The earliest project of land reclamation began in 1784. The Bombay Governor had great sea wall built to prevent flooding of low-lying areas. Government and private companies joined hands and formulated plans to recaim more and more land. In 1864, Back Bay Reclamation Company won the right to reclaim the western foreshore from the tip of Malabar hill to the end of Colaba. By the 1870s the city had expanded to 22 sq km. Bombay Port Trust built a dry dock between 1914-1918 and used the excavated earth to create the 22 acre Ballard Estate. Much later, the famous Marine Drive of Bombay was developed.
