This includes; an experienced fish biologist to support installation and monitoring for Fish Passage Act permits; an archeologist to monitor excavation; wetland delineators; biologists to monitor bird nesting and presence; and Certified Erosion and Sediment Control Leads (CESCL) to manage Storm Water Pollution Prevention Plans (SWPPP) for the installation and maintenance of erosion and sediment control installations.
