East Marlborough Township comprises approximately 15.5 square miles. The township contains commercial, retail, and residential uses at varying densities, mostly situated along the main transportation routes. 38% of the Township is under conservation easement, and there are significant areas of agricultural uses exhibiting lower development density — these areas are located mostly in the western and northern portions of the Township adjacent to Newlin and West Marlborough. The Village of Unionville is a focal community feature of the Township and is a focal point of the surrounding area.
Arguably the township's most significant historic structure is "Cedarcroft," circa 1859, built by Bayard Taylor, a nineteenth-century poet and writer of some note, especially for his travel journalism.
