BEING A RESOLUTION OF THE PLANNING COMMISSION OF
THE CITY OF CAMPBELL RECOMMENDING THAT THE CITY
COUNCIL APPROVE A CITY-INITIATED TEXT AMENDMENT
(PLN2009-24) TO UPDATE CAMPBELL MUNICIPAL CODE
SECTION 21.22 (FLOOD DAMAGE PREVENTION) TO COMPLY
WITH CURRENT FEMA (FEDERAL EMERGENCY MANAGEMENT
AGENCY) STANDARDS.
After notification and public hearing as specified by law on the proposed City of
Campbell Text Amendments Update, and after presentation by the Community
Development Director, proponents and opponents, the Planning Commission did
determine that the adoption of the proposed Text Amendments based upon the
following findings.
The Planning Commission finds as follows with regard to File No. PLN2009-24:
1. The legislature of the State of California has, in Government Code Sections 65302,
65560 and 65800, conferred upon local government units authority to adopt
regulations designed to promote the public health, safety and general welfare of its
citizenry;
2. The City of Campbell recognizes the importance of promoting the public health,
safety and general welfare, and minimizing public and private losses due to flood
conditions in specific areas of the City; and,
3. As the City of Campbell participates in the National Flood Insurance Program,
Federal regulations require that the City revise the existing floodplain management
regulations to meet the minimum standards set forth by FEMA under the National
Flood Insurance Act of 1968.
Based upon the foregoing findings of fact, the Planning Commission further finds and
concludes that:
1. The proposed Zoning Code text amendment is consistent with the goals, polices,
and actions of the General Plan;
2. The proposed Zoning Code text amendment is internally consistent with other
applicable provisions of the Zoning Code; and,
3. The proposed Zoning Code text amendment would not be detrimental to the public
interest, health, safety, convenience, or general welfare of the city.

be constructed, located, extended, converted, or altered without full compliance with
the terms of this chapter and other applicable regulations.
D. Abrogation and greater restrictions. The regulations in this chapter are not
intended to repeal, abrogate, or impair any existing easements, covenants, or deed
restrictions. However, where the regulations in this chapter and another ordinance,
easement, covenant, or deed restriction conflict or overlap, whichever imposes the
more stringent regulations shall prevail.
E. Interpretation. In the interpretation and application of this chapter, all
provisions shall be:
1. Considered as minimum requirements;
2. Liberally construed in favor of the governing body; and
3. Deemed neither to limit nor repeal any other powers granted under State
statutes.
F. 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 considerations. 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 hazards, or uses allowed within these
areas, will be free from flooding or flood damages. This chapter shall not create liability
on the part of the city, any officer or employee thereof, or the Federal Insurance
Administration, for any flood damages that result from reliance on this chapter or any
administrative decision lawfully made there under.
G. Severability. This ordinance and the various parts thereof are hereby
declared to be severable. Should any sections of this ordinance be declared by
the courts to be unconstitutional or invalid, such decision shall not effect the
validity of the ordinance as a whole, or any portion thereof other than the section
so declared to be unconstitutional or invalid.
21.22.040 Administration. A. Establishment of development permit. A zoning
clearance, in compliance with Chapter 21.40, shall be obtained before construction or
development begins within any area of special flood hazards established in Subsection
21.22.030(6). Application for a zoning clearance shall be made on forms furnished by
the community development department, and may include, but not be limited to, plans
in duplicate drawn to scale showing the nature, location, dimensions, and elevations of
the area in question; and existing or proposed structures, fill, storage of materials,
drainage facilities. Specifically, the following information is required:
1. Proposed elevation in relation to mean sea level of the lowest floor
(including basement) of all structures;
2. Proposed elevation in relation to mean sea level to which any structure
will be floodproofed;
3. All appropriate certifications listed in Subsection (C)(4), below; and
4. Description of the extent to which any watercourse will be altered or
relocated as a result of proposed development.
Exhibit A
Page 7 of 12
B. Designation of the floodplain administrator. The community development
director is hereby appointed to administer and implement this chapter by allowing or
denying development requests in compliance with its provisions.
C. Duties and responsibilities of the floodplain administrator. The duties and
responsibilities of the floodplain administrator shall include, but not be limited to:
1. Permit review:
a. Review all development requests to determine that the permit
requirements of this chapter have been satisfied;
b. Determine that all other required State and federal permits have
been obtained;
c. Determine that the site is reasonably safe from flooding;
d. Determine that the proposed development does not adversely
affect the carrying capacity of areas where base flood elevations have been
determined but a floodway has not been designated. For purposes of this chapter,
"adversely affects" means 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 one foot at any point.
2. Development of substantial improvement and substantial damage
procedures:
a. Using FEMA publication FEMA 213, "Answers to Questions
About Substantially Damaged Buildings," develop detailed
procedures for identifying and administering requirements for
substantial improvement and substantial damage, to include
defining "Market Value."
b. Assure procedures are coordinated with other
departments/divisions and implemented by community staff.
2. Use of other base flood data. When base flood elevation data has not
been provided in compliance with Subsection 21.22.030(8) (Areas of special flood
hazard), above, the floodplain administrator shall obtain, review and reasonably utilize
any base flood elevation and floodway data available from a Federal, State or other
source, in order to administer Section 21.22.050 (Provisions for flood hazard
reduction), below. Any information shall be submitted to the city council for adoption.
3. :Notification of
other Agencies.
a. Alteration or relocation of a watercourse:
a-1. Notify adjacent communities and the California Department of
Resources prior to such alteration or relocation of a watercourse, and submit evidence
of such notification to the Federal Insurance Administration;
b-2.
. Submit evidence of such
notification to the Federal Emergency management Agency; and,
s-3. Assure that the flood carrying capacity within the altered
or relocated portion of said watercourse is maintained.
b. Base Flood Elevation changes due to physical alterations:
1. Within 6 months of information becoming available or
proiect completion, whichever comes first the floodplain administer shall submit
Exhibit A
Page 8 of 12
or assure that the permit applicant submits technical or scientific data to FEMA
for a Letter of Map Revision (LOMR).
2. All LOMR's for flood control projects are approved prior to
the issuance of building permits. Building permits must not be issued based on
Conditional Letters of Map Revision (CLOMR's). Approved CLOMR's allow
construction of the proposed flood control project and land preparation as
specified in the "start of construction" definition.
Such submissions are necessary so that upon confirmation of
those physical chanaes to flooding conditions, risk premium rates and
floodplain management requirements are based on current data.
c. Changes corporate boundaries:
1. Notify FEMA in writing whenever the corporate boundaries
have been modified by annexation or other means and include a copy of the amp
of the community clearly delineating the new corporate limits.
4. Obtain and maintain for public inspection and make available as needed:
a. The certification required in Subsection 21.22.050(A)(3)(a)(floor
elevations);
b. The certification required in Subsection 21.22.050(A)(3)(b)(1)
(elevation or flood proofing of nonresidential structures);
c. The certification required in subsection 21.22.050(A)(3)(c)(1) or
21.22.050(A)(3)(c)(2) (wet flood proofing standard);
d. The certified elevation required in Subsection 21.22.050(C)(2)
(subdivision standards);
e. The certification required in Subsection 21.22.050(E) (Floodway
Encroachments).
5. Make interpretations, where needed, as to the exact location of the
boundaries of the areas of special flood hazards (for example, where there appears to
be a conflict between a mapped boundary and actual field conditions). The person
contesting the location of the boundary shall be given a reasonable opportunity to
appeal the interpretation, as provided in Section 21.22.060.
6. Take action to remedy violations of this chapter as specified in
Subsection 21.22.030(C).
21.22.050 Provisions for flood hazard reduction. A. Standards of construction.
In all areas of special flood hazard, the following standards are required:
1. Anchoring.
a. All new construction and substantial improvements shall be
anchored to prevent flotation, collapse, or lateral movement of the structure resulting
from hydrodynamic and hydrostatic loads, including the effects of buoyancy.
b. All manufactured homes shall meet the anchoring standards of
paragraph D, (Standards for manufactured homes), below.
2. Construction materials and methods.

Exhibit A
Page 9 of 72
c. All new construction and substantial improvements shall be
constructed with electrical, heating, ventilation, plumbing, and air-conditioning
equipment and other service facilities that are designed and/or located so as to prevent
water from entering or accumulating within the components during conditions of
flooding.
d. A breakaway wall shall have a safe design loading resistance of not
less than 10 pounds or no more than 20 pounds per square foot. Use of breakaway
walls shall be certified by a registered engineer or architect and shall meet the following
conditions:
(1) Breakaway wall collapse shall result from a water load less
than that which would occur during the base flood; and
(2) The elevated portion of the building shall not incur any
structural damage due to the effects of wind and water loads acting simultaneously in
the event of the base flood.
3. Elevation and flood proofing.
a. New construction and substantial improvement of any structure
shall have the lowest floor, including basement, elevated to or above base flood
elevation. Nonresidential structures may meet the standards in Subsection (A)(3)(c),
below. Upon completion of the structure, the elevation of the lowest floor, including
basement, shall be certified by a registered professional engineer or surveyor, or
verified by the Building Inspector to be properly elevated. Such certification or
verification shall be provided to the floodplain administrator.
b. Nonresidential construction shall either be elevated in conformance
with Subsection (A)(3)(a), above, or together with attendant utility and sanitary facilities:
(1) Be flood proofed so that below the base flood level the
structure is watertight, with walls substantially impermeable to the passage of water;
(2) Have structural components capable of resisting
hydrostatic and hydrodynamic loads and effects of buoyancy; and
(3) Be certified by a registered professional engineer or architect
that the standards of this subsection are satisfied. Such certifications shall be provided
to the floodplain administrator.
c. Require, for all new construction and substantial improvements, that
fully enclosed areas below the lowest floor that are subject to flooding shall be
designed to automatically equalize hydrostatic flood forces on exterior walls by allowing
for the entry and exit of floodwaters. Designs for meeting this requirement shall either
be certified by a registered professional engineer or architect or meet or exceed the
following minimum criteria:
(1) Either a minimum of two openings having a total net area of
not less than one square inch for every square foot of enclosed area subject to flooding
shall be provided; the bottom of all openings shall be no higher than one foot above
grade. Openings may be equipped with screens, louvers, valves or other coverings or
devices provided that they permit the automatic entry and exit of floodwaters; or
(2) Be certified to comply with a local flood proofing standard
approved by the Federal Insurance Administration.
d. Manufactured homes shall also meet the standards in Subsection
(D).
Exhibif A
Page 10 of 12
B. Standards for utilities.
1. All new and replacement water supply and sanitary sewage systems
shall be designed to minimize or eliminate infiltration of floodwaters into the system and
discharge from systems into floodwaters.
2. On-site waste disposal systems shall be located to avoid impairment to
them or contamination from them during flooding.
C. Standards for subdivisions.
1. All preliminary subdivision proposals shall identify the flood hazard area
and the elevation of the base flood.
2. All final subdivision plans will provide the elevation of proposed
structures and pads. If the site is filled above base flood, the final pad elevation shall be
certified by a registered professional engineer or surveyor and provided to the
floodplain administrator.
3. All subdivision proposals shall be consistent with the need to minimize
flood damage.
4. All subdivision proposals shall have public utilities and facilities, (e.g.,
sewer, gas, electrical and water systems) located and constructed to minimize flood
damage.
5. All subdivisions shall provide adequate drainage provided to reduce
exposure to flood hazards.
D. Standards for manufactured homes. All new and replacement manufactured
homes and additions to manufactured homes shall:
1. Be elevated so that the lowest floor is at or above the base flood
elevation; and
2. Be securely anchored to a permanent foundation system to resist
flotation, collapse or lateral movement.
E. Floodways. Located within the areas of special flood hazard established in
Subsection 21.22.030(B) are areas designated as floodways. Since the floodway is an
extremely hazardous area due to the velocity of floodwaters that carry debris, potential
projectiles, and erosion potential, the following provisions apply:
1. ,
Until a
regulatory floodway is adopted, no new construction, substantial development
f incl~ ill) shall be permitted within Zones Al-30 and AE, unless it is
demonstrated that the cumulative effect of the proposed development, when
combined with all other development, will not increase the water surface
elevation of the base flood more than 1 foot at any point within the City of
Campbell.
2. ,
. Within an adopted regulatory floodway, the City of Campbell shall
prohibit encroachments, including fill, new construction, substantial
improvements, and other development, unless certification by a registered civil
engineer is provided demonstrating that the proposed encroachments shall not
Exhibit A
Page 11 of 12
result in anv increase in flood levels during the occurrence of the base flood
discharge.
3. If subsections 21.22.050(E)(1)gnd 21.22.050(E)(2) are satisfied, all
new construction, substantial improvement, and other proposed new
development shall comply with all other applicable flood hazard reduction
provisions of Section 21.22.050.
21.22.060 Variance procedure. A. Appeal board.
1. The city council shall hear and decide appeals and requests for
deviations from the requirements of this chapter.
2. The city council shall hear and decide appeals when it is alleged that
there is an error in any requirement, decision or determination made by the floodplain
administrator in the enforcement or administration of this chapter.
3. In passing upon applications, the city council shall consider all technical
evaluations, all relevant factors, 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;
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 for the proposed use that are
not subject to flooding or erosion damage;
g. The compatibility of the proposed use with existing and anticipated
development;
h. The relationship of the proposed use to the city's General Plan and
floodplain management program for the subject area;
i. The safety of access to the property in times of flood for ordinary
and emergency vehicles;
j. The expected heights, velocity, duration, rate of rise, and sediment
transport of the floodwaters expected at the site; and
k. The costs of providing governmental services during and after flood
conditions, including maintenance and repair of public utilities and facilities, (e.g.,
sewer, gas, electrical, and water systems, and streets and bridges.)
4. Generally, a deviation may be issued for new construction and
substantial improvements to be erected on a lot of one-half acre or less in size
contiguous to and surrounded by lots with existing structures constructed below the
base flood level, providing items (A)(3)(d) through 21.22.060(A)(3)(k), above, have
been fully considered. As the lot size increases beyond one-half acre, the technical
justification for issuing the variance increases.
Exhibit A
Page 12 of 12
a. Upon consideration of the factors in Subsection 21.22.060(A)(3),
above, and the purposes of this chapter, the city council may attach conditions to the
granting of a deviation as necessary to further the purposes of this chapter.
b. The floodplain administrator shall maintain the records of all appeal
actions and report any deviation to the Federal Insurance Administration upon request.
B. Conditions for deviations.
1. Deviations may be issued for the reconstruction, rehabilitation, or
restoration of structures listed in the National Register of Historic Places or the State
Inventory of Historic Places, without regard to the procedures set forth in the remainder
of this section.
2. Deviations shall not be issued within any designated floodway if any
increase in flood levels during the base flood discharge would result.
3. Deviations shall only be issued upon a determination that the deviation is
the minimum necessary, considering the flood hazard, to afford relief.
4. Deviations shall only be issued upon:
a. A showing of good and sufficient cause;
b. A determination that failure to grant the deviation would result in
exceptional hardship to the applicant; and
c. A determination that the granting of a deviation will not result in
increased flood heights, additional threats to public safety, extraordinary public
expense, create nuisances, cause fraud on or victimization of the public or conflict with
existing local laws or ordinances.
5. Deviations may be issued for new construction and substantial
improvements and for other development necessary for the conduct of a functionally
dependent use, provided that the provisions of subsections (B)(1) through (B)(4),
above, are satisfied and that 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.
6. Any applicant to whom a deviation is granted shall be given written
notice that the structure will be allowed to be built with a lowest floor elevation below
the regulatory flood elevation, and that the cost of flood insurance will be
commensurate with the increased risk resulting from the reduced lowest floor elevation.
A copy of the notice shall be recorded by the floodplain board in the office of the Santa
Clara County recorder and shall be recorded in a manner so that it appears in the chain
of title of the affected parcel of land.
