What MassDEP has recorded
- RTN 3-0030648 — Concord-carlisle Hs Eastern Parking Lot, activity and use limitation, status PSC, class PA, AUL recorded November 7, 2018 · MassDEP file
Within about 500 m (a third of a mile): 0 active tier-classified 21E sites and 1 site with an Activity and Use Limitation. All MassDEP sites in Concord.
What this means
- The last deed was recorded for a nominal sum: a transfer between family members, into a trust or a similar non-market sale. It says nothing about the market value.
- An Activity and Use Limitation is a deed restriction: it limits how the land may be used (often no residential use or no digging) and passes to every buyer.
