There are nearly 1,200 yards in the Ecology Yard Program service area that qualify for soil replacement.  Ecology works on 30-50 yards a year. To date Ecology removed and replaced soil in 333 residential yards. 

The Ecology Yard Program soil replacement is a long-term project. The soil replacement sequence outlines how Ecology planned their work throughout the Yard Program Service Area. Ecology started with the yards with the highest average contaminant concentrations.

Find your letter group by entering your address into our Dirt Alert map and downloading documents found under “Soil sampling map & paperwork.” For more information on the soil replacement sequence, visit Ecology’s webpage Soil replacement for residential yards.
