This dataset supports the Housing Approvals Reform Action Plan in meeting housing targets across the Greater Metropolitan Region. Building projects having groundwater interaction are subject to the NSW Aquifer Interference Policy assessment and environmental protection requirements. All the groundwater-related factors that must be considered as part of planning for a building development are used as input layers—acid sulphate soils risk, contaminated sites risk, groundwater works risk, water features risk, groundwater dependent ecosystems risk and groundwater systems risk—and an overall risk dataset has been created from them. The accompanying Groundwater Housing Risk Dataset method report provides a detailed explanation of the context of the overall risk layer and the analysis of the subordinate input layers.

Note: If you would like to ask a question, make any suggestions, or tell us how you are using this dataset, please visit the NSW Water Hub which has an online forum you can join.
