Dealing with the serious floods in York in the autumn of 2000 cost the City of York Council £1.3m, it has emerged.
The 2000 floods were the worst in York since records began
Protecting properties by sandbags and other means was the biggest single expense, at £394,000.
Over £100,000 was paid to the fire service, and £41,000 to the army for the help they provided.
The council has been able to reclaim a almost half the total bill from the government. But the city still had to find £772,000 from its own resources.
Details about the flood costs come in the same week as a report published by the York Flood Scrutiny Panel which looked into how the problems in 2000 were dealt with.
It concluded that residents in some areas of the city were let down by the very agencies that should have protected them.
The 2000 floods were the worst in York since records began and the River Ouse reached a height of 17ft 8.5ins above its normal summer level.
Around 40 people were moved from their homes and two rest centres were opened in the city for flood victims.
