Hazard
Landslides
Relatively rapid downhill movement of a mass of soil, rock, and other debris.
Relevant Options
Incorporate information on bridge and road vulnerability to erosion, flooding and landslides into capital improvement planning processes.
Develop or update the jurisdiction's landslide study to reflect current and projected climate conditions.
Ensure backup power is available at facilities that serve vulnerable populations.
Implement monitoring mechanisms or procedures (e.g., visual inspection, electronic monitoring systems) in landslide hazard areas.
Collaborate with state resource management agencies and partner institutions to map landslide risk along transmission line rights-of-way and critical access roads. Include research on the effects of heavier
Assess the potential impacts of landslides on emergency response using detailed data and research for roads, parcels and access points. Include an assessment of options for secondary access in landslide-prone
Use vegetative cover to help stabilize slopes, reduce slope failure and minimize waterbody sedimentation.
Facilitate affordable housing options outside high-risk areas for all residents.
Partner with businesses on long-term recovery.
Coordinate with regional transit providers to identify alternative routes and stops if normal infrastructure is damaged or closed as a result of extreme events.
Work with local planning departments to establish setback requirements that help prevent or prevent impacts from erosion or landslides. Use large setbacks
Create a plan for timely clean-up pre- and post-event to avoid impacts on natural areas and water bodies.
Create and invest in strategic pre-disaster plans for post-disaster recovery.
Prepare geohazard designation mapping. Use these maps to update zoning codes and building regulations.
Purchase backup generators for the water infrastructure system to provide a sustained minimal level of water services in the event of a catastrophic power loss.
Assess governmental assets' exposure to erosion, extreme heat, flooding, high winds, landslides, severe winter weather and wildfire. Determine if those assets house critical functions. If they do, determine
Use a detailed analysis of landslide susceptibility when considering infill and development proposals. Consider the impacts of upslope and downslope debris flow pathways using shallow translational slopes
Set money aside to address hardening roads against landslides and erosion.
Develop a local funding mechanism (e.g., gas tax or tax increment financing) to provide dollars towards non-capacity transportation projects.
Revise the community's steep slope ordinance to add other metrics beyond elevation and slope, such as density, land disturbance and tree removal prohibitions.
