What MassDEP has recorded
- RTN 3-0038030 — Parking Lot, tier classified (active), status TIER1D · MassDEP file
- RTN 3-0034274 — 450 Chelmsford Street Lowell, activity and use limitation, status PSC, class PA, AUL recorded November 8, 2017 · 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 Lowell.
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.
