WSDOT ESOWSDOT operates three certified wetland mitigation banks: Moses Lake, North Fork Newaukum, and Springbrook Creek. Each bank includes a designated service area, as defined in its Mitigation Bank Instrument. These service areas outline the geographic boundaries within which WSDOT projects may apply bank credits for wetland mitigation. URL hyperlinks have been refreshed for both the Regulatory In-lieu Fee and Bank Information Tracking System (RIBITS) and the Washington State Department of Ecology mitigation bank project websites on October 24,2025.
