The legislature of the state has in the Flood Control Insurance
Act, Texas Water Code, section 16.315, delegated the responsibility
of local governmental units to adopt regulations designed to minimize
flood losses. Therefore, the city does ordain as follows.
(Ordinance 13-0211-03, art. 1, sec.
A, adopted 2/11/13)
(a)
The
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 hazard areas by uses vulnerable to floods
and hazardous to other lands because they are inadequately elevated,
floodproofed or otherwise protected from flood damage.
(Ordinance 13-0211-03, art. 1, sec.
B, adopted 2/11/13)
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 floodprone 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.
(Ordinance 13-0211-03, art. 1, sec.
C, adopted 2/11/13)
In order to accomplish its purposes, this article 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 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;
(5)
Prevent
or regulate the construction of flood barriers which will unnaturally
divert floodwaters or which may increase flood hazards to other lands.
(Ordinance 13-0211-03, art. 1, sec.
D, adopted 2/11/13)

Those physical structural works for which funds have been
authorized, appropriated, and expended and which have been constructed
specifically to modify flooding in order to reduce the extent of the
area within a community subject to a “special flood hazard”
and the extent of the depths of associated flooding. Such a system
typically includes hurricane tidal barriers, dams, reservoirs, levees
or dikes. These specialized flood modifying works are those constructed
in conformance with sound engineering standards.
The operation of an overall program of corrective and preventive
measures for reducing flood damage, including but not limited to emergency
preparedness plans, flood-control works and floodplain management
regulations.
Zoning ordinances, subdivision regulations, building codes,

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

of a structure, the cost of which equals or exceeds 50 percent of
the market value of the structure before “start of construction”
of the improvement. This term includes structures, which have incurred
“substantial damage,” regardless of the actual repair
work performed. The term does not, however, include either:
Any project for improvement of a structure to correct existing
violations of state or local health, sanitary, or safety code specifications
which have been identified by the local code enforcement official
and which are the minimum necessary to assure safe living conditions;
or
Any alteration of a “historic structure,” provided
that the alteration will not preclude the structure’s continued
designation as a “historic structure.”
A grant of relief by a community from the terms of a floodplain
management regulation. (For full requirements see section 60.6 of
the National Flood Insurance Program regulations.)
The failure of a structure or other development to be fully
compliant with the community’s floodplain management regulations.
A structure or other development without the elevation certificate,
other certifications, or other evidence of compliance required in
section 60.3(b)(5), (c)(4), (c)(10), (d)(3), (e)(2), (e)(4), or (e)(5)
of the National Flood Insurance Program regulations is presumed to
be in violation until such time as that documentation is provided.
The height, in relation to the North American Vertical Datum
(NAVD) of 1988 (or other datum, where specified), of floods of various
magnitudes and frequencies in the floodplains of coastal or riverine
areas.
