What we found walking it

Flat lawn to a salt marsh and a creek that fills twice a day. The lower third is in a flood zone and the trustees buffer leaves the upper two-thirds for the building area.

  • The marsh edge was flagged on 20 August. The trustees' buffer runs 100 ft back from it.
  • An old farm lane along the west line, firm enough to carry the construction drive.
  • Two black cherry trees near the road, worth keeping.
  • Groundwater at six feet: a crawlspace, no basement.
