A collection of Integrated High Ecological Value assets that form the natural hydrological grid across 34 Local Government Areas within the Greater Sydney Region. This data has been prepared by the Science Division of DPIE (former OEH), with input layers and support for the map provided by the NSW Department of Primary Industries-Fisheries and Department of Industry-Crown Lands and Water. Similar mapping has been prepared by OEH for the Land Use and Infrastructure Implementation Plans for the Wilton (Wilton2040, page 22) and Greater Macarthur (interim plan, page 36) Priority Growth Areas. These data packages were specifically developed for input to Local Government Local Strategic Planning Statements to support Council’s delivery of Strategy 25.1 of the Greater Sydney Region Plan.
