The document summarizes the efforts of the Dudley Street Neighborhood Initiative (DSNI) to address environmental problems in the Dudley Street neighborhood of Boston from the 1980s to 2000s. The DSNI was founded in 1985 and envisioned creating an "urban village" with affordable housing, community centers, gardens, and green spaces. One of their first projects was cleaning up abandoned lots filled with trash and hazardous waste. Over time, through community organizing and legal action, the DSNI was able to transform over 300 vacant parcels, address toxic waste sites, and revitalize their neighborhood.
