About the works

  • 22/12/2022 - Four (4) tenders for the repair of thirty-eight (38) major landslip sites were received. A comprehensive evaluation process has been completed of all tenders. A report outlining the recommended tender has now been forwarded to NSW Public Work Advisory (PWA) for their endorsement. It is anticipated that PWA will have evaluated the tender acceptance report and responded back to Council mid-January. Further information can be found on the Master Project Page Severe weather events reconstruction work - 2022 | Shoalhaven City Council (nsw.gov.au)

    The August 2020 Storms and flood natural disaster event AGRN923 brought the worst flooding the region has seen in 30 years with almost 400mm of rain falling in four days and causing damages I 170 locations to Councils assets. Burrier Rd sustained various damage in 7 locations. Of this damage, there were two landslips impacting on Burrier Rd that required one lane of the road to be closed while repair options were investigated, designed and construction work tendered out

    The March 2022 AGRN1012 and the September 2022 severe weather natural disaster events event again caused significant damages across the Shoalhaven LGA including 98 landslips affecting local public roads managed by Shoalhaven City Council. Of this damage, 38 landslips were recognised as “moderate to major “and have been packed up as one large project to have the design documented by specialist consultants SLR and to be tendered out for construction by specialist contractors

    Of this package of work, four landslips are along Burrier Rd. This brings the total number of landslips affecting Burrier Rd to six (6)
