Council is working closely with Transport for New South Wales (TfNSW) who are providing funding to repair a number areas that were damaged in the flood events that occurred in December 2020 and March 2021, in rural locations around Nimbin and other villages.

Even though you may not see activity on the ground at the moment, there is progress being made on a number of complex flood remediation projects.

When we experience a natural disaster such as a flood event, which causes significant damage to our infrastructure, there are a number of steps that Council has to go through, which is basically like an insurance claim process. Council has to identify, assess and then make a claim for the damage from the appropriate funding body, as we do not have the money to pay for these kind of extraordinary events from our day to day budgets. in the 2020/21 financial year, Council has claimed in excess of $5.6 million in relation to flood events.

The table below provides some basic details on the status of these projects. Eight projects have confirmed funding and a proposal that has been approved by TfNSW. The estimated total value of this confirmed funding is $6,456,000. Construction on most of these projects is expected to commence in 2022. Council is currently in negotiations with TfNSW on another four projects.

    Last Thursday the majority of works on Mountain Top Road were completed. Last year, Transport for NSW approved funding to remediate flood damaged pavement on a sealed section of Mountain Top Road between Lodge Road and RH Smith Road. Although Council was hoping to stretch the budget for the full road, due to budgetary constraints the full road was not able to be completed. Patching for the rest of the road will continue this week.

    The works completed include:

    • Replacing 12 pipe drainage crossings
    • Constructing headwall and pit structures on 18 culvert outlet and inlets
    • Cleaning and reforming table drains to mitigate future damage
    • Installing rock checks to reduce velocity of stormwater in table drains
    • Reconstruction of failed embankment using 800 tonne of rock
    • Replacement of failed subgrade with geofabric wrapped rock and subsoil drainage
    • Top up road surface with additional gravel where required to correct shape
    • Stabilise overlayed material and existing pavement with lime
    • Spray seal road surface
    • Further minor surface repairs to remaining sealed section are scheduled for next week under localised traffic control

    We would like to sincerely thank the community for their patience and understanding during this project.

    Council is pleased to advise that Mountain Top road closures will be completed today from 4pm. Roadworks will continue until Wednesday 9 February under traffic light control.

    The road will be sealed next week, please drive with care and follow speed signs during this time.

    Unfortunately, due to recent weather there has been a delay in the recommencement of work on Mountain Top Road.

    Roadworks will recommence on Thursday 27 January with the road currently open under traffic light control until works begin again. This has pushed the completion date back to Friday 4 February.


    Council apologises for this inconvenience.

  • Mountain Top Road, Update & Temporary Road Closure – Commencing 12 January 2022

    Firstly, we would like to thank all residents and motorists for their patience whilst we complete the work on Mountain Top Road. We acknowledge that things are taking longer than originally expected and that residents are significantly inconvenienced by this work.

    So far, work has been undertaken to improve drainage on Mountain Top Road. The scope of works increased as failed pipes were unblocked and assessed. A landslip was also repaired using 800 ton of rock, to prevent further slipping and road damage.

    Commencing 10 January, crews will spend time excavating what are referred to as ‘pavement failures’ and replacing these with rock and gravel. This work can be done under traffic light control, to allow the road to remain open for the 10 and 11 January.

    On 12 January, we will need to revert back to full day time road closure, between 7.30 and 4pm. The work at this stage involves the importing of what’s called ‘gravel overlay’ and we have to close the road to undertake this work safely.

    On 20 January, stabilisation of the pavement will commence. In late January, the road will be sealed and it is hoped that all work will be completed by Friday 28 January.

    On weekends, the road will be open, although there may be periods of traffic light control as the overlaid gravel will require water and rolling to maintain the surface prior to sealing. The lights are on a sensor so delays should be minimised.

    In the interim period prior to sealing, the works will be exposed to possible damage from heavy wet weather. This may cause delays to the program.

    Please continue to be patient and remember to drive with care.

    We thank you for your patience while we complete this project.

    Kind regards,

    Community Engagement Team – Lismore City Council

    Council would like to apologise for the fact that we did not keep residents updated with the latest developments on Mountain Top Road. Work will stop and the road will now be open by the end of Friday 17 December. The plan is still to re-commence work on 10 January with the same road closure arrangements as we have had over the last few weeks:

    • Works will be undertaken from 6.30am to 6.30pm Monday to Friday with possible inclusion of Saturday should delays be encountered
    • The road will be closed to through traffic from 7.30am to 4pm

    The torrential rain we have been experiencing over the last 2 weeks is causing many challenges for the work that is underway on Mountain Top Road. Initial investigations also suggested that 7 drainage pipes would need replacing but it's now become clear that 12 drainage pipes will need replacing.

    More wet weather is forecast so our Engineer has decided to finish the drainage works and then cease work on Mountain Top and open the road for the Christmas period.

    The drainage works will be finished by late this week/early next week and the road will then be open on a daily basis.

    We will re-commence work on 10 January and aim to have the whole project completed by the end of January.

    We will keep you posted on any developments and thank you for your patience.

    We notified residents in August that Transport for NSW (TfNSW) had approved funding to upgrade the sealed section of Mountain Top Road between Lodge Road and RH Smith Road.

    We asked for feedback from residents to help Council decide on the best approach for the road closure. The majority of those who responded told us that their preference was for the option which involved closing the road completely between 7am and 5pm, Monday to Friday for approximately 4 weeks.

    After some delays – mainly due to COVID and its impact on availability of contractors – we are now able to go ahead with the works and temporary road closure.

    Detailed below is a brief summary of the proposed plan:

    Undertake road works from 15 November

    • Works will be undertaken from 6.30am to 6.30pm Monday to Friday with possible inclusion of Saturday should delays be encountered
    • The road will be closed to through traffic from 7.30am to 4pm – a shorter closure each day than what was originally proposed
    • Residents with properties along the restricted section will have access managed in consultation with site supervisor
    • We will work with the bus company to ensure that the school bus can get through
    • Works on road outside the full closure times will be managed under stop/go traffic control
    • Road will be fully open after 6pm each night. However, speed restrictions will be in place due to loose gravel over unfinished works. Motorists need to SLOW DOWN please.
    • The works include
      1. Replacing 7 pipe drainage crossings
      2. Constructing headwall structures on 16 culvert outlet and inlets
      3. Cleaning and reforming tables drains
      4. Installing rock checks to reduce velocity of stormwater in table drains
      5. Top up road surface with additional gravel where required to correct shape
      6. Stabilise overlayed material and existing surface with lime
      7. Spray seal road surface
    • Works are expected to take 1 month to complete excepting any delays due to adverse weather conditions

    We are currently planning for the Mountain Top Road upgrade. This means we have put out a tender for contractors which closes in w/c 27 September. Then we will work with the chosen contractors to determine their availability and start to plan the earthworks. We will notify the community as soon as we have a commencement date and will provide a reasonable amount of notice. We will also put up electronic signage at key points along the road to notify residents and motorists as soon as we have a start date.
