Within about 500 m (a third of a mile): 9 active tier-classified 21E sites and 1 site with an Activity and Use Limitation. All MassDEP sites in Cohasset.
What this means
- Assessed 35% above the median single family residential in Cohasset ($1,231,100, 2,429 parcels).
- 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.
- Built before 1978: the Massachusetts Lead Law applies when a child under six lives there; ask for any lead inspection or letter of compliance.
