Article I. General Provisions
4.08.010 Statutory authorization.
The Legislature of the State of South Carolina has in SC Code of Laws,
Title 5, Chapters 7, 23, and 25 (Articles 5 and 7) and Title 6, Chapter 7, and
amendments thereto, delegated the responsibility to local governmental units to
adopt regulations designed to promote the public health, safety, and general
welfare of its citizenry. Therefore, the mayor and council of the city of
Travelers Rest, South Carolina does ordain as follows. (Ord. O-13-06 (part),
2006)
4.08.020 Findings of fact.
The flood hazard areas of the city of Travelers Rest are subject to
periodic inundation which results in loss of life, property, health and safety
hazards, disruption of commerce and governmental services, extraordinary public
expenditures of flood protection and relief, and impairment of the tax base, all
of which adversely affect the public health, safety and general
welfare.
Furthermore, these flood losses are caused by the cumulative effect
of obstructions in floodplains causing increases in flood heights and
velocities, and by the occupancy in flood hazard areas by uses vulnerable to
floods or hazardous to other lands which are inadequately elevated,
floodproofed, or otherwise unprotected from flood damages. (Ord. O-13-06 (part),
2006)
4.08.030 Statement of purpose and objectives.
It is the purpose of this chapter to protect human life and health,
minimize property damage, and encourage appropriate construction practices to
minimize public and private losses due to flood conditions by requiring that
uses vulnerable to floods, including facilities which serve such uses, be
protected against flood damage at the time of initial construction. Uses of the
floodplain which are dangerous to health, safety, and property due to water or
erosion hazards, or which increase flood heights, velocities, or erosion are
restricted or prohibited. These provisions attempt to control the alteration of
natural floodplains, stream channels, and natural protective barriers which are
involved in the accommodation of floodwaters, and control filling, grading,
dredging and other development which may increase flood damage or erosion.
Additionally, the ordinance prevents or regulates the construction of flood
barriers which will unnaturally divert floodwaters or which may increase flood
hazards to other lands.
The objectives of this chapter are to protect human
life and health, 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 flood
blight areas, and to insure that potential home buyers are notified that
property is in a flood area. The provisions of the ordinance are intended to
minimize damage to public facilities and utilities such as water and gas mains,
electric, telephone, and sewer lines, streets and bridges located in the
floodplain, and prolonged business interruptions. Also, an important floodplain
management objective of this chapter is to minimize expenditure of public money
for costly flood control projects and rescue and relief efforts associated with
flooding.
Floodplains are an important asset to the community. They perform
vital natural functions such as temporary storage of floodwaters, moderation of
peak flood flows, maintenance of water quality, groundwater recharge, prevention
of erosion, habitat for diverse natural wildlife populations, recreational
opportunities and aesthetic quality. These functions are best served if
floodplains are kept in their natural state. Wherever possible, the natural
characteristics of floodplains and their associated wetlands and water bodies
should be preserved and enhanced. Decisions to alter floodplains, especially
floodways and stream channels, should be the result of careful planning
processes that evaluate resource conditions and human needs. (Ord. O-13-06
(part), 2006)
4.08.040 Lands to which this ordinance applies.
This chapter shall apply to all areas of special flood hazard within the
jurisdiction of the city of Travelers Rest as identified by the Federal
Emergency Management Agency in its Flood Insurance Study, 45045CV001A dated
December 2, 2004, with accompanying maps and other supporting data, which are
adopted by reference and declared to be a part of this chapter. Upon annexation
any special flood hazard areas identified by the Federal Emergency Management
Agency in its Flood Insurance Study for the unincorporated areas of Greenville
County, with accompanying map and other data are adopted by reference and
declared part of this chapter. (Ord. O-13-06 (part), 2006)
4.08.050 Establishment of development permit.
A development permit shall be required in conformance with the provisions
of this chapter prior to the commencement of any development activities. (Ord.
O-13-06 (part), 2006)
4.08.060 Compliance.
No structure or land shall hereafter be located, extended, converted, or
structurally altered without full compliance with the terms of the ordinance
codified in this chapter and other applicable regulations. (Ord. O-13-06 (part),
2006)
4.08.070 Interpretation.
In the interpretation and application of the ordinance codified in this
chapter, all provisions shall be considered as minimum requirements, liberally
construed in favor of the governing body, and deemed neither to limit nor repeal
any other powers granted under state law. This chapter is not intended to
repeal, abrogate, or impair any existing easements, covenants or deed
restrictions. However, where this chapter and another conflict or overlap,
whichever imposes the more stringent restrictions shall prevail. (Ord. O-13-06
(part), 2006)
4.08.080 Partial invalidity and severability.
If any part of this chapter is declared invalid, the remainder of the
ordinance codified in this chapter shall not be affected and shall remain in
force. (Ord. O-13-06 (part), 2006)
4.08.090 Warning and disclaimer of liability.
The degree of flood protection required by this chapter is considered
reasonable for regulatory purposes and is based on scientific and engineering
consideration. Larger floods can and will occur on rare occasions. Flood heights
may be increased by man-made or natural causes. This chapter does not imply that
land outside the areas of special flood hazard or uses permitted within such
areas will be free from flooding or flood damages. This chapter shall not create
liability on the part of the city of Travelers Rest or by any officer or
employee thereof for any flood damages that result from reliance on the
ordinance codified in this chapter or any administrative decision lawfully made
hereunder. (Ord. O-13-06 (part), 2006)
4.08.100 Penalties for violation.
Violation of the provisions of this chapter or failure to comply with any
of its requirements, including violation of conditions and safeguards
established in connection with grants of variance or special exceptions, shall
constitute a misdemeanor. Any person who violates this ordinance or fails to
comply with any of its requirements shall, upon conviction thereof, be fined not
more that five hundred dollars or imprisoned for not more than thirty days, or
both. Each day such violation continues shall be considered a separate offense.
Nothing herein contained shall prevent the city of Travelers Rest from taking
such other lawful action as is necessary to prevent or remedy any violation.
(Ord. O-13-06 (part), 2006)

program as determined by the secretary of interior, or (2) directly by the
secretary of interior in states without approved programs. Some structures or
districts listed on the state or local inventories may not be
“Historic” as cited above, but have been included on the inventories
because it was believed that the structures or districts have the potential for
meeting the “Historic” structure criteria of the DOI. In order for
these structures to meet NFIP historic structure criteria, it must be
demonstrated and evidenced that the South Carolina Department of Archives and
History has individually determined that the structure or district meets DOI
historic structure criteria.

geodetic vertical datum (NGVD).
“National geodetic vertical datum
(NGVD)” means as corrected in 1929, elevation reference points set by
national geodetic survey based on mean sea level.
“New
construction” means structure for which the start of construction
commenced after (the effective date of the first floodplain management code,
ordinance, or standard based upon specific technical base flood elevation data
which establishes the area of special flood hazard) or (specific date). The term
also includes any subsequent improvements to such structure.
“New
manufactured home park or subdivision” means a manufactured home park or
subdivision for which the construction of facilities for servicing the lots on
which the manufactured homes are to be affixed (including at a minimum, the

reconstruction, rehabilitation, addition, or improvement was within one hundred
eighty days of the permit date. The actual start means the first placement of
permanent construction of a structure (including a manufactured home) on a site,
such as the pouring of slabs or footings, installation of piles, construction of
columns, or any work beyond the stage of excavation or the placement of a
manufactured 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
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 the
building, whether or not that alteration affects the external dimensions of the
building.
“Structure” means a walled and roofed building, a
manufactured home, including a gas or liquid storage tank, or other man-made

“substantial improvement.”
“Substantial improvement”
means any repair, reconstruction, rehabilitation, addition, or other improvement
of a structure, the cost of which equals or exceeds fifty percent of the market
value of the structure before the start of construction of the improvement. This
term includes structures that have incurred substantial damage, regardless of
the actual repair work performed. The term does not, however, include either:
(1) any project of improvement to 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 (does not include American with
Disabilities Act Compliance Standards); or, (2) any alteration of a historic
structure, provided that the alteration will not preclude the structure’s
continued designation as a historic structure. Permits shall be cumulative for a
period of five years. If the improvement project is conducted in phases, the
total of all costs associated with each phase, beginning with the issuance of
the first permit, shall be utilized to determine whether “substantial
improvement” will occur.
“Substantially improved existing
manufactured home park or subdivision” means where the repair,
reconstruction, rehabilitation or improvement of the streets, utilities and pads
equals or exceeds fifty percent of the value of the streets, utilities and pads
before the repair, reconstruction, or improvement
commenced.

4.08.160 Administrative procedures.
(a) Inspections of Work in Progress. As the work pursuant to a permit
progresses, the local administrator shall make as many inspections of the work
as may be necessary to ensure that the work is being done according to the
provisions of the local ordinance and the terms of the permit. In exercising
this power, the administrator has a right, upon presentation of proper
credentials, to enter on any premises within the territorial jurisdiction at any
reasonable hour for the purposes of inspection or other enforcement
action.
(b) Stop-Work Orders. Whenever a building or part thereof is being
constructed, reconstructed, altered, or repaired in violation of this chapter,
the administrator may order the work to be immediately stopped. The stop-work
order shall be in writing and directed to the person doing the work. The
stop-work order shall state the specific work to be stopped, the specific
reasons for the stoppage, and the conditions under which the work may be
resumed. Violation of a stop-work order constitutes a
misdemeanor.
(c) Revocation of Permits. The local administrator may revoke
and require the return of the development permit by notifying the permit holder
in writing, stating the reason for the revocation. Permits shall be revoked for
any substantial departure from the approved application, plans, or
specifications; for refusal or failure to comply with the requirements of state
or local laws; or for false statements or misrepresentations made in securing
the permit. Any permit mistakenly issued in violation of an applicable state or
local law may also be revoked.
(d) Periodic Inspections. The local
administrator and each member of his inspections department shall have a right,
upon presentation of proper credentials, to enter on any premises within the
territorial jurisdiction of the department at any reasonable hour for the
purposes of inspection or other enforcement action.
(e) Violations to be
Corrected. When the local administrator finds violations of applicable state and
local laws, it shall be his duty to notify the owner or occupant of the building
of the violation. The owner or occupant shall immediately remedy each of the
violations of law on the property he owns.
(f) Actions in Event of Failure
to Take Corrective Action. If the owner of a building or property shall fail to
take prompt corrective action, the administrator shall give him written notice,
by certified or registered mail to his last known address or by personal
service, that:
(1) The building or property is in violation of the flood
damage prevention ordinance;
(2) A hearing will be held before the local
administrator at a designated place and time, not later than ten days after the
date of the notice, at which time the owner shall be entitled to be heard in
person or by counsel and to present arguments and evidence pertaining to the
matter; and
(3) Following the hearing, the local administrator may issue
such order to alter, vacate, or demolish the building; or to remove fill as
appears appropriate.
(g) Order to Take Corrective Action. If, upon a hearing
held pursuant to the notice prescribed above, the administrator shall find that
the building or development is in violation of the flood damage prevention
ordinance, he shall make an order in writing to the owner, requiring the owner
to remedy the violation within such period, not less than sixty days, the
administrator may prescribe; provided that where the administrator finds that
there is imminent danger to life or other property, he may order that corrective
action be taken in such lesser period as may be feasible.
(h) Appeal. Any
owner who has received an order to take corrective action may appeal from the
order to the local elected governing body by giving notice of appeal in writing
to the administrator and the clerk within ten days following issuance of the
final order. In the absence of an appeal, the order of the administrator shall
be final. The local governing body shall hear an appeal within a reasonable time
and may affirm, modify and affirm, or revoke the order.
(i) Failure to
Comply with Order. If the owner of a building or property fails to comply with
an order to take corrective action from which no appeal has been taken, or fails
to comply with an order of the governing body following an appeal, he shall be
guilty of a misdemeanor and shall be punished in the discretion of the court.

Article IV. Provisions for Flood Hazard Reduction
4.08.170 General standards.
Development may not occur in the floodplain where alternative locations
exist due to the inherent hazards and risks involved. Before a permit is issued,
the applicant shall demonstrate that new structures cannot be located out of the
floodplain and that encroachments onto the floodplain are minimized. In all
areas of special flood hazard the following provisions are required:
(a) All
new construction and substantial improvements shall be anchored to prevent
flotation, collapse, or lateral movement of the structure;
(b) All new
construction and substantial improvements shall be constructed with
flood-resistant materials and utility equipment resistant to flood
damage;
(c) All new construction or substantial improvements shall be
constructed by methods and practices that minimize flood
damages;
(d) Electrical, ventilation, plumbing, heating and air conditioning
equipment (including ductwork), 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. This requirement does not preclude the
installation of outdoor faucets for shower heads, sinks, hoses, etc., as long as
cutoff devices and backflow devices are installed to prevent contamination to
the service components and thereby minimize any flood damages to the
building;
(e) All new and replacement water supply systems shall be designed
to minimize or eliminate infiltration of floodwaters into the
system;
(f) New and replacement sanitary sewage systems shall be designed to
minimize or eliminate infiltration of floodwaters into the systems and
discharges from the systems into floodwaters;
(g) On-site waste disposal
systems shall be located and constructed to avoid impairment to them or
contamination from them during flooding;
(h) Any alteration, repair,
reconstruction, or improvement to a structure that is in compliance with the
provisions of this chapter, shall meet the requirements of “new
construction” as contained in this chapter. This includes post-FIRM
development and structures;
(i) Nonconforming Buildings or Uses.
Nonconforming buildings or uses may not be enlarged, replaced, or rebuilt unless
such enlargement or reconstruction is accomplished in conformance with the
provisions of this chapter. Provided, however, nothing in this chapter shall
prevent the repair, reconstruction, or replacement of an existing building or
structure located totally or partially within the floodway, provided that the
bulk of the building or structure below base flood elevation in the floodway is
not increased and provided that such repair, reconstruction, or replacement
meets all of the other requirements of this chapter;
(j) American with
Disabilities Act (ADA). A building must meet the specific standards for
floodplain construction outlined in Section 4.08.180, as well as any applicable
ADA requirements. The ADA is not a justification for issuing a variance or
otherwise waiving these requirements. Also, the cost of improvements required to
meet the ADA provisions shall be included in the costs of the improvements for
calculating substantial improvement; and
(k) Critical Facilities.
Construction of new or substantially improved critical facilities shall be, to
the extent possible, located outside the limits of the special flood hazard area
(SFHA) (one hundred-year floodplain). Construction of new critical facilities
shall be permissible within the SFHA if not feasible alternative site is
available. Critical facilities constructed within the SFHA shall have the lowest
floor elevated three feet (approximate five hundred-year floodplain) or more
above the level of the base flood elevation at the site. Floodproofing and
sealing measures must be taken to ensure that toxic substances will not be
displaced by or released into floodwaters. Access routes elevated to or above
the level of the base flood elevation shall be provided to all critical
facilities to the extent possible. (Ord. O-13-06 (part), 2006)
4.08.180 Specific standards.
In all areas of special flood hazard where base flood elevation data has
been provided, as set forth in Section 4.08.040 or Section 4.08.150(j), the
following provisions are required:
(a) Residential Construction. New
construction or substantial improvement of any residential structure (including
manufactured homes) shall have the lowest floor elevated no lower than two feet
above the base flood elevation. No basements are permitted. Should solid
foundation perimeter walls be used to elevate a structure, openings sufficient
to facilitate the unimpeded movements of floodwaters shall be provided in
accordance with subsection (e) of this section.
(b) Nonresidential
Construction. New construction or substantial improvement of any commercial,
industrial, or nonresidential structure (including manufactured homes) shall
have the lowest floor elevated no lower than two feet above the level of the
base flood elevation. Should solid foundation perimeter walls be used to elevate
a structure, openings sufficient to facilitate the unimpeded movements of
floodwaters shall be provided in accordance with subsection (e) of this section.
No basements are permitted. Structures located in A-zones may be floodproofed in
lieu of elevation provided that all areas of the structure below the required
elevation are watertight with walls substantially impermeable to the passage of
water, using structural components having the capability of resisting
hydrostatic and hydrodynamic loads and the effect of buoyancy. A registered,
professional engineer or architect shall certify that the standards of this
subsection are satisfied. Such certifications shall be provided to the official
as set forth in Sections 4.08.140(g) and 4.08.140(i). A variance may be
considered for wet-floodproofing agricultural structures in accordance with the
criteria outlined in Section 4.08.220 of this chapter. Agricultural structures
not meeting the criteria of Section 4.08.220 must meet the nonresidential
construction standards and all other applicable provisions of this chapter.
Structures that are floodproofed are required to have an approved maintenance
plan with an annual exercise. The local administrator must approve the
maintenance plan and notification of the annual exercise shall be provided to
same.
(c) Manufactured Homes.
(1) Manufactured homes that are placed or
substantially improved on sites outside a manufactured home park or subdivision,
in a new manufactured home park or subdivision, in an expansion to an existing
manufactured home park or subdivision, or in an existing manufactured home park
or subdivision on which a manufactured home has incurred “substantial
damage” as the result of a flood, must be elevated on a permanent
foundation such that the lowest floor of the manufactured home is elevated no
lower than two feet above the base flood elevation and be securely anchored to
an adequately anchored foundation system to resist flotation, collapse and
lateral movement.
(2) Manufactured homes that are to be placed or
substantially improved on sites in an existing manufactured home park or
subdivision that are not subject to the provisions of subsection (c)(1) of this
section must be elevated so that the lowest floor of the manufactured home is
elevated no lower than two feet above the base flood elevation, and be securely
anchored to an adequately anchored foundation to resist flotation, collapse and
lateral movement.
(3) Manufactured homes shall be anchored to prevent
flotation, collapse, or lateral movement. For the purpose of this requirement,
manufactured homes must be anchored to resist flotation, collapse, or lateral
movement in accordance with Section 19-425.39 of the South Carolina Manufactured
Housing Board Regulations, effective date May 25, 1990, as amended.
Additionally, when the elevation requirement would be met by an elevation of the
chassis at least thirty-six inches or less above the grade at the sight,
reinforced piers or other foundation elements of at least equivalent strength
shall support the chassis. When the elevation of the chassis is above thirty-six
inches in height an engineering certification is required.
(4) An evacuation
plan must be developed for evacuation of all residents of all new, substantially
improved or substantially damaged manufactured home parks or subdivisions
located within flood-prone areas. This plan shall be filed with and approved by
the local administrator and the local emergency preparedness
coordinator.
(d) Recreational Vehicles. A recreational vehicle is ready for
highway use if it is on wheels or jacking system, is attached to the site only
by quick-disconnect type utilities and security devices, and has no permanently
attached additions. Recreational vehicles placed on sites shall either be on
site for fewer than one hundred eighty consecutive days and be fully licensed
and ready for highway use, or meet the requirements of Section 4.08.140 and
Section 4.08.170 and subsection (c) of this section.
(e) Elevated Buildings.
New construction or substantial improvements of elevated buildings that include
fully enclosed areas that are usable solely for the parking of vehicles,
building access, or storage in an area other than a basement, and which are
subject to flooding shall be designed to preclude finished space and be designed
to automatically equalize hydrostatic flood forces on exterior walls by allowing
for the entry and exit of floodwaters.
(1) Designs for complying with this
requirement must either be certified by a professional engineer or architect or
meet the following minimum criteria:
(A) Provide a minimum of two openings
on different walls having a total net area of not less than one square inch for
every square foot of enclosed area subject to flooding;
(B) The bottom of
all openings shall be no higher than one foot above grade;
(C) Openings may
be equipped with screens, louvers, valves, or other coverings or devices
provided they permit the automatic flow of floodwaters in both directions;
and
(D) Fill placed around foundation walls must be graded so that the grade
inside the enclosed area is equal to or higher than the adjacent grade outside
the building on at least one side of the building.
(2) Hazardous Velocities.
Hydrodynamic pressure must be considered in the design of any foundation system
where velocity waters or the potential for debris flow exists. If flood
velocities are excessive (greater than five feet per second), foundation systems
other than solid foundation walls should be considered so that obstructions to
damaging flood flows are minimized.
(3) Access to the enclosed area shall be
the minimum necessary to allow for parking of vehicles (garage door) or limited
storage of maintenance equipment used in connection with the premises (standard
exterior door) or entry to the living area (stairway or elevator).
(4) The
interior portion of such enclosed area shall not be partitioned or finished into
separate rooms, except to enclose a single storage area and must be void of
utilities except for essential lighting as required, and cannot be temperature
controlled. One wet location switch and/or outlet connected to a ground fault
interrupt breaker may be installed below the required lowest floor elevation
specified in subsections (a) through (c) of this section.
(5) All
construction materials below the required lowest floor elevation specified in
subsections (a) through (c) of this section should be of flood-resistant
materials.
(f) Temporary Development. Certain types of structures (e.g.,
fruit stands, construction site offices, portable toilets, etc.) may be situated
temporarily on flood-prone property without having to comply with the elevation
or floodproofing criteria of subsections (a) and (b) of this section,
respectively, provided that the following criteria are met:
(1) All
applicants must submit to the local administrator, prior to the issuance of the
development permit, a written plan for the removal of any temporary structures
or development in the event of a hurricane or flashflood warning notification.
The plan shall be reviewed and approved in writing, and must include the
following information:
(A) A specified time period for which the temporary
use will be permitted,
(B) The name, address and phone number of the
individual responsible for the removal of temporary structures or
development,
(C) The time frame prior to the event at which any structures
will be removed (i.e., minimum of seventy-two hours before landfall of a
hurricane or immediately upon flood warning notification),
(D) A copy of the
contract or other suitable instrument with a trucking company to insure the
availability of removal equipment when needed,
(E) Designation, accompanied
by documentation, of a location outside the floodplain to which any temporary
structure will be moved,
(F) A determination of permanent structures which
would be adversely affected by increased flooding upstream or downstream, and a
method for covering this liability, such as a performance bond, and
(G) A
plan to restore the area to its natural condition once the temporary permit
expires or the temporary use is terminated, whichever is first;
(2) The
structure is mobile, or can be made so, and is capable of being removed from the
site with a maximum of four hours warning;
(3) The structure will not remain
on the property for more than one hundred eighty days.
(g) Accessory
Structures. An accessory structure or garage, the cost of which is greater than
three thousand dollars, must comply with the elevated structure requirements of
subsections (b) and (e) of this section. When accessory structures of three
thousand dollars or less are to be placed in the floodplain, the following
criteria shall be met:
(1) Accessory structures shall not be used for human
habitation (including work, sleeping, living, cooking or restroom
areas);
(2) Accessory structures shall be designed to have low-flood damage
potential;
(3) Accessory structures shall be constructed and placed on the
building site so as to offer the minimum resistance to the flow of
floodwaters;
(4) Accessory structures shall be firmly anchored to prevent
flotation, collapse, or lateral movement of the structure;
(5) Service
facilities such as electrical and heating equipment shall be installed in
accordance with Section 400.4; and
(6) Openings to relieve hydrostatic
pressure during a flood shall be provided below base flood elevation in
conformance with subsection (e) of this section.
(h) Floodways. Located
within areas of special flood hazard established in Section 4.08.040, are areas
designated as floodways. The floodway is an extremely hazardous area due to the
velocity of floodwaters that carry debris and potential projectiles and has
erosion potential. The following provisions shall apply within such
areas:
(1) No encroachments, including fill, new construction, substantial
improvements, additions, and other developments shall be permitted unless it has
been demonstrated through hydrologic and hydraulic analyses performed in
accordance with standard engineering practice that the proposed encroachment
would not result in any increase in the flood levels during the occurrence of
the base flood. Such certification and technical data shall be presented to the
local administrator;
(2) If subsection (h)(1) of this section is satisfied,
all new construction and substantial improvements shall comply with all
applicable flood hazard reduction provisions of Article IV of this
chapter;
(3) Stream crossings for any purpose (i.e., timber harvesting
operations), if temporary, shall be permitted in accordance with subsection (f)
of this section. Otherwise, the development shall comply with all applicable
flood hazard reduction provisions of Article IV of this chapter;
(4) No
manufactured homes shall be permitted, except in an existing manufactured home
park or subdivision. A replacement manufactured home may be placed on a lot in
an existing manufactured home park or subdivision provided the anchoring and the
elevation standards of subsection (c) of this section are
met;
(5) Permissible uses within floodways may include: general farming,
pasture, outdoor plant nurseries, horticulture, forestry, wildlife sanctuary,
game farm, and other similar agricultural, wildlife and related uses. Also,
lawns, gardens, play areas, picnic grounds, and hiking and horseback riding
trails are acceptable uses, provided that they do not employ structures or fill.
Substantial development of a permissible use may require a no-rise
certification. The uses listed in this subsection are permissible only if and to
the extent that they do not cause any increase in base flood
elevations.
(i) Fill. Fill is discouraged because storage capacity is
removed from floodplains. Elevating buildings by other methods must be
considered. An applicant shall demonstrate that fill is the only alternative to
raising the building to at least two feet above the base flood elevation, and
that the amount of fill used will not affect the flood storage capacity or
adversely affect adjacent properties. The following provisions shall apply to
all fill placed in the special flood hazard area:
(1) Fill may not be placed
in the floodway unless it is in accordance with subsection (h)(1) of this
section;
(2) Fill may not be placed in tidal or nontidal wetlands without
the required state and federal permits;
(3) Fill must consist of soil and
rock materials only. A registered professional geotechnical engineer may use
dredged material as fill only upon certification of suitability. Landfills,
rubble fills, dumps, and sanitary fills are not permitted in the
floodplain;
(4) Fill used to support structures must comply with ASTM
Standard D-698, and its suitability to support structures certified by a
registered, professional engineer;
(5) Fill slopes shall be no greater than
two horizontal to one vertical. Flatter slopes may be required where velocities
may result in erosion; and
(6) The use of fill shall not increase flooding
or cause drainage problems on neighboring properties. (Ord. O-13-06 (part),
2006)
4.08.190 Standards for streams without established base flood elevations and/or floodways.
Located within the areas of special flood hazard established in Section
4.08.040, are small streams where no base flood data has been provided or where
no floodways have been identified. The following provisions apply within such
areas:
(a) No encroachments, including fill, new construction, substantial
improvements or new development shall be permitted within one hundred feet of
the stream bank unless certification with supporting technical data by a
registered, professional engineer is provided demonstrating that such
encroachments shall not result in any increase in flood levels during the
occurrence of the base flood discharge.
(b) If subsection (a) of this
section is satisfied and base flood elevation data is available from other
sources, all new construction and substantial improvements within such areas
shall comply with all applicable flood hazard ordinance provisions of Article IV
of this chapter and shall be elevated or floodproofed in accordance with
elevations established in accordance with Section 4.08.150(j). Data from
preliminary, draft, and final flood insurance studies constitutes best available
data. If an appeal is pending on the study in accordance with 44 CFR Ch. 1, Part
67.5 and 67.6, the data does not have to be used. When base flood elevation data
is not available from a federal, state, or other source, the lowest floor shall
be elevated at least three feet above the highest adjacent grade. (Ord. O-13-06
(part), 2006)
4.08.200 Standards for subdivision proposals.
(a) All subdivision proposals shall have public utilities and facilities
such as sewer, gas, electrical, and water systems located and constructed to
minimize flood damage. An access road at or above the base flood elevation shall
be provided to allow emergency access during flood conditions.
(b) All
subdivision proposals shall have adequate drainage provided to reduce exposure
to flood hazards.
(c) Base flood elevation data shall be provided for
subdivision proposals and other proposed development that is greater than the
lesser of five lots or five acres. Development of detailed floodway data will be
required should the applicant wish to appeal the setback requirements of Section
4.08.190(a). (Ord. O-13-06 (part), 2006)
4.08.210 Standards for areas of shallow flooding (AO zones).
Located within the areas of special flood hazard established in Section
4.08.040, are areas designated as shallow flooding. The following provisions
shall apply within such areas:
(a) All new construction and substantial
improvements of residential structures shall have the lowest floor elevated to
the depth number specified on the flood insurance rate map, in feet, above the
highest adjacent grade. If no depth number is specified, the lowest floor shall
be elevated at least three feet above the highest adjacent grade.
(b) All
new construction and substantial improvements of nonresidential structures
shall:
(1) Have the lowest floor elevated to the depth number specified on
the flood insurance rate map, in feet, above the highest adjacent grade. If no
depth number is specified, the lowest floor shall be elevated at least three
feet above the highest adjacent grade; or
(2) Be completely floodproofed
together with attendant utility and sanitary facilities to or above that level
so that any space below that level 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. (Ord. O-13-06 (part), 2006)
Article V. Variance Procedures
4.08.220 Establishment of appeal board.
The appeal board as established by the city of Travelers Rest shall hear
and decide requests for variances from the requirements of this chapter. (Ord.
O-13-06 (part), 2006)
4.08.230 Right to appeal.
Any person aggrieved by the decision of the appeal board or any taxpayer
may appeal such decision to the court. (Ord. O-13-06 (part), 2006)
4.08.240 Historic structures.
Variances may be issued for the repair of rehabilitation of historic
structures upon the 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. (Ord. O-13-06 (part), 2006)
4.08.250 Agricultural structures.
Variances may be issued to wet floodproof an agricultural structure in
accordance with Technical Bulletin 7-93, Wet Floodproofing Requirements for
Structures Located in Special Flood Hazard Areas in accordance with the National
Flood Insurance Program, document number FIA-TB-7, dated 12/93, and available
from the Federal Emergency Management Agency. In order to minimize flood damages
during the base flood and the threat to public health and safety, the structure
must meet all of the conditions and considerations of Section 4.08.290(d), this
section, and the following standards:
(a) Use of the structure must be
limited to agricultural purposes as listed below:
(1) Pole frame buildings
with open or closed sides used exclusively for the storage of farm machinery and
equipment,
(2) Steel grain bins and steel frame corn cribs,
(3) General
purpose barns for the temporary feeding of livestock which are open on at least
one side,
(4) For livestock confinement buildings, poultry houses, dairy
operations, and similar livestock operations, variances may not be issued for
structures that were substantially damaged. New construction or substantial
improvement of such structures must meet the elevation requirements of Section
4.08.180(b) of this chapter; and
(5) Detached garages and storage sheds
solely used for parking and limited storage in connection with agricultural uses
only, which are no greater than four hundred square feet in area;
(b) The
agricultural structure must be built or rebuilt, in the case of an existing
building which is substantially damaged, with flood-resistant materials for the
exterior and interior building components and elements below the base flood
elevation;
(c) The agricultural structure must be adequately anchored to
prevent flotation, collapse, or lateral movement. All of the structure’s
components must be capable of resisting specific flood-related forces including
hydrostatic, buoyancy, hydrodynamic, and debris impact forces. Where flood
velocities exceed five feet per second, fast-flowing floodwaters can exert
considerable pressure on the building’s enclosure walls or foundation
walls;
(d) The agricultural structure must meet the venting requirement of
Section 4.08.180(e)(1) of this chapter;
(e) Any mechanical, electrical, or
other utility equipment must be located above the base flood elevation so that
they are contained within a watertight, floodproofed enclosure that is capable
of resisting damage during flood conditions. The structure must comply with
Section 4.08.170(d) of this chapter;
(f) The agricultural structure must
comply with the floodway encroachment provisions of Section 4.08.180(h) of this
chapter; and
(g) Major equipment, machinery, or other contents must be
protected. Such protection may include protective watertight floodproofed areas
within the building, the use of equipment hoists for readily elevating contents,
permanently elevating contents on pedestals or shelves above the base flood
elevation, or determining that property owners can safely remove contents
without risk to lives and that the contents will be located to a specified site
out of the floodplain in accordance with the temporary development provisions of
Section 4.08.180(f). (Ord. O-13-06 (part), 2006)
4.08.260 Considerations.
In passing upon such applications, the appeal board shall consider all
technical evaluations, all relevant factors, all standards specified in other
sections of this chapter, and:
(a) The danger that materials may be swept
onto other lands to the injury of others;
(b) The danger to life and
property due to flooding or erosion damage, and the safety of access to the
property in times of flood for ordinary and emergency vehicles;
(c) The
susceptibility of the proposed facility and its contents to flood damage and the
effect of such damage on the individual owner;
(d) The importance of the
services provided by the proposed facility to the community;
(e) The
necessity to the facility of a waterfront location, where
applicable;
(f) The availability of alternative locations, not subject to
flooding or erosion damage, for the proposed use;
(g) The compatibility of
the proposed use with existing and anticipated development, and the relationship
of the proposed use to the comprehensive plan and floodplain management program
for that area;
(h) 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;
(i) The costs of providing governmental
services during and after flood conditions including maintenance and repair of
public utilities and facilities such as sewer, gas, electrical and water
systems, and streets and bridges; and
(j) Agricultural structures must be
located in wide, expansive floodplain areas, where no other alternative location
for the agricultural structure exists. The applicant must demonstrate that the
entire farm acreage, consisting of a contiguous parcel of land on which the
structure is to be located, must be in the special flood hazard area and no
other alternative locations for the structure are available. (Ord. O-13-06
(part), 2006)
4.08.270 Findings.
Findings listed above shall be submitted to the appeal board, in writing,
and included in the application for a variance. Additionally, comments from the
Department of Natural Resources, Land Resources and Conservation Districts
Division, State Coordinator’s Office, must be taken into account and
included in the permit file. (Ord. O-13-06 (part), 2006)
4.08.280 Floodways.
Variances shall not be issued within any designated floodway if any
increase in flood levels during the base flood discharge would result. (Ord.
O-13-06 (part), 2006)
4.08.290 Conditions.
Upon consideration of the factors listed above and the purposes of this
chapter, the appeal board may attach such conditions to the granting of
variances as it deems necessary to further the purposes of this chapter. The
following conditions shall apply to all variances:
(a) Variances may not be
issued when the variance will make the structure in violation of other federal,
state, or local laws, regulations or ordinances;
(b) Variances shall only be
issued upon a determination that the variance is the minimum necessary,
considering the flood hazard, to afford relief;
(c) Variances shall only be
issued upon a showing of good and sufficient cause, a determination that failure
to grant the variance would result in exceptional hardship, and a determination
that the granting of a variance will not result in increased flood heights,
additional threats to public safety, extraordinary public expense, create
nuisance, cause fraud on or victimization of the public, or conflict with
existing local laws or ordinances;
(d) Any applicant to whom a variance is
granted shall be given written notice specifying the difference between the base
flood elevation and the elevation to which the structure is to be built and a
written statement that the cost of flood insurance will be commensurate with the
increased risk resulting from the reduced lowest floor elevation. Such
notification shall be maintained with a record of all variance
actions;
(e) The local administrator shall maintain the records of all
appeal actions and report any variances to the Federal Emergency Management
Agency upon request;
(f) Variances shall not be issued for unpermitted
development or other development that is not in compliance with the provisions
of this chapter. Violations must be corrected in accordance with Section
4.08.160(e) of this chapter. (Ord. O-13-06 (part), 2006)
Article VI. Legal Status Provisions
4.08.300 Effects on rights and liabilities under the existing flood damage prevention ordinance.
This chapter in part comes forward by re-enactment of some of the
provisions of the flood damage prevention ordinance enacted in 1997, as amended,
and it is not the intention to repeal but rather to re-enact and continue to
enforce without interruption of such existing provisions, so that all rights and
liabilities that have accrued there under are reserved and may be enforced. The
