Local Level of Significance
The Trefethen-Evergreen Improvement Association (TEIA) in Portland, Cumberland Country, Maine is located on Peaks Island in Casco Bay. The 1914-15 wood frame building was built as the Dayburn Casino, one of a handful of similar structures that dotted the Maine coast in scenic locations. The building was primarily used as a dancehall; however, largely because of World War I, the venture failed. Two years prior to the construction of the casino, residents founded the Trefethen-Evergreen Improvement Association (TEIA) with the mission of improving Peaks Island and promoting social, religious, and intellectual life. TEIA purchased the former casino as their clubhouse in 1922 and operate the membership organization to this day. The TEIA Clubhouse and adjacent lands are locally significant under Criterion A for Social History and Entertainment/Recreation. As one of the last remaining historic civic and recreation buildings on Peaks Island, the clubhouse represents both a legacy of civic involvement and improvement, and advancement of summer recreational activities for residents and visitors alike. Additionally, the building is significant under Criterion C for its type, period, and method of construction. The casino/dance hall type is identifiable by the expansive central hall which is covered by a double-pitched hip roof and surrounded by engaged wraparound porches, a stage, and various smaller support rooms. The nominated property includes the TEIA Clubhouse, and three tennis courts as a contributing structure; within the boundaries are the non-contributing ca. 1890 Sea Gull Cottage, a shed, dock system, and pickleball court, none of which contribute due to age or lack of integrity. The period of significance is from 1914 to 1973 which begins with the date that clubhouse building was built, includes the purchase dates of the clubhouse, and continues to the height of TIEA's membership in the 20th century.
