Since the early 20th century, the section of unincorporated Charleston County that later became the city of North Charleston had been designated by Charleston business and community leaders as a place for development of industry, military and other business sites. The first industry started in this area was the E.P. Burton Lumber Company. In 1901, the Charleston Naval Shipyard was established with agreements between the federal government and local Charleston city leaders. Shortly thereafter, the General Asbestos and Rubber Company (GARCO) built the world's largest asbestos mill under one roof.
