Coastal hazard assessment

2021 Ōtākaro Avon River stopbank assessment

As part of the earthquake legacy issues project(external link), and in response to Council resolution CNCL/2019/00196(external link), engineering consultancy GHD was commissioned to complete an updated risk assessment of the stopbank from Pages Road to Bridge Street. 

The assessment found that the risk to life is low from the stopbank failing or being overtopped by water in 1 in 100-year annual recurrence interval event. The annual risk of one person dying as a result of a 1 in 100-year annual recurrence interval tide is less than 1 in 900,000.
