Conflicts and open questions

  • Acreage is given as 228 acres in some coverage and about 230 acres in the city case file.
  • The withdrawn second phase (about 128 acres east of Beecher Road) is recorded here as an event rather than a separate project because the city files present it as phase two of the same campus.
  • Coordinates are approximate, based on the Eldamain Road / Faxon Road corner described in the city file.
