Rachel Gordon, policy and communications director at San Francisco Public Works, gets into San Francisco’s litter puzzle. She talks trash can placement and a 2017 experiment that flooded intersections with bins. Then the conversation turns to why more cans failed, how vandalism shaped a nine-year redesign, and why street cleanliness became a civic flashpoint.

Episode notes
More Trash Cans Did Not Clean The Mission
- A 2017 Mission District pilot put cans on every corner and many mid-block spots, but more bins barely changed litter overall.
- Rachel Gordon saw some blocks improve, others stay the same, and others worsen despite cans sitting just feet from bus riders.
Street Cleaning Can Encourage More Littering
- San Francisco's litter problem is partly behavioral because people act as if street cleaning is a public maid service.
- Rachel Gordon watched drivers dump ashtrays and cups onto curbs, assuming Public Works or nonprofits would eventually remove the mess.
Trash Culture Matters As Much As Bin Count
- Trash behavior depends on local culture, not just infrastructure, which helps explain why San Francisco defies the more-cans-equals-less-litter idea.
- Delaney Hall contrasts Japan's take-it-home norm after 1995 bin removals with San Francisco's scavenging, illegal dumping, and overflowing-can complaints.
