This is the first in the series of new growth centers that are being planned in Greater Mumbai to help arrest further concentration of offices and commercial activities in South Mumbai. It provides an alternative location where future growth of offices and commercial activity can be absorbed and where some of the existing activities from South Mumbai can be relocated.

In 1977, the MMRDA was appointed as the Special Planning Authority for planning and development of this complex. It covers 370 ha. area of once low-lying land on either side of the Mithi river, Vakola nalla and Mahim Creek. The area had poor surface drainage and was severely affected by pollution in the Mahim Creek. One of the important features of the channelisation of Mithi river and Vakola nalla was to improve water carrying capacity and reduce pollution. Mithi River for about 4.5 km. of its length from Mahim Causeway to C.S.T. Road Bridge and its tributary Vakola Nalla, for 2.5 km. of its length, have been channelised for an average 60 m. and 40 m. bed widths respectively, thereby improving the hydraulic features of these two important water courses in the BKC area.

The commercial development in BKC includes private and government offices (state and central), banks, wholesale establishments, etc. and will provide ultimately about 200000 jobs in the area. The MMRDA has so far developed 19 ha. of marshy land in 'E' Block where a number of office buildings have been constructed. These buildings together provide an office space of 174,000 sq.m. with a potential to accommodate 17,400 jobs. In this block an Urban Plaza and Park has been developed on an area of about 22500 sq.m. this park is named as CITY PARK.

Side by side the development in 'E' Block, the focus of development of activities has also moved to the adjoining 'G' Block where a new International Finance and Business Center is planned.
