The city administrator or designee is hereby appointed the floodplain
administrator to administer and implement the provisions of this article
and other appropriate sections of 44 CFR (Emergency Management and
Assistance - National Flood Insurance Program regulations) pertaining
to floodplain management.
(Ordinance adopted 1/12/10)
Duties and responsibilities of the floodplain administrator
shall include, but not be limited to, the following:
(1)
Maintain
and hold open for public inspection all records pertaining to the
provisions of this article.
(2)
Review
permit application to determine whether to ensure that the proposed
building site project, including the placement of manufactured homes,
will be reasonably safe from flooding.
(3)
Review,
approve or deny all applications for development permits required
by adoption of this article.
(4)
Review
permits for proposed development to assure that all necessary permits
have been obtained from those federal, state or local governmental
agencies (including section 404 of the Federal Water Pollution Control
Act Amendments of 1972, 33 USC 1334) from which prior approval is
required.
(5)
Where
interpretation is needed as to 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.
(6)
Notify,
in riverine situations, adjacent communities and the state coordinating
agency which is 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.
(7)
Assure
that the flood carrying capacity within the altered or relocated portion
of any watercourse is maintained.
(8)
When base flood elevation data has not been provided in accordance with section 3.06.006, the floodplain administrator shall obtain, review and reasonably utilize any base flood elevation data and floodway data available from a federal, state or other source, in order to administer the provisions of division 3 of this article.
(Ordinance adopted 1/12/10)
(a)
Application
for a floodplain development permit shall be presented to the floodplain
administrator on forms furnished by him/her and may include, but not
be limited to, plans in duplicate drawn 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:
(1)
Elevation (in relation to mean sea level), of the lowest floor (including
basement) of all new and substantially improved structures;
(2)
Elevation in relation to mean sea level to which any nonresidential
structure shall be floodproofed;
(3)
A certificate from a registered professional engineer or architect that the nonresidential floodproofed structure shall meet the floodproofing criteria of section 3.06.072(2);
(4)
Description of the extent to which any watercourse or natural drainage
will be altered or relocated as a result of proposed development;
(5)
Maintain a record of all such information in accordance with section 3.06.042(1).
(b)
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 tie effect of such damage on the individual owner;
(3)
The danger that materials may be swept onto other lands to the injury
of others;
(4)
The compatibility of the proposed use with existing and anticipated
development;
(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 floodwaters 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.
(Ordinance adopted 1/12/10)
(a)
The
appeal board, as established by the community, shall hear and render
judgment on requests for variances from the requirements of this article.
(b)
The
appeal board shall hear and render judgment on an appeal only when
it is alleged there is an error in any requirement, decision, or determination
made by the floodplain administrator in the enforcement or administration
of this article.
(c)
Any
person or persons aggrieved by the decision of the appeal board may
appeal such decision in the courts of competent jurisdiction.
(d)
The
floodplain administrator shall maintain a record of all actions involving
an appeal and shall report variances to the Federal Emergency Management
Agency upon request.
(e)
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.
(f)
Variances may be issued for new construction and substantial improvements to be erected on a lot of 1/2 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 section 3.06.043(b) of this division have been fully considered. As the lot size increases beyond the 1/2 acre, the technical justification required for issuing the variance increases.
(g)
Upon consideration of the factors noted above and the intent of this article, the appeal board may attach such conditions to the granting of variances as it deems necessary to further the purpose and objectives of this article (section 3.06.002).
(h)
Variances
shall not be issued within any designated floodway if any increase
in flood levels during the base flood discharge would result.
(i)
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.
(j)
Prerequisites
for granting variances:
(1)
Variances shall only be issued 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)
Showing a good and sufficient cause;
(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 application to which a variance is granted shall be given written
notice that the structure will be permitted to be built with the lowest
floor elevation 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.
(k)
Variances
may be issued by a community for new construction and substantial
improvements and for other development necessary for the conduct of
a functionally dependent use provided that:
