The new Olympia city hall sits on the Downtown Safeway site.  It is located at 601 4th Avenue East in Olympia and owned by the City of Olympia (city).

Beginning in the early 1900s, the site housed stores, a restaurant, an automobile manufacturing and painting business, automobile repair shops, and a gas station. When the city bought the property in 2007, it housed a former Safeway store, a former retail building, a restaurant, and a parking lot.  
The city's investigations found soil and groundwater contaminated with pollutants including petroleum hydrocarbons, Trichloroethylene (TCE), carcinogenic polycyclic aromatic hydrocarbons (cPAHs), and Benzene.

You can read more about contamination in the Remedial Investigation and Feasibility Study report. For more background documents, select "View Electronic Documents" in the bar on the right.

From 2008-2009, the city cleaned up much of the site while building the new city hall. The city:

  • Removed debris, free-floating contaminants, and 39,742 tons of contaminated soil.
  • Placed a liner to keep off-site contaminants from entering the site.

You can read more about that cleanup work (interim action) in Appendix D of the Remedial Investigation and Feasibility Study report (see above).

During 2013, the city monitored groundwater for one year to make sure no contamination remains above state cleanup levels. An environmental covenant now prohibits activities that would disturb the liner or contaminated soil in the Chestnut Street right-of way. You can read more about final cleanup in the cleanup action plan.

From March 28 - April 28, 2014, Ecology held a public comment period on removing the site from the Hazardous Sites List. We did not receive any commentsand are removing the site from the Hazardous Sites List.
