THIS HISTORIC MERCHANT MILL in the National Historic Landmark village of Waterford was built in about 1830. It has been used since the 1940s as the site of a popular annual craft fair and as a symbol of the village’s history and integrity. Constant inundation of the foundation by water from Catoctin Creek, has taken a toll on the building over many years. The first phase of the project consisted of a full historic structure report, analyzing the building’s form and condition in the light of its historic significance, and outlining a series of recommendations for returning it to the best condition for long-term preservation. The second phase, recently completed, made the structural and architectural adaptations needed to bring the recommendations to completion as a fully interpreted, safe, and engaging part of Waterford’s heritage. Actions included lowering the wheel pit to a level that would permit water to readily exit to the creek, reconstructing the massive timber hurst frame that supports the milling equipment, bringing the building up to code, and making nearly invisible improvements to the structural system.
