Tonight, one week after the Board of Supervisors voted unanimously against an appeal to the citywide bike plan's environmental impact report, San Francisco Bicycle Coalition executive director Leah Shahum joins Carl Anthony (Urban Habitat), Jeff Tumlin (Nelson\Nygaard), Harrison Fraker (UC Berkeley, College of Environmental Design) and Benjamin Grant (exhibition curator) for a SPUR symposium, "The Post-Carbon City: Planning for abundance in an era of dwindling resources." The discussion focuses on eco-urbanism, a movement that believes in the ideal of a green city, emphasizing sustainable construction, design, architecture, development, and transit. The symposium begins at 6pm and is $5 to non-SPUR members (free to members). SPUR is located at 654 Mission Street, btwn New Montgomery and Annie.

Expect Shahum to talk a lot about how the 34 miles of new bike lanes and more than double that amount in shared use areas help to bring San Francisco a little closer to the post-carbon dream. The bike plan had been delayed for several years by a court injunction filed by NIMBY bicycle haters over an incomplete environmental impact report (EIR). The city finally completed in June, certified by the Planning Commission, and approved by the SFMTA. The supes gunend down an appeal on August 4, clearing the way for the bike plan to become a reality. The board will vote again on final approval this evening, before the bike plan heads to the Mayor's desk.
