We audited Federal Emergency Management Agency (FEMA) Public Assistance grant funds awarded to the City of Flagstaff, Arizona (City), Public Assistance Identification Number 005-23620-00. Our audit objective was to determine whether the City accounted for and expended FEMA grant funds according to Federal regulations and FEMA guidelines. The Arizona Division of Emergency Management (Arizona), a FEMA grantee, warded the City $3.5 million for damages resulting from severe storms and flooding during the incident period of July 20, to August 7, 2010. The award provided 75 percent FEMA funding for one large project and four small projects. The audit covered the period of July 20, 2010, to August 8, 2013. We audited the one large project (Project 12) for a total of $3.3 million or 97 percent of the award. At the time of our audit, the City had ompleted work on the large project and submitted its final claim to Arizona. However, Arizona had not completed its review of the City’s final claim; therefore, the project remained open.
