This Flood‑Preparedness Story Has a Twist Nobody Saw Coming — 117 Drains Built, 90 Still Awaiting
The Chennai Metropolitan Development Authority (CMDA) has finished stormwater drains at 117 of the 207 vulnerable locations identified in the Greater Coastal Corridor. The work is part of a multi‑year plan to curb flash‑flooding that has plagued the city each monsoon. Residents of neighborhoods such as Mylapore and Adyar will see water recede faster during heavy rains. Yet more than 90 sites remain without proper drainage, keeping many families at risk.
What the Numbers Reveal: 207 Sites, 117 Drains, 90 Pending
According to an official report released by the Chennai Metropolitan Development Authority (CMDA) on July 12, 2024, engineers surveyed the Greater Coastal Corridor (GCC) and marked 207 locations as flood‑vulnerable. Of those, construction crews have completed stormwater drains at 117 sites, representing roughly 56 percent of the total. The remaining 90 spots are slated for Phase II, which will begin after the monsoon season ends in November. **The longest newly built drain, a 350‑metre stretch along Mylapore
Despite Chennai receiving less annual rainfall than Mumbai, its flat coastal topography and impermeable historic districts make it far more flood‑vulnerable per millimetre of rain.
