What MassDEP has recorded
- RTN 3-0000495 — Crown Colony Place, tier classified (active), status TIER1D · MassDEP file
Within about 500 m (a third of a mile): 3 active tier-classified 21E sites and 5 sites with an Activity and Use Limitation. All MassDEP sites in Quincy.
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.
- A tier-classified site is a release still being cleaned up under the Massachusetts Contingency Plan; the MassDEP file shows the stage reached.
Point at the centre of the assessor parcel — not a survey.
Data: Quincy assessor file for fiscal year 2027, via MassGIS, retrieved October 30, 2026; MassDEP sites retrieved the same day. Sources and freshness. No owner names are published.
