The DJC ($) is reporting that Seattle City Light will soon initiate environmental cleanup work at the old Greyhound maintenance yard at Pontius and John across from Alley 24.
The site remediation will include demolition and removal of the building, removal of soil and groundwater, and replacement with clean fill.
The work is being done to prepare the site for a future electrical substation to serve the power hungry (hah!) South Lake Union neighborhood.
