Within about 500 m (a third of a mile): 4 active tier-classified 21E sites and 10 sites with an Activity and Use Limitation. All MassDEP sites in Somerville.
What this means
- 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.
