Iberville Parish Office of Emergency Preparedness: Laurie Doiron – Iberville Parish OEP Director Dallas Shearer – Iberville Parish Council Mapping Coordinator Faye Gilliam – Iberville Parish 911 Supervisor Project Steering Committee: Major Johnny Blanchard - Iberville Parish Sheriff’s Office R.L. Downs - Safety Director, River West Medical Center David Dupont - Iberville Parish Building Inspector Dan McGrew - EHS, Atofina Brandon Mellion - Plaquemine Building Inspector Mayor John Overton, Sr. - Town of Maringouin Chief Chris Rivet - Bayou Sorrel Fire Department Chief Floyd Sanchez - St. Gabriel Fire Department George Zeringue - Iberville Parish Engineer Plan Summary The Iberville Parish Hazard Mitigation Plan establishes a comprehensive framework of community goals and objectives for mitigating the human, property, and monetary losses associated with natural and human-caused hazards. The Mitigation Plan identifies the hazards posing the greatest threat to Iberville Parish, overviews appropriate mitigation measures, and provides a detailed Action Plan for four principal loss-mitigation goals: 1) Reducing flood losses; 2) Increasing disaster resistance of Parish and municipal infrastructure; 3) Ensuring that new construction is hazard resistant; and 4) Identifying and implementing cost- effective hazard mitigation measures in a manner that raises community awareness of these measures. The Mitigation Plan also contains a Capabilities Assessment that provides a survey of the existing Federal, State of Louisiana, and Parish granting and funding programs available to help finance the plan’s mitigation goals. In addition, guidance for annual monitoring and progress reporting is also provided, along - i - Iberville Parish Hazard Mitigation Plan with provisions for revising and updating the larger Mitigation Plan itself through the outlined Three Year Review and Plan Amendment Process. Appendices to the Mitigation Plan include a Hazards Profile that describes a broad range of hazards that could potentially affect Iberville Parish. For natural hazards, appropriate definitions, scales, seasonality, and histories of occurrence within Iberville Parish are provided. For human-caused hazards, both technological and terrorist, definitions of specific threats are presented and, when appropriate, histories of such incidents within Iberville Parish are discussed. The profiles were written in 2004, and therefore do not have references to Hurricanes Katrina and Rita. The required five-year plan review and update will include updated profiles that address these storms and the effect on the Parish. A second appendix consists of a Risk Assessment Table, a table that examines essential facilities, critical infrastructure, and populations at risk with respect to their vulnerabilities to various hazard types, the size of potentially effected areas, and estimated replacement costs. A final appendix provides a record the input received from officials and the public at large at the series of town meetings that was held during the formulation of the Mitigation Plan. - ii -
