IN REPLY REFER TO:
Case No.: 99-06-479P
Community: City of Coppell, TX
Community No.: 480170
Panel Affected: 0010 E
Effective Date of M~¥ 2 3 2001
This Revision:
' 102-I-A-C
Dear Mayor Sheehan:
This responds to a request that the Federal Emergency Management Agency (FEMA) revise the effective
Flood Insurance Rate Map (FIRM) and Flood Insurance Study (FIS) report for your community in
accordance with Part 65 of the National Flood Insurance Program (NFIP) regulations. In a letter dated
December 8, 1998, Mr. Kenneth M. Griffin, P.E., Director of Engineeringand Public Works, City of
Coppell, requested that FEMA revise the FIRM and FIS report to show the effects of channelization
along a bypass channel of Grapevine Creek from approximately 880 feet downstream to approximately
400 feet downstream of the St. Louis Southwestern Railway (SLSR) and construction of two footbridges
across the main channel of Grapevine Creek at approximately 900 feet downstream and approximately
725 feet downstream of the SLSR, respectively. This request also incorporated more detailed
topographic information for Grapevine Creek from Bethel Road to the SLSR. This request follows up on
a Conditional Letter of Map Revision issued on June 7, 1994.
All data required to complete our review of this request were submitted with letters from Mr. William A.
Anderson, Vice President, and Ms. Rhonda M. Hurst, E.I.T., both with Dowdey, Anderson and
Associates, Inc.; and Mr. Griffin.
We have completed our review of the submitted data and the flood data shown on the effective FIRM
and FIS report. We have revised the FIRM and FIS report to modify the elevations and floodplain and
floodway boundary delineations of the flood having a 1-percent chance of being equaled or exceeded in
any given year (base flood) along Grapevine Creek from Bethel Road to approximately 300 feet
upstream of Southwestern Boulevard. As a result of the modifications, the Base Flood Elevations
(BFEs) for Grapevine Creek increased, and the widths of the Special Flood Hazard Area (SFHA), the
area that would be inundated by the base flood, and the regulatory floodway increased in some areas and
decreased in other areas. All BFE increases are a result of more detailed topographic information. The
modifications are shown on the enclosed annotated copies of FIRM Panel 0010 E, Profile Panel 05P, and
affected portions of the Floodway Data Table. This Letter of Map Revision (LOMR) hereby revises the
above-referenced panel of the effective FIRM and the affected portions of the FIS report, both dated
April 15, 1994.
The modifications are effective as of the date shown above. The map panel listed above and as modified
by this letter will be used for all flood insurance policies and renewals issued for your community.

*Referenced to the National Geodetic Vertical Datum, rounded to the nearest whole foot
Public notification of the proposed modified BFEs will be given in the Coppell Gazette on or about
February 15 and February 22, 2001. A copy of this notification is enclosed. In addition, a notice of
changes will be published in the Federal Register. Within 90 days of the second publication, in the
Coppell Gazette, any interested party may request that FEMA reconsider the determination made by this
LOMR. Any request for reconsideration must be based on scientific or technical data. All interested
parties are on notice that, until the 90-day period elapses, the determination to modify the BFEs
presented in this LOMR may itself be modified.
Because this LOMR will not be printed and distributed to primary users, such as local insurance agents
and mortgage lenders, your community will serve as a repository for these new data. We encourage you
to disseminate the information reflected by this LOMR throughout the community, so that interested
persons, such as property owners, local insurance agents, and mortgage lenders, may benefit from the
information. We also encourage you to prepare a related article for publication in your community's
local newspaper. This article should describe the assistance that officials of your community will give to
interested persons by providing these data and interpreting the NFIP maps.
We are processing a revised FIRM and FIS report for Dallas County in our countywide format; therefore,
we will not physically revise and republish the FIRM and FIS report for your community to incorporate
the modifications made by this LOMR at this time. Preliminary copies of the countywide FIRM and FIS
report, which present information from the effective FIRMs and FIS reports for your community and
other incorporated communities in Dallas County, were submitted to your community for review on
July 30, 1999, and September 7, 2000. Please note that updated road base information for your
community has been incorporated into the Revised Preliminary FIRM. For display purposes, the updated
road base information is also shown on the enclosed annotated copy of FIRM Panel 0010 E. We will
incorporate the modifications made by this LOMR into the countywide FIRM and FIS report before they
become effective.
The floodway is provided to your community as a tool to regulate floodplain development. Therefore,
the floodway modifications described in this LOMR, while acceptable to FEMA, must also be acceptable
to your community and adopted by appropriate community action, as specified in Paragraph 60.3(d) of
the NFIP regulations.
This LOMR is based on minimum floodplain management criteria established under the NFIP. Your
community is responsible for approving all floodplain development and for ensuring all necessary
permits required by Federal or State law have been received. State, county, and community officials,
based on knowledge of local conditions and in the interest of safety, may set higher standards for
3
construction in the SFHA. If the State, county, or community has adopted more restrictive or
comprehensive floodplain management criteria, these criteria take precedence over the minimum NFIP
criteria.
The basis of this LOMR is, in whole or in part, a channel modification/bridge project. NFIP regulations,
as cited in Paragraph 60.3(b)(7), require that communities ensure that the flood-carrying capacity within
the altered or relocated portion of any watercourse is maintained. This provision is incorporated into
your community's existing floodplain management regulations. Consequently, the ultimate
responsibility for maintenance of the modified channel and bridges rests with your community.
This determination has been made pursuant to Section 206 of the Flood Disaster Protection Act of 1973
(Public Law 93-234) and is in accordance with the National Flood Insurance Act of 1968, as amended
(Title XIII of the Housing and Urban Development Act of 1968, Public Law 90-448), 42 U.S.C.
4001-4128, and 44 CFR Part 65. Pursuant to Section 1361 of the National Flood Insurance Act of 1968,
as amended, communities participating in the NFIP are required to adopt and enforce floodplain
management regulations that meet or exceed minimum NFIP criteria. These criteria are the minimum
and do not supersede any State or local requirements of a more stringent nature. This includes adoption
of the effective FIRM to which the regulations apply and the modifications described in this LOMR.
Our records show that your community has met this requirement.
A Consultation Coordination Officer (CCO) has been designated to assist your community. The CCO
will be the primary liaison between your community and FEMA. For information regarding your CCO,
please contact:

FEMA makes flood insurance available in participating communities; in addition, we encourage
communities to develop their own loss reduction and prevention programs. Through the Project
Impact: Building Disaster Resistant Communities initiative, launched by FEMA Director James Lee
Witt in 1997, we seek to focus the energy of businesses, citizens, and communities in the United States
on the importance of reducing their susceptibility to the impact of all natural disasters, including floods,
hurricanes, severe storms, earthquakes, and wildfires. Natural hazard mitigation is most effective when
it is planned for and implemented at the local level, by the entities who are most knowledgeable of local
conditions and whose economic stability and safety are at stake. For your information, we are enclosing
a copy of a pamphlet describing this nationwide initiative. For additional information on ?rojectlmpact,
please visit our website at www. fema.gov/impact.
If you have any questions regarding floodplain management regulations for your community or the NFIP
in general, please call the CCO for your community at the telephone number cited above. If you have
any questions regarding this LOMR, please call our Map Assistance Center, toll free, at

CHANGES ARE MADE IN DETERMINATIONS OF BASE FLOOD ELEVATIONS FOR THE CITY
OF COPPELL, DALLAS COUNTY, TEXAS, UNDER THE NATIONAL FLOOD INSURANCE
PROGRAM
On April 15, 1994, the Federal Emergency Management Agency identified Special Flood Hazard
Areas (SFHAs) in the City of Coppell, Dallas County, Texas, through issuance of a Flood Insurance Rate
Map (FIRM). The Mitigation Directorate has determined that modification of the elevations of the flood
having a 1-percent chance of being equaled or exceeded in any given year (base flood) for certain
locations in this community is appropriate. The modified Base Flood Elevations (BFEs) revise the FIRM
for the community.
The changes are being made pursuant to Section 206 of the Flood Disaster Protection Act of 1973 (Public
Law 93-234) and are in accordance with the National Flood Insurance Act of 1968, as amended
(Title XIII of the Housing and Urban Development Act of 1968, Public Law 90-448), 42 U.S.C.
4001-4128, and 44 CFR Part 65.
A hydraulic analysis was performed to incorporate the effects of ehannelization along a bypass channel of
Grapevine Creek from approximately 880 feet downstream to approximately 400 feet downstream of the
St. Louis Southwestern Railway; construction of two footbridges across the main channel of Grapevine
Creek at approximately 900 feet downstream and approximately 725 feet downstream of the St. Louis
Southwestern Railway, respectively; and more detailed topographic information for Grapevine Creek
from Bethel Road to the St. Louis Southwestern Railway. This has resulted in a revised delineation of the
regulatory floodway, increases and decreases in SFHA width, and increased BFEs for Grapevine Creek
from Bethel Road to approximately 300 feet upstream of Southwestern Boulevard. The table below
indicates existing and modified BFEs for selected locations along the affected lengths of the flooding
source(s) cited above.

Under the above-mentioned Acts of 1968 and 1973, the Mitigation Directorate must develop criteria for
floodplain management. To participate in the National Flood Insurance Program (NFIP), the community
must use the modified BFEs to administer the floodplain management measures of the NFIP. These
modified BFEs will also be used to calculate the appropriate flood insurance premium rates for new
buildings and their contents and for the second layer of insurance on existing buildings and contents.
Upon the second publication of notice of these changes in this newspaper, any person has 90 days in
which he or she can request, through the Chief Executive Officer of the community, that the Mitigation
Directorate reconsider the determination. Any request for reconsideration must be based on knowledge of
changed conditions or new scientific or technical data. All interested parties are on notice that until the
90-day period elapses, the Mitigation Directorate's determination to modify the BFEs may itself be
changed.

PROJECT IMPACT
Building a Disaster Resistant Connnunity
BACKGROUND
PROJECT IMPACT is an ~e ~eVeloped by FEMA Director james Lee W'~ to challmge the
country to uader~ake actions that protect families, businesses and communities by reducing the
effects of natural disasters. This initiative inducles a national awareness campait~ the selection of
pilot communities that demonmate the ~ of hazard mitigation through a parmershi-~
approach, and an outreach effort to .... t'
huinesses and comnmnmes using a ne~ guidebook that o fie. rs
a formula for a community or Ixtsiness to follow to become disaster resistant.
The 'increasing number and severity of natural disasters the past decade demands that action be
taken to reduce the threat that hurricanes, severe storms, earthquakes, floods and wildfires impose
upofi the economic stabili~, economic future and safety of the dri-~-ns of the U.5. As the federal
agency responsible for enmgeucy management, FEMA is committed to reduiing disaster losses by
focusing the eaexgy of businesses, dtizzns, and communities in the U.S. on the.importance of
reducing their susceptib/~y to the' ;,Wact of renu-al disasters.
There are three primary tenets of the PROJECT IIVlPACT initiative:
· Mitigation is a local issue. It is best addressed by a local partnership that involves
government, businesses and private citizens.
Private sector participation is essential Disasters threaten the economic and commercial
growth of our cities, towns, villages and counties. Without the participation of the private
sector, comprehensive solutions will not be developed.
· Mitigation is a long-term effort that requires long-re, m investment. Disaster losses will not
be eliminated overnight.
PI LOT COMMUNITIES
Director Witt and FEMA have worked closely with seven communities throughout the U.S. to
develop a PROJECT IMPACT plan that localities, businesses and dtizens can follow to build
disaster resistant communities where they live and work. Director Win will parddpate in events in
each of these communities to congratulate them on their foresight, commitment, and contribution
to a disaster resistant nadon.
PROJECT IMPACT GUIDEBOOK
The guidebook presents that steps a community can take to become disaster resistant. It a/so
provides examples of the actions and resources available to accomplish this. goal
