Mount Wilson doesn't just hold the observatory but also transmission towers for all of the major broadcast TV stations in Los Angeles, as well as a majority of the radio stations, along with transmission towers for a large percentage of emergency responder communications and commercial transmission, such as trucking logistics.

Nothing in life is guaranteed, but in the case of Mount Wilson, it's clear they've been concentrating as much effort saving the complex as they have in making sure the fires don't reach the residential communities in La Canada/Flintridge and La Crescenta.
To get something done, a committee should consist of no more than three persons, two of them absent.
