MEMORANDUM FOR THE RECORD
Date: December 31, 2025
Subject: Correction to Hazard Ranking in Grapevine Annex — Tarrant County Hazard Mitigation Action Plan
Purpose:
This memorandum documents a correction to the hazard ranking table contained in Grapevine's annex to the
Tarrant County Hazard Mitigation Plan (HAZMAP). The HAZMAP is a FEMA-approved document that outlines
how member jurisdictions will address known hazards and mitigate their effects to the lowest possible level: This
plan is required for jurisdictions to remain eligible for Federal Hazard Mitigation Assistance grants.
Background:
During a review of Grapevine's annex, it was identified that the hazard ranking for drought in the table on page
11 contains an error. The table currently lists the hazard ranking as "8." However, the appropriate ranking should
be "5," consistent with the overall drought hazard ranking shown on page 8 of the same annex.
Correction:
The correct hazard rankings for Grapevine, as reflected in the HAZMAP, are as follows:
1. Tornado
2. Thunderstorm
3. Flooding
4. Winter Storm
5. Drought
6. Wildfire
7. Extreme Heat
8. Expansive Soils
9. Earthquake
These rankings supersede any conflicting information contained in the original document.
Action:
This memorandum will be attached to Grapevine's annex and submitted to Tarrant County Office of Emergency
Management fo inclusion in their official records.

TARRANT COUNTY HAZARD MITIGATION ACTION PLAN
Chapter 2: Planning Process
(In compliance with 201.6(c)(1))
Development and Adoption Process
To apply for federal aid for technical assistance and post -disaster funding, local jurisdictions must comply
with Part 201.3 of the Disaster Mitigation Act of 2000 (DMA 2000), implemented in the Code of Federal
Regulations 44 CFR Part 201.6. Although the City of Grapevine has historically implemented measures to
reduce vulnerability to some hazards, the passage of DMA 2000 helped City officials recognize the
benefits of a long-term approach to hazard mitigation. This approach is achieved by gradually decreasing
hazard -associated impacts by implementing a hazard mitigation action plan (HazMAP). The City's
involvement in the Tarrant County HazMAP represents the collective efforts of the Hazard Mitigation
Planning Team (HMPT), participating Local Planning Teams (LPTs), the public, and stakeholders.
The City developed this annex in accordance with Part 201.6(c)(5) of DMA 2000. The HazMAP and this
annex identify hazards and mechanisms to minimize damage associated with these hazards.
Organizing the Planning Effort
A comprehensive approach was taken to develop the HazMAP. An open involvement process was
established for the public and all stakeholders, allowing everyone to be involved in the planning process
and express their views. The public meeting was advertised with notices in the local newsletter and on
social media.
Two teams worked simultaneously on this Tarrant County HazMAP:
Hazard Mitigation Planning Team (HMPT): This team consisted of points of contact from each
participating jurisdiction. The HMPT met to discuss county -wide topics, including hazards and
mitigation strategies. The points of contact were the leads of their LPT.
2. Local Planning Team (LPT): Each jurisdiction had an LPT that consisted of the Emergency
Management Coordinator for that jurisdiction and designated representatives from that jurisdiction.
This team met to assess the jurisdiction's capabilities, hazards, and mitigation strategies.
Local Planning Team
This annex to the Tarrant County HazMAP was developed by the City of Grapevine's LPT. The efforts of
the LPT were led by the City's Emergency Management Coordinator. The LPT was assembled in 2020
with representatives from the City of Grapevine.

TARRANT COUNTY HAZARD MITIGATION ACTION PLAN
Profiles of Natural Hazards
The City of Grapevine's LPT ranked potential hazards in order of risk, with Thunderstorm being the
highest (see Table 4). Risk, for the purposes of hazard mitigation planning, is the potential for damage or
loss created by the interaction of natural hazards with community assets. If a natural hazard could not
impact the City of Grapevine, not applicable (N/A) is used as its rank and its reasoning is noted in the
hazard profile section of this chapter.

Drought, earthquakes, expansive soils, extreme heat, thunderstorms, tornadoes, and winter storms do
not have geographic boundaries and can impact the entire county, including all participating jurisdictions.
Wildfires can threaten rural and urban jurisdictions with undeveloped land. Flooding is a severe threat to
jurisdictions containing 100-year floodplains or bodies of water.
City of Grapevine 9

The following hazards are listed in alphabetical order and describe the location and extent of each
hazard, details of previous occurrences, probability data on future events, and vulnerability to each
hazard.

TARRANT COUNTY HAZARD MITIGATION ACTION PLAN
Drought
Overviev�
The City of Grapevine receive approximately 70% of its drinking water from the Trinity River Authority,
which is supplied by Cedar Creek Reservoir and Richland Chambers Reservoir. The other 30% of
Grapevine's water comes from the city's water supply, Lake Grapevine, which has a normal conservation
pool elevation of 535 feet. Irrigation or watering of any lawn or landscape is prohibited between the hours
of 10:00 a.m. and 6:00 p.m. The city's Drought Contingency Plan Ordinance is outlined in Chapter 25,
Article V, Section 25-140 of the Code of Ordinances.
Table 6: Drought Hazard Profile for the City of Grapevine
Geographic Area Affected Extensive
Probability of Future Occurrence Likely
Maximum Probable Extent Minor
Potential Impact • Property damage Loss of water supply
• Increase in grassfire potential and intensity
• Negative impact on citizens, including water restrictions and
lack of drinkable water supply
• Impact on car washes, parks, and pools
Vulnerabilities There are no historical data for drought damage in the city. All
populations, economy, structures, improved property, critical
facilities and infrastructure, and the natural environment are
exposed to this hazard. Rises in water costs would affect the
population living below the poverty line.
Summary
The entire the City of Grapevine is vulnerable to drought. Considering its historical frequency, there is a
significant chance of droughts 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.
City of Grapevine 11
TARRANT COUNTY HAZARD MITIGATION ACTION PLAN
Earthquake
Overviev�
The City of Grapevine has experienced zero earthquakes in the past 20 years. However, there is still a
risk, and it would be catastrophic for all populations and assets in the community.
Table 7: Earthquake Hazard Profile for the City of Grapevine
Geographic Area Affected Negligible
Probability of Future Occurrence Unlikely
Maximum Probable Extent Minor
Potential Impact • Injury or death
• Property and infrastructure damage
• Water contamination or loss from broken pipes
• Transportation and communication disruption or damage
• Increase in traffic accidents
• Building collapse
• Natural gas leak Displaced residents
• Power outages
• Damage to the natural environment, including protected
species and critical habitats
Vulnerabilities All populations, economy, structures, improved property, critical
facilities and infrastructure, and the natural environment are
exposed to this hazard, though impacts are undetermined due the
lack of historical data.
Summary
The City of Grapevine could be subject to an earthquake, but none has been reported. A significant
earthquake event would cause a substantial loss of life and billions of dollars in damage to critical
infrastructure.
12 City of Grapevine
TARRANT COUNTY HAZARD MITIGATION ACTION PLAN
Expansive Soils
Gverviev&
All the roadways in the City of Grapevine are subject to damage from expansive soils, and the City
spends thousands of dollars a year on road repairs. However, due to the manner in which data for
expansive soils are collected, it is not clear how many of these repairs are due to damage from expansive
soils.
Table 8: Expansive Soils Hazard Profile for the City of Grapevine
Geographic Area Affected Extensive
Probability of Future Occurrence Occasional
Maximum Probable Extent Medium
Potential Impact • Property damage from foundation damage
• Water contamination or loss from broken pipes
• Building and infrastructure damage
• Road damage
• Transportation delays due to road condition
• Damage to utility lines
Vulnerabilities Because of the manner in which data for expansive soils are
collected, the exact amount of damage in the city was
unavailable, as only road data are available. Expansive soils are
a major consideration for all existing and future structures. All
populations, economy, structures, improved property, critical
facilities and infrastructure, and the natural environment are
exposed to this hazard.
Summary
The nature of expansive soils makes it difficult to predict the locations and the impacts that they might
have. The City has seen impacts on critical assets in the public infrastructure.
City of Grapevine 13
TARRANT COUNTY HAZARD MITIGATION ACTION PLAN
Extreme Heat
Overview
Approximately 13.1 % of the population of the City of Grapevine is 65 years old or older, and
approximately 5.7% lives below the poverty line. Individuals in vulnerable or underserved populations are
not only more likely to experience the effects of extreme temperatures, but they are also likely to be
impacted to a higher degree than their counterparts. In addition, various City facilities have experienced
heat -related power failure, making critical facilities vulnerable.

Vulnerabilities Although extreme heat poses a serious threat to any population,
issues with housing and mobility could make it difficult for the
elderly to seek shelter in response to such a threat. The elderly,
homeless, and outdoor laborers need to take proper precautions.
People should stay indoors to prevent heatstroke; elderly people
who cannot afford air-conditioning are at greatest risk. The
elderly, very young people, and people with poor health are most
at risk of extreme heat.
Summan
The City of Grapevine is vulnerable to extreme temperatures, which can affect people's health and safety.
Therefore, it is essential to have proper measures in place to prevent critical structures from being
vulnerable to utility failure during extreme temperatures.

Flooding
averviev�
Since 2019, there have been no flash flooding events recorded by NOAA, However, flooding events still
occur in the city which cause public safety and transportation issues. According to the City of Grapevine,
there are six public wastewater lift stations in the 100-year floodplain.
Table 10: Flooding Hazard Profile for the City of Grapevine
Geographic Area Affected Limited
Probability of Future Occurrence Occasional
Maximum Probable Extent Medium
Potential Impact • Loss of electricity
• Loss of, or contamination of, water supply
• Loss of property
• Structure and infrastructure damage — flooded structures and
eroded roads
• Displaced residents
• Snakes migrate and mosquitoes increase
• Fire — as a result of loss of water supply
• Debris in transportation paths
• Emergency response delays
• Disruption of traffic can lead to impacts on the economy.
• Damage to the natural environment, including protected
species and critical habitats
Vulnerabilities Based on historical data, flooding has caused zero injuries and
fatalities per year and is expected to have the same results in the
future. Commuters and any buildings in a floodplain are the most
at risk. All future development in the floodplain may be at risk. An
increase in population will likely increase the number of buildings
and infrastructure. New development in unincorporated areas
could 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.
• Past damage done to jurisdictional roads and critical infrastructure due to flooding: DR-4223,
May/June 2015, throughout the incident period, severe continuous rains caused flooding in and
around Grapevine Lake. Eight public lake parks and the Grapevine Golf Course experienced flooding
which resulted in approximately $3.1 million in damage and repair costs. Dove Road was closed near
Silvercrest Lane. The Grapevine City Council estimated rebuilding efforts would take months.
• Intersections or traffic routes impacted by flooding: Farm to Market 2499 (Northeast), State
Highway 121 service roads (Northeast), Lake Ridge at Kimball (Northwest), and Fairway Drive
City of Grapevine 15
TARRANT COUNTY HAZARD MITIGATION ACTION PLAN
(Northwest) (emergency spillway for Grapevine Dam). See low-water crossings below, as these roads
have the potential of flooding.
• Names of creeks or rivers that flood: Denton Creek and Bear Creek.

Commercial 2,307.76 256.56 11.12%
Total 7,287.37 635.24 8.72%
Source: Grapevine Geographic Information Systems (GIS).
• Low -Water Crossings: A low-water crossing provides a type of bridge when water flow is low. Under
high -flow conditions, water runs over the roadway and precludes vehicular and pedestrian traffic.
These crossings can be dangerous when flooded.
LOW-WATER CROSSING TYPES DEFINED
• Bridges are open -bottomed structures with elevated decks. They may be designed with one or
several piers. Low-water bridges generally have greater capacity and are able to pass higher flows
underneath the driving surface than most vented and unvented fords.
• Vented fords have a driving surface elevated above the streambed, with culverts (vents) that enable
low flows to pass beneath the roadbed. The vents can be one or more pipes, box culverts, or open -
bottomed arches. In streams carrying large amounts of debris, the driving surface over the vent may
be removable, permitting the debris to be cleared after a large flow event.
Compliance with the National Flood Insurance Program
Participation in the National Flood Insurance Program (NFIP) is based on a voluntary agreement between
a community and the Federal Emergency Management Agency (FEMA). For communities that adopt a
floodplain management ordinance to reduce flood risks to new construction, federally backed flood
insurance is made available to property owners in the community. Compliance with the NFIP. However,
extends beyond mere participation in the program. The NFIP has three basic components: 1) floodplain
identification and mapping risk, 2) responsible floodplain management, and 3) flood insurance. The City
of Grapevine participates in the NFIP and provides details about the community and its participation
below. The following information was requested:

Thunderstorm
Overview
In the City of Grapevine, past damage from thunderstorms, and specifically hail has caused
approximately $10,000,000 in damage in the City of Grapevine.
Table 14: Thunderstorm Hazard Profile for the City of Grapevine
Geographic Area Affected Extensive
Probability of Future Occurrence Highly Likely
Maximum Probable Extent Medium
Potential Impact • Property damage to fences, vehicles, equipment, and roofs
• Transportation delays
• Injuries and deaths
• Debris from trees and damaged property
• Electrical grid problems
• Communication problems — phone and internet lines down
• Damage to the natural environment, including protected
species and critical habitats
Vulnerabilities Given the dynamic nature of thunderstorms, all populations,
economy, structures, improved property, critical facilities and
infrastructure, and the natural environment are exposed to this
hazard. Although thunderstorms pose a serious threat to any
population, issues with mobility could make it difficult for the
elderly to evacuate ahead of such a threat or relocate after a
damaging hailstorm has occurred. In addition, power failures
could affect medical equipment needed by the elderly or
populations with functional and access needs.
Summary
The City of Grapevine is subject to severe weather hazards, including thunderstorms, wind, lightning, and
hail. Associated damage includes impacts on utilities, residential and commercial buildings/property, and
agricultural losses. High wind can cause trees to fall and cause injuries or death; lightning can lead to
house fires and serious injuries. Hail can cause injury and severe damage to homes and automobiles.

Tornado
Overview
In the City of Grapevine, there have been two reports of a tornado since 2020. An EF-1 tornado moved
through Grapevine beginning near the Mustang Elite Car Wash on Ira E Woods Avenue south of Highway
114. The tornado crossed Ira E Woods Avenue, causing significant roof damage to businesses. The
tornado continued moving northeast, damaging trees and shingles in a residential area. The tornado next
caused damage to two HVAC units at Grapevine Middle School. The next notable damage was to the
Grapevine Service Center, which had significant roof damage and several garage doors were blown out.
The tornado continued through a residential area where it caused minor damage to several trees and
roofs. However, it damaged several large trees at the Grapevine Cemetery. Maximum estimated winds
were 110 mph. The same day, another EF-1 tornado damaged parts of Grapevine Mills Mall, including
portions of the roof, paneling, and walls and HVAC units on the roof. The tornado tracked north, where it
damaged some residential roofs. Maximum estimated winds were 100 mph.

critical facilities, critical infrastructure, improved property, and the
entire population of the City is exposed to this hazard.
SI immar)
The entire population, all critical facilities, buildings (commercial and residential), and infrastructure are
vulnerable to tornadoes. Although all assets are considered at risk from this hazard, a tornado would only
cause damage along its specific track. The weakest tornadoes, EFO, can cause minor roof damage, and
stronger tornadoes can destroy frame buildings and badly damage steel -reinforced concrete structures.
City of Grapevine 21
TARRANT COUNTY HAZARD MITIGATION ACTION PLAN
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.

Winter Storm
Overview
Bridges and overpasses can be impacted by winter storms. The bridges at Dove Road, Pool Road,
Gaylord Texan Bridge, Ruth Wall, and Texan Trail, and Scribner at Northwest Highway are considered
most vulnerable. State highway flyovers and overpasses are managed by the Texas Department of
Transportation. Vehicle crashes are likely in these areas and there might be traffic issues because drivers
must slow down to navigate iced -over bridges. There would be delays in emergency response and an
increase in life -safety concerns.

Chapter 4: Capabilities Assessment
(In compliance with 201.6(c)(3))
This capability assessment examines the City's ability to implement and manage a comprehensive
mitigation strategy. The jurisdiction's strengths, weaknesses, and resources are identified to develop an
effective HazMAP. The capabilities identified in this assessment were evaluated collectively to develop
feasible recommendations to support the implementation of effective mitigation activities.
To initiate this assessment, a questionnaire was distributed to the City of Grapevine's LPT. It included
questions regarding existing plans, policies, and regulations that contribute to or hinder the ability to
implement hazard mitigation activities, including the following: planning and regulatory capabilities,
administrative and technical capabilities, financial capabilities, and education and outreach capabilities.
Planning and Regulatory
Planning and regulatory capabilities are the plans, policies, codes, and ordinances that prevent and
reduce the impacts of hazards.

Financial
Financial capabilities are the resources to fund mitigation actions. Talking about funding and financial
capabilities is important to determine what kinds of projects are feasible given their cost. Mitigation
actions, such as outreach programs have lower costs and often use staff time and existing budgets. Other
actions, such as earthquake retrofits, could require substantial funding from local, state, and federal
partners. Partnerships, including those willing to donate land, supplies, cash, or in -kind matches, can be
included.

Chapter 5: Mitigation Strategy
(In compliance with 201.6(c)(3)(i), 201.6(c)(3)(i), 201.6(c)(3)(ii), 201.6(c)(3)(iv), 201.6(c)(3)(iii), and
201.6(c)(4)(ii))
The mitigation strategy serves as the long-term blueprint for reducing the potential losses identified in the
risk assessment. The Stafford Act directs local mitigation plans to describe hazard mitigation actions and
establish a strategy to implement those actions.' Therefore, all other requirements for a local mitigation
plan (or hazard mitigation action plan) lead to and support the mitigation strategy.
Mitigation Goals
The Tarrant County HMPT collectively reviewed the extensive list of mitigation goals of the 2020 HazMAP
and unanimously chose to streamline the mitigation goals for this update. Therefore, the new goals are to
protect life and reduce bodily harm from natural hazards, and to lessen the impacts of natural hazards on
property and the community through hazard mitigation.
2020 Action Items
The City of Grapevine's action items in the 2020 Tarrant County HazMAP were determined by the 2020
LPT. Table 26 lists the action items from the 2020 plan and the status of each action.

New Mitigation Action Items
The City of Grapevine's action items were determined by the LPT for the 2025 HazMAP. These include
mitigation actions that qualify for mitigation funding and enforcement, maintenance, and response actions
that the City has identified as opportunities to increase its resilience to hazards.
During the capabilities assessment and hazard analysis, previously impacted assets and populations
were analyzed to determine the highest probability of damage and potential loss of life per hazard. As $1

TARRANT COUNTY HAZARD MITIGATION ACTION PLAN
spent in mitigation saves a community an average of $6 in recovery the LPT used these data to develop
a cost —benefit analysis: Estimated Cost x 6 = Estimated Benefit.
Priority will be assigned to projects with the greatest positive impact on community resilience, including
life safety and property protection. Table 27 lists the action items for this HazMAP.

TARRANT COUNTY HAZARD MITIGATION ACTION PLAN
Incorporating the Plan into Existing Planning Mechanisms
Based on Requirement 201.6(c)(4(ii) and the State of Texas Mitigation Plan, the vulnerability and
capabilities assessments for the City were carefully reviewed and considered when developing the
mitigation actions for this plan. The LPT will establish a process in which the mitigation strategy, goals,
objectives, and actions outlined in this plan will be incorporated into the existing local planning strategies.
Once the plan is adopted, the LPT will coordinate implementation with the responsible parties in the city
and external stakeholders as needed.
Steps for Implementing This HazMAP into Local Plans
• Change is proposed by an elected official or other interested party.
• The proposal is placed on the local agenda of the governing body.
• The agenda is published at least 10 days in advance of the meeting at which it will be discussed, so
members of the public have an opportunity to attend the discussion meeting. Publication may be
made by posting the agenda on the City's website, in the City newsletter, or on a public bulletin
board.
• The proposal is discussed at the public meeting, including any comments by members of the public
attendance.
• The proposal is voted on by the governing body.
• If the proposal is passed, the change is implemented by the appropriate local authority.
Integration into Local Planning Mechanisms
Incorporating the underlying principles of the HazMAP and its recommendations into other plans is a
highly effective and low-cost way to expand their influence. 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 the day-to-day functions and priorities of government and
public service. This plan builds on the momentum developed through previous and related planning
efforts and mitigation programs, and it recommends implementing actions, where possible, through these
other program mechanisms. These existing mechanisms include:
• Regularity Capabilities
• Administrative Capabilities
• Fiscal Capabilities
The respective planning authorities will conduct implementation and incorporation into existing planning
mechanisms through the routine actions of:
• Monitoring other planning/program agendas;
• Attending other planning/program meetings;
40 City of Grapevine
TARRANT COUNTY HAZARD MITIGATION ACTION PLAN
• 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. Regular efforts should be made to monitor the progress of mitigation actions
implemented through other planning mechanisms. Where appropriate, priority actions should be
incorporated into HazMAP updates. Existing planning mechanisms in which the HazMAP will be
integrated are listed in Table 28.
Table 28: Types of Plans That the City of Grapevine Can Use for Mitigation Actions
Capital Improvement Finance Department, Parks
Project Plans and Recreation Department
Drainage Master Plan Public Works Department
Addition of projects into capital
improvement budget.
City leadership and public works staff will
review identified mitigation action items
and consider plan revision as necessary to
address them.
Although there are many possible benefits to integrating components of this HazMAP into other planning
mechanisms, the LPT considers this HazMAP, including development and maintenance, to be the
primary vehicle to ensure the implementation of local hazard mitigation actions. 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.
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 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 using the City website or any other publicly accessible social platform (e.g.,
local newspaper, Facebook, Twitter) well in advance of any public meetings or comment periods.

TARRANT COUNTY HAZARD MITIGATION ACTION PLAN
PUBLIC INVOLVEMENT IN FIVE-YEAR UPDATES
When the LPT reconvenes for the five-year update, it will coordinate with all stakeholders participating in
the planning process —including those who joined the committee since the planning process began —to
update and revise the plan. In reconvening, the LPT 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.
