In a letter to Prime Minister Narendra Modi, she said her government was committed to rebuilding infrastructure and reducing the distress caused to people due to floods by providing 'gratuitous relief' for affected families.
"These costs are very large and it is very difficult for the Government of Tamil Nadu to meet the cost, particularly after the huge loss of Central tax devolution and transfers suffered by the state consequent on the 14th Finance Commission's recommendations," she said.
However, the "fourth and most severe spell" of rainfall was received after the team's visit, she said,referring to the heavy downpour on December 1,which resulted in severe flooding of Chennai, Kancheepuram and Tiruvallur districts even as Cuddalore had also been affected.
"We have now prepared the supplementary memorandum which reflects damages caused during the fourth spell of rainfall and the consequent floods in the first week of December 2015. Tamil Nadu immediately needs an additional sum of Rs 17,431.51 crore for temporary and permanent restoration," she said.

Further, during Modi's December 3 visit here, she had told him the state was preparing a supplementary memorandum to cover losses which did not find place in the earlier one and that she had sought immediate release of at least Rs 5000 crore, on account, from the National Disaster Response Fund.
Detailing about the rainfall, the CM said many parts of the state had received unprecedented torrential rains in the first week of this month, leading to a deluge in Chennai and nearby Kancheepuram and Tiruvallur districts, as well as Cuddalore, Thoothukudi and Tirunelveli.
The extremely heavy rainfall on December 1 marooned a number of localities and severely inundated lakhs of houses, she said adding in the first five days of December 2015, Chennai recorded an excess rainfall of 883 per cent, Kancheepuram 1254 per cent and Tiruvallur 863 per cent.
Roads were flooded and essential services,including trains and bus transport, were suspended in many locations, she said.
The city airport was closed for five days even as power supply had to be switched off in inundated parts of the city due to the risk of electrocution, she said.
Flood waters heavily damaged durable assets and motor vehicles in many households, she added.
However, her government had mounted 'massive rescue and relief operations immediately on a war footing,' she said.
