CHENNAI: Residents can soon expect improved proximity to workplaces, more housing choices, and enhanced civic infrastructure. The Chennai Metropolitan Development Authority (CMDA) is developing its third master plan, which will propose increased Floor Space Index (FSI) in key areas, mixed-use developments, and gradual upgrades to support compact, vertical city growth.
The upcoming master plan aims to reshape Chennai’s skyline by boosting FSI in strategically identified zones such as metro corridors, entertainment hubs, commercial centers, and industrial zones to encourage vertical development.
“We need to optimize urban space. Strategically increasing FSI near metro stations, shopping malls, green spaces, and industrial districts will allow more individuals to live closer to their workplaces and transit, maximizing existing infrastructure,” stated a CMDA official.
Additionally, CMDA plans to enhance underground amenities to facilitate vertical expansion. “We recognize that elevating FSI without corresponding infrastructure upgrades—particularly regarding sewage, water supply, and transportation—could overload already strained civic services. We recommend phased utility enhancements based on infrastructure capacity,” the official explained.
Another vital element is integrating slum communities into the urban framework. With around 40% of Chennai’s population residing in informal settlements, experts assert that the master plan must prioritize in-situ redevelopment over mere relocation.
“This involves increasing FSI in legally recognized slum areas, establishing job connections, and creating essential social infrastructure. We must address their needs to ensure dignity and maintain their social fabric, rather than relocating them away from their communities,” the official emphasized.
There’s also a push to reconsider land use strategies. Planners advocate for a more adaptable land use map that reduces agricultural zoning and increases mixed-use zones to reflect changing urban dynamics. This flexibility would streamline the currently bureaucratic land use alteration processes.
K P Subramanian, an urban planner, welcomed the idea of flexible land use zoning. “The second master plan has over 10 designated land use zones, which makes it rigid. Simplifying to a few categories—such as urbanizable, conservation, and hazardous—could make the master plan more development-friendly,” he stated.
He added that a cautious approach to increasing FSI is necessary and entails thorough studies to align with infrastructure capabilities. “The first and second master plans aimed to decentralize the city and its core business district by proposing six urban nodes and four new towns. This strategy remains relevant today,” he remarked. “Key to the success of this plan will be effective collaboration among various agencies, fostering ownership of the master plan by all involved,” he concluded.
CMDA Minister P K Sekarbabu noted that the master plan is set to be implemented on schedule.
