City of Waveland, Mississippi Local Hazard Mitigation Plan

The City of Waveland, Mississippi developed this Local Hazard Mitigation Plan (LHMP) 2013 update to document Waveland’s hazard mitigation planning process, and to identify relevant vulnerabilities and strategies the City will use to increase resiliency and sustainability. Waveland was "ground zero" of Hurricane Katrina's landfall on August 29, 2005. The city received massive damage and is still in the process of recovering and rebuilding. 

This plan was prepared pursuant to the requirements of the Disaster Mitigation Act of 2000 so that Waveland would be eligible for the Federal Emergency Management Agency’s (FEMA) Pre-Disaster Mitigation and Hazard Mitigation Grant programs. The 2007 City of Waveland Hazard Mitigation and Flood Protection Plan and this 2013 update contain a risk assessment of identified hazards for the City. Nine new hazards were added to this current plan that were not addressed in 2007: climate change (storm surge, sea level rise); coastal/canal bank erosion; dam/levee failure; drought; earthquake; extreme heat; extreme winter weather; flood: stormwater/ localized flooding; and wildfire. 

The approach to organizing and preparing this plan is detailed in the report, including overall phases of the process, and the planning steps taken for each phase. The Risk Assessment is presented as four components: Hazard Identification, Hazard Profiles, Vulnerability Assessment, and a Capability Assessment. The impacts of climate change and sea level rise, both current and projected, are described in the Hazard Profiles section at length - along with extensive review of the other significant hazards affecting the region. 

The Vulnerability Assessment provides more information on predicted climate impacts and likelihood of occurrence. The potential impacts of climate change discussed include sea level rise, increased flooding frequency, and potential damage to critical infrastructure. Other significant impacts consider increasing public costs associated with flood insurance claims, infrastructure repair and maintenance, environmental impacts, as well as increased costs associated with emergency management efforts. 

The Capability Assessment lists regulatory mitigation capabilities, including planning and land management tools - and indicates those that are in place in the City of Waveland. Excerpts from applicable policies, regulations, and plans and program descriptions also provide more detail on existing mitigation practices.

As part of the plan update process, a comprehensive review and update of the mitigation strategy portion of the plan was conducted. 

The following umbrella mitigation strategy for this LHMP update was developed:

  • Communicate the hazard information collected and analyzed through this planning process as well as HMPC success stories so that the community better understands what can happen where and what they themselves can do to be better prepared.
  • Implement the action plan recommendations of this plan.
  • Use existing rules, regulations, policies, and procedures already in existence.
  • Monitor multi-objective management opportunities so that funding opportunities may be shared and packaged and broader constituent support may be garnered.

 Development of this plan was supported by a grant from FEMA.
