area is maintained and protected.", "summary": "", "title": "Gwydir Valley FMP Management Zones 2023", "tags": [], "type": "", "typeKeywords": [], "thumbnail": "", "url": "", "minScale": "NaN", "maxScale": "NaN", "spatialReference": "", "accessInformation": "OEH Healthy Floodplains Unit and OEH Waters, Wetlands and Coasts Science Branch and OEH Native Vegetation Information Science Branch", "licenseInfo": "", "portalUrl": "" }
