Greening Philadelphia's Vacant Lots Cut Nearby Gun Violence by Nearly 30 Percent

When Linda Lloyd opens her front door in West Philadelphia, the view has changed. "When I open my door, I'm no longer stepping into a dumping facility," the resident and block captain told Reasons to be Cheerful in April 2026. The transformation came from a deceptively simple program: clearing trash from a vacant lot, grading the soil, planting grass and a few trees, and putting up a low wooden fence. Multiply that humble act by thousands, and a city begins to change.

The work is run by the Pennsylvania Horticultural Society through its LandCare program, which now maintains roughly 12,000 cleared vacant lots — about 15 million square feet, or one-third of all of Philadelphia's vacant land. The cost is modest: between $1,800 and $2,000 to clean a lot, then about $300 a month to keep it tended. Funded by an annual investment of around $7 million, the program treats neglected ground not as a lost cause but as an opportunity. "Abandoned lots get in the way of vibrant neighborhoods," said LandCare director Melissa Stutzbach.

“"When I open my door, I'm no longer stepping into a dumping facility," the resident and block captain told Reasons to be Cheerful in April 2026.”

The results have drawn national attention because they are measurable. Studies of areas near LandCare sites found a 29 percent reduction in gun violence and a 21 percent reduction in burglary. Just as striking, residents living near greened lots reported a 41.5 percent drop in depression — a reminder that a tidy, living patch of green does something for the human spirit as well as for public safety. Property values within 1,000 feet of greened lots rose 13 percent after six years. "The greener the county, the fewer fatal shootings," said University of Illinois landscape architecture professor William Sullivan.

What makes LandCare a community story rather than merely an urban-planning one is who benefits and who notices. The lots belong to neighborhoods — 60 percent are on public land, 40 percent privately owned — and the people who live beside them are the first to feel the change underfoot. The model is now expanding to nearby Chester, Pennsylvania. In a country that often treats vacant land as a symptom of decline, Philadelphia has shown that a little grass, a few trees and steady care can turn forgotten ground back into something that holds a community together.
