# 11-04-26 Landmarks Board Meeting

The City of Boulder Landmarks Board met on November 4, 2026. The board unanimously conditionally approved a Landmark Alteration Certificate for a 6,230-square-foot addition to the Flatirons building at the Mount St. Gertrude’s Academy landmark site. Conditions call for design revisions to reduce and articulate the building’s massing, refine the entrance, porch, dormers, and windows, consider the connector’s design and materials, and provide a tree-protection plan. Public commenters raised concerns about the addition’s scale, materials, trees, open space, drainage, and neighborhood impacts. The decision may be called up by City Council; otherwise, the revised conditions will go to the Landmarks Design Review Committee. No contract awards, vendor selections, or other procurement activity were identified.

The board also unanimously found that the Mesa Laboratory of the National Center for Atmospheric Research (NCAR) meets the criteria for inclusion on the National Register of Historic Places and recommended that the State Historic Preservation Office forward the nomination to the State Review Board. The board approved its October 7 meeting minutes, and staff noted that a separate Landmark Alteration Certificate matter concerning the bandshell boundary is scheduled for a November 19 public hearing.
