TO: Honorable City Council
FROM: Yugal K. Lail, City Engineer/Public Works Director
DATE: November 5, 2009 (CC Meeting of 11-18-09)
SUBJECT: Consider Funding for Filing Flood Map Amendments with Federal
Emergency Management Agency (FEMA) for the 2010 Digital Flood
Insurance Rate Map (DFIRM) and a Resolution Amending the Fiscal
Year 2009/10 Budget to Appropriate $100,000 from the General Fund
Reserve to Fund the Proposed 2010 DFIRM Amendments and
Amendments to Chapter 15.24, Floodplain Management of the
Moorpark Municipal Code to Comply with DFIRM 2010
SUMMARY
The City Council is being asked to consider authorizing staff to process Map
Amendments with FEMA to remove a number of residential/commercial/industrial
structures from the 2010 DFIRM 100-year floodplain; and to consider a resolution
amending the Fiscal Year 2009/2010 Budget to increase the General Fund (1000) in an
aggregate amount of$100,000.00 to fund the DFIRM amendments.
BACKGROUND
(A) National Flood Insurance Act of 1968
In 1968, the United States Congress passed the National Flood Insurance Act, which
created the National Flood Insurance Program (NFIP). The NFIP was designed to reduce
future flood losses through local floodplain management and to provide protection for
property owners against potential losses through an insurance mechanism that allows a
premium to be paid for protection of those in need. As part of the agreement for making
flood insurance available to a community, the NFIP requires the community to adopt
floodplain management ordinances that meet certain minimum requirements intended to
reduce future flood losses. The City is responsible for floodplain management within the
City and to provide floodplain information to the property owners. On March 20, 2002 the
City Council adopted Ordinance 279 (Attachment 1) for Floodplain Management and

Flood Damage Prevention and appointed the City Engineer as the Floodplain
Administrator.
(B) Existing FIRM - September 1986
In September 12, 1986, FEMA approved Flood Insurance Rate Map (FIRM) for the City,
this is the current FIRM and will be replaced with new DFIRM on January 20, 2010. In
the FIRM of 1986 the 100-year flood was approximately 16,000 cfs through the Arroyo
Simi with less than 50 structures in the 100-year floodplain requiring flood insurance and
more than 90% of the City was within the 100 to 500 year flood zone, (Zone B and C)
where no flood insurance was required. Less than 10% of the City was in Zone A,
categorized by FEMA as a risk area and requiring flood insurance. Based on information
provided by FEMA, there are approximately 75 structures currently that have flood
insurance, however, some of these structures are not required to have flood insurance.
(C) Prelude to New DFIRM January 2010
After Hurricane Katrina in 2003, FEMA decided to update the DFIRM throughout the
country and in September 2005, FEMA issued the preliminary DFIRM for the City as part
of the update for the County of Ventura. The preliminary DFIRM depicted a large
increase in the 100-year floodplain and floodway for the City as compared to the
September 1986 FIRM, and it is estimated as much as 30% of the City was in the
floodplain or floodway. The main reason for the increase in the floodplain and floodway
was the increase in runoff in the 100-year flood from 1986 to 2003. The 1986 hydrology
for the 100-year storm was approximately 16,000 cfs as compared to 22,000 cfs from the
2003 100-year storm hydrology study. In the development of the preliminary DFIRM map
FEMA hired consultant Nolte and Associates (Nolte) to perform the technical and
scientific studies and they used the latest hydrology and topographic information
available. The hydrology that was used was prepared in 2003 by the Ventura County
Watershed Protection District (VCWPD) in conjunction with the United States Army Corp
of Engineers. The VCWPD 2003 Hydrology showed an increase of approximately 6,000
cubic feet per second (cfs) in the 100-year flood flowing through the Arroyo Simi as
compared to the 1986 FIRM. The Arroyo Simi serves as the main conveyance channel
for storm water through the City and it has two bottlenecks (the railroad bridge crossing to
the south of Princeton Avenue and the Spring Road Bridge) that restrict the channel
capacity to approximately 16,000 cfs. These bottlenecks create breakout in the
stormwater over-spilling the channel and expanding the floodway and floodplain.
(D) September 2005 Preliminary DFIRM
In the September, 2005 preliminary DFIRM, there were:
1. Approximately 1600 new structures in the 100-year floodplain as compared to less
than 50 structures in the 1986 map.
2. The depth of flooding from the 100-year flood was as high as 7 feet. There were
approximately 200 structures in the flood zone with depth of flooding greater than 3
feet.
3. The floodway (the floodway is the channel of stream plus any adjacent floodplain

areas that must be kept free of encroachment so that the 1% annual chance flood
can be carried without substantial increases in flood heights) extended as far north
to Los Angeles Avenue, and included Villa Campesina community, Village
Crest/Water Stone Apartments and all properties between Los Angeles Avenue
and the Arroyo Simi from east of Park Lane to west of Leta Yancy Road.
In the 1986 FIRM the floodway was not defined, however, the flood hazard areas were
confined within the limits of the Arroyo Simi and the floodplain was very minimal with less
than 50 structures in the 100-year floodplain.
On November 9, 2005, a public meeting was held at the City Council Chambers, (all
property owners were advised of this meeting) wherein the preliminary September 2005
DFIRM was discussed along with flood insurance requirements. Representatives from
both FEMA and VCWPD were present. In January 2006, the City Council authorized
staff to appeal the preliminary 2005 DFIRM based on technical and scientific data. The
appeal process through FEMA is very stringent and can only be based on sound
technical and scientific data, as previously stated. The hydrology that was used by FEMA
consultant, Nolte was prepared in 2003 by the Ventura County Watershed Protection
District (VCWPD) in conjunction with the United States Army Corps of Engineers.
The City appeal was based on the technical and scientific principle that a percentage of
the storm water breakouts at the two bottlenecks can be treated as disconnected from the
main steam Arroyo Simi, resulting in storm water flowing through the City streets. City
streets are designed as conveyance of storm water for 10-year frequency storm. This
rationale was previously used by FEMA for the City of Simi Valley, wherein the limits of
the floodway and floodplain boundaries were reduced. The topography used in the
preparation of the 2005 preliminary DFIRM was developed by VCWPD in 2001 and
provided to FEMA as the best available. In the appeal process the topography used was
based on latest data provided by VCWPD. Unfortunately it could have been updated but
new topography can cost as much as $100,000.00. The topography used did not include
the new data from Moonsong/Flory and Gisler/Fiji area.
The City developed a Scope of Work and selected Tetra Tech Inc. as the consultant to
perform the appeal based on their qualifications and technical experience. General
Funds in the amount of $41,000 were used in FY 2005/2006 for the preliminary DFIRM
appeal. Pacific Communities and Shea Homes developers on the north of the Arroyo
contributed approximately $85,000.00 towards the City's DFIRM appeal in FY 2006/2007
and FY 2007/2008. Both Pacific Communities and Shea Homes in the development
stages of their properties were aware of City's appeal and contributed funds in this effort
since the preliminary DFIRM had adversely affected their project that was contiguous with
the Arroyo.
(E) Appeal Process and Outcome
During the period of February 2006 through August 2007, the City's consultant, Tetra

Tech Inc., submitted technical and scientific data to FEMA to support the appeal and as
requested by FEMA. On January 9, 2008, FEMA accepted the City's appeal as
warranted. The appeal resulted in the following changes to the preliminary DFIRM of
September 2005:
1) Reduction of the floodway to within the limits of the Arroyo, with a maximum width
of approximately 500 feet.
2) Removal of many residential/commercial structures from the floodway on the north
side of the Arroyo Simi including the Villa Campesina community, Vintage Crest
Apartments, Water stone Apartments and all structures south of Los Angeles
Avenue west of Leta Yancy and east of Park Lane.
3) Removal of approximately 520 residential/commercial structures from to the 100-
year floodplain south of Poindexter, from Gabbert Road to Moorpark Avenue; on
High Street and downtown areas from Moorpark Avenue to Spring Road; and
properties to the rear of Vons.
4) The depth from the 100-year flood was reduced to a maximum of 3 feet for
approximately 200 structures that were greater than 3-foot zone. These structures
are located in the downtown area and areas south of Poindexter Avenue, from
Gabbert Road to Moorpark Avenue.
5) Addition of approximately 170 homes to the 100-year floodplain on the north of the
Arroyo Simi in the Butter Creek/Peppermill, Harvester, and small portion of
Maureen Lane areas.
At the same time, FEMA requested for levee certification for the Arroyo Simi, as a new
requirement for the approval of the DFIRM, and this delayed the approval of the DFIRM.
All the levees within the City, with the exception of one located on the south of the Villa
Del Arroyo Mobile Home Park, is owned and maintained by the VCWPD. VCWPD,
working in conjunction with FEMA, determined that all their levees within the City could
not be certified as the levee did not have the required 3 foot of freeboard. The levee
owned and maintained by the Villa Del Arroyo Mobile Home Park was not certifiable, as it
is not owned and maintained by a governmental agency, a FEMA requirement for
certification.
In November 2008, FEMA determined that the levee owned by Villa Del Arroyo was not
acceptable for certification and approximately 240 structures in Villa Del Arroyo Mobile
Home Park were added to the revised preliminary DFIRM 100-year floodplain.
On December 22, 2008, FEMA published a notice in the Star advising of the statutory 90-
day period provided for appeals. At this juncture a second appeal was not filed with
FEMA as staff determined that there was no new technical and scientific information/data
to support further appeals. The new preliminary DFIRM was published on the City's web
site with an explanation of the appeal.
On July 20, 2009, the City was advised of the approved FEMA map and on October 7,
2009, the City received the official DFIRM map. On the receipt of the approved DFIRM

notices were mailed to all affected property owners to advise them of flood insurance
requirements. On November 2, 2009, a public a meeting was held to address concerns
regarding the City appeal, flood insurance requirements, and grandfathering
requirements. Representatives from FEMA and VCWPD were present to respond to
concerns and questions on the new DFIRM.
(F) VCWPD Activities in Moorpark, Past, Present and Future
The Arroyo Simi within the City, along with the tributaries of Strathern Drain, Happy Camp
Drain, Walnut Canyon Drain, Peach Hill Drain, and Gabbert Drain, are under the
jurisdiction of VCWPD. Since 1986, other than routine maintenance, little or no capital
improvements have occurred to the Arroyo Simi and its tributaries with the exception of
Happy Camp Drain. The storm of January 2005 flooded the Happy Camp area and
caused some damage. VCWPD obtained a federal grant and performed improvements
to the Happy Camp Drain upstream of the City limits in 2008.
On an annual basis, City staff has reviewed the Capital Improvement Program (CIP) for
the VCWPD. Improvements to the Arroyo Simi from the railroad crossing to Tierra
Rejada Bridge have been included in the VCWPD's annual CIP until 2006. After 2006
these projects were placed in the future VCWPD's 5-10 years CIP due to insufficient
funding.
The VCWPD is moving towards environmentally friendly projects using less concrete
lined channels and more unlined channels, requiring open space and additional rights of
way. VCWPD is currently working with stakeholders within the Calleguas Watershed
(Arroyo Simi is included in this watershed) area to develop a global integrated water
management plan. This plan is estimated to cost over $44 million and would include
detention basins that would potentially resolve all flooding issues within the City. This
plan is in its infancy and is under review by staff.
At the present time VCWPD has no plans for the next 5-10 years for improvements to
their storm drain facilities within the City that can remove structures from the 2010
DFIRM.
(G) City of Moorpark Storm Drain Improvements
The City recently completed the improvements to approximately 900 linear feet of the
Walnut Canyon Storm Drain. The existing storm drain was undersized and could not
carry the 100-year storm; the new storm drain was upsized and designed to carry the
100-year storm with acceptable freeboard. The City through the use of developer funds
completed improvements for the widening of the Los Angeles Avenue bridge structure,
and the reconstruction of the Spring Road Bridge. The Spring Road bridge was designed
based on the pre-2003 hydrology of approximately 16,000 cfs.
(H) Developer Funded Improvements
The William Lyons development (Tract 5147/Meridian Hills), as part of their development

agreement, constructed a regional detention basin upstream of the Walnut Canyon Drain.
This regional detention basin will potentially remove all structures from the 100-year
floodplain that is attributable to the Walnut Canyon Drain. A Letter of Map Revision
(LOMB) can be filed for the estimated 60 structures to be removed from the 100-year
flood. Toll Brothers Tract 4128 and Pardee Tract 5045 constructed project specific
detention basins that serve their local needs. Vintage Crest Apartments and Water Stone
Apartments dedicated right-of-way to VCWPD and constructed detention basins to serve
their projects.
DISCUSSION
The new DFIRM will be effective January 20, 2010. There are approximately 1,200 new
structures in the new 100-year floodplain DFIRM map as compared to the 1986 map
where there were approximately 50 structures. The property owners in the new 100-year
floodplain have until January 20, 2010, to purchase flood insurance at the pre-January
20, 2010, flood insurance rate. Flood insurance is required by all federally guaranteed
mortgages for a maximum amount of $250,000. All the affected property owners have
been notified and a public meeting was held on November 2, 2009, to answers all
questions pertaining to the DFIRM, floodplain and flood insurance requirements.
With the new FEMA 2010 DFIRM there are approximately:
• 500 structures in Zone AO (1 foot); approximately 400 residential of which 200 are
the Butter Creek/Peppermill/Harvester area/Maureen Lane, 75 in the Moorpark
Estates, 125 in the downtown area and 100 commercial/industrial in the
Gabbert/Poindexter area.
250 structures in Zone AO (2 foot); approximately 200 residential in the
Shasta/Sierra and Flory/Sherman Areas and 50 commercial/industrial in the
Gabbert/Poindexter area.
• 60 structures in Zone AO (3 foot); approximately 20 residential at Millard/Sherman
area and 40 commercial/industrial in the Science Drive and Commerce Avenue
areas.
130 structures in Zone AE on the north side of the Arroyo between Moorpark
Avenue and Spring Road.
240 structures in Zone A (Villa Del Arroyo) due to the uncertified levee.
At the November 2, 2009, public meeting, staff informed the property owners that a
recommendation would be made to the City Council to fund the processing of Letter of
Map Amendment (LOMA Attachment 3) to FEMA for structures in Zone AO (1 foot) for
potential removal from the 100-year floodplain. From a cursory review of record drawings
and existing field conditions, it is staff's opinion that many structures within the 100-year

floodplain for the Butter Creek/Peppermill, Moonsong/Flory and Gisler/Fiji areas may be
removed from 100-year floodplain, however, this may not hold true for structures within
the Shasta/Sierra and downtown areas due to the relatively flat topography.
With the completion of the Meridian Hills detention basin, and the larger Walnut Canyon
Storm Drain, the 2010 DFIRM 100-year floodplain can be further reduced. A Letter of
Map Revision (LOMR) can be submitted to FEMA to revise the 2010 DFIRM based on
these completed improvements. Most or all of the 60 properties within the 100-year
floodplain attributed to Walnut Canyon tributary area may be removed.
The developers for Tract 5133 & 5425, (Shea Homes) and Pacific Communities on the
south side of Los Angeles Avenue, will have to file for Letter of Map Revision Fill
(LOMRF) to remove their proposed structures from within the 100-year 2010 DFIRM.
Commonwealth Studios and Hitch Ranch, as part of their development requirements, will
be conditioned to construct a regional detention basin on the Hitch Ranch property. This
regional detention/retention basin will remove all the remaining structures within the 100-
year floodplain from the Gabbert/Walnut Canyon drainage areas.
INSURANCE RATES
For all new structures in the 100-year floodplain 2010 DFIRM, property owners can
purchase insurance at the pre-FIRM rate (Attachment 4). The maximum policy of
$250,000 can cost $348.00/year. If purchased after January 20, 2010, these policies can
cost as much as $2,000.00.
NEW FLOOD ORDINANCE
With the implementation of the 2010 DFIRM the existing City Ordinance No. 279 for
floodplain management and flood damage prevention would be obsolete. Chapter 15.24
Floodplain Management would have to be updated to comply with the 2010 DFIRM.
PROPOSED ACTIONS
1. Staff proposes to authorize City's GIS consultant to prepare overlays of 2010
DFIRM on city map and on City's GIS system.
2. Consultant will review all structures designated Zone AO 1 foot, (approximately
500 structures) and if Letter of Map Amendment (LOMA) criteria are met, a LOMA
will be processed.
3. Consultant will perform LOMR for the Walnut Canyon Detention Basin and storm
drain to remove approximately 60 properties from the 2010 DFIRM.
4. Consultant will perform LOMRF for the Moorpark Police Services building, the
Ruben Castro Human Health Services proposed building, and the Moorpark Public
Services Facility building.

Section 15.24.020 Findings of fact.
A. The flood .hazard. areas of City of Moorpark are subject
to periodic inundation which results in loss of life and
property, health and safety hazards, disruption of commerce and j
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.
B. These flood losses are caused by uses that are
inadequately elevated, floodproofed, or protected from flood
damage. The cumulative effect of obstructions in areas of
special flood hazards which increase flood heights and
velocities also contribute to the flood loss.

power which control development in flood-prone areas. This term
describes federal, state or local regulations in any combination
thereof, which provide standards for preventing and reducing,
flood loss; and damage.
"Floodproofing" means any combination of structural and
nonstructural additions, - changes, or adjustments to structures
which reduce or eliminate flood damage to real estate or
improved . real property, water and sanitary facilities.,

public. In examining this requirement, the City Council will
consider the fact that every newly constructed building adds to
government responsibilities and remains a part., of the community
for fifty years to one hundred years. Buildings that are
permitted to be constructed below the base flood elevation are
subject during all those years to increased .risk of damage from
floods, while future owners of the property and the community as
a whole are subject to all the costs, inconvenience, danger, and
suffering that those increased flood damages bring. In addition,

personal preferences, or the disapproval of one's neighbors
likewise cannot, as a rule, qualify as an exceptional hardship.
All of these problems can be resolved through` other means
without granting. a variance, even if the alternative is more

1. Outside of a manufactured home park or subdivision,
2. In a new manufactured home park or subdivision,
3. In an expansion to an existing manufactured home park or
subdivision,
4. In an existing manufactured home park or subdivision on a
site upon which a manufactured home has incurred "substantial
damage" as the result of a flood, shall be elevated on a
permanent foundation such that the lowest floor of the
manufactured home `is elevated two feet above the base flood
elevation and be securely fastened to an adequately anchored
foundation system to resist flotation, collapse and lateral
movement.
S. All manufactured homes to be placed` or substantially
improved on sites in an existing manufactured home park or
subdivision within Zones Al-30, AH and AE on the community's
Flood Insurance Rate` Map that are not subject to the provisions
of paragraph 15.24.190.A will be securely fastened to an
adequately anchored foundation system to resist flotation,
collapse, and lateral movement, and be elevated so that either
the:
1. Lowest floor of the manufactured home is at two feet
above the base flood elevation, or
2. Manufactured home chassis is supported by reinforced
piers or other foundation elements of at least equivalent
strength that are no less than 36 inches in height above grade

the lowest floor including basement shall be certified by a
o00028
Ordinance No. 279
Floodplain Management

registered professional engineer or surveyor, and verified by
the community building inspector to be properly e-levated. Such
certification and verification shall be provided to the
Floodplain Administrator.
Section 15.24.200 Standards for recreational vehicles. .
A. All recreational vehicles placed on sites within Zones
Al-30, AH, and: AE on the community's Flood Insurance Rate Map
will either:
1. Be on the site for fewer than 180 consecutive days, and
be fully licensed and ready for highway use - -a recreational
vehicle is ready for highway use if it is on its- wheels or
jacking system, is attached to the site only by quick disconnect
type utilities and security devices, and has no permanently
attached additions, or
2. Meet the permit. requirements of Section 15.24.130 through
15.24.150 of this ordinance and the elevation and anchoring
requirements for manufactured homes in Section 15.24.190.A.
Section 15.24.210 Floodways.
Located within areas of special flood hazard established in
Section, are areas designated as floodways. Since the
floodway is an extremely hazardous area due to the velocity of
floodwaters, which carry debris, potential projectiles, and
erosion, potential, the following provisions apply;
A. Prohibit encroachments, including fill, new
construction, substantial improvement, and other new development
unless certification by a registered professional -- engineer is
provided demonstrating that encroachments shall not result in
any increase_ in [the base] flood elevation during the occurrence
of the base_flood discharge.
B. If Section 15,.24.220.A is satisfied,, all new
construction,,,_ substantial improvement, and other proposed new j
development shall 'comply with all other applicable flood hazard
reduction provisions of Section 15.24.170 through 15.24.220.
Article VI. Variances
Section 15.24.220 Nature of variances.
The variance criteria set forth in this section of the
ordinance 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 granted for a parcel of property with
physical characteristics so unusual that. complying with the
requirements of this ordinance would create an exceptional
000029
Ordinance No. 279
Floodplain Management
Page 21
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.
It is the :duty of the City to help protect its citizens
from flooding. This need is so compelling and the implications
of the cost of insuring-a structure built below 'flood level are
so serious that variances from the flood elevation or from other
requirements in the flood ordinance are quite rare. The long-
term goal of preventing and reducing flood loss and damage can
only be met if variances are strictly limited. Therefore, the
variance guidelines provided in this ordinance are more detailed
and contain multiple provisions that must be met before a
variance I can be properly granted. The criteria are designed to
screen out those situations in which alternatives other than a
variance are more appropriate.
Section 15.24.230 Variance process.
A. Variances shall be processed in accordance with Chapter
17.44 "Entitlement-Process and Procedures" of the Municipal
Code. The substance of all variances shall be in compliance with
all FEMA requirements
.1. Filing shall be in accordance with Section 17.44.040 of
the Municipal Code.
2. Noticing and Hearing shall be in accordance with Section
17.44.050 of the Municipal Code. -
3. Entitlements shall be in accordance with Section
17.44.030 of the Municipal Code.
B. In determining approval or denial of requests for
variances, the City Council shall consider all technical'
evaluations, all relevant factors, standards specified in other
sections of this ordinance, and each of the following:
1. Danger that materials may be swept onto. other lands to
the injury of others.
2. Danger of life: and property due to flooding or erosion
damage,
3 Susceptibility of the proposed facility and its contents
to flood damage and the effect of such damage on the existing
individual owner and future owners of the.property.
4. Importance of the services provided by the proposed
facility to: the community.
5. Necessity to the facility of a waterfront location, where
applicable.
000030
Ordinance No. 279
Floodplain Management
Page 22
6. .Availability of alternative locations for the proposed
use that are not subject to flooding or erosion damage.
7. Compatibility. of the proposed use with existing and
anticipated development.
8. Relationship of the proposed use to the comprehensive
plan and floodplain management program for that area.
9. Safety, of access to the property in time of flood for
ordinary and emergency vehicles.
10,. Expected, heights, velocity, duration, rate of rise,
and sediment transport. of the floodwaters expected at the site.
11. Costs o.f providing governmental services during and
after flood .conditions, including, maintenance and repair of
public utilities and facilities such as sewer, gas,, electrical,
and water system, and streets and bridges
C. Any applicant to whom a variance is granted,:..shall be
given written notice over the signature of - the _Floodplain
Administrator that:
1. The issuance of a variance to construct a structure below
the base flood level will result in increased premium rates for
flood insurance in accordance with Federal law;
2. Such construction below the base flood level increases
risks to life and property; and
3. A copy of the notice shall be, .recorded by the Floodplain
Administrator in the Office of the Ventura County. Recorder, and
shall be recorded in a manner so that it appears in the chain of j
title of the affected parcel of land. A copy of the recorded
notice shall be: submitted to the Federal Insurance
Administration, Federal Emergency Management Agency.
D. The Floodplain Administrator will maintain a record of
all variance actions, including justification for their
issuance, and report such variances issued in its biennial
report submitted to: the Federal Insurance Administration,
Federal Emergency Management Agency.
Section 15.24.240 Conditions for variances.
A. Generally, variances may be issued for new construction,
substantial improvement and other proposed new development 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 that the procedures of
Sections 15.24. 120 through 15.24.210 of this ordinance have. been:
fully considered. As the lot size increases beyond one-half
acre, the technical justification required for issuing the
variance increases.
00003-1
Ordinance No. 279
Floodplain Management
Page 23
B. Variances may be issued for the repair or rehabilitation
of "historic structures" as defined in Section 15.24.050 of this
ordinance upon a determination that the proposed repair or
rehabilitation will not preclude the structure's continued
designation as an historic structure and the variance is the
minimum necessary to preserve the historic character and design
of the structure.
C. Variances shall not be issued within any mapped
regulatory floodway if any increase .in flood levels during the
base flood discharge would result.
D.- Variances shall only be issued upon a determination that
the variance is the "minimum necessary" considering the flood
hazard, to afford relief. "Minimum necessary" means to afford
relief with a minimum of deviation from the requirements of this
ordinance. For example, in the case of variances to an elevation
requirement, this means the City Council need not grant
permission for the applicant to build at grade, or even to
whatever elevation the applicant proposes, but, only to that
elevation which the City Council believes will both provide
relief and preserve the integrity of the local ordinance.
E. Variances shall only be issued upon a:
1. Showing of good and sufficient cause;
2. Determination that failure to grant the variance would
result in exceptional "hardship" (as defined in Section
15.24.050 of this ordinance) to the applicant; and
3. Determination that the granting of a variance will not
result in increased flood heights, additional threats to public
safety, - or extraordinary public expense, create a nuisance (as
defined in Section 15.24.050 = see "Public safety or nuisance") ,
cause fraud or victimization (as defined in Section -15.24.050)
of the public, or conflict with existing local laws or
ordinances.
F. Variances may be issued for new construction,
substantial improvement, and other proposed new development
necessary for the conduct of . a functionally dependent use
provided that the provisions of Sections 15.24.240.A through
15,24.240.E are satisfied and that the structure or other
development is protected' by methods that minimize flood damages
during the base flood and does not result in additional threats
to public safety and does not create a public nuisance.
G. Upon consideration of the factors of Sections 15.24.220
and 15.24.230 and the purposes of. this chapter, the City Council
may attach such conditions to the granting of variances as it
deems necessary to further the purposes of this ordinance.

Special Flood Hazard Areas Subject to Inundation by the 1%Annual
Chance Flood
The 1%annual flood (100-year flood), also known as the base flood, is the flood that has a 1%chance of
being equaled or exceeded in any given year. The Special Flood Hazard Area is the area subject to
flooding by the 1%annual chance flood. Areas of Special Flood Hazard Included Zones A, AE,AH,AO,
AR,AN,V and VE. The Base Flood Elevation is the water-surface elevation of the I%annual chance
flood.
Zone A No Rase Flood Elevations determined.
Zone AE Base Flood Elevations determined.
Zone AH Flood depths of 1 to 3 feet(usually areas of ponding); Base Flood Elevations
determined.
Zone AO Food depths of 1 to 3 feet(usually sheet flow on sloping terrain); average depths
determined. For areas of alluvial fan flooding, velocities also determined.
Special Flood Hazard Area formerly protected from the 1%annual chance flood by
Zone AR a flood control system that was subsequently decertified. Zone AR indicates that
the former flood control system is being restored to provide protection from the 11%
annual chance or greater flood.
Zone AN Area to be protected from 1%annual chance flood by a Federal flood protection
system under construction; no Base Flood Elevations determined.
Zone V Coastal flood zone with velocity hazard (wave action); no Base Flood Elevations
determined.
Zone VE coastal flood zone with velocity hazard(wave action); Base Flood Elevations
determined.
imFloodway Areas in zone AE
The floodway is the channel of stream plus any adjacent floodplain areas that must be kept free of
encroachment so that the 11%annual chance flood can be carried without substantial increases in flood
heights,
Other Flood Areas
Areas of 0.2%annual chance flood; areas of 1%annual chance flood with average
Zone X depths of less than 1 foot or with drainage areas less than 1 square mile; and
areas protected by levees form 1%annual chance flood.

Overview of Maps and Map Change Processes for Properties
As part of its administration of the National Flood Insurance Program(NFIP),the Federal Emergency
Management Agency(FEMA)publishes flood hazard maps,called Flood Insurance Rate Maps,or
FIRMs. The purpose of a FIRM is to show the areas in a community that are subject to flooding and j
the risk associated with these flood hazards. One of the areas shown on the FIRM is a Special Flood
Hazard Area(SFHA). The SFHA is the area that has a 1-percent or greater chance of flooding in any
given year;this area is also referred to by some as the 1-percent-annual-chance floodplain,base
floodplain, or the 100-year floodplain. The flood hazard and risk information presented on the FIRMS
is the result of engineering studies that are performed by engineering companies,other Federal
agencies,or communities,which are reviewed for compliance with FEMA guidelines and approved
by FEMA.
FEMA uses the most accurate flood hazard information available and applies rigorous standards in
developing the FIRMs. However,because of limitations of scale or topographic definition of the
source maps used to prepare a FIRM,small areas may be inadvertently shown within an SFHA on a
FIRM even though the property(legally defined parcel(s)of land,structure[s]).is on natural ground
and is at or above the elevation of the 1-percent-annual-chance flood. This elevation is most
commonly referred to as the Base Flood Elevation,or BFE. Such cases are referred to as "inadvertent
inclusions."
For other small areas,earthen fill may have been placed during construction,thereby elevating a
small area within the SFHA to an elevation that is at or above the BFE.This construction may have
taken place during the time the engineering study was being performed or subsequent to that study.
Because of the limited extent of the elevated area and the limitations of the map scale,it may not
have been possible for FEMA to show this area as being outside the SFHA and so these areas have
been incorrectly included in the SFHA on the FIRM.
Recognizing that these situations do occur,FEMA established administrative procedures to change
the designation for these properties on the FIRM. These processes are referred to as the Letter of Map
000040
h"://www.fema.gov/plan/prevent/flml/finc—loma.shtm nc loma.shtm 10/30/2009

Amendment,or LOMA,process and the Letter of Map Revision Based on Fill,or LOMR-F,process.
Through these processes, an individual who owns,rents,or leases property may submit certain
mapping and survey information to FEMA and request that FEMA issue a document that officially
removes a property and/or structure from the SFHA. In most cases,the applicant will need to hire a
Licensed Land Surveyor or Registered Professional Engineer to prepare an Elevation Certificate for
the property.Upon receiving a complete application forms package,FEMA will normally complete
its review and issue its determination in 4 to 6 weeks.
NFIP Regulations
The regulatory requirements for the LOMA process are documented in Part 70 of the NFIP
regulations. The regulatory requirements for the LOMB F process are documented in Part 65 of the
NFIP regulations. Individuals who are interested in reviewing these regulations may view or
download them from the Guidance Documents and Other Published Resources page of the FEMA
Website.
Guidance Documents
FEMA has prepared guidance documents to assist citizens with their LOMA and LOMR-F
applications and submittals:
• The MT-EZ Form is to be used for LOMA requests involving_a single residential lot or
structure.
• The MT-1 Forms package is to be used for LOMA requests involving multiple residential lots
or structures and for all LOMB-F requests.
Links to these guidance documents are provided in the "Fast Facts" section on the upper right-hand
side of this page.The forms provide step-by-step instructions for requesters to follow and are
comprehensive,ensuring that the requesters'submittals are complete and logically structured.Use of
these forms allows FEMA to complete its review quicker and at lower cost to the NFIP. While
completing the forms may seem burdensome,the advantages to the requesters outweigh any
inconvenience.
LOMA Determination Requirements
• LOMA Requests Involving One or More Structures: For a LOMA to be issued by FEMA to
remove one or more structures from the SFHA,the NFIP regulations require that the lowest
adjacent grade(the lowest ground touching the structure)be at or above the BFE.
• LOMA Requests Involving One or More Lots: For a LOMA to be issued by FEMA to
remove one or more entire lots from the SFHA,the NFIP regulations require that the lowest
point on the lot(s)must be at or above the BFE.
(.oo041
h4://www.fema.gov/plan/prevent/flun/fmc—loma.shtm 10/30/2009
- Page 3 of 10
• Review and Processing Fee: There is no review and processing fee for the FEMA review of a
LOMA request.
• Required Information: The requester is responsible for providing all of the information
needed for FEMA's review of the request,including elevation-information certified by a
Licensed Land Surveyor or Registered Professional Engineer.For a complete listing of the
information that must be submitted in support of a LOMA request,please refer to the MT-EZ
(for single lot/structure requests)or MT-1 application forms package.
LOMB-F Determination Requirements
• LOMR-F Requests Involving One or More Structures For a LOMR-F to be issued by
FEMA to remove the structure from the SFHA,the NFIP regulations require that the lowest
adjacent grade of the structure be at or above the BFE.The participating community must also
determine that the land and any existing or proposed structures to be removed from the SFHA
are "reasonably safe from flooding."
• LOMR-F Requests Involving One or More Lots: For a LOMR-F to be issued by FEMA to
remove the entire lot and structure,both the lowest point on the lot and the lowest floor of the
structure must be at or above the 1-percent-annual-chance flood elevation.
• Review and Processing Fee: FEMA charges a fee for the review and processing of LOMR-F
requests.A link to the current fee schedule is provided in the"Fast Facts"section on the upper
right-hand side of this page.
• Required Information: As with LOMA requests,the requester is responsible for providing all
supporting information,including elevation information certified by a Licensed Land Surveyor
or Registered Professional Engineer. For a complete listing of the information that must be
submitted in support of a LOMR-F request,please refer to the MT-1 application forms
package.
Using eLOMA to Expedite Simple LOMA Requests
To make submitting LOMA requests quicker and easier, FEMA created eLOMA—a web-based
application within FEMA's Mapping Information Platform(MIP). eLOMA provides licensed land
surveyors and professional engineers(Licensed Professionals)a system to submit simple LOMA
requests to FEMA.
Note that not all LOMA requests qualify to be submitted using the eLOMA tool. At this time, only
existing single residential structures or entire legally recorded properties qualify.
If all the required supporting data are submitted according to eLOMA criteria,a Licensed
Professional could obtain a LOMA determination in a matter of minutes. The eLOMA process is
much faster than the standard LOMA process,which historically took up to 60 days.

To ensure the accuracy of the eLOMA determinations,FEMA performs random audits of eLOMA
submittals.eLOMA requests that are audited by FEMA are processed within five business days of
receiving all of the required supporting data from the Licensed Professional.

Map Amendment.
Effect of LOMA or LOMR-F on Flood Insurance Requirements
The issuance of a LOMA or LOMR-F eliminates the Federal flood insurance purchase requirement
as a condition of Federal or federally backed financing;however,the mortgage lender retains the
prerogative to require flood insurance as a condition of providing financing,regardless of the location
of a structure. The purchase of a flood insurance policy is wise even if a structure is located outside
the SFHA. More than 25 percent of flood claims are made by property owners located outside the
SFHA.The 'issuance of a LOMA or LOMR-F does not mean the structure or lot is safe from all
flooding;it means that the risk of flooding is not as high as it is in the SFHA.Events greater than the
1-percent-annual-chance event can and do occur. It is also to important to note that the flood
insurance premium rate for structures located outside the SFHA are lower than the premiums for
structures located in the SFHA.

NFIP Map & Zone Grandfather Rules ,,--FLOOD
SURANCE PROGRAM
WHAT IS THE GRANDFATHER RULE?
A community will occasionally make structural improvements(dams, levees, etc.)to reduce the potential effects of
flooding;experience new development aggravating the flooding situation, thereby expanding the floodplain; revise
geographical boundaries resulting in the designation of additional flood hazard areas;or provide information to better
delineate the Base Flood Elevation (BFE) and/or flood insurance risk zones.When these situations occur,the Flood
Insurance Rate Map(FIRM) is revised and republished.
The implementation of a new FIRM raises the question-- HOW DOES THE NEW MAP AFFECT FLOOD INSURANCE RATES?
To recognize policyholders who have remained loyal customers of the NFIP by maintaining continuous coverage and/or
who have built in compliance with the FIRM,the Federal Emergency Management Agency has "Grandfather rules"to
allow such policyholders to benefit in the rating for that building.
PRE-FIRM (CONSTRUCTION PRIOR TO THE DATE OF THE COMMUNITY'S INITIAL FIRM OR PRIOR TO JANUARY 1,1975)
1. If a policy was obtained prior to the effective date of a map change,the policyholder is eligible to maintain the
prior zone and Base Flood Elevation as long as continuous coverage is maintained.The policy can be assigned to
a new owner at the option of the policyholder.
2. Exception: If the community's first FIRM was effective prior to January 1, 1975, and a building has not been
substantially damaged or improved since its original construction,the rates can be based on the FIRM zone
and/or the BFE on the FIRM in effect at the time of construction. In this case, proper documentation must be
provided. In all other instances, new policies for Pre-FIRM buildings must use the FIRM in effect when the
coverage is applied for.
POST-FIRM (CONSTRUCTION ON OR AFTER THE DATE OF THE COMMUNITY'S INITIAL FIRM)
1. If a policy was obtained prior to the effective date of a map change, the policyholder is eligible to maintain the
prior zone and base flood elevation as long as continuous coverage is maintained.The policy can be assigned to
a new owner at the option of the policyholder.
2. If a building was constructed in compliance with a specific FIRM,the owner is always eligible to obtain a policy
using the zone and Base Flood Elevation from that FIRM, provided that proof(refer to the Flood Insurance
Manual, Rating section for acceptable documentation) is submitted to the insurance company. Continuous
coverage is not required.
PREFERRED RISK POLICIES
1. Buildings written on Preferred Risk Policies are required to be located in zones B, C, or X on the FIRM in effect on
the date of application and on the date of each subsequent renewal.
2. A building, which becomes ineligible for a Preferred Risk Policy due to a map change to a Special Flood Hazard
Area, can be rewritten on a standard rated policy using zones B, C, or X.
