We have replaced soil on a total of 21 yards on Vashon-Maury Island.  

  • In 2015 we replaced soil in 15 yards.
  • In 2014 we replaced soil in six yards.

Sampling Progress:

  • We completed our final phase of Yard Program sampling in the fall of 2016. We will continue to offer home soil testing on the island.
  • As of spring 2016, we offered sampling to 1,009 yards in the service area. We sampled 753 yards and found 51 yards that qualify for soil replacement (see map below right).  
  • In May 2015, we extended the service area north on Maury Island to include 190 additional yards (see map right).
