Exceptional hardship means, for the purpose of variances from this Ordinance or the
Building Code, the exceptional difficulty that would result from a failure to grant a requested
variance. Mere economic or financial hardship is not exceptional. Inconvenience, aesthetic
considerations, physical handicaps, personal preferences, or the disapproval of one's neighbors
do not, as a rule, qualify as exceptional hardships. All of these circumstances can be resolved
through other means without granting variances, even when the alternatives are more
expensive or require the property owner to build elsewhere or put the parcel to a different use
than originally intended.

the applicant satisfies the FEMA requirements for issuance of a Letter of Map Revision.
DIVISION 7. INSPECTIONS
Sec. 29.90.170. Inspections, in general.
Development for which a permit for floodplain development is required shall be subject
to inspection.Approval as a result of an inspection shall not be construed to be an approval of a
violation of the provisions of this Ordinance or the Building Code. Inspections presuming to give
authority to violate or cancel the provisions of this Ordinance or the Building Code or other
ordinances shall not be valid.
Sec. 29.90.175. Inspections of development other than buildings and structures.
The Floodplain Administrator shall make or cause to be made, inspections of all
development other than buildings and structures that is authorized by issuance of a permit for
floodplain development under this Ordinance. The Floodplain Administrator shall inspect flood
hazard areas from time to time to determine when development is undertaken without
issuance of a permit.
Sec. 29.90.180. Inspections of manufactured homes installations.
The Floodplain Administrator shall make or cause to be made, inspections of installation
and replacement of manufactured homes in flood hazard areas authorized by issuance of a

required in the Building Code shall be prepared by a CA Licensed Land Surveyor or
Civil Engineer and submitted to the Building Official.
(2) Final inspection. Prior to the final inspection, certification of the elevation required
in the Building Code shall be prepared by a CA Licensed Land Surveyor or Civil
Engineer and submitted to the Building Official.
DIVISION 8. VARIANCES
Sec. 29.90.190. Nature of variances.
The considerations and conditions for variances set forth in this article are based on the
general principle of zoning law that variances pertain to a piece of property and are not
personal in nature. A variance may be issued for a parcel of property with physical
characteristics so unusual that complying with the requirements of this Ordinance would create
an exceptional hardship to the applicant or the surrounding property owners. The
characteristics must be unique to the property and not be shared by adjacent parcels. The
unique characteristic must pertain to the land itself, not to the structure, its inhabitants, or the
property owners. The issuance of a variance is for floodplain management purposes only.
Federal flood insurance premium rates are determined by the NFIP according to actuarial risk
and will not be modified by the granting of a variance.
It is the duty of the Town Council of Los Gatos to promote public health, safety, and
welfare and minimize losses from flooding. This duty is so compelling and the implications of
property damage and the cost of insuring a structure built below flood level are so serious that
variances from the elevation or other requirements in the Building Codes should be quite rare.
The long term goal of preventing and reducing flood loss and damage, and minimizing recovery
costs, inconvenience, danger, and suffering, can only be met when variances are strictly limited.
Therefore,the variance requirements in this Ordinance are detailed and contain multiple
provisions that must be met before a variance can be properly issued. The criteria are designed
to screen out those situations in which alternatives other than a variance are more appropriate.
Sec. 29.90.195.Variances;general.
The Planning Commission shall hear and decide requests for variances from the strict
application of this Ordinance.
Sec. 29.90.200. Limitations on authority.
The Planning Commission shall base its determination on technical justifications
submitted by applicants, the considerations and conditions set forth in this article, the
comments and recommendations of the Floodplain Administrator and Building Official, as
applicable, and has the right to attach such conditions to variances as it deems necessary to
21 of 34
Ordinance 2378 November 4,2025
further the purposes and objectives of this Ordinance and the Building Code.
22 of 34
Ordinance 2378 November 4, 2025
Sec. 29.90.205. Records.
The Floodplain Administrator shall maintain a permanent record of all variance actions,
including justification for issuance.
Sec. 29.90.210. Historic structures.
A variance is authorized to be issued for the repair, improvement, or rehabilitation of a
historic structure upon a determination that the proposed repair, improvement, 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. When the proposed work precludes the structure's continued designation as a
historic building, a variance shall not be granted and the structure and any repair,
improvement, and rehabilitation shall be subject to the requirements of the Building Code.
Sec. 29.90.215. Restrictions in floodways.
A variance shall not be issued for any proposed development in a floodway when any
increase in flood levels would result during the base flood discharge, as evidenced by the
applicable analyses required in Section 29.90.160(1) of this Ordinance.
Sec. 29.90.220. Functionally dependent uses.
A variance is authorized to be issued for the construction or substantial improvement
necessary for the conduct of a functionally dependent use provided the criteria in Section 1612
of the Building Code (CCR Title 24 Part 2) or Section R322 of the Residential Code (CCR Title 24
Part 2.5) are met, as applicable, and the variance is the minimum necessary to allow the
construction or substantial improvement, and that all due consideration has been given to use
of methods and materials that minimize flood damages during the base flood and create no
additional threats to public safety.
Sec. 29.90.225. Considerations for issuance of variances.
In reviewing applications for variances, all technical evaluations, all relevant factors, all
other requirements of this Ordinance and the Building Code, as applicable, and the following
shall be considered:
(1) The danger that materials and debris may be swept onto other lands resulting in
further injury or damage.
(2) The danger to life and property due to flooding or erosion damage.
(3) The susceptibility of the proposed development, including contents,to flood
damage and the effect of such damage on current and future owners.
(4) The importance of the services provided by the proposed development to the
23 of 34
Ordinance 2378 November 4, 2025
Town.
(5) The availability of alternate locations for the proposed development that are not
subject to flooding or erosion and the necessity of a waterfront location, where
applicable.
(6) The compatibility of the proposed development with existing and anticipated
development.
(7) The relationship of the proposed development to the comprehensive plan and
floodplain management program for that area.
(8) The safety of access to the property in times of flood for ordinary and emergency
vehicles.
(9) The expected heights, velocity, duration, rate of rise, and debris and sediment
transport of the floodwater and the effects of wave action, if applicable, expected
at the site.
(10) 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, streets, and bridges.
Sec. 29.90.230. Conditions for issuance of variances.
Variances shall only be issued upon:
(1) Submission by the applicant of a showing of good and sufficient cause that the
unique characteristics of the size, configuration, or topography of the site limit
compliance with any provision of this Ordinance or renders the elevation standards
of the Building Code inappropriate.
(2) A determination that failure to grant the variance would result in exceptional
hardship due to the physical characteristics of the land that render the lot
undevelopable.
(3) A determination that the granting of a variance will not result in increased flood
heights, additional threats to public safety, extraordinary public expense, nor create
nuisances, cause fraud on or victimization of the public or future property owners,
or conflict with existing local laws or ordinances.
(4) A determination that the variance is the minimum necessary, considering the flood
hazard,to afford relief.
(5) When the request is to allow construction of the lowest floor of a new building or
substantial improvement of a building below the base flood elevation, notification
to the applicant in writing with the signature of the Floodplain Administrator
specifying the difference between the base flood elevation and the proposed
elevation of the lowest floor, stating that issuance of a variance to construct below
the elevation required in the Building Code will result in increased premium rates
for federal flood insurance up to amounts as high as $25 for$100 of insurance
coverage, and that such construction below the required elevation increases risks
to life and property.

DIVISION 9. VIOLATIONS
Sec. 29.90.235.Violations.
Any development in any flood hazard area that is being performed without an issued
permit or that is in conflict with an issued permit shall be deemed a violation. A building or
structure without the documentation of the elevation of the lowest floor, other required design
certifications, or other evidence of compliance required by this Ordinance or the Building Code,
is presumed to be a violation until such time as required documentation is submitted. Violation
of the requirements shall constitute either an infraction, misdemeanor, or be subject to a civil
penalty at the Floodplain Administrators decision.

DIVISION 16. FLOOD CONTROL PROJECTS
Sec. 29.90.390. Flood control projects;general.
In addition to applicable federal, state, and other local permits, a permit for floodplain
development is required for construction of flood control projects. The purpose for the permit
is to examine the impact on flood hazard areas,floodways, and base flood elevations shown on
the FIRM. Unless otherwise authorized by separate regulations, issuance of this permit does
not address the sufficiency of the structural elements of the proposed flood control project.
Permits for floodplain development and building permits in areas affected by proposed flood
control projects shall not be issued based on CLOMR issued by FEMA.
Sec. 29.90.395. Flood control projects; applications.
32 of 34
Ordinance 2378 November 4,2025
Applications for permits for flood control projects shall include documentation
including, but not limited to:
(1) Site plan or document showing the existing topography and the boundaries of the
flood hazard areas, floodway boundaries, and base flood elevations shown on the
FIRM.
(2) Site plan or document showing the proposed topography and the proposed
changes to the boundaries of the flood hazard areas, floodway boundaries, and
base flood elevations.
(3) The documentation submitted to FEMA for a CLOMR and, if issued,the Conditional
Letter of Map Revision. Submittal requirements and processing fees shall be the
responsibility of the applicant. A CLOMR is required when a proposed flood control
project alters a floodway and increases base flood elevations more than greater
than 0.00 feet, or alters a watercourse a riverine flood hazard area for which base
flood elevations are included in the Flood Insurance Study or on the FIRM and
floodways have not been designated and increases base flood elevations more than
1.0 foot.
SECTION III. Warning.
The degree of flood protection required by this Ordinance and the Building Codes is
considered reasonable for regulatory purposes and is based on scientific and engineering
considerations. Larger floods can and will occur. Flood heights may be increased by man-made or
natural causes. Enforcement of this Ordinance and the Building Codes does not imply that land
outside the special flood hazard areas,or that uses permitted within such flood hazard areas,will
be free from flooding or flood damage.The flood hazard areas and base flood elevations contained
in the FIS and shown on FIRMs and the requirements of Title 44 Code of Federal Regulations,
Sections 59 and 60 may be revised by the FEMA, requiring the Town to revise this Ordinance to
remain eligible for participation in the NFIP. No guaranty of vested use, existing use, or future
use is implied or expressed by compliance with this Ordinance.
SECTION IV. Severability.
In the event that a court of competent jurisdiction holds any Section, subsection,
paragraph, sentence, clause, or phrase in this Ordinance unconstitutional, preempted, or
otherwise invalid, the invalid portion shall be severed from this Section and shall not affect the
validity of the remaining portions of this Section. The Town hereby declares that it would have
adopted each Section, subsection, paragraph, sentence, clause, or phrase in this Section
irrespective of the fact that any one or more Sections, subsections, paragraphs, sentences,
clauses, or phrases in this Section might be declared unconstitutional, preempted, or otherwise
invalid.
