The 1970s were a decade of steadily-rising general prosperity in Hong Kong. Additional infrastructure development was undertaken throughout these years to help cope with rapid economic growth.

In 1975 reclamation work in Kowloon Bay provided a further 8.4 hectares of new land for public roads and industrial development and an additional 6.8 hectares for the further extension of the Kai Tak airport runway. In that year alone, 25 hectares of newly-created land was added to the "land bank".

In 1978 extensive reclamation in Tap Shek Kok, near Tuen Mun, formed a new 62-hectare site for the CLP's Castle Peak power station. The same year, further reclamation work was undertaken for the Hong Kong Electric power station near Yung She Wan, on Lamma Island.
