Generally: The assistance FEMA provides through its PA Program is subject to a cost share (aka "match," "local match," "local share," "non-federal share"). The cost share ensures local interest and involvement through financial participation. The Federal share is not less than 75 percent of the eligible costs. FEMA may recommend an increase up to 90 percent if actual Federal obligations, excluding administrative costs, meet or exceed a qualifying threshold.
