LMS Working Group Review:
Sections 5-7 5: Vulnerability Assessment
The extent of injury and damage that may result from a hazard event of a
given intensity in a given area. The vulnerability assessment should
address impacts of hazard events on the existing and future built
environment.
6: Mitigation Strategy
The mitigation strategy serves as the long‐term blueprint for reducing
the potential losses identified in the risk assessment
7: Plan Maintenance
Methodologies
MEMPHIS (Mapping for Emergency Management, Parallel Hazard
Information System) is hazard risk assessment software created by
Kinetic Analysis Corporation under contract with the Florida
Department of Community Affairs.
Hazus Mulit-Hazard (Hazus-MH) is FEMA’s risk assessment program
for hurricanes, flood, and earthquakes.
Shelters According to the 2010 2014 Statewide Emergency Shelter
ReportPlan, Citrus County has 3 shelter locations that meet the ARC standards. Two of theseThe 3 sites include a total of 7 8 separate buildings for a total capacity of 4,7503,647 persons. The buildings on the school campuses estimated deficit of shelter space in the county is 84,476168,703 square feet needed to house an additional 3,6298,820 persons. The report also addresses our Special Needs Shelter space requirements. It reflects the existence of 138 128 qualifying spaces, equaling 8,2807,680 square feet of capacity. This reflects a deficit surplus of 18,7204,320 square feet/312 72 persons of shelter space. Other buildings identified in the 2014 Statewide Emergency Shelter Plan that either do not meet the ARC standards, or were not yet surveyed, have a total risk capacity of 18,453 people.
Tornadoes Since tornadoes are unpredictable in their pattern, frequency, and
severity, all of Citrus County is vulnerable to tornado induced
damages.
Mobile homes and older construction will be most vulnerable.

Hurricane HAZUS 100 Year Probabilistic Event
Hazus estimates that about 1,761 buildings will be at least moderately
damaged. This is over 2% of the total number of buildings in the
region. There are an estimated 43 buildings that will be completely
destroyed.
Expected Building Damage by Occupancy : 100 - year Event
Hurricane HAZUS 100 Year Probabilistic Event
The model estimates that a total of 365,832 tons of debris will be
generated. Of the total amount, 289,545 tons
(79%) is Other Tree Debris. Of the remaining 76,287 tons,
Brick/Wood comprises 28% of the total, Reinforced
Concrete/Steel comprises of 0% of the total, with the remainder
being Eligible Tree Debris.
Expected Building Damage by Building Type : 100 - year Event
Hurricane The model estimates 4 households to be displaced due to the
hurricane. Of these, 1 people (out of a total population of 118,085)
will seek temporary shelter in public shelters.
The total economic loss estimated for the hurricane is 142.7 million
dollars, which represents 1.83 % of the total replacement value of the
region’s buildings. Building-Related Economic Loss Estimates (Thousands of dollars)
Hurricane HAZUS Historical Hurricane Event: Jeanne
The model estimates that a total of 29,663 tons of debris will be
generated.

Hurricane HAZUS Historical Hurricane Event: Jeanne
The total property damage losses were 5 million dollars. 1% of the
estimated losses were related to the business interruption of the
region. By far, the largest loss was sustained by the residential
occupancies which made up over 96% of the total loss.

Wildfire
Wildfire Fire Intensity Scale (FIS) identifies areas where significant fuel
hazards and associated dangerous fire behavior potential exist
The Wildland Urban Interface (WUI) Risk Index layer is a rating of
the potential impact of a wildfire on people and their homes.
For the Citrus project area, it is estimated that 137,948 people or 98
percent of the total project area population (141,215) live within the
WUI.

The Wildland Urban Interface (WUI) Risk Index layer is a rating of
the potential impact of a wildfire on people and their homes. The
key input, WUI, reflects housing density (houses per acre)
consistent with Federal Register National standards.

Land Subsidence
Land subsidence and sinkholes would impact the entire County in
the same manner; however, the risk is based primarily on past
occurrences and location/ relationship to known sinkhole hazard
areas. The majority of the sinkholes in Citrus County have occurred
in the northwestern part of the County, and many have impacted
roadways.

Hazardous Materials The analysis revealed that 32 93 properties (20 41 of which are
