Climate resilience + transit-led intensification
New trajectory for fast-growing region
The Third Master Plan for the Chennai Metropolitan Area, in preparation by the Chennai Metropolitan Development Authority (CMDA) during the 2020s to succeed the Second Master Plan of 2008, is the statutory development plan for one of India's largest and fastest-growing metropolitan regions, covering a greatly enlarged planning area. Its stated orientation combines climate resilience—shaped by the 2015 floods and recurring water crises—with transit-led intensification around the metro and suburban rail network, alongside economic clustering and housing strategies for a polycentric region.
The plan is significant as a test of whether Indian statutory master planning, often criticised as rigid and slow, can absorb climate adaptation and transit-oriented principles at metropolitan scale. Chennai's experience of flood and drought has made the plan a reference point in South Asian debates about blue-green infrastructure, wetland protection and the governance of sprawling, multi-jurisdictional city-regions.
