San Francisco's Proposition B, which requires voter approval on future waterfront development projects that exceed current height limits, won easily at the ballot box Tuesday.

City voters approved the measure, 59 percent to 41 percent, with all of the precincts reporting Tuesday night.

In an election season that generally failed to capture the interest of voters, Prop B was one of the few hot-button issues on Bay Area ballots. That's because any proposed development along city's gorgeous waterfront inflames passions.

Prop B gives voters the final say on any development on port-owned land, along about a seven-and-a-half-mile stretch of the waterfront, that exceeds current height restrictions.

The measure had a populist appeal and was backed by limited-growth advocates, including former mayor Art Agnos, who said it would help ensure that the waterfront doesn't become walled off by projects intended for the rich.

But critics had argued that the unintended consequences of approval would include limiting the construction of new housing when the city already is facing a chronic shortage. The port had projected that Prop B would threaten 3,690 housing units and $124 million in affordable-housing fees.

Detractors also contended that the development-by-ballot-box approach would result in nothing ever getting built along the waterfront.

Some of the sizzle in the measure evaporated when the Golden State Warriors recently announced that they were abandoning their controversial plans to construct a new arena on Piers 30-32 and instead build on a nearby inland site. The proposed waterfront arena had become a rallying point for Prop B advocates, and that sentiment clearly carried over to election day.
