The success of San Francisco's 38 parklets has prompted the city to make the application process more user-friendly. To help applicants, the City is hosting an open house on March 5 at the SF Planning Department office (1650 Mission) from 6 to 8PM. Additionally, the city has developed the San Francisco Parklet Manual [PDF - 16 MB], which should make it easier to parklet applicants to navigate the permitting system.
