Tom Radulovich, the executive director of the local non-profit Livable City, describes the recent livable streets achievements in San Francisco as “tactical urbanism” — using low-cost materials like paint and bollards to reclaim street space.

That willingness to experiment was a big reason that the Institute for Transportation and Development Policy (ITDP) gave its 2012 Sustainable Transport Award to San Francisco (an honor shared with Medellín, Colombia). In this Streetfilm we profile the innovations that earned SF recognition from ITDP.

Perhaps the city’s most exciting new development has been the parklet program, which converts parking spaces into public space complete with tables, chairs, art, and greenery. These mini-parks are adopted and paid for by local businesses, but they remain public space. The concept has its roots in the PARK(ing) Day phenomenon started by the SF-based Rebar Group in 2005.

San Francisco has also seen an impressive 71 percent increase in bicycling in the past five years, despite being under a court injunction that prohibited bicycle improvements for most of that time. The city aims to have 20 percent of trips by bike by 2020. Sunday Streets, San Francisco’s version of Ciclovia, has also drawn huge numbers of participants and continues to expand.

The city has also taken the lead on innovative parking management with the SFPark program, which uses new technology to help manage public parking in several pilot neighborhoods. It aims to make it easier to find a parking spot by adjusting prices according to demand, helping to reduce pollution, traffic, and frustrations for drivers, pedestrians, and cyclists.
