The Assateague Beach Coast Guard Station station house, garage, and boathouse are part of the Assateague Island National Seashore (NS). The station house and the garage (the original boathouse) were built in 1922 when U.S. Coast Guard Station 150 was established at the southern end of Assateague Island in Assateague, Virginia. When the boathouse was constructed in 1938- 39 on Tom's Cove to the north of the station house, the original boathouse was converted to a garage. The Assateague Beach Coast Guard station was decommissioned in 1967, and the same year the site became part of the Assateague Island (ASIS) NS. Lack of park operating funds and infrequent usage of the site has resulted in increased deferred maintenance and a resulting loss of historic fabric. The buildings will require significant work that would potentially affect important features, necessitating the identification of the character- defining features to ensure the preservation of the structures' integrity, and to provide guidance for the reuse and preservation of the structures. This draft historic structure report for the Assateague Beach Coast Guard Station structures is an abbreviated Level II report. It was prepared for Assateague Island NS by the Building Conservation Branch (BCB) of the National Park Service's Northeast Cultural Resources Center. Preparation of this report began with historical and archival research, and physical and photographic documentation of the structures, which was conducted by BCB Architectural Conservators Maureen K. Phillips and John A. Scott. According to the terms of the project agreement, no fabric analysis (e.g., paint analysis, mortar analysis, etc.) was performed. The report was written by Architectural Conservator Maureen K. Phillips.
