Through mitigation, the South Dakota Office of Emergency Management develops plans, programs and services to reduce or eliminate loss if the same disaster occurs again.
While we can not control the occurrence of events like tornadoes, floods or other disasters, we can directly influence the severity of impact by initiating pre-disaster mitigation planning, principles, and practices. The South Dakota Office of Emergency Management also offers mitigation grants to help communities eliminate or lessen the impact of a recurring event upon life and property.
2019 CHANGES TO MITIGATION PROGRAM
Mitigation actions are most often thought of as taking the form of structural or non-structural measures, but there are four basic approaches:
- Altering the Hazard: Modifying the hazard to eliminate or reduce the frequency of its occurrence. Examples include triggering avalanches under controlled conditions and reducing a storm’s energy through cloud seeding.
- Averting the Hazard: Redirecting the impact away from a vulnerable location by using structural devices or land treatment to shield people and development from harm. Examples include dikes, levees and dams.
- Adapting to the Hazard: Modifying structures and altering design standards of construction. Identified problem areas such as high wind, earthquake, land sliding or subsidence, and heavily forested terrain all require special building standards and construction practices in order to reduce vulnerability to damage.
- Avoiding the Hazard: Keep people away from the hazard area or limiting development and population in a risk area. Examples include enforcement actions such as zoning regulations, building codes and ordinances.
