Mitigation strategies or activities fall into six general categories.
Prevention Preventative activities are intended to keep hazard problems from getting worse. They are particularly effective in reducing a community’s future vulnerability, especially in areas where development has not occurred or capital improvements have not been substantial. Examples of preventative activities include: •Open space preservation •Storm water management •Drainage system maintenance •Shoreline / riverine setbacks •Capital Improvement Plans/critical facility placement •Special assessment districts Local land use plans and ordinances can be used to limit development in hazard-prone areas or to from getting worse. Examples of local enforcement tools that can be used include: •Planning and zoning •Floodplain regulations
Property Protection Property protection measures protect new or existing structures by modifying the building to withstand hazardous events, or removing structures from hazardous locations. Examples include: •Acquisition •Relocation •Building elevation •Critical facilities protection •Building codes (enforcement) •Safe rooms •Basement backflow prevention •Retrofitting (i.e., windproofing, floodproofing, seismic design standards, etc.) •Wind shutters
Natural Resource Protection Natural resource protection activities reduce the impact of natural hazards by preserving or restoring natural areas and their mitigation functions. Such areas include floodplains, wetlands, and dunes. Parks, recreation, or conservation agencies, and organizations often implement these measures. Examples include: •Floodplain protection •Riparian buffers •Vegetative planting and treatment / slope stabilization / fire-resistant landscaping •Fuel breaks •Wetland preservation and restoration
