Yard Program updates

Since 2013, we've found 1,198 properties (yards) that qualify for soil replacement. To date, we've replaced soil in 325 yards within the Yard Program service area (service area).

Current progress: 2021 construction groups

In November 2021, we started construction on 25 properties in North Tacoma. This work continues our efforts to address contamination in neighborhoods outside of the EPA Study Area. These properties fall into two work areas: 

  1. Between North Frace Street and North Pearl Street, north of 45th Street and south of Park Avenue
  2. Between North Pearl Street and Orchard Street, north of 39th Street and south of 46th Street

If you have concerns about our contractors or any Yard Program construction work, let us know by calling our project line at 360-407-7688 (press 2 to reach the Tacoma Smelter Plume)

In 2022 we plan on working on 50 yards in Tacoma.

Soil replacement in 2022       

For the 2022 construction year, we're planning on soil replacement for approximately 50 properties inside and outside the EPA Study Area. We're committed to moving construction forward to the best of our ablities, and with respect to any further COVID-related disruptions. 

Soil replacement during COVID

We're taking a cautious approach to returning to our construction work in the field. All Ecology staff are vaccinated. With the help of contractors, we're able to continue our Yard Program construction work. The contractors must follow the state's coronavirus (COVID-19) job site requirements. The state requires that contractors have a COVID-19 plan on file with Ecology. The plan outlines the safety measures they will take. It outlines how they will keep their workers — and those that they are working around — safe and healthy.   

Soil sampling and soil replacement paperwork

Ecology’s Dirt Alert map puts information and data in one place. Where available, the map visually displays soil sampling data. It also provides useful links to Ecology and the Health Department’s websites and contact information.

If you would like to find out if your yard already has soil sampling or soil replacement information, enter your address in the address search. Click on "More information" in the pop-up box in the bottom, left-hand corner of the screen to find property-specific soil sampling and soil replacement information.
