The bill has nearly tripled in the Hurricane Michael recovery and clean up efforts across the state of Georgia.
Governor Nathan Deal announced the new total was up to $270 million Thursday.
"We have been reviewing on a financial basis what the magnitude of that special session should address," said Deal. "I know the figure of $100 million had been sort of a ballpark figure, it is determined now that that is far too small."
Deal said the call for a special session would be finalized Friday, with the session planned Tuesday.
"I will be working with the leadership of both bodies and letting them take a close look at the details of what that call is going to look like, and then that information will be disseminated to the members of the general assembly as we approach the beginning of that session next Tuesday."
The governor made his comments at a press conference Thursday at the State Capitol alongside former Secretary of State and Republican gubernatorial candidate Brian Kemp.
After a turbulent election Tuesday, Kemp declared victory Wednesday over Democratic opponent Stacey Abrams, however Abrams has refused to concede until all of the ballots are counted.
Meanwhile, Kemp resigned as secretary of state Thursday and former Georgia Department of Human Services Commissioner Robyn A. Crittenden was sworn in as the interim secretary of state that day as well.
