In response to wet season heavy rainfall and tropical cyclone events, Townsville and the surrounding area was impacted by a range of slope instabilities including shallow slumping, rockfalls and debris flows.
PSM was engaged by Townsville City Council to assess the potential for and likely consequence of landslides on Townsville growth areas as well as roads providing emergency access and evacuation routes.
Many previous landslide occurrences had not been well documented and were frequently only verbal accounts. There was a combination of active and relict instability features and geo-hazards often occurring on steeper slopes. Assessment and mapping of inaccessible areas also had to be completed remotely.
Following our rigorous assessment, PSM’s innovative and tailored approach included:
PSM successfully provided useable landslide hazard overlay maps, potential improvements to land use planning schemes and improved response and mitigation guidelines for dealing with future landslide events.
