FEMA Mitigation Best Practices: Risk MAP Success Story: The Herbert Hoover Dike Presented a Unique Challenge; FEMA Responded With a Unique Solution   [open pdf - 39KB]

"The Herbert Hoover Dike, which surrounds Lake Okeechobee in South Florida, could not be accredited to protect against the 1% annual chance flood event by the United States Army Corps of Engineers (USACE). Portions of five counties surrounding the lake - Glades, Hendry, Martin, Okeechobee, and Palm Beach - would be mapped into a Special Flood Hazard Area (SFHA) as a result. […] Before completing the Flood Insurance Study updates for the counties around Lake Okeechobee, FEMA Project Manager Mark Vieira proactively reached out to both the USACE and the South Florida Water Management District (SFWMD) to obtain their latest modeling. At that time it was discovered that the USACE was updating their two dimensional model for the Herbert Hoover Dike. FEMA put all five countywide studies on hold so that the new modeling results could be used in a comprehensive statistical analysis to determine the 1% annual chance flood event. […] The initial benefit of coordination with the USACE and SFWMD was multiple government agencies using the same model and information. But the real impact of this effort was through public outreach - how would FEMA help the counties and communities around Lake Okeechobee explain the SFHA changes to their citizens?"
