MMRDA was established for implementation of the Regional Plan and for Planning, Development and Co-ordination of Development within the Mumbai Metropolitan Region (MMR) . The Mumbai Metropolitan Region was delineated and the first Regional Plan for MMR was sanctioned in 1973. After considering various planning aspects, the Authority prepared the revised Regional Plan for the period 1996-2011 which was sanctioned by the State Government on 23rd September, 1999 and it came into force with effect from 1st December, 1999.
Following the 74th Constitutional Amendment, the function of Metropolitan Planning is assigned to the Mumbai Metropolitan Planning Authority (MMPC) and MMRDA is to assist in this task. As directed by the MMPC, the third draft Mumbai Metropolitan Regional Plan, 2016-36 was prepared and published for inviting suggestions and objections from the public on 19.09.2016. Following the procedure laid down under the MR&TP Act, 1966, based on the suggestions & objections received and the Planning Sub-Committee's report, MMRDA submitted the modified draft Regional Plan to the Mumbai Metropolitan Planning Committee on 30.10.2017 for its approval and onward submission to the Government of Maharashtra for sanction.
