Local Level of Significance
The Portland Waterfront Historic District was listed in the National Register of Historic Places on May 2, 1974 for its significance at the local level in the areas of Architecture, Commerce, Transportation and Urban Planning (Community Planning and Development). On December 23, 1984 two additional properties were added to the sixty-seven originally contributing properties and the boundary expanded at both the east and west ends of the district. On March 7, 2012, the boundaries were again increased to include two additional buildings and one wharf on the south side of Commercial Street. The purpose of the current nomination is to again increase the boundaries to include one commercial building on Middle Street that was built in 1914 during the district's period of significance, ca. 1790 to 1936. This building is contiguous to the existing district, is significant in the areas of Commerce and Architecture and has the necessary integrity to contribute to the district.
