Landslide

Before

  • Avoid building near steep slopes, close to mountain edges, near drainage ways or along natural erosion valleys.
  • Protect your property by planting ground cover on slopes and building retaining walls.
  • In mudflow areas, build channels or deflection walls to direct the flow around buildings. Be aware, however, if you build walls to divert debris flow and the flow lands on a neighbor's property, you may be liable for damages.

During

  • Move away from the path of a landslide or debris flow as quickly as possible. The danger from a mudflow increases near stream channels and with prolonged heavy rains. Mudflows can move faster than you can walk or run.
  • Avoid river valleys and low-lying areas.
  • Curl into a tight ball and protect your head if escape is not possible.

After

  • Stay away from the slide area. There may be danger of additional slides.
  • Watch for flooding, which may occur after a landslide or debris flow.
  • Check the building foundation, chimney, and surrounding land for damage.
  • Replant damaged ground as soon as possible since erosion caused by loss of ground cover can lead to flash flooding and additional landslides in the near future.
