Mayor Gavin Newsom helped break ground at a community garden that's part of the 'Urban Farming' project.
It's a partnership among several private groups and non-profits, which are paying for most of the seeds and supplies.
Food grown at the garden will go to the volunteers who do the work, providing them with healthy, sustainable food.
"We are seeding with money not just actual seeds the community to replenish and renew their hoods by taking these old vacant lots and putting these community gardens in," Newsom said.
The Urban Farming project is based in Detroit, Michigan. Along with food maker Kraft, it is planning to open 50 projects nationwide this year.
