OLLEYVILLE CODE BY MODIFYING THE REGULATIONS PERTAINING TO THE
5 ONTROL AND CONSTRUCTION WITHIN THE FLOOD HAZARD AREAS OF THE
ITY.

WHEREAS, the City Council deems it is in the best
interest of the City to modify its flood area
hazard regulation as provided herein,
7
8 OW, THEREFORE, BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF
OLLEYVILLE, TEXAS:
9
FLOOD HAZARD AREA REGULATIONS
"SECTION 9:
10
A. STATUTORY AUTHORIZATION
11
The Legislature of the State of Texas has by the
statutes delegated the responsibility to local
governmental units to adopt regulations designed to
minimize flood losses. Therefore, the City Council of
the City of Colleyville, Texas does ordain as follows:
12
13
B.
FINDING OF FACT
14
(1) The flood hazard areas of the City of Colleyville
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.
15
16
17
18
(2) These flood losses are created by the cumulative
effect of obstructions in flood plains 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, flood-
proofed, or otherwise protected from flood damage.

conditions in specific areas by Vrovisions designed to:
(1) To protect human life and health;
(2) To minimize expenditure of public money for costly
flood control proJects;
(3) To minimize the need for rescue and relief efforts
associated with flooding and generally undertaken
at the expense of the general public;
(4) To minimize prolonged business interruptions;
(5) To minimize damage to public facilities and
utilities such as water and gas mains, electric,
telephone and sewer lines, streets and bridges
located in flood plains;
(6) To 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) To insure the potential buyers are notified that
property is in a flood area.
D. METHODS OF REDUCING FLOOD LOSSES
In order to accomplish its purposes, this ordinance uses
the following methods:
(1) Restrict or prohibit uses that are dangerous to
health, safety or property in times of flood, or
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 flood plains,
stream channels, and natural protective barriers,
which are involved in the accomodation of flood
waters;
(4) Control filling, grading, dredging and other
development which may increase flood damage;

E. DEFINITIONS
Unless specifically defined below, words or phrases
used in this ordinance shall be interpreted to give
them the meaning they have in common usage and to give
this ordinance its most reasonable application.
(1) Apeeal means a request for a review of the city
manager's interpretation of any provisions of this
ordinance or a request for a variance.
(2) Area of Shallow Flooding means a designated AO,
AH, or VO Zone on a community's Flood Insurance
Rate Map (FIRM) with a one percent or greater
chance of flooding to an average depth of one to
three feet where a clearly defined channel does
not exist, where the path of flooding is
unpredictable and where velocity flow may be
evident. Such Flooding is characterized by
ponding or sheet flow.
(3) Area of Specia~-'lg~~ Hazard is the land in the
flood plain within a community subject to a one
percent or greater chance of flooding in any given
year. The area may be designated as Zone A on the
FHBM. After detailed ratemaking has been
completed in preparation for publication of the
FIRM, Zone A usually is refined into Zones A, AO,
AH, Al-9, VO, or Vl-30.
(4) Base Flood means the flood having a one percent
chance of being equalled or exceeded in any given
year.
(5) DeveJ~~men~ means any man-made change to improved
or unimproved real estate, including but not
limited to, buildings or other structures, mining,
dredging, filling, grading, paving, excavation or
drilling operations.

providing the relevant factors in subsection 0(2)
of this section have been fully considered. As
the lot size increases beyond the one-half acre,
the technical justification required for issuing
the variance increases.
(7) Upon consideration of the factors noted above and
the intent of this ordinance, the Zoning Board of
Adjustment may attach such conditions to the
granting of variances as it deems necessary to
further the purpose and objectives of subsections
C and D of this section.
(8) Variances shall not be issued within any
designated floodway if any increase in flood
levels during the base flood discharge would
resul t.
(9) Prerequisites for granting variances:
(a) Variances shall only be issued upon a
determination that the variance is the
minimum necessary, considering the flood
hazard, to afford relief.
(b) Variances shall only be issued upon (1) a
showing of good and sufficient cause, (2) a
determination that failure to grant the
variance would result in exceptional hardship
to the applicant, and (3) 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.
(c) Any applicant to whom a variance is granted
shall be given written notice that the
structure will be permitted to be built with
a lowest floor elevation no more than 3 feet
below the base flood elevation, and that the
cost of flood insurance will be commensurate
with the increased risk resulting from the
reduced lowest floor elevation.

(6') above the ground level.
(iii) All new manufactured homes to be placed
or substantially improved within zones
Ai-3D, AH, AE and all new mobile home
parks and subdivisions; for expansions
to existing mobile home parks and
subdivisions; for existing mobile home
parks and subdivisions where the repair,
reconstruction or improvement of the
streets, utilities and pads equals or
exceeds 50 percent of value of the
streets, utilities and pads before the
repair, reconstruction or improvement
has commenced; and for mobile homes not
placed in a mobile home park or
subdivision require:
* stands or lots are elevated on compacted
fill or on pilings so that the lowest
floor of the mobile home will be at or
above the base flood level. A
registered professional engineer,
architect, or land surveyor shall submit
a certification to the city manager that
the standard of this paragraph complies
with subsection Q(2)(a) of this section.
* adequate surface drainage and access for
a hauler are provided; and,
* in the instance of elevation on pilings:
(1) lots are large enough to permit
steps, (2) piling foundations are placed
in stable soil no more than ten feet
apart, and (3) reinforcement is provided
for pilings more than six feet above the
ground level.
(d) Floodways - located within areas of special
flood hazard established in subsection G,
are areas designated as floodways.
Since the floodway is an extremely hazardous
area due to the velocity of flood waters
which carry debris, potential projectiles and
erosion potential, the following provisions
shall apply:

(i) Encroachments are prohibited, including
fill, new construction, substantial
improvements and other developments
unless certification by a professional
registered engineer or architect is
provided demonstrating that
encroachments shall not result in any
increase in flood levels during
occurence of the base flood discharge.
(ii) If subsection Q (2)(d)(i) above is
satisfied, all new construction and
substantial improvements shall comply
with all applicable flood hazard
reduction provisions of subsection Q.
(iii) Prohibit the placement of any mobile
homes, except in an existing mobile home
park or subdivision.
(3) STANDARDS FOR AREAS OF SHALLOW FLOODING
(AO ZONES)
Located within the areas of special flood hazard
established in subsection G are areas designated
as shallow flooding. These areas have special
flood hazards associated with base flood depths of
1 to 3 feet where a clearly defined channel does
not exist and where the path of flooding is
unpredictable and indeterminate; therefore, the
following provisions apply:
(a) All new construction and substantial
improvements of residential structures 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 community's FIRM (at least two
feet if no depth number is specified).
(b) All new construction and substantial
improvements of nonresidential structures:
(i) 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
community's FIRM (at least two feet if

no depth number is specified), or;
(ii) together with attendant utility and
sanitary facilities be designated 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.
(c) A registered professional engineer or
architect shall submit a certification to the
city manager the standards of this Section,
as proposed in subsec tion O( 1) (a) are
satisfied.
(d) Require within Zones AH and AO, adequate
drainage paths around structures on slopes,
to guide floodwaters around and away from
proposed structures.
(4) STANDARDS FOR SUBDIVISION PROPOSALS
(a) All subdivision proposals shall be consistent
with Article I, Sections B, C and D of this
ordinance.
(b) All proposals for the development of
subdivisions shall meet Development Permit
requirements of subsection H, subsection 0,
and subsection Q of this section.
(c) Base flood elevation data shall be provided
for subdivision proposals and other proposed
development which is greater than the lesser
of 50 lots or 5 acres, if not otherwise
provided pursuant to subsection G or
subsection N(7) of this section.
(d) All subdivision proposals shall have adequate
drainage provided to reduce exposure to flood
hazards.
(e) All subdivision proposals shall have public
utilities and facilities such as sewer, gas,
electrical and water systems located and

constructed to minimize flood damage.
(5) Standards for area within Vl-30, VE and V Zones
All new construction and substantial improvement
in Zones VI-3D and VE, and also Zone V, if base
flood elevation data are available on the
community's FIRM, are elevated on pilings and
columns so that (i) the bottom of the lowest
horizontal structural member of the lowest floor
(excluding the pilings or columns) is elevated to
or above the base flood level; and (ii) 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. Wind and water loading
values shall each have a one percent chance of
being equalled or exceeded in any given year (100-
year mean recurrence interval). 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 and
practice for meeting the provisions of (i) and
(ii) of this paragraph.
(6) Placement of Mechanical and Utility Equipment
All electrial, heating, ventilation, plumbing, and
air-conditioning equipment and other service
facilities shall be designed and/or located so as
to prevent water from entering or accumulating
within the components during conditions of
flooding."
