Inflormation from Sound Transit
Starting as early as Monday, August 19, Sound Transit plans to conduct a geotechnical boring for soil analysis in the alleyway between West SeattleBridge and 32nd Ave SW (see map for exact location). This location may shift slightly depending on the placement of underground utilities. Sound Transit is in the planning phase for the West Seattle Link Extension project. This work, along with other investigations throughout the project corridor, is necessary to plan and design possible light rail alignments to be studied in the environmental review process.
Geotechnical work also coming to SW Genesee St.

Geotechnical drilling
To study soil and groundwater conditions, a drill rig is used to bore vertically into the ground while collecting soil samples. Following the collection of soil samples, a monitoring device is installed which will be used by crews to monitor water levels on future visits. Water level readings will be taken every few months as the design phase progresses.
In accordance with all local regulations, the 4- to12- inch diameter borings will be installed carefully to avoid soil erosion and dirt or mud from leaking into surface waters, wetlands, and drainage systems.
