Start of construction (for other than new construction or substantial improvements under
the Coastal Barrier Resources Act (Pub. L. 97-348)), includes substantial improvement, and means
the date the building permit was issued, provided the actual start of construction, repair,
reconstruction, rehabilitation, addition placement, or other improvement was within 180 days of
the permit date. The actual start means either the first placement of permanent construction of a
structure on a site, such as the pouring of slab or footings, the installation of piles, the construction

home on a foundation. Permanent construction does not include land preparation, such as clearing,
grading and filling; nor does it include the installation of streets and/or walkways; nor does it
include excavation for a basement, footings, piers, or foundations or the erection of temporary
forms; nor does it include the installation on the property of accessory buildings, such as garages
or sheds not occupied as dwelling units or not part of the main structure. For a substantial
improvement, the actual start of construction means the first alteration of any wall, ceiling, floor,
or other structural part of a building, whether or not that alteration affects the external dimensions
of the building.
Structure or building means:
(a) for floodplain management purposes, a walled and roofed building, including a gas
or liquid storage tank, that is principally aboveground, as well as a manufactured
home; and
(b) for insurance purposes:

of restoring the structure to its before -damaged condition would equal or exceed 50 percent of the
market value of the structure before the damage occurred.
Substantial improvement means any reconstruction, rehabilitation, addition, or other
improvement of a building, the cost of which equals or exceeds 50 percent of the market value of
the building before the "start of construction" of the improvement. The term includes buildings
that have incurred "substantial damage," regardless of the actual repair work performed. The term
does not, however, include either:
(a) any project for improvement of a building to correct existing violations of state or
local health, sanitary, or safety code specifications which have been identified by
37
the local code enforcement official and which are the minimum necessary to assure
safe living conditions; or
(b) any alteration of a "historic building," provided that the alteration will not preclude
the building's continued designation as a "historic building."

Part 60, Subpart A, §§ 60.3(b)(5), (c)(4), (c)(10), (d)(3), (e)(2), (e)(4), or (e)(5) is presumed to be
in violation until such time as that documentation is provided.
Water surface elevation means the height, in relation to the National Geodetic Vertical
Datum (NGVD) of 1929 (or other datum, where specified) of floods or various magnitudes and
frequencies in the flood plains of coastal or riverine areas.
Sec. 110-27. Statutory authorization.
The state legislature has in the Flood Control Insurance Act, V.T.C.A. Water Code
§ 16.315, delegated the responsibility of the local governmental units to adopt regulations designed
to minimize flood losses. Therefore, the city council of the city does hereby ordain the regulations
in this chapter.
Sec. 110-28. Findings of fact.
(a) The moderate and special flood hazard areas of the city 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
38
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. 110-29. 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 provisions
designed to:
(1) Protect human life and health;
(2) Minimize expenditure of public money for costly flood control projects;
(3) Minimize the need for rescue and relief efforts associated with flooding and
generally undertaken at the expense of the general public;
(4) Minimize prolonged business interruptions;
(5) Minimize damage to public facilities and utilities such as water and gas mains,
electric, telephone and sewer lines, streets and bridges located in floodplains;
(6) 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 future flood blight areas; and
(7) Ensure that potential buyers are notified that property is in a flood area.
Sec. 110-30. Methods of reducing flood losses.
In order to accomplish its purposes, this chapter uses the following methods:
(1) Restrict or prohibit uses that are dangerous to health, safety or property in the times
of flood or that cause excessive increases in flood heights or velocities;
(2) Require that uses vulnerable to floods, including facilities which serve such uses,
be protected against flood damage at the time of initial construction;
(3) Control the alteration of natural floodplains, stream channels and natural protective
barriers, which are involved in the accommodation of floodwaters;
(4) Control filling, grading, dredging and other development which may increase flood
damage; and
(5) Prevent or regulate the construction of flood barriers which will unnaturally divert
floodwaters or which may increase flood hazards to other lands.
39
Sec. 110-31. Lands to which article applies.
This article shall apply to all moderate and special flood hazard areas within the jurisdiction
of the city.
Sec. 110-32. Basis for establishing the moderate and special flood hazard areas.
The moderate and special flood hazard areas as identified by FEMA in the scientific and
engineering reports entitled, "The Flood Insurance Study for I iarris County, Texas" effective June
18, 2007, including any FEMA-issued preliminary maps, and "The Flood Insurance Study for
Chambers County, Texas" dated May 4, 2015, with accompanying flood insurance rate maps and
all subsequent amendments and/or revisions thereto are hereby adopted by reference and declared
to be a part of this article. Such maps are available for review in the office of the floodplain
administrator. Original copies of the official maps and all amendments thereto shall be maintained
in the office of the floodplain administrator. In any dispute regarding the maps, the original map
maintained at the office of the floodplain administrator shall control.
Sec. 110-33. Compliance.
No structure or land located within an area of moderate or special flood hazard shall be
built, constructed, renovated, altered, cleared, filled, excavated or have its use changed without
full compliance with the terms of this article and other applicable regulations. Violation of the
provisions of this chapter by failure to comply with any of its requirements shall constitute a
misdemeanor, punishable by penalties as provided in section 1-14. Nothing herein contained shall
prevent the city from taking such other lawful action as is necessary to prevent or remedy any
violation.
Sec. 110-34. Abrogation and greater restrictions.
This article is not intended to repeal, abrogate or impair any existing easements, covenants
or deed restrictions. However, where the requirements of this article and another ordinance,
easement, covenant or deed restriction conflict or overlap, whichever imposes the more stringent
restrictions shall prevail.
Sec. 110-35. Interpretation.
In the interpretation and application of this article, all provisions shall be:
(1) Considered as minimum requirements;
40
(2) Liberally construed in favor of the city council; and
(3) Deemed neither to limit nor repeal any other powers granted under state statutes.
Sec. 110-36. Warning and disclaimer of liability.
The degree of flood protection required by this article is considered reasonable for
regulatory purposes and is based on scientific and engineering considerations. On rare occasions,
greater floods can and will occur and flood heights may be increased by manmade or natural
causes. This article does not imply that land outside the moderate and special flood hazard areas
or uses permitted within such areas will be free from flooding or flood damages. This article shall
not create liability on the part of the city or any officer or employee thereof for any flood damages
that result from reliance on this article or any administrative decision lawfully made under this
article.

(c) 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.
(d) 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, providing the relevant factors in
subsection 110-69(b) have been fully considered. As the lot size increases beyond one-half
acre, the technical justification required for issuing the variance increases.
(e) Upon consideration of the factors noted in this subsection and the intent of this article, the
city council may attach such conditions to the granting of variances as it deems necessary
to further the purpose and objectives of this article as stated in section 110-29.
(f) Variances shall not be issued within any designated floodway if any increase in flood levels
during the base flood discharge would result.
(g) Variances may be issued for the repair or rehabilitation of historic structures upon a
determination that the proposed repair or rehabilitation will not preclude the structure's
continued designation as a historic structure and the variance is the minimum necessary to
preserve the historic character and design of the structure.
(h) Prerequisites for granting variances shall be as follows:
(1) Variances shall only be issued after a written a written request therefor and upon a
determination that the variance is the minimum necessary, considering the flood
hazard, to afford relief.
(2) Variances shall only be issued upon:
a. A showing of good and sufficient cause;
45
b. A determination that failure to grant the variance would result in exceptional
hardship to the applicant; and
C. A determination that the granting of a variance will not result in increased
flood heights, additional threats to public safety, extraordinary public
expense, create nuisances, cause fraud on or victimization of the public or
conflict with existing local laws or ordinances.
(3) Any applicant who applies for a variance from this article shall be given written
notice that the issuance of a variance to construct a structure below the base flood
level will result in increased premium rates for flood insurance up to amounts as
high as $25 for $100 of insurance coverage and such construction below the base
flood level increases risks to life and property.
(i) Variances may be issued by the city for new construction, for substantial improvements
and for other development necessary for the conduct of a functionally dependent use
provided that:
(1) The criteria outlined in this subsection are met; and
(2) 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.
See. 110-71. Substantial damage/improvement.
(a) Determinations.
(1) The floodplain administrator shall make all determinations regarding substantial
damage to a structure within the special flood hazard areas. Should the structure be
determined to be substantially damaged, that structure shall be required to meet all
of the current pertinent requirements of this chapter.
The market value of the structure shall be the value determined by the
central appraisal district of the appropriate county.
b. The estimated amount of damage shall be calculated by dividing the
estimated cost to repair the structure to its pre -damaged condition by the
market value of the structure.
C. If a structure was determined to be damaged less than 50 percent of its pre -
damage market value but the actual value of the repairs exceed 50 percent
of the pre -damage market value, the structure will fall under the category of
substantially improved and will be required to meet all of the current
pertinent requirements of this chapter.
46
(2) The floodplain administrator shall make all determinations regarding substantial
improvement to a structure within the special flood hazard areas. Should the
proposed improvements be determined to be a substantial improvement, the
existing structure and the proposed improvements to the structure shall be required
to come into conformance and or meet the current pertinent requirements of this
chapter.
a. The market value of the structure shall be the value determined by the
central appraisal district of the appropriate county.
b. The estimated percentage of improvement shall be calculated by dividing
the estimated cost of the improvement by the value of the structure prior to
improvement.
(b) Appeals.
(1) An applicant for a floodplain development permit may appeal the determination of
substantial damage and/or substantial improvement.
(2) A determination appeal may be based upon the following:
a. The determination was made without sufficient information;
b. There was a mathematical or technical error made in the determination;
C. The estimate of repair costs was incorrect;
d. The estimated value of improvements was incorrect; or
e. The estimated market value of the structure was incorrect.
(3) The applicant shall apply for the appeal using a form to be provided by the
floodplain administrator.
(4) The appellant applicant shall submit documentation supporting the claim for
appeal. The documentation may include:
a. Any information that was lacking or missing during the initial
determination;
b. Proof of a mathematical or technical error in the determination;
C. Actual repair or construction estimates from established contractors that are
permitted to perform work in the city;
d. If the basis of the appeal is the market value of the structure, the appellant
shall provide an appraisal report that is signed or endorsed by an actively
47
licensed residential appraiser, certified residential appraiser, or a certified
general appraiser who is in good standing with the state appraiser licensing
and certification board.

Sec. 110-104. Standards for areas of shallow flooding (AO/AH zones).
Located within the areas of special flood hazard established in section 110-32 are areas
designated as shallow flooding. These areas have special flood hazards associated with base flood
depths of one to three feet where a clearly defined channel does not exist and where the path of
flooding is unpredictable and where velocity flow may be evident. Such flooding is characterized
by ponding or sheet flow; therefore, the following shall apply:
(1) Residential structures. All new construction and substantial improvements of
residential structures shall have the lowest floor, including basement, and all
components of the electrical and mechanical systems or any other service facility
elevated above the highest adjacent grade at least one foot higher than the depth
number specified in feet on the community's FIRM (at least two feet if no depth
number is specified). Additionally, plumbing systems shall be designed and'or
located so as to prevent floodwaters from entering or damaging them.
(2) Nonresidential structures. All new construction and substantial improvements shall:
a. Have the lowest floor, including basement, and all components of the
electrical and mechanical systems or any other service facility elevated
above the highest adjacent grade at least one foot higher than the depth
number specified in feet on the community's FIRM (at least two feet if no
depth number is specified); or
b. Together with attendant utility and sanitary facilities, be designed so that
below the base flood level, the structure is watertight with walls
substantially impermeable to the passage of water and with structural
components having the capability of resisting hydrostatic and
hydrodynamic loads or effects of buoyancy. Additionally, plumbing
systems shall be designed and/or located so as to prevent floodwaters from
entering or damaging them.
56
(3) A registered professional engineer shall submit a certification to the floodplain
administrator that the standards of this section, as proposed in subsection 110-69,
have been satisfied.

structures shall be required.
Sec. 110-105. Standards for regulatory floodways.
Located within areas of special flood hazard established in section 110-32 are areas
designated as regulatory floodways. Since the regulatory floodway is an extremely hazardous area
due to the velocity of floodwaters which carry debris, potential projectiles and erosion potential,
the following shall apply:
(1) Encroachments are prohibited, including fill, new construction, substantial
improvements and other development within the adopted regulatory floodway,
unless it has been demonstrated through hydrologic and hydraulic analysis
performed in accordance with standard engineering practice that the proposed
encroachments shall not result in any increase in flood levels within the community
during the occurrence of the base flood discharge.
(2) If subsection (1) of this section is satisfied, all new construction and substantial
improvements shall comply with all applicable flood hazard reduction provisions
of this chapter.
(3) Under the provisions of 44 C.F.R. §65.12 of the National Flood Insurance Program
regulations, the city may permit encroachments within the adopted regulatory
floodway that would result in an increase in base flood elevations, provided the city
first applies for a conditional FIRM and floodway revision through FEMA.
Sec. 110-106. Standards for coastal high hazard areas.
Located within the special flood hazard areas established in section 110-32 are areas
designated as coastal high hazard areas (zone V 1-30, VE and/or V). These areas have special flood
hazards associated with high velocity waters from tidal surges and hurricane wave wash; therefore,
the design and construction of projects located within an area of coastal high hazard shall, at a
minimum, meet the following requirements:
(1) All new construction shall be located landward of the reach of mean high tide;
(2) All new construction, substantial improvements shall be elevated on pilings and
columns so that:
57
a. The bottom of the lowest horizontal structural member of the lowest floor,
excluding the pilings or columns, is elevated 24 inches above the base flood
level;
b. The pile or column foundation and structure attached thereto is anchored to
resist flotation, collapse and lateral movement due to the effects of wind and
water loads acting simultaneously on all building components. Water
loading values used shall be those required by applicable state or local
building standards; and
C. A registered professional engineer shall develop or review the structural
design, specifications and plans for the construction.
(3) Provide that all new construction and substantial improvements have the space
below the lowest floor either free of obstruction or constructed with non -supporting
open wood latticework or insect screening intended to collapse under wind and
water loads without causing collapse, displacement or other structural damage to
the elevated portion of the building or supporting foundation system. Breakaway
walls are prohibited within coastal high hazard areas.
(4) The use of fill for structural support of buildings is prohibited;
(5) Manmade alteration of sand dunes and mangrove stands which increase potential
flood damage is prohibited;
(6) All manufactured homes placed or substantially improved shall meet the standards
of subsections (a) through (e) of this section and subsection 110-102(4).
(7) All recreational vehicles must:
a. Be on the site for fewer than 180 consecutive days;
b. Be fully licensed and ready for highway use; or
C. Be elevated on a permanent foundation such that the chassis is elevated to
or above the base flood elevation and be securely anchored to an adequately
anchored foundation system to resist floatation collapse and lateral
movements.
