Amber Hasselbring is the instigator of a lovely effort in San Francisco’s Mission District, aptly named the Mission Greenbelt Project.

We walk on layers of history. In our neighborhoods, in our cities, there were once natural phenomena, like creeks, sand dunes, hills, and forests. Over time they were covered in farms, factories, houses, and most of all, streets. At first those streets were dirt, often thick and muddy. Around the middle of the 19th century they started to be used for railroads, both intercity, and local streetcar and cable car lines. Sometimes the shape of our 21st century streetscape is a ghost of those old train lines.

Jane Martin is a longtime resident of San Francisco's Mission District, a licensed architect, and an avid gardener. She is the founder of PlantSF, an informational website dedicated to reconfiguring the design and use of urban spaces, primarily sidewalks and to a lesser extent, residential streets. PlantSF started in 2004 after Martin had spent considerable effort establishing a sidewalk garden in front of her then-home on Shotwell between 17th and 18th Streets.
