Flights over Tomales Bay may face more stringent regulations in a few years, depending on the findings of a newly formed working group of the Greater Farallones National Marine Sanctuary. The group, chaired by Marshall resident George Clyde, includes both pilots and wildlife biologists. It will examine whether a number of sensitive wildlife areas in Marin, Sonoma and San Mateo Counties should be added to the sanctuary’s list of places where flights are subject to protections for seabirds and marine mammals, including a mandate to fly at an altitude of at least 1,000 feet.  “Every once in a while, you get an amphibious plane landing in Tomales Bay,” Mr. Clyde said. “Helicopters sometimes come low and deliver guests to Nick’s Cove. Some flights go very, very low over Tomales Bay.” Both frequent, mild disturbances and single severe events can cause seabirds to abandon colonies, leading to breeding failure, sanctuary superintendent Maria Brown said in a 2012. In 2011 and 2012, three West Coast marine sanctuaries made their overflight regulations uniform so that motorized aircrafts—including commercial planes, recreational planes, helicopters and drones—could not fly below 1,000 feet in certain areas. Below that altitude, wildlife, particularly breeding seabirds, are disturbed. (The sanctuary, which has regulated some areas, including Bolinas Lagoon, for over three decades, can grant exceptions, such as for research and during emergencies.) At the time, people advocated for the addition of Tomales Bay to the list of regulated areas, but officials said that an expansion of overflight zones would require a separate process. Mr. Clyde said the working group will meet over the next year and come up with recommendations for the sanctuary’s advisory council, which will advise Ms. Brown. The group is also considering whether other areas, like Marin’s Point Resistance and Millers Point Rocks and Devil’s Slide Rock in San Mateo, should be added to the list. Any new overflight rule would be subject to federal environmental review.
