Flood street-score
A 1–10 editorial score by corridor, grounded in the August 2026 GCC monsoon map — not sensors, not tonight’s forecast.
Disclaimer: Civic guidance for residents of Greater Chennai. Official zone, ward, tax, and complaint data live on GCC and agency portals. We do not replace municipal applications or claim live complaint status. Do not treat this score as an evacuation order. Follow IMD / GCC alerts during a spell.
Editorial monsoon score from published GCC stagnation mapping (294 points; Sholinganallur 76 named). Not a live flood warning. Mayor 50 cm desk.
Sholinganallur
9/10
Mayor / GCC monsoon mapping cited 76 of 294 stagnation points in this zone — the highest named count in that briefing.
Before rain: Photograph street trenches and storm-water inlets now. Keep a dry-bag for documents.
Perungudi / OMR low pockets
8/10
IT-corridor service roads and marsh edges recur in every monsoon desk. Not a separate official count in the 294 list we have.
Before rain: Know your building plinth vs road. Don’t park in known dip points overnight when a warning is out.
Adyar / canal-edge
7/10
Canal overtopping and underpasses are a documented historic pattern; treat as high watch, not a live gauge.
Before rain: Avoid canal-edge cut-throughs during a spell. Keep the ward number for GCC 1913.
Velachery / south-west tanks
7/10
Tank-surplus and underpass flooding is a long-running Chennai pattern.
Before rain: If you use an underpass daily, have a bypass route saved offline.
North coastal / industrial
6/10
Ennore–Manali drainage and bund issues appear in civic reporting; score is editorial, not the 76-point figure.
Before rain: Check local SWD work before the NE monsoon — our Kodungaiyur / canal desks are the paper trail.
Central planned neighbourhoods
4/10
Fewer named stagnation clusters in the August 2026 briefing than the far south. Still floods at underpasses.
Before rain: Clear balcony drains. Don’t assume “Anna Nagar doesn’t flood”.
FAQ
Is 9/10 a live flood warning?
No. It is an editorial score from published GCC stagnation mapping and historic corridor patterns. For tonight’s rain, use IMD / Skymet and GCC alerts — not this page.
Where do the 294 points come from?
Greater Chennai Corporation monsoon-prep reporting quoted by our Mayor 50 cm desk (August 2026). Sholinganallur 76 was named in that briefing. We do not invent the other zone counts.
