Dunedin City Council transport delivery manager Josh von Pein said work to remove debris and build a new concrete retaining wall at the South Rd site would start before the end of the month.
The work is expected to take about six weeks and cost $160,000.
Mr von Pein said there were at least 14 crews of contractors and council staff working around the city repairing damage from both the July 2017 and February 2018 floods.
Work affecting public safety and high-traffic roads took priority but the timing of repairs also depended on contractor availability, he said.
Repairs were already under way or planned for about 50 large-scale sites damaged during the floods such as bridges, slips and earthworks, while smaller work was completed when crews moved around different areas.
