What is the Northwest CT Atlas?

What you'll find in each town atlas

  • Parcels and owners

    Every parcel with its MBLU, address, acreage, assessed value, and current owner — drawn from the town assessor's cards.

  • Sales and land records

    The sales history on each card: book/page, date, grantor and grantee, consideration. Linked back to the source record.

  • Planning & zoning

    Every Planning & Zoning Commission item that's named a parcel, parsed from the minutes the commission publishes.

  • Map overlays

    Open space, conservation lands, wetlands, aquifer protection, surface-water class, steep slopes, hillshade, and 1934 + 1874 historical maps.
