Brownfield inventory

Within about 500 m (a third of a mile): 1 site of the state brownfield inventory. Brownfields in Thompson.
What this means
- Connecticut taxes property at 70% of its appraised market value: the assessment $1,173,700 times the town mill rate gives the yearly tax.
- Thompson last revalued in 2024. Towns revalue every five years; between two revaluations the appraisal stays the same even if the market moves.
- The last deed was recorded for a nominal sum: a transfer between family members, into a trust or similar. It says nothing about the market value.
