Bass Coast Shire Council Leading in Asset Management Planning for Climate Change

Council has used the Future Coasts LiDAR data to model the topology to enabled a better understanding of:• NaturalSurface• Groundwaterflows• PossibleSealevelincursion• Overlandflowpaths• Vegetation• Rural/UrbanInterfaceWSUD
Why is considering Climate Change in Asset Management important?
