Description: This dataset represents landslide deformation for the City of Portland Water Bureau service area and the conduit corridors leading from the Bull Run Watershed.
Data are classified into ranges. Water bodies were removed. Complete methodology for landslide deformation can be found in the accompanying memorandum report for the "Portland Water Bureau Water System Seismic Study: Landslide Deformation for M9.0 Cascadia Earthquake Map," version 2.0, 2016.

Description: This dataset represents liquefaction-induced ground settlement for the City of Portland Water Bureau service area and the conduit corridors leading from the Bull Run Watershed.
Data are classified in 0.5-foot increment ranges. Water bodies and fragments smaller than 500 square feet were removed. Complete methodology may be found in the draft report deliverable, Liquefaction and Lateral Spread Hazard, (InfraTerra, 2015), submitted to the Portland Water Bureau.

Description: This dataset represents liquefaction susceptibility for the City of Portland Water Bureau service area and the conduit corridors leading from the Bull Run Watershed.
Geologic units susceptible to liquefaction have been attributed with a ranking, consisting of four ranked suceptibility classes ranging from Low to Very High. (A model was developed to account for five classes ranging from Very Low to Very High, however, no features fell within the Very Low classification.) Those with null "LiqExpl" values have been excluded from the analysis. Water bodies were removed. Complete methodology may be found in the draft report deliverable, Liquefaction and Lateral Spread Hazard, (InfraTerra, 2015), submitted to the Portland Water Bureau.
