How large is Jamaica Plain?
This answer was composed from the records listed beneath it, and from nothing else. Every statement carries the identifier of the record that supports it; every identifier was verified against the retrieved set before this page existed; and the records are named so the answer can be checked against them.
The archive records Jamaica Plain as covering 2519 acres, as bounded by the Boston Planning Department. urn:lemay:boston:entity:jamaica-plain
That is the official layer: the boundary an authority drew. What people call this place, and where they say it reaches, are filed separately as attested claims. urn:lemay:boston:entity:jamaica-plain
