NOTES
Ground surface shown was constructed from digital elevation data provided by Bechtel/Jacobs and the City of Seattle.
Elevation Datum: North American Vertical Datum of 1988 (NAVD88).
Subsurface conditions shown are generalized from soils encountered in project borings and from logs of borings previously completed for other projects along the alignment. Variations between the profile and actual conditions may exist.
Projections are taken from the southbound track alignment in areas where two tracks are present.
Potentially liquefiable zones were identified using the following criteria:
a. the factor-of-safety against liquefaction for the soil sample at the corresponding depth was found to be less than 1.0 (FS liq<1.0) using the procedures described by Youd et al., 2001, or
b. the adjacent soil samples above and below a given soil sample were both found to have FS liq,1.0 using the procedures described by Youd et at., 2001, regardless of the FS liq calculated for the given sample.
Soil in the EE(A) zone is potentially liquefiable during an earthquake of magnitude (Mw) 6.75 and having a peak ground acceleration (PGA) of 0.15g.
Soil in the EE(B) zone is potentially liquefiable during an earthquake of magnitude (Mw) 7.5 and having a peak ground acceleration (PGA) of 0.20g.
Soil in the MCE zone is potentially liquefiable during an earthquake of magnitude (Mw) 7.5 and having a peak ground acceleration (PGA) of 0.30g.
See Data Report for groundwater fluctuations.
The description of each geologic unit includes only general information regarding the environment of deposition and basic soil characteristics. See text of report for additional discussion of geologic units.
