Sacramento County Appendix C.1 Local Hazard Mitigation Plan Update September 2011
C.1 Categories of Mitigation Measures Considered
The following categories are based on the Community Rating System.
Prevention
Emergency Services
Property Protection
Natural Resource Protection
Structural Projects
Public Information
C.2 Alternative Mitigation Measures per Category
Prevention
Preventive measures are designed to keep the problem from occurring or getting worse. Their
objective is to ensure that future development is not exposed to damage and does not increase
damage to other properties.
Planning
Zoning
Open space preservation
Land development regulations
Subdivision regulations
Floodplain development regulations
Stormwater management
Fuels management, fire breaks
Building codes
Firewise construction
(also see Property Protection)
Emergency Services
Emergency services protect people during and after a disaster. A good emergency services
program addresses all hazards. Measures include:
Warning (floods, tornadoes, ice storms, hail storms, dam failures)
NOAA weather radio all hazards
Sirens
Reverse 911
Sacramento County Appendix C.2 Local Hazard Mitigation Plan Update September 2011
Evacuation and sheltering
Communications
Emergency planning
Activating the emergency operations room (emergency management)
Closing streets or bridges (police or public works)
Shutting off power to threatened areas (utility company)
Holding children at school/releasing children from school (school district)
Passing out sand and sandbags (public works)
Ordering an evacuation (mayor)
Opening evacuation shelters (red cross)
Monitoring water levels (engineering)
Security and other protection measures (police)
Monitoring of conditions (dams)
Critical facilities protection (buildings or locations vital to the response and recovery effort,
such as police/fire stations, hospitals, sewage treatment plants/lift stations, power
substations)
Buildings or locations that, if damaged, would create secondary disasters, such as
hazardous materials facilities and nursing homes
Lifeline utilities protection
Health and safety maintenance
Property Protection
Property protection measures are used to modify buildings subject to damage rather than to keep
the hazard away. A community may find these to be inexpensive measures because often they
are implemented by or cost-shared with property owners. Many of the measures do not affect the
appearance or use of a building, which makes them particularly appropriate for historical sites
Establish better communication between dam owners and local communities
