The Potomac Mills complex is regionally significant under National Register Criteria A and D (historic) in the area of Industry for its important role as an industrial cement mill, appended in 1829 to Henry Boteler and George Reynolds' already active grain mill, producing hydraulic cement used in the construction of the Chesapeake & Ohio Canal, regional railroads, and for public building projects in Washington, D.C. through the late nineteenth century. Now a standing ruin, the industrial complex has significant potential to yield archeological information about the hydraulic cement production process during the nineteenth century. The Potomac Mills complex gains additional significance on a local level under Criterion A as a merchant grain mill established in 1826, which purchased and processed locally-grown grains for resale in the port city markets of Georgetown and Baltimore. As both a grain and cement processing facility, the Potomac Mills was an unusual combination.
