Geometry Type: esriGeometryPolygon

Description: The supplied data are final outputs from the Tuggerah Lakes Flood Study Review (MHL2929, 2026) prepared by Manly Hydraulics Laboratory (MHL) on behalf of Central Coast Council. The model results represent existing conditions and are based on hydrologic and hydraulic modelling undertaken in accordance with Australian Rainfall and Runoff (ARR) 2019 and the NSW Flood Risk Management Manual. The study includes simulation of design flood events from the 20% AEP through to the Probable Maximum Flood (PMF), climate change scenarios, flood hazard mapping, flood function mapping and flood planning area mapping. Results are subject to the assumptions, limitations and methodologies documented in the Tuggerah Lakes Flood Study Review report and associated mapping appendices.All content within this dataset and the associated Tuggerah Lakes Flood Study Review is owned by Central Coast Council and is protected by copyright. Reuse of the study outputs or associated datasets for purposes other than those intended by Central Coast Council may result in error and should only be undertaken with appropriate professional consideration of the report methodologies, assumptions and limitations.
