Eurobodalla coastal hazard assessment
The presentation from the consultation sessions held in 2017 is now available:
Before reading the presentation and the Eurobodalla coastal hazard assessment, please take the time to read important information about the hazard mapping below.
The mapping has a series of lines representing plausible beach erosion scenarios:
- yellow line represents the extent of erosion from a large storm that could occur under current ocean conditions (without sea level rise)
- pink line represents the extent of erosion from a large storm that could occur under projected ocean conditions in 2050 (with sea level rise)
- purple line represents the extent of erosion from a large storm that could occur under projected ocean conditions in 2065 (with sea level rise)
- blue line represents the extent of erosion from a large storm that could occur under projected ocean conditions in 2100 (with sea level rise).
- The hazard maps are based on present beach conditions. In most cases, mitigation such as beach nourishment or engineered structures that protect assets from coastal hazards are not in place.
- The maps will be clearly marked where existing mitigation is in place and the assessment took these measures into account.
- The mapping presents a range of possible scenarios that could occur in the absence of additional mitigation.
- Residential development assessment is based on a 1% encounter probability out to the purple 2065 hazard lines.
- The blue hazard lines for 2100 are included to guide Council on strategic land use planning and infrastructure investment.
- These maps will be reviewed with the updated 'Open Coast' Coastal Management Program.
- We will again engage with affected land owners and the broader community in in 2021 to increase the understanding of the risk and determine the best management solutions for our coastline.
