What MassDEP has recorded

RTN 3-0035371 — Fluid Management Systems, activity and use limitation, status PSC, class PA, AUL recorded May 16, 2023 · MassDEP file

Within about 500 m (a third of a mile): 2 active tier-classified 21E sites and 9 sites with an Activity and Use Limitation. All MassDEP sites in Watertown.

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.

Point at the centre of the assessor parcel — not a survey.
