Outram's floodbank experiences seepage during high river flows (e.g. 2017 flood).
Seepage may threaten the integrity of the floodbank in the long run. Seepage will be remediated through this project by extending 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 forms part of the Taieri Flood Protection Scheme that prevents inundation of up to 4,000 hectares of highly productive agricultural land, Dunedin International Airport, and State Highway 87.
Cost: $2 million
