What is Hazard Mitigation?
The term "Hazard Mitigation" describes actions that can help reduce or eliminate long-term risks caused by hazards, or disaster, such as floods, hurricanes, wildfires, landslides, tornadoes, earthquakes, dam failures, or terrorism. Hazard mitigation focuses on long-term strategies that help governments and citizens find ways to reduce hazard risks and disaster-related costs to communities. Efforts made to reduce hazard risks should be compatible with other community goals; mitigation is most effective when it is a part of the larger responsibility of the government, individuals, private businesses, institutions, and non-profits. As communities plan for new development and improvements to existing infrastructure, mitigation can and should be an important component of the planning effort.
While mitigation activities can and should be taken before a disaster occurs, after a disaster, hazard mitigation is essential. Oftentimes after disasters, repairs and reconstruction are completed in such a way as to simply restore damaged property to pre-disaster conditions. These efforts may “get things back to normal,” but the replication of pre-disaster conditions may result in a repetitive cycle of damage, reconstruction, and repeated damage. Hazard mitigation breaks this repetitive cycle by producing less vulnerable conditions through post-disaster repairs and reconstruction. The implementation of such hazard mitigation actions leads to building stronger, safer and smarter communities that are better able to reduce future injuries and future damage.
Hazard Mitigation Breaks the Cycle
When the same kind of disaster occurs in the same place, like flooding along the coast, it can cause repeated damage and require repeated reconstruction. This constant reconstruction becomes more expensive over time. Hazard mitigation breaks this expensive cycle of recurrent damage and increasing reconstruction costs by taking a long-term view of rebuilding and recovering following disasters - hazard mitigation builds a safer community from the beginning.
What Are the Benefits of Hazard Mitigation?
Reduces the loss of life, property, essential services, critical facilities and economic hardship.
Reduces short-term and long-term recovery and reconstruction costs.
Increases cooperation and communication within the community through the planning process.
Increases potential for state and federal funding for recovery and reconstruction projects.
What Types of Mitigation Techniques Can Be Utilized?
Hazard mitigation actions are commonly broken into six different categories:
Prevention – Keep hazard risk from getting worse
Property Protection – Modify existing development subject to hazard risk
Public Education & Awareness – Inform people about hazardous areas and mitigation actions
Natural Resource Protection – Reduce effects of hazards & improve quality of environment
Emergency Services – Actions taken to ensure continuity of emergency services
Structural Projects – Large manmade structures to control hazards
Common mitigation actions that are taken include the following:
Enforcement of building codes, floodplain management codes, and environmental regulations
Integrate hazard mitigation planning into local plans
Installing utility grid resilience, such as deploying smart grid technologies, raising flood barriers around key assets, expanding tree-trimming programs, and improving transmission line materials
Using nature-based solutions to mitigate against natural hazards, such as vegetated swales, green streets, waterfront parks, greenways, stormwater parks, and green roofs
Add or increase freeboard requirement (feet above base flood elevation) in your flood damage ordinance
Mitigating High-Hazard Potential Dams
Acquisition of relocation of structures, such as purchasing buildings located in a floodplain
Acquisition of hazard prone lands in their undeveloped state to ensure they remain at no risk of flooding
Retrofitting of structures & design of new construction such as elevating a home or building
Protecting critical facilities and infrastructure from future hazard events
Development and distribution of outreach materials related to hazard mitigation
Deployment of warning systems
Public safety measures such as continual maintenance of roadways, culverts and dams
