ARTICLE VIII: FLOODPLAIN PROVISIONS
DIVISION 1: PURPOSE, OBJECTIVES AND DEFINITIONS
Sec. 7-301 FINDINGS OF FACT.
(a) The flood hazard areas of Fort Worth are subject to periodic inundation which results in loss
of life and 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.
(b) These flood losses are created by the cumulative effect of obstructions in floodplains which
cause an increase in flood heights and velocities, and by the occupancy of flood hazard areas by
uses vulnerable to floods and hazardous to other lands because they are inadequately elevated,
floodproofed or otherwise protected from flood damage.
Sec. 7-302 STATEMENT OF PURPOSE.
It is the purpose of this article to promote the public health, safety and general welfare and to
minimize public and private losses due to flood conditions in specific areas, by the provisions
provided herein to:
(a) Protect human life and health;
(b) Minimize the need for future expenditures of public funds for costly flood control projects;
(c) Minimize the need for rescue and relief efforts associated with flooding and that are generally
undertaken at the expense of the general public;
(d) Minimize prolonged business interruptions;
(e) Minimize damage to public facilities and utilities, such as water and gas mains, electric,
telephone and sewer lines, streets and bridges, that are located in floodplains;
Chapter 7, Article VIII Ordinance No.
Page 2 of 30
(f) Help maintain a stable tax base by providing for the sound use and development of flood -
prone areas in such a manner as to minimize potential future flood blight areas;
(g) Ensure that property owners, occupants, and potential property owners are aware of property
located in flood hazard areas; and
(h) Require that persons who knowingly occupy flood -prone areas assume full responsibility for
their actions.
Sec. 7-303 METHODS OF REDUCING FLOOD LOSSES.
In order to accomplish reduction of flood loss, this article uses the following methods:
(a) Restrictions or prohibitions to uses that are dangerous to health, safety or property in times
of flood, or cause increases in erosion, flood heights or velocities;
(b) Requiring that uses vulnerable to floods, including public facilities which serve such uses,
be protected against flood damage at the time of initial construction;
(c) Controlling the alteration of natural floodplains, stream channels and natural protective
barriers, which are involved in the accommodation of flood waters;
(d) Control filling, grading, dredging, excavation and other development which may increase
flood damage;
(e) Preventing or regulating the construction of flood barriers which will unnaturally divert
flood waters or which may increase flood -hazards to other lands;
(f) Controlling development which would cause greater erosion or potential flood damage such
as grading, dredging, excavation, and filling;
(g) Imposing a regulatory 1% annual chance floodplain that requires using the ultimate
development of the watershed to determine the fully developed base flood elevation. New
developments must be constructed above this elevation.
(h) Using any other method reasonably calculated to accomplish the purpose of this article and
to promote the public health, safety and general welfare.

Sec. 7-318 ESTABLISHMENT OF FLOODPLAIN DEVELOPMENT PERMIT.
A floodplain development permit shall be required to ensure compliance with the provisions of
this article. No structure or land in an area of special flood hazard shall hereafter be located,
altered, have its use changed, or otherwise be developed unless a floodplain development permit
has been issued, pursuant to the terms of this floodplain article. Proposed work must be started
within six (6) months of the date of approval of a floodplain development permit, otherwise the
permit will become null and void. The floodplain development permit shall expire and have no
further effect twenty-four (24) months from the date of the approval of the floodplain development
permit unless an extension is approved by the floodplain administrator. Extensions shall be
requested in writing to the floodplain administrator with justifiable cause demonstrated. If the
extension is not approved then the applicant must apply for a new floodplain development permit
before beginning or continuing development within the floodplain.
When issued, the floodplain permit shall be valid only as to the applicant (i.e. Property owner and/
or engineer) to whom it was originally issued and shall not be transferred to another
applicant. A new floodplain development permit must be obtained by the new applicant. Any
significant revisions to the approved development covered by the floodplain development permit
will require additional review for approval. The determination that revisions are significant are
within the discretion of the floodplain administrator.
Building permits, floodplain permits or plat approvals shall not be issued for properties with
unresolved floodplain violations unless the aforementioned permits will remedy the violation.
The floodplain administrator is authorized to suspend or revoke a permit issued under these
regulations whenever the permit is issued in error or on the basis of incorrect, inaccurate or
incomplete information, or in violation of any article or code of the city.
Procedures to obtain floodplain development permit are set forth in § 7-333 of this article.

Sec. 7-332 DUTIES AND RESPONSIBILITIES OF THE LOCAL FLOODPLAIN
ADMINISTRATOR.
Duties and responsibilities of the floodplain administrator shall include, but not be limited to, the
following:
(a) Maintain and hold open for public inspection all records pertaining to the provisions of this
article;
(b) Review permit applications for sites located in, or adjacent to, the regulatory floodplain,
including the placement of manufactured homes, to determine if the proposed development site
will be reasonably safe from flooding;
(c) Review and approve or deny all applications for development permits required by adoption
of this article;
(d) Review permits for proposed development within a floodplain to provide reasonable
assurance that all other necessary permits have been obtained from those federal, state or local
governmental agencies (including § 404 of the Federal Water Pollution Control Act Amendments
of 1972, 33 U.S.C. 1334) from which prior approval is required;
(e) Review all applications for permits for development within a floodplain to determine if the
proposed development is located in the floodway. If located in the floodway, assure that the
encroachment provisions of § 7-350(a) are met;
(f) Interpret, as needed, the exact location of the boundaries of the areas of special flood hazards.
For example, where there appears to be a conflict between a mapped boundary and actual field
conditions, the floodplain administrator shall make the necessary interpretation. The floodplain
administrator shall make such determinations in a reasonably prudent manner. When any such
interpretation results in a determination that an area is not a special flood hazard, the issuance of
any building permits for any part of the area subsequent thereto shall be subject to the applicant's
agreement to indemnify, hold harmless, and defend the City of Fort Worth and the floodplain
administrator for any adverse consequences resulting from or related to such a determination;
(g) Notify, in riverine situations, adjacent communities and the Texas Water Development
Board (TWDB) and also the Texas Commission on Environmental Quality (TCEQ), prior to any
alteration or relocation of a watercourse, and submit evidence of such notification to the Federal
Emergency Management Agency;
(h) Assure that the flood carrying capacity within the altered or relocated portion of any
watercourse is maintained or increased;
(i) When base flood elevation data has not been provided in accordance this article, the
floodplain administrator shall obtain, review and reasonably utilize, any base flood elevation data
and floodway data available from a federal, state or other reliable source, in order to administer
Division 4 of this article;
0) When a regulatory floodway has not been designated, the floodplain administrator must
require that no new construction, substantial improvements or other development (including the
placement of fill) shall be permitted within zones Al-30 and AE on the community's FIRM,
unless it is demonstrated that the cumulative effect of the proposed development, when combined
Chapter 7, Article VIII Ordinance No.
Page 12 of 30
with all other existing and anticipated development, will not increase the water surface elevation
of the base flood more than one foot at any point within the community;
(k) Grant variances in conformance with the provisions of § 7-334, Variance procedures.
(1) Require applicants who submit hydrologic and hydraulic engineering analyses to support
permit applications to submit to FEMA the data and information necessary to maintain the Flood
Insurance Rate Maps when the analyses propose to change discharges, cross sections, base flood

Sec. 7-333 PERMIT PROCEDURES.
(a) Application Requirements:
(1) No person shall proceed with development of property within the floodplain until an
application is submitted and a Floodplain Development Permit (FDP) is issued.
(2) Prior to issuance of the Floodplain Development Permit (FDP), or authorization to excavate
or fill in the floodplain, all required permits must be obtained by the owner from all State and
Federal regulatory bodies with jurisdiction in such matters. A copy of the appropriate agency's
approved permit must be provided to the City with the FDP application.
(3) Application for a Floodplain Development Permit (FDP) must be presented to the
floodplain administrator on forms provided on the City's website. The permit application must
include, but not be limited to, plans to scale showing the location, dimensions, and elevation of
proposed landscape alterations, existing and proposed structures, including the placement of
manufactured homes, and the location of the foregoing in relation to areas of special flood
hazard. Additionally, the following information is required:
a. An Elevation Certificate for structures on property located in or abutting the floodplain. The
certificate must be completed by a registered public land surveyor or professional engineer and
include the elevation in relation, to mean sea level, of the lowest floor including basement, finished
garage and lowest elevation of machinery or equipment servicing the building, of all new and
substantially improved structures. The certificate must be submitted within 60 days of completion
of construction or substantial improvement;
b. Elevation in relation to mean sea level to which any nonresidential structure shall be
floodproofed (floodproofing requirements are set forth in § 7-347(b));
c. Certification from a registered professional engineer or architect that the nonresidential
floodproofed structures shall meet the floodproofing criteria of § 7-347(b);
d. Description of the extent to which any watercourse or natural drainage will be altered or
relocated as a result of proposed development;
e. Valley storage evaluation for sites located within a sump area associated with the Trinity
River levee system. The determination of valley storage impacts consists of a comparison of pre -
project (existing) conditions and post -project conditions. The maximum allowable valley storage
decrease for the 1 % annual chance flood is 0.0%; and
Chapter 7, Article VIII Ordinance No.
Page 13 of 30
f. For existing structures within the floodplain that do not conform to current floodplain
management standards, the Substantial Improvement or Substantial Damage Review Package
must be submitted to obtain the substantial improvement or substantial damage determination.
1. If the proposed work is determined to be a substantial improvement then the entire
structure must be brought into compliance with this article.
2. If the proposed work does not constitute a substantial improvement then the existing
structure may be improved (remodeled) without conforming to requirements in this
article. Once a property has been issued a floodplain development permit using the fifty
(50) percent rule, any additional improvements thereafter will be tracked over a total of
five (5) years. These improvements within the five-year period cannot exceed fifty (50)
percent of the fair market value of the existing structure at the time of issuance of said
first floodplain development permit.
(4) No application shall be accepted for review until the application meets the requirements of
this article, including all necessary documents and supporting information. Applications that do
not include all necessary documentation and supporting information shall be deemed
not complete.
(b) Permit Evaluation. Approval or denial of a floodplain development permit by the
floodplain administrator shall be based on all of the provisions of this article and the following
relevant factors:
(1) The danger to life and property due to flooding or erosion damage;
(2) The susceptibility of the proposed facility and its contents to flood damage and the effect of
such damage on the individual owner;
(3) The danger that materials may be swept on to other lands to the injury of other persons or
property;
(4) The compatibility of the proposed use with existing and anticipated developments;
(5) The safety of access to the property in times of flood for ordinary and emergency vehicles;
(6) The costs of providing governmental services during and after flood conditions including
maintenance and repair of streets and bridges, and public utilities and facilities such as sewer, gas,
electrical and water systems;
(7) The expected heights, velocity, duration, rate of rise and sediment transport of the flood
waters and the effects of wave action, if applicable, expected at the site;
(8) The necessity to the facility of a waterfront location, where applicable;
(9) The availability of alternative locations, not subject to flooding or erosion damage, for the
proposed use;
(10) The relationship of the proposed use to the comprehensive plan and floodplain
management program for that area; and
(11) The cumulative effects of development and the associated loss of stormwater storage
and/or detention; and
Chapter 7, Article VIII Ordinance No.
Page 14 of 30
(12) The impact the development may have on the overall function of the stormwater facilities
and the impact on properties in its own and connecting watersheds. This may include but not be
limited to changes in discharges as a result of changes in impervious cover, velocity, storage, creek
roughness, etc.
(c) If a floodplain development permit application is disapproved, the floodplain administrator
shall notify the applicant in writing of the section and specific requirement of this article with
which the proposed development does not comply and the nature of such noncompliance.
(d) No building permits, inspections, or certificates of occupancy to structures will be issued
unless the terms and conditions of this article are met.
Sec. 7-334 VARIANCE AND APPEAL OF INTERPREATION PROCEDURES.
(a) Variances. Variances may be issued for new construction, and substantial improvements,
and for other development necessary for the conduct of a functionally dependent use provided that
the criteria outlined in subsections (1) through (8) below are met, and the structure or other
development is protected by methods that minimize flood damages during the base flood and
create no additional threats to public safety.
(1) A request for a variance shall be submitted in writing to the floodplain administrator. The
administrator may issue a variance consistent with the provisions of this section.
(2) Prior to the request being considered, at minimum, the following supporting information
shall be forwarded to the floodplain administrator for review and recommendations.
a. Plans drawn to scale showing the nature, location, dimensions and elevations of the property,
existing and proposed structures, fill, storage of materials, floodproofing measures and the
relationship of the above to the location of the channel and floodway and the minimum building
elevation.
b. Furnish the following additional information as is deemed necessary by the floodplain
administrator for the evaluation of the effects of the proposed use upon flood flows and other
factors necessary to render an opinion on the suitability of the proposed use:
(i) Cross -sections showing the channel of the stream, elevation of land areas adjoining each
side of the channel, and cross -sectional areas to be occupied by the proposed development.
(ii) A site plan showing elevations or contours of the ground, pertinent structure, fill or storage
elevations; size, location and spatial arrangement of all proposed and existing streets, water supply,
sanitary facilities, soil types and other pertinent information.
(iii) Profile showing the slope of the bottom of the channel or flow line of the stream.
(iv) Hydraulic information including water surface profiles for a minimum of the 1% annual
chance event for existing and proposed improvements.
(v) Specifications for building construction and materials, floodproofing, filling, dredging,
grading, channel improvement, storage of materials, water supply, and sanitary facilities.
(vi) Photographs showing existing land uses and vegetation upstream and downstream.
(3) Denial of a variance by the floodplain administrator concerning design standards for
floodproofing which have been set forth in a nationally recognized standard acceptable to the city,
Chapter 7, Article VIII Ordinance No.
Page 15 of 30
shall be made to the construction and fire prevention board of appeals. The board may only approve
alternate methods and shall not approve the omission thereof.
(4) Variances may be issued for the reconstruction, rehabilitation or restoration of structures
listed on the National Register of Historic Places or the State Inventory of Historic Places, without
regard to the procedures set forth in the remainder of this article.
(5) Variances may be issued for new construction and substantial improvements to be erected
on a lot of one-half acre or less in size contiguous to and surrounded by lots with existing structures
constructed below the base flood level, provided the relevant factors in § 7-333(b) have been fully
considered. As the lot size increases beyond the one-half acre, the technical justification required
for issuing the variance increases.
(6) Upon consideration of the factors noted above and the intent of this article, the floodplain
administrator or appropriate appeal board may attach such conditions to the granting of variances
as deemed necessary to further the purposes and objectives of this article.
(7) Variances shall not be issued within any designated floodway if any increases in flood levels
during the base flood discharge would result.
(8) A variance shall only be issued upon a determination that:
a. The variance is the minimum necessary considering the flood hazard to accord relief,
b. A showing of good and sufficient cause is made;
c. A determination that failure to grant the variance would result in exceptional hardship to
the applicant; and
d. A determination that the granting of a variance will not result in increased flood heights,
additional threats to public safety, extraordinary public expense, the creation of nuisances, fraud
on or victimization of the public (including future owners) or conflict with existing local laws or
ordinances.
(9) The Floodplain Administrator shall provide a determination to grant or deny a variance
within 30 days from submittal of the variance request, unless additional information was requested
to support the variance request which delays the completion of the review.
(10) The Floodplain Administrator shall provide signed, written notice mailed by certified mail,
return receipt requested, to an applicant prior to the granting of a variance stating that should a
structure be permitted to be built with the lowest floor elevation below the standard minimum floor
elevation, the cost of flood insurance will be commensurate with the increased risk to life and
property -resulting from the reduced lowest floor elevation. Such notice shall be effective upon
deposit in United States mail.
(b) Interpretation. If there is an alleged error in an interpretation of any requirement, decision
or determination made by the floodplain administrator in the enforcement or administration of this
article, other than that set forth in § 7-333 may be appealed to the construction and fire prevention
board of appeals.
(1) An appeal of an interpretation must be in writing and filed with the flood administrator and
appeal board and specifically allege the error in the decision or determination of the floodplain
Chapter 7, Article VIII Ordinance No.
Page 16 of 30
administrator for the property in question. All such appeals to the appeal board must be made 30
days from the date of the floodplain administrator's official written decision or determination.
(2) Applicants shall provide any additional information upon request of the appeal board that is
deemed necessary to review the request for variance.

Page 20 of 30
(c) Base flood elevation data for FEMA regulatory and fully developed conditions shall be
generated for subdivision proposals and other proposed development, including the placement of
manufactured home parks, and subdivisions which are greater than 1 acre, if not otherwise
provided pursuant to this article.
(d) All subdivision proposals including manufactured home parks and subdivisions shall have
adequate drainage provided to reduce exposure to flood hazards.
(e) All subdivision proposals including manufactured home parks and subdivisions shall have
public utilities and facilities such as sewer, gas, electrical and water systems located and
constructed to minimize or eliminate flood damage.
(f) Base flood elevation data shall be generated by a detailed engineering study for all Zone A
areas, within 100 feet of the contour lines of Zone A areas, and other streams not mapped by
FEMA, as indicated on the community's FIRM.
(g) FEMA floodplains and the City's fully developed floodplains must be mapped anywhere that
the contributing drainage area is 64 acres or greater. Post -project FEMA floodplain delineations
must be submitted to FEMA through the Letter of Map Change (LOMC) process, and compliant
with all applicable Federal regulations. FEMA floodplains must be based upon either the FEMA
current effective hydrologic model for the basin, or a new hydrologic model that reflects existing
land uses with the proposed project in place. The City's fully developed floodplains must be based
upon fully developed basin conditions from either a hydrologic model previously accepted by the
City, or from a new hydrologic model compliant with criteria in the most current Stormwater
Criteria Manual.
(h) Existing channels must not be increased or decreased from their natural state until engineering
data meeting the requirements of Stormwater Management has been approved.
(i) When development is proposed in areas that do not indicate an established floodway (Zones
A and AE), a licensed professional engineer shall define the regulatory floodway through
hydrologic and hydraulic analyses. The Floodplain Administrator can make the determination to
not require establishment of a floodway for sites where it might not be possible to designate a
typical one foot flood rise floodway using the standard FEMA approved models or where one
would make little practical sense.
0) If building permits are requested for the individual lots which are shown located within the
effective FEMA floodplain (not including floodway) before the LOMR to revise the FEMA
floodplain to reflect the subdivision has become effective then separate Floodplain Development
Permits will be required for each lot. For lots located within the effective FEMA floodway, FDPs
cannot be issued until the LOMR to revise the floodway has become effective. As a condition of
approval for the FDPs, an elevation certificate for the individual lot must be submitted to the city
within 60 days upon completion of construction. In addition, the following conditions must be
met to obtain approval of the permit:
(1) Either, the LOMR flood study must be reviewed and approved by the City and submitted to
FEMA for review with the FEMA case number provided to the City; or,
(2) A preconstruction elevation certificate for the individual lot must be provided to verify the
grading matches the approved plans and to confirm the structure will be built to the correct
minimum finished floor elevation.
Chapter 7, Article VIII Ordinance No.
Page 21 of 30
Sec. 7-349 STANDARDS FOR AREAS OF SHALLOW FLOODING (AO/AH ZONES).
Areas of shallow flooding are designated as AO or AH Zones within areas of special flood hazard.
These shallow flooding areas have special flood hazards with base flood depths of one (1) to three
(3) feet where a clearly defined channel does not exist and where the path of flooding is
unpredictable and indeterminate, and where velocity flow may be evident. Such flooding is
characterized by pond or sheet flow; therefore, in these areas the following provisions shall apply:
(a) All new construction and substantial improvements of residential structures must have the
lowest floor (including basement, finished garage, and machinery or equipment servicing the
building) elevated two feet above the fully developed base flood elevation or the FEMA regulatory
base flood elevation, or two feet above the highest adjacent grade, or two feet above the depth
number specified in feet on the FIRM (at least two feet if no depth number is specified), whichever
is higher controls.
(b) All new construction and substantial improvement of nonresidential structures shall comply
with either (b)(1) or (b)(2) below.
(1) The lowest floor (including basement, finished garage, and machinery or equipment
servicing the building) must be elevated two feet above the fully developed base flood elevation or
the FEMA regulatory base flood elevation, or two feet above the highest adjacent grade at least as
high as the depth number specified in feet on the FIRM (at least two feet if no depth number is
specified), whichever is higher controls; or
(2) The structure and attendant utility and sanitary facilities must be floodproofed to or above
the controlling elevation described in subsection (b)(1) above, so that below the base specified
flood depth in an AO Zone, or below the base blood elevation in an AH Zone, and any space below
that elevation is -watertight with walls substantially impermeable to the passage of water and with
structural components having the capability of resisting hydrostatic and hydrodynamic loads and
effects of buoyancy.
(c) A registered professional engineer, or architect, as applicable, shall submit a certification to
the floodplain administrator that the standards of this article are satisfied.
(d) Adequate drainage paths shall be provided around structures on slopes within Zones AH or
AO to guide flood waters around and away from proposed structures.
Floodways are areas located within areas of special flood hazard. The floodway can be an
extremely hazardous area due to the velocity of flood waters which can carry debris, potential
projectiles and erosion concerns. Therefore, the following provisions shall apply:
(a) Encroachments are prohibited, including fill, new construction, substantial improvements of
non -conforming structures, and other development within the adopted regulatory floodway unless
it has been demonstrated to the satisfaction of the floodplain administrator by a professional
registered engineer through hydrologic and hydraulic analyses performed in accordance with
standard engineering practice that the encroachment, individually or collectively, shall not result
in any increase in flood flows or damages and shall not increase the base flood elevation during
the occurrence of the 1 % annual chance storm event for fully developed conditions. The registered
Chapter 7, Article VIII Ordinance No.
Page 22 of 30
professional engineer must submit a no -rise certificate with supporting documentation to the
floodplain administrator if a no -rise analysis is completed.
(b) If the provisions of the foregoing subsection (a) are satisfied, all new construction and
substantial improvements shall comply with all applicable flood hazard reduction provisions of
this article.
(c) Under the provisions of 44 C.F.R. Chapter 1, § 65.2, of the National Flood Insurance
Regulations, a community may permit encroachments within the adopted regulatory floodway that
would result in an increase in base flood elevations, provided that the community first completes
all of the provisions required by Section 65.12 of the National Flood Insurance Program
regulations.
(d) Exemptions for minor projects. Small projects that are not an obstruction to floodwaters, do
not increase the natural grade, and will not increase flood stages can be permitted without requiring
a no -rise certification per the discretion of the floodplain administrator. Minor project examples
include paving of a driveway or parking area at the existing grade, and small isolated obstructions
such as a mailbox, a pitcher's mound, or a single telephone pole.
(e) No person shall proceed with development of property within the floodway until a Floodplain
Development Permit has been issued and the development is in compliance with this section.
See. 7-351 PENALTIES FOR NONCOMPLIANCE.
No structure or land shall hereafter be constructed, located, extended, converted, altered or have
its use changed without full compliance with the terms of this article and other applicable
regulations. Violation of the provisions of this article by failure to comply with any of its
requirements (including violations of conditions and safeguards established in connection with
conditions) shall constitute a misdemeanor. Any person who violates this article or fails to comply
with any of its requirements shall, upon conviction thereof, be fined not more than $2,000 for each
violation in accordance with § 1-6(b), and each and every day the violation occurs shall constitute
a separate violation. Nothing herein contained in this section or any other section of this article
shall prevent the City of Fort Worth from taking such other lawful action as is necessary to prevent
or remedy any violation, including but not limited to refusal to approve a plat or to issue a building
permit, or to obtain injunctive relief against the violator pursuant to Tex. Local Government Code
§ 54.016 or any other statute, or any other legal remedy available to the city.

or other situation posing a serious threat to the public health, safety or welfare.

permitting decisions within our jurisdiction while allowing our neighboring communities and
agencies the opportunity to review and comment on projects along the Trinity River Corridor.

area. The CDC Model includes constructed projects and several projects that are permitted but no
constructed.
CORRIDOR DEVELOPMENT CERTIFICATE (CDC). Permission for development
activity within the Regulatory Zone of the Trinity River Corridor. The CDC is issued by the city as
part of the floodplain permitting process prior to development.
CORRIDOR DEVELOPMENT CERTIFICATE MANUAL (CDC MANUAL).

the CDC application.
DEVELOPMENT. Any human -made change to improved or unimproved real estate, including
but not limited to, the construction or alteration of buildings or other structures, mining, dredging,

project may be judged and compared with protection provided for similar projects in other
localities. In general terms, the SPF for the Trinity River Corridor is commonly equated to an 800-
year storm frequency.
