Chapter Two Planning Process
2.1 City of Cedar Hill
Planning Process The planning process for the City of Cedar Hill Hazard Mitigation Action Plan
(HazMap) was initiated by the development of Annex P "Hazard Mitigation" to the local
Emergency Operations Plan. Many players were involved in the planning process of Cedar Hill’s
Mitigation Plan. The members were selected for all functional areas that are applicable to this the
City of Cedar Hill. The HMT is responsible for coordinating and providing assistance with the
development, adoption, implementation, and maintenance of the mitigation action plan. The
process consisted of meetings to identify hazards, determine goals, and identify areas where
mitigation actions are needed. The following departments held representation on the Hazard
Mitigation Team (HMT) which was lead by the Emergency Management Coordinator (Hazard
Mitigation Coordinator).
Planning and Zoning Manager
Cedar Hill Mayor
Public Works Director
City of Cedar Hill Chamber of Commerce
Dallas American Red Cross Representative
Neighborhood Services/ Main Street Coordinator
Economic Development Director
Cedar Hill Purchasing Manager
City Engineer
City Attorney
Northwood University Representative
Cedar Hill Finance Director
Cedar Building Official
City Health Officer
Historical Preservation Representative
Public Involvement Open meetings were held giving the public opportunity to comment on the
Mitigation Action Plan. A public meeting was held May 8, 2007 at 6:00 pm in Cedar Hill Council
Chambers. Cedar Hill feels that public involvement is necessary for the effective development of
mitigation policy and procedures.
The business community, non-profits, academia, and neighboring communities were invited to
participate in the planning process through the public meeting announcements via the Dallas
Morning News.
A public meeting for community partners was held on June 5, 2007 at 1:00PM at the Dallas City
Hall. (See Attachment A) The public was informed, educated and involved in the mitigation
planning activities through the following methods: establishing a hazard mitigation team, posting
of public meetings and were given the opportunity to participate and comment on the Hazard
Mitigation Action Plan and its direction prior to its approval.
While an opportunity to the public was provided during the planning process, there was no
attendance from the Citizens, Non-Profits, Businesses, Academia, or Interested Parties.
Citizens, neighboring communities, local business, academia, agencies, nonprofits were also
invited to the Regional Emergency Preparedness Advisory Committee for an update on the
DaLMS and an opportunity to comment following the plan on November 11, 2008 (See
Attachment A)
2-2 Dallas County
Chapter Two
During November 12-14, 2008 an ad was posted in the Dallas Morning News (See Attachment A)
inviting the public, neighboring communities, local business, academia, agencies, nonprofits to
view and comment on the DaLMS on a website.
While these opportunities were provided there were no comments or input provided. An additional
opportunity for the public to comment on the plan will be held prior to formal plan adoption.
Plan Incorporation The Cedar Hill’s Fire and Building Codes are reviewed by the City Building
and Standards Commission. The fire code is enforced by the fire marshal. The fire marshal
reviews plans, makes inspections and investigates fires. Cedar Hill’s Building Code Effectiveness
Grading is 7.75 assigned to the City in June of 2002. The Fire and Building Codes were utilized
during the mitigation planning process as a reference to what Cedar Hill is currently doing to
mitigate the affects the identified natural hazards have on buildings. Through this process new
measures can be identified in the City’s codes which can be taken to mitigate loss of property and
life. The Fire and Building Codes also provided a foundation for Cedar Hill to assess natural
hazard vulnerability and identify potential mitigation efforts in action items.
In the early 1980’s the City of Cedar Hill adopted Floodplain Management Regulations as
required for inclusion in the National Flood Insurance Program. The initial Flood Insurance Study
that was conducted by FEMA was to improve current plan, completed on March 14, 1980 and
was adopted by the City in April of 1988. The NFIP data was used during the mitigation planning
process to assess flooding hazards and potential mitigation in the future.
The City's Comprehensive Zoning Plan is used in the mitigation planning process. The Planning
and Zoning Ordinance is enforced by city staff, Planning and Zoning Commission and City
Council. The City of Cedar Hill has existing mitigation activities that can be incorporated in to the
mitigation plan. The City of Cedar Hill Storm Drainage Master Plan was completed in February,
1999. Included in the scope of the Drainage Master Plan were Storm Water Runoff Calculations,
and Drainage Design Manual Recommendations. The Comprehensive Zoning Plan provided data
to direct the HMT in determining hazard mitigation goals and action items.
The City's Development Services Department is responsible for drainage improvement and flood
mitigation projects. In 1988 the City adopted floodplain management regulations as required for
inclusion in the National Flood Insurance Program. Current Floodplain Maps were adopted in
April of 1988. Section 7 of the City’s Code of Ordinance prohibits development in the floodway
and /or floodplain. The City Capital Improvement Project Plan is used to prioritize drainage
projects for inclusion in to the City's budget process. The Floodplain maps for Cedar Hill have
been incorporated into the mitigation risk assessment and are included in Chapter 3. These maps
assist the HMT in determining future mitigation needs in floodplains.
The Capital Improvement Plan is used to prioritize drainage projects for inclusion in to the City’s
budget process. Existing land use, ultimate land use and existing critical facilities within the
watershed will be evaluated. This plan includes provisions for ensuring that new facilities are built
to the most current codes, standards, and specifications; and avoid the extension of public
facilities in hazards areas. The Capital Improvement Plan is reviewed annually. Every year, staff
seeks input from citizens, boards and commissions, and homeowner’s associations for projects
that may be included in the Capital Improvement Plan. In concurrence with budget approval each
year, the City Council approves the Capital Improvement Program for a five year period. The
Capitol Improvement Plan provided direction to the HMT that the City Council and Cedar Hill
citizens have identified. The HMT used the Capitol Improvement Plan to develop projects which
would coincide with the future city efforts and projected growth.
The City of Cedar Hill was able to incorporate many of their existing plans in to the Hazard
Mitigation Action Plan. These plans were reviewed during the mitigation planning process and
used in the determination of hazards, goals, and action items.

2.2 City of Coppell
Planning Process This process has involved an in-depth review of planning and zoning and
engineering plans that would positively impact hazardous mitigation within our city. We then
reviewed our hazards and determined our threat from and the potential impact of them upon our
city.
The HMT will be an organization of flexible membership whose makeup and duties are
dependent upon the particular mitigation activity under consideration. This flexibility allows the
Hazard Mitigation Coordinator to tailor the group to meet the situation while ensuring the
involvement of appropriate individuals from the community.
The core group of the city of Coppell’s Hazard Mitigation Team comprises of the following city
officials.
Chief Building Official
Director of Engineering
Emergency Management
Fire Marshal
Director of Planning
Assistant Director of Public Works
Public Involvement The City of Coppell participated in the Dallas County Local Mitigation
Strategy public meeting on June 5th, 2007 at 1:00 located at the Dallas City Hall. Coppell citizens,
neighboring communities, businesses, agencies, academia, and non-profits as well as other
interested parties were invited by the newspaper posting in the Dallas Morning News. (See
Attachment A)
While an opportunity to the public was provided during the planning process, there was no
attendance from the Citizens, Non-Profits, Businesses, Academia, or Interested Parties.
Citizens, neighboring communities, local business, academia, agencies, nonprofits were also
invited to the Regional Emergency Preparedness Advisory Committee for an update on the
DaLMS and an opportunity to comment following the plan on November 11, 2008 (See
Attachment A)
During November 12-14, 2008 an ad was posted in the Dallas Morning News (See Attachment A)
inviting the public, neighboring communities, local business, academia, agencies, nonprofits to
view and comment on the DaLMS on a website.
While these opportunities were provided there were no comments or input provided. An additional
opportunity for the public to comment on the plan will be held prior to formal plan adoption.
Plan Incorporation Existing plans and studies that would impact pre-existing hazard mitigation
efforts were reviewed by the Engineering Department to determine if they would negatively
impact our hazard mitigation efforts. These plans included Building and Fire Codes, Capitol
Improvement Plan, and Zoning Ordinances. These plans were utilized to determine mitigation
objectives and to provide a collaborative approach in developing Action Items to address hazard
vulnerabilities.
The city of Coppell Engineering Department has done due diligence in the hazard mitigation for
the city to the point that very few buildings, infrastructure and critical facilities are within a
geographically defined hazard area. The city does not allow new development in the floodplain;
however, any structures that existed prior to Coppell being initially mapped (pre-FIRM) could be
2-4 Dallas County
Chapter Two
in the floodplain. The city engineer, as floodplain administrator, completes a biannual report to
FEMA concerning floodplain development. Currently there are 10 structures in a designated
floodplain. Those structures are all pre-FIRM.
The Engineering Department will ensure all plans, particularly Capitol Improvement Plans will
continue to incorporate the city’s proactive approach to mitigating hazards before they become
hazards by ensuring all projects meet or exceeds existing requirements of the city and the
HAZMAP.

Caleb Bartley and Jerry Martin took the lead in drafting the City of Dallas Hazard Mitigation Action
Plan 2007. The Hazard Mitigation Team provided frequent, substantive input throughout the
planning process. They shared technical expertise and planning suggestions along with providing
invaluable support in developing the list of action items and projects included herein.
Other departments, such as Dallas Fire-Rescue and Equipment and Building Services, have
duties which are affected by how well those mitigation efforts are implemented. The Public
Information Office offered assistance not only in drafting the Plan but also in facilitating its release
to the public. Lead by the Office of Emergency Management, this group participated in the
planning process of the City of Dallas Hazard Mitigation Action Plan.
Public Involvement Citizens of the City of Dallas and neighboring communities were invited to
participate in the planning process and to comment on the draft plan. The public meeting was
publicized through the Dallas Morning News and held on June 5th, 2007 1:00 pm at the Dallas
City Hall. (See Attachment A)
Businesses, agencies, academia, and non-profits as well as other interested parties are regularly

While an opportunity to the public was provided during the planning process, there was no
attendance from the Citizens, Non-Profits, Businesses, Academia, or Interested Parties
Citizens, neighboring communities, local business, academia, agencies, nonprofits were also
invited to the Regional Emergency Preparedness Advisory Committee for an update on the
DaLMS and an opportunity to comment following the plan on November 11, 2008 (See
Attachment A)
During November 12-14, 2008 an ad was posted in the Dallas Morning News (See Attachment A)

Plan Incorporation Dallas has many programs in place to address pertinent hazards ranging
from informing citizens about protective measures, warning the public of impending threats,
requiring safety measures to be incorporated in new buildings, acquiring and clearing properties
in high hazard areas and constructing flood control projects. Other mitigation measures exist in
the form of planning and guidance issued not only to assist in the City’s response efforts, but also
to direct the citizenry in new construction and renovations best practices from previous disasters.
The Dallas Master Emergency Operations Plan (MEOP) is one such plan and contains a hazard
analysis summary for several potential natural and man-made disasters. The MEOP guides the
City’s preparedness and response to an emergency or disaster. The Plan is reviewed each year
and it is certified by the City Manager every five years. In addition to this Plan, the City also
maintains robust building codes that aid in the mitigation of certain common hazards, such as
flooding. The MEOP was incorporated during the planning process to assist the HMT in
identifying their Vulnerability, Occurrence, and Impact of the Natural hazards.
The Capital Improvement Plan and the City Zoning Plans were heavily referenced in developing
this Hazard Mitigation Action Plan. These critical documents play an important and evolving role
in the development of the City of Dallas as well as of the emergency response plans that help
ensure the public’s safety. The Capitol Improvement Plan is especially incorporated in Chapter 4
as the city takes a comprehensive effort into implementing mitigation projects by identifying
projects within the Capitol Improvement Plan that satisfy the goals.
The current Hazard Mitigation Action Plan will build off of, support, and when necessary, guide
these pre-existing hazard mitigation efforts. This is done in order to ensure that mitigation is a
coordinated effort across the City’s departments and resources.

Public Involvement The City of Duncanville has developed a local hazard mitigation plan. A
Hazard Mitigation Team comprised of representatives from local government, community groups
and businesses with are located in Duncanville.
In order to involve the public in the planning process of the Local Hazard Mitigation Action Plan,
the City of Duncanville held a Public Hearing on March 6, 2007 in Duncanville City Council
Chambers at 7:00 PM. The public was provided another opportunity to comment on the plan
during the drafting stage, held on June 5, 2007, Dallas County Local Mitigation Strategy
conducted a meeting at Dallas City Hall at 1:00PM to discuss the plan during the drafting stage.
This public meeting was publicized through the Dallas Morning News.
Neighboring communities, agencies, businesses, academia, nonprofits, and other interested
parties were encouraged to attend both meetings and provide comments. Feedback received for
the public proved valuable to the development of the plan.

Duncanville residents and business will have an opportunity to comment on the plan during the
drafting stage and prior to the plan approval during public meetings. Public meetings will be held
after a first draft is produced and after a final draft is produced. A public hearing before adoption
of the mitigation plan will be conducted for any final public input.
In order to involve neighboring communities and local business, non-profits, businesses, and
other interested parties in the planning process the City of Duncanville held a Public Hearing on
March 6, 2007 for the Hazard Mitigation Action Plan during the planning process. Feedback
received for the public proved valuable to the development of the plan.
While an opportunity to the public was provided during the planning process, there was no
attendance from the Citizens, Non-Profits, Businesses, Academia, or Interested Parties.
Additional opportunities were provided to the Citizens, neighboring communities, local business,
academia, agencies, nonprofits were also invited to the Regional Emergency Preparedness
Advisory Committee for an update on the DaLMS and an opportunity to comment following the
plan on November 11, 2008 (See Attachment A)
During November 12-14, 2008 an ad was posted in the Dallas Morning News (See Attachment A)
inviting the public, neighboring communities, local business, academia, agencies, nonprofits to
view and comment on the DaLMS on a website.
While these opportunities were provided there were no comments or input provided. An additional
opportunity for the public to comment on the plan will be held prior to formal plan adoption.
Plan Incorporation During the planning process the City of Duncanville identified several plans
which were used to assist the HMT in assessing the risk and establishing potential mitigation
action items. Building Codes and Zoning Ordinances were utilized to establish the current
mitigation standards on new and existing structures. The Bentle Branch Storm Water and Stream
Stabilization Study provided the research data concerning the mapped floodplain and channel
stability. A 100 year floodplain along all tributaries to the Ten Mile Creek in conjunction with the
Capitol Improvement plan, which prioritize funding, mitigation goals and projects were assessed
and included in the DaLMS.

2.7 Farmers Branch
Planning Process The City’s Emergency Management Coordinator decided the City of Farmers
Branch should participate in the NCTCOG’s Multi-jurisdictional Hazard Mitigation Action Plan.
This decision was made to take advantage of the resources offered by the NCTOG to assist the
community in developing a functional plan that could obtain the appropriate approvals.
The City Engineer was appointed at the Hazard Mitigation Coordinator. The HazMAP Coordinator
worked with the City’s Emergency Coordinator to establish committee members. The committee
members are as follows:
Hazard Mitigation Coordinator City Engineer/ Farmers Branch
Public Awareness / Education Communications Director/ Farmers Branch
Emergency Preparedness and Response Fire Chief/ Farmers Branch
Disaster Recovery Director of Community Services/ Farmers Branch
Floodplain Management City Engineer/ Farmers Branch

Building Codes and Permits Building Official/ Farmers Branch
Environmental Protection Director of Community Services/ Farmers Branch
Property Condemnation Building Official/ Farmers Branch
Parks and Wildlife Director of Parks and Recreation/ Farmers Branch
Levee Management Valwood Improvement Authority Manager
Drainage Director of Public Works/ Farmers Branch
The HMT was established and procedures were developed to complete a HazMAP Risk
Assessment. The procedures were developed during the HMT orientation meeting. The purpose
for the Hazard Mitigation Plan was identified and the responsibility of each member was
explained. The recommended procedures were discussed. Comments from the meeting were
incorporated into the draft plan as appropriate.
The HMT also contacted organizations such as the Metrocrest Hospital Authority, Carrollton-
Farmers Branch Independent School District and public utility companies for input.
Representatives from volunteer agencies such as the American Red Cross had opportunities to
attend the Regional meetings regarding Mitigation Action Planning.
An additional opportunity for the public to comment on the plan will be held prior to formal plan
approval.
Public Involvement The committee planned a public meeting and advertised by including
information about the meeting in an advertisement in the Dallas Morning News, the City’s Branch
Mail e-mail connection system, the City’s web site, and on the City’s cable access channel. The
meeting was held in the Council Chambers of City Hall on June 8, 2004 at 6:00 PM. The
committee chairman presented a power point presentation explained the issues related to the
plan and the reason for the public meeting. Following the presentation, those in attendance were
given an opportunity to provide any input they desired.
All communities, local businesses, non-profit businesses, academia and other interested parties
were allowed to participate in the public meeting. Other selected organizations were contacted by
the committee to determine if they had input the committee needed.
While an opportunity to the public was provided during the planning process, there was no
attendance from the Citizens, Non-Profits, Businesses, Academia, or Interested Parties.

Plan Incorporation The committee discussed and reviewed appropriate local studies, plans,
reports and technical information. Additionally, these documents are to be reviewed at the time of
future assessments of the Hazard Mitigation Plan and included, where applicable, with future
funding reviews. Some of the current and past mitigation activities are as follows:
• Adopted Ordinance No. 1670 in 1987 to regulate activities within the 100-year floodplain.
• Rawhide Creek hydrologic and hydraulic study to update National Flood Insurance
Program model to regulate activities along the creek and to identify residents that need
to obtain flood insurance or no longer need flood insurance (2004)
• Development of City of Farmers Branch Flood Plane Development Plan
• Valwood Improvement Authority sump study to assess the amount of additional sump
storage that is needed to maintain 100-year flood protection within the area protected by
the Valwood Improvement Authority levees.
• Adopted the 2003 International Code series.
• Develops a Capital Improvement Plan for each annual budget for the City.
By reviewing the current planning mechanisms which concern mitigation effort the HMT was able
to incorporate their data into the risk assessment and future mitigation projects.

2.8 City of Irving
Planning Process The purpose of our Mitigation Action Plan (MAP) is to outline the nature and
extent of vulnerability and risk from natural hazards and man-made hazards potentially affecting
the City of Irving. It describes the actions required to minimize and/or eliminate the effects of
those hazards on our City.
The Public Works Director was designated as the Hazard Mitigation Coordinator (HMC). The
Emergency Management Coordinator (EMC) worked with the HMC in order to develop the
framework and create an outline of Irving's Hazard Analysis.
Through multi-departmental, jurisdictional and sector involvement, Irving's Emergency
Management staff facilitated discussions and information sharing necessary for a comprehensive
Hazard Analysis update.
Upon completion of the Hazard Analysis, multiple meetings were held involving the essential
departments, neighboring jurisdictions, volunteer agencies, and state and regional
representatives, in order to develop a coordinated approach to Mitigation Action Planning. Some
meetings were open to the public. After carefully considering input and discussions that occurred
in the public meetings, essential information was gathered and used to develop Irving goals,
objectives, and actions regarding mitigation planning. It should be noted that multiple objectives
and mitigation action items were developed with a high level of sensitivity to hazards seen as
major threats to the City of Irving (per Irving's Hazard Analysis).
Many professionals were involved in the planning process of Irving's Mitigation Action plan
(MAP). Including, but not limited to, multiple Irving departments and offices (City Management
staff, Irving Convention and Visitors Bureau, Planning and Development, Urban Development,
Public Works, Engineering and Construction, Streets and Drainage, Water/Wastewater
Operations and Maintenance, Environmental Compliance, Public Health and Environmental
Services, Solid Waste Collection and Disposal, General Services, Building Maintenance,
Warehouse and Print Shop, Information Technology, Communications, GIS, Finance, Police,
Fire, Emergency Management, Community Affairs, Parks and Recreation), neighboring and other
jurisdictions with important roles in developing Irving MAP, the North Central Texas Council of
Governments, State of Texas DEM, American Red Cross, and citizens of Irving.
Public Involvement Open meetings were held giving the public opportunity to participate and
comment on the Dallas County Local Mitigation Strategy and its direction during the planning
process. One such meeting involved regional players and was held locally at Irving’s Civic
Center. Additionally, hazard mitigation action planning was included in a Planning and Zoning
Commission public hearing on February 19, 2007 in the City Council Chambers at Irving City Hall.
At this hearing staff was available to answer any questions raised and address any comments
made. In the work session prior, a presentation regarding HazMap was given to planning and
zoning commission members to raise awareness and educate commission members on hazard
mitigation action planning within the Irving community. Informational pamphlets, brochures, and
DVDs were given out during a number of public outreach opportunities and these informational
materials include Irving Office of Emergency Management contact information allowing further
opportunities for comments. Irving OEM feels that public involvement is necessary for the
effective development of mitigation policy and procedure.
Regional meetings were held regarding Mitigation Action Planning and were highly attended by
neighboring jurisdictions in the North Central Texas Region. This allowed all jurisdictions to bring
ideas and concerns from businesses in their own area together. Representatives from volunteer
agencies, including the American Red Cross, had opportunities to attend the open meetings held
regarding mitigation planning. Irving Emergency Management staff members have numerous
professional affiliations which directly increases the incoming of new or best practice mitigation

ideas through email listings and info dissemination, meetings, seminar opportunities, and further
training opportunities.
The residents of Irving were also invited through the Dallas Morning News to a meeting held on
June 5th, 2007 1:00 pm at the Dallas City Hall.
Neighboring communities and local business, non-profits, businesses, and other interested
parties in the planning process the City of Irving were also invited through the Dallas Morning
News to the June 5th public meeting at Dallas City Hall.
While an opportunity to the public was provided during the planning process, there was no
attendance from the Citizens, Non-Profits, Businesses, Academia, or Interested Parties.
Citizens, neighboring communities, local business, academia, agencies, nonprofits were also
invited to the Regional Emergency Preparedness Advisory Committee for an update on the

While these opportunities were provided there were no comments or input provided. An additional
opportunity for the public to comment on the plan will be held prior to formal plan adoption.
Plan Incorporation The City of Irving maintains a comprehensive and coordinated approach to
all of its planning and strategy development. During the mitigation planning process this approach
was continued. Building codes, ordinances, emergency operations plan, the Irving Hazard
Vulnerability Assessment, and the Capital Improvement Plan were all used during the Irving MAP
planning process. Each of these plans provides direction for the City of Irving and allowed
mitigation planners to assess what the City’s needs were. By utilizing these plans in the planning
process, planners were able to create mitigation goals and develop mitigating action items for
consideration which would align with other city planning mechanisms.

2.9 Lancaster
Planning Process The planning process for the City of Lancaster's Hazard Mitigation Action
Plan began with the development of Annex P (Hazard Mitigation) to the Emergency Operations
Plan. Lancaster participated in public meetings at North Central Texas Council of Governments
concerning the process of developing a Regional Hazard Mitigation Action Plan. The City of
Lancaster joined the Regional Plan and developed a Hazard Mitigation Team. The HMT
prioritized mitigation and preparedness needs based on the Lancaster levels of vulnerability and
risk. The Emergency Management Coordinator for the City of Lancaster is responsible for the
development of Annex P (Hazard Mitigation) and the planning process for the Hazard Mitigation
Action Plan. The Emergency Management Coordinator has been designated as the Hazard
Mitigation Coordinator (HMC) and serves as the single manager/coordinator for this function for
the City of Lancaster. Hazard Mitigation Team consists primarily of representatives of local
government, but also includes partners that represent industry and the private sector.

Plan Incorporation Lancaster has several plans in place that address current mitigation
activities. During the planning stage the Hazard Mitigation Team will review protective mitigation
measures that can be incorporated in to the Hazard Mitigation Action Plan. Lancaster Fire and
Building Codes are reviewed by the City Building and Standards Commission. These codes and
standards assist with mitigation activities. In 1984 the City adopted floodplain management
regulations as required for inclusion in the National Flood Insurance Program. The
Comprehensive Zoning Plan and Capital Improvement Plan were important in developing the
Hazard Mitigation Action Plan. The Zoning Plan assisted with identifying subdivision, properties
and citizens that maybe in an hazardous area. The Capital Improvement Project Plan is used to
prioritize drainage projects for inclusion into the City's budget process. Each of these plans
assisted the Hazard Mitigation Team in its contribution to the DaLMS Goals and establishing
mitigation items.

2.10 Rowlett
Planning Process The purpose of our Mitigation Action Plan (MAP) is to identify the nature and
extent of vulnerability and risk from natural hazards and man-made hazards potentially affecting
the City of Rowlett. It describes the actions required to minimize and/or eliminate the effects of
those hazards on our City.
The Rowlett Hazard Mitigation Team consists of the Hazard Mitigation Coordinator (who is also
the Emergency Management Coordinator). Other members include City Management Office,
Public Works, Economic Development Director, Fire Chief, Public Information, Parks and
Recreation, Planning and Geographic Information System.
Through multi-departmental, jurisdictional and sector involvement, Rowlett's Emergency
Management office facilitated discussions and information sharing necessary for a
comprehensive Hazard Analysis update.
Upon completion of the Hazard Analysis, multiple meetings were held involving the essential
departments, volunteer agencies, and state and regional representatives, in order to develop a
coordinated approach to Mitigation Action Planning.
Meetings were open to the public to discuss the Hazard Analysis and Mitigation Plan. After
carefully considering input and discussions that occurred in all the meetings, essential information
was gathered and used to develop our goals, objectives, and actions regarding mitigation
planning.
Public Involvement Public meetings were held to allow for community involvement. In
accordance with city policy announcements were made and published for the meeting held on
October 13, 2005 at 7:00 pm at the Rowlett City Council Chambers.

2.11 City of Sachse
Planning Process The City of Sachse began the planning process by establishing a Hazard
Mitigation Team (HMT). The Hazard Mitigation Team consists of the City Manager and the
following City Department Directors:
Police Chief,
Fire Chief
City Secretary
Finance Director
Public Works Director
Community Development Director
Parks and Recreation Director
Library Director
Assistant Police Chief
Building Official
During the Hazard Mitigation Team meetings, a hazard vulnerability assessment was created in
order to establish goals and appropriate mitigation ac;tion items. The City of Sachse HMT
collaborated with the Dallas Local Mitigation Strategy (DaLMS) in adopting county-wide goals the
DaLMS believes that disasters do not stay within jurisdictional boundaries and a multi-
jurisdictional approach to mitigation will have the greatest impact for the citizens of Sachse and
Dallas County. The HMT used city plans, public involvement, and departmental goals during the
mitigation planning process to create the Sachse mitigation plan.
Public Involvement The City of Sachse held public awareness meetings and listed information
on the City’s website to inform the citizens. The City presented the Hazard Mitigation Action Plan
to the Public for comment on October 26, 2005. The public provided comments which were
implemented during the planning process.
Sachse residents, neighboring jurisdictions, interested parties, academia, and business were
invited through the Dallas Morning News to a public meeting on June 5th, 2007 1:00-3:00 pm at
Dallas City Hall for all jurisdictions participating in the Dallas County Local Mitigation Strategy and
NCTCOG Multi-Jurisdictional Regional Mitigation Strategy. While an opportunity to the public was
provided during the planning process, there was no attendance from the Citizens, Non-Profits,
Businesses, Academia, or Interested Parties.
Citizens, neighboring communities, local business, academia, agencies, nonprofits were also
invited to the Regional Emergency Preparedness Advisory Committee for an update on the

Chapter Three Hazard Analysis
3.1 Introduction to Hazard Analysis
The Hazard Mitigation Action Plan for Dallas County Local Mitigation Strategy is a tool to assist in
the identification and documentation of all the hazards faced in the region.
The Dallas County profile is one of many developed by the North Central Texas Council of
Governments under the FEMA Hazard Mitigation program. These plans are created by compiling
data from the NCTCOG regional natural hazards risk assessments, Damage Assessments,
Hazard Profiling and Identification as well as historical data and geographic information
Hazards Addressed Dallas County has identified the following Natural Hazards as having the
potential to cause damage in the county. Flooding, Stream Bank Erosion, Dam Failure, and
Levee Failure are the only hazards recognized to have predictable vulnerable areas. All other
hazards are equally likely to occur throughout the Dallas County jurisdictions.
Earthquake An earthquake is a sudden motion or trembling caused by an abrupt release of
accumulated strain on the tectonic plates that comprise the Earth's crust. The theory of plate
tectonics holds that the Earth's crust is broken into several major plates. These rigid, 50- to 60-
mile thick plates move slowly and continuously over the interior of the earth, meeting in some
areas and separating in others. As the tectonic plates move together they bump, slide, catch, and
hold. Eventually, faults along or near plate boundaries slip abruptly when the stress exceeds the
elastic limit of the rock, and an earthquake occurs. The ensuring seismic activity and ground
motion provoke secondary hazards: surface faulting, ground failure, and tsunamis. The vibration
or shaking of the ground during an earthquake is referred to as ground motion. In general, the
severity of ground motion increases with the amount of energy released and decreases with
distance from the causative fault or epicenter. When a fault ruptures, seismic waves are
propagated in all directions, causing the ground to vibrate at frequencies ranging from 0.1 to 30
Hz. Seismic waves are referred to as P waves, S waves, and surface waves.
Prior to October 2008 there was no historical evidence of an earthquake occurring in Dallas
County and geophysical field investigations at the Superconducting Super Collider (SCC) site in
Ellis County (South East of Dallas County) revealed no unusual rock foundation properties at the
site that would lead to anomalous ground motions during earthquakes. There are no known active
geological faults within Dallas County. Inactive normal faults of the Balcones fault system do
occur. During October 31 to November 1, 2008 there were seven earthquakes ranging from 2.5 to
3.0 on the Richter Scale in Dallas County. Due the recent event there is no research currently
available on these Earthquakes.
The most likely future risk is still associated to either a distant larger quake which might occur in
Missouri, Tennessee, or Oklahoma, though these earthquakes are probable to occur only once
every 500 years. The second likely occurrence for earthquakes is large amount of hydrocarbon
production occurring in the northwestern area of the North Central Texas region including Dallas
County. Natural Gas Extractions has been responsible for creating small earthquakes within the
formations which it is produced, in the case of the North Texas natural gas play, the primary
formation is the Barnett gas play. Due to the risk being associated to a distant quake,
Earthquakes affect the planning area equally.
Tornado A violently rotating column of air, in contact with the ground, either pendant from a
cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a
condensation funnel cloud. Tornados affect the entire planning area equally.
Hail Outgrowth of a severe thunderstorm in which balls or irregularly shaped lumps of ice greater
than 0.75 inches in diameter fall with rain. Early in the developmental stages of a hailstorm, ice
3-2 Dallas County
Chapter Three
crystals form within a low-pressure front due to warm air rising rapidly into the upper atmosphere
and the subsequent cooling of the air mass. Frozen droplets gradually accumulate on the ice
crystals until, having developed sufficient weight, they fall as precipitation. Hail affects the entire
planning area equally.
High Winds Wind is defined as the motion of air relative to the earth’s surface. The
horizontal component of the three-dimensional flow and the near-surface wind phenomenon are
the most significant aspects of the hazard. Straight-line winds are often responsible for most of
the wind damage associated with a thunderstorm. These winds are often confused with
tornadoes because of similar damage and wind speeds. However, the strong and gusty winds
associated with straight-line winds blow roughly in a straight line unlike the rotating winds of a
tornado. Downbursts or microbursts are examples of damaging straight-line winds. A downburst
is a small area of rapidly descending rain and rain-cooled air beneath a thunderstorm that
produces a violent, localized downdraft covering 2.5 miles or less. Wind speeds in some of the
stronger downbursts can reach 100 to 150 miles per hour, which is similar to that of a strong
tornado. The winds produced from a downburst often occur in one direction, and the worst
damage is usually on the forward side of the downburst. High Winds affect the entire planning
area equally
Lightning Thunderstorm and lightning events are generated by atmospheric
imbalance and turbulence due to the combination of the following conditions: unstable warm
air rising rapidly into the atmosphere; sufficient moisture to form clouds and rain; and upward
lift of air currents caused by colliding cold and warm weather fronts, sea breezes or
mountains. Lighting is generated by the buildup of charged ions in a thundercloud, and the
discharge of a lightning bolt interacts with the best conducting object or surface on the ground.
The air channel of a lightning strike reaches temperatures higher than 50, 000 degrees
Fahrenheit. The rapid heating and cooling of the air near the channel causes a shock wave,
which produces thunder. Lightning affects the entire planning area equally.
Winter Storms Winter storms originate as mid-latitude depressions or cyclonic weather systems,
sometimes following the path of the jet stream. A winter storm or blizzard, combines heavy
snowfall, high winds, extreme cold and ice storms. Many winter depressions give rise to
exceptionally heavy rain and widespread flooding and conditions worsen if the precipitation falls
in the form of snow. The winter storm season varies widely, depending on latitude, altitude and
proximity to moderating influences. Winter Storms affects the entire planning area equally.
Summer Heat Severe summer heat is characterized by a combination of a very high
temperatures and exceptionally humid conditions. When persisting over a period of time, it is
called a heat wave. Summer Heat affects the entire planning area equally.
Drought Drought can be defined as a water shortage caused by the natural reduction
in the amount of precipitation expected over an extended period of time, usually a season or
more in length. It can be aggravated by other factors such as high temperatures, high winds, and
low relative humidity. Drought affects the entire planning area equally.
Flooding Flooding is defined as the accumulation of water within a water body and
the overflow of excess water onto adjacent floodplain lands. The floodplain is the land adjoining
the channel of a river, stream, ocean, lake, or other watercourse or water body that is susceptible
to flooding. The statistical meaning of terms like “25-year storm” and “100-year flood” can be
confusing. Simply stated, a floodplain can be located anywhere; it just depends on how large and
how often a flood event occurs. Floodplains are those areas that are subject to inundation from
flooding. Floods and the floodplains associated with them are often described in terms of the
percent chance of a flood event happening in any given year. As a community management or
planning term, “floodplain” most often refers to an area that is subject to inundation by a flood that
has a one percent chance of occurring in any given year (commonly and incorrectly referred to as
the 100-year floodplain).

Regional Mitigation Strategy
Flooding is a natural hazard that has been identified as having a predictable vulnerable area. The
FEMA Q3 Flood zones (Maps E.1-E.11) depict a satellite view of the community in relation to the
100 and 500 year flood zones. The Landuse maps (J.1-J.11) depict the type of structures in the
community by Residential, Commercial, and Undeveloped. The Landuse maps also identify
Emergency Operation Centers, Fire Stations, Police Station and Hospitals. The FEMA Q3 Flood
zones are overlaid to demonstrate what facilities and types of facilities are at risk in each
community in the event of a flood.
The following is a further identification of Flooding in the participating jurisdictions:
Unincorporated Dallas County Over 90% of the land in Dallas County is located within a city.
Since, in Texas, usually only cities - and not counties - have the authority to adopt zoning and
building ordinances. Less than ten percent of the land in the County is not located in a city. Much
of this un-incorporated land is considered to be in the federally-designated floodplain. Rural
unincorporated Dallas County, which is located in the southeast portion of the county /o, consists
of single family dwellings, mobile home parks, and many preserve and sanctuaries such as: Fin
and Feather Club Lake, Trinity River Greenbelt, Dallas Hunting and Fishing Club Lake, Goat
Island Preserve, Cottonwood Creek Preserve, Palmetto/Alligator Slough Preserve, Simonds Lake
and Park, Post Oak Grove Preserve, Trinity River Greenbelt Preserve Riverbend Section, and
Audobon Bird Sanctuary.
Because the un-incorporated areas of Dallas County lie within a federally-designated floodplain,
the likelihood of the unincorporated areas of Dallas County to be flooded is very likely due to
number of aging and unmaintained levees that are located within the floodplain. Please see the
South East Dallas County Floodplain map that outlines the 100 and 500 year floodplains for the
unincorporated areas of Dallas County.
Approximately two years ago, in the unincorporated areas of Southeast Dallas County at 14300-
15000 Beckett Rd became flooded due to a levee breach which flooded gravel sloughs that
submerged commercial excavating equipment, a crane and damaged two or three homes in this
area. From April 2005 through 2007, Dallas County received a grant to relocate 100 residents in

City of Cedar Hill There are four major drainage basins within the City boundaries : Upper Red
Oak Creek, Upper Ten Mile Creek, Joe Pool Lake, and Chambers Watershed. Average
temperature is 66.10°F and the average annual rainfall is 33.7 inches. Currently, the City has
approximately 107 miles of storm sewers and 258 miles of roadway.
Because of significant growth and development within the past eight years, more impervious
surfaces have been added throughout Cedar Hill resulting in increased runoff and potential threat
of flooding. The City is subject to variable amounts of rainfall resulting in flooding for short
periods of time. Development within the Bentle Branch floodplain has resulted in the construction
of a regional detention facility to receive the storm water from the surge of growth experienced in
that area.
The City of Cedar Hill joined the Federal Emergency Management Program on July 21, 1974.
The City began the Flood Insurance Rate Mapping (FIRM) effort on April 1, 1981.
Criteria and standards have been established by the City of Cedar Hill to govern the use of
natural streams and floodplains and to serve as guidelines for the development of man-made
drainage facilities and the improvement of natural channels (Ordinance #94-194 on September
24, 1994). Floodplains in the City are managed by a flood damage prevention ordinance passed
by the City Council on April 5, 1088 (Ordinance #88-968). This ordinance designates the
floodplain administrator as a single point contact to oversee issues and record the studies and
records of floodplain areas established within the city.
On February 1999, the City implemented a Storm Drainage Master Plan. This plan provides
information regarding major drainage projects and analyzes the design manual for improvements.
Residential areas prone to flooding are west of Lake Ridge Elementary School, including parts of
Sunrise Court. Street flooding have been observed and described at the following locations:
1. Clark and 500 blk of Astoria – Just south of Astoria on Clark Road; water drains out into the
roadway.
2. 2900 blk of Lakeview Drive - Very high water during large rainfall events.
3. Duncanville Road - Just north of Ovilla city limits; water runs across roadway during large rain
fall events.
4. 1300 blk of Joe Wilson Road - Just north of Bear Creek under large rain events; water runs
across roadway.
5. 200 blk of Kenya Street - East of Clark Road. Water builds up in the roadway during large rain
events.
6. 100 blk of Joe Wilson Road - On the corner by the Tiger Mart, water builds up during heavy
rainfalls.
7. Wood Lane and Little Creek - Large amounts of water shed across the roadway of Wood
Lane. Roadway floods when private pond on the west side of Wood Lane becomes full.
8. West Wintergreen and High Pointe – This intersection floods under very large rain fall events.
9. Meadow Ridge Drive and Daniel Lane - This intersection floods during large rain fall events.
City of Coppell The City of Coppell contains three major tributaries that ultimately drain into the
Elm Fork of the Trinity River along the eastern City limits. Approximately 5.4 square miles of the
City is drained by Grapevine Creek, and approximately 7.9 square miles of the City is drained by
Denton Creek, including 2.8 square miles drained by Cottonwood Branch, a major tributary of
Denton Creek. The remaining 1.7 square miles drains directly into the Elm Fork of the Trinity
River. The Northwest Dallas County Flood Control District, the Denton County Levee
Improvement District No. 1, and the Irving Flood Control District are all located within the City
limits.

Regional Mitigation Strategy
Having experienced a significant history of flooding, the City of Coppell actively engages in
measures to reduce the impact of flooding on the community. The City's active mitigation efforts
include participation in National Flood Insurance Program, public education, floodplain
management and storm water management. Coppell promotes public education through the
posting of ordinances and information on the City’s website and in common areas. The City has
also enacted ordinances and guidance with roles in flood mitigation which include: Subdivision
Ordinance, Erosion and Sedimentation Control Ordinance, Comprehensive Zoning Ordinance,
Storm Drainage Design Criteria, Standard Construction Details Code and Floodplain
Management Ordinance.
City of Dallas The Elm Fork and main stem of the Trinity River run through the heart of Dallas.
The Dallas Floodway protects much of the city from flooding directly from the river, but the sumps
and pump stations on the interior of the levees do not have capacity for 100-year flood protection.
Significant flooding occurred on the interior sides of both the east and west levees on March 19,
2006. Hardest hit were the Hampton/Oaklawn Sump on the east, and both Pavaho and Trinity-
Portland Sumps on the west.
Significant flooding has also occurred on major streams such as White Rock Creek, Bachman
Branch, Turtle Creek, Joes Creek, and Elam Creek, as well as smaller streams such as Knights
and Cedar Springs Branches, Rush Creek, and Ricketts Branch. Loss of life as well as property
damage occurred on May 5, 1995. The Trinity River downstream of the Dallas Floodway
experienced three near-100-year events in the area of Cadillac Heights (west side) and
Rochester Park (east side) between 1989 and 1991.
No longer natural streams, Mill Creek and Peaks Branch were fully enclosed from the 1920’s
through the 1960’s. Various standards were used for design of the pipe and culvert systems,
leaving significant portions with less than 2-year capacity. During heavy rains, lack of system
capacity frequently results in water coursing down the streets and across city blocks, following the
trace of the old creeks. Significant flooding in these areas occurred in 1995 and twice in 2006.
Flooding problems in Dallas are addressed through capital bond programs. Dallas maintains a
needs inventory that serves as a project source for bond program development. Problems
identified and listed in the flood and drainage needs inventory come from floodplain management
study recommendations and staff investigations of reported flooding occurrences. In 2006, voters
approved a bond program that includes over $334M in funding for flood-related projects.
Ongoing work includes the first phase of deep tunnel relief systems for Mill Creek and Peaks
Branch, replacement of three pump stations in the Dallas Floodway system, and numerous other
flood- and drainage-related projects. Over $600M in flood and drainage needs remains unfunded.
City of DeSoto DeSoto is located in the Best Southwest portion of Dallas County. The City of
DeSoto is situated just minutes from downtown Dallas. Bordering I-35 on its eastern border and
Highway 67 on it northern boundary, the City covers approximately 21 square miles. Ten Mile
Creek, Spring Creek, Health Creek, Bee Branch and Stewart Branch are some of the major
streams that flow through the City. There are also several small tributaries that drain into these
creeks.
In the early 1980’s the City of DeSoto adopted Floodplain Management regulations as required
for inclusion in the National Flood Insurance Program. The initial Flood Insurance Study (FIS) that
was conducted by FEMA was completed on April 17, 1984. On August 23, 2008, FEMA issued a
new Flood Insurance Rate Map that updated DeSoto’s floodplain and floodway of Heath Creek
and Spring Creek.
Criteria and standards have been established by the City of DeSoto to govern the use of natural
streams and flood plains and to serve as guidelines for the development of man-made drainage
facilities and improvement of natural channels. DeSoto method of reducing flood losses is to
prevent or regulate the construction of flood barriers which will unnaturally divert flood waters or
which may increase flood hazards to other land. Floodplains in the City are controlled by a Flood
3-6 Dallas County
Chapter Three
Damage Prevention ordinance passed by the DeSoto City Council on March 16, 1987. The City
of DeSoto Drainage Master Plan and Drainage Design and Storm Water Pollution Prevention
Manual were adopted by ordinance September 2001. Included in the scope of Drainage Master
Plan was a hydraulic study of all tributaries to Ten Mile Creek. A 100-year flood level was
established through this study of all tributaries. This study insures that no structures will encroach
in stream areas as the City of DeSoto continues to develop.
Ten Mile Creek and tributaries have provided the community along its stream banks with a
pleasant amenity. The area surrounding Ten Mile Creek and Spring Creek is made up of made
up of primarily one major land use, residential areas. After the May 17, 1989 Ten Mile Creek
Flood, a Corps of Engineers project widened the Ten Mile Creek Channel at the Hampton Road
Bridge to reduce the likelihood of future flood damage.
In June of 2000 DeSoto experience moderate flooding long Ten Mile Creek. However some
resident have reported that Ten Mile Creek has come close to overtopping its banks in recent
years. Prior to the drainage improvement along Brookview Drive, the alley of Brookview Drive did
not have the capacity to carry and contain storm waters caused by heavy rains resulting in
flooding of homes. In DeSoto both sides of Woodhaven Drive and North side of Ten Mile Creek
Drive have experience flooding. Based on past flood history, approximately 39 housing units
would be at risk from flooding along Ten Mile Creek.
In the pass heave rains resulted in a localized flooding event in Wolf Creek subdivision. The
scope of this project consists of upsizing the existing storm drain pipes, building a dirt barrier
north of the Wolf Creek addition and constructing a detention pond just north of the Wolf Creek
subdivision.
The quality of life for the citizens of DeSoto depends in part upon adequate drainage facilities.
The City of DeSoto developed the Drainage Design and Strom Water Pollution Prevention
Manual. This Manual establishes criteria procedures and data for drainage evaluation to ensure
the adequacy of new drainage facilities. The intent is to minimize potential negative drainage
impacts caused by development. The City mitigation goals and long-term strategies are to reduce
the likelihood of structural flooding by eliminating development within the floodplain and provide
onsite detention of stormwater runoff. It is the policy of the City to limit development or fill in the
100-year floodplain shown on the Storm Drainage Master Plan.
The development of the remaining undeveloped land in DeSoto offers the opportunity to achieve,
through careful planning and guidance, the type of community and the quality of life the citizens of
DeSoto deserve.
City of Duncanville The Bentle Branch watershed drains approximately 3.65 square miles of
Dallas County from its headwaters near Beltline Road to its confluence with the Tenmile Creek.
According to local residents, historically severe flood events have not occurred along Bentle
Branch to cause significant flooding problems. However, residents have reported that the stream
has come close to overtopping its banks several times recent years. This trend of increased
flooding has been attributed to the development that has occurred within the basin in recent
years.
Severe flooding was experienced in the Bentle Branch basin. Localized flooding during July 2004
produced well above normal runoff and stream flows in most of southwest Dallas County. The
City of Cedar Hill reports a maximum rainfall total of over 12 inches during that period. The City of
Lancaster was hardest hit by the storm, receiving close to 13 inches in less than eight hours
according to the National Weather Service. As a result of theses heavy rains, Bentle Branch
overtopped its banks in some areas on Tenmile Creek. This flooding along with increasing
development along the floodplain upstream of Duncanville, led to the commission of the Stream
Stability and Storm Water Management Update. Homes that reported flooding from the July 2004
storm were 303 and 307 W. Cedar Creek Drive along Tenmile Creek at the confluence with
North Central Texas Council of Governments 3-7
Regional Mitigation Strategy
Bentle Branch. The hydraulic analyses from this study confirm that there are no structures
inundated by the 100-year flood on Bentle Branch with the exception of the structures located at
the confluence with Tenmile Creek.
The Flood Plain Information Report on Ten Mile Creek published in May 1986 indicated the
largest known flood on Ten Mile Creek occurred in May 1908. The second highest known flood
occurred in April 1942. The flood of June 1946 was the third largest known flood, and at least five
bridges in the upper and middle reaches of Ten Mile Creek were completely washed away. The
study involved portions of each of the following streams: Ten Mile Creek, Mauk Branch, Stewart
Branch, Horne Branch and Bentle Branch. The Bentle Branch watershed has become one of the
region’s most rapidly developing areas and is located within the Tenmile creek drainage basin.
The majority of the watershed is located in the City of Cedar Hill, upstream of Duncanville. The
mile long reach and watershed of Bentle Branch located in Duncanville is almost completely
developed by residential communities.
Development in and along the Bentle Branch floodplain increases these problems, the City of
Duncanville commissioned this Bentle Branch Stream Stability Study and Stormwater Master
Plan to address channel stability and drainage problems that might be caused by future floods.
This floodplain management study covers the reach of Bentle Branch from the city limits just
upstream of Joe Wilson Road downstream to Tenmile Creek. Changes in the watershed that
have affected flood discharges and erosion along the reach of Bentle Branch that flows through
the City of Duncanville are due in part to the development upstream in Cedar Hill. Much of this
development as occurred within the last ten years, but large tracts still development of such areas
is often accompanied by increased flood flows resulting from urbanization agricultural acreage to
residential, commercial, and industrial development already exist for Cedar Hill.
The City of Duncanville joined the Federal Emergency Management Program on April 15, 1981.
The original Flood Insurance Study (FIS) for the City of Duncanville was published in August
1979. A Flood Insurance (DFIRM) Remapping effort began for all of Dallas County in 2004 to
update all floodplain mapping. The remapping effort includes the Bentle Branch watershed in
Duncanville as part of the remapping effort.
In January 1986, a report entitled A Flood Control Feasibility Study of Tenmile Creek &
Tributaries For The City of Duncanville, Texas was published. This report included the reach of
Bentle Branch that flows through Duncanville. The 100 year frequency flood elevation and
discharges were developed based on a fully developed watershed and, channel improvements
were recommended.
Criteria and standards have been established by the City of Duncanville to govern the use of
natural streams and flood plains and to serve as guidelines for the development of man-made
drainage facilities and improvement of natural channels. Floodplains in the City of Duncanville are
controlled by a flood damage prevention ordinance passed by the Duncanville City Council on
March 16, 1987. The floodplains delineated in this report are subject to this ordinance. The City
also generally utilizes the City of Dallas’ Drainage Design Manual for all development plans.
Existing development which is subject to overbank flooding is primarily residential, but also
includes some commercial and light industrial property. An estimated 140 buildings are within the
limits of the 100-year flood plain, which covers about 402 acres. All of the 47 acres in the Bentle
Branch flood plain in Duncanville is privately owned. There is no City owned property within the
floodplain.
City of Farmers Branch The City of Farmers Branch has three creeks that run through the City
flowing towards the Elm Fork of the Trinity River. They are Cooks
Creek, Rawhide Creek and Farmers Branch Creek. These creeks are the
major drainage channels for the entire City and for some portions of neighboring cities. During
heavy rains, these creeks frequently rise rapidly. On occasion flood waters have flowed over low
3-8 Dallas County
Chapter Three
bridge crossing and entered some homes. This is has occurred along the Cooks Creek at Bee
Street, Rawhide Creek at Brookhaven Drive, and along Farmers Branch Creek between Marsh
Lane and Valley View Lane. The elevation of water has never been a life-safety issue at the
residences, but has resulted in inside water damage for approximately 10 homes. There have
been occurrences of vehicles being washed off the roads at the low water crossings on Marsh
Lane and Bee Street. There has been no occurrences of flooding near the Elm Fork of the Trinity
River at the City's western boarder since levees were constructed by the Valwood Improvement
Authority in the late 1970s.
City of Irving There are five drainage basins that cause the majority of flooding in Irving. The
Elm Fork of the Trinity River is our eastern border. There are no insurable structures in the Elm
Fork floodplain. The West Fork of the Trinity River is a major portion of our southern boundary.
There are over 300 insurable structures in the West Fork floodplain. Bear Creek is our third
largest watershed. There are over 100 insurable structures in the Bear Creek floodplain,
however, most of them are in the shared Bear Creek/West Fork floodplain and would have 6
inches to one foot more water inside the structure during a West Fork flood.
Delaware Creek has a 9.23 square mile watershed with approximately 100 insurable structures in
the floodplain. West Irving Creek has a 3.2 square mile watershed with approximately 160
insurable structures in the floodplain.
The last major flood in Irving was May 5, 1995 with approximately 100 structures being flooded.
The City has been making drainage improvements to our systems based on that event ever
since.
City of Lancaster Lancaster is a city of over 35, surrounded by open farmland, low rolling hills,
creeks and woodlands. It is evident that in recent years Lancaster has been competing with cities
like DeSoto Cedar Hill and Duncanville, among others, to capture a part of the region’s growth,
and this trend could realistically continue. Today, many portions of the City remain undeveloped,
and therefore, extensive additional development can be expected to occur in those areas. City of
Lancaster has a higher-than- average amount of commerical land use. Cedar Valley College,
Lancaster Municipal Airport and Dallas Logistics Hub are all located in the City of Lancaster.
The 2007 Environmental Assessment project site is located along Nokomis Road as it crosses
Tenmile Creek in Lancaster. The U.S. Army Corps of Engineers proposed project is required to
repair and prevent stream bank failure and protect Tenmile Creek bridge as well as Nokomis
Road from further erosion induced damages. The project is authorized under Section 14 of the
Flood Control Act of 1946, as amended. The City owns the bridge and it provides access to
homes, businesses, and schools with an estimated traffic count of 1,200 cars per day. Based on
the field investigation, erosion calculations, and visual inspections, if erosion is not stabilized, the
stream banks will continue to fail. At the current rate of erosion, both the embankment and the
bridge for Nokomis Road are likely to be negatively impacted within the next five years. Five
alternatives were considered during the plan formulation process for the stream bank protection.
These alternatives included: 1) gabions; 2) rock riprap; 3) a concrete slope structure; 4)
prepackaged concrete riprap bag slope protection, and 5) a “No Action” plan. Alternative 4 was
chosen as the recommended plan based on the plan’s cost effectiveness for providing protection
against further stream bank erosion at the problem site and the plan’s ability to protect the bridge
structure and road from erosion induced failure.
Tenmile Creek flows in an easterly direction through the south end of the City. There has been
significant erosion of the stream banks in the area where Nokomis Road and Tenmile Creek
intersect. The creek was ten miles longer and flowed into the Trinity in Ellis County before it was
diverted and channeled into the river at its present location. Where not diverted, the creek has a
limestone bottom. Today, the creek flows through the corporate limits of Cedar Hill, Duncanville,
De Soto, Lancaster, Wilmer, and Ferris. The findings of this Environmental Assessment indicate
that there is a need for stream bank protection near Nokomis Road and bridge at Tenmile Creek.
North Central Texas Council of Governments 3-9
Regional Mitigation Strategy
The prepackaged concrete riprap bag slope protection alternative would provide streambank
protection against further erosion and protect the affected public bridge and road.
Recently, flooding was experienced along Ten Mile Creek. Localized flooding during March 2008
produced well above normal runoff and streamflows in the City of Lancaster. Officials sent
voluntary evacuation notices to 687 registered CodeRed phone numbers and closed about 16
streets in reponse to flooding. Homes located on Enchanted Lane experience flooding because of
their proximity to Ten Mile Creek. Currently, some home along Enhancted Lane are now for sale.
In July 2004 the City of Lancaster was hardest hit by rain, receiving close to 13 inches in less that
eight hours according to the National Weather Service. Ten Mile and Bear creeks were forced out
of their banks, and more than 100 homes were flooded.
City of Lancaster joined the Federal Emergency Management Program on June 7, 1974. The
City began the Flood Insurance Rate Mapping (FIRM) effort September 1981. Stormwater
management policies are defined by stormwater management ordinance 2004-07-21, adopted on
July 26, 2004. The City’s policies for stormwater management govern the planning, design,
construction, operation, and maintenance of storm drainage facilities within the City’s jurisdiction.
This storm water management policy is based on the Lancaster Storm Water Management
Ordinance and Storm Water Design Manual. The City Parks, Recreation and Open Space Master
Plan was prepared in 1997. The purpose of this plan was to provide direction in the acquisition
and development of park land and open space needs. The Open Space Plan creates an open
space system to link parks, schools, greenbelts and open spaces in the City.
Criteria and standards have been established by the City to govern the use of natural streams
and flood plains and to serve as guidelines for the development of man-made drainage facilities
and improvement of natural channels. The drainage ways, creeks and flood hazard areas of the
City of Lancaster are subject to periodic inundation which may result in property, health and
safety hazards, disruption of commerce and governmental services and extraordinary public
expenditures for flood protection and relief, all of which adversely affect the public health, safety
and general welfare.
City of Rowlett Flooding has been identified as the primary natural disaster to be faced by the
City of Rowlett. Long Branch Creek, Rowlett Creek, and Muddy Creek, as its tributaries run
through the city. The city has taken some measures to reduce the incidents of flooding within the
city, which have been addressed in this document. Some additional areas continue to be
problematic though causing more road closures issues than danger to homes or business. Main
Street, Waterview Drive ,Liberty Grove Road, Dalrock, Schrade Road, Chiesa Road, Miller Road,
and Scenic Road bridge are often closed due to flooding. These roadway are main arterials that
would cause major problems if the city needed to evacuated because of a natural disaster.
Localized street flooding in residential areas is being addressed through our Capital Improvement
Program. New construction cannot be in the floodway and built in the flood plain and must flood
proofed two above BFE.
City of Sachse. Flooding has been identified as the primary natural disaster to be faced by the
City of Sachse. Rowlett Creek, Maxwell Creek, Long Branch of Muddy Creek, Willow Lake and
Muddy Creek as well as its tributaries run through the city. The city has taken some measures to
reduce the incidents of flooding within the city which have been addressed in this document.
Some additional areas continue to be problematic though causing more road closure issues than
danger to homes or businesses. Highway 78, Merritt Road and Sachse Road often require to be
closed due to flooding, though this limits many of our evacuation routes should other hazard
events occur. Floodways near homes are being addressed to alleviate storm water drainage
problems. New construction cannot be built in the floodway and those built in the flood plain must
be flood proofed two feet above BFE.
Stream Bank Erosion Stream channels are eroded by the energy of flowing water. The two
types of stream bank erosion are the surface erosion of channel bank material and mass wasting.
Surface erosion is the removal of individual soil particles due to the tractive force of water. Mass
3-10 Dallas County
Chapter Three
wasting is defined as a structural failure of a section of the stream bank, which can be caused by
undercutting due to surface erosion.
Stream bank erosion occurs when development of the contributing watershed results in increased
impervious area, reduced infiltration, increased runoff, and increased flood frequencies. These
subsequent higher peak flows and velocities impart a greater tractive force on the stream bank,
which results in a higher erosion rate than the stable pre-development rate.
Map F illustrates the jurisdictions which experience increased growth rate and the channels
susceptible. As illustrated, the City of Dallas and Rowlett are the jurisdictions in the Dallas County
Local Mitigation Strategy most affected by Stream Bank Erosion and thus have identified
mitigation action items in Chapter 4.
Dam Failure A dam is defined as a barrier constructed across a watercourse for the purpose of
storage, control, or diversion of water. Dams typically are constructed of earth, rock, concrete, or
mine tailings. A dam failure is an accidental or unintentional collapse, breach, or other failure of
an impoundment structure that results in downstream flooding. Because dams are man-made
structures, dam failures are usually considered technological hazards. However, since most dam
failures result from prolonged periods of rainfall, they are often cited as secondary or cascading
effects of natural flooding disasters and are not named as the primary hazard that causes
disaster declarations.
Dam Failure is a hazard recognized to have a predictable vulnerability area. There are eleven
high hazard dams in the Dallas County Local Mitigation Strategy according to the National
Inventory of Dams which will be further addressed. (As demonstrated through Maps G-G 11)
These dams are located in (and affect) the cities of: Dallas and Irving The following cities are not
at risk to a high hazard dam: Cedar Hill, Coppell, Unincorporated Dallas County, DeSoto,
Duncanville, Farmers Branch, Lancaster, Rowlett and Sachse.
These jurisdictions recognize the need to conduct Dam Inundation Studies and to coordinate with
Dam owners to mitigate the affects of Dam Failure. Once the jurisdiction has an understanding of
the current safety status of the dam, mitigation action items may be identified and prioritized for
future funding consideration.
City of Dallas There are several Dams which have been identified as High Hazard according to
the National Inventory of Dams.
The Cherrybrook Lake Dam is owned by the City of Dallas and subject to Dam Safety Inspections
by TCEQ. The city is in the process of developing Operation and Maintenance manuals to assist
the Streets and Services Department with maintenance in the future. Currently no serious
deficiencies have been found. While there are Safety inspections, a data deficiency has been
recognized and action items have been identified on 4- 8.
The Woody Branch Detention Basin Dam (also known as the Boulder Park Dam) is owned by the
City of Dallas and subject to Dam Safety Inspections by TCEQ. The city is in the process of
developing Operation and Maintenance manuals to assist the Streets and Services Department
with maintenance in the future. Currently no serious deficiencies have been found. While there
are Safety inspections, data deficiency has been recognized and action items have been
identified on 4-8 .
The Lake Cliff Dam is an earthen embankment topped by Colorado Boulevard, a four-lane
collector. This structure is inspected, and maintained by the Street and Services department. No
flood analyses have been done and there are no recommendations for improvements. A data
deficiency has been recognized and action items have been identified on 4-8.
North Central Texas Council of Governments 3-11
Regional Mitigation Strategy
White Rock Dam is maintained by the Dallas Water Utilities. An analysis and maintainance
program has recently been undertaken. A data deficiency has been recognized and action items
have been identified on 4-8.
Mountain Creek Dam, North Lake Dam and Prestonwood Dam are privately owned. The
jurisdiction recognizes the need to establish a relationship with the owners in order to ensure the
citizens safety. A data deficiency has been recognized and action items have been identified on
4-8 .
City of Irving While the City of Irving does not have a dam it is assumed that the inundation zone
for the North Lake Dam would affect the jurisdictional area for the City of Irving. While the
100/500 year flood zones do not over top the levee at Valley Ranch it is recognized that the
inundation zone would exceed the 100/500 year flood zones. The main dam inundation zone
travels down the Grapevine Creek and over tops the levee but would not destroy it. The saddle
dam inundation zone travels directly into Valley Ranch. A data deficiency has been recognized
and action items have been identified on 4-32.
Cottonwood Creek Dam is privately owned. The jurisdiction recognizes the need to establish a
relationship with the owner in order to ensure the citizens safety. A data deficiency has been
recognized and action items have been identified on 4-32.
Levee Failure Levees are earthen embankments whose primary purpose is to furnish flood
protection from seasonal high water for a few days or weeks a year. Levees are broadly classified
as either urban or agricultural because of the different requirements for each. Urban levees
provide protection from flooding in communities, including their industrial, commercial, and
residential facilities. Agricultural levees provide protection from flooding in lands used for
agricultural purposes.
Based on information contained in the Corps of Engineers reports; “Upper
Trinity River Reconnaissance Report” and 1995 Information Paper – A Benefit-Cost Analysis,
Upper Trinity River Basin, Texas, “Natural Disaster Procedures Under PL 84-99 (Supplement A to
ER 500-1-1), and various FEMA “Flood Insurance Study” reports, The Trinity River is formed at
the confluence of the West Fork and Elm Fork, just to the west of downtown Dallas, and the
majority of the levees are located on these conveyances or their major tributaries. The Code of
Federal Regulations, 44 CFR Section 65.10, outlines the requirements for mapping areas
protected by levee systems. For the purposes of the National Flood Insurance Program (NFIP),
FEMA will only recognize in its flood hazard and risk mapping effort those levee systems that
meet, and continue to meet, minimum design, operation, and maintenance standards that are
consistent with the level of protection from the base flood.
The following table displays the Flood Protection Levee Systems in Dallas County, it is based on
information shown on FEMA published Flood Insurance Studies and described on Flood
Insurance Rate Maps (FIRM’s) published for the NCTCOG planning area. FEMA requires that
levee systems must be designed, constructed and maintained to the minimum standards of the
National Flood Insurance Program and protect to the 100-year flood event before that can be
mapped as providing flood protection. See map H for a spatial representation of the levee
systems in the Dallas County area.

The risk of levee failure from the base flood event is minimal for the levee systems listed above.
However, there is a greater risk of levee failure or levee systems being overtopped for flood
events that exceed the base flood event. The three foot freeboard required by FEMA provides a
greater safety factor, but major floods of long duration such as the 1993 Mississippi River Flood
can result in major damage and potential loss of life.
The Information Paper – “A Benefit-Cost Analysis, Upper Trinity River Basin, Texas”, 1995,
prepared by the US Army Corps of Engineers Fort Worth District states that if the Standard
Project Flood were to occur (1995) more than 12,000 homes and more than 140 million square
feet of commercial property would be damaged, resulting in over $4 billion in flood damages and
untold loss of life.
While no record could be found of any previous major levee failures in Dallas County the point
must be made that increasing development both upstream and downstream of the region’s
existing levees are likely to be reducing the flood protection capabilities of these levees even for
the base flood event. As a result of recent studies showing the devastating impacts of the
Standard Project Flood and because development has likely resulted in incremental reductions in
base flood protection capabilities, the risk of a levee failure hazard is sufficient enough to merit
mitigation consideration as can be seen in Chapter 4 where each of the participating jurisdictions
with Levee Systems have identified Mitigation Action Projects.

3.2 Location of Hazards
The following maps illustrate the location of the hazards in Dallas County. The following maps
concerning Tornados, Hail Events, and High Wind Events are in reverence to previous events as
they have the potential to occur equally throughout the county. Lightning, Winter Storms, Summer
Heat, Drought have the potential to occur equally throughout the county and their previous events
data is not represented by a map.

Map F Projected Stream Bank Erosion
This map shows local area watersheds of the upper Trinity River which are susceptible to
increased rates of stream bank erosion as a consequence of population growth and new
construction. Stream bank erosion occurs when development of the contributing
watershed results in increased impervious area, reduced infiltration, increased runoff, and
increased flood frequencies. These subsequent higher peak flows and velocities impart a
greater tractive force on the stream bank, which results in a higher erosion rate that the
stable pre-development rate.

These winds are very unlikely. The small area of damage they
might produce would probably not be recognizable along with the
mess produced by F4 and F5 wind that would surround the F6
winds. Missiles, such as cars and refrigerators would do serious
secondary damage that could not be directly identified as F6
damage. If this level is ever achieved, evidence for it might only
be found in some manner of ground swirl pattern, for it may never
be identifiable through engineering studies
On February 1, 2007, the Fujita scale was decommissioned in favor of the more accurate
Enhanced Fujita Scale, which replaces it. None of the tornadoes recorded on or before January
31, 2007 will be re-categorized. Therefore maintaining the Fujita scale will be necessary when
referring to previous events.

The Enhanced Fujita Scale is representative of the damage from tornadoes this community has
faced in the past and will no doubt face in the future. For example, according to the National Data
Climatic Data Center, in January of 1996 a supercell thunderstorm embedded within a squall line
that moved through Dallas County produced 7 short track tornadoes and a downburst in the
southern portion of the county. Substantial damage occurred in the Desoto and Lancaster areas
with an estimated $1.5 million in damage to businesses, homes and public buildings. An in-depth
damage survey revealed 7 individual tracks in Dallas County

Winter Storm: wind chill, volume of ice, volume of snow;
The Wind Chill temperature you have undoubtedly heard of is simply a measure of how cold the
wind makes real air temperature feel to the human body. Since wind can dramatically accelerate
heat loss from the body, a blustery 30° day would feel just as cold as a calm day with 0°
temperatures. The index was created in 1870, and on November 1, 2001, the National Weather
Service released a more scientifically accurate equation, which we use today. Here is a chart for
calculating wind chill. (Please note that it is not applicable in calm winds or when the temperature
is over 50°.)
Source: National Weather Service and NOAA
The Wind Chill Chart displays the Frostbite Times in regards to Temperature and Wind. This
chart allows the communities to prepare for Severe Winter Storm or an Ice event. These events
are infrequent but can cause damage. The primary areas of concern are on bridges and
roadways. For example, according to the National Climatic Data Center, in February of 1996
A cold arctic air mass that spread into North Texas (including Dallas County) on the 1st was
overriden by warm, moist air as a strong upper level disturbance approached from New Mexico.
Rain, freezing rain and sleet developed over the area. As the cold air deepened, all the
precipitation turned to snow. By midday on the 2nd, the entire North Texas area (including Dallas
County) had received a coating of ice and much of the region additionally received 1 to 3 inches
of snow. Thousands of automobile accidents resulted in numerous indirect injuries and several
indirect deaths. It is expected for Severe Winter Storms and Ice to be a hazard in the future, this
Wind Chill Chart allows the planning communities to prepare and mitigate for the hazard.

The Heat Index chart displays the relative danger in regards to Air Temperature and Relative
Humidity. Extreme Heat is a hazard this community has faced in the past and will no doubt face in
future summer time seasons and the combination of high temperatures and high humidity’s
prompt heat Advisory’s. For example, in August of 2007 high temperatures were over 100
degrees with heat index values reaching 110-115 degrees. This resulted in one death and several
heat related illnesses. This chart allows communities to assess the citizen’s danger in regards to

Drought: Palmer Index
Palmer Drought Severity Index (PDSI)
In 1965, Palmer developed an index to "measure the departure of the moisture supply". Palmer
based his index on the supply-and-demand concept of the water balance equation, taking into
account more than only the precipitation deficit at specific locations. The objective of the Palmer
Drought Severity Index (PDSI), as this index is now called, was to provide a measurement of
moisture conditions that were "standardized" so that comparisons using the index could be made
between locations and between months.
The Palmer Drought Index is based on precipitation and temperature. The Palmer index can
therefore be applied to any site for which sufficient precipitation and temperature data is
available.
The Palmer Index varies roughly between -4.0 and +4.0. Weekly Palmer Index values are
calculated for the Climate Divisions during every growing season and are on the World Wide Web
from the Climate Prediction Center.
Source: http://drought.unl.edu/whatis/indices.htm
Drought conditions do occur in this community. The last event was during a widespread Drought
in 2006. The PDSI Classification allows community planners to anticipate the effects of Drought
and plan preparedness and mitigation activities for future events as they will likely occur.
PDSI Classifications for Dry and Wet Periods
4.00 or more Extremely wet
3.00 to 3.99 Very wet
2.00 to 2.99 Moderately wet

Flood Zones
The 100-year or Base Floodplain. There are six types of A zones:
A The base floodplains mapped by approximate methods, i.e., BFEs are
not determined. This is often called an unnumbered A zone or an
approximate A zone.
A1-30 These are known as numbered A zones (e.g., A7 or A14). This is the
base floodplain where the firm shows a BFE (old format).
AE The base floodplain where base flood elevations are provided. AE zones
are now used on new format FIRMs instead of A1-30 zones.
AO The base floodplain with sheet flow, ponding, or shallow flooding. Base
flood depths (feet above ground) are provided.
AH Shallow flooding base floodplain. BFE's are provided.
A99 Area to be protected from base flood by levees or Federal flood
protection systems under construction. BFEs are not determined.
Zone A
AR The base floodplain that results from the de-certification of a previously
accredited flood protection system that is in the process of being restored
to provide a 100-year or greater level of flood protection
V The coastal area subject to velocity hazard (wave action) where BFEs
are not determined on the FIRM. Zone V and VE VE The coastal area subject to velocity hazard (wave action) where BFEs
are provided on the FIRM.
Zone B and
Zone X
(shaded)
Area of moderate flood hazard, usually the area between the limits of the 100-year
and the 500-year floods. B zones are also used to designate base floodplains or
lesser hazards, such as areas protected by levees from the 100-year flood, or
shallow flooding areas with average depths of less than one foot or drainage
areas less than 1 square mile.
Zone C and
Zone X
(unshaded)
Area of minimal flood hazard, usually depiction FIRMs as exceeding the 500-year
flood level. Zone C may have ponding and local drainage problems that do not
warrant a detailed study or designation as base floodplain. Zone X is the area
determined to be outside the 500-year flood.
Zone D Area of undetermined but possible flood hazards.
Flood hazard areas are identified as a Special Flood Hazard Area (SFHA). SFHA are defined as
the area that will be inundated by the flood event having a 1-percent chance of being equaled or
exceeded in any given year. The 1-percent annual chance flood is also referred to as the base
flood or 100-year flood. SFHAs are labeled as Zone A, Zone V, and Zone VE, Moderate flood
hazard areas, labeled Zone B or Zone X are the areas between the limits of the base flood and
the 0.2-percent-annual-chance (or 500-year) flood. The areas of minimal flood hazard, which are
the areas outside the SFHA and higher than the elevation of the 0.2-percent-annual-chance
flood, are defined as Zone C or Zone X. These flood zone identifications allow planners to
determine appropriate Landuse in designated zones. The planning communities are participants
in the National Flood Insurance Program and actively take measures to plan Landuse. The
communities are subject to flash flooding hazards such as the event in 2000 which resulted in
one fatality and $25,000 in property damage.

3.4 Previous Events Data
The following table is the previous events data according to the National Climatic Data Center
reported in Dallas County, Texas between 01/01/1950 and 03/31/2007. For those hazards which
have the potential to affect the county equally all data provided by the National Climatic Data
Center has been included. The belief is that hazards do not stay within jurisdictional boundaries
and thus it is important to be aware of occurrences that have impacted neighboring jurisdictions
to further assess the DaLMS participating jurisdictions risks.
Stream Bank Erosion There is no recorded information or known history on previous
occurrence/history of Stream Bank Erosion within Dallas County.
Dam Failure There is no recorded information or known history on previous occurrence/history
of Dam Failure within Dallas County.
Levee Failure The known Levee Failure history: In 1991, a levee breach occurred in
unincorporated Dallas County near Beltline and Bilindsay S of Malloy Bridge Road that caused a
damaged roadway, homes, and caused three drowning deaths. The Levee is privately owned
and property owner is responsible for maintenance.
Earthquake During October 31 to November 1, 2008 there were seven earthquakes ranging
from 2.5 to 3.0 on the Richter scale in Dallas County. Due the recent event there is no research
currently available on these Earthquakes.

3.6 Assessing Vulnerability
Identifying Structures
Map K Identifies the Critical Structures (Police Stations, Fire Stations, City Hall, and Emergency
Operations Centers) in Dallas County in relation to the 500 year Flood Zone.
Structures located in the 500 Year Flood Zone will be assessed further for potential mitigation
action items to protect the property from flooding events. A cost-benefit analysis will be
conducted and mitigation action items will be chosen based upon effectiveness of protection to
life and property as well as the jurisdictions ability to serve the community.
Identifying vulnerability and the types and numbers of existing and future buildings,
infrastructure, and critical facilities located in other identified hazard areas is not known at this
time but will be achieved through mitigation measures.
Estimating Potential Dollar Loss
Each participating jurisdiction will develop a methodology for estimating the potential dollar loss
of the existing buildings, infrastructure, and critical facilities located in the identified and future
identified hazard areas.
Analyzing Development Trends
Each participating jurisdiction in the Dallas County Local Mitigation Strategy has city zoning
ordinances which establish a land development trend of building outside of the flood plains.
Mitigation measures and the Dallas County Local Mitigation Strategy will continue to be used
and assessed in future city plan development.

4.2 Action Items
Each participating jurisdiction’s Hazard Mitigation Team in the Dallas County Local Mitigation
Strategy collaboratively created action items based upon the direction of the city/county as
identified in Capitol Improvement Plans, special projects, and available funding such as grants.
Action Items answer the following questions:
1. Action Item Title
2. Hazard(s) Addressed
3. Goal
4. Priority
5. Estimated Cost
6. Potential Funding Sources
7. Lead Agency/Department Responsible
8. Implementation Schedule
Hazard Mitigation Team representatives met as a Local Mitigation Strategy to further analyze the
mitigation needs as a county.

Chapter Five Plan Maintenance Process
Monitoring The NCTCOG Emergency Preparedness Department (NCTCOG EP) will be the
coordinating point of contact for monitoring the Dallas County Local Mitigation Strategy. In
coincidence with the anniversary date, annually NCTCOG EP will solicit monitoring reports from
participating jurisdictions. The reports will include progress on the implementation of the strategy
and mitigation actions. For the purpose of monitoring each jurisdiction’s representative will tour
mitigation sites, report on the project schedule, and its’ implementation.
Evaluating The mitigation plan will be evaluated annually, coinciding with the anniversary date;
NCTCOG EP department will function as the coordinating point of contact for the participating
jurisdictions. Each jurisdiction will evaluate their data in effort to take into account vulnerabilities
which have changed and to ensure that goals and objectives are kept current.
The plan will be evaluated by the following criteria:
Is the natural hazard analysis accurate?
Are the goals and objectives being met through mitigation projects or other city planning
mechanisms?
Are the mitigation projects identified relevant to current resources and situation?
Are mitigation projects being effectively implemented?
Is the hazard mitigation plan being incorporated into other city planning processes?
What are the results of public comments?
Updating Prior to the five-year anniversary and in accordance with 44 CFR Section 201.6 the
Dallas County Local Mitigation Strategy will be updated. The update process will be conducted by
NCTCOG EP department. NCTCOG EP department will utilize the annual monitoring and
evaluation reports to make changes to the mitigation plan, vulnerability analysis, goals, and action
items. Participating jurisdictions will meet twice to discuss the success and changes to the Dallas
County Local Mitigation Strategy and after an opportunity for public comment, the Dallas County
Local Mitigation Strategy will then be resubmitted for update approval.
Plan Incorporation into Existing Planning Mechanisms The participating jurisdictions in the
Dallas County Local Mitigation Strategy recognize the importance of incorporating mitigation
activities throughout city planning efforts. Other local planning mechanisms have been identified
to include; Building codes, Planning and Zoning Ordinances, Fire Codes, NFIP, and Capital
Improvement Plans. During annual evaluations of the identified planning mechanisms the Local
Mitigation Strategy’s Goals and Mitigation Action Items will be taken into consideration.
During strategic planning cycles, members from the Hazard Mitigation Teams will be available to
provide data and input as the County Commissioner’s Court and City Councils provide direction
as to what areas of public safety and hazard mitigation they would like to see addressed and
funded. By funding mitigation strategies each year through normal and CIP processes, it is hoped
that future impacts of hazards can be lessened, saving lives and money for the Cities and
Citizens in the Dallas County Local Mitigation Strategy.
The Dallas County Local Mitigation Strategy participants currently have an Emergency Operation
Plan. The DaLMS will support Annex P: Hazard Mitigation of the EOP for future submissions.
DaLMS participants will be adopting the approved plan and will incorporate it into their existing
local plans used for zoning and land use. All participants will follow local laws and guidelines
when incorporating the DaLMS in their existing plans that are relevant to Hazard Mitigation. Each
incorporating mechanism will follow their local laws or guidelines necessary for implementation
through open forum public meetings. Each participant will monitor the incorporation into other
planning mechanisms and report the success or failure in the annual report to NCTCOG EP. With
each update, all participants will be informed of the changes. Also, the DaLMS will be
incorporated into the State of Texas Hazard Mitigation Plan through the risk assessment and
mitigation strategies during their updating process every three years.
5-2 Dallas County
Chapter Five1
For example, the City of Lancaster will take into consideration the identified mitigation goals and
projects during funding allocation and review of the Capitol Improvement Plan. The DaLMS risk
assessment and mitigation goals will be reviewed and implemented as appropriate when the City
of Farmer’s Branch updates Building and Zoning Ordinances. During City Ordinance reviews the
City of Cedar Hill will review the DaLMS goals and objectives to be implemented as appropriate.
During the annual review of the City of Duncanville’s Capitol Improvement Plan the city will
incorporate mitigation goals and projects as appropriate to budget approval.
Continued Public Involvement The Dallas County Local Mitigation Strategy recognizes the
importance of public input for plan success. To continue to engage the public in the planning
process, the completed Hazard Mitigation Action Plan will be posted on the NCTCOG Emergency
Preparedness website as well as participating jurisdiction’s websites. The Dallas County Local
Mitigation Strategy will also be on file for public review at the City Libraries. The public will be
encouraged to review the planning document and provide comments to the appropriate
Emergency Management Coordinator. With each plan update, a public hearing will be held to
seek comment from interested citizens and business owners relating to the Dallas County Local
Mitigation Strategy. The public comments are an important asset in mitigation planning as it
allows the Hazard Mitigation Teams to gauge where the community finds hazard vulnerability and
need for mitigation. Public comments will be used to make appropriate changes and guide
direction in implementing mitigation strategies.
