Underground archival vaults with high survival rates cost between $2,000 and $4,500. The committee favored storing the capsule above ground inside a public municipal building such as the library, Community House, or Flagg School. Outcome: The working group will present a final recommendation and budget for an above-ground capsule at the September meeting.
