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.; References: en.wikipedia.org/wiki/Greater_Chennai_Corporation · wikidata.org/wiki/Q3520047
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.; References: en.wikipedia.org/wiki/State_Highway_49A_(Tamil_Nadu)
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.; References: en.wikipedia.org/wiki/Chennai_Metro · wikidata.org/wiki/Q1070105
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.
