Pontoon Construction Project
WSDOT, regulatory agencies, and tribes make commitments to protect the environment and to minimize impacts. WSDOT uses the Commitment Tracking System (a database) to ensure our projects meet these commitments.
This page contains procedures and tasks that project staff use to successfully track commitments. Chapters 490, 590, and 630 of the WSDOT Environmental Procedures Manual explains why we track commitments.
