Public Space 'Stickiness' Predicts Social Life
-
First Parklet Grew From A Two-Hour Guerrilla Experiment
- Blaine Merker and friends converted a metered downtown parking spot into San Francisco's first parklet in 2005 as a two-hour guerrilla park experiment.
- They unloaded real sod, a 20-foot box tree, and a bench, watched office workers gradually sit, take off shoes, and gather, sparking broad interest and a how-to manual.
Turn Temporary Projects Into Replicable Templates
- Create open-source templates and clear values to spread civic interventions widely.
- Blaine published a how-to manual, urged generosity and inclusivity, and worked with city officials to create a formal Parklet permit pilot.
