|Description||The proposed Integrated Urban Flood Management for the Chennai-Kosasthalaiyar Basin Project will support the Greater Chennai Corporation (GCC)0F0F in Tamil Nadu to increase its resilience to extreme weather events by (i) strengthening urban flood protection infrastructure while recharging groundwater, (ii) improving capacity of GCC and communities on planning and urban flood management, and (iii) improving operational and financial capacity of GCC's zonal offices.|
|Project Rationale and Linkage to Country/Regional Strategy||Chennai residents and industries are increasingly vulnerable to frequent, intense, hazardous and destructive floods. Water retention capacity of the city's waterbodies is reduced through encroachment of waterways due to (i) rapid and haphazard urbanization, (ii) development without consideration of the area's hydrology, (iii) a lack of climate and disaster proof land use plans, and (iv) by clogging of drains with silt and garbage. There is insufficient capacity for flood water retention due to (i) inadequate and deteriorated flood protection infrastructure, (ii) inadequate operations and maintenance, and (iii) and weak physical linkages between water bodies. GCC and its residents are also unable to anticipate and quickly respond to flooding due to a lack of flood forecasting and early warning system.|
(i) _World-class_ cities and industrial corridors across the state developed (Vision Tamil Nadu 2023)a
(ii) Water security and reduced vulnerability to climate change in urban areas achieved (Tamil Nadu Sustainable Water Security Mission, State Action Plan on Climate Change)b
|Outcome||Climate and disaster resilience in Chennai enhanced|
|Outputs||Climate-resilient, urban flood protection infrastructure upgraded and expanded in the Kosasthalaiyar River Basin|
