PREFACE
Natural Hazards are inevitable. Floods, tornadoes, winter storms, earthquakes, wildfires and other hazardous
events are normal occurrences in the natural environment. Disasters, however, occur when human activity (e.g.,
farming) and the built environment (e.g., structures) intersect with a natural hazard. Although natural hazards
themselves cannot be managed, many disasters can be avoided or mitigated. That is to say, the course or
magnitude of an earthquake cannot be managed but the characteristics of the built environment that will be
subject to that earthquake can be managed. An important task of local officials, and the purpose of a hazard
mitigation plan, is to identify and to eliminate the impact of natural hazards on human activity and the built
environment within their communities.
Hazard mitigation is defined as sustained action taken to significantly reduce or permanently eliminate longterm risk to human life and property from hazards and their effects. This definition distinguishes actions that
have a long-term impact from those that are more closely associated with preparedness for, immediate response
to, and short-term recovery from a specific event. This intent is to focus on actions that produce repetitive
benefits over time, not on those actions that might be considered emergency planning or emergency services.
The primary purpose of hazard mitigation is to ensure that fewer Americans and their communities are victims
of natural disasters. After disasters, repairs and reconstruction are often completed in such a way as to simply
restore damaged property to pre-disaster conditions. Such efforts expedite a return to normalcy. However,
replications of pre-disaster conditions result in a cycle of damage, reconstruction, and repeated damage. Hazard
mitigation is needed to ensure that such cycles are broken, that post-disaster repairs and reconstruction take
place after damages are analyzed, and that sounder, less vulnerable conditions are produced. An important
benefit of hazard mitigation is that current dollars spent on mitigation will significantly reduce the demand for
large amounts of future dollars when natural disasters strike, as well as reduce the economic disaster which
often accompanies the natural hazard event through destruction of property, loss or interruption of jobs, and
closing or disabling of businesses.
The rationale for mitigation is simple: it makes sense. It has been proven over and over again that the impacts
of natural hazards can be lessened and even eliminated by appropriate action taken well before the hazardous
event. The most effective way to ensure that this action takes place is the preparation and
implementation of a comprehensive hazard mitigation plan.
Hazard Mitigation Planning is the process that analyzes a community’s risk from natural hazards, coordinates
available resources, and implements actions to eliminate risk. A local mitigation plan should be prepared before
a disaster to guide risk reduction activities before an event; it should also be reviewed, and amended if
necessary, regularly to prevent the loss of significant mitigation opportunities.
Hazard mitigation planning is a collaborative process whereby hazards affecting the community are identified,
vulnerability to the hazards is assessed, and consensus reached on how to minimize or eliminate the effects of
these hazards. Through Section 409 of the Code of Federal Regulations (44 CFR 409), each state willing to
participate in the Hazard Mitigation Grant Program was required to have a State Hazard Mitigation Plan,
commonly referred to as the 409 Plan. The State of Tennessee foresaw the need for local
governments/communities to development their own mitigation plans. This foresight placed in effect the
requirement for all applicants wishing to receive hazard mitigation funding have in place a Local Hazard
Mitigation Plan that has been reviewed and approved by the Tennessee Emergency Management Agency.
When the Federal Emergency Management Agency (FEMA) reviewed the disaster experiences of the '90's they
became aware of the need to reassess their approach to disaster response and recovery. Based on this study,
6/22/2011

FEMA became aware of the nations need to shift its approach from a disaster-response driven system to a
system based on pre-disaster or ongoing risk analysis so that we could become proactive rather than reactive to
hazard events.
This acknowledgement caused FEMA to reevaluate their national strategy, resources and priorities. As a result
of this evaluation, a unit for Hazard Mitigation Planning was established within FEMA’s Directorate in 1998 to
provide guidance and resources to States and local communities to promote and support the mitigation planning
process. In support of their efforts, the requirement for mitigation planning became law through the Disaster
Mitigation Act of 2000 (DMA 2000) for both state and local governments. The 409 Plan (State Hazard
Mitigation Plan) is now referred to as the 322 Plan. Local entities desiring to apply for project funding under
the available mitigation grant programs must now have a local hazard mitigation plan approved by FEMA prior
to being eligible. The regulations containing the required information to be compiled in a local hazard
mitigation plan can be found in 44 Code of Federal Regulations 201.6.
FEMA’s goal is for State and local governments to develop comprehensive and integrated plans that are
coordinated through appropriate State, local, and regional agencies, as well as non-governmental interest
groups. To the extent feasible and practicable, FEMA would also like to consolidate the planning requirements
for different FEMA mitigation programs. This will ensure that one local plan will meet the minimum
requirements for all of the different FEMA mitigation programs, such as: Flood Mitigation Assistance Program,
Community Rating System, Pre-Disaster Mitigation Program, and the Hazard Mitigation Grant Program. The
mitigation plans may also serve to integrate documents and plans produced under other emergency management
programs.
Communities involved in the planning effort can make use of a newly developed natural hazard loss estimation
methodology developed by FEMA, in partnership with the National Institute of Building Sciences, called
Hazards US – Multi-hazards, or HAZUS - MH. Using Geographic Information Systems (GIS) technology,
HAZUS – MH allows users to compute estimates of damage and losses that could result from an earthquake,
wind (hurricanes, thunderstorms, tornadoes, extra tropical cyclones and hail) and flood (riverine and coastal)
hazards.
Another avenue of interest towards plan development is the partnership FEMA and National Oceanic and
Atmospheric Administration (NOAA). This partnership formed through the Multi-hazard Mapping Initiative,
to create multi-hazard mapping web pages. The objective of HazardMaps.gov is to maintain a living atlas of
hazards data and map services for advisory purposes supplied from a network of hazard and base map
providers.
The bottom line is hazard mitigation actions save lives and property!

INTRODUCTION
A. Purpose of Plan.
The purpose of this plan is to fulfill local Hazard Mitigation Plan requirements and also to substantially increase
public awareness of natural hazard risk so that the public demands safer communities in which to live and work;
and to significantly reduce the risk of loss of life, injuries, economic costs, and destruction of natural and
cultural resources that result from natural hazards. The plan will identify hazards; establish community goals
and objectives and select mitigation activities that are appropriate for Sumner County and the participating
municipalities.
The Disaster Mitigation Act of 2000 (DMA 2000), Section 322 (a-d) requires that local governments, as a
condition of receiving federal disaster mitigation funds, have a mitigation plan that describes the process for
identifying hazards, risks and vulnerabilities, identify and prioritize mitigation actions, encourage the
development of local mitigation and provide technical support for those efforts.
In addition, this plan will fulfill the requirements of the National Flood Insurance Reform Act of 1994
(NFIRA). With this act, Congress authorized the establishment of a Federal grant program to provide financial
assistance to States and communities for flood mitigation planning and projects. The Federal Emergency
Management Agency (FEMA) has designated this program as Flood Mitigation Assistance (FMA). FMA’s
basic goal is to fund cost-effective measures that reduce or eliminate the number of repetitively damaged
structures and associated claims against the National Flood Insurance Fund.
This plan will produce a program of activities that will improve Sumner County’s and the participating
municipalities’ hazard and flood problems and meet other community needs. Consistent with FEMA’s planning
process guidelines; the plan will accomplish the following objectives:

Ensure that all possible activities are reviewed and implemented so that disaster related hazards are
addressed by the most appropriate and efficient solution;

Link hazard management policies to specific activities;

Educate residents about potential hazards that threaten the community, including but not limited to winter
storms, tornadoes, floods and flashing flooding;

Build public and political support for projects that prevent new problems from known hazards and reduce
future losses;

Fulfill planning requirements for future hazard mitigation project grants; and,

Facilitate implementation of hazard mitigation management activities through an action plan.
B. Methodology
The methodology used for the development and updating of the Sumner County Multi-jurisdictional Hazard
Mitigation Plan, consisted of the following tasks:
1. Public involvement
6/22/2011
11
2. Coordination with other agencies and organizations
3. Hazard area inventory
4. Problem identification
5. Review and analysis of possible mitigation activities
6. Local adoption following a public hearing
7. Periodic review and update
This hazard mitigation plan contains a list of potential projects and a brief rationale or explanation of how each
project or group of projects contributes to the overall mitigation strategy outlined in the plan.
This plan summarizes the activities outlined above to assess the effects of floods/flash flooding,
tornadoes/windstorms and winter/ice storms hazards, etc. in Sumner County and the participating municipalities
and recommends mitigation activities.
The Hazard Mitigation Plan will be evaluated and updated every five years. In addition, the plan will be
updated as appropriate when a disaster occurs that significantly affects Sumner County or one of its
municipalities, whether or not it receives a Presidential Declaration. The update will be completed as soon as
possible, but no later than the 12 months following the date the disaster occurs.
Routine maintenance of the plan will include adding projects, as new funding sources become available or
taking projects off the list when they are accomplished.

PLANNING PROCESS
The Director of the Emergency Management Agency for the County began the planning process. A meeting
was held with the Sumner County Interagency Hazard Mitigation Plan Team and requested guidance from
TEMA and began work using the FEMA Mitigation Planning Workshop for Preparing and Reviewing Local
Plans G-318, specifically the Blue Book.
On October 2, 2009 letters were sent to all Mayors, the Sumner County Board of Education and Volunteer State
Community College giving them the choice of either participating in and eventually adopting the county’s plan
or writing their own and including it as an annex to the county plan before being submitted for approval. Also,
they were asked to appoint a representative from their municipality to serve on the Sumner County Interagency
Hazard Mitigation Plan Team.
The following municipalities chose to participate in the planning and adopt the County Hazard Mitigation Plan.

Each Team member officially represented their municipality and was responsible for input and data collection
and solicited input from the appropriate individuals and businesses within their municipality. Each Team
member attended the meetings, provided insight and feedback on actions taken by the Team.
The Sumner County Interagency Hazard Mitigation Plan Team met and members present begin evaluating the
plan from 2005. The team members determined if the listed hazards still applied, if any new hazards existed and
what, if any, changes need to be implemented. The team members agreed that all hazards did still exist and no
new hazards needed to be added. The team also looked at the previous plans objectives and goals to determine
what actions had been taken towards those goals, and if no actions taken, why no action had been taken
The County Commissioners formally sanctioned this planning process by accepting the conditions of a Hazard
Mitigation Grant from FEMA, which mandated the creation of a Hazard Mitigation Plan for Sumner County.
Public Input
An article, entitled Officials Brace for Extreme Weather, written by staff writer Sherry Mitchell was published
in the March 17, 2010 edition of The News Examiner. This article discussed weather and it’s history related to
Sumner County. The article also ask readers for input on the possible hazards by participating in an online
survey. The article goes on to explain Hazard Mitigation and it’s importance.(See article in Appendix 2)
Another article, entitled EMA has survey on natural disaster plans, was published in the March 18, 2010,
edition of The Gallatin Paper. This article explains the survey utilized to gather information related to the
public’s level of preparedness and it’ use in the planning process of the Sumner County Multi-Jurisdictional
Hazard Mitigation Plan. (See article in Appendix 2.)
Through advertising in the newspaper on the afore mentioned dates, the opportunity was granted to neighboring
communities, agencies, businesses, academia, nonprofits, and other interested parties to be involved in the
planning process. Public review of the draft plan was made available on the posted website before it was
presented formally for adoption. All comments received from the public were reviewed and incorporated into
the final version of the plan, as appropriate, with the final version presented via the website to the general public
for review and comment.
In the process of developing this plan the County participated in a regional planning process to integrate our
mitigation efforts with other jurisdictions and agencies. Other agencies involved in various stages of the
planning were: Federal Emergency Management Agency, Tennessee Emergency Management Agency,
National Weather Service, U.S. Geological Survey. These agencies have provided a wealth of assistance and
information.

III. RISK ASSESSMENT
Risk assessment is the process of measuring the potential loss of life, personal injury, economic injury, and
property damage resulting from natural or man-made hazards. The results of this risk assessment assisted
Sumner County and its incorporated and participating municipalities in identifying and understanding their risks
from natural and man-made hazards. This information also serves as the foundation for the development of the
mitigation plan and strategies to help reduce risks from future hazard events.
This risk assessment followed the methodology described in the FEMA publication 386-2 “Understanding Your
Risks – Identifying Hazards and Estimating Losses” and was based on a four-step process: 1) Identify Hazards,
2) Profile Hazard Events 3) Inventory Assets, and 4) Estimate Losses. Using FEMA guidance, as well as the
Section 322 regulations for developing local hazard mitigation plans a risk assessment that identifies the
following was developed.




The hazards to which the county and its communities are susceptible
The impact of these hazards on physical, social, and economic assets
The areas within the county most vulnerable to these hazards
The potential costs of damages or costs avoided through future mitigation projects
As part of the Sumner County mitigation plan update, unless otherwise stated in this document, Sumner County
and the participating municipalities or jurisdictions will be affected equally as it pertains to their risk
assessments.
A. Hazard Identification
The first step in the risk assessment process was to identify each of the hazards that could occur within Sumner
County and its incorporated and participating municipalities. This hazard identification process began with
researching previous hazard events based on historical data compiled by the National Climate Data Center of
NOAA from 1955 to 2010. Additional data collected came from newspaper reports, personal experiences,
public records, records kept in the Emergency Management Agency office and searching the Internet.
The following eleven natural hazards could occur within Sumner County and its municipalities: dam failure,
drought, earthquake, extreme heat, flood, hailstorm, land subsidence, winter/ice storm, tornado/windstorm,
wildfire and thunderstorm. From our research we found that the county and each of the participating
municipalities to be primarily susceptible to the following three hazards unless otherwise specified in this
section.
1. Floods/Flash Floods
Flooding is defined as a general and temporary condition of partial or complete inundation of normally dry land
areas from excess water from snowmelt, rainfall, or storm surge accumulates and overflows onto the banks and
adjacent floodplains.
Floods can be slow or fast rising but generally develop over a period of days. Several factors determine the
severity of floods, including rainfall intensity (or other water source) and duration. A large amount of rainfall
over a short time span can result in flash flood conditions.
6/22/2011
16
There are several different types of floods: flash, riverine, urban, and coastal. Obviously, coastal flooding
would not be a problem in Tennessee. There are several incidents of each of the other types annually, however.
Regardless of the type of flood, the cause can almost always be attributed to excessive rainfall, either in the
flood area or upstream. Since most precipitation in the state occurs between December and late March, this is
the period during which the majority of the flooding can be expected to occur. There are several instances each
year, however, of locally heavy rainfall throughout the year that results in flash flooding.
On an annual basis, flooding causes the most damage in Tennessee. From 1963 through 2009, flooding had
resulted in 32 presidentially declared disasters across the state, with expenditures nearing $100 million.
Flooding occurs 2 – 3 times a year in Sumner County, most of which is of the minor flash flood variety. Floods
typically affect 20 – 30% of the county’s population at any given time.
Flooding/Flash Flooding is arguably the highest priority natural hazard in Sumner County and each of the
participating municipalities. This is largely due to the physical geography of the county, which includes a river
and several creeks as well as a varied topography.
While Sumner County and all its jurisdictions are likely to only receive between a few inches and a foot of
flooding based on historical events, it is possible for all jurisdictions to receive more than 2 feet of flooding or
flash flooding during heavy rains.
The Cumberland River and Old Hickory Lake divides Sumner County on the south from Wilson and Davidson
Counties. Other large creeks run through various areas of Sumner County; among the many are Station Camp
Creek, Town Creek, Bledsoe Creek and Drakes Creek. There are also several city lakes with small dams used
for the communities’ water supplies.
Identification of floodplain areas within the county and participating municipalities was based on the most
recent Flood Insurance Rate Maps (FIRM) produced by FEMA dated November 21, 2002. The maps located in
Appendix 3 of this plan and titled “Flood Zone Maps” display the locations of all of the major water bodies in
the county and delineate the 100-year floodplain boundaries (Zone A). These are areas that have a one percent
chance of equaling or exceeding the recorded base flood elevation during any year. Based on these maps seven
out of the nine jurisdictions have 100-year floodplains within their jurisdictions, with the exceptions being
Mitchellville and Westmoreland. The Sumner County Flood Zone map also shows several areas in the
unincorporated portions of the county where 100-year floodplains have been identified.
The National Climate Data Center list 33 flooding events for Sumner County since 1994, but there have been
many smaller events not documented by the NCDC. Details of these events were ascertained through
interviews with emergency management and/or citizenry. The following page gives a breakdown of flood
events occurring in Sumner County from January 1995 to August 2010 based on Sumner County Emergency
Management and NCDC data.

The following chart gives a breakdown of Sumner County’s flood impacts within the last 5 years based on
NCDC and Sumner County Emergency Management data.
General flooding occurs almost annually in Sumner County and participating municipalities, and it is the most
common disaster in the county. Since 1994 flooding has resulted in approximately $445,000.00 in property
damage along.
There are several instances each year of locally heavy rainfall that results in flash flooding. Flash floods are
erratic and seldom hit the same area in consecutive years. They are sometimes more disastrous to life and
property than slow rise floods, since they may occur with little warning. Although flash floods have occurred
all across the county, they are most prevalent around creeks and ditches. The more prone areas to flash flooding
include Station Camp Creek between Long Hollow Pike and Hwy 31E in Gallatin and Drakes Creek between
Long Hollow Pike and Highway 386. These areas have resulted in flash flooding but no repeated or major
property loss. We also incorporated the maps from the United States Army Corps of Engineers mapping of the
flooding caused by the potential failure of Wolf Creek Dam. This map is utilized in the event of Old Hickory
Reservoir/Cumberland River flooding. Sumner County and the cities of Gallatin, Goodlettsville and
Hendersonville are also significantly affected by the potential failure of U.S. Army Corps of Engineers Wolf
Creek and Center Hill Dams. Sumner County and the affected jurisdictions have developed response plans for
the event of any dam failure and these plans have been incorporated into our emergency plans.
6/22/2011

The areas known for flooding will be mapped and we will use the 100-year floodplain overlay to determine the
vulnerabilities (Objective 4.3) just as soon as the digital information becomes available sometime the fall of
2005.
2. Tornadoes/Windstorms
A tornado is a violently whirling column of air extending downward to the ground with winds as high as 300
miles per hour. They may move forward at speeds up to 70 mph but generally average between 25-40 mph as
they move across land or water. Damage paths can be in excess of l mile wide and 50 miles long. However in
Tennessee, the average length is from a few hundred yards to three miles. Because of prevailing wind patterns,
59 percent of all tornadoes in the United States move from SW to NE and 97 percent from some westerly
direction. In a typical year in Tennessee, 11 tornadoes occur, killing five and injuring about a dozen of the
state's citizens. Since tornado statistics began in 1916 more than 525 tornadoes have impacted the state – 126 of
which have killed almost 450 people. Tornadoes occur more frequently in the western portion of the state than
in the middle or eastern portions.
The springtime months, from mid-March through the first of June, are the peak months for tornado activity;
however, tornadoes can and have occurred in every month of the year. The afternoon and early evening hours
from 3:00 P.M. to 9:00 P.M. are the best time for tornado development. In Sumner County and participating
municipalities significant tornadoes occur once every 3 – 4 years and may affect up to 30% of the county’s
population. Sumner County and participating municipalities has had a tornado occurrence in every month of the
year except July, August, September, October and December.
Predicting exactly what parts of Sumner County or its municipalities have a greater chance of being struck by a
tornado is difficult. The best predictor of future tornadoes is the occurrence of previous tornadoes. According
to records found via the Internet, there have been at least 31 recorded tornado events in Sumner County since
March 4, 1955. These tornadoes were characterized as EF0, EF1, EF2, EF3 and EF4 on the Enhanced Fujita
Tornado Measurement Scale, which categorizes tornadoes based on wind speed and expected damages. The
6/22/2011
20
next table shows the tornado category, expected damages, and corresponding wind speed for both the Fujita
Scale and the Enhanced Fujita Scale.
Sumner County and participating municipalities has had 37-recorded tornadoes since March 4, 1955 with 31
deaths, approximately 300 injured and $40 million plus in property damage. The following table below
describes all tornadoes that have occurred within Sumner County between January 1950 and August 2010
according to NCDC data. This is accompanied by a map of tornado movements for this timeframe in Sumner
County. The second table describes the impacts seen from tornadoes hitting Sumner County in the last five
years. The impacts from the 2006 tornado in Gallatin and the 2008 tornado in Castalian Springs has changed
the way Sumner County will look at tornadoes for generations.

For planning purposes it is less important to map the tornado risk than it is to identify it. This is because it is so
difficult to predict the path of future tornadoes, because they have occurred in just about every part of Sumner
County (including its municipalities) in the past. The Fujita scale provides us with an idea of the strength and
extent of damages of tornadoes that can occur throughout Sumner County (including its municipalities).
Additional resources to help understand the extent of tornado risks for our area are the “Design Wind Speed
Map” developed by the American Society of Civil Engineers (ASCE) and the “Tornado Activity in the United
States” map based on NOAA Prediction Center statistics. According to the WIND ZONES IN THE UNITED
STATES map, most of the state of Tennessee is located in Zone IV, which is an area associated with up to 250
mph wind speeds.
While Sumner County and all its jurisdictions are most likely to receive a tornado rated between a F0 and F2, it
is possible for all jurisdictions to receive a F4 or higher, like when Sumner County received a F4 in 1970.
6/22/2011
23
Using the TORNADO ACTIVITY IN THE UNITED STATES map, which shows 6-10 recorded tornadoes per
1,000 sq. miles, and the wind speed of 250 mph we find on the following diagram that Sumner County and the
participating municipalities are in an area of high risk. (Information obtained from FEMA’s Taking Shelter
From the Storm: Building a Safe Room Inside Your Home)
6/22/2011
24
Because tornadoes tend to strike at random it is virtually impossible to predict exactly what parts of Sumner
County or its municipalities have a greater chance of being struck by a tornado, therefore we must consider all
155,000 residents occupying the 66,000+ households as being vulnerable to tornadoes.
Extreme winds can cause several kinds of damage to a building. This figure shows how extreme winds affect a
building and helps explain why these winds cause buildings to fail. To understand what happens when extreme
winds strike, you must first understand that tornado and hurricane winds are not constant. Wind speeds, even in
these extreme wind events, rapidly increase and
decrease. An obstruction, such as a house, in the
path of the wind causes the wind to change
direction.
This change in wind direction
increases pressure on parts of the house. The
combination of increased pressures and
fluctuating wind speeds creates stress on the
house that frequently causes connections
between building components to fail. For
example, the roof or siding can be pulled off or
the windows can be pushed in.
Buildings that fail under the effects of extreme winds often appear to have exploded, giving rise to the
misconception that the damage is caused by unequal wind pressures inside and outside the building. This
misconception has led to the myth that during an extreme wind event, the windows and doors in a building
should be opened to equalize the pressure. In fact, opening a window or door allows wind to enter a building
and increases the risk of building failure.
Flying debris (referred to as windborne missiles) can also cause damage. If wind speeds are high enough,
missiles can be thrown at a building with enough force to penetrate windows, walls, or the roof. For example,
an object such as a 2” x 4” wood stud weighing 15 pounds, when carried by a 250-mph wind, can have a
horizontal speed of 100 mph and enough force to penetrate most common building materials used in houses
today. Even a reinforced masonry wall will be penetrated unless it has been designed and constructed to resist
debris impact during extreme winds. Because missiles can severely damage and even penetrate walls and roofs,
they threaten not only buildings but the occupants as well.

3. Winter/Ice Storms
The term Winter Storms includes ice storms, blizzards and extreme cold. Winter storms in Tennessee mostly
include extreme cold and ice. These storms are especially hazardous in terms of closing emergency routes,
creating power and utility system failures, and immobilizing economic activity. Because of the state's generally
mild winters, major storms occur on average about once every five years. When they do occur, they typically
affect as much as one half of the state's population. The potential, however, exists that a major storm could
affect the entire state. In March of 1993 the "Storm of the Century" struck the eastern half of the state killing 18
people and causing $22 million in damage. In 1994, a major ice storm created massive utility outages and road
damage over two-thirds of the state. The net result was over $100 million in damages--by far the largest
disaster in the state's history. Additionally, major snowstorms affected citizens of Tennessee in 1996 and 1998,
requiring both State and Federal Government response. The total combined cost of these winter storms was in
the $25 million range. On the average, winter storms occur once every 2 – 3 years, affecting the entire county
and the participating municipalities.
When it comes to actual winter/ice storms occurring within Sumner County and its jurisdictions, the county has
experienced impacts such as downed power lines, downed tree branches, closed roads, and automobile
accidents caused by “black ice.” One ice storm event, in March 2006, even led a small jet to slide off the
runway at the Portland Municipal Airport.
Sumner County and all its jurisdictions are most likely to receive one to three inches of snow based on historical
events, but could receive as much as 12 inches of snow, as occurred on March 19, 2006 in northern Sumner
County.
The following chart provides winter/ice storm events in Sumner County from January 1995 to August 2010
based on NCDC data.

B. Identifying Assets
The Multi-jurisdictional Hazard Mitigation Plan for Sumner County identifies critical facilities located in the
County and the hazards to which these facilities are susceptible. A critical facility is defined as a facility in
either the public or private sector that provides essential products and services to the general public, is otherwise
necessary to preserve the welfare and quality of life in the County, or fulfills important public safety,
emergency response, and/or disaster recovery functions.
The critical facilities identified in the County and the participating municipalities are shelters; hospital and other
health care facilities; gas, electric, and communication utilities; water and wastewater treatment plants; facilities
with flammable or toxic materials; schools; fire and police stations and government services. (See Appendix 5
for listing.)
The Hazard Mitigation Plan Team will use GIS and other modeling tools to map the county’s critical facilities
and determine which are most likely to be affected by hazards. The three hazards most likely to impact the
County and participating municipalities on a greater scale in order of priority are flooding/flash flooding,
tornadoes/windstorms, and winter/ice storms. The analysis revealed the following:

Flooding/Flash flooding Hazard: A 100-year flood could have an impact on a number of critical facilities
located in the 100-year flood hazard zone.

Tornado/Windstorm Hazard: All critical facilities could be affected.

Winter/Ice Storm Hazard: All critical facilities could be affected.
6/22/2011
27
In addition to critical facilities, the County and the participating municipalities contains at risk populations that
should be factored into a vulnerability assessment. These include a relatively large population of elderly
residents with limited mobility.
An analysis of the projected population figures for all of Sumner County indicates that the population will
continue to grow in the next 20 years. Most of the residential development is expected to occur in the already
developed areas outside of the 100-year floodplain.
C. Estimating Potential Losses
We will attempt to complete this portion once our GIS operators have completed the FEMA HAZUS/MH
Course and once the 100-year flood plain digitized information has been made available for our area .
D. Analysis of Land Uses and Development Trends
Sumner County is in the northern middle part of Tennessee. It has a total area of 543.12 square miles
(347,595.36 acres). The county is bounded on the north by the Tennessee-Kentucky State Line, on the east by
Macon and Trousdale Counties, on the south by the Cumberland River that separates Sumner from Wilson
County, and on the west by Robertson and Davidson Counties. Gallatin, the county seat, is approximately 30
miles northeast of Nashville. The Regional Map included within this plan illustrates the location of Sumner
County to surrounding counties and its relationship to the Nashville Metropolitan Area. (See Appendix 6 –
Sumner County and the Nashville Metropolitan Area)
The following land uses activities for Sumner County are listed below. The county zoning map included within
this plan illustrates the location and intensity of the land uses described below. (See Appendix 6 – Sumner
County Zoning)

Land with Physical Constraints
The term “constrained land” is intended to include a variety of conditions that significantly limit the use of
land for purposes other than woodland, pastures or other natural open land activities. Included in this group
are land areas subject to flood and wetlands. Areas that lay along the Cumberland River and its tributaries
along the southern borders of the county are examples of constrained lands.

Public
The Bledsoe Creek State Park located along Bledsoe Creek occupies 164 acres of land in the southeast part
of the county. This reserve provides a natural habitat for birds and animals and preserves bottomland
hardwood forests.
6/22/2011
28
Several lake and recreational areas are located along the Cumberland River in Sumner County. The U.S.
Army Corp of Engineers controls most, although a few areas are controlled by the Tennessee Wildlife
Resources Agency. They provide fishing, boating, picnic and hiking facilities for county area residents.

Commercial
Sumner County is somewhat typical in that much of the County’s major commercial use is located inside
the larger municipalities, primarily Gallatin and Hendersonville along with White House, Goodlettsville and
Portland. Scattered small commercial sites are located within the county at arterial and collector roads or
within cross roads communities, which serve the residents’ convenience needs.

Industry
Within Sumner County, major industry is located inside the larger communities and is likely to remain in
this condition due to infrastructure and services.

Agricultural
Agriculture has long been a significant element within the economy of Sumner County. Today much of
Sumner County remains farmland although some decrease in acreage can be attributed to urbanization
adjacent to the county’s municipalities. It is apparent that continued success of agriculture would require
protection of these lands for agricultural use, which in turn is one of the most difficult and complex land use
issues that face the county.

Residential
Within Sumner County the residential development trend has primarily occurred along the frontages of
major transportation routes, arterial and collector roads and the fringes of the incorporated communities.
The great majority of this growth consists of residential development on a minimum of one-area lots where
no public sewer exists and pocket areas of small subdivisions of one-half acre lots where approved sewer
exist. In the past few years, the pace of this activity has significantly risen with the outward migration of
residents of Davidson County. Many of the purchases of residential lots are focused on the local market for
employment; however an increasing proportion commutes to work in the Nashville area. The area wide
economy has mostly benefited from the associated growth; however, many of the municipalities have
become bedroom communities placing strains on the infrastructure and available community services.
Annexation has been one response to the rapid growth in Sumner County. As most of the municipalities in
the county are at or very near build-out there are not many undeveloped lots available for new
development. This coupled with the desire for subdivisions has increased the amount of development on the
fringes of the municipalities and in the unincorporated county. The response by some municipalities in the
county to this issue has been to annex the fringe developments and expand their municipal boundaries. This
increases the city tax bases but also increases the burdens on the municipalities to provide services and
infrastructure. Current trends indicate new challenges and will continue to be before the local government.
The County has grown by leaps and bounds in the last 10 to 15 years. This formerly rural, agricultural
County is rapidly becoming a populated residential region. A study, compiled by the County Tax
Assessor’s Office, starting with January 1, 2000 and going through December 31, 2004 showed 10,195 new
homes constructed, 586 modular homes and 643 mobile homes added in Sumner County during that 5-year
time frame. The population at this time is estimated to be well over 145,000.

The term “Land Use Areas” is intended to encompass a broad array of land uses and activities at a high or
moderate density including commercial, industrial and residential uses over the next twenty years. The
population projections, as shown above, indicate a possible need for expansions into undeveloped land areas
to accommodate growth. Based on history, economic trends, population growth and development trends,
there are specific areas within Sumner County that correspond to the “Land Use Area” definition. These
“Land Use Areas” are described as follows as taken from the Sumner County Land Use Plan.

The area 2,000 ft. north and south of Long Hollow Pike from Goodlettsville to Gallatin, and

The area along Lower Station Camp Creek and Big Station Camp Creek Boulevard south of Long Hollow
Pike to Nashville Pike.
Sumner County has a clear obligation to develop and maintain a growth management policy. To achieve this
purpose, the county’s current planning and zoning authority can implement growth management relative to the
uses and intensities of development within these designated areas. Moreover, the intensity of development
permitted will be directly linked to the availability of public infrastructure. These controls will preserve and
protect agricultural areas while at the same time support orderly urban expansion.
The Sumner County Zoning Map (see Appendix 6) included as part of this plan illustrates the Land Use Areas
as designated by the County. Each municipality is responsible for their own Land Use Areas. The County
“Land Use Area” represents approximately 10 percent of the total county land area while approximately 55
percent of the county is proposed to remain as “Rural Area.”
IV.
MITIGATION STRATEGY
A. Capability Assessment
The capability assessment identifies and evaluates existing systems including laws, standards, programs and
policies that either reduces or increase a jurisdiction’s vulnerability to hazards. This capability assessment
focused on the evaluation of Sumner County’s existing programs and policies to determine what vehicles
6/22/2011
30
are already in place to support mitigation activities. These policies and programs were identified based on a
review of existing plans and ordinances for the county and each of the municipalities.

National Flood Insurance Program (NFIP): The County of Sumner and all municipalities within the
county are participants or in the process of becoming participants in the National Flood Insurance
Program which provides flood insurance to homes and businesses located in floodplains at a reasonable
cost, and encourages the location of new development away from the floodplain. The program is based
upon mapping areas of flood risk, and requiring local implementation to reduce that risk, primarily
through guidance of new development in floodplains.
Congress created the NFIP in 1968 to minimize response and recovery costs and to reduce the loss of
life and damage to property caused by flooding. The Federal Emergency Management agency (FEMA)
administers the NFIP. The two fundamental objectives of NFIP are to:
1. Ensure that new buildings will be free from flood damage; and
2. Prevent new developments from increasing flood damage to existing properties.
The primary benefits of the NFIP are to:
1.
2.
3.
4.
Provide flood insurance coverage not generally available in the private market.
Stimulate local floodplain management to guide future development;
Emphasize less costly nonstructural flood control regulatory measures over structural measures; and
Reduce cost to the federal and state governments by shifting the burden from the general taxpayer to
floodplain occupants.
Community participation in the NFIP is voluntary. However, those communities that do not participate
are restricted by Federal sanctions for funding and support of floodplain development. The most
significant of these sanctions is the unavailability of disaster relief funds for personal property repair and
replacement under the Individual and Family Grant, Temporary Housing and Small Business
Administration low interest loan programs.

Repetitive Loss Properties: According to the National Flood Insurance Program, repetitive flood loss is
defined as a facility or structure that has experienced two or more insurance claims of at least $1,000 in
any given 10 year period since 1978. Until the May 2010 flood events that swept through west and
middle Tennessee, Sumner County only had one property that could be considered a repetitive loss.
From the May 2010 flood event alone, Sumner County now has 24 single family residential properties
that are considered as repetitive losses. Out of those over 70% of the properties were located in the City
of Hendersonville. The chart below provides a summary of repetitive losses for the county as of August
2010.


Emergency Management Agency: The County of Sumner created the Sumner County Emergency
Management Agency (formerly the Gallatin-Sumner County Civil Defense established in 1953) in 1996
as a result of changing Federal and State requirements. Sumner County Emergency Management
Agency (SCEMA) is committed to the purpose of developing plans and procedures that would provide
the most effective and efficient coordination of resources available in the mitigation of, planning and
preparedness for, response to and recovery from emergencies and disasters.
Sumner County has been and will continue to be subject to a wide variety of hazards that have the
potential for causing significant damage and/or loss of life. It is imperative that local government
agencies, as well as the citizens at large be prepared to deal effectively with the results brought about by
the occurrence of such events.
The agency is also responsible for helping prepare the citizens of Sumner County to deal with
emergencies and their consequences.

Sumner County Emergency Management Plan: This plan establishes the framework for the
development of a comprehensive emergency management program within and for Sumner County and
its various political subdivisions. The emergency management program's purpose is to mitigate the
potential effects of the various hazards that might impact the county, to prepare for the implementation
of measures which will preserve life and minimize damage, to respond effectively to the needs of the
citizens and local jurisdictions during emergencies, and to provide a recovery system to return the
county and its communities to a normal status as soon as possible after such emergencies. This plan
defines the roles and responsibilities associated with the mitigation, preparedness, response, and
recovery efforts directed at natural disasters, technological accidents, enemy attacks, and other major
events that might impact Sumner County.

Warning System: At this point in time SCEMA advocates the broad usage of the NOAA Weather
Radio (NWR) by everyone. NWR is a nationwide network of radio stations broadcasting continuous
6/22/2011
32
weather information directed from a nearby National Weather Service (NWS) office. NWR broadcasts
NWS warnings, watches, forecasts and other hazard information 24 hours per day.

Geographic Information Systems (GIS): Sumner County began GIS in 2000, when the county
learned it would participate in the Tennessee Base Mapping Program. As a result of the project, Sumner
County has high-quality GIS data and is well ahead of most counties in Tennessee.
GIS is a computer-based mapping and geographic analysis program. The Sumner County GIS
Committee is responsible for coordinating GIS data sharing among government agencies and is the
custodian for base map layers for use by these agencies and the public.

American Red Cross: the Nashville Area Chapter of the American Red Cross, which provides
emergency preparedness and disaster awareness programs relating to floods, severe storms, tornadoes,
earthquakes and other disasters that might affect Sumner County, serves Sumner County. The ARC
supports appropriate legislation; however, it does not take the lead in these matters. (January 5, 1905
Congressional mandate; Public Law 93-288, Disaster Relief Act of 1974; statement of under-standing
between FEMA and ARC)

The National Weather Service: The National Weather Service (NWS) provides weather, hydrologic,
and climate forecasts and warnings for the protection of life and property and the enhancement of the
national economy. NWS data and products form a national information database and infrastructure,
which can be used by other governmental agencies, the private sector, the public, and the global
community.

NOAA Alert System: NOAA, the voice of the National Weather Service, provides up to date weather
information, 24 hours a day, every day of the year. Watches, Warnings, and weather statements from
the NWS are given out over the NOAA Alert System. It is also a major part of the Emergency Alert
System that speeds critical information through commercial broadcast outlets.

The Central United States Earthquake Consortium (CUSEC): CUSEC is an organization of 7 states
(Tennessee, Arkansas, Illinois, Indiana, Kentucky, Missouri and Mississippi) dedicated to earthquake
awareness, hazard reduction and research.
CUSEC’s goal is to ensure that planners, developers, building officials, lenders, insurance
representatives and other key players understand the potential consequences of earthquakes, and begin to
incorporate mitigation into the daily decisions that are made on sitting, design, and construction of
buildings and lifelines.
They are also available for presentations on the earthquake threat to Sumner County and earthquake
preparedness.

Department of Agriculture (USDA):
Forest Service – Their primary responsibility lies in prevention and suppression of wild land fires on all
land outside of municipalities. All activities are aimed at reducing the number of fires and the acres
burned through fire prevention, fire suppression, training, and working with rural fire department.
The TDF requires a burning permit be obtained before any open burning is done between October 15
and May 15.
6/22/2011
33
Soil Conservation Service – The SCS can provide technical assistance in the conservation, development
and productive use of soil and water resources. Their activities include:
(1) Watershed Protection and Flood Prevention
The SCS provides technical and financial assistance to local organizations to plan and install works
of improvement for watershed protection, flood prevention, agricultural water management, and
other approved purposes. (Watershed Protection and Flood Protection Act, Public Law 83-566)
(2) Floodplain Management Studies
Assistance for cooperative floodplain management studies is provided to local communities or units
of government to provide information and large-scale mapping needed in alleviating potential flood
dangers. Funding is 80/20. (Public Law 83-566, Section 6)
(3) Emergency Watershed Protection
Emergency watershed protection assistance is provided to reduce hazards to life and property in
watersheds damaged by severe natural events. (Section 403-405, Agricultural Credit Act of 1978;
Section 216, Flood Control Act of 1950, Public Law 81-576)
(4) Conservation Technical Assistance
In addition to the specific program activities, the SCS can provide technical assistance to land users
in the planning and application of conservation treatments to control erosion and reduce upstream
flooding along with other purposes such as sediment reduction. (Public Law 74-46)

Sumner County Planning Commission: The Sumner County Regional Planning Commission consists
of a 15-member board appointed by the Sumner County Legislative Body. One member serves as the
Chairman, four members also serve as County Commissioners for Sumner County, and the remaining
members are appointed citizens.
The Planning Commission oversees general development of subdivision plats, re-zoning requests, and
reviews and makes recommendations for amendments to the Sumner County Zoning Resolution and
Subdivision Regulations. The commission promotes orderly growth and development in Sumner County
by maintaining a comprehensive planning program, which minimizes land use conflicts, coordinates the
provision of public service, and optimizes the quality of life for all county residents.

Sumner County Zoning: A resolution to regulate in the portions of Sumner County which lie outside
of municipal corporations, the location, height, bulk, number of stories and size of buildings and other
structures, the percentage of the lot which may be occupied, the sizes of yards, courts and other open
spaces, the density of population, and the use of buildings, structures and land for trade, industry,
residence, recreation, agriculture, forestry, soil and water conservation, public activities and other
purposes including areas subject to flooding.
The first Zoning Resolution was adopted in July of 1973. It was amended in May of 2003.
The Sumner County Zoning Board of Appeals consists of five (5) members. It is an administrative
device, serving in a Quasi-Judicial role by which Sumner County can provide for special cases on a useby-use, lot by lot basis without amending the Zoning Resolution. They also provide the citizens of
6/22/2011
34
Sumner County a mechanism for review of interpretative decisions of the Zoning Resolutions' enforcing
officers; Planning Director, Building Commissioner and Building Inspector.
State and local law with three (3) distinct powers vest the Board of Appeals;
1. The power of Administrative Review.
2. The power to grant certain authorized Special Exceptions.

and hardening of roads and bridges as a result of repair or replacement. TDOT maintains an inventory
of barricades and high water signs for use in the event of roadway flooding; personnel monitor streams
as flood warnings dictate. TDOT maintains personnel and equipment to clear roadways in the event of
blockage from storms, tornadoes, winter storms, and landslides.

All municipalities have a Board of Mayor and Aldermen or Councilmen who can enact and enforce
zoning, zoning restrictions, and amendments and also budget monies for these purposes.

All municipalities are included in the Metropolitan Planning Organization, which researches,
documents and makes recommendations to the City Boards concerning the passage of regulations that
would effect hazard mitigation.

All municipalities have a Building and Code Enforcement representative to inspect and enforce
regulations.
B. Goals, Objectives and Strategies
This section provides information on the process used to develop goals and objectives that pertain to the
natural hazards addressed in the mitigation plan. It also describes the framework that focuses the plan on
developing successful mitigation strategies. The framework is made up three parts: the Mission, the Goals,
and the Objectives.
6/22/2011
35
The mission of the Sumner County Multi-jurisdictional Hazard Mitigation Plan is to promote sound public
policy designed to protect citizens, critical facilities, infrastructure, private property, and the environment
from natural hazards. This can be achieved by increasing public awareness, identifying activities to guide
the county and the municipalities towards building safer, more sustainable communities.
The plan goals describe the overall direction that Sumner County agencies, organizations, and citizens can
take to minimize the impacts of natural hazards. The goals are stepping-stones between the broad direction
of the mission statement and the specific objectives that are outlined in the action items.
Objectives are developed as a means of realizing the county’s hazard mitigation goals. Objectives are more
specific and tangible than goals. Rather than being long-term and general, objectives should be achievable
in a definite period of time. Under each objective are actions that are specific activities or services that will
be performed in order to accomplish or support the Objective.
1. Mitigation Plan Goals, Objectives and Actions
Public input during development of the mitigation plan assisted in creating the goals. Meetings with the
Interagency Hazard Mitigation Plan Team and stakeholder interviews served as methods to obtain input
and identify priorities in developing goals, objectives, and actions for reducing risk and preventing loss
from natural hazards in Sumner County. The goals listed were determined to be those that would have
the greatest benefit in hazard reduction to the County and the participating municipalities. The goals,
objectives, and actions are prioritized by the frequency and associated cost (through a cost benefit
review) with each hazard occurrence and are listed in the order in which they were prioritized. The
goals, objectives and actions are as follows:
Goal #1 – Protect public health, safety and welfare by increasing the governmental agencies and
public awareness of existing hazards and by fostering both individual and public
responsibility in mitigating risks due to those hazards in Sumner County and the
jurisdictions participating in the Hazard Mitigation Plan.
Objective 1.1 – Increase the public awareness of natural hazards that can and do affect Sumner
County, especially in the high hazard areas.
 Action 1.1.1 – Continue to publish articles in the local newspaper to increase public awareness of

C. Implementation of Mitigation Measures
1. Process
6/22/2011
43
The County Executive and the Mayor of each Municipality, and as specified within this plan will implement
the Sumner County Multi-jurisdictional Hazard Mitigation Plan through the delegation of assignments. In
this section our goals, objectives and actions are listed and assigned specific implementation measures
which include the assignment of responsibilities to County/City departments and/or specific County/City
staff, along with the establishment of a target completion date for each proposed mitigation action. When
applicable, potential funding sources are also listed.
Projects will be prioritized and selected for implementation based primarily on a positive cost/benefit ratio
and include the following five criteria as well, community goals, planning objectives, funding availability,
environmental concerns and public support. In determining which projects should be submitted for funding,
calculations will be based on a FEMA approved cost/benefit method as found in FEMA’s How to Determine
Cost-Effectiveness of Hazard Mitigation Projects publication.
2. Funding Sources
Although all mitigation techniques will likely save money by avoiding losses, many projects are costly to
implement. Sumner County will continue to seek outside funding assistance for mitigation projects in both
the pre- and post-disaster environment. This portion of the Plan identifies some grant programs for Sumner
County to consider, and also briefly discusses local and non-governmental funding sources.
Title:
Agency:
Pre-Disaster Mitigation Program
Federal Emergency Management Agency
Through the Disaster Mitigation Act of 2000, Congress approved the creation of a national program to
provide a funding mechanism that is not dependent on a Presidential disaster declaration. The Pre-Disaster
Mitigation (PMD) Program provides funding to states and communities for cost-effective hazard mitigation
activities that complement a comprehensive mitigation program, and reduce injuries, loss of life, and
damage and destruction of property.
The funding is based upon a 75 percent Federal share, 25 percent non-Federal share. The non-Federal
match can be fully in-kind or cash, or a combination. Special accommodations will be made for “small and
impoverished communities”, who will be eligible for 90 percent Federal share, 10 percent non-Federal.
FEMA provides PDM grants to states that, in turn, can provide sub-grants to local governments for
accomplishing the following eligible mitigation activities.







State and local hazard mitigation planning
Technical assistance [e.g. risk assessments, project development]
Mitigation Projects
Acquisition or relocation of vulnerable properties
Hazard retrofits
Minor structural hazard control or protection projects
Community outreach and education [up to 10% of State allocation]
Title:
Agency:
6/22/2011
Flood Mitigation Assistance Program
44
FEMA’s Flood Mitigation Assistance (FMA) program provides funding to assist states and communities in
implementing measures to reduce or eliminate the long-term risk of flood damage to buildings,
manufactured home, and other structures insurable under the National Flood Insurance Program (NFIP).
FMA was created as part of the National Flood Insurance Reform Act of 1994 (42 U.S.C. 4101) with the
goal of reducing or eliminating claims under the NFIP.
FMA is a pre-disaster grant program, and is made available to states on an annual basis. This funding is
available for mitigation planning and implementation of mitigation measures only, and is based upon 75
percent Federal share, 25 percent non-Federal share. States administer the FMA program and are
responsible for selecting projects for funding from the applications to FEMA for an eligibility
determination. Although individuals cannot apply directly for FMA funds, their local government may
submit an application on their behalf.
Title:
Agency:
Hazard Mitigation Grant Program
The Hazard Mitigation Grant Program (HMGP) was created in November 1988 through Section 404 of the
Robert T. Stafford Disaster Relief and Emergency Assistance Act. The HMPG assists states and local
communities in implementing long-term mitigation measures following a Presidential disaster declaration.
To meet these objectives, FEMA can fund up to 75 percent of the eligible costs of each project. The state or
local cost-share match does not need to be cash; in kind services or materials may also be used. With the
passage the Hazard Mitigation and Relocation Assistance Act of 1993, federal funding under HMGP is now
based on 15 percent of the federal funds spent on the Public and Individual Assistance programs (minus
administrative expenses) for each disaster.
The HMPG can be used to fund projects to protect either public or private property, so long as the projects
in question fit within the state and local government’s overall mitigation strategy for the disaster area, and
comply with program guidelines. Examples of projects that may be funded include the acquisition or
relocation of structures from hazard-prone areas, the retrofitting of existing structures to protect them from
future damages; and the development of state or local standards designed to protect buildings from future
damages.
Eligibility for funding under the HMGP is limited to state and local governments, certain private nonprofit
organizations or institutions that serve a public function, Indian tribes and authorized tribal organizations.
These organizations must apply for HMGP project funding on behalf of their citizens. In turn, applicants
must work through their state, since the state is responsible for setting priorities for funding and
administering the program.
Title:
Agency:
Public Assistance (Infrastructure) Program, Section 40
FEMA’s Public Assistance Program, through Section 406 of the Robert T. Stafford Disaster Relief and
Emergency Assistance act, provides funding to local governments following a Presidential disaster
declaration for mitigation measures in conjunction with the repair of damaged public facilities and
infrastructure. The mitigation measures must be related to eligible disaster-related damages and must
directly reduce the potential of future, similar disaster damages to the eligible facility. These opportunities
usually present themselves during the repair/replacement efforts.
6/22/2011
45
Proposed projects must be approved by FEMA prior to funding. They will be evaluated for cost
effectiveness, technical feasibility, and compliance with statutory, regulatory and executive order
requirements. In addition, the evaluation must ensure that the mitigation measures do not negatively impact
a facility’s operations or risk from another hazard.
Public facilities are operated by state and local governments, Indian tribes or authorized tribal organizations
and include:





Roads, bridges and culverts
Draining and irrigation channels
Schools, city halls and other buildings
Water, power and sanitary systems
Airports and parks
Private nonprofit organizations are groups that own or operate facilities that provide services otherwise
performed by a government agency and include, but are not limited to the following:






Universities and other schools
Hospitals and clinics
Volunteer fire and ambulance
Power cooperatives and other utilities
Custodial care and retirement facilities
Museums and community centers
Title:
Agency:
Unmet Needs Program
Unmet Needs is a Federal grant program provided by the Emergency Supplemental Appropriations Act.
Funded periodically by an allocation from Congress, Unmet Needs is provided through the Federal
Emergency Management Agency (FEMA), yet is managed at the State level. The program provides flexible
grants to help cities, counties, and States recover from specific Presidential disasters declared under Title IV
of the Robert T. Stafford Disaster Relief and Emergency Assistance Act, as amended. Unmet Needs funds
are intended to fund cost-effective measures under the categories of mitigation, buyout assistance, disaster
relief, and long-term recovery directly related to specific disasters where the needs are unable to be met
through other federal grants programs. The number and amount of needs remaining after a specific year’s
disasters determine Unmet Needs funding.
Title:
Agency:
Small Business Administration Disaster Assistance Program
U.S. Small Business Administration
This program provides loans to businesses affected by presidentially declared disasters. The program
provides direct loans to businesses to repair or replace uninsured disaster damages to property owned by the
business, including real estate, machinery and equipment, inventory and supplies. Businesses of any size
are eligible. Nonprofit organizations are also eligible. The Small Business Administration administers the
Disaster Assistance Program.
6/22/2011
46
The recipients of SBA loans can utilize that money to incorporate mitigation techniques into the repair and
restoration of their business.
Title:
Agency:
Community Development Block Grants
U.S. Department of Housing and Urban Development
The Community Development Block Grant (CDBG) program provides grants to local governments for
community and economic development projects that primarily benefit low- and moderate-income people.
The CDBG program also provides grants to entitlement communities (metropolitan cities and urban
counties) for post-disaster hazard mitigation and recovery following a Presidential disaster declaration.
Funds can be used for activities such as acquisition, rehabilitation or reconstruction of damaged properties
and facilities and redevelopment of disaster-affected areas. Funds may also be used for emergency response
activities, such as debris clearance and demolition and extraordinary increases in the level of necessary
public services. The U.S. Department of Housing and Urban Development (HUD) provides funds for the
CDBG program and the Division of Community Assistance administers the program in each state.
LOCAL GOVERNMENT
Local governments depend upon local property taxes as their primary source of revenue. These taxes are
typically used to finance services that must be available and delivered on a routine and regular basis to the
general public. If local budgets allow, these funds are used to match Federal or State grant programs when
required for large-scale projects.
NON-GOVERNMENTAL
Another potential source of revenue for implementing local mitigation projects are monetary contributions from
non-governmental organizations, such as private sector companies, churches, charities, community relief funds,
the Red Cross, hospitals and other non-profit organizations.

V. MAINTENANCE PROCESS
A. Monitor, Evaluate, and Update
The Interagency Hazard Mitigation Plan Team will meet annually to monitor, evaluate and/or amend the
plan. At this meeting the Committee will consider the following points.






Review and evaluate the goals and objectives
Determine if the nature or magnitude of risk has changed
Evaluate whether the current resources are adequate for implementing the plan
Review completed mitigation work
Look for available funding sources for future projects
Request and document public participation in the plan review
In addition, the plan will be updated as appropriate when a disaster occurs that significantly affects Sumner
County or one of its municipalities whether or not it receives a Presidential Declaration. A special meeting
should be held within a month following each disaster event to determine if any changes are needed in the
plan.
The plan should be updated within five years of the initial approval date granted by FEMA. In the event of
any substantial changes in land use planning or regulations that would impact the recommended mitigation
projects, more frequent updates should be considered. The Interagency Hazard Mitigation Plan Team in
partnership with the local planning departments and emergency management will be responsible for
overseeing the update of the hazard mitigation plan. The update process will be similar to the one used to
develop the original plan and will incorporate opportunities for public involvement.
B. Public Participation
The annual meeting will be advertised to encourage public attendance and input. Any actions taken at this
meeting will be submitted in writing to all interested parties, including, but not limited to, the County
Mayor, Municipality Mayors/Managers, the TEMA regional office and active members of the committee.
Subsequent evaluations and updating of the plan within the five-year cycle will involve public ads in the
local newspapers. Copies of the plan will be made available at the Sumner County Administration Building,
the various city halls, the Chambers of Commerce and on the website.
C. Incorporation
Sumner County currently utilizes comprehensive land use planning, capital improvements planning, and
building codes to guide and control development in the County and Municipalities. Responsible agencies
for the aforementioned planning, will review the data presented in the hazard mitigation plan and will
incorporate pertinent information in their respective documents. Likewise, data presented in those
publications will be reviewed for pertinence and incorporated into the hazard mitigation plan. After the
official adoption of the Hazard Mitigation Plan, these existing mechanisms will have hazard mitigation
strategies integrated into them.
Specifically, five of the goals in the Hazard Mitigation Plan direct the County and the participating
Municipalities to reduce loss of life and property from natural hazard events. The County Planning
6/22/2011
48
Department will conduct periodic reviews of the County’s comprehensive plans and land use policies,
analyze any plan amendments, and provide technical assistance to the municipalities in implementing these
requirements.
The Building and Codes Enforcement office for the County and for each municipality are responsible for
administering the building codes in their respective jurisdictions. After the County and each municipality
adopts the Hazard Mitigation Plan, they will work with the State Building Code Enforcement office to make
sure they have adopted, and are enforcing, the minimum standards established by the State. This is to
ensure that life/safety criteria are met for new construction within the County.
The capital improvement planning that occurs in the future will also contribute to the goals in the Hazard
Mitigation Plan. The Planning Commission will work with capital improvement planners to secure highhazard areas for low risk uses.
Within six months of the formal adoption of the Hazard Mitigation Plan, the policies listed above will be
incorporated into the process of existing planning mechanisms of the County and each of the participating
municipalities.
As of the 2010 Sumner County mitigation plan update, information from the mitigation plan has been
incorporated into other planning mechanisms. Risk assessment information from the County’s mitigation
plan has been included in the county’s Basic Emergency Operation Plan (BEOP) during it’s update three
years ago, the updated critical facilities list that is housed in the Sumner County mitigation plan was
included in the county’s Tier II document, and updated floodplain maps and information about areas highly
vulnerable to floods, as seen in the mitigation plan, has been included in the county’s codes.

EMA has survey on natural disaster plans
The Gallatin Newspaper
March 18, 2010
The Sumner County Emergency Management Agency wants to hear from citizens on updating its
plan to prepare for the threats that natural disasters like tornadoes and flood pose to Sumner County
residents and their properties.
EMA has a “Hazard Mitigation” link on the county’s website, www.sumnertn.org, which features a
Household Natural Hazards Preparedness Questionnaire.
The survey includes questions about what kinds of natural disasters the survey-taker has
experienced and how they have prepared for these somewhat unpredictable forces of nature.
“People can take the survey through April 25,” said Ken Weidner, director of Sumner County
Emergency Management Agency. “We’d like to get as many people as we can to take the survey
and submit it to us.”
The results of the surveys will be included in the updated multi-jurisdictional hazard mitigation plan
that municipalities in the county are working on together to submit to the Tennessee Emergency
Management Agency (TEMA).
With the updated plan in place, the county can qualify for funds to take an even more proactive
approach to being prepared for natural disasters.
In addition to the county’s efforts to plan and secure money, citizen can take some measures to
prepare for any natural disasters, Weidner said.
Storing portable water, canned goods or sand bags in the event of a 50-year flood are some ways of
becoming prepared.
Some common items citizens can stock up on include food, water, flashlights, batteries, a batterypowered radio, medical supplies like a first-aid kit, a fire extinguisher, a smoke detector on each level
of the house and a disaster supply kit.
Getting first aid and CPR training, making a fire escape plan, knowing where to go and who to call in
the event of a disaster and discussing utility shutoffs are other ways citizens can prepare themselves
for catastrophes.
When people think of natural disasters, tornadoes often come to mind but seismic activity is also a
concern with fault lines located in both east and west Tennessee, Weidner noted. Experts have
speculated for years that the effects of a major earthquake along fault lines could be felt in Middle
Tennessee Communities.
“There’s some potential for damage from an earthquake,” he said. “That’s one of the major priorities.”
Aside benefit of planning for natural disasters is that it will contribute to the county’s economic
development, public safety and welfare, government efficiency and environmental protection,
according to TEMA literature.
“We’re complying with regulations to receive funding and so that our citizens can receive assistance
for the Small Business Administration or FEMA,” he said.
An example of this is that municipalities can qualify for dollars they can use for debris removal after
storms, Weidner said. “They spend weeks getting things cleaned up,” he said. “Cities can ask for
reimbursement for that.”

Officials brace for extreme weather
Survey asks residents’ level of preparedness
By Sherry Mitchell
THE NEWS EXAMINER
March 17, 2010
While many are glad to see warmer weather on the way, spring brings about the threat of something
much more sinister – destructive tornadoes. It’s something that local residents know about all too
well.
For the next few months, first responders will be on guard during the peak of potential deadly storms.
“We’ve had tornadoes in February, July and November, but the months of March, April and May are
our biggest concerns,” said Ken Weidner, director of Sumner County Emergency Agency. “This is the
peak season.”
Weidner said he and his staff are preparing should a natural disaster strike Sumner Count y again,
and they want to be sure that citizens are prepared as well.
As part of the county’s hazard mitigation plan to prepare for such threats such as tornadoes and
floods, local residents are being asked in an online survey how well they are prepared.
The survey, mandated by the Tennessee Emergency Management Agency, asks residents what
types of natural disasters they have experienced and how they prepared for these situations.
Based on past events in Tennessee, officials say the need for natural disaster preparedness can’t be
underestimated.
“Since 1950, tornadoes have killed 304 people in Tennessee, with an additional 3,860 injuries,” said
Bobby Boyd, National Weather Service meteorologist. “Tornadoes have killed more people in the
state of Tennessee than floods, straight-line winds and lightning combined.”
Earthquake possible in Tennessee
While tornadoes and flooding are two major concerns for the Middle Tennessee area, residents also
should be aware of the threat of earthquakes. Weidner said fault lines are located in both east and
west Tennessee, and the fear of a major local earthquake could become a reality.
“We have some potential for an earthquake here,” Weidner said. “It’s one of our major priorities.
We’ve seen a lot of seismic activity. A few years ago, we had an earthquake in Illinois that was felt
here.”
The Hazard Mitigation Plan will help local economic development, public safety and government
