The Mumbai Metropolitan Region Development Authority has partnered with Singapore-based Surbana Jurong to design the master plan for the new 323 sq km Mumbai 3.0 urban hub in Raigad. This development, aimed at easing regional congestion, coincides with a $1.1 billion investment announcement by Mapletree for a mixed-use project in the area. Investors should note the ongoing land acquisition and potential execution risks.
The Mumbai Metropolitan Region Development Authority (MMRDA) has taken a significant step toward the development of the "Mumbai 3.0" project, formally designated as the Karnala-Sai-Chirner (KSC) New Town. On August 7, 2026, the authority signed a formal agreement with Singapore-based infrastructure consultancy Surbana Jurong Infrastructure Pte Ltd. The firm is tasked with creating a comprehensive master plan and vision document for the 323.44 square kilometer region within the next 30 weeks.
Strategic Connectivity and Development
The KSC New Town spans 124 villages across the Uran, Panvel, and Pen talukas of Raigad district. The location is selected primarily for its proximity to major infrastructure projects, including the Atal Setu (Mumbai Trans Harbour Link) and the upcoming Navi Mumbai International Airport. By linking these transportation assets with new commercial zones and logistics parks, the state government aims to create a viable growth corridor that relieves population and infrastructure pressure on the existing Mumbai and Navi Mumbai metropolitan areas.
Investment Momentum
The announcement of the master plan comes alongside significant private capital interest in the Raigad-Pen Growth Centre. Mapletree has committed to investing over $1.1 billion in a 100-acre mixed-use development within this region. For the real estate and infrastructure sectors, this large-scale commitment acts as a potential indicator of confidence in the area’s long-term commercial viability. However, the conversion of this potential into a functional economic hub will depend heavily on the timely execution of the master plan and the successful integration of residential, commercial, and transport infrastructure.
Land Acquisition and Investor Risks
Investors monitoring the region should consider the complexity of the land acquisition process. In March 2026, the state government approved a compensation policy that offers landowners options such as Floor Space Index (FSI), Transferable Development Rights (TDR), or a land pooling model involving 22.5% of developed land. While these policies aim to streamline the process, the project faces notable headwinds, including local opposition from residents and farmers' groups who have expressed concerns over displacement and compensation terms.
Furthermore, the project carries the execution risks typical of large-scale, greenfield urban developments in India. Past projects of this nature have often faced timelines that extend beyond initial estimates. Potential investors should also be aware of the risks associated with speculative land purchases, as the final zoning, land use permissions, and infrastructure rollout are still in the preliminary stages. The ultimate success of Mumbai 3.0 will depend on the government’s ability to navigate local resistance, complete land acquisition smoothly, and attract anchor tenants to the new township.
