The original 227 mapped records are preserved: 132 PSH, 31 shelters, 59 DPH-list records and 5 drug-rehab records. Newly researched harm-reduction locations already represented at the same address in the original 227 are not added as duplicate dots. Layer counts are records; multiple programs can share an address. Public CAD locations are anonymized intersections and do not identify the caller or prove a connection to a nearby program.
