India: Integrated Urban Flood Management for the Chennai-Kosasthalaiyar Basin Project
The project will strengthen climate and disaster resilience in the Chennai-Kosasthalaiyar River basin. It will reduce the exposure of 1.9 million people to seasonal flooding by (i) improving climate-resilient urban flood protection infrastructure; (ii) enhancing urban flood preparedness of the Greater Chennai Corporation (GCC), the civic body that governs the city of Chennai, and project communities; and (iii) establishing measures for sustaining the operation and maintenance (O&M) of the stormwater drainage system in the GCC.

|Description||The project will strengthen climate and disaster resilience in the Chennai-Kosasthalaiyar River basin. It will reduce the exposure of 1.9 million people to seasonal flooding by (i) improving climate-resilient urban flood protection infrastructure; (ii) enhancing urban flood preparedness of the Greater Chennai Corporation (GCC), the civic body that governs the city of Chennai, and project communities; and (iii) establishing measures for sustaining the operation and maintenance (O&M) of the stormwater drainage system in the GCC.|
|Project Rationale and Linkage to Country/Regional Strategy||Chennai is ranked the most vulnerable to climate change among large Indian cities. The city is relatively low and flat and three major rivers traverse a coastal bowl. In 2015, severe flooding claimed more than 400 lives. The floods destroyed property and livelihoods particularly of the poor and other vulnerable groups residing next to water bodies. With rapid urbanization, the city's floodwater retention capacity is constrained and diminished. Flood risk management is inadequate due to the inappropriate urban planning, limited flood forecasting and early warning systems, and inadequate response capacity and awareness of the GCC and communities. The project reinforces pillars 2 and 3 of ADB's country partnership strategy for India, 2018-2022 by supporting inclusive urbanization and improving climate and disaster resilience.|
|Impact||Chennai City made a safe place to live in, with reduced vulnerability to disaster (City Disaster Management Plan)|
