President Obama has authorized a cost-share adjustment for Federal funds to cover 90 percent of eligible public assistance costs under the Stafford Act, which provides statutory authority for most Federal disaster response through FEMA. The cost-share adjustment, announced by President Obama in a September 8, 2016 letter to Louisiana Governor Edwards, followed FEMA’s disaster-related obligations surpassing the $621 million threshold. The adjustment amends the prior declaration of August 14, 2016, increasing the Federal cost share from 75 percent to 90 percent, and decreasing the State portion from 25 percent to 10 percent.
