Notice of Field Work - December 27-28

Geotechnical Fieldwork: Westwood Area

Metro contractors are preparing to conduct a series of geotechnical field tests in the Westwood area as a part of the Final Environmental Impact Statement/Environmental Impact Report (Final EIS/EIR) for the Westside Subway Extension.  This work will build on the data gathered during the Draft EIS/EIR for the project and provide further soil and seismic information along the route of the Locally Preferred Alternative (LPA).  In certain areas, noise and vibration tests will also be conducted.  Following the tests, the data will be analyzed and used to make further informed decisions about subway construction.

Crews will conduct Cone Penetrometer Testing (CPT) that will consist of a truck which advances a steel cone tip into the ground by pushing an approximately one-inch diameter steel rod attached to the cone tip. As for all borings, the work area will be scanned for utilities prior to drilling, and the upper soils will be hand augered. Parking lanes and traffic lanes will need to be coned off during work hours
