The Outram floodbank seeps during high river flows (such as the 2017 flood), which may threaten the floodbank’s integrity in the long run. This project extended the stopbank toe with a weighting blanket, sealing or replacing culverts, constructing bottom stormwater drains, and refilling and sealing weak zones caused by tree roots.
This floodbank is part of the Taieri Flood Protection Scheme, which prevents flooding of up to 4,000 hectares of highly productive agricultural land, Dunedin International Airport and State Highway 87.
Cost: $2 million
