A journalist looks into why California’s power blackouts have hit some suburbs but not the biggest cities:
The municipal utility that serves Los Angeles doesn’t shut off power during high winds. As the utility explained in a recent press release, the city’s miles of pavement, numerous fire stations and relatively limited open spaces help protect it from runaway fires. There’s also the chaos that could ensue from knocking out traffic lights in the capital of car culture.
L.A.’s approach, however, isn’t foolproof. The Getty fire that’s chased celebrities from their hillside homes started when a broken eucalyptus branch sailing on the wind hit a live power line owned by the city’s utility. The Los Angeles Department of Water and Power did not return a call Wednesday asking if it would reconsider its no-blackout policy as a result…
San Francisco, meanwhile, benefits from its famously odd climate. While the rest of California heats up and dries out during the summer, San Francisco shivers in a fog bank so much a part of city life that residents have given it a name (Karl). The fog typically vanishes by October, but even then, the city never gets as dry as most of its suburbs. And the dangerous Diablo winds striking this month rarely hit the city as hard as its hilly suburbs.
As a result, San Francisco isn’t included on the state’s official map of high fire threat areas. So PG&E Corp. doesn’t cut its power when winds rise, said utility spokeswoman Ari Vanrenen. That’s not to say the city couldn’t someday lose electricity if PG&E takes down a transmission line that feeds it.
These reasons make some sense. Denser urban areas are less likely to have large areas of foliage and nature in addition to exposed power lines through which fires can easily spread.
At the same time, it might be difficult to make a case when many people in the state are affected by the blackouts and others are not “sharing the burden.” Do such choices provide economic benefits to certain areas while others are hurt?
The case of Los Angeles could get pretty interesting in this regard in that there are some more natural areas surrounding the city and separating communities. The Getty fire above is a good example; the museum and the surrounding homes sit on less dense land on hillsides overlooking the city. Could a fire break out there and then end up on either side of the hills/mountains and spread to urban and suburban land?
