The purpose of this nomination form is to increase the boundaries of the Eastport Historic District (NR # 82000787) in Washington County, Maine. Listed in the National Register of Historic Places in1982, the Eastport Historic District was described in the nomination as ?a cohesive grouping of 29 architecturally and/or historically significant buildings.? In addition, it noted that ?(t)he district encompasses the present commercial section which lies next to the shore where the sardine industry once flourished.? The areas of significance for the district are architecture, commerce, and industry and the listed period of significance is nineteenth and twentieth centuries. The property formerly known as the Seacoast Canning Company (later the American Can Company) at 15 Sea Street abuts the Eastport Historic District. When the district was first defined this building, which was built in 1908 to can sardines, was included within the boundaries of the proposed district. It was removed during the designation process at the request of its owner. The current owners are requesting that the district boundaries be amended to include the factory as was originally intended. The property retains a high degree of integrity of setting, location, design, association, and feeling, and a substantial degree of materials and workmanship. Inclusion of this property as a contributing resource requires no change to the existing district?s area or period of significance, or to the applicable National Register criteria.
