Pile driving monitoring reports are the result of

• monitoring requirements developed in consultation with NMFS, WDFW, and US Fish and Wildlife
• information collected for site specific locations
• research conducted on bubble curtains, hammer cushions, and other mitigation strategies

These monitoring reports can help with site specific information when putting together Biological Assessments for projects in the same or similar areas.

Additional reports will be added as new information from our monitoring efforts becomes available.
