Historic Boulder was born following a battle to save precious pieces of Boulder’s past. Highland School, the Union-Pacific Depot and Central School were all threatened with demolition in 1971. Historic Boulder, organized in 1972, was instrumental in saving Highland School (shown at right) and the depot. Sadly, Central School was demolished. Out of this experience rose the urgency for a legal mechanism to evaluate historic sites. In 1974 Boulder’s Landmarks Preservation Ordinance was passed and, shortly after, the inventory of significant sites began. A county regulation allowing the landmarking of sites in Boulder County passed in 1992 and was the first regulation of its kind in Colorado.
