The South Lismore Flood Mitigation Works project involves excavating a large amount of material from the Lismore floodplain to reduce flood water levels in the CBD, North Lismore and South Lismore. Work commenced in October 2019 and is expected to take 12 months.

About the project

The project, which is funded by an $8.2 million grant from the NSW Government, involves removing 410,000m³ of soil from a 58-hectare area of land owned by Council. The land is located behind the Lismore Regional Airport and is adjacent to Caniaba Street - please see map here for more information. The dirt removed will be used to fill nearby industrial land.

What will the benefit be?

Flood modelling (Worley Parsons, 2016) suggests this project will reduce peak water levels in the CBD, North Lismore and South Lismore by as much as 100mm in a 1-in-100-year flood event. For more information please read the full report here.

By using the material from the excavation site to fill industrial land within Lismore's floodplain, we will facilitate the expansion of the South Lismore Industrial Estate and help drive economic growth in Lismore.

  • 26 June 2020: Works on track for October completion

    We are pleased to advise that the South Lismore Flood Mitigation Works project is progressing well and running on time and on budget.

    Excavation of the primary flood channel is now 98% complete and this constitutes the major component of construction works.

    In the next month, the newly filled industrial site will be capped and re-grassed, and all ancillary works should be complete by October. During the capping works, residents may notice an increase in road-based truck movements for approximately 12 weeks (weather permitting).

    Following completion of major works, there is still extensive bush regeneration works that need to be undertaken at the site, but this work will have minimal impact on residents.

    Habitat including some koala food trees were removed to facilitate this project and Council has committed to offset this loss but regenerating the riparian zone next to Hollingworth Creek and replanting the site with more than 10,000 native trees to restore important habitat for wildlife.

    All environmental conservation work will be low impact and carried out by small bush regeneration teams once construction works are complete.

    Thank you for your patience as this major project continues.

  • 1 April 2020: Work recommences after wet weather delays

    Work on the South Lismore Flood Mitigation Project will start again next week after significant wet weather delays since Christmas.

    Rain makes this site very difficult for heavy machinery to navigate and work cannot take place until the ground has dried out. This has taken some time with lots of intermittent wet weather.

    The project was ahead of schedule so this rain has not affected our completion date of October 2020.

    COVID-19 restrictions are not affecting essential services and as such Council is continuing work on this project as planned.

    Progress
    Council contractors are ahead of schedule on the South Lismore Flood Mitigation Project. Work is scheduled to be complete by October 2020 but we are hopeful of an even better result!

    Christmas/New Year break
    SEE Civil, the contractors undertaking the current bulk earthworks, will stop work from Friday, 20 December 2019 and resume work on Monday, 6 January 2020. We wish you all a safe, happy and peaceful festive season!

    Caniaba Street road closure
    The temporary closure of Caniaba Street between Three Chain Road and Casino Street will remain in place over the Christmas/New Year break and until the 12-week temporary closure period concludes in early February.
  • Caniaba Street closed to through traffic for 12 weeks

    Caniaba Street, between Three Chain Road and Casino Street, South Lismore, will be temporarily closed to through traffic from Monday, 4 November 2019 for approximately 12 weeks.

    The road closure will enable SEE Civil to deliver fill to a private landowner directly adjacent to the project site in the shortest possible timeframe. Landowners receiving fill from the site went through an extensive Expression of Interest process to qualify to receive this material.

    Closing this section of road will allow the delivery of fill to take place quicker, without the need to traffic the material via heavy vehicles on a longer, alternative route. This should speed up the project significantly and minimise the impact on local roads.

    Detours will be signposted and drivers are encouraged to use alternative routes during this time. Access to properties within the work zone will remain available.

  • South Lismore flood mitigation works underway

    Work on the South Lismore Flood Mitigation Works Project is likely to commence in the next couple of weeks with SEE Civil recently appointed the principal contractor to undertake bulk earthworks.

    The $8.2 million project funded by the NSW Government involves diverting floodwater overflow from Leycester Creek around the Lismore Regional Airport. This includes the excavation of 410,000m³ of material from a 58-hectare parcel of Council land.

    Flood modelling (Worley Parsons, 2016) suggests the project should reduce peak water levels in the CBD, North Lismore and South Lismore by as much as 100mm in a 1-in-100-year flood event. The excavated material will be used to fill nearby industrial land within Lismore’s floodplain and facilitate the expansion of the South Lismore Industrial Estate.

    Preliminary works are already underway with Council recently relocating two major sewer mains. They have been ‘bedded’ (backfilled with material to protect the pipe) using 1500 tonnes of crushed glass from the Lismore Recycling & Recovery Centre.

    “This is a great example of reusing a waste material plus there is a significant cost saving to the project from using this bedding material opposed to traditional crushed rock,” Director of Infrastructure Services Peter Jeuken said.

    “This project was endorsed by the Lismore Floodplain Management Committee and is part of a range of measures detailed in the Lismore Flood Mitigation Plan to help safeguard the community and increase disaster resilience.

    “Council and SEE Civil are consulting with affected landowners this week to ensure they are fully informed and aware of the scope of the works.”

    NSW Deputy Premier John Barilaro said the project was vital for Lismore.

    “I was thrilled to stand alongside the then Member for Lismore Thomas George earlier this year to announce $8.2 million in NSW Government funding for this vital project,” he said.

    “This is a great example of the NSW Government, Council and the community working together to get the best outcome.”

    Council is overseeing the project, but NSW Public Works Advisory will project manage the construction on Council’s behalf. Work is expected to take 12 months to complete.
