The objective of this report is to disclose additional information related to the data that the Federal Emergency Management Agency (FEMA) relied on in its February 2008 decision to approve Comal County's (County) Hazard Mitigation Grant Program (HMGP) application. This report supplements our audit report, FEMA Hazard Mitigation Grant Program Funds Awarded to Comal County, Texas, DD-12-13, dated June 21, 2012, and provides additional information demonstrating that FEMA based its approval of the County's HMGP pplication on incomplete information. The Texas Division of Emergency Management (TDEM), a FEMA grantee, submitted the County's HMGP application to FEMA for funding following Hurricane Rita. In February 2008, FEMA approved the County's $7 million ($5,250,000 Federal share) initial HMGP request to construct a drainage improvement structure to mitigate future flood losses. In December 2010, FEMA approved an additional $9,302,516 for the project because of a design flaw in the County's original engineering plan, bringing the total award for his project to $16,302,516 ($12,226,887 Federal share).
