A. Origin and Need

The regional plan for Mumbai metropolitan region (MMR) came into force in 1973. This plan identified Dombivali-Kalyan-Ulhasnagar-Ambarnath-Badlapur as one of the important growth areas due to industrial development in this area and due to an existing rail line connecting the area of Brihan Mumbai and other national destinations. An area south of Kalyan was also designated as ‘New Town' to integrate the growth of surrounding nuclei into an integrated urban centre.

As a recommendation of Regional Plan of MMR the Government of Maharashtra has appointed the Mumbai Metropolitan Region Development Authority established under the Mumbai Metropolitan Region Development Authority Act, 1974, (Maharashtra-IV of 1975) to be the Special Planning Authority (SPA) for the "Kalyan Complex Notified Area (KCNA)" by the Urban Development and Public Health Department Notification NoTPB-1275/1199/UD-8, dated 15th March
