Advice on the Port Phillip Bay Coastal Hazard Assessment
Melbourne Water acknowledges the release of the Port Phillip Bay Coastal hazard Assessment by DEECA.
This assessment is based upon a hydrodynamic model, consistent with the modelling approach for the Western Port Coastal Hazard Assessment.
The information is being reviewed by Melbourne Water’s Flood engineers. Following review and formal acceptance, significant data processing and system changes are required to integrate this new information into existing data sets. It is anticipated that this process will take until mid-year 2024.
Until the data processing and review is complete, Melbourne Water will continue to use its current data and mapping to inform development referrals and advice.
Note that the planning for sea level rise benchmark remains at 0.8m, as per Victoria’s Planning Provisions Clause 13.01-2s and Melbourne Water’s Interim Sea Level Rise Guidelines will continue to be used to assess development referrals.
