San Francisco's parklets (left, from top to bottom: #1, Valencia Street, #2 and #3 Divisadero, and #4, Castro and 17th, bottom) are a vibrant testimony to the city's Pavement to Parks Program, managed by a non-profit, the Great Streets Program. The city's 15 parklets all started with two to three parking spaces, or other poorly-utilized urban space (the city says 25% of its space is taken up by streets or auto rights of way, while only 20% of the city is parkland--still one of the highest totals in the nation). With the help of architects, artists and landscapers, the asphalt is converted into living, breathing social settings.
The parklets do continue to provide parking space for the non-polluting form of transit: bicycles. I took a cycling tour this weekend of the city's parklets, which offer cyclists a safe and convenient place to park their two wheels and take a rest with their steed.
In the Valencia parklet (top photo), which included edgy canopy steel structures, I counted 19 people hanging out, and 31 bicycles parked. The space was much livelier, more functional and attractive than any three cars could have ever been in the same space.
San Francisco is now analyzing the numbers, behind its parklets, which were started in 2010. The analysis includes the number of users, maintenance costs, and neighborhood economic benefits.
The City by the Bay admits it was inspired by New York City's public plazas, just as it confessed using Bogota's Sunday car-free streets Ciclovia concept for its own Sunday Streets program.
Imitation is of course the sincerest form of urban innovation these days. The beauty of such experimentation is that it can be adapted for local conditions, including climate, public tastes and zoning.
The Pavement to Parks program is one of the most exciting deployments in the trend of enabling reduced urban dependency on cars, while fostering artistic and nature-enhanced community. There are other major trends portending that the future of cities (and suburbs) is beyond cars: the increase in mixed-use zoning, transit-oriented development, car sharing and light rail.
To wit: adaptable use of public spaces has become a key indicator of urban resilience. (Photos by Warren Karlenzig: click on each photo for larger format view)

I was quoted in the lead article by Michael Totty in Monday's Wall Street Journal on "How to Build A Greener City." The article (and quote) leads off a special section, including the following articles:

  • An Apple Tree Grows in Suburbia
  • The Urban Quest for Zero Waste
  • Testing Their Metals (on reducing industry material use)
  • Building Owners Want Water That Never Leaves
  • Power Play: GE Makes Big Bet on Little Firms
  • In Fracking's Wake
  • Talking About Waste With P&G
  • Cities as Ecosystems a Fresh Look
  • Reduce Energy Usage at Home
