HomeMy WebLinkAboutItem 07 - Hazard Mitigation PlanMEMO TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM: BRUNO RUMBELOW, CITY MANAGER
MEETING DATE: JANUARY 7, 2020
SUBJECT: APPROVAL OF THE TARRANT COUNTY HAZARD MITIGATION
ACTION PLAN
RECOMMENDATION: Consider approval of a resolution adopting the Tarrant County
Hazard Mitigation Action Plan.
FUNDING SOURCE:
BACKGROUND: Starting in 2017, an update of the Tarrant County Hazard
Mitigation Action Plan (HMAP) was initiated by the North Central
Texas Council of Governments (NCTCOG) on behalf of Tarrant
County and 33 participating entities, including the City of
Grapevine. The plan has been conditionally approved by the
Federal Emergency Management Agency (FEMA) and to finalize
the planning process, each participating entity's governing body
must adopt the newly updated plan.
The 2020 plan builds upon the 2015 Tarrant County Local
Mitigation Action Plan, adopted through Grapevine City Council
resolution 2015-038, and the 2009 Tarrant County Mid -Cities
Local Mitigation Strategy, adopted through Resolution No. 2009-
02. This plan ensures Tarrant County and participating entities
comply with the Disaster Mitigation Act of 2000 and its
implementing regulations, 44 CFR Part 201.6, which maintains
eligibility to apply for federal technical assistance and post -
disaster hazard mitigation project funding. The update also
prioritizes potential risks and vulnerabilities in an effort to minimize
the effects of disasters in the participating communities.
The participating cities/entities include:
City of Arlington
City of Azle
City of Bedford
City of Blue Mound
City of Colleyville
City of Crowley
City of Dalworthington Gardens

Tarrant County Hazard Mitigation Action Plan
Chapter 2: Planning Process
(in compliance with 201.6(c)(1)J
2.1 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 Federal Code of
Regulations 44 CRF Part 201.6. While the City of Grapevine has historically implemented measures to
reduce vulnerability to some hazards, passage of DMA 2000 helped city officials recognize the benefits of
a long-term approach to hazard mitigation. This approach is achieved by a gradual decrease of hazard -
associated impacts through the implementation of 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) members, all participating Local Planning Team (LPT) members, the public, and
stakeholders.
The city developed this annex in accordance with Part 201.6(c)(5) of DMA 2000. This HazMAP and annex
identifies hazards and mechanisms to minimize damages associated with these hazards.
2.2 Organizing the Planning Effort
A comprehensive approach was taken in developing the HazMAP. An open involvement process was
established for the public and all stakeholders, which provided an opportunity for everyone to be involved
in the planning process and make their views known. 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 Local Planning Team (LPT).
Local Planning Team (LPT): Each jurisdiction had a LPT that consisted of the Emergency
Management Coordinator for that jurisdiction as well as designated representatives from
within the jurisdiction. This team met to assess capabilities, hazards, and mitigation strategies
within the jurisdiction.
2.2.1 Local Planning Team (LPT)
This annex within the Tarrant County HazMAP was developed by the City of Grapevine's Local Planning
Team (LPT), with support from the North Central Texas Council of Governments (NCTCOG). The efforts of
the LPT were led by the city's Emergency Management Coordinator.
The LPT was assembled in 2017 with representatives from the City of Grapevine. The city acted as the plan
development consultant, providing hazard mitigation planning services.

In addition, NCTCOG's Emergency Preparedness Department participated in the following activities
associated with development, approval, and adoption of the plan:
1. Prepared, based on community input and LPT direction, the first draft of the plan and
provided technical writing assistance for review, editing, and formatting.
2. Submitted proposed plan to the Texas Division of Emergency Management (TDEM) and the
Federal Emergency Management Agency (FEMA) for review and approval and completed
any edits requested by these organizations.
3. Coordinated plan adoption processes with the city, TDEM, and FEMA.

201.6(c)(2)(iii), and 201.6(c)(3)(ii))
The following information serves to assist the city in determining and prioritizing appropriate mitigation
action items to reduce losses from identified hazards.
).1 Changes in Development since 2015
(In compliance with 201.6(d)(3))
New development in hazard -prone areas:
There is continued infill development of mixed-use/high population density construction that will
increase overall vulnerability to natural hazards.
Mitigation actions implemented to reduce risk or adopted codes to protect future development:
There are ongoing capital improvements and newer, stronger construction materials that will decrease
vulnerability to natural hazards. A full list of completed mitigation action items are described in Chapter
5 of this annex.

Vulnerabilities
All populations, economy, structures, improved
property, critical facilities and infrastructure, and
natural environments are exposed to this hazard.
Drought conditions could increase the likelihood
of shifting soils underneath roads, homes, and
buildings resulting in greater road maintenance
costs and more shifting of foundations.
Additionally, ongoing drought could alter future
development planning due to water shortages.
Jurisdiction's ground -water supply: Grapevine residents receive approximately 70% of their drinking
water from the Trinity River Authority, which is supplied by Cedar Creek Reservoir and Richland Chambers
Reservoir. Approximately 30% of Grapevine's water comes from the city's water supply, Lake Grapevine.
Lake Grapevine's normal conservation pool elevation is 535 feet.
Any zoning districts which allow for agricultural uses such as commercial stables and barns, farms, and
animal lots, which could be impacted by drought: No.
Describe any water restrictions used in your jurisdiction: Irrigation or watering of any lawn or landscape
is prohibited between the hours of 10:00 am and 6:00 pm. The city's Drought Contingency Plan Ordinance
is outlined in Chapter 25, Article V, Section 25-140 of the Code of Ordinances.

blackouts due to extreme heat would adversely
impact the economy and critical facilities and
infrastructure.
Most vulnerable populations to extreme heat in your jurisdiction and their location within your
jurisdiction: The elderly, very young people, and people with poor health are most at risk from extreme
heat. People who work outside or in non -air-conditioned buildings are also at high risk to the direct effects
of extreme heat.
Are there cases of extreme heat exposure resulting from special events held in your jurisdiction?
Tourists, festival attendees, and park customers may have greater vulnerability to extreme heat due to
increased outdoor activities.
Have any critical facilities in your jurisdiction experienced any impacts from extreme heat (e.g., power
failure due to heat)? No.

facilities and infrastructure, and natural
environments around Grapevine Lake and
in/near floodplains are exposed to this hazard.
According to the City of Grapevine, there are six
public wastewater lift stations in the 100 -year
floodplain.
Past damage done to jurisdictional roads and critical infrastructure due to flooding, including where in
your jurisdiction the damage occurred: 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 damages and repair
costs. Dove Road was closed near Silvercrest Lane due to flooding. The Grapevine City Council estimated
rebuilding efforts would take months.

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 traffic. These crossings can be
dangerous when flooded. There are no low water crossings reported in the City of Grapevine.
National Flood Insurance Program Compliance
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 three basic components of the NFIP include: 1)
floodplain identification and mapping risk, 2) responsible floodplain management, and 3) flood insurance.
The City of Grapevine is a participant in the NFIP and provides details about the community and their
participation below. The following information was requested:

and the effects of wave action, if applicable, expected at the site.
• The necessity to the facility of a waterfront location, where applicable.
• The availability of alternative locations, not subject to flooding or erosion damage, for the
proposed use
What building restrictions, in regards to floodplains, does your jurisdiction enforce? General standards.
In all areas of special flood hazards the following provisions are required for all new construction and
substantial improvements.
• All new construction or substantial improvements shall be designed (or modified) and adequately
anchored to prevent flotation, collapse or lateral movement of the structure resulting from
hydrodynamic and hydrostatic loads, including the effects of buoyancy.
City of Grapevine Annex M-21
Tarrant County Hazard Mitigation Action Plan
• All new construction or substantial improvements shall be constructed by methods and practices
that minimize flood damage.
• All new construction or substantial improvements shall be constructed with materials resistant to
flood damage.
• All new construction or substantial improvements shall be constructed with electrical, heating,
ventilation, plumbing, and air conditioning equipment and other service facilities that are
designed and/or located so as to prevent water from entering or accumulating within the
components during conditions of flooding.
• All new and replacement water supply systems shall be designed to minimize or eliminate
infiltration of flood waters into the system.
• New and replacement sanitary sewage systems shall be designed to minimize or eliminate
infiltration of flood waters into the system and discharge from the systems into flood waters; and,
On-site waste disposal systems shall be located to avoid impairment to them or contamination
from them during flooding.
Specific standards. In all areas of special flood hazards where base flood elevation data has been
provided as set forth in (i) section 7-192, (ii) section 7-199(8), or (iii) section 7-202(c)(3), the following
provisions are required:
• Residential construction. New construction and substantial improvement of any residential
structure shall have the lowest floor (including basement), elevated to a minimum of two (2)
feet above the base flood elevation. All new residential construction shall have an access
elevation at or above the base flood elevation. No residential construction shall be permitted
in the floodway. A registered professional engineer, architect, or land surveyor shall submit a
certification to the Floodplain Administrator that the standard of this subsection as proposed
in section 7-200(a)(1), is satisfied.
• Nonresidential construction. New construction and substantial improvements of any
commercial, industrial or other nonresidential structure shall either have the lowest floor
(including basement) elevated to a minimum of two (2) feet above the base flood level or
together with attendant utility and sanitary facilities, be designed so that below two (2) feet
above the base flood level the structure is watertight with walls substantially impermeable to
the passage of water and with structural components having the capability of resisting
hydrostatic and hydrodynamic loads and effects of buoyancy. A registered professional
engineer or architect shall develop and/or review structural design, specifications, and plans
for the construction, and shall certify that the design and methods of construction are in
accordance with accepted standards of practice as outlined in this subsection. A record of
such certification which includes the specific elevation (in relation to mean sea level) to which
such structures are floodproofed shall be maintained by the floodplain administrator.

this hazard. Closures of roads and highways
would greatly impact the local, regional, and
statewide economy. Additionally, damages
suffered by power outages and broken water
lines would adversely impact businesses and
residents.
Bridges and overpasses that can be impacted by a winter storm, including street names and their
location within your jurisdiction: The bridges at Dove Road, Pool Road, Gaylord Texan Bridge, Ruth Wall
and Texan Trail, and Scribner at Northwest Highway. State highway flyovers and overpasses are managed
by the Texas Department of Transportation.
City of Grapevine Annex M-31
Tarrant County Hazard Mitigation Action Plan
What impacts are caused when these bridges and/or overpasses are impacted by winter storms? During
winter storms, frozen precipitation can accumulate on roadways causing vehicle crashes. Additionally,
freezing rain can build on power lines causing widespread power outages and frigid temperatures can
damage water pipes for homes and businesses.

How can any of these capabilities be expanded and improved to reduce risk?
Actions that can expand and improve existing authorities, plans, polices, and resources for mitigation
include: budgeting for mitigation actions; passing policies and procedures for mitigation actions;
adopting and implementing stricter mitigation regulations; approving mitigation updates, and additions
to existing plans as new needs are recognized.

Chapter S: 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 action
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.
5.1 Mitigation Goals
The Tarrant County Hazard Mitigation Planning Team (HMPT) collectively reviewed the extensive list of
mitigation goals of the 2015 Hazard Mitigation Action Plan (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.
5.2 2015 Action Items

5.3 New Action Items
The City of Grapevine's action items were determined by the Local Planning Team for the 2020 Hazard
Mitigation Action Plan (HazMAP). These actions include mitigation actions that qualify for mitigation
funding as well as enforcement, maintenance, and response actions that the city has identified as
opportunities to increase their resiliency 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 of loss of life per hazard. As $1
spent in mitigation saves a community an average of $6 in recovery2, we used this data to develop a cost -
benefit analysis: Estimated Cost x 6 = Estimated Benefit.
Priority will go towards projects with the highest positive impact on community resilience, including life
safety and property protection. Below are the action items for the 2020 HazMAP.

Tarrant County Hazard Mitigation Action Plan
5.4 Plan Incorporation into Existing Planning Mechanisms
Based on Requirement 201.6(c)(4(ii) and the State of Texas Mitigation Plan, the vulnerability and
capabilities assessment for the city were carefully reviewed and considered when developing the
mitigation actions for this plan. The Local Planning Team (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,
as well as external stakeholders as needed.
The following steps will be taken in implementing this HazMAP into local plans.
1. Change is proposed by an elected official or other interested party.
2. Proposal is placed on the local agenda of the governing body.
3. 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.
4. Proposal is discussed at the public meeting, including any comments by members of the public
attendance.
5. Proposal is voted on by the governing body.
6. If the proposal is passed, the change is implemented by the appropriate local authority.
Existing planning mechanisms in which the HazMAP will be integrated are listed below.

Although it is recognized that there are many possible benefits to integrating components of this Hazard
Mitigation Action Plan (HazMAP) into other planning mechanisms, the LPT considers this HazMAP,
including development and maintenance, to be the primary vehicle to ensure implementation of local
hazard mitigation actions.
