New Oregon Map Shows Areas Prone to Landslides

PORTLAND, Or

A new landslide susceptibility map of Oregon helps identify areas that may be at risk for future landslides. State geologists say the map will help Oregonians better understand the potential hazard in their own communities. It will also help them prioritize areas for future in-depth mapping and study of landslide hazards. More than a third of Oregon's land has very high or high landslide susceptibility. Very high susceptibility means the area is an existing landslide. High susceptibility means landsliding is likely. The mapping marks the first time since the early 80s that there's been a look at the landslide susceptibility of the entire state.

"Studying landslides helps Oregon understand where taking action might decrease the risk to people, buildings and infrastructure," said Bill Burns, engineering geologist for the Oregon Department of Geology and Mineral Industries. The new landslide hazard information can also help Oregonians protect themselves and their property. State geologists say by knowing which areas are susceptible to landslides, people can identify places to avoid during extreme weather. It can also help people determine whether hiring a geotechnical professional to evaluate their property may be necessary.

Helical Pier / Installation Steps

Step 1

Excavate and prep the footing:

The footing is exposed and prepared for the bracket.

Step 2

Steel piers are mechanically "screwed"

into the soil using small construction equipment. The piers are installed to appropriate depths and capacities.

Step 3

A steel foundation bracket

is connected to the helical piers and attached to your foundation's footing.

Step 4

Perform the Lift and Backfill the Excavation:

The weight of your home is then transferred from the original, unstable soils, through the piers, to the competent soil or bedrock. The system is uniquely designed to potentially lift your home, making TerraFirma's helical piers the best solution for complete foundation stabilization and lift.
