Pay a visit to the back alleys of San Francisco's industrial, ecological and social history with representatives from CMG Landscape Architecture, a design firm well-versed in planning for and around the city's alleys. They will lead a meandering walk through the alleys of downtown and South of Market and facilitate an open discussion on the past, present and future of the city’s small urban streets.
