HomeMy WebLinkAbout031740 ORD - 04/16/2019 Ordinance amending the Code of Ordinances, Chapter 14, Article V, Flood
Hazard Prevention Adopting Higher Standards; and providing for penalties
WHEREAS, the City can adopt higher floodplain management standards to promote increased
public health, safety, and general welfare by minimizing public and private losses due to flood
conditions in areas of special flood hazard.
WHEREAS, the City is a participant in a voluntary program of the National Flood Insurance
Program called the Community Rating System. This program provides points for going above
and beyond the minimum standards of a participating community.
WHEREAS, adopting higher standards provides additional points that can help to reduce flood
insurance premiums for flood insurance policies in a Special Flood Hazard Area.
Now therefore, be it ordained by the City Council of the City of Corpus Christi, Texas:
SECTION 1. That Corpus Christi Code of Ordinances, Chapter 14 "Development
Services", Article V"Flood Hazard Prevention Code," Section 14-552 "Specific standards"
is amended by adding the following language that is underlined (added) and deleting the
language that is stricken (deleted) as delineated below:
In all areas of special flood hazards where base flood elevation data has been provided as
set forth in section 14-522, section 14-532(8), or section 14-543(c), the following provisions are
required:
(1) Residential construction. New construction of any
residential structure must have the lowest floor(including basement), elevated to 1 (one)
foot at or above the base flood elevation. Substantial Damage and Substantial
Improvement must have the lowest floor (including basement), elevated to at or above
the base flood elevation. A registered professional engineer, architect, or land surveyor
shall submit a certification to the floodplain administrator that the standard of this
subsection as proposed in section 14-533(b)(1), is satisfied.
(2) Nonresidential construction. New construction of any
commercial, industrial, or other nonresidential structure must either have the lowest floor
(including basement) elevated to 1 (one)foot atm above the base flood level or 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 and effects of buoyancy. Substantial Damage and Substantial
Improvement must have the lowest floor (including basement), elevated to at or above
the base flood elevation or 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 and effects of
buoyancy. A registered professional engineer or architect shall develop and/or review
structural design, specifications, and plans for the construction, and shall certify that the
design and methods of construction are in accordance with accepted standards of
practice as outlined in this subsection. A record of such certification which includes the
031740

specific elevation (in relation to mean sea level) to which such structures are flood-
proofed shall be maintained by the floodplain administrator.
(4) Manufactured homes.
a. All manufactured homes to be placed within zone A on a city's FHBM or FIRM must
be installed using methods and practices which minimize flood damage.
1. For the purposes of this requirement, a manufactured home must be elevated
and anchored to resist flotation, collapse, or lateral movement.
2. Methods of anchoring may include, but are not limited to, use of over-the-top or
frame ties to ground anchors.
3. This requirement is in addition to applicable state and local anchoring
requirements for resisting wind forces.
b. Manufactured homes that are placed or substantially improved within zones A1-30,
AH, and AE on the city's FIRM must be on sites:
1. Outside of a manufactured home park or subdivision.
2. In a new manufactured home park or subdivision.
3. In an expansion to an existing manufactured home park or subdivision on which
a manufactured home has incurred substantial damage as a result of a flood,
be elevated on a permanent foundation such that the lowest floor of the
manufactured home is elevated to 1 (one) foot at or above the base flood
elevation and be securely anchored to an adequately anchored foundation
system to resist flotation, collapse, and lateral movement.
c. Manufactured homes must be placed on substantially improved on sites in an
existing manufactured home park or subdivision with zones A1-30, AH, and AE on
the city's FIRM that are not subject to the provisions of paragraph (4) of this
subsection must be elevated so that either:
1. The lowest floor of the manufactured home is 1 (one)foot at-Er above the base
flood elevation, or
2. The manufactured home chassis is supported by reinforced piers or other
foundation elements of at least equivalent strength that are no less than thirty-
six (36) inches in height above grade and be securely anchored to an
adequately anchored foundation system to resist flotation, collapse, and lateral
movement.
SECTION 2. That Corpus Christi Code of Ordinances, Chapter 14 "Development
Services", Article V"Flood Hazard Prevention Code," Section 14-554 "Standards for areas
of shallow flooding (AO/AH zones)" is amended by adding the following language that is
underlined (added) and deleting the language that is stricken (deleted) as delineated
below:
Locations within the areas of special flood hazard established in section 14-522 are
designated as shallow flooding areas. These areas have special flood hazards associated with
base flood depths of one (1) to three (3) feet, where a clearly defined channel does not exist and
Page 2
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 provisions apply:
(1) All new construction, of residential structures must have
the lowest floor(including basement) elevated above the highest adjacent grade at least
as high as the depth number specified in feet on the city's FIRM (at least two (2) feet if
no depth number is specified) plus 1 (one) foot. Substantial Damage and Substantial
Improvement must have the lowest floor (including basement), elevated to at or above
the highest adjacent grade at least as high as the depth number specified in feet on the
city's FIRM (at least two (2) feet if no depth number is specified).
(2) All new construction of nonresidential structures:
a. Must have the lowest floor (including basement) elevated above the highest
adjacent grade at least as high as the depth number specified in feet on the city's
FIRM (at least two (2)) feet plus 1 (one) foot, if no depth number is specified; or
b. Substantial Damage and Substantial Improvements must have the lowest floor
(including basement) elevated above the highest adjacent grade at least as high as
the depth number specified in feet on the city's FIRM (at least two (2)) feet, if no
depth number is specified; or
cb. Together with attendant utility and sanitary facilities must 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 of effects of buoyancy.
(3) A registered professional engineer or architect shall submit a certification to the
floodplain administrator that the standards of this section, as proposed in section 14-
533(b)(1), are satisfied.
(4) Structures within zones AH or AO must have adequate drainage paths around structures
on slopes, to guide floodwaters around and away from proposed structures.
SECTION 3. That Corpus Christi Code of Ordinances, Chapter 14 "Development
Services", Article V"Flood Hazard Prevention Code," Section 14-556"Coastal high hazard
areas" is amended by adding the following language that is underlined (added) and
deleting the language that is stricken (deleted) as delineated below:
(b) These areas have special flood hazards associated with high-velocity waters from tidal
surges and hurricane wave wash; therefore, in addition to meeting all provisions outlined in
this Code, the following provisions also apply:
(1) Obtain the elevation (in relation to mean sea level) of the bottom of the lowest structural
member of the lowest floor (excluding pilings and columns) of all new and substantially
improved structures, and whether or not such structures contain a basement. The
floodplain administrator maintains a record of all this information.
(2) All new construction must be located landward of the reach of mean high tide.
(3) All new construction and substantial damageimprovement& must be elevated on pilings
and columns so that:
a. The bottom of the lowest horizontal structural member of the lowest floor(excluding
the pilings or columns) is elevated to 1 (one) foot at—Of above the base flood
elevationlevel.
Page 3
b. Substantial Improvements must have the bottom of the lowest horizontal structural
member of the lowest floor(excluding the pilings or columns)elevated to at or above
the base flood elevation.
cb. The pile or column foundation and structure attached to the foundation is anchored
to resist flotation, collapse, and lateral movement due to the effects of wind and
water loads acting simultaneously on all building components.
1. Water loading values used must be those associated with the base flood.
2. Wind loading values used shall be those required by applicable state or local
building standards.
(4) A registered professional engineer or architect shall develop or review the structural
design, specifications and plans for the construction, and shall certify that the design and
methods of construction to be used are in accordance with accepted standards of
practice for meeting the provisions of paragraph (3)(a) and (b) of this subsection.
(5) All new construction and substantial improvements must have the space below the
lowest floor either free of obstruction or constructed with non-supporting breakaway
walls, open wood lattice-work, 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.
(6) For the purpose of this section, a breakaway wall shall have a design safe loading
resistance of not less than ten (10), and not more than twenty (20) pounds per square
foot.
(7) Use of breakaway walls, which exceed a design safe loading resistance of twenty (20)
pounds per square foot (either by design or when so required by local or state codes),
may be permitted only if a registered professional engineer or architect certifies that the
designs proposed meet the following conditions:
a. Breakaway wall collapse must result from a water load less than that which would
occur during the base flood; and
b. The elevated portion of the building and supporting foundation system may not be
subject to collapse, displacement, or other structural damage due to the effects of
wind and water loads acting simultaneously on all building components (structural
and nonstructural).
1. Water loading values used shall be those associated with the base flood.
2. Wind loading values used shall be those required by applicable state or local
building standards.
(8) Enclosed space below the lowest floor may be useable solely for parking of vehicles,
building access, or storage. The enclosed space below the lowest floor may not be used
for human habitation.
a. All enclosed areas below base flood elevation that are greater than 5 (five) feet In
height will be required to sign a non-conversion agreement that will be filed with the
deed.
(9) The use of fill or structural support of buildings is prohibited.
Page 4
(10)The use of manmade alteration of sand dunes and mangrove stands, which would
increase potential flood damage, is prohibited.
(11)Manufactured homes, which have incurred substantial damage as the result of a flood,
must meet the standards of paragraphs (1) through (10) of this subsection, if they are
placed or substantially improved within zones V1-30, V, and VE on the city's FIRM on
sites:
a. Outside of a manufactured home park or subdivision,
b. In a new manufactured home park or subdivision,
c. In an expansion to an existing manufactured home park or subdivision, or
(12)Manufactured homes placed or substantially improved on other sites in an existing
manufactured home park or subdivision within zones V1-30, V, and VE on the city's FIRM
meet the requirements of section 14-542(4) of this Code.
