What MassDEP has recorded
- RTN 3-0014595 — Fairfield St, activity and use limitation, status RAO, class A3, AUL recorded August 3, 1998 · MassDEP file
Within about 500 m (a third of a mile): 1 active tier-classified 21E site and 4 sites with an Activity and Use Limitation. All MassDEP sites in Boston.
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.
