🗺️ Expansion into Chengalpattu District

• On October 21, 2022, the Tamil Nadu government issued a GO extending the Chennai Metropolitan Planning Area (CMPA) from 1,189 km² to 5,904 km², incorporating 1,225 villages across four districts

• Specifically, Chengalpattu district contributed 296 villages, selected primarily from the taluks of Chengalpattu, Thiruporur, Tirukalukundram, and Vandalur

🏘️ Satellite/New Town Development Plan for Chengalpattu

• A 136.25 km² Master Plan area—covering 60 villages from the taluks of Chengalpattu, Thirukazhukundram, and Thiruporur—has been officially notified under the Chengalpattu New Town plan

• Earlier (August 2022), CMDA had identified 48 villages around Chengalpattu core as part of the strategic satellite town initiative

• The overarching goal: structured urban growth along corridors like GST Road, Chengalpattu–Thiruporur, and Chengalpattu–Walajabad, while conserving natural features like the Palar River and nearby hillocks

🚧 Why This Matters

1. Regulated Development
   Now under CMDA’s jurisdiction, new constructions need formal approval, ensuring planned layouts, environmental safeguards, and regulated land use.

2. Integrated Infrastructure
   CMDA plans include major transport projects—like modern bus terminuses and improved road networks—expected to be built with HPCS and PPP models .

3. Economic Growth & Services
   The development is part of the ‘satellite towns’ policy aimed at decongesting Chennai, encouraging local economic hubs, and improving public services—such as water, sewage, green spaces, healthcare, and education

4. Public Feedback & Compensation Rights
   Despite CMDA planning control, the 296 Chengalpattu–area villages are still legally treated as rural concerning land-acquisition compensation—benefiting landowners

🗣️ Local Sentiment

“Chennai Metropolitan Area only deals with town planning and approvals primarily… Chromepet was already in CMA. The expanded area will be brought under CMDA control instead of DTCP for planning purposes.

“Once the New Town development areas are notified, it will help us prepare separate master plans for … Chengalpattu. This will help in planned development.”
