Over 100,000 people came to San Francisco's fireworks. There were 127 toilets

First came the fog. Then the gridlock. Now, bad bathroom math is adding to the fallout from San Francisco's Fourth of July fireworks show.

Only 127 toilets were available in some of the city's prime waterfront viewing areas for the estimated 100,000 people who came to see pyrotechnics launched from the Golden Gate Bridge, according to the National Park Service.

That worked out to roughly one toilet for every 787 people.

The Golden Gate National Recreation Area said the crowds were driven by San Francisco's historic bridge fireworks display, which drew thousands of people to the Presidio despite a forecast that called for fog.

The park had 27 permanent toilets in those areas and arranged for 60 portable toilets for July Fourth. San Francisco provided about 40 more portable toilets at Crissy Field and Fort Mason, according to Joshua Winchell, chief of communications and special park uses for the Golden Gate National Recreation Area.

"These 127 toilets were not nearly enough to support our July 4 visitors," Winchell said in a statement. "We will work with the City of San Francisco and our other partners to ensure that enough bathrooms and other resources required for enjoyable park visits will be in place for future large-scale events, such as Fleet Week."

The restroom shortage is the latest problem to emerge from the city's ambitious holiday celebration, which was billed as a rare display launched directly from the Golden Gate Bridge in honor of the nation's 250th anniversary.

The show drew huge crowds to the Marina, Presidio and northern waterfront, but many spectators said fog obscured much of the display and transportation problems left them waiting for buses, stuck in traffic or walking long distances home.

The San Francisco Municipal Transportation Agency apologized after widespread delays and said the system could not handle the added demand, including 41,000 additional riders on July Fourth.

Mayor Daniel Lurie has called the transit delays "unacceptable" and said the city must fix the problems before Fleet Week, another major waterfront event expected to draw large crowds in October.

Supervisors Stephen Sherrill and Bilal Mahmood have requested reviews of the city's planning, including transit service, emergency access and the role of autonomous vehicles in the gridlock.

The bathroom shortage is now expected to be part of that assessment.

Sherrill, whose district includes the Marina, has called for a hearing before Fleet Week to examine what went wrong and what needs to change.
