The Federal Emergency Management Agency awarded $19 million to rebuild Louisa County High School, which suffered significant damage during the Aug. 23 earthquake and subsequent aftershocks.

 “This news could not come at a better time,’’ Gov. Bob McDonnell (R) said Thursday. “Today is the six-month anniversary of the devastating earthquake, and these funds will help Louisa County take a big step on the road to recovery.’’

 The cost to rebuild the school is estimated at $43 million. A combination of insurance and state and local funds will pay for the remaining cost of the new school’s construction.

The House of Delegates allocated $2 million to aid with construction. The Senate set aside $1 million. The two chambers still have to reconcile those differences.

 On Feb. 3, FEMA awarded $3.2 million to the county to rebuild Thomas Jefferson Elementary School.
