WSDOT property

102 trees were removed on Washington State Department of Transportation (WSDOT) right of way. These trees were south and west of SEA on current or future SR 509 right of way.

WSDOT administers its own standards for tree removal and replacement. WSDOT also requires that any replanting occur on WSDOT parcels. The parcels where trees were removed will soon be under highway construction. So, the Port paid into WSDOT’s tree replanting fund and WSDOT will select sites near SEA on which to replant trees. Approximately 8,000 trees will be planted on WSDOT parcels to compensate for the removed trees.
