Chennai & GCC glossary

We use these terms consistently across news and hubs. They are for reader orientation, not legal cadastral or jurisdictional advice.

GCC (Greater Chennai Corporation)

The Greater Chennai Corporation is the civic body governing the core Chennai city limits. Residents use it for property tax, waste services, road cuts, and storm-water complaints — always cross-check ward numbers with official GCC notifications.

Greater Chennai

Editorial shorthand for the continuous urban region we cover — typically Chennai Corporation limits plus key suburbs and corridors (OMR, GST Road, parts of Kanchipuram/Tiruvallur adjacency) depending on the story. It is not a single legal boundary.

OMR (Old Mahabalipuram Road)

The IT and residential corridor from Madhya Kailash toward Mahabalipuram. Traffic, metro construction, and lake catchments here often differ from core-city GCC narratives.

CMRL (Chennai Metro Rail Limited)

Operates Chennai Metro. Service changes, station access, and construction diversions are announced by CMRL and city traffic police — verify before commuting.

GCC zone (planning reference)

GCC sometimes groups wards into numbered zones for administration. Zone numbers in press releases may not match older resident mental maps — confirm against GCC ward lookup tools when filing complaints.
