According to the fire department, more than a third -- 33.9 percent -- of its firefighters live in San Francisco. After that, 16.3 percent hang their hats in San Mateo; 9.9 percent live in Sonoma; 9.1 percent reside in Contra Costa; 9.1 percent call Marin home; 8.4 percent are in Alameda; 3.1 percent live in Solano; 0.9 percent live in Santa Clara; and only 0.8 percent enjoy the Napa life. All told 91.5 percent of San Francisco's 1,568 firefighters live in the Bay Area. And, should a bridge ever be disabled, 51.1 percent live in locales that won't be affected.
Of the 8.5 percent who live outside the Bay Area, there are some far-flung addresses. While firefighters must live within four hours of the city per their union contract, some of these employees may have been grandfathered in during the days of the concorde. Nine firefighters live in the gold country of Placer County and six others live in San Diego, Fresno, or Los Angeles.
But there's also more than two dozen living in Sacramento County; two in Pollock Pines (a town so remote one of its major thoroughfares is the Pony Express Trail); and seven who live out of state. These non-Californians reside in towns your humble narrator can't find on the map (Canyon Wake, Indian Trail, Post Falls (possibly Idaho), Stone Mountain) as well as Coeur D'Alene, Idaho, Las Vegas, and Portland. We're presuming that's not Portland, Maine.
