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.
- A tier-classified site is a release still being cleaned up under the Massachusetts Contingency Plan; the MassDEP file shows the stage reached.
