At the 20 May 2020 Ordinary Council meeting, Council adopted the South Cessnock Flood Mitigation Scheme which includes:
This project forms part of Council's Operational Plan. You can find it within the Operational Plan with the Project ID PMF-2022-006.
Update: 8 March 2023
The pre-construction period is complete. This period involved an independent peer review, resulting in a formal verification of the design, which satisfied grant funding requirements.
However, compulsory acquisition of Crown land for construction/drainage easement purposes has stalled due to Aboriginal Land claims affecting two parcels. This is a complex process and could cause delays to the project. To keep the project running, we are suggesting minor changes to the basin outlet (and receiving watercourse) to avoid these two properties.
Consultants are already working to determine the design implications for the potential changes to the basin outlet and will complete the assessment by April 2023. All other components of the scheme will remain the same.
A landscape architect was engaged as part of the detailed design process to enhance visual amenity for the main scheme components, being the bund wall and the diversion channel.
The tender period will commence in April 2023 provided the alternative design is accepted.
Council has now engaged the NSW Public Works to project manage the tender and construction phases, as well as to assist Council in the finalisation of pre-construction activities.
The construction period is expected to commence by September 2023.
The project is scheduled for September 2023 – February 2025.
$5,955,000 various grants and Council funds.
The project will be completed in 3 stages:
South Cessnock has a history of flooding that has been made worse by mine subsidence of up to one (1) metre in the 1980s. In a 1 in 100 Annual Exceedance Probability (AEP) flood, 16 homes experience over floor flooding and 71 homes experience yard inundation.
The bund wall will create a storage basin to detain and slowly release flood waters, thereby mitigating the impacts of flooding in the South Cessnock area. The project also involves raising five (5) homes that would still be at risk of over floor flooding in a 1 in 100 AEP event.
Benefits of the scheme include:
Yes, When completing stage-2 and Stage-3. This is something to be determined during the construction phase.
