REPORT TO: Doug Russell, City Manager
FROM: PJ Sorensen, Kalispell Planning Dept
SUBJECT: Ordinance 1724 - Floodplain Ordinance Update and revised FIRM panels —
I" Reading
MEETING DATE: May 20, 2013
BACKGROUND: The City of Kalispell last updated its floodplain ordinance in 2007 at the
same time that new digital floodplain maps were adopted. The maps (referred to as "panels"), each
show a particular area of the county. The City of Kalispell falls to one degree or another on a total of
6 different panels.
Recently, FEMA conducted a study of the Evergreen area and issued several new panels. None of
the changes impact the city directly (see the attached map showing the limits of the changes, which
generally occur east of the Stillwater River in Evergreen). However, FEMA requires us to adopt a
new panel if our jurisdictional area falls on it. If we do not adopt it, we could be suspended from the
national flood insurance program. In this case, panels 1420, 1810, and 1830 for Flathead County
were revised by incorporating the new Evergreen study. Portions of panels 1420 and 1810 include
the city, so we need to adopt the new panels. No portion of the city is on panel 1830, so we do not
neM to adopt that particular one. In April, the County Commissioners adopted the revised panels
with the new study.
When the revised panels are adopted, FEMA also conducts a review of the text of our floodplain
ordinance. There were several minor updates that they are requiring us to adopt as well. The
updates are primarily definitional and better clarify existing federal standards which are reflected in
the ordinance. As a side note, the State of Montana DNRC is working on a new model ordinance
which should be ready later this year that we will need to adopt and will be brought to the council for
its consideration. In the meantime, we still need to make the FEMA-mandated changes.
RECOMMENDATION: City Council approve Ordinance 1724 on first reading.
FISCAL EFFECTS: Approval of the request would have minimal fiscal effect to the city.
Denial of the request would result in the city's removal from the flood program, which would impact
any federally -backed mortgages for homeowners and potential homeowners in the city.
Respectfully submitted,
PJ Sorensen 61

ORDINANCE NO.1724
AN ORDINANCE AMENDING ORDINANCE NO.1611, CODIFIED AS CHAPTER 10A
KALISPELL CITY CODE, ADOPTING REVISED PANEL NUMBERS 1420 AND 1810
IN COMPLIANCE WITH M.C.A. 76-5-101 THROUGH 76-5-406 AND DECLARING AN
EFFECTIVE DATE.
WHEREAS, the flood hazard areas of the City of Kalispell are subject to periodic inundation,
which results in loss of life and property, health and safety hazards, disruption of
commerce and governmental services, and extraordinary public expenditures for
flood protection and relief, all of which adversely affect the public health, safety
and general welfare; and
WHEREAS, 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 flood hazard areas by uses vulnerable to floods and hazardous to
other lands because they are inadequately elevated, flood proofed or otherwise
protected from flood damage; and
WHEREAS, it is the purpose of this ordinance to promote the 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
and generally undertaken at the expense of the general public;
(4) Minimize prolonged business interruptions;
(5) Minimize damage to public facilities and utilities such as water and gas
mains, electric, telephone and sewer lines, 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 in such a manner as to minimize future
flood blight areas; and
(7) Insure that potential buyers are notified that property is in a flood area.;
and
WHEREAS, in order to accomplish its purposes, this ordinance uses the following methods:
(1) Restrict or prohibit uses that are dangerous to health, safety or property in
times of flood, or cause excessive increases in flood heights or velocities;
(2) Require that uses vulnerable to floods, including facilities which serve
such uses, be protected against flood damage at the time of initial
construction;
(3) Control the alteration of natural floodplains, stream channels, and natural
protective barriers, which are involved in the accommodation of
floodwaters;
(4) Control filling, grading, dredging and other development which may
increase flood damage;
(5) Prevent or regulate the construction of flood barriers which will
unnaturally divert flood waters or which may increase flood hazards to
other lands; and
WHEREAS, this Ordinance should be enacted in order to comply with the Montana Floodplain
and Floodway Management Act (Title 76, Chapter 5 MCA) and to ensure
compliance with the requirements for the continued participation by the City of
Kalispell in the National Flood Insurance Program. Land -use regulations which
are hereby adopted are to be applied to all identified 100-year floodplains within
the local jurisdiction; and
WHEREAS, municipalities have authority to adopt ordinances as provided for in Section 7-1-
4123, MCA to promote the general public health and welfare. Other authority for
municipalities and counties to adopt floodplain management regulations appears
in Section 76-5-101 through 406, MCA.
BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF KALISPELL, MONTANA,
AS FOLLOWS:
SECTION I. The City of Kalispell Municipal Code codified at Chapter 10A of
the Code is hereby amended as set forth in Exhibit "A", attached

ORDINANCE. These regulations are in accordance with and exercising the authority of laws of
the State of Montana, Chapter 5, Floodplain and Floodway Management, 76-5-101 through 76-5-
406, Montana Code Annotated 2003, and following the guidmee regulations of the Code of
Federal Regulations administered by the Federal Emergency Management Agency (FEMA).
Article 2 DEFINITIONS
ALTERATION: Any man-made change that changes a floodplain or watercourse, including, but
not limited to, of an addition to a structure that either increases its external dimensions or
increases its potential flood hazard.
FENCE: As used in this ordinance, fences shall include barbed wire, wood rail, and similar
fences that have a low impact to the flow of water and shall not include solid walls or permanent
fences crossing channels.
Historic Structure: Any structure that is : (a) Listed individually in the National Register of
Historic Places or preliminarily determined as meetingtquirements for individual listing on
the National Register; (b) Certified or preliminarily determined as contributing to the historical
significance of a registered historic district; (c) Individually listed on a state inventory of historic
places, or (d) Individually listed on a local inventory of historic places.
1OA-5 Basis for Establishing the Areas of Special Flood Hazard.
The areas of special flood hazard identified by the Federal Emergency Management Agency in
the current scientific and engineering report entitled, "The Flood Insurance Study for Flathead
County, Montana, and Incorporated Areas," dated June 18, 2013 con�os=,,o, 28, 2007, with the
most effective Flood Insurance Rate Maps and/or Flood Boundary-Floodway Maps (FIRM
and/or FBFM) listed below dared September- 28, 2007.Permits are required for all proposed
construction and other development within special flood hazard areas.

10A-6 Rules for Interpretation of Floodplain Boundaries.
The boundaries of the 100-year floodway shall be determined by scaling distances on the Official
Floodplain Maps and using the floodway data table and stream profiles contained in the flood
insurance study report. The maps may be used as a guide for determining the 100-year floodplain
boundary, but the exact location of the floodplain boundary shall be determined where the base
flood elevation intersects the natural ground. For unnumbered A Zone and AO Zone floodplains,
where there is a conflict between a mapped floodplain boundary and actual field conditions, the
Floodplain Administrator may interpret the location of the 100-year floodplain boundary based
on field conditions or available historical flood information. Where the surveyed elevation
provides greater elevation information than the floodplain map and indicates that the
land/structure may be determined to be out of the floodplain, the homeowner/landowner needs to
advise the Floodplain Administrator and may submit a letter of map change (LOMC) to FEMA.
10A-15 Duties and Responsibilities of the Floodplain Administrator.
Duties and responsibilities of the Floodplain Administrator shall include, but not be limited to,
the following:
I. When a regulatory floodwav has been designated, the Floodplain Administrator must
prohibit new construction, substantial improvements, or other development (including
fill) within the regulatory floodway unless it has been demonstrated through hydrologic
and hydraulic analyses performed in accordance with standard engineering practices that
the proposed encroachment would not cause an increase in the base flood elevation.
J. Under the provisions of 44 CFR Chapter 1, Part 65.12, of the National Flood Insurance
Program regulations, a community may approve certain development in Zones Al-30,
AE, All, on the community's FIRM which increases the water surface elevation of the
base flood by more than zero (0.00) feet in a regulatory floodway or one-half foot in a
special flood hazard area with no regulatory floodway, provided that the community first
completes all of the provisions required by Seefien 44 CFR 65.12.
(renumber remainder of 10A-15 accordingly)
10A-26 F000dway Fringe.
B.Uses Requiring Permits: All uses allowed in the floodway subject to the issuance of a
permit according to the provisions of these regulations shall also be allowed by permit
within the designated floodway fringe. In addition, new construction, substantial
improvements, alterations to structures (including, but not limited to, residential,
Z:\wp\ord\1724 amended Floodplain.doc
commercial, agricultural and industrial) and suitable fill shall be allowed subject to the
following conditions:
4. Non -Residential. The new construction, alteration, and substantial improvement
of commercial and industrial buildings must be constructed on suitable fill with a
permanent foundation such that the lowest floor elevation (including basement) is two
(2) or more feet above the BFE (Base Flood Elevation), or the building must be
adequately floodproofed to an elevation no lower than two (2) feet above the elevation
of the one hundred (100) year flood. Certification is required by a registered
professional engineer, architect, or other qualified person that floodproofing methods
are adequate to withstand the flood depths, hydrodynamic and hydrostatic pressures,
velocities, impact, buoyancy, and uplift forces associated with the one hundred (100)
year flood (Article 5).
5. If the building is designed to allow internal flooding of the lowest floor, use of the
lowest floor must be limited to parking, loading areas, and storage of equipment or
materials not appreciably affected by floodwaters. The floors and walls shall be
designed and constructed of materials resistant to flooding to an elevation no lower
than two (2) feet above the BFE. Walls shall be designed to equalize hydrostatic forces
by allowing for entry and exit of floodwaters. Openings may be equipped with screens,
louvers, valves, and other coverings or devices which permit the automatic entry and
exit of floodwaters.
6. Buildings whose lowest floors are used for a purpose other than parking, loading,
or storage of materials resistant to flooding shall be waterproofed to an elevation no
lower than two (2) feet above the BFE. F000dproofing shall include impermeable
membranes or materials for floors and walls and watertight enclosures for all windows,
doors and other openings. These buildings shall be designed to withstand the
hydrostatic pressures and hydrodynamic forces resulting from the base flood.
7. Flood proofing of electrical, heating and plumbing systems shall be accomplished
in accordance with Article 6.
8. See Section 5.4(B)(10) for additional requirements relating to enclosures below
the lowest floor.

RETURN RECEIPT REQUESTED
The Honorable Tammi Fisher
Mayor, City of Kalispell
201 First Avenue East
Kalispell, Montana 59901
Dear Mayor Fisher:
I am writing this letter as an official reminder that the City of Kalispell, Montana, has until
June 18, 2013, to adopt and have the Department of Homeland Security's Federal Emergency
Management Agency (FEMA) Regional Office approve floodplain management measures that
satisfy 44 Code of Federal Regulations (CFR) Section 60.3(d) of the National Flood Insurance
Program (NFIP) regulations.
The City of Kalispell must adopt floodplain management measures, such as a floodplain
management ordinance, that meet or exceed the minimum NFIP requirements (copy enclosed) by
June 18, 2013, to avoid suspension from the NFIP. If suspended, your community becomes
ineligible for flood insurance through the NFIP, new insurance policies cannot be sold, and existing
policies cannot be renewed.
Under the Flood Disaster Protection Act of 1973, as amended, flood insurance must be purchased by
property owners seeking any Federal financial assistance for construction or acquisition of buildings
in Special Flood Hazard Areas (SFHAs). This financial assistance includes certain federally
guaranteed mortgages and direct loans, federal disaster relief loans and grants, as well as other
similarly described assistance from FEMA and other agencies.
In addition, all loans individuals obtain from Federally regulated, supervised, or insured lending
institutions that are secured by improved real estate located in SFHAs are also contingent upon the
borrower obtaining flood insurance coverage on the building. However, purchasing and maintaining
flood insurance coverage on a voluntary basis is frequently recommended for properties located
outside SFHAs.
Your NFIP State Coordinator and FEMA would like to assist the City of Kalispell to ensure it
remains in good standing with the NFIP and avoids suspension from the Program. If your
community is suspended, it may regain its eligibility in the NFIP by enacting the floodplain
management measures established in 44 CFR Section 60.3 of the NFIP regulations. As stated in my
previous correspondence, I recommend you contact your NFIP State Coordinator or the FEMA
Regional Office if the City of Kalispell is encountering difficulties in enacting its measures.
www.fema.gov
The Honorable Tainmi Fisher
MAY Q 3 2013
Page 2
I recognize that your community may be in the final adoption process or may have recently adopted
the appropriate floodplain management measures. Please submit these measures to the Floodplain
Management Program at the Montana Floodplain Management Program. Traci Sears, CFM, the
NFIP State Coordinator, is accessible by telephone at (406) 444-6654, in writing at
1424 Ninth Avenue, Helena, Montana 59620-1601, or by electronic mail at tsears@mt.gov.
The FEMA Regional staff in Denver, Colorado, is also available to assist you with your floodplain
management measures. The FEMA Regional Office may be contacted by telephone at
(303) 235-4800 or in writing. Please send your written inquiries to the Director, Federal Insurance
and Mitigation Division, FEMA Region VIII, at the Denver Federal Center, Building 710,
Box 25267, Denver, Colorado 80225.
In the event your community does not adopt and/or submit the necessary floodplain management
measures that meet or exceed the minimum NFIP requirements, I must take the necessary steps to
suspend your community from the NFIP. This letter is FEMA's final notification before your
community is suspended from the Program.
Sincerely,
David H. Stearrett, CFM, Chief
Floodplain Management Branch
