Marine Mammal Monitors

WSF’s marine contractor, Manson Construction, is back onsite to continue work on the new ferry terminal’s berthing structures. Whenever Manson is driving new piles or removing old ones, WSF will have marine mammal monitors posted in the Mukilteo Lighthouse and on the ferries between Mukilteo and Clinton. Monitors look for orcas and other protected marine species in the area and will shut down pile driving work if any Southern Resident orcas are spotted. Monitors are on duty from 8 a.m. until dusk until about Feb. 15 only when pile driving is going on.
