FEMA 489, Hurricane Ivan in Alabama and Florida: Observations, Recommendations and Technical Guidance (2005) This report summarizes the observations, conclusions, and recommendations that resulted from post-disaster assessments sponsored by FEMA in response to Florida's 2004 hurricane season. During the 2004 season, the State was struck by Hurricanes Charley, Frances, Jeanne, and Ivan. More than 10 rapid-response teams and two Mitigation Assessment Teams were deployed to document observations and provide recommendations concerning building performance under the effects of hurricane winds and hurricane-related flooding. The information presented in this report is intended to assist the States of Florida and Alabama, communities, businesses, and individuals in the reconstruction process. This information will also help reduce future wind and water damage and promote the economic well-being of the nation. FEMA
