The White House didn't say how much money may be available, but a preliminary assessment by the governor's office found $87 million in earthquake costs that could be eligible for federal reimbursement.
Funds for emergency work and the repair or replacement of facilities damaged by the earthquake is available on a cost-sharing basis for the state along with some tribal and local governments and non-profit groups, the White House said.
It broke water mains and gas lines and sparked gas-fed fires that destroyed several mobile homes. The worst damage came near the epicenter in downtown Napa, where a post office, library and a 141-room hotel were among 150 homes and buildings deemed unsafe to occupy.
Napa County has estimated overall damage from the quake at more than $400 million, much of it to the area's famed wineries.
The quake's first death did not come until Wednesday, when a 65-year-old woman died from her head injuries more than two weeks later. Scores more were injured.
