Each site represents one stabilization (cleaning + fencing + planting) by the PHS LandCare program. A single site may aggregate several adjacent parcels (numparcelssite). Paired with Vacant Property Indicators and 311 illegal dumping data, this is the cleanest public answer to "did intervention move the line?" — see The Vacant Block Effect.

The vacant block effect

Philadelphia has roughly 8,000 vacant buildings on the city's books and 12,000 parcels stabilized by the PHS LandCare program. They don't sit in the same places — and the 311 dumping and graffiti calls reveal whose blocks the gap leaves behind.
