A major landslip with road damages on Bunkers Hill Rd March 2022
22/12/2022 - Four tenders for the repair of 38 landslips were received. A comprehensive evaluation process has been completed and a recommendation has been forwarded to Public Work Advisory (PWA) for endorsement. It is anticipated that PWA will evaluate the tender acceptance report and respond to Council mid-January. Further information can be found on the Master Project Page
03/11/2022 - Following months of geotechnical investigations, design work and tender preparation, Council is now seeking contractors to bid on the 38 landslips deemed a priority. Submissions close 6 December 2022.
Shoalhaven Area – Remediation of Multiple Slips – RFT – 10053781
10/10/2022 - Due to further landslip movement, as a result of prolonged rainfall, Bunkers Hill Road is closed to all traffic. Further, given the forecast weather, this will remain the case across the weekend. Landslip damage is being monitored by staff and geotechnical engineers. Further road closures may be required. (Exception: Residents up to mailbox number 136 - with 3 tonne load limits.
06/10/2022 - Bunkers Hill Rd is closed to all traffic immediately with the exception of residences up to mailbox number 136 due to further landslip movement as a result of further prolonged rainfall. Vehicles are being stopped from entering or leaving Bunkers Hill Road due to safety concerns. Landslip damage is being monitored by Council staff and further road closures may be required.
30/09/2022 - With rainfall forecast for the Shoalhaven, Council reminds residents that it may become necessary to close access roads previously impacted by land slips. The trigger is 40mm of rain within any 24-hour period. Council will provide as much warning as possible should this occurs. Maintaining road safety and access across the city remains Council's highest priority. Load limit on this road is 3 tonnes.
06/09/2022 - Geotechnical engineers will be conducting a site investigation on Bunkers Hill Road, Tuesday 6th September 2022. The road will be open under traffic control.
02/09/2022 - Geotechnical investigations that will inform the ultimate engineering design for the rehabilitation of the five Bunkers Hill Road landslips have been completed in early August. Design work is well progressed and is expected to be completed by end of September 2022
01/09/2022 - Following record rain events, Council has recorded 98 landslides as a high priority, with a focus on 38 sites that are deemed most urgent. We've now finished geotechnical investigations at these 38 sites, leading the way for designs to be completed in the coming weeks. The designs form part of a works package that will go out to tender in October.

In the event of excessive rainfall and geotechnical advice traffic conditions may change.
23/06/2022 - Draft designs are now complete.
16/06/2022 - Preparation works are being allocated for contractor engagement while design review process is being finalised.
09/06/2022- Final design is currently under review by the geotechnical engineer which, once complete, can be issued for construction. One lane continues to be open with load restrictions remaining at 3 tonne.
02/06/2022 - Geotechnical investigations continue on Bunkers Hill. One lane continues to be open with load restrictions remaining at 3 tonne. Design works are now underway. Load limits remain in place under supervision with our traffic control team.
26/05/2022 - Design works are now underway. Load limits remain in place under supervision with our traffic control team. One lane access remains open for residents (and guests)
13/05/2022 - Council continues to monitor the site daily and had a formal geotechnical inspection this morning. A decision was made to maintain the 3 tonne load limit as the Bureau of Meteorology is expecting that 200mm will be received in the catchment next week. Traffic Controllers will also remain in place. The next formal review will be on Friday 20 May 2022.
10/05/2022 - Due to the significant rainfall we are receiving in the northern part of the Shoalhaven Council there may be a requirement to close access to the site if rainfall triggers are reached.
