Bureau of Mines Metallurgical Research Laboratory, Original Building, Date Street north of U.S. Highway 93, Boulder City, Clark County, NV

Significance: Building 200, as part of the Date Street Complex, was part of the Bureau of Mines Electrometallurgical Research Facility located in Boulder City. As such, it is within the designated Boulder City Historic District. One of seven buildings considered eligible, this one of two that are currently in use and will not be demolished. The building was included as a contributing element in the Boulder City Historic District Nomination (1983). Although it has undergone both exterior and interior alterations, additions, removals, the building's original footprint and roofline, as well as original roof and wall cladding, are unchanged. Furthermore, according to Pfaff the significance of the building is not associated with architecture but with the early development of Boulder City during the 1931 to 1945 period and the emergence of the Bureau of Mines Electrometallurgical Laboratory during that period, and, therefore, is is a contributing element to the District. The significance of the Boulder City Historic District is tied to the Boulder Canyon Project (Hoover Dam) and to the history of American City Planning. This was the first community constructed following the federal New Towns model, as well as the "first fully-developed experience in new town planning as promoted by the Community Planning Movement, a movement which is recognized as the force which most influenced contemporary community planning practices."
