Understanding the debris flood hazard, options to manage, and reduce risks to the Roxburgh community.
The next phase of the Roxburgh Debris Flood Hazard Management Programme will identify feasible options for managing debris flood hazards in the Teviot Valley. WSP consultants have completed the first stage in gathering ideas and concepts into a ‘long list’ of options.
We are coming out to present the ‘long list’ to the community. ORC and partners are gathering local ideas and feedback on the long list as the first step in a multi-stage optioneering process.
Come to our event!
If you live in the Teviot valley, please come to a drop-in session and presentation to learn more and share your thoughts.
Tuesday, 27 October 2026
Roxburgh Golf Club, 280 Scotland Street
Drop-in Session: 4:00–8:00 pm (come anytime)
Presentation: 6:30–7:30 pm
Community insights from this engagement will help to narrow down a short list of options for further consideration.
If you can’t make it in person, you'll be able to read the long-list options report and share feedback through a survey.

Hydrogeomorphic Modelling and Quantitative Risk Assessment Report. WSP New Zealand Limited (WSP) has been engaged by ORC to complete hydrogeomorphic hazard modelling and risk assessment for 13 alluvial fans that lie adjacent to the Clutha River along the base of the Old Man Range in Roxburgh. The study has been carried out in stages, and this report presents the hydrogeomorphic modelling and the findings of the risk assessment for the 13 catchments.
Julion from our Natural Hazards team reviews debris flood historical events and impacts and the pathways ORC is exploring to manage these risks.
Julion from our Natural Hazards team explains what an alluvial fan is and why debris floods occur.
