The tree, which fell on Potrero Avenue near San Francisco General Hospital and Walgreens, split at the 12-foot line with two-thirds of the tree above the break, fire officials said.
The San Francisco Department of Public Works has been notified and police are on their way to the scene, according to fire department officials.

A large Douglas Fir damaged a San Rafael home Friday afternoon after it came crashing down on the roof.
Sarah Wescott stood on her street in Lucas Valley looking on in amazement as large crane pulled a 100-foot-tall Douglas fir tree off her roof.
"I was home studying for a big exam, sipping on tea when I heard the strong gusts of wind and then heard a thud, thud crash," said Wescott.
The tree landed above her daughter's bedroom, but no one was injured.
Mike Queirolo of Treemasters, the company hired to remove the tree, said another one had come down just a mile away.
"Looks like we've had 50-60 mile per hour gusts and if the wind keeps up we'll get more calls," said Queirolo.

A delay program at the airport went into effect at 9 a.m. and will be in effect until 10 p.m., Walsh said.
