The tourism industry may be the backbone of San Francisco’s economy, but some residents have had enough.

On Wednesday, residents living near the world-famous Lombard Street will weigh in on a proposed reservation and pricing system for visitors aiming for a few moments with those Instagram-friendly red brick switchbacks.

The toll under consideration? One plan the San Francisco County Transportation Authority is considering would have a $5 toll during the week and an eye-popping $10 for holiday and weekend drivers.

It’s likely that residents of the block (and those who serve them) would be exempt from the toll, and city officials are mulling an exemption for other city residents as well. Because Lombard is a public street, San Francisco would also need permission from the state to implement the toll.

The idea has been a long time in the making. Lombard has been a tourist attraction for decades, but increased tourism over the past few years has made the situation untenable. Residents report round-the-clock gridlock on weekends. Some are concerned about crime and other quality-of-life issues, too.

Still, charging a toll to drive down a public street is an extreme overreaction to a thorny and long-standing problem.

To put it mildly, it’s an action that’s unfair and unfriendly to tourists. Despite their occasional bad behavior, the city still depends on their goodwill.

It’s also bad precedent. Many other streets and neighborhoods in San Francisco can rightly claim they have too much tourist traffic. Will the next misguided move from city government be to charge a toll to drive down each crowded block? Stay tuned.
