General Provisions
Sec 23-11-200. Statutory authorization.
Pursuant to the authority granted to the Board of County Commissioners by the
Legislature of the State of Colorado in Title 29, Article 20, and Title 30, Article 28, C.R.S., the
Board of County Commissioners does hereby adopt the following FLOODPLAIN MANAGEMENT
ORDINANCE (referred to generally herein as "ORDINANCE").
Sec 23-11-210. Disclaimer of liability.
The degree of FLOOD protection required by this ORDINANCE is considered reasonable
for regulatory purposes and is based on scientific and engineering considerations. On rare
occasions greater FLOODS than contemplated in the creation of this ORDINANCE can and will
occur and FLOOD heights may be increased by man-made or natural causes. This ORDINANCE

does not imply that land outside the SPECIAL FLOOD HAZARD AREA or USES permitted within
such areas will be free from FLOODING or FLOOD damages. This ORDINANCE shall not create
liability on the part of the COUNTY, any officer or employee thereof for any FLOOD damages that
result from reliance on this ORDINANCE or any administrative decision lawfully made thereunder.
Sec 23-11-220. Findings of fact.
The SPECIAL FLOOD HAZARD AREAS of the COUNTY are subject to periodic
inundation which results in health and safety hazards, loss of life and property, disruption of
commerce and governmental services, extraordinary public expenditures for FLOOD protection
and relief, and impairment of the tax base, all of which adversely affect the public health, safety
and general welfare of the residents of the COUNTY.
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 SPECIAL 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.
Sec 23-11-230. Statement of purpose.
A. It is the purpose of this ORDINANCE to promote 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 which have
historically been undertaken at the expense of the general public;
4. Minimize prolonged business interruptions;
5. Minimize damage to CRITICAL FACILITIES, infrastructure, and other public facilities
such as water, sewer and gas mains; electric and communications stations, substations
and power plants, streets and bridges located in FLOODPLAINS;
6. Help maintain a stable tax base by providing for the sound USE and DEVELOPMENT of
flood prone areas so as to minimize future FLOOD blight areas; and
7. Ensure that potential buyers are notified that property is in a SPECIAL FLOOD HAZARD
AREA.
B. In order to accomplish its purpose, this ORDINANCE does the following:
1. Restricts or prohibits USES that are dangerous to health, safety and property in times of
FLOOD or cause excessive increases in FLOOD heights or velocities;

2. Requires that USES vulnerable to FLOODS, including facilities which serve such USES,
be protected against FLOOD damage at the time of initial construction;
3. Controls the alteration of natural FLOODPLAINS, stream CHANNELS and natural
protective barriers, which are involved in the accommodation of FLOOD waters;
4. Controls filling, grading, dredging and other DEVELOPMENT which may increase
FLOOD damage; and
5. Prevents or regulates the construction of FLOOD barriers which will unnaturally divert
FLOOD waters or which may increase FLOODING in other lands.
C. It is also the purpose of this ORDINANCE to ensure that the COUNTY'S requirements
meet the minimum requirements of the Federal Emergency Management Agency's
("FEMA") Flood Insurance Program Regulations [found at 44 CFR Parts 59, 60, 65, and
70 (2010), and referred to herein to each individual section, or collectively as "the Federal
Flood Insurance Program Regulations'], and the Colorado Water Conservation Board
("CWCB") "Rules and Regulations for Regulatory Floodplains in Colorado" (referred to
herein as "CWCB FLOODPLAIN Rules"), adopted in effect as of January 14, 2011 (found
at 2 CCR 408-1). As such the National FLOOD Insurance Program regulations and the
CWCB FLOODPLAIN Rules are incorporated herein by reference. In the event this
ORDINANCE conflicts with Federal or State laws and/or regulations, the more restrictive
law or regulation will control.
Sec. 23-11-240. Lands to which this ORDINANCE applies.
This ORDINANCE shall apply to all SPECIAL FLOOD HAZARD AREAS and areas
removed from the FLOODPLAIN by the issuance of a FEMA LOMR-F within the jurisdiction of
unincorporated Weld County, Colorado.
Sec. 23-11-250. Basis for establishing the SPECIAL FLOOD HAZARD AREA.
The SPECIAL FLOOD HAZARD AREA identified by FEMA in a scientific and engineering
report entitled, "The Flood Insurance Study for Unincorporated Weld County and Town of Eaton,
Colorado," dated September 22, 1999, with accompanying FIRM and FBFM and any revisions
thereto are hereby adopted by reference and declared to be part of this ORDINANCE. These
SPECIAL FLOOD HAZARD AREAS identified by the FIS and attendant mapping are the
minimum area of applicability of this ORDINANCE and may be supplemented by studies
designated and approved by the Board of County Commissioners, CWCB, and FEMA. The
FLOODPLAIN ADMINISTRATOR shall keep a copy of the FIS, FIRMs, and/or FBFMs on file and
available for public inspection.
Sec. 23-11-260. Establishment of FLOODPLAIN DEVELOPMENT PERMIT.
A FLOODPLAIN DEVELOPMENT PERMIT shall be required for all USES occurring within
the FEMA mapped 100 -YEAR FLOODPLAIN to ensure conformance with the provisions of this
ORDINANCE and Federal and State regulations.

D. Zones AE and A1 -A30 are SPECIAL FLOOD HAZARD AREAS where BASE FLOOD
ELEVATIONS and FLOOD HAZARD factors have been determined by FEMA.
E. Zone B and Zone X (shaded) are SPECIAL FLOOD HAZARD AREAS that are between
the limits of the 100 -YEAR and the 500 -YEAR FLOOD.
F. Zone C and Zone X (unshaded) are SPECIAL FLOOD HAZARD AREAS that are at
minimal risk of FLOODING.
START OF CONSTRUCTION (pertaining to BUILDINGS or STRUCTURES): The date the
building permit was issued, including building permits for SUBSTANTIAL IMPROVEMENTS,
provided that the actual START OF CONSTRUCTION, repair, reconstruction, placement or other
improvement was within one -hundred eighty (180) days of the permit date. The actual start
means the first placement of permanent construction of a STRUCTURE on a site, such as the
pouring of slab or footings, the installation of piles, the 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 a BASEMENT, 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 SUBSTANTIAL
IMPROVEMENTS, the actual START OF CONSTRUCTION means the first alteration of any wall,
ceiling, floor, or other structural part of a BUILDING, whether or not that alteration affects the
external dimensions of the BUILDING.
STRUCTURE: Anything that is built, constructed or erected, an edifice or building of any kind, or
any piece of work artificially built up or composed of parts joined together in some definite
manner, but not including poles, lines, cables or distribution facilities of public utilities. Includes a
walled or roofed BUILDING, a gas or storage tank that is principally above ground, and
MANUFACTURED HOMES.
SUBSTANTIAL DAMAGE: Damage of any origin sustained by a STRUCTURE whereby the cost
of restoring the STRUCTURE to its before damaged condition would equal or exceed fifty percent
(50%) of the market value of the STRUCTURE just prior to when the damage occurred.
SUBSTANTIAL IMPROVEMENT: Any repair, reconstruction or improvement of a STRUCTURE
the cost of which equals or exceeds fifty percent (50%) of the market value of the STRUCTURE
before the START OF CONSTRUCTION of the improvement. This includes STRUCTURES
which have incurred SUBSTANTIAL DAMAGE, regardless of the actual repair work performed.
The term does not, however, include either:
A. Any project for improvement of a STRUCTURE to comply with existing State or local
health, sanitary, or safety code specifications which are solely necessary to assure safe
living conditions; or
B. Any alternation of a HISTORIC STRUCTURE provided that the alteration will not preclude
the STRUCTURE'S continued designation as a HISTORIC STRUCTURE.

VARIANCE: A grant of relief to a person from a requirement, or requirements, of this
ORDINANCE when specific enforcement would result in unnecessary hardship. A VARIANCE,
therefore, permits construction or DEVELOPMENT in a manner otherwise prohibited by this
ORDINANCE.
VIOLATION: The failure of a STRUCTURE or other DEVELOPMENT to be fully compliant with
this ORDINANCE.
WATERCOURSE: means a natural or artificial channel through which stormwater or floodwater
can flow, either regularly or infrequently.
WATER SURFACE ELEVATION: The height, in relation to the National Geodetic Vertical Datum
(NGVD) of 1929, North American Vertical Datum (NAVD) of 1988, or other datum where specified
of FLOODS of various magnitudes and frequencies in the FLOODPLAINS of riverine areas.
WATERTIGHT: Impermeable to the passage of water and capable of resisting the hydrostatic and
hydrodynamic loads and the effects of buoyancy during a BASE FLOOD.

Per 44CFR 65.3, the applicant shall submit a LOMR to FEMA for acceptance and
approval within 60 days after the BASE FLOOD ELEVATIONS are determined.
E. Per 44CFR 60.3(a), all subdivision proposals including the placement of
MANUFACTURED HOME PARKS and subdivisions shall conform to the following
requirements:
1. All subdivision proposals including the placement of MANUFACTURED HOME parks
shall be reasonably safe from FLOODING. If a subdivision or other DEVELOPMENT
proposal is in a flood -prone area, the proposal shall minimize FLOOD damage;
2. All proposals for the development of subdivisions including the placement of
MANUFACTURED HOME PARKS and subdivisions shall meet the FLOODPLAIN
DEVELOPMENT PERMIT requirements;
3. Adequate drainage paths shall be provided to reduce exposure to FLOOD hazards;
and
4. Public utilities and facilities such as sewer, gas, electrical, and water systems shall be
located and constructed to minimize or eliminate FLOOD damage.
Sec. 23-11-380. Specific standards for FLOODPLAINS with BASE FLOOD ELEVATIONS
(Zones Al -A30, AH, AO, and AE).
In addition to the general standards in Section 23-11-360 and specific standards for
Approximate Floodplains in Section 23-11-370, the following provisions are required for all NEW
CONSTRUCTION AND SUBSTANTIAL IMPROVEMENTS that are located in SPECIAL FLOOD
HAZARD AREAS designated as Zones Al through A30, AH, AO, and AE:
A. Per 44CFR 60.3(c), when a regulatory FLOODWAY has not been designated, the
FLOODPLAIN ADMINISTRATOR shall require that no NEW CONSTRUCTION,
SUBSTANTIAL IMPROVEMENTS, or other DEVELOPMENT, including FILL, shall be
permitted within Zones A1-30 and AE on the COUNTY'S FIRM, unless it is demonstrated
that the cumulative effect of the proposed DEVELOPMENT, when combined with all other
existing and anticipated DEVELOPMENT, will not increase the WATER SURFACE
ELEVATION of the BASE FLOOD more than half a foot ( six (6) inches) at any point within
the COUNTY.
B. Per 44CFR 60.3(c), all new MANUFACTURED HOMES that are placed within Zones
Al -A30, AH, and AE that are outside of a MANUFACTURED HOME PARK OR

be securely anchored to an adequately anchored foundation system to resist flotation,
collapse, and lateral movement.
C. Per 44CFR 60.3(c), existing MANUFACTURED HOMES that are placed or
SUBSTANTIALLY IMPROVED on sites in an existing MANUFACTURED HOME PARK
OR SUBDIVISION within Zones Al through A30, AH, and AE, and that are not subject to
the provisions of the above Subsection B, shall be elevated so that either:
1. The LOWEST FLOOR of the MANUFACTURED HOME is a minimum of one foot
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.
D. Per 44CFR 60.3(c), RECREATIONAL VEHICLES placed on sites within the
FLOODPLAIN shall:
1. Be on site for fewer than one -hundred eighty (180) consecutive days and be fully
licensed and properly equipped for highway usage; or
2. Shall meet the elevation and anchoring requirements for MANUFACTURED HOMES.
A RECREATIONAL VEHICLE is properly equipped for highway usage if it is on its wheels
or jacking system, is attached to the site only by quick disconnect utilities and security
devices, and has no permanently attached additions.
E. Per 44CFR 60.3(c), Zone AO (shallow flooding) areas can be located within the SPECIAL
FLOOD HAZARD AREA. These SPECIAL FLOOD HAZARD AREAS are 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 where velocity flow may be
evident. Such FLOODING is characterized by ponding or sheet flow. The following
provisions shall apply:
1. All NEW CONSTRUCTION and SUBSTANTIAL IMPROVEMENTS of residential
STRUCTURES shall have the LOWEST FLOOR (including BASEMENT or
crawlspace) ELEVATED above the HIGHEST ADJACENT GRADE at least one foot
above the depth number specified in feet on the FIRM. If no depth number is
provided on the FIRM, the LOWEST FLOOR (including BASEMENT or crawlspace)
shall be a minimum of three (3) feet above the HIGHEST ADJACENT GRADE. Upon
completion of the STRUCTURE, the elevation of the LOWEST FLOOR, including the
BASEMENT or crawlspace, shall be certified by a registered Colorado Land Surveyor.
Such certification shall be submitted to the FLOODPLAIN ADMINISTRATOR.
2. With the exception of CRITICAL FACILITIES, all NEW CONSTRUCTION or
SUBSTANTIAL IMPROVEMENT of any commercial, industrial, or other
non-residential STRUCTURES shall either have the lowest floor (including
BASEMENT or crawlspace) ELEVATED a minimum of one foot above the BASE

together with attendant utility and sanitary facilities, be designed so that at one foot
above 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 the effects of
buoyancy. A registered professional engineer or architect licensed in the State of
Colorado shall develop and/or review the 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.
3. Adequate drainage paths shall be established to guide FLOOD waters around and
away from proposed STRUCTURES.
F. Per 44CFR 60.3(c), notwithstanding any other provisions of this ORDINANCE, the
COUNTY may approve certain development in Zones A1-30, AE, or AH, on the
COUNTY'S FIRM which results in the increase of the BASE FLOOD WATER SURFACE
ELEVATION by more than one-half foot (six (6) inches), provided that a CLOMR is
submitted to FEMA which fulfills the provisions of 44CFR 65.12 and receives FEMA
approval.
Sec. 23-11-390. Specific standards for FLOODPLAINS with FLOODWAYS.
FLOODWAYS are administrative limits and tools used to regulate existing and future
FLOODPLAIN DEVELOPMENT. The State of Colorado has adopted FLOODWAY standards
that are more stringent than the FEMA minimum standard. Located within the SPECIAL FLOOD
HAZARD AREA are areas designated as FLOODWAY. Since the FLOODWAY is extremely
hazardous due to the velocity of FLOOD waters which carry debris, potential projectiles and
erosion potential, the following provisions, in addition to the provisions of the general standards in
Section 23-11-360, specific standards for Approximate Floodplains in Section 23-11-370, and
specific standards for FLOODPLAINS with BASE FLOOD ELEVATIONS in Section 23-11-380,
for all NEW CONSTRUCTION and SUBSTANTIAL IMPROVEMENTS that are located in
FLOODWAYS shall apply:
A. Per 44CFR 60.3(d), encroachments within the regulatory FLOODWAY are prohibited,
including FILL, NEW CONSTRUCTION, SUBSTANTIAL IMPROVEMENTS, and other
DEVELOPMENT unless it has been demonstrated through hydrologic and hydraulic
analyses performed by a licensed Colorado Professional Engineer and in accordance with
standard engineering practices that the proposed encroachment would not result in any
increase, as shown by a NO RISE CERTIFICATION, in FLOOD levels within the COUNTY
during the occurrence of the BASE FLOOD discharge. Per CWCB FLOODPLAIN Rule 7,
FEMA's Guidelines and Specifications for Flood Hazard Mapping Partners and any other
FEMA accepted methodology are considered to be standard engineering practices.
B. Per 44CFR 60.3(d), if the above standard is satisfied, all NEW CONSTRUCTION and
SUBSTANTIAL IMPROVEMENTS shall comply with all applicable provisions of this
ORDINANCE.
C. Per 44CFR 60.3(d), notwithstanding any other provisions of this ORDINANCE, the
COUNTY may approve certain development in Zones Al through 30, AE, or AH, on the
COUNTY'S FIRM which results in the increase of the BASE FLOOD WATER SURFACE
ELEVATION by more than one-half foot (six (6) inches), provided that a CLOMR is

Sec. 23-11-400. Specific standards for FLOODPLAIN Studies.
CWCB FLOODPLAIN Rules 7, 9, and 10 provide specific standards for conducting
FLOODPLAIN studies.
A. Per CWCB FLOODPLAIN Rule 7, all FLOODPLAIN studies shall be carried out in
accordance with the following standards:
1. Approximate FLOODPLAIN information shall be based on detailed hydrology
computed for 100 -YEAR FLOODS. Hydraulic information shall be produced using
approximate, field, or limited techniques and the best available topographic/survey
data.
2. Detailed FLOODPLAIN information shall be based on detailed hydrologic and
hydraulic determinations for 100 -YEAR FLOODS. FLOOD profiles and
FLOODPLAIN delineations for the BASE FLOOD shall be plotted.
3. Base mapping for FLOODPLAIN studies shall meet the minimum standards as set
forth in FEMA's Guidelines and Specifications for Flood Hazard Mapping Partners.
4. Topographic and field survey information for FLOODPLAIN studies shall meet the
minimum standards as set forth in FEMA's Guidelines and Specifications for Flood
Hazard Mapping Partners.
5. Geographic Information System information for FLOODPLAIN studies shall meet the
minimum standards as set forth in FEMA's Guidelines and Specifications for Flood
Hazard Mapping Partners.
6. Hydrologic analyses for FLOODPLAIN studies shall be completed using the
information set forth in FEMA's Guidelines and Specifications for Flood Hazard
Mapping Partners. Additionally, hydrology studies must comply with the following:
a. All FLOODPLAIN studies, regardless of the level of detail, shall utilize detailed
hydrologic information. The Colorado Floodplain and Stormwater Criteria Manual
may be used as a reference to aid in the analysis; and
b. Any new study to evaluate hydrologic information and/or design storm criteria shall
be completed in such a way that it is scientifically defensible and technically
reproducible.
7. Hydraulic analyses for FLOODPLAIN studies shall be completed using the protocols
set forth in FEMA's Guidelines and Specifications for Flood Hazard Mapping Partners.
8. FLOODPLAIN delineations shall be completed using the protocols set forth in FEMA's
Guidelines and Specifications for Flood Hazard Mapping Partners and shall, at a
minimum, comply with the technical quality assurance standards as follows:

a. The FLOOD elevations and the FLOODPLAIN delineations on the maps must
correlate reasonably to the best available topographic information for the stream
and adjacent corridor.
b. The planimetric features on the FLOODPLAIN maps must be consistent with the
best available aerial photographs or other suitable information for the stream and
adjacent corridor, as determined through prevailing industry practices.
9. The results of the hydrologic analyses, hydraulic analyses, and FLOODPLAIN
delineations shall be summarized in a written report. All FLOODPLAIN information
that is presented for designation shall be properly titled, dated, organized, and bound
as a stand-alone document. In addition to the hard copy final report, a digital copy of
the final report shall be submitted in MS WORD and PDF formats. All pertinent
backup data such as GIS files, hydrologic models, and hydraulic models shall also be
provided in acceptable digital formats.
a. The regulatory FLOODPLAIN maps shall show at a minimum the flood boundaries,
the location of all cross sections used in the hydraulic analysis, the reference line
drawn down the center of the FLOODPLAIN or low flow CHANNEL, and a
sufficient number of FLOOD contours in order to reconstruct the floodwater
surface profiles.
b. FLOOD contours or BASE FLOOD ELEVATIONS shall be shown as wavy lines
drawn perpendicular to the direction of flow of floodwater and shall extend
completely across the area of the mapped regulatory FLOODPLAIN.
c. The regulatory FLOODPLAIN map scale shall be 1 -inch equals 1,000 feet or such
map scale showing greater detail. FEMA map panels may be at 1 -inch equals
500 ft, 1 -inch equals 1,000 feet, or 1 -inch equals 2,000 feet.
B. Per CWCB FLOODPLAIN Rule 9, if a publicly operated and maintained STRUCTURE is
specifically designed and operated either in whole or in part for FLOOD control purposes,
then its effects shall be taken into consideration when delineating the FLOODPLAIN
below such STRUCTURE.
1. The effects of the STRUCTURE shall be based upon the 100 -YEAR FLOOD with full
credit given to the diminution of peak FLOOD discharges, which would result from
normal FLOOD control STRUCTURE operating procedures.
2. The hydrologic analysis shall consider the effects of on -site detention for rooftops,
parking lots, highways, road FILLS, railroad embankments, diversion STRUCTURES,
refuse embankments, including, but not limited to, solid waste disposal facilities, mill
tailings, impoundments, siltation ponds, livestock water tanks, erosion control
structures, or other STRUCTURES, only if they have been designed and constructed
with the purpose of impounding water for FLOOD detention and are publicly operated
and maintained. Public operation and maintenance shall include direct responsibility
or ultimate responsibility through written agreement.

3. Detention STRUCTURES that are privately operated or maintained shall not be
included in the hydrologic analysis unless it can be shown that they exacerbate
downstream peak discharges.
4. If a STRUCTURE is not specifically designed and operated, either in whole or in part,
for FLOOD control purposes (i.e. railroad embankments, roadway embankments,
non -engineered berms, etc.), then its effects shall not be taken into account and the
delineation of the FLOODPLAIN below such STRUCTURE shall be based upon the
100 -YEAR FLOOD that could occur absent the STRUCTURE'S influence. However, if
adequate assurances have been obtained to preserve the FLOOD routing capabilities
of such STRUCTURE, then the delineation of the FLOODPLAIN below the structure
may be based on the assumption that the reservoir formed by the STRUCTURE will be
filled to the elevation of the STRUCTURE'S emergency spillway and the 100 -YEAR
hydrology can be routed through the reservoir to account for any FLOOD attenuation
effects.
5. Adequate assurances shall include appropriate recognition in a COUNTY adopted
master plan of:
a. FLOOD routing capability of the reservoir, as shown by comparison of the
100 -YEAR FLOODPLAIN in plan and profile with and without the STRUCTURE in
place, in order that the public may be made aware of the potential change in level
of FLOOD protection in the event that the reservoir FLOOD routing capability is
lost;
b. The need to preserve that FLOOD routing capability by whatever means available
in the event that the reservoir owners attempt to make changes that would
decrease the FLOOD routing capability; and
c. A complete operations and maintenance plan.
6. Irrigation facilities, including, but not limited to, ditches and canals, may be used as
stormwater or FLOOD conveyance facilities, if approved by the irrigation facility
owners.
7. Unless specified otherwise by aforementioned written agreement, FLOOD hydrology
for FLOODPLAIN mapping purposes shall consist of peak hydrologic flows that are
identical immediately downstream and immediately upstream of a ditch or canal that is
generally perpendicular to the stream or drainageway of interest. The irrigation
facility shall be assumed as running full so that there are no computed FLOOD
reduction benefits downstream of the irrigation facility. Backwater behind irrigation
facilities shall be mapped.
C. Per CWCB FLOODPLAIN Rule 10, the use of LEVEES for property protection, FLOOD
control, and FLOOD hazard mitigation is not encouraged unless other mitigation
alternatives are not viable.
1. The areas landward of an accredited LEVEE SYSTEM shall be mapped as Zone X
(shaded). The FIRM for these areas will include an informational note that advises
users of the FLOOD risk in LEVEE -impacted areas.

2. In situations where LEVEES are the only viable alternative for protection of existing
DEVELOPMENT, "setback" LEVEES shall be designed and constructed to maintain
the natural CHANNEL and reserve a portion of the natural FLOODPLAIN capacity.
3. LEVEES shall not be used for FLOOD protection along streams or WATERCOURSES
where new DEVELOPMENT is planned.
4. LEVEES may be used to protect public utility plant facilities for wastewater treatment
and pumping as well as electric power plants due to their close proximity to natural
waterways.
5. For existing LEVEES that protect existing DEVELOPMENT, proper maintenance shall
be performed by LEVEE owners/operators, or non-federal sponsors in the case of
federal LEVEES, according to an operations and maintenance plan. LEVEES shall
not be constructed for the primary purpose of removing undeveloped lands from
mapped FLOODPLAIN areas for the purposes of DEVELOPMENT. When
constructed, LEVEES for which protection will be considered for designation and
approval must meet the requirements set forth in 44 CFR 65.10. Artificial
embankments that function as a LEVEE or a FLOOD control STRUCTURE must meet
the provisions of CWCB Rule 10 or 2CCR 402-1 (2010), respectively, in order to be
considered as providing protection.
6. An operation and maintenance manual that ensures continuing proper function of the
LEVEE shall be prepared and updated. The LEVEE shall be structurally sound and
adequately maintained. Sedimentation effects shall be considered for all LEVEE
projects. Certification from a Federal or State agency or a Colorado registered
professional engineer that the LEVEE meets the minimum freeboard criteria stated
above and that it appears, on visual inspection, to be structurally sound and
adequately maintained shall be required on a three-year basis and provided to the
CWCB. LEVEES that have obvious structural defects or that are obviously lacking in
proper maintenance shall not be considered in the hydraulic analysis.
7. Privately -operated or maintained LEVEE SYSTEMS will not be considered in the
hydraulic analysis performed unless the COUNTY mandates operation and
maintenance of the LEVEE SYSTEM and the criteria set forth below are met.
a. LEVEES for which the community, State, or Federal government has responsibility
for operations and maintenance will be considered, provided that the criteria set
forth below are met.
b. Privately -owned LEVEE SYSTEMS shall only be considered in the hydraulic
analysis if a fully executed agreement exists between the LEVEE owner and a
governmental entity enabling unrestricted access to the governmental entity for
the purposes of inspection and maintenance and gives the governmental entity
responsibility for maintenance.
c. A copy of the executed agreement shall be provided to the CWCB and the CWCB
shall be notified in writing of any changes made to the agreement.

8. A minimum LEVEE freeboard of three (3) feet shall be necessary with an additional
1 -foot of freeboard within 100 feet of either side of hydraulic structures within the
LEVEE or wherever the flow is constricted such as at bridges. An additional 0.5 -foot
above this minimum is also required at the upstream end of the LEVEE.
9. In cases where levees are mapped as providing 100 -YEAR FLOOD protection the
adequacy of interior drainage systems, on the landward side of the LEVEE, shall be
evaluated. Areas subject to FLOODING from inadequate interior drainage behind
LEVEES shall be mapped using standard procedures.
10. Evaluation of LEVEES shall not consider human intervention (e.g., capping of levees
by sandbagging, earth fill, or flashboards) for the purpose of increasing a LEVEE'S
design level of protection during an imminent FLOOD. Human intervention shall only
be considered for the operation of closure structures (e.g., gates or stop logs) in a
LEVEE SYSTEM designed to provide at least the level of BASE FLOOD protection,
including adequate freeboard as described above, provided that such human
operation is specifically included in an emergency response plan adopted by the
COUNTY.
11. For areas protected by a LEVEE providing less than the level of BASE FLOOD
protection, FLOOD elevations shall be computed as if the LEVEE did not exist. For the
unprotected area between the LEVEE and the source of FLOODING, the elevations to
be shown shall be obtained from either the FLOOD profile that would exist at the time
LEVEE overtopping begins or the profile computed as if the LEVEE did not exist,
whichever is higher. This procedure recognizes the increase in FLOOD elevation in
the unprotected area that is caused by the LEVEE itself. This procedure may result in
FLOOD elevations being shown as several feet higher on one side of the levee than on
the other. Both profiles shall be shown in the final report and labeled as "before LEVEE
overtopping" and "after LEVEE overtopping" respectively.

within the FLOODPLAIN or FLOODWAY.
b. Per 44CFR 60.6, a VARIANCE request of the terms of this ORDINANCE within the
FLOOODPLAIN or FLOODWAY shall not be granted until and unless the Board of
County Commissioners has found and determined that:
1. The VARIANCE is the minimum VARIANCE necessary, considering the
FLOOD hazard, to afford relief;
2. A showing of good and sufficient cause has been demonstrated by the party
requesting the VARIANCE;
3. Failure to grant the VARIANCE would result in exceptional hardship to the
party requesting the VARIANCE;
4. A VARIANCE granted for a property in the FLOODWAY would not result in any
increase in FLOOD levels during the BASE FLOOD discharge;
5. The granting of a VARIANCE will not result in any increased FLOOD heights
during a 100 -YEAR FLOOD event, additional threats to public safety or
extraordinary public expense, the creation of nuisances, fraud or victimization
of the public, or conflict with existing local laws or regulations.
6. VARIANCES may be granted for one or more of the following reasons:
i. VARIANCES may be granted for NEW CONSTRUCTION and
SUBSTANTIAL IMPROVEMENTS to be erected on a LOT of one-half ('h)
acre or less in size contiguous to and surrounded by LOTS with existing
STRUCTURES constructed below the base level, provided that the
material required has been fully considered. As the LOT size increases
beyond one-half ('/) acre, the technical justifications required for issuing
the VARIANCE will increase;
H. VARIANCES may be granted 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 above;
iii. VARIANCES may be granted for NEW CONSTRUCTION, SUBSTANTIAL
IMPROVEMENTS, and other DEVELOPMENT necessary for the
conduction of a functionally dependent USE provided that:
a) All the criteria listed above is met, and
b) The STRUCTURE or other DEVELOPMENT is protected by methods
that minimize FLOOD damages during the BASE FLOOD and create
no additional threats to public safety.
