From sf-planning.org:
Emerging visions for public thoroughfares challenge the 20th century paradigm of automobile-centric streets. Pedestrians, bicyclists, and wild critters are all demanding their own ways to cross the city. San Francisco's "Green Connections" project seeks to integrate these new visions into San Francisco's urban grid. Join Andy Thornley (SF Bike Coalition), Peter Brastow (Nature in the City), Elizabeth Stampe (Walk San Francisco), and the SF Planning Dept.'s Kearstin Dischinger to critically evaluate these competing and complementary visions of a reconfigured San Francisco.
