Sound Transit On-Call Environmental Services

Various Puget Sound locations, Washington

For on-going and upcoming projects since 2005, Sound Transit has required on-call environmental services for over 20 active work orders. ESA has met Sound Transit’s needs by providing wetland and stream assessments, conceptual mitigation plans, mitigation site monitoring, culvert replacement design, visual simulations, air and noise impact assessments, NEPA and SEPA document preparation, and Endangered Species Act Section 7 consultations.

We are currently developing a wetland mitigation strategy for upcoming projects throughout Sound Transit’s three-county service area to identify workable, sustainable, and economical mitigation approaches for expected impacts from transit projects over the next 12-15 years. This effort involves building a GIS project database, and forecasting impact assumptions, mitigation requirements and guidance, and potential mitigation strategies.
