Design Construction Impacts
WSDOT has delayed advertising this project for construction for one year. The delay is due to the additional wetlands impacts at Pine Street/Myra Road interchange site that require WSDOT to acquire a US Army COE Individual Permit and a Washington State DOE Wetland Certification. The permit and certification are expected to take about a year to acquire.

Environmental Impacts / Compliance
Landau and Assoicates continues to collect flow and contamination data from the wells near Pine Street.
WSDOT continues to search for sites in which we may mitigate the impacts to wetlands. Single sites of sufficient area are proving hard to find.
The Environmental Assessment (EA) is anticipated to be distributed in May. The final EA will be sent to FHWA in May or June of this year. SEPA will be complete by August of this year.
