Minute Man National Historical Park seeks archaeological review as sign-replacement designs are revised

Minute Man National Historical Park staff updated the Town of Concord Historical Commission on Phase 2 of a park-wide sign replacement project and on an associated archaeological review the park submitted to the Massachusetts State Historic Preservation Office.

The presentation, given by Margie Brown representing Minute Man National Historical Park, said Phase 1 signs are installed and that the Phase 2 work is focused on replacing and, in some cases, adding interpretive and wayfinding signs across the park. Brown said the park must advance an archaeological component of the project even as sign designs are reworked because of contract timing and federal review requirements. "Phase 1 is already complete, and the signs are installed," Brown said. She explained that the contractor initially produced several oversized designs, prompting the park to create multiple "buckets" of sign types and to extend the design contract so designers can reduce sign sizes and re-scope placements.

Commissioners pressed for details the park did not have at the meeting: exact counts of new versus replacement signs, precise locations, and which signs would require ground testing. Brown said she would provide a Concord-specific table and location maps that break out whether a sign is new or replacement and whether it sits in a town right-of-way, state right-of-way, or inside park property. Brown told the commission she has been working on a Concord-only spreadsheet and had left materials with town offices that day. "There are about 22 of them in Concord," she said regarding Concord-area signs.

Brown described the archaeological notation used in the submittal: entries marked "n" require no shovel test pits at this time, "e" means further evaluation is needed, and "y" indicates shovel test pits are required before installation. She said many entries now marked "n" reflect uncertainty about final sign size and placement rather than a definitive determination that testing is unnecessary. The park plans to submit the full package to the State Historic Preservation Office and pushed the archaeological review forward to keep multiple project strands moving.

Commissioners and Brown discussed sites such as Barrett Farm (several signs there are new) and the Monument Square area (signs are intended as replacements), how letter-height standards affect overall sign size, and the need to limit visual intrusion in historic landscapes. Brown said the Harpers Ferry Center had created initial mock-ups; after redesign some proposed signs shrank from roughly 50 inches to about 30 inches in overall height. Brown also said some proposed signs for Route 2 eastbound travelers would be new and that any Route 2 work would require MassDOT review.

The commission asked the park to meet with town engineering and planning staff, and commissioners offered to conduct on-site walks in spring before fabrication and installation. Brown said the project is funded by legacy restoration dollars allocated in 2019 under the Great American Outdoors Act and that the park is trying to maximize the available funds while producing high-quality signs.

Next steps identified in the discussion included the park supplying Concord-specific location maps and a refined sign-size spreadsheet, scheduling meetings with Town of Concord engineering and planning staff (and with historic-commission staff when designs are further advanced), and holding a site walk in warmer weather to review proposed placements prior to final archaeological testing or installation.

The commission did not take a formal vote on the park's submittal during the meeting; commissioners characterized the materials as informational and asked Brown to return with updated design and location information.
