City of Portland, Tennessee
General Fund
Fund Balance Policy 2023
Policy
The following policy has been adopted by the City Council in order to address the implications
of the Governmental Accounting Standards Board (“GASB”) Statement No. 54 Fund Balance
Reporting and Governmental Fund Definitions. The purpose of this policy is to establish a key
element of the financial stability of the City by setting guidelines for fund balance. Unassigned
fund balance is an important measure of economic stability. It is essential that the City maintain
adequate levels of unassigned fund balance to mitigate financial risk that can occur from
unforeseen revenue fluctuations, unanticipated expenditures, and similar circumstances, and to
maintain favorable bond ratings. Also, the fund balance provides cash flow liquidity for the
City’s general operations. Factors for maintaining sufficient fund balance include the ability to:









Maintain covenants of third-party agreements.
Provide funds for enacted Ordinances and Resolutions of the Board of Mayor and
Alderman.
Mitigate State budget actions that may reduce City revenue.
Mitigate economic downturns that the City may face in the future.
Front-fund or complete fund, if necessary, disaster costs or costs associated with
emergencies.
Fund the City’s expenditures and debt service payments during the first few months of
the fiscal year before traditional revenues are realized.
For non-recurring expenses identified as necessary by the Board of Mayor and Aldermen.
Fund one-time capital expenses identified as necessary by the Board of Mayor and
Aldermen.

This policy and the procedure promulgated under it supersede all previous policies regarding the
City’s fund balance and reserve policies.
Fund Balance Classifications
Fund Balance – An accounting distinction is made between the portions of fund equity that are
spendable and non-spendable. These are broken up into five categories:
1) Non-Spendable Fund Balance – Amounts that are not in a spendable form or are
required to be maintained intact. Examples are inventory or permanent funds.
2) Restricted Fund Balance – Amounts that can be spent only for the specific purposes
stipulated by external resource providers either constitutionally or enabling legislations.
Examples include grants and child safety fees.
3) Committed Fund Balance – Amounts that can be used only for the specific purposes
determined by a formal action of the government’s highest level of decision-making

Page 2 of 5
Ordinance # 23‐26

authority. Commitments may be changed or lifted only by the City Legislative Body
taking the same formal action that imposed the constraint originally.
4) Assigned Fund Balance – Amounts that are intended to be used by the government for
specific purposes. Intent can be expressed by the governing body or by an official or
body to which the governing body delegates the authority. In governmental funds other
than general fund, assigned fund balance represents the amount that is not represents the
amount that is not restricted or committed. This indicates that resources in other
governmental funds are, at a minimum, intended to be used for the purpose of that fund.
Assigned funds cannot cause a deficit in unassigned fund balance.
5) Unassigned Fund Balance – Amount is the residual classification of the general fund
and includes all amounts not contained in other classifications. Unassigned amounts are
technically available for any purpose.
Order of Use of Restricted and Unrestricted Funds
When both restricted and unrestricted funds are available for expenditure, it shall be the policy of
the City to use the restricted amounts first as permitted under the law.
When committed, assigned, and unassigned funds are available for expenditure, committed funds
should be spent first, assigned funds second, and unassigned funds last.
Authority to Commit Funds
The City’s governing body has the authority to set aside funds for a specific purpose. Any funds
set aside as Committed Fund Balance requires the passage of an ordinance by a simple majority
vote. The passage of an ordinance must take place prior to June 30th of the applicable fiscal year.
If the actual amount of the commitment is not available by June 30th, the ordinance must state the
process or formula necessary to calculate the actual amount as soon as information is available.
Authority to Assign Funds
The City’s governing body has the authority to set aside funds for the intended use of a specific
purpose. Any funds set aside as Assigned Fund Balance requires the passage of a resolution by a
simple majority vote. The same action is required to change or remove the assignment. Upon
passage of a budget ordinance where assigned fund balance is used to balance the budget, the
Finance Director shall record the amount as “Assigned Fund Balance”.
Minimum Level of Unassigned Fund Balance
Unassigned Fund Balance is the residual Fund Balance in the General Fund. It represents the
resources available for future spending. An appropriate level of unassigned fund balance should
be maintained in the General Fund to cover unexpected expenditures and revenue shortfalls. The
unassigned fund account shall have five subaccounts.
The unassigned fund balance in the General Fund shall have the following subaccounts:

Page 3 of 5
Ordinance # 23‐26

A. Cash Flow Stabilization Subaccount
The Cash Flow Stabilization Subaccount is intended to provide reserves to mitigate the
deficiencies caused by the timing of the cash inflows and cash outflows.
The Cash Flow Stabilization Subaccount shall be set at a minimum of 20% of General
Fund operating budgeted expenditures less any capital outlay and project amounts.
B. Contingency Subaccount
The Contingency Subaccount is intended for unanticipated expenses and revenue
shortfalls impacting programs already approved in conjunction with the current year’s
budget. The Contingency Subaccount shall not be used to fund new programs or positions
added outside of the current year’s budget.
Funds in the Contingency Subaccount may be used towards expenses outside of the
budget only as follows:
1) A change in legislation creating an unfunded mandate.
2) Large, unexpected payroll/retirement payouts.
3) A technical correction in the budget.
4) Unbudgeted project expense overrun.
The Contingency Subaccount shall be set at a minimum of 3% of General Fund operating
budgeted expenditures.
C. Emergency Subaccount
The Emergency Subaccount is intended for unforeseen urgent events. To utilize funds
from the Emergency Subaccount, a finding by the Mayor, with confirmation by the Board
of Aldermen, of “urgent economic necessity” will be required, as well as a determination
that no other viable sources of funds are available. A finding of urgent economic
necessity would be based on a significant event, for example, a natural disaster or
catastrophe.
The Emergency Subaccount shall be set at a minimum of 5% of General Fund operating
budgeted expenditures.
D. Debt Service Subaccount
The Debt Service Subaccount is intended to provide reserve funds for shortfalls in
budgeted revenues intended for general obligation debt service payments or unexpected
and unbudgeted expenditures related to general obligation debt service as well as any
unbudgeted expense related to the service and maintenance of the City’s debt liabilities.
The Debt Service Subaccount shall have a shall be set at a minimum of 3% of General
Fund operating budgeted expenditures.
E. Future Project/Capital Outlay Subaccount
The Future Project/Capital Outlay Subaccount shall be the balance of Unassigned Fund
Balance after the Contingency, Emergency, Cash Flow Stabilization, and Debt Service
Page 4 of 5
Ordinance # 23‐26

Subaccounts are funded. This Subaccount shall be used to fund one-time capital
expenditures. If this subaccount is used to balance the budget, it shall state “Cash used for
Capital Expenditures”.
The Future Project/Capital Outlay Subaccount shall have a minimum balance of at least
$250,000.
Any budget amendment that will result in the unassigned fund subaccounts dropping below the
minimum level, it will require the approval of a majority of the Board of Mayor and Aldermen.
If any subaccount drops below the minimum level amount, the Board of Mayor and Aldermen
shall develop a plan to replenish the fund balance to establish the minimum amount level within
two years.
Fund Balance Policy Adoption
The City’s Fund Balance Policy shall be adopted by Resolution by the Board of Mayor and
Aldermen. The policy shall be reviewed by the approving authority and the same authority must
approve any modifications. It is recommended that the policy be reviewed every year within six
months following budget approval. This policy will be managed and monitored by the Finance
Department and report on the current and projected level of reserve funds in conjunction with the
budget process. If necessary, the Finance Director will present recommendations for any
amendments, deletions, additions, improvements, or clarifications.

Resolution # 23-50

City of Portland, TN
Debt Management Policy
May 15, 2023
Introduction:
The purpose of this debt management policy is to establish a set of parameters by which
debt obligations will be undertaken by the City of Portland, TN. This policy reinforces the
commitment of the City and its officials to manage the financial affairs of the City to
minimize risks, avoid conflicts of interest and ensure transparency while still meeting the
capital needs of the City. A debt management policy signals to the public and the rating
agencies that the City is using a disciplined and defined approach to financing capital
needs and fulfills the requirements of the State of Tennessee regarding the adoption of a
debt management policy.
The goal of this policy is to assist decision makers in planning, issuing, and managing debt
obligations by providing clear directions as to the steps, substance, and outcomes desired.
In addition, greater stability over the long term will be generated using consistent
guidelines in issuing debt.
Definition of Debt:
All obligations of the City to repay, with or without interest, in installments and/or at a
later date, some amount of money utilized for the purchase, construction, or operation of
City resources. This includes but is not limited to notes, bond issues, capital leases, and
loans of any type whether from an outside source such as a bank or from another internal
fund.
Approval of Debt:
Bond anticipation notes, capital outlay notes, grant anticipation notes, and tax and
revenue anticipation notes (including any interfund loans), and certain non‐exempt
financing leases will be submitted to the State of Tennessee Comptroller’s Division of Local
Government Finance and the City Council prior to adoption of the authorizing resolution
for capital outlay notes and prior to issuance or entering into all other notes. A plan for
refunding debt issues will also be submitted to the Comptroller’s Office prior to adoption
of the authorizing resolution by the governing body and issuance.
Transparency:



The City shall comply with legal requirements for notice and for public meetings
related to debt issuance.
All notices shall be posted in the customary and required posting locations,
including as required local newspapers, bulletin boards, and websites.
Page 2 of 8

Resolution # 23-50





All costs (including principal, interest, issuance, continuing, and one‐time) shall be
clearly presented and disclosed to the citizens, City Council, and other stakeholders
in a timely manner.
The terms and life of each debt issue shall be clearly presented and disclosed to
the citizens/members, City Council, and other stakeholders in a timely manner.
A debt service schedule outlining the rate of retirement for the principal amount
shall be clearly presented and disclosed to the citizens/members, City Council, and
other stakeholders in a timely manner.

Role of Debt:




Long‐term debt shall not be used to finance current operations. Long‐term debt
may be used for capital purchases or construction identified through capital
improvement, regional development, transportation, or master process or plan.
Short‐term debt may be used for certain projects and equipment financing as well
as for operational borrowing; however, the City will minimize the use of short‐term
cash flow borrowings by maintaining adequate working capital for enterprise
funds, available cash for governmental funds, and close budget management.
In accordance with Generally Accepted Accounting Principles and state law,
1. The maturity of the underlying debt will not be more than the useful life of
the assets purchased or built with the debt, not to exceed 30 years;
however, an exception may be made with respect to federally sponsored
loans, provided such an exception is consistent with law and accepted
practices.
2. Debt issued for operating expenses must be repaid within the same fiscal
year of issuance or incurrence.

Types and Limits of Debt:






The City will seek to limit total outstanding annual debt service obligations to 40%
of tax assessments and local option tax revenues, excluding overlapping debt,
enterprise debt, and revenue debt.
The limitation on total outstanding debt must be reviewed prior to the issuance of
any new debt.
The City’s total outstanding debt obligation will be monitored and reported to the
City Council annually by the finance director during the budget preparation
process. The finance director shall monitor the maturities and terms and
conditions of all obligations to ensure compliance. Also, the finance director shall
report to the City Council any matter that adversely affects the credit or financial
integrity of the City.
Historically, the City has issued and is authorized to issue General Obligation
bonds, Revenue bonds, TIFs, leases, notes, financing leases and other debt allowed
by law. The City has determined it currently will not issue complex debt
instruments such as swaps or derivatives.
Page 3 of 8

Resolution # 23-50








The City will seek to structure debt with level or declining debt service payments
over the life of each individual bond issue, loan, or other debt obligation.
The City may utilize non‐level debt methods. However, the use of such methods
must be thoroughly discussed in a public meeting and the Mayor and City Council
must determine such use is justified and in the best interest of the city, as well as
submitted to the Comptroller’s Office for approval.
The City may use financing leases (formerly called capital leases) to finance
projects. The City will follow the guidance established by the Comptroller of the
Treasury, Division of Local Government Finance when assessing potential financing
leases. This guidance is pursuant to TCA 9‐24‐101 “Uniformity in Local Government
Lease Financing Act of 2021” and the Division of Local Government Finance’s Debt
Manual.
Bonds backed with a general obligations pledge often have lower interest rates
than revenue bonds. The City may use its General Obligation pledge with revenue
bond issues when the populations served by the revenue bond projects overlap or
significantly are the same as the property tax base of the City. The City Council and
management are committed to maintaining rates and fee structures of revenue
supported debt at levels that will not require a subsidy from the City’s General
Fund.

Use of Variable Rate Debt:



The City recognizes the value of variable rate debt obligations and that cities have
greatly benefitted from the use of variable rate debt in the financing of needed
infrastructure and capital improvements.
However, the City also recognizes there are inherent risks associated with the use
of variable rate debt and will implement steps to mitigate these risks, including:
1. The City will annually include in its budget an interest rate assumption for
any outstanding variable rate debt that takes market fluctuations affecting
the rate of interest into consideration.
2. Prior to entering into any variable rate debt obligation that is backed by
insurance and secured by a liquidity provider, the City Council shall be
informed of the potential affect on rates as well as any additional costs that
might be incurred should the insurance fail.
3. Prior to entering into any variable rate debt obligation that is backed by a
letter of credit provider, the City Council shall be informed of the potential
affect on rates as well as any additional costs that might be incurred should
the letter of credit fail.
4. Prior to entering into any variable rate debt obligation, the City Council will
be informed of any terms, conditions, fees, or other costs associated with
the prepayment of variable rate debt obligations.
5. The City shall consult with persons familiar with the arbitrage rules to
determine applicability, legal responsibility, and potential consequences
associated with any variable rate debt obligation.
Page 4 of 8

Resolution # 23-50

6. The City will avoid over‐reliance on variable rate debt due to the volatility
seen in credit markets.
Use of Derivatives:



The City chooses not to use derivatives or other exotic financial structures in the
management of the City’s debt portfolio.
Prior to any reversal of this provision:
1. A written management report outlining the potential benefits and
consequences of utilizing these structures must be submitted to the City
Council; and
2. The City Council must adopt a specific amendment to this policy concerning
the use of derivatives or interest rate agreements that complies with the
State Funding Board Guidelines.

Bonds ‐ Methods of Sale:



Competitive ‐ In a competitive sale, the City's bonds shall be awarded to the bidder
providing the lowest true interest cost as long as the bid adheres to the
requirements set forth in the official notice of sale.
Negotiated ‐ While the City prefers the use of a competitive process, the City
recognizes some bonds are best sold through negotiation. In a negotiated sale, the
underwriter(s) will be chosen through a Request for Qualification (RFQ) process
and the interest rate and underwriter's fees are negotiated prior to the sale. The
factors to be considered for a negotiated sale include the following:
1. Volatility of market conditions
2. Size of bond sale and credit strength
3. Whether the bonds are issued as variable rate demand obligations

Costs of Debt:





All costs associated with the initial issuance or incurrence of debt, management,
and repayment of debt (including interest, principal, and fees or charges) shall be
disclosed prior to action by the City Council in accordance with the notice
requirements stated above.
In cases of variable interest or non‐specified costs, a detailed explanation of the
assumptions shall be provided along with the complete estimate of total costs
anticipated to be incurred as part of the debt issue.
Costs related to the repayment of debt, including liabilities for future years, shall
be provided in context of the annual budgets from which such payments will be
funded (General Obligations bonds in context of the General Fund, Revenue bonds
in context of the dedicated revenue stream and related expenditures, loans and
notes).

Refinancing Outstanding Debt:
Page 5 of 8
Resolution # 23-50





The City will refund debt when it is in the best financial interest of the City to do so,
and the Finance Director shall have the responsibility to analyze outstanding bond
issues for refunding opportunities. The Comptroller’s Office must review the
refunding plan prior to the decisions being approved by the governing body, and all
plans for current or advance refunding (no longer tax‐exempt) of debt must be in
compliance with state laws and regulations.
The finance director will consider the following issues when analyzing possible
refunding opportunities:
1. Onerous Restrictions – Debt may be refinanced to eliminate onerous or
restrictive covenants contained in existing debt documents, or to take
advantage of changing financial conditions or interest rates.
2. Restructuring for Economic Purposes – The City will refund debt when it is
in the best financial interest of the City to do so. Such refunding may
include restructuring to meet unanticipated revenue expectations, achieve
cost savings, mitigate irregular debt service payments, or to release reserve
funds. Current refunding opportunities may be considered by the finance
director if the refunding generates positive present value savings, and the
finance director must establish a minimum present value savings threshold
for any refinancing.
3. Term of Refunding Issues – The City will refund bonds within the term of
the originally issued debt. However, the finance director may consider
maturity extension, when necessary to achieve a desired outcome,
provided such extension is legally permissible. The finance director may
also consider shortening the term of the originally issued debt to realize
greater savings. The remaining useful life of the financed facility and the
concept of inter‐generational equity should guide this decision.
4. Escrow Structuring – The City shall utilize the least costly securities available
in structuring refunding escrows. Under no circumstances shall an
underwriter, agent or financial advisor sell escrow securities to the City
from its own account.
5. Arbitrage – The City shall consult with persons familiar with the arbitrage
rules to determine applicability, legal responsibility, and potential
consequences associated with any refunding.

Professional Services:
The City shall require all professionals engaged in the process of issuing debt to clearly
disclose all compensation and consideration received related to services provided in the
debt issuance process by both the City and the lender or conduit issuer, if any. This
includes “soft” costs or compensations in lieu of direct payments.


Counsel: The City shall enter into an engagement letter agreement with each
lawyer or law firm representing the City in a debt transaction. No engagement
letter is required for any lawyer who is an employee of the City or lawyer or law
firm which is under a general appointment or contract to serve as counsel to the
Page 6 of 8

Resolution # 23-50

City. The City does not need an engagement letter with counsel not representing
the City, such as underwriters’ counsel.

Sumner County
Hazard Mitigation Plan
2023 Update

Prepared BY:
Sumner County Hazard Mitigation Planning Committee
Sumner County Emergency Management Agency/Office of Emergency Management

Assistance Provided By:
Tennessee Emergency Management Agency
as part of the Tennessee Mitigation Initiative

Executive Summary
Over the past two decades, hazard mitigation has gained increased national attention due
to the large number of natural disasters that have occurred throughout the U.S. and the
rapid rise in costs associated with those disaster recoveries. It has become apparent that
money spent mitigating potential impacts of a disaster event can result in substantial
savings of life and property. With these benefit-cost ratios extremely advantageous, the
Disaster Mitigation Act of 2000 was developed as U.S. Federal legislation reinforcing the
importance of pre-disaster mitigation planning by calling for local governments to develop
mitigation plans (44 CFR 201).
A local hazard mitigation plan aims to identify the community’s notable risks and specific
vulnerabilities and then to create/implement corresponding mitigation projects to address
those areas of concern. This methodology helps reduce human, environmental, and
economic costs from natural and man-made hazards through the creation of long-term
mitigation initiatives.
The advantages of developing a local hazard mitigation plan are numerous and include
improved post-disaster decision-making, education on mitigation approaches, and an
organizational method for prioritizing mitigation projects. Communities with a mitigation
plan receive larger amounts of Federal and State funding opportunities to be used on
mitigation projects and can receive these funds faster than communities without a plan.
This 2023 update of the Sumner County Hazard Mitigation Plan addresses Building
Resilient Communities and Infrastructure (BRIC), Flood Mitigation Assistance (FMA), and
Hazard Mitigation Grant Program (HMGP) requirements. Each jurisdiction within the county
participated in the preparation of the update, including:
• Sumner County
• Town of Westmoreland
• City of Gallatin
• City of Whitehouse
• City of Goodlettsville
• Sumner County Board of
• City of Hendersonville
Education
• City of Millersville
• Volunteer State Community
• City of Mitchellville
College
• City of Portland
In reference to federal code title 44 CFR 201, the plan is required to be submitted to both
TEMA (State) and FEMA (Federal) for review to be approved. When the plan is deemed
“approval pending adoption” by FEMA (44 CFR 201.6(c)5), each of the participating
jurisdictions will adopt the plan through a local resolution.

CHAPTER 1: THE PLANNING PROCESS

Chapter 1. The Planning Process
1.1 Purpose and Need, Authority and Statement of Problem
1.1.1 Purpose and Need
FEMA defines “hazard mitigation” as any sustained action taken to reduce or eliminate the
long-term risk to life and property from a hazard event. Hazard mitigation planning is the
process through which hazards are identified, likely impacts determined, mitigation goals
set, and appropriate mitigation strategies defined, prioritized, and implemented. The
Hazard Mitigation Plan aims to identify, assess, and mitigate risk to better protect the
people and property of Sumner County from the effects of natural and man-made hazards.
This Plan documents the hazard mitigation planning process and identifies relevant
hazards, vulnerabilities, and strategies the County and incorporated jurisdictions will use to
decrease vulnerability and increase resiliency and sustainability. This Plan demonstrates
the participating communities’ commitment to reducing risks from identified hazards and
serves as a tool to help decision-makers direct mitigation activities and resources.

1.1.2 Authority
This Hazard Mitigation Plan has been adopted by Sumner County and all participating
jurisdictions in accordance with the authority granted to local communities by the State of
Tennessee. This Plan was updated per state and federal rules and regulations governing
local hazard mitigation plans. The Plan shall be reviewed annually and go through a
complete update process every five years to remain eligible for hazard mitigation grants. The
following legislation was used for guidance:
•

•

Section 322 of the Robert T. Stafford Disaster Relief and Emergency Assistance Act
(Stafford Act or the Act), 42 U.S.C. 5165, enacted under Section 104 of the Disaster
Mitigation Act of 2000 (DMA 2000) Public Law 106-390 of October 30, 2000, as
implemented at 44 CFR 201.6 and 201.7 dated October 2011.
Tennessee Code Annotated
• T.C.A. 58-2-106(b)(16)
• T.C.A. 58-2-106(b)(1)
• T.C.A. 58-2-103(a)(5)

1.1.3 Statement of Problem
Each year in the United States, natural disasters take the lives of hundreds of people and
injure thousands more. Taxpayers pay billions of dollars annually to help communities,
organizations, businesses, and individuals recover from disasters. Unfortunately, this only
partially reflects the cost of disasters because additional expenses incurred by insurance
companies and non-governmental organizations are not reimbursed by tax dollars. Many
natural disasters are predictable, and much of the damage caused by these events can be
reduced or even eliminated.

CHAPTER 1: THE PLANNING PROCESS

The original Sumner County Hazard Mitigation Plan was created and approved by FEMA in
2023. Per federal requirements stated in 44 CFR 201, all local hazard mitigation plans are
required to go through a FEMA approval process every five years to remain eligible for
hazard mitigation grants. This plan will be re-evaluated and updated every five years to
ensure local governments are continuing to assess the hazards and risks within their
communities. This plan update has been prepared to meet requirements set forth by FEMA
and the Tennessee Emergency Management Agency (TEMA) to ensure Sumner County is
eligible for funding and technical assistance from state and federal hazard mitigation
programs. All communities are welcome to address man-made hazards and risks in their
hazard mitigation plan. However, it's important to note that the State and Federal
governments only evaluate and approve based on natural hazards only as per federal code
title 44 CFR 201.

1.2 Methodology, Update Process, and Participation Summary
This Hazard Mitigation Plan was developed under the guidance of a Hazard Mitigation
Planning Committee (HMPC). The Committee included representatives of Sumner County,
Gallatin, Goodlettsville, Hendersonville, Millersville, Mitchellville, Portland, Westmoreland,
White House, Sumner County Board of Education, and Volunteer State Community College.
Information in this plan will help guide and coordinate mitigation activities and decisions
for local land use policy in the future. Proactive mitigation planning will help reduce the
cost of disaster response and recovery to communities and their residents by protecting
critical community facilities, reducing liability exposure, and minimizing overall community
impacts and disruptions. This plan identifies activities that can be undertaken by both the
public and the private sectors to reduce risk to safety, health, and property caused by
natural and man-made hazards.

1.2.1 Local Government Participation
The planning regulations and guidance stress that each local government seeking FEMA
approval of their mitigation plan must participate in the planning effort in the following
ways:
•
•
•
•

Participate in the process as part of the HMPC;
Detail where within the planning area the risk differs from that facing the entire area;
Identify potential mitigation actions; and
Formally adopt the plan.

For the HMPC, “participation” meant the following:
•
•
•
•
•

Providing facilities for meetings;
Attending and participating in the HMPC meetings;
Collecting and providing other requested data (as available);
Identifying mitigation actions for the plan;
Reviewing and providing comments on plan drafts;

CHAPTER 1: THE PLANNING PROCESS

•
•
•

Informing the public, local officials, and other interested parties about the planning
process and providing opportunity for them to comment on the plan;
Coordinating, and participating in the public input process; and
Coordinating the formal adoption of the plan by the appropriate governing body.

The HMPC met all the above-stated participation requirements. Sumner County and all its
incorporated jurisdictions (Gallatin, Goodlettsville, Hendersonville, Millersville, Mitchellville,
Portland, Westmoreland, White House, Sumner County Board of Education, Volunteer State
Community College.) participated in the 2023 Plan update, as well as reviewed and
provided timely comments on all draft components of the Plan. A summary of past and
current community participation is shown below in Table 1. All participants were invited to
this committee via email by the County EMA Director. Those who did not originally respond
were reached out to via phone or email by the County EMA Director.

The HMPC for the 2023 plan update included key community representatives. Table 2
details the HMPC members, meeting dates, associated FEMA Lifeline, and committee
member attendance. FEMA Lifelines are fundamental way for a community to recover,
however, all participants might not be associated with a FEMA Lifeline. If they are not
associated with a FEMA Lifeline, then they will be indicated as not applicable (NA).
The EMA director invited individuals who represented regional and local agencies that have
authority in regulating county/city development, individuals that represent vulnerable
populations, as well as those that are responsible for responding to the identified hazards
of prime concern. These partners include jurisdictional police, fire, public works, and health
departments, community representatives, nonprofit organizations, local floodplain
administration, the county/city school board, elected officials, and electric utility
companies. Induvial from all sectors were invited to attend the HMPC meetings, those that
chose to attend are listed. All committee members provided key information to recognize
and mitigate hazards of prime community concern. A more detailed summary of HMPC
meeting dates, members seeking approval and FEMA lifeline association follows in Table 2.

CHAPTER 1: THE PLANNING PROCESS

1.2.2 Hazard Mitigation Planning Process
The 2023 Sumner County Hazard Mitigation Plan was updated following guidance put forth
by FEMA in the Local Mitigation Planning Policy Guide which became effective on April 19,
2023. This guidance emphasized the need for a whole community planning approach to
include representatives from all sectors of the community with an emphasis on the
increased need for vulnerable and underserved population representation. The guidance
also highlighted increased emphasis on risk, vulnerability, and resilience assessments, the
inclusion of high hazard dams, and future weather trends/patterns.
FEMA guidance proposes a structured four-phase approach to completing a Hazard
Mitigation Plan as follows:
1)
2)
3)
4)

Planning Process
Risk Assessment
Mitigation Strategy
Plan Maintenance

Phase I - Planning Process
Organize to Prepare the Plan
The planning process officially began with a meeting held on March 30, 2023 at the Sumner
County EOC. The meeting covered the scope of hazard mitigation, the purpose of planning,
eligible grants, risk assessments and vulnerabilities impacting the community. During the
planning process, the committee communicated through face-to-face meetings, email, and
telephone conversations. The neighboring communities were given an opportunity to be
involved in the planning process with email invitations by the County EMA Director for the
planning committee meetings. The City of White House, which is part of both Sumner
County and Robertson County chose to attend.
Involve the Public
Early discussions established the significance of involving the public. The HMPC agreed to
an approach using established public information mechanisms and resources within the
community. Public involvement activities for this plan update included public notices,
stakeholder and public meetings, and the collection of public and stakeholder comments
on the draft plan. In order to ensure socially vulnerable and underserved populations were
included in organizing efforts the Sumner County EMA director located vulnerable areas
within the county and posted survey and meeting invitations. Due to the nature of the
public meetings, neighboring communities, agencies, utilities, academia, civic organizations,
and other interested parties were given the opportunity to participate.
Public notices were posted between 4/10/2023-4/13/2023 on various social media accounts
and throughout the county inviting members of the public to attend the 4/17/2023 Hazard
Mitigation Planning meeting. Documentation to support outreach efforts such as
community flyers, social media postings, and mapping of vulnerable populations can be
found in Appendix A.

Coordination
Early in the planning process, the committee determined that the risk assessment,
mitigation strategy development, and plan approval would be greatly enhanced by inviting
other local and state partners to participate in the process. The coordination involved
contacting these agencies through email, flyers, in-person and phone conversations. All
groups and agencies were advised on how to become involved in the plan development

Coordination with other community planning efforts was also paramount to the success of
this plan. Mitigation planning involves identifying existing policies, tools, and actions that
will reduce a community’s risk and vulnerability to hazards. Sumner County uses a variety
of planning mechanisms such as land development regulations and ordinances to guide
growth and development. Integrating existing planning efforts and mitigation policies and
action strategies into this plan establishes a credible and comprehensive plan that ties into
and supports other community programs.

These and other documents were reviewed and considered, as appropriate, during the
collection of hazard identification, vulnerability assessment, and capability assessment.
Data from these plans and ordinances were incorporated into the risk assessment and
hazard vulnerability sections of the plan as appropriate. The data was also used in
determining the capability of the community in being able to implement certain mitigation
strategies.
Phase II – Risk Assessment
Identify the Hazard, Assess the Risk and Vulnerabilities
The committee completed a comprehensive effort to identify/update, document, and
profile all hazards that have, or could have, an impact on the community. The committee
also conducted a capability assessment to review and document the planning area’s
current capabilities and gaps. By collecting information about existing government
programs, policies, regulations, ordinances, and emergency plans, the committee could
assess the activities and measures already in place that contribute to mitigating some of
the risks and vulnerabilities identified. A more detailed description of the risk assessment
process and the results are included in Chapter 2 Risk and Vulnerability Assessment.
Phase III – Mitigation Strategy
Set Goals and Review Actions
This meeting facilitated brainstorming and discussion sessions that described the purpose
and process of developing planning goals and objectives, a comprehensive range of
mitigation alternatives, and a method of selecting and defending recommended mitigation
actions using a series of selection criteria. This information is included in Chapter 3
Mitigation Strategy.
Draft an Action Plan
A complete first draft of the plan was prepared based on information and input collected
during the HMPC meetings, and various agencies and individuals were invited to comment
on this draft. Public and agency comments were integrated into the final draft for TEMA
and FEMA Region IV to review and approve, contingent upon final adoption by Sumner
County.
Phase IV – Plan Maintenance
Adopt the Plan
To secure buy-in and officially implement the plan, the plan was reviewed and adopted by
the appropriate governing bodies.
Implement, Evaluate, and Revise the Plan
Implementation and maintenance of the plan is critical to the overall success of hazard
mitigation planning and actions. Chapter 4 Plan Integration and Maintenance discusses

incorporating the plan into existing planning mechanisms and how to address continued
public involvement.

1.3 Plan Update
The 2017 Sumner County Hazard Mitigation Plan contained a hazard identification and risk
assessment for each jurisdiction and a corresponding action list aimed at mitigation risk.
Since that time, progress has been made by both the County and incorporated jurisdictions
on the implementation of the mitigation strategy with 1 completed action and 3 in
progress. The HMPC has met annually over the past five years to monitor, implement, and
update the plan. This chapter includes an overview of the approach to updating the plan
and identifies new analyses and information included in this plan update.

1.3.1 The New Plan
The updated plan involved a comprehensive review and revision of each section of the
2023 plan and included an assessment of the success of the County and the incorporated
jurisdictions in evaluating, monitoring, and implementing the mitigation strategy outlined
in the 2023 plan. Only the information and data still valid from the 2017 plan was carried
forward as applicable in this update. The following requirements were addressed during
this plan update process with consideration of the priorities and goals of the Sumner
County Hazard Mitigation Planning Committee:
•
•
•
•
•
•
•
•
•
•
•
•

Consider changes in vulnerability due to action implementation;
Document success stories where mitigation efforts have proven effective;
Document areas where mitigation actions were not effective;
Document any new hazards that may arise or were previously overlooked;
Document NFIP as related to the county and jurisdictions;
Incorporate new data or studies on hazards and risks;
Incorporate new data related to future climate patterns and trend;
Incorporate new capabilities or changes in capabilities;
Incorporate social vulnerability data and vulnerable population information;
Incorporate growth and development-related changes to inventories; and
Incorporate new action recommendations or changes in action prioritization;
Enhanced public outreach and multi-agency coordination efforts.

1.3.2 2017 HMP Strategy Review
During the 2017 update of the Sumner County Hazard Mitigation Plan, the HMPC identified
12 actions as relevant to the county. Of these 12 actions, 1 has been completed, 3 are in
progress, and 8 have not been started. Actions that had not been pursued were discussed
for relevance to the new plan and were either carried over to the 2023 plan or deleted from
the strategy. 11 of these projects were determined to still be viable and will be carried over
or revised in this plan update. Details and the status of all previous actions are in Table 5.

1.4 Multi-Jurisdictional Special Considerations
Hazards Assessment
Most of the natural hazards identified within this plan have an impact on both Sumner
County and the incorporated jurisdictions. Some hazards have a larger impact on the
County rather than the incorporated jurisdictions and vice versa. Impacts of identified
hazards differ the most at the rural and urban interface where flooding can have different
severity levels. Therefore, the flooding section emphasizes the depth, duration, and timing
of severe flooding events. Below is a table that shows whether a hazard will have multijurisdictional impacts.

1.5 Public Participation
Public involvement included press releases, public meetings, and a public comment period
on the draft plan. Organizations representing vulnerable and underserved populations
were contacted in an effort to gain further input from populations most at risk during
hazardous events. The formal meetings for this plan are summarized in Table 3 (Section
1.2.2) discussed early in this chapter. The 4/17/2023 HMPC meeting was open to the public;
and two individuals as well as a representative of a volunteer fire department and a
representative of a local church chose to attend.
Public notices were posted between 4/10/2023-4/13/2023 on various social media accounts
and throughout the county inviting members of the public to attend the 4/17/2023 Hazard
Mitigation Planning meeting. Along with the opportunity to attend the public HMPC
meeting, community members were also invited to be a part of the HMP update process by
completing a short survey via QR that was advertised along with the meeting. The survey
was open for three weeks; only 3 individuals participated in the survey opportunity. The
results are detailed below. Over the past five years, the community was kept involved in
the planning process through the implementation of projects in the plan.

1.6 County Data Profile
1.6.2 Resources and Assets
Sumner Regional Medical Center and Tri-Star Hendersonville Medical Center provide 24hour emergency care to residents of the county and are home to 155 beds and 159 beds,
respectively. The unincorporated county also has: 195 volunteer firefighters, 246 full-tiem
firefighters with 28 stations, and 130 full time Law Enforcement officers including the
county sheriff. Sumner County School District facilities the learning of approximately
29,818 students via their system of 49 schools within the county.
Sumner County houses over 35 radio stations, 7 tv networks, and 9 newspapers. The main
phone companies in the area are AT&T, Verizon, Comcast, and Level 3 Communications
(Gallatin). Residents in the county can either obtain internet via AT&T, Comcast, or Level 3
Communications (Gallatin). Communication resources, a vital component of emergency
response and preparedness, is notably lacking in the more rural portions of Sumner

The Cumberland River cuts through the lower middle portion of the county. Other smaller
waterways and creeks intersect through the county and its incorporated jurisdictions as will
be illustrated throughout the flood hazards section. a further analysis of these water
systems will be explored in the hazard flood section as related to their propensity for flood
events.
The nearest international airport to the county seat, Gallatin, is BNA (approx. 31 miles) and
the closest general aviation locations are Music City Executive and John C Tune Airport.
Given the limited public transportation options and the rural environment of Sumner
County, 48% of working individuals endure a commute of more than 30 minutes and 79%
of all working individuals drive alone to work.
Sumner County is governed by an elected County Executive and County Commissioners.
The jurisdictions withing Sumner County are governed by an elected Mayor and
Commissioners/Alderman. There are multiple regulatory committees that are appointed by
both the County Mayor and the Board of Commissioners.

1.6.3 Development and Growth
Like a majority of its counterparts, Sumner County, has been experiencing rapid growth
over the past few years. The population of the county increased between the 2010 and
2020 censuses from 160,645 to 196,281. 12% of the 72,638 Sumner County households
deal with at least 1 severe housing problem (overcrowding, high housing costs, lack of
kitchen facilities, or lack of plumbing facilities). Most of Sumner Counties’ employed
population work within the services industry and the manufacturing industry. Sumner
County is a member of the Joint Economic and Community Development Boards to ensure
and promote economic growth within the county and for its constituents. As stated,
Sumner County has experienced much growth since the last planning period across all
sectors. It was noted by multiple committee members that new subdivisions were being
built with an increasing population throughout the county as well as new industrial areas.

1.6.4 Demographics
Throughout the planning process, Sumner County HMPC remained committed to
recognizing socially vulnerable and underserved populations. In order to maintain this

1.6.5 Social Vulnerability
Social vulnerability refers to a community’s capacity to prepare for and respond to the
stress of hazardous events ranging from natural disasters, such as tornadoes or disease
outbreaks, to human-caused threats, such as toxic chemical spills. Social vulnerability
considerations were included in this plan update to identify areas across the planning area
that might be more vulnerable to hazard impacts based on several factors. The County

2023 Sumner County Hazard Mitigation Plan

CHAPTER 1: THE PLANNING PROCESS

BEOP will also incorporate this information to improve response efforts in socially
vulnerable neighborhoods.
The Center for Disease Control and Prevention (CDC) has developed a social vulnerability
index (SVI) to measure the resilience of communities when confronted by external stresses
such as natural or human-caused disasters or disease outbreaks. The SVI is broken down
to the census tract level and provides insight into vulnerable populations to assist
emergency planners and public health officials in identifying communities more likely to
require additional support before, during, and after a hazardous event. The SVI index
combines four main themes of vulnerability, which are, in turn, broken down into
subcategories for 16 vulnerability factors. The themes are outlined in the below table and
map.

1.6.6 Critical Infrastructure
Critical Infrastructure are assets in a community that are considered vital to the public’s
health and safety. Due to the sensitivity of these assets in Sumner County and the
incorporated jurisdictions, these assets are restricted for public viewing. However, the data
is viewable to restricted personal on the State of Tennessee’s Critical2TN Database. The
county and incorporated jurisdictions currently have 55 assets identified.

1.7 Resource Capabilities
The committee gathered the following resource capabilities to determine what existing
staff and resources are being used to support mitigation programs.

CHAPTER 1: THE PLANNING PROCESS

Chapter 2: Hazard and Risk Assessment
Risk Assessment Overview
Hazard Mitigation Planning is about developing a strategy to reduce risk in the long term.
An essential part of the process is identifying hazards, risks, impacts and vulnerabilities. In
mitigation planning, “risk” is the potential for damage or loss when a hazard interacts with
an asset. Assets can be people, buildings, infrastructure, the economy, or natural and
cultural resources.
The risk assessment helps communicate vulnerabilities, develop priorities, and inform
decision making. It is the factual basis for the mitigation strategy. The hazards and
associated impacts in the risk assessment should be the hazards and impacts the
mitigation strategy seeks to address. If, for example, the risk assessment shows that the
state will have hurricane damage in a specific area, the mitigation strategy should include
actions to protect state assets and jurisdictions, especially underserved communities, and
socially vulnerable populations, in those areas.

The Sumner County HMPC conducted a hazard identification analysis to determine the
natural and man-made hazards that threaten the County. Existing hazard data from TEMA,
FEMA, the National Oceanic and Atmospheric Administration (NOAA), and other sources
were examined to assess the significance of these hazards to the planning area. Hazard
data from the ETSU Geoinformatics & Disaster Science Lab was also analyzed as related to
the changing weather trends and their significance. Significance was measured in general
terms and focused on key criteria such as frequency and resulting damage, which includes
deaths and injuries, as well as property and economic damage. Any hazard that had two or
more green lifeline categories is considered low risk for damages and therefore, will not be
providing mitigation actions for those specific hazards.
2023 Sumner County Hazard Mitigation Plan

CHAPTER 2: RISK AND VULNERABILITY ASSESSMENT

To further focus on the list of identified hazards for this plan update, the HMPC researched
past events that resulted in a federal and/or state emergency or disaster declaration in
Sumner County to identify known hazards. Table 11 presents a list of all major disaster and
emergency declarations that have occurred in Sumner County since 1953, illustrating which
hazards pose the greatest risk to the County.

2.1 Drought
A. Hazard Overview
Drought is a deficiency in precipitation over an extended period. It is a standard, recurrent
feature of climate that occurs in virtually all climate zones. The duration of droughts varies
widely. In some cases, drought develops relatively quickly and lasts a very short time,
exacerbated by extreme heat and/or wind. There are other cases when drought spans
multiple years or even decades. Studying the paleoclimate record is often helpful in
identifying when long-lasting droughts have occurred. Common types of droughts are
detailed below.
Table 13: Drought Classifications
Type

Details

Meteorological
Drought

Meteorological Drought is based on the degree of dryness (rainfall deficit) and the length
of the dry period.

CHAPTER 2: RISK AND VULNERABILITY ASSESSMENT
Agricultural
Drought
Hydrological
Drought
Socioeconomic
Drought

Agricultural Drought is based on the impacts on agriculture by factors such as rainfall
deficits, soil water deficits, reduced groundwater, or reservoir levels needed for irrigation.
Hydrological Drought is based on the impact of rainfall deficits on the water supply, such
as stream flow, reservoir and lake levels, and groundwater table decline.
Socioeconomic drought is based on the impact of conditions (meteorological, agricultural,
or hydrological drought) on the supply and demand of some economic goods.
Socioeconomic deficiency occurs when the demand for an economic good exceeds the
supply due to a weather-related deficit in the water supply.

The wide variety of disciplines affected by drought, its diverse geographical and temporal
distribution, and the many scales drought operates on make it difficult to develop a
definition to describe drought and an index to measure it. Many quantitative measures of
droughts have been developed in the United States, depending on the discipline affected,
the region being considered, and the particular application. Several indices developed by
Wayne Palmer and the Standardized Precipitation Index help describe the many scales of
drought.
The U.S. Drought Monitor summarizes drought conditions across the United States and
Puerto Rico. Often described as a blend of art and science, the map is updated weekly by
combining a variety of data-based drought indices and indicators and local expert input
into a single composite drought indicator.
The Standardized Precipitation Index (SPI) measures drought, which differs from the
Palmer Drought Index (PDI). Like the PDI, this index is negative for lack and positive for wet
conditions. But the SPI is a probability index that considers only precipitation, while
Palmer's indices are water balance indices that consider water supply (rain), demand
(evapotranspiration), and loss (runoff).
The Palmer Drought Severity Index (PDSI), devised in 1965, was the first drought
indicator to assess moisture status comprehensively. It uses temperature and precipitation
data to calculate water supply and demand, incorporates soil moisture, and is considered
the most effective for unirrigated cropland. It primarily reflects the Perry-term drought and
has been used extensively to initiate drought relief. It is more complex than the SPI and the
Drought Monitor.

B. County Profile
According to the PDSI map shown in Figure 2, Middle Tennessee has a relatively low risk of
drought hazards. However, drought cannot be confined to geographic or political
boundaries, and some areas may experience more severe drought events than what is
shown on the map.

Figure 3 - Drought Monitor Time Series (Source: National Drought Mitigation Center)

Figure 3 above illustrates drought conditions within Sumner County between 2000 and
2023. According to the National Drought Mitigation Center, the last Extreme Drought (D4)
period occurred in 2007. D4 (extreme drought) is categorized by browning grass, low lake
levels, municipality water restrictions, and increased water prices. D0 (abnormally dry)
conditions consist of hard ground and declining agriculture ponds and creeks. A table
containing all NOAA-recorded drought events between 2000 - 2023 for Sumner County is
included in Appendix C.
May 2007 through November 2007 – The drought in this period was felt across the
region, the state experienced close to $750 million in crop losses in 2007 largely attributed
to the drought conditions. The City of Portland was unable to meet the water demands of
the residents and had to use water from other utility districts to meet demands. Voluntary
water restrictions were established across jurisdictions. Within the county corn production

was down approximately 50% and forage hay 1/3 during this period having an effect on
normal market prices.

Figure 4 – 2007 Drought Conditions

Probability Future Events – Occasional
The probability of Sumner County and its municipalities experiencing a drought event can
be challenging to quantify but based on the historical record of 16 droughts since 2000; it
can reasonably be assumed that this type of event could occur every few years.

C. Risk Assessment
Sumner County is vulnerable to drought; however, estimated potential losses are
inherently difficult to calculate because drought tends to cause minor damage to the built
environment. Therefore, it is assumed that all buildings and facilities in the planning area
would technically be exposed to the drought hazard; there is no significant vulnerability to
these buildings on a structural level.
Potential drought losses can be calculated in terms of the value of agriculture in the
County, which is perhaps most vulnerable to drought. According to the USDA, the net
income for agriculture is around $2.6 million. Population growth could contribute directly
to this hazard, as more users pull from the available water supply within the region.
Drought can also increase the County’s vulnerability to wildfires. Dry, hot, and windy

weather combined with dry vegetation and a spark through human intent, accident, or
lightning can start a wildfire.
The National Risk Index is a dataset and online tool to help illustrate the United States
communities most at risk for natural hazards. It was built and designed by FEMA in close
collaboration with various stakeholders and partners in academia; local, state and federal
government. The Risk Index leverages available source data for natural hazards and
community risk factors to develop a baseline relative risk assessment for each county and
census trace. Some of these community risk factors include social vulnerability which is
determined by the data pulled from the Census preformed every ten years. A higher social
vulnerability score is proportional to a higher risk score.
National Risk Index Score for Drought = very low
Although the National Risk Index is a well-valued tool it fails to properly show the feedback
from the participating jurisdictions. Therefore, all identified hazards were evaluated in
regard to risk in FEMA lifelines per jurisdiction. The scenario that local jurisdictions would
evaluate the conditions off of was a mid-level impact of the identified hazard. The results
are below:

As shown in the above table, a majority of the Sumner County HMPC chose to rank
droughts as low risk to the community, however, the committee chose to include the
hazard within the plan to better understand the possible impacts if a drought were to
occur. Portland, a more rural jurisdiction, is more susceptible to the negative impacts of a
drought and thus ranked the risk higher and provides a mitigation action to combat said
risk.

D. Land Use and Development
According to the National Drought Mitigation Center, how we use land affects our
vulnerability to drought. In general, land use patterns that maintain the integrity of
watersheds and that have a smaller paved footprint result in greater resilience in the face
of drought. The projected increase in population will possibly result in an increase in
buildings and infrastructure, leading to increased impervious areas. An increase in
population may also put increasing pressure on water and other natural resources,
particularly during periods of drought. Therefore, future development could impact
drought vulnerability in Sumner County.

E. Multi-Jurisdictional Differences
Due to the nature of drought, Sumner County and the incorporated jurisdictions are equally
susceptible to drought conditions.

2023 Sumner County Hazard Mitigation Plan
32

CHAPTER 2: RISK AND VULNERABILITY ASSESSMENT

F. Summary
Sumner County and all incorporated jurisdictions are equally vulnerable to drought. With
historical frequency considered there is a significant chance of this event occurring each
year. Drought can affect people’s health and safety. Examples of drought impacts on society
include anxiety or depression about economic losses, conflicts when there is not enough
water, reduced incomes, fewer recreational activities, higher incidents of heat stroke, and
even loss of human life. Drought conditions can also provide a substantial increase in wildfire
risk. As plants and trees wither and die from a lack of precipitation, increased insect
infestations, and diseases—all associated with drought—they become fuel for wildfires.
Sumner County periods of drought can equate to more wildfires and more intense wildfires,
which affect the economy, the environment, and society in many ways, such as by destroying
neighborhoods, crops, and habitats.

CHAPTER 2: RISK AND VULNERABILITY ASSESSMENT

2.2 Earthquakes
A. Hazard Overview
An earthquake results from a sudden release of energy in the Earth’s crust that creates
seismic waves. The energy originates from a subsurface fault. A fault is a fracture or
discontinuity in a volume of rock along tectonic plates. In the most general sense, the word
earthquake describes any event that generates seismic waves. Earthquakes are typically
caused by the rupturing of geological faults. Occasionally, they are also caused by other
events such as volcanic activity, landslides, mine blasts, and nuclear tests. An earthquake's
point of initial rupture is called its focus or hypocenter. The epicenter is the point at ground
level directly above the hypocenter.

B. County Profile
Sumner County is near the major intraplate (within a tectonic plate) seismic zone known as
the New Madrid Seismic Zone. The New Madrid Seismic Zone (NMSZ) is an approximately
120-mile-long fault system that stretches across five states, including Western Tennessee.
Sumner County is near the East Tennessee Seismic Zone (ETSZ) which stretches across
three states. The figure below illustrates the risk level of the NMSZ/ETSZ within the state.

Figure 5 New Madrid Seismic Zone (Source: CUSEC)

According to the USGS Earthquake Database, Sumner County has not experienced
earthquakes in the past 20 years. However, given its proximity to the NMSZ and ETSZ the
committee felt it important to profile due to secondary hazard risk.
2023 Sumner County Hazard Mitigation Plan
34

CHAPTER 2: RISK AND VULNERABILITY ASSESSMENT

The NMSZ is known for producing four of the largest North American earthquakes in
recorded history, all of which would have been felt in Sumner County. This includes the
noted three-month period between December 1811 and February 1812 that had at least
four earthquakes which are understood by scientists to be greater than a M7.0. During this
period, there were dozens of strong earthquakes ranging between M6.0 and M7.5.
Thousands of smaller shocks were documented. Similar to the 1811-12 New Madrid
earthquake sequence which created Reelfoot Lake in Lake County, Tennessee, very large
magnitude earthquake sequences are believed to have occurred in pre-historic times as
well. Paleo-liquefaction and geologic evidence suggests large earthquake sequences
occurred in the New Madrid Seismic Zone in 1450 AD and 900AD.
Based on geologic research on the paleo seismic record of past earthquakes, the USGS
estimates that there is a 7 to 10 percent chance of a New Madrid earthquake the size of
those in 1811-12 occurring in the next 50 years. However, the occurrence of even a
moderate-sized earthquake located in close proximity to urban centers such as Memphis
or St. Louis could be locally devastating. The last magnitude-6 earthquake struck near
Charleston, Missouri, in 1895. The chance of such an earthquake occurring in the New
Madrid region in the next 50 years is 25 to 40 percent.
These probabilities are derived from the USGS National Seismic Hazard Maps, which are
developed from geologic information about faults, evidence of prehistoric earthquakes,
instrumental and historical earthquake catalogs generated by seismic monitoring, and
ground deformation measurements. The National Seismic Hazard Maps are used to
estimate probabilities of large earthquakes and the ground shaking to be expected if those
earthquakes occur.
The Eastern Tennessee Seismic Zone (ETSZ), a zone of small earthquakes stretching from
northeastern Alabama to southwestern Virginia. The ETSZ is the second-most active natural
seismic zone in the central and eastern United States, behind the New Madrid Seismic Zone
in the Mississippi River region that produced the 1811-1812 magnitude 7+ earthquakes. In
historic times, the ETSZ has not produced earthquakes larger than magnitude 4.8, however
scientists believe the ETSZ is capable of generating magnitude 6 or greater. The ETSZ region
is home to several nuclear power plants and hydroelectric dams related to the Tennessee
Valley Authority, along with major population centers such as Knoxville and Chattanooga.

Since 1812, the most significant recorded earthquakes from the New Madrid Zone were in
1895 and 1968. Since seismic measurement instruments were installed in and around the
zone in the 1970s, more than 4,000 small earthquakes have been recorded, with the vast
majority being too small to be felt.

Figure 6 NMSZ Earthquakes Recorded Since 1974 (Source: USGS)

According to a 2008 FEMA report, a severe earthquake in the NMSZ could result in the
highest economic loss due to a natural disaster in U.S. history. Based on this report, a 7.7
magnitude quake in the NMSZ would result in thousands of fatalities, hundreds of billions
of dollars in damage to structures, and total disruption of vital infrastructure in Western
Tennessee, including Sumner County.
Probability of Future Events – Unlikely
A catastrophic earthquake at the NMSZ would result in $100-200 million in building
damages. Furthermore, according to the HAZUS, Sumner County will experience the
following in a catastrophic earthquake scenario:

into the following percentage categories: 63.2% residential, 20.8% commercial, 9.9%
industrial, 1% agricultural, 2.8% religious, 0.9% governmental, and 1.5% educational.
Throughout the county, all buildings and infrastructure are vulnerable to earthquake
impacts.

As shown in the above table, the Sumner County HMPC chose to rank earthquakes as low
risk to the community with a majority of the jurisdictions not ranking it as a hazard of
concern. However, they wanted to include the hazard within the plan to better understand
the possible impacts if an earthquake were to occur. Due to the extremely low risk ranking
no mitigation actions will be included for earthquake hazards.

D. Land Use and Development Trends
Heavily populated or industrialized centers are at a higher risk for catastrophic earthquake
damage. Sumner County, like much of Tennessee, is experiencing rapid growth increasing
the likelihood of significant impacts to life and property from a significant earthquake.

E. Multi-Jurisdictional Differences
Counties predominantly in the West Portion of Tennessee will be more likely impacted by
the New Madrid Zone. However, a significant magnitude earthquake can cause primary
and secondary effects across the state.

F. Summary
Due to its proximity to the New Madrid Fault, the entirety of Sumner County could be
subject to an earthquake. This includes the entire County population and all infrastructure.
A significant earthquake event would result in a substantial loss of life and billions of
dollars in damages.

CHAPTER 2: RISK AND VULNERABILITY ASSESSMENT

2.3 Flood
A. Hazard Overview
Flooding events occur when excess water from rivers and other bodies of water overflow
onto riverbanks and adjacent floodplains. In addition, lower-lying regions can collect water
from rainfall, and poorly drained land can accumulate rain through ponding on the surface.
Floods in Sumner County are usually caused by rain and may also be caused by snowmelt
and man-made incidents.
The area adjacent to a channel is the floodplain, as shown in Figure 10. A floodplain is flat or
nearly flat land adjacent to a stream or river that experiences occasional or periodic
flooding. It includes the floodway, which consists of the stream channel and adjacent areas
that carry flood flows, and the flood fringe, which are areas covered by the flood but do not
experience a strong current. Floodplains are made when floodwaters exceed the capacity
of the main channel or escape the channel by eroding its banks. When this occurs,
sediments (including rocks and debris) are deposited that gradually build up over time to
create the floor of the floodplain. Floodplains generally contain unconsolidated sediments,
often extending below the stream’s bed.

Figure 10 Characteristics of a Floodplain (Source: FEMA)

Three general health hazards common to flood events:
1. Floodwaters carry anything on the ground that the upstream runoff picked up,
including dirt, oil, bacteria, animal waste, lawn, farm, and industrial chemicals.
Pastures and areas where farm animals are kept, or their wastes are stored can
contribute to polluted waters in the receiving streams. Floodwaters also saturate
the ground, which leads to infiltration into sanitary sewer lines. When wastewater
treatment plants are flooded, there is nowhere for the sewage to flow. Infiltration
and lack of treatment can lead to overloaded sewer lines that can back up into lowlying areas and homes. Even when flood waters dilute it, raw sewage can be a
breeding ground for bacteria such as E. coli and other disease-causing agents.
2. The second health problem arises after most water has gone. Stagnant pools can
become breeding grounds for mosquitoes, and wet building areas that have not
been adequately cleaned breed mold and mildew. A building that is not thoroughly

2023 Sumner County Hazard Mitigation Plan
42

CHAPTER 2: RISK AND VULNERABILITY ASSESSMENT

cleaned becomes a health hazard, especially for small children and the elderly.
Another health hazard occurs when ducts in a forced air system are not adequately
cleaned after inundation. When the furnace or air conditioner is turned on, the
sediments left in the ducts are circulated throughout the building and breathed in
by the occupants. If the county water system loses pressure, a boil order may be
issued to protect people and animals from contaminated water.
3. The third problem is the long-term psychological impact of having been through a
flood and seeing one’s home damaged and personal belongings destroyed. The cost
and labor needed to repair a flood-damaged home severely strain people, especially
the unprepared and uninsured. There is also a long-term problem for those who
know their homes can be flooded again. The resulting stress on floodplain residents
takes its toll in the form of aggravated physical and mental health problems.

B. County Profile
Riverine flooding occurs from inland water bodies such as streams and rivers. In
Tennessee, flooding is highly dependent on precipitation amounts and is highly variable
within the State.
HAZUS is a regional multi-hazard loss estimation model developed by FEMA and the
National Institute of Building Sciences (NIBS). The primary purpose of HAZUS is to provide a
methodology and software application to develop multi-hazard losses at a regional scale.
These loss estimates would be used primarily by local, state, and regional officials to plan
and stimulate efforts to reduce multi-hazard risks to prepare for emergency response and
recovery.
Table 18 Mapped Flood Insurance Zones

Description

Areas subject to inundation by the 1-percent-annual-chance flood event are
generally determined using approximate methodologies. Mandatory flood
insurance purchase requirements and floodplain management standards
apply.
A 500-year flood zone is a moderate flood hazard area and is an area between
the limits of the base flood and the 0.2- percent-annual-chance (or 500year) flood. Mandatory flood insurance is not required.
Minimal risk areas outside the 1-percent and .2 percent-annual-chance
floodplains.

According to the National Flood Insurance Program, repetitive flood loss is 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. Severe repetitive loss is defined as a facility or structure that has
experienced four or more insurance claims exceeding $5,000 or two claims exceeding the
value of the building. Within the NFIP, flood loss properties are usually considered the most
vital structures to mitigate. The chart below provides a summary of repetitive and severe
repetitive losses for Sumner County in 2019.

Probability of Future Events - Likely
The impact of extreme weather events may increase the frequency and intensity of flash
flooding within Tennessee, particularly in highly urbanized regions such as Memphis,
Nashville, Knoxville, and Chattanooga. Any area with extreme changes in deep terrain,
predominately in East Tennessee, will experience significant flooding impacts.
2023 Sumner County Hazard Mitigation Plan

CHAPTER 2: RISK AND VULNERABILITY ASSESSMENT

Based on a historical record of 68 flood events over 73 years (1950 - 2023), there is a
likelihood for a flood event to occur annually or semiannually. In conjunction with the
future weather projections developed by ETSU Geoinformatics & Disaster Science Lab, it
can be assumed that a flooding event could occur in Sumner County on a BLANK year
basis. Figure X illustrates the projections developed by the ETSU Geoinformatics & Disaster
Science Lab.
Insert: Climate Projection Figure (ETSU)

C. Risk Assessment
The HMPC meeting cited flooding as a repetitive hazard in the county and jurisdictions.
Discussion of commonly flood-prone areas took place, as did mention of improvements that
have already been made to mitigate risks. Future projects were also discussed at this time
and can be found in the Mitigation Action Plan.
The National Risk Index is a dataset and online tool to help illustrate the United States
communities most at risk for natural hazards. It was built and designed by FEMA in close
collaboration with various stakeholders and partners in academia; local, state and federal
government. The Risk Index leverages available source data for natural hazards and
community risk factors to develop a baseline relative risk assessment for each county and
census trace. Some of these community risk factors include social vulnerability which is
determined by the data pulled from the Census preformed every ten years. A higher social
vulnerability score is proportional to a higher risk score.
National Risk Index Score for Flooding = relatively low
Although the National Risk Index is a well-valued tool it fails to properly show the feedback
from the participating jurisdictions. Therefore, all identified hazards were evaluated in
regard to risk in FEMA lifelines per jurisdiction. The scenario that local jurisdictions would
evaluate the conditions off of was a mid-level impact of the identified hazard. The results

Debris Generation
100-year Scenario
The model estimates that a total of XX,XXX tons of debris will be generated. Of the total
amount, Finishes comprises XX% of the total, Structure comprises XX% of the total, and
Foundation comprises XX%. If the debris tonnage is converted into an estimated number of
truckloads, it will require XXX truckloads (@25 tons/truck) to remove the debris generated
by the flood.
500-year Scenario
The model estimates that a total of XX,XXX tons of debris will be generated. Of the total
amount, Finishes comprises XX% of the total, Structure comprises XX% of the total, and
Foundation comprises XX%. If the debris tonnage is converted into an estimated number of
truckloads, it will require XXX truckloads (@25tons/truck) to remove the debris generated
by the flood.
Shelter Requirements
HAZUS estimates the number of households expected to be displaced due to the flood and
the associated potential evacuation. HAZUS also estimates those displaced people that will
require accommodations in temporary public shelters.
100-year Scenario
The model estimates X,XXX households (or X,XXX of people) will be displaced due to the
flood. Displacement includes households evacuated from within or very near to the
inundated area. Of these, XXX people (out of a total population of XX,XXX) will seek
temporary shelter in public shelters.
500-year Scenario
The model estimates X,XXX households (or X,XXX of people) will be displaced due to the
flood. Displacement includes households evacuated from within or very near to the
inundated area. Of these, XXX people (out of a total population of XX,XXX) will seek
temporary shelter in public shelters
Building Related Losses
The building losses are broken into two categories: direct building losses and business
interruption losses. The direct building losses are the estimated costs to repair or replace
the damage caused to the building and its contents. Business interruption losses are the
2023 Sumner County Hazard Mitigation Plan
53

CHAPTER 2: RISK AND VULNERABILITY ASSESSMENT

losses associated with the inability to operate a business because of the damage sustained
during the flood. Business interruption losses also include the temporary living expenses
for those displaced from their homes because of the flood. Total building-related losses
were $XXX.XX million in the 100-year flood scenario and $XXX.XX million in the 500-yr flood
scenario. Table 30 and Table 31 summarize the losses associated with the building damage
in each scenario.

D. Land Use and Development
All future development within the floodplain may be considered at risk. An increase in
population will likely increase the number of buildings and infrastructure. New
development in unincorporated areas could potentially occur in areas prone to flooding
and increase vulnerabilities and potential losses; however, most land use regulations
require the consideration of flooding during the development process.

E. Multi-Jurisdictional Differences
Flooding affects all jurisdictions differently; that is why it is essential to document the
depth, duration, and time that flooding occurred. These differences are noted in past
occurrences to demonstrate the toll that flooding can take on the county’s rural and urban
areas. Due to the topography of Sumner County with its rolling hills and deep valleys, flood

F. Summary
Severe flooding has the potential to inflict significant damage in Sumner County. The total
economic loss estimated for the 100-year riverine flood is $XXX.XX million. The total
economic loss estimated for the 500-year riverine flood is $XXX.XX million. Residential,
commercial, and public buildings and critical infrastructures such as transportation, water,
energy, and communication systems may be damaged or destroyed by flood waters.
During a flood event, chemicals and other hazardous substances may contaminate local
water bodies. Flooding kills animals and, in general, disrupts the ecosystem. Snakes and
insects may also make their way to the flooded areas.

CHAPTER 2: RISK AND VULNERABILITY ASSESSMENT

2.4 Severe Weather
A. Hazard Overview
Thunderstorms
Thunderstorms result from the rapid upward movement of warm, moist air. They can
occur inside warm, moist air masses and at fronts. As the warm, moist air moves upward, it
cools, condenses, and forms cumulonimbus clouds that can reach heights greater than
35,000 ft. Thunderstorms are responsible for developing and forming many severe
weather phenomena, posing significant hazards to the population and landscape. Damage
from thunderstorms is mainly inflicted by downburst winds, large hailstones, and flash
flooding caused by heavy precipitation. Stronger thunderstorms can produce tornadoes
and waterspouts.
Wind
All jurisdictions are vulnerable to receiving damage from severe winds. The NOAA Storm
Data Preparation document categorizes wind into three different types, as defined below.
•

•
•

High Wind: Sustained non-convective winds of 40mph or greater lasting for one
hour or longer or winds (sustained or gusts) of 58 mph for any duration on a
widespread or localized basis.
Strong Wind: Non-convective winds gusting less than 58 mph or sustained winds
less than 40 mph, resulting in a fatality, injury, or damage.
Thunderstorm Wind: Winds arising from convection (occurring within 30 minutes of
lightning being observed or detected), with speeds of at least 58 mph, or winds of
any speed (non-severe thunderstorm winds below 58 mph) producing a fatality,
injury, or damage.

Historically, severe wind events occur multiple times yearly in Sumner County. It is not
unusual for Sumner County to experience winds speeds up to 85 knots (97.8 mph), causing
structural damage, power outages, and downed trees. Based on a historical record of 378
wind events over 72 years (1950- 2022), the historic data suggest and annual occurrence of
a severe wind event.

Hail
Hail forms when updrafts carry raindrops into icy areas of the atmosphere, where they
freeze into ice. Hailstorms occur throughout the spring, summer, and fall but are more
frequent in late spring and early summer. Hailstones are usually less than two inches in
diameter and can fall at speeds of 120 mph. Hail causes nearly $1 billion in damage to
crops and property yearly in the United States. Table 32 provides an overview of the typical
impacts on a community related to hailstone size.

Lightning
Lightning is an electrical discharge between positive and negative regions of a
thunderstorm. Lightning is one of the more dangerous weather hazards in the United
States. Annually, lightning is responsible for deaths, injuries, and millions of dollars in
property damage, including damage to buildings, communications systems, power lines,
and electrical systems. Lightning also causes forest and brush fires and deaths, and injuries
to livestock and other animals. According to the National Lightning Safety Institute,
lightning causes more than 26,000 fires in the United States annually. The institute
estimates property damage, increased operating costs, production delays, and lost revenue
from lightning and secondary effects to be more than $6 billion annually. Impacts can be
direct or indirect. People or objects can be struck or damaged when the current passes
through or nearby.
Winter Weather
A freeze occurs when temperatures are below 32 degrees Fahrenheit for a period. These
temperatures can damage crops, burst water pipes, and create layers of “black ice.” Winter
storms are events that can range from a few hours of moderate snow to blizzard-like
circumstances that can affect driving conditions and impact communications, electricity,
and other services. In Sumner County, all jurisdictions are vulnerable to freezes and
moderate winter storms, but not to the severity level seen in much of the northern U.S.
Based on previous occurrences, Sumner County can experience multiple winter weather
events in one year affecting all jurisdictions equally. The severity of winter storms is
commonly measured by inches of snowfall. It is possible for snowfall to accumulate up to 9
inches in Sumner County and/or ice accumulations to cause hazardous conditions due to
its proximity to and around the mountains. U.S. Mean snowfall per year is from 6-12”
annually average mean snowfall per year is below in Figure 16.

B. County Profile
The entirety of Sumner County is at risk of severe weather. Severe weather events are most
likely in the spring and summer months and during the afternoon and evening hours, but
they can occur year-round and at all hours. In terms of magnitude, the NWS defines
thunderstorms in terms of severity. A severe thunderstorm produces winds greater than
57 miles per hour and/or hail greater than 1 inch in diameter and/or a tornado. The NWS
chose these severity measures as parameters more capable of producing considerable
damage. Hail stones can vary in diameter, and in Tennessee, there have been records of
hail up to 2.75 inches.
Event narratives were obtained via the NOAA Storm Event Database and are included
below for each severe weather category. Tables containing all NOAA-recorded severe
weather events between 1950- 2023 for Sumner County are contained in Appendix C.
Thunderstorms
May 11, 2016 (Rock Bridge): Scattered supercell thunderstorms moved into the area
overnight bringing with them high winds, hail, and heavy rain. The county received
between 3-7 inches of rain in different regions.
May 19, 2017 (White House): Thunderstorms developed during the morning hours and
continued for several hours across the county, over 6 inches of rain were observed in some
areas.
Wind
March 25, 2021 (Corinth): A 4 mile wide by 1 mile long microburst straight-line winds
resulted in severe wind damage. Severeal trees were uprooted landing on homes and
blocking roads. Multiple homes suffered damages as did numerous outbuildings. Four
injuries were reported due to this wind event that reached about 85mph.

March 14, 2012 (Highland Academy): Hail damage occurred to multiple vehicles.
March 3, 2021 (Cherry Mound ARPT): Hail up to 2 inches was reported in the county
Lightning
July 7, 2016 (Millersville): A single family home in Millersville caught fire after being struck
by lightning during a severe storm system.

Figure 18: Home fire after lightning strike July 7, 2016 (Source: WKRN)

Winter Weather
December 8, 2018: Ice accumulations of up to two-tenths of an inch were reported. Icy
precipitation brought down several trees, tree limbs, and powerlines throughout the
northern two-thirds of Sumner County. Icing on roadways also resulted in multiple
accidents.

2023 Sumner County Hazard Mitigation Plan

CHAPTER 2: RISK AND VULNERABILITY ASSESSMENT

Figure 19: Ice on trees in White House December 8, 2018 (Source: NWS)

December 12, 2022: An abnormally cold and strong low-pressure system traveled through
the region in late December bringing with it a blast of Artic air. The strong winds
accompanying the cold temperatures resulted in a wind chill of -15 to -30 degrees
throughout December 24th. The combination of freezing temperatures, wind, and
snowy/icy conditions resulted in treacherous road conditions. SR 6 E was shut down due to
a multi-vehicle crash. Thousands were without power during this event.
Probability of Future Events - Likely
In order to determine the likelihood of future severe weather occurrences in Sumner
County historic data and weather patterns were analyzed. Since 1950, multiple severe
weather events have occurred within the county. In conjunction with the future weather
projections developed by ETSU Geoinformatics & Disaster Science Lab, it can be assumed
that severe weather could occur in Sumner County on a BLANK year basis. Figure X
illustrates the projections developed by the ETSU Geoinformatics & Disaster Science Lab.

C. Risk Assessment
Severe weather is not as spatially defined in any location in Sumner County; therefore, the
entire County is equally at risk of severe weather. This includes the entire County
population, all critical facilities, buildings (commercial and residential), and infrastructure.
The National Risk Index is a dataset and online tool to help illustrate the United States
communities most at risk for natural hazards. It was built and designed by FEMA in close
collaboration with various stakeholders and partners in academia; local, state and federal
2023 Sumner County Hazard Mitigation Plan
61

Commented [AJ5]: Climate Projections

CHAPTER 2: RISK AND VULNERABILITY ASSESSMENT

government. The Risk Index leverages available source data for natural hazards and
community risk factors to develop a baseline relative risk assessment for each county and
census trace. Some of these community risk factors include social vulnerability which is
determined by the data pulled from the Census preformed every ten years. A higher social
vulnerability score is proportional to a higher risk score.
National Risk Index Score for Hail = relatively low
National Risk Index Score for Lightning = relatively low
National Risk Index Score for Strong Wind = relatively moderate
National Risk Index Score for Ice Storm = very high
National Risk Index Score for Winter Weather = relatively low
Although the National Risk Index is a well-valued tool it fails to properly show the feedback
from the participating jurisdictions. Therefore, all identified hazards were evaluated in
regard to risk in FEMA lifelines per jurisdiction. The scenario that local jurisdictions would
evaluate the conditions off of was a mid-level impact of the identified hazard. The results
are below:

Given the information above it becomes vital that all participating jurisdictions are able to
prioritize the necessity of mitigation actions in the following lifeline categories so that they
can become more resilient in the whole community that they serve.

D. Land Use & Development
Increased development and population growth can reasonably translate to increased
damages resulting from severe weather events. The population in Sumner County is
expected to rise similarly to its surrounding counties and Tennessee. An increase in
population will lead to an increase in the number of residential and commercial structures
as well as new and improved infrastructure, which in turn means an increase in the
number and value of assets at risk of wind damage.

E. Multi-Jurisdictional Differences
The entirety of Sumner County and the incorporated jurisdictions, including all assets, can
be considered equally at risk of severe weather events. This includes the entire population,
all critical facilities, buildings (commercial and residential), and infrastructure.

F. Summary
Sumner County is subject to severe weather hazards, including thunderstorms, wind,
lightning, and hail. Associated damages include impacts to utilities, residential and
commercial buildings/property, and agricultural losses. High wind can cause trees to fall
and potentially result in injuries or death; lightning can lead to house fires and serious
injury. Hail can cause injury and severe property damage to homes and automobiles.

CHAPTER 2: RISK AND VULNERABILITY ASSESSMENT

2.5 Tornadoes
A. Hazard Overview
Tornadoes have the potential to produce winds over 200 mph (EF5 on the Enhanced Fujita
Scale) and can be very expansive. Before February 1, 2007, tornado intensity was measured
by the Fujita (F) scale. This scale was revised and is now the Enhanced Fujita scale. Both
scales are wind estimates (not measurements) based on damage. The new scale provides
more damage indicators (28) and associated degrees of damage. Table 34 shows the wind
speeds associated with the enhanced Fujita scale ratings and the damage that could result
at different intensity levels.

According to the Glossary of Meteorology (AMS 2000), a tornado is "a violently rotating
column of air, pendant from a cumuliform cloud or underneath a cumuliform cloud, and
often (but not always) visible as a funnel cloud." Most tornadoes move from southwest to
northeast or west to east.
Although tornadoes can occur in any location, most of the tornado activity in the United
States exists in the Mid-West and Southeast. An exact season does not exist for tornadoes;
however, most occur between early spring and mid-summer (February – June). The onset of
tornado events is rapid, giving those in danger minimal time to seek shelter. The current
average lead time, according to NOAA, is 13 minutes. A tornado can reach wind speeds of
40 mph to 250 mph and higher. The following map illustrates the frequency of tornadoes in
Tennessee.

were included as expanded narratives. A table containing all NOAA-recorded tornadoes
between 1950- 2023 for Sumner County is contained in Appendix C.
April 7, 2006: An F3 Tornado traveled through Davidson and Sumner County for a total
path length of 22.75 miles. 7 deaths were directly attributed to the tornado and 1 was
considered an indirect death. 700 homes and business were damaged or destroyed as a
result of the F3 tornado and an estimated $69 million in damages occurred.
February 5, 2008: Known as the ‘Super Tuesday” tornado outbreak, three tornadoes
touched down in the county (EF-3, EF-1, EF-0). The EF-3 that touched down in the county left
a 50.32 mile long track through 5 counties including Sumner. 85 homes were destroyed, a
post office was destroyed, and 102 trees were uprooted. The tornadic storm directly killed
7 individuals and injured a further 14. The storm also took the roof off of Wynnewood, the
counties only National Historic Landmark, and shifted the foundation.

CHAPTER 2: RISK AND VULNERABILITY ASSESSMENT

December 11, 2021: An EF-1 tornado with a total path length of 6.82 miles touched down
in Old Hickory and traveled to Mt. Juliet, leaving numerous trees uprooted, homes with roof
damage, and damaged outbuildings in its path.
Probability of Future Events - Likely
Historical data and weather patterns were analyzed to determine the likelihood of future
tornado occurrence in Sumner County. Since 1950, 44 tornadoes have occurred within the
county. In conjunction with the future weather projections developed by ETSU
Geoinformatics & Disaster Science Lab, it can be assumed that a tornado could occur in
Sumner County on a BLANK year basis. Figure X illustrates the projections developed by
the ETSU Geoinformatics & Disaster Science Lab.

C. Risk Assessment
The entirety of Sumner County can be considered at risk for a tornado. This includes the
entire County population, all critical facilities, buildings (commercial and residential), and
infrastructure. Tornadoes tracked in Tennessee predominantly travel in a northeasterly
direction in the state. While all assets are considered at risk from this hazard, a particular
tornado would only cause damages along its specific track.
The National Risk Index is a dataset and online tool to help illustrate the United States
communities most at risk for natural hazards. It was built and designed by FEMA in close
collaboration with various stakeholders and partners in academia; local, state, and federal
government. The Risk Index leverages available source data for natural hazards and
community risk factors to develop a baseline relative risk assessment for each county and
census trace. Some of these community risk factors include social vulnerability which is
determined by the data pulled from the Census preformed every ten years. A higher social
vulnerability score is proportional to a higher risk score.
National Risk Index Score for Tornado = relatively high
Although the National Risk Index is a well-valued tool it fails to properly show the feedback
from the participating jurisdictions. Therefore, all identified hazards were evaluated in
regard to risk in FEMA lifelines per jurisdiction. The scenario that local jurisdictions would
evaluate the conditions off of was a mid-level impact of the identified hazard. The results
are below:

Little to No Impact, No Outside Resources Required

Given the information above it becomes vital that all participating jurisdictions are able to
prioritize the necessity of mitigation actions in the following lifeline categories so that they
can become more resilient in the whole community that they serve.

D. Land Use and Development Trends
Sumner County codes include proper wind strength and safety regulations consistent with
state and federal regulations. While the adopted code provides adequate protection, older
and mobile homes are highly susceptible to tornado events. The county has multiple
mobile home areas within the county that are more susceptible to the damaging impacts of
tornadic weather.

E. Multi-Jurisdictional Differences
The entirety of Sumner County and its incorporated jurisdictions are at risk for a tornado
event; however, historically, a large portion of tornado events have taken place at or below
the middle region of the county. It is also worth noting that given the county’s sizeable rural
component, some tornadic events may have gone unreported.

F. Summary
This includes the entire County population, all critical facilities, buildings (commercial and
residential), and infrastructure. While all assets are considered at risk from this hazard, a
tornado would only cause damages along its specific track. The weakest tornadoes, EF0,
can cause minor roof damage, and stronger tornadoes can destroy frame buildings and
badly damage steel reinforced concrete structures. Given the strength of the wind impact
and construction techniques, buildings are vulnerable to direct impact, including potential
destruction, from tornadoes and wind debris that tornadoes turn into missiles. Structures
constructed of light materials such as mobile homes are most susceptible to damage.

CHAPTER 3: MITIGATION STRATEGY

Chapter 3. Mitigation Strategy
3.1 Mitigation Goals
Goals are general guidelines that explain what is to be achieved. They are usually broadbased policy-type statements, long-term, and represent global visions. Goals help define
the benefits that the plan is trying to achieve.
Goal Setting Exercise
In 2017, the HMPC agreed upon the goals for their hazard mitigation plan. It was decided
that the goals from the 2017 plan should be carried over into the 2023 plan. They still
reflect the current hazards and current conditions in the community.
Resulting 2023 Plan Update Goals
At the end of the meeting, the HMPC agreed upon three general goals for planning efforts.
Those goals are as follows:
Goal 1: Protect the Lives and health of citizens from the effects of natural hazards.
Goal 2: Emphasize mitigation planning to decrease vulnerability to new and existing
structures.
Goal 3: Encourage public support and commitment to hazard mitigation by
communicating mitigation benefits.

3.3 Compliance with NFIP
Sumner County, Hendersonville, Westmoreland, White House, Portland, Gallatin,
Goodlettsville, and Millersville participate in FEMA’s National Flood Insurance Program
(NFIP). Each participating community enforces a flood damage prevention ordinance that
regulates development within the Special Flood Hazard Area (SFHA). Additionally, as
members of FEMA’s NFIP, each community requires Elevation Certificates on all new
buildings and substantial improvements within the SFHA.
Given the flood hazards in the planning area, an emphasis will be placed on continued
compliance with the NFIP. The below table lists the Ordinance Adoption dates and citations
for each NFIP jurisdiction in the county.

The State National Flood Insurance Program Office hosts monthly webinars to review and
educate entities on NFIP, each jurisdictional representative is invited and encouraged to
attend. Each participating community will take the following steps to meet or exceed the
following minimum requirements as set by the NFIP:
•
•
•
•

Issuing or denying floodplain development/building permits;
Inspecting all development to ensure compliance with the local ordinance;
Maintaining records of floodplain development;
Assisting in the preparation and revision of floodplain maps;

•

Helping residents obtain information on flood hazards, floodplain map data, flood
insurance, and proper construction measures.

3.4 Prioritization Process
The prioritization process was necessary as most mitigation projects represent a significant
investment of financial and personal resources. By evaluating each project’s degree of
feasibility and the level of costs versus benefits, Sumner County could determine which
projects should include based on the available funding and time. The HMPC used the SAFET method to prioritize these projects. This approach was adopted from the successful
methodology used by other counties in FEMA Region 4. This rating system uses five
variables to evaluate each project's overall feasibility and appropriateness. Figure 25 further
explains this method.

Figure 25 SAFE-T Project Prioritization

The identification and analysis process of mitigation alternatives allowed the HMPC to come
to a consensus and prioritize recommended mitigation actions. The HMPC discussed the
contribution of the effort to save lives or property first and foremost, with additional
consideration given to the benefit-cost aspect of a project; however, this was not a
quantitative analysis. The team agreed that prioritizing the actions collectively enabled the
actions to be ranked in order of relative importance and helped steer the development of
additional actions that meet the more essential objectives while eliminating some of the
actions which did not garner much support. The cost-effectiveness of any mitigation
alternative will be considered in greater detail by performing benefit-cost project analyses
when seeking FEMA mitigation grant funding for eligible actions associated with this plan.

CHAPTER 3: MITIGATION STRATEGY

3.5 Mitigation Action Plan
The Mitigation Action Plan was developed to present the recommendations developed by
the HMPC for how the communities can reduce the risk and vulnerability of people,
property, infrastructure, and natural and cultural resources to future disaster losses.
Emphasis was placed on both future and existing development. The action plan
summarizes who is responsible for implementing each of the prioritized actions and when
and how the actions will be implemented. Due to funding availability and other criteria, it
should be clarified that the actions included in this mitigation strategy are subject to
further review and refinement, alternatives analyses, and reprioritization. This document
does not obligate Sumner County and the incorporated jurisdictions to implement any or
all of these projects. Rather this mitigation strategy represents the desires of the
community to mitigate the risks and vulnerabilities from identified hazards.

CHAPTER 4: IMPLEMENTATION, INTEGRATION, AND MAINTENANCE

Chapter 4. Implementation, Integration, and Maintenance
This section provides an overview of the overall plan implementation, integration and
maintenance strategy and outlines the method and schedule for monitoring, evaluating,
and updating the plan. This section also discusses incorporating the plan into existing
planning mechanisms and how to address continued public involvement.

4.1 Plan Adoption, Implementation, Monitoring, and Evaluation
4.1.1 Plan Adoption
The purpose of formally adopting this plan is to secure buy-in, raise awareness of the plan,
and formalize the plan’s implementation. This plan will be adopted by the appropriate
governing body for each participating community. Copies of the executed resolutions are
shown below.
Note to Reviewer: Executed resolutions will be inserted when they become available.

4.1.2 Implementation
Implementation and maintenance of the plan is critical to the overall success of hazard
mitigation planning. This section provides an overview of the overall strategy for plan
implementation and maintenance.
Mitigation is most successful when it is incorporated into the day-to-day functions and
priorities of the government. Implementation will be accomplished by adhering to the
schedules identified for each action and through constant, pervasive, and energetic efforts
to network and highlight the multi-objective benefits to each program and the community.
This effort is achieved through the routine actions of monitoring agendas, attending
meetings, and promoting a safe, sustainable community. Additional mitigation strategies
could include consistent and ongoing enforcement of existing policies and vigilant review
of programs for coordination and multi-objective opportunities.
Simultaneous to these efforts, it is important to maintain constant monitoring of funding
opportunities that can be leveraged to implement some of the more costly actions. This will
include creating and maintaining a list of ideas on how to meet local match or participation
requirements. When funding does become available, the communities will be able to
capitalize on the opportunity due to the diligence of the HMPC. Funding opportunities to be
monitored include special pre- and post-disaster funds, state and federal funds, benefit
assessments, and other grant programs, including those that can serve or support multiobjective applications.
Elected officials, officials appointed to head community departments and community staff
are charged with the implementation of various activities in the plan. Recommendations
will be made to modify timeframes for the completion of activities, funding resources, and
responsible entities. On an annual basis, the priority standing of various activities may also
be changed. Some activities that are found unachievable may be removed from the plan
2023 Sumner County Hazard Mitigation Plan
82

CHAPTER 4: IMPLEMENTATION, INTEGRATION, AND MAINTENANCE

entirely and activities addressing problems unforeseen during plan development may be
added.

4.1 Integration into Local Planning Mechanism
A vital implementation mechanism that is highly effective and low-cost is the incorporation
of the Hazard Mitigation Plan recommendations and their underlying principles into other
plans and tools. All plan participants will use existing methods and programs to implement
hazard mitigation actions where possible. As previously stated, mitigation is most
successful when it is incorporated into government and public service's day-to-day
functions and priorities. This plan builds upon the momentum developed through previous
and related planning efforts and mitigation programs and recommends implementing
actions, where possible, through these other program mechanisms. These existing
mechanisms include:
•
•
•

Regularity Capabilities
Administrative Capabilities
Fiscal Capabilities

For further information regarding the different capabilities refer to Chapter 3 – Mitigation
Strategy.
Implementation and incorporation into existing planning mechanisms will be conducted by
respective planning authorities and will be done through the routine actions of:
•
•
•
•

Monitoring other planning/program agendas;
Attending other planning/program meetings;
Participating in other planning processes; and
Monitoring community budget meetings for other community program
opportunities.

The successful implementation of this mitigation strategy will require constant and vigilant
review of existing plans and programs for coordination and multi-objective opportunities
that promote a safe, sustainable community. Efforts should continuously be made to
monitor the progress of mitigation actions implemented through other planning
mechanisms. Where appropriate, priority actions should be incorporated into Hazard
Mitigation Plan updates.

4.2 Monitoring, Evaluating, Updating
For the Hazard Mitigation Plan update review process, the Sumner County Emergency
Management Agency Director will be responsible for facilitating, coordinating, and
scheduling reviews and maintenance of the plan. The review of the Hazard Mitigation Plan
will be conducted as follows:
•

The Sumner County Emergency Management Agency will be responsible for leading
the meeting to review the plan.

2023 Sumner County Hazard Mitigation Plan
83

CHAPTER 4: IMPLEMENTATION, INTEGRATION, AND MAINTENANCE

•

•
•

•
•

Notices will be emailed to the members of the HMPC, federal, state, and local
agencies, non-profit groups, local planning agencies, and representatives of
business interests, neighboring communities, and others advising them of the date,
time, and place for the review.
Local City officials will be notified by email or phone call.
Before the review, department heads and others tasked with implementing various
projects/actions will be queried concerning progress in their area of responsibility
and asked to present a report at the review meeting.
A copy of the current plan will be available for public comment.
After the review meeting, a status report will be developed outlining the
implementation of projects over the past year.

Criteria for Annual Reviews
The criteria recommended for annual reviews will include the following:
•
•
•
•
•

•
•
•
•

•

•

Community growth or change in the past year to include residential, commercial,
and industrial growth trends.
The number of substantially damaged or improved structures by flood zone and
review of jurisdictional NFIP membership.
Renovations to public infrastructure, including water, sewer, drainage, roads,
bridges, gas lines, and buildings.
Natural hazard occurrences that required activation of the Emergency Operations
Center (EOC) and whether the event resulted in a presidential disaster declaration.
Natural hazard occurrences that were not of a magnitude to warrant activation of
the EOC or a federal disaster declaration but were severe enough to cause damage
in the community or closure of businesses, schools, or public services.
The dates of hazardous events, narratives, and documented damages.
Closures of places of employment or schools and the number of days closed.
Road or bridge closures due to the hazard and the length of time closed.
Assessment of the number of private and public buildings damaged and whether
the damage was minor, substantial, major, or if buildings were destroyed. The
assessment will include residences, mobile homes, commercial structures, industrial
structures, and public buildings, such as schools and public safety buildings.
Review of any changes in federal, state, and local policies to determine the impact of
these policies on the community and how and if the policy changes can or should be
incorporated into the Hazard Mitigation Plan.
Review of the implementation status of projects/actions (mitigation strategies). The
reason for delay will be discussed for any projects that are behind schedule or not
yet started.

4.2.1 Continued Public Involvement
Continued public involvement is imperative to the overall success of the plan’s
implementation. The update process provides an opportunity to solicit participation from
2023 Sumner County Hazard Mitigation Plan
84

CHAPTER 4: IMPLEMENTATION, INTEGRATION, AND MAINTENANCE

new and existing stakeholders, publicize mitigation success stories, and seek additional
public comment. The plan maintenance and update process will include continued public
and stakeholder involvement and input through attendance at designated committee
meetings, web postings, press releases to local media, and public hearings.
Public Involvement Process for Annual Reviews
The public will be notified via the Sumner County website or any other form of a publicized
social platform (i.e., local newspaper, Facebook, Twitter) well in advance of any public
meetings or comment periods.
Public Involvement for Five-year Update
When the HMPC reconvenes for the five-year update, they will coordinate with all
stakeholders participating in the planning process—including those that joined the
committee since the planning process began—to update and revise the plan. In
reconvening, the HMPC will develop a plan for public involvement and will be responsible
for disseminating information through various media channels detailing the plan update
process. As part of this effort, public meetings will be held, and public comments will be
solicited on the plan update draft.
