Guide for Community Officials (December 2009) 

Chapter 6 
Conditional Revisions 
and Amendments 

6.1 Background 
Communities, regional agencies, 
developers, and individual property owners 
often undertake floodplain modifications 
intended to reduce the flood risk in specific 
areas. Such modifications can range in 
scope from the simple placement of fill to 
large-scale flood protection projects to 
infrastructure improvements, such as 
bridge and road construction. Before 
proceeding with such modifications, those 
who propose them often wish to receive 
some assurance from FEMA that the 
modifications may eventually be credited 
with providing 1-percent-annual-chance 
flood protection under the National Flood 
Insurance Program (NFIP). 

In carrying out their responsibilities under 
the NFIP, community officials may wish to 
have FEMA verify that such modifications 
will not aggravate existing flood hazards. 
In addition, developers and property 
owners who intend to construct buildings 
in or near a Special Flood Hazard Area 
(SFHA) shown on an effective NFIP flood 
map usually must prove to lending 
institutions and local officials that the 
placement of fill or other modifications 
will ensure that, after the buildings are 
constructed, they will not be within the 
SFHA shown on the map. The SFHA is the 
area that would be inundated by the base 
(1-percent-annual-chance) flood. 

It is common practice for persons who are 
planning to undertake floodplain 
modifications to submit design plans and 

other engineering data to FEMA and 
request that FEMA review them. FEMA 
responses to such requests are to provide 
comments concerning changes that may 
eventually be made to the effective NFIP 
map. These comments are issued in the 
form of letters called Conditional Letters 
of Map Revision, or “CLOMRs.” 

Another common practice is for persons 
who are planning to place fill on single or 
multiple lots to request that FEMA 
determine whether the placement of fill 
will elevate their structure(s) above the 
Base (1-percent-annual-chance) Flood 
Elevation (BFE) determined by FEMA so 
that the structure(s) can, therefore, be 
considered as being outside the SFHA. 
FEMA responds to such requests with 
letters called Conditional Letters of Map 
Revision Based on Fill, or “CLOMR-Fs.” 

A less common practice is for persons who 
intend to build on single or multiple lots to 
request that FEMA determine whether the 
structure or structures, which will not be 
placed on fill, will be excluded from the 
SFHA as shown on the effective NFIP 
map. FEMA responds to such requests 
with letters called Conditional Letter of 
Map Amendments, or “CLOMAs.” 

With the exception of the federally funded 
flood protection systems that have met the 
requirements for “adequate progress” 
(Zone A99) discussed in Chapter 8 of this 
Guide and the flood protection systems 
that are being restored and meet the 
requirements for Zone AR discussed in 
Chapter 9 of this Guide, floodplain 
modifications that have not yet been 
completed do not warrant revisions to 
effective NFIP maps. Therefore, unlike 
Letters of Map Revision (LOMRs), Letters 
of Map Revision Based on Fill 

6-1 Conditional Revisions and Amendments 


Guide for Community Officials (December 2009) 

(LOMR-Fs), and Letters of Map 
Amendment (LOMAs), CLOMRs, 
CLOMR-Fs, and CLOMAs do not actually 
revise an effective NFIP map. Once a 
project is completed, it is the requester or 
community's responsibility to ensure that 
"as-built" information is submitted to 
FEMA for a LOMR, LOMR-F, or LOMA 
to be issued. 

The procedures that are followed in 
processing CLOMRs, CLOMR-Fs, and 
CLOMAs are presented in Figures 6-1, 
6-2, and 6-3, respectively, at the end of this 
chapter. 

6.2 Application Forms 
For communities that propose floodplain 
modifications, requesting CLOMRs is not 
only prudent but, in some circumstances, 
required by the NFIP regulations. (See 
Section 65.12 of the NFIP regulations.) 
When a participating community proposes 
to permit an encroachment into a 1percent-annual-chance floodplain where no 
regulatory floodway has been established, 
and the encroachment will cause an 
increase of more than 1.0 foot in the BFE 
(or less, if the State or community has a 
more restrictive standard for the allowable 
increase), the community must first obtain 
FEMA's conditional approval of the 
proposed encroachment under the 
conditional map revision process; 
Similarly, the community must also obtain 
conditional approval from FEMA before 
permitting an encroachment into a 
regulatory floodway that could cause any 
increase in flood elevation. 

In 1992, FEMA developed the MT-1 and 
MT-2 application forms to make the 
CLOMR, CLOMR-F, and CLOMA 

process quicker and more efficient. The 
MT-1 and MT-2 forms provide step-bystep instructions for requesters to follow 
and are comprehensive, ensuring that the 
requesters’ submissions are complete and 
more logically structured. This allows 
FEMA staff to complete their review 
quicker and at lower cost to the NFIP. 
While completing the forms may seem 
burdensome, experience has shown that the 
advantages to the requesters outweigh any 
inconvenience. These forms are discussed 
in more detail later in this chapter. 

6.3 Fee-Charge System 
To reduce the expenses to the NFIP by 
more fully recovering the costs associated 
with processing conditional and final map 
change requests, FEMA implemented a 
procedure to recover costs associated with 
reviewing and processing such requests. 
The fee schedule for CLOMR, CLOMR-F, 
and CLOMA requests and other map 
change requests is provided in Table D-1 
in Appendix D of this Guide. 

FEMA reviews its fee-charge procedures 
periodically (usually, once every 2 years) 
and may revise the review and processing 
fees for map change requests. Therefore, 
interested parties should visit the following 
page on the FEMA Website for the most 
up-to-date information: 

http://www.fema.gov/plan/prevent/fhm/fr 
m_fees.shtm. 

Certain map change requests may qualify 
for exemptions in accordance with Section 

72.5 of the NFIP regulations, as 
summarized on the above-referenced Web 
page and in Appendix D, and include 
changes that correct mapping errors, 
natural changes, and better quality data 
6-2 Conditional Revisions and Amendments 


Guide for Community Officials (December 2009) 

that do not partially or wholly incorporate 
manmade modifications within the SFHA. 

6.4 North American 
Vertical Datum of 1988 
Since the National Geodetic Survey 
determined that the national vertical 
control network needed to be readjusted, 
FEMA has been gradually converting 
NFIP maps from the National Geodetic 
Vertical Datum of 1929 (NGVD29) to the 
North American Vertical Datum of 1988 
(NAVD88) in the contiguous United 
States. Therefore, when submitting a 
CLOMR, CLOMR-F, or CLOMA request, 
requesters should use the reference datum 
shown on the applicable, effective 
FIRM/DFIRM panel(s). 

For more information on the conversion 
from NGVD29 to NAVD88, requesters 
should refer to FIA-20, Converting the 
National Flood Insurance Program to the 
North American Vertical Datum of 1988, 
Guidelines for Community Officials, 
Engineers, and Surveyors, and to 
Appendix B, “Guidance for Converting to 
the North American Vertical Datum of 
1988,” of FEMA’s Guidelines and 
Specifications for Flood Hazard Mapping 
Partners. These guidance documents are 
available from the FEMA Library 
(http://www.fema.gov/library/index.jsp). 
Information on how to obtain copies of 
these and other useful guidance documents 
is provided in Appendix B of this Guide. 

6.5 Endangered Species 
Act 
For conditional map change requests 
involving proposed projects that have the 

potential to impact an endangered species, 
the requester must submit documentation 
to show compliance with Sections 9 and 10 
of the Endangered Species Act. Section 9 
prohibits anyone from “taking” or harming 
an endangered species. If an action might 
harm an endangered species, a permit is 
required from U.S. Fish and Wildlife 
Service or National Marine Fisheries 
Service under Section 10 of the 
Endangered Species Act. 

In accordance with Subparagraph 
60.3(a)(2) of the NFIP regulations, FEMA 
will “review proposed development to 
assure that all necessary permits have been 
received from those governmental agencies 
from which approval is required by Federal 
or State law….” FEMA will work with the 
requester to ensure compliance with 
Endangered Species Act requirements for 
all conditional map change requests. 

6.6 How To Request a 
Conditional Letter of 
Map Revision 
A CLOMR may be requested at any time, 
either by a community or a private party. 
To request a CLOMR, the MT-2 
application forms package must be used. 

Requesters may obtain paper copies of 
these forms and instructions from the Map 
Specialists in the FEMA Map Assistance 
Center (FMAC). Requesters may contact 
the FMAC by telephone, toll free, at 
1-877-FEMA MAP (1-877-336-2627), or 
send an e-mail message to a FEMA Map 
Specialist at 
FEMAMapSpecialist@riskmapcds.com. 

Requesters also may download Word, 
PDF, and TXT versions of the MT-2 

6-3 Conditional Revisions and Amendments 


Guide for Community Officials (December 2009) 

application forms and instructions from the 
FEMA Library 
(http://www.fema.gov/library/index.jsp). 
The forms and instructions are accessible 
through the following page on the FEMA 
Website: 

http://www.fema.gov/plan/prevent/fhm/dl_ 
mt-2.shtm. 

Completed application forms, supporting 
data and documentation, and review and 
processing fees are to be submitted to the 
following address. 

LOMC Clearinghouse 

6730 Santa Barbara Court 

Elkridge, MD 21075 

Payment of the review and processing fee 
may be made by credit card, check, or 
money order. Checks and money orders 
are to be made payable in U.S. funds to the 
National Flood Insurance Program. If a 
revision requester chooses to use a credit 
card, the credit card information is to be 
provided on the “Payment Information 
Form” that is included in the MT-1 forms 
package. 

An assigned FEMA Fee-Charge System 
Administrator (FCSA) will review the 
check, money order, and payment 
information and, if appropriate, deposit the 
payment in the National Flood Insurance 
Fund (NFIF). If the FCSA identifies any 
irregularities with the payment, the FCSA 
will not deposit the payment in the NFIF. 
In such instances, FEMA will send a letter 
to the requester explaining any additional 
actions the requester must take to allow 
FEMA to process the request. 

Because the Chief Executive Officer 
(CEO) of the community is responsible for 
ensuring that the community meets its 
obligations as a participant in the NFIP, 

either the CEO or another community 
officially designated by the CEO (e.g., 
floodplain administrator [FPA], city 
planner, or city engineer) should be aware 
of proposed floodplain modifications that 
could eventually affect flooding conditions 
within the community. Therefore, any 
individual property owner, developer, or 
other private party who wishes to request a 
CLOMR should submit the request to the 
CEO or the designated community official. 

Upon completion of the community 
review, the CEO, FPA, or other designated 
official will forward the request to the 
office indicated in the application form 
instructions. 

6.7 Supporting Data and 
Documentation 
Required for 
Conditional Letters of 
Map Revision 
The main difference between the types of 
supporting data and documentation 
required for map revisions—Letters of 
Map Revision (LOMRs) and Physical Map 
Revisions (PMRs)—and those required for 
CLOMRs is that any maps, plans, 
drawings, measurements, or ground 
elevation data submitted in support of a 
request for a CLOMR will not reflect 
existing conditions and consequently 
cannot be certified " as-built." 

In addition, the operations and 
maintenance plans that are to be formally 
adopted by a community, which are part of 
the required supporting information for a 
map revision request based on the effects 
of a completed levee system or other flood 
protection system, are not required when a 

6-4 Conditional Revisions and Amendments 


Guide for Community Officials (December 2009) 

request is made for a CLOMR. (See 
Tables 4-1 through 4-4 in Chapter 4 of this 
Guide for summaries of the required data 
and documentation for a CLOMR.) 

As with LOMR and PMR requests, 
individuals or community officials that are 
considering whether to submit a CLOMR 
request also should refer to the MT-2 
instructions and the following forms, 
where appropriate, to clarify the supporting 
data and documentation required: 

• “Elevation Form” (Form 1); 
• “Riverine Hydrology & Hydraulics 
Form” (Form 2); 
• “Riverine Structures Form” 
(Form 3); 
• “Coastal Analysis Form” (Form 4); 
• “Coastal Structures Form” 
(Form 5); and 
• “Alluvial Fan Flooding Form” 
(Form 6). 
For most CLOMR requests, the data and 
documentation discussed below must be 
submitted. 

• Hydraulic modeling analysis of the 
floodplain and regulatory floodway 
(as appropriate) of all flood 
frequencies listed in the effective 
FIS report must be submitted. 
• A separate hydraulic analysis must 
be submitted duplicating the 
effective model and documenting 
proposed conditions though 
submission of a proposed-
conditions model. 
• To document any physical changes 
within a community’s floodplain 
since the effective model, it may be 
necessary for the CLOMR 
requester to provide an existing-
conditions model to accurately 
show the effects of a proposed 
project on a community’s flood 
levels. 
• Certified, dated, topographic work 
map, depicting scale, model cross-
sections, vertical datum reference, 
and contour interval (contour 
interval should be equivalent to or 
more detailed than that used to 
develop the effective Flood 
Insurance Rate Map (FIRM) or 
Digital Flood Insurance Rate Map 
(DFIRM) and delineating the flood 
zone and regulatory floodway 
boundaries (as appropriate) must be 
submitted. 
• A copy of the effective 
FIRM/DFIRM (panel number and 
effective date must be included in 
copy) annotated to reflect the 
proposed flood zone and regulatory 
floodway boundaries (as 
appropriate) must be submitted. 
• All appropriate completed 
certification forms including 
community concurrence of 
proposed revision are to be 
submitted. 
• Documentation showing 
compliance with Sections 9 and 10 
of the Endangered Species Act 
must be submitted. 
6-5 Conditional Revisions and Amendments 


Guide for Community Officials (December 2009) 

Certifications, where referenced in the 
requirements for supporting data and 
documentation, are defined as follows: 

• Certification of data is a statement 
that the data are accurate to the best 
of the certifier’s knowledge. 
• Certification of analyses is a 
statement that the analyses have 
been performed correctly and in 
accordance with sound engineering 
practices. 
• Certification of structural works is 
a statement that the works are 
designed in accordance with sound 
engineering practices to provide 
protection from the base flood. 
• Certification of as-built conditions 
is a statement that a structure has 
been built according to the plans 
being certified, is in place, and is 
fully functional. 
The CLOMR requester should ensure that 
certifications include the certifier’s name, 
signature, registration number, and the 
registration date of the certifier. 

6.8 Conditional Letter of 
Map Revision 
Processing Procedures 
As shown below and in Figure 6-1, which 
appears at the end of this chapter, the 
processing procedures for LOMR and 
PMR requests also apply to CLOMR 
requests. 

Although a CLOMR does not revise the 
effective Flood Insurance Study (FIS) 
report, FIRM, DFIRM or Flood Boundary 
and Floodway Map (FBFM), the CLOMR 
determination documents do describe 

changes to the effective FIS report, 
FIRM/DFIRM, or FBFM that will result 
from the project, if built as proposed. The 
CLOMR also describes any additional 
information (e.g., as-built plans, fill 
compaction certification) required by 
FEMA to process the final determination 
as a PMR or LOMR. 

For communities that propose floodplain 
modifications, requesting CLOMRs is not 
only prudent but, in some circumstances, 
required. (See Section 65.12 of the NFIP 
regulations.) When a participating 
community proposes to permit an 
encroachment into its 1-percent-annualchance floodplain where no floodway has 
been established, and the encroachment 
will cause an increase of more than 1.0 
foot in the BFE, the community must first 
obtain FEMA’s conditional approval of the 
proposed encroachment through the 
CLOMR process. Similarly, the 
community also must obtain conditional 
approval from FEMA before permitting an 
encroachment into a regulatory floodway 
that would result in any increases to flood 
levels. 

In their review of a map revision request, 
FEMA will acknowledge receipt of the 
request by letter and, if necessary, by 
telephone to the person who submitted the 
request. If that person is a private party, 
FEMA will send copies of all letters to that 
person to the community CEO(s) and 
FPA(s) of the affected community or 
communities. 

Upon receiving a CLOMR request, FEMA 
will perform a preliminary review to 
determine whether the requester has 
completed the appropriate forms; to 
determine whether the required supporting 
data and review and processing fee have 

6-6 Conditional Revisions and Amendments 


Guide for Community Officials (December 2009) 

been provided; and, if a private party 
submitted the request to FEMA, to verify 
that the community is aware of the request. 

If the required supporting data, 
documentation, forms, and/or review and 
processing fee have not been provided, 
FEMA will send a letter to the requester. 
This letter will identify the supporting 
data, documentation, forms, or review and 
processing fee that the requester must 
submit before FEMA can complete its 
review of the request. In this “additional 
data” letter, FEMA will also provide a 
timeframe (usually 90 days) for submitting 
the required data, documentation, forms, 
and/or fee. 

FEMA will generally send the additional 
data letter within 30 days. Until the 
requested data, documentation, forms, 
and/or fee are received, FEMA will not 
take any further action concerning the 
request. 

If FEMA determines from its preliminary 
review that the required forms and fee 
have been provided along with sufficient 
supporting data and documentation to 
complete its review, FEMA will then 
inform the requester of the amount of time 
that will be needed to complete its detailed 
review of the request (usually 30 to 90 
days). 

After completing its detailed review, 
FEMA will inform the requester by letter if 
any additional supporting data and/or 
documentation must be submitted before 
the CLOMR determination is issued. 
FEMA will always issue such letters 
within the 90-day period stipulated in the 
NFIP regulations, but will frequently send 
them within 30 days. Again, FEMA will 
take no further action on the request until 

the required supporting data and/or 
documentation are received. 

Upon receipt of all required data and 
documentation, FEMA will complete its 
review and will issue its determination 
regarding the CLOMR request in the form 
of a letter to the CEO(s) of the affected 
community or communities. FEMA will 
send copies of the letter(s) to the 
community FPA(s), other community 
official(s) who requested the CLOMR, and 
any individual non-community official 
requester(s). 

Samples of the CLOMR determination 
documents are provided in Appendix B of 
FEMA’s Document Control Procedures 
Manual, which is available from the 
FEMA Library 
(http://www.fema.gov/library/index.jsp). 
The Manual also can be accessed from a 
dedicated page on the FEMA Website: 

http://www.fema.gov/plan/prevent/fhm/gs_ 
dcpm.shtm. 

6.9 How To Request a 
Conditional Letter of 
Map Revision Based on 
Fill 
To request a CLOMR-F, the requester 
must complete the MT-1 application 
forms. Requesters may obtain paper copies 
of these forms and the step-by-step 
instructions from the Map Specialists in 
the FMAC. Requesters may contact the 
FMAC by telephone, toll free, at 
1-877-FEMA MAP (1-877-336-2627), or 
send an e-mail message to 
FEMAMapSpecialist@riskmapcds.com. 

Requesters also may download Word, 
PDF, and TXT versions of the MT-1

application forms and instructions from the 
FEMA Library; the forms and instructions 
are accessible through the following page 
on the FEMA Website: 

http://www.fema.gov/plan/prevent/fhm/dl_ 
mt-1.shtm. 

Completed application forms, supporting 
data and documentation, and review and 
processing fees for CLOMR-F requests are 
to be submitted to:

Elkridge, MD 21075 

6.10Supporting Data and 
Documentation 
Required for 
Conditional Letters of 
Map Revision Based on 
Fill 

The supporting data and documentation 
required for CLOMR-F are summarized 
below. The supporting data and 
documentation are the same as those 
required for LOMR-F requests; however, 
because CLOMR-F requests are based on 
proposed construction, as-built information 
is not required. 

• Property description documentation 
must be enclosed for every request 
and can consist of either the Plat 
Map or Deed (containing the 
recorder’s stamp and recordation 
date) accompanied by a tax 
assessor’s map or other suitable 
map showing the surveyed location 
of the property. 
Note: The recordation data (e.g., 
Book, Volume, Page, Reel, 

Document Number, Date) must 
appear on all documents submitted 
so that FEMA may use the legal 
description of the property in 
making its determination, and 
FEMA must be able to identify the 
property exactly. 

• If the property is not recorded on a 
Plat Map, a copy of the tax 
assessor’s map must be submitted 
to help FEMA located the property. 
• A photocopy of the effective 
FIRM/DFIRM panel, annotated to 
show where the property is located, 
must be submitted for every 
request. If FEMA has produced a 
separate FBFM for the area in 
which the structure(s) or parcel(s) 
of land may be located, a 
photocopy of the FBFM panel also 
should be included. The panel 
number and effective date of the 
FIRM/DFIRM and FBFM must 
appear on the copy submitted. The 
original paper copy of the map 
panel(s) or a photocopy of the map 
panels must be used. Due to 
possible distortion, a reproduction 
from a photocopy is unacceptable. 
• Elevation data must be submitted 
for all CLOMR-F requests. As 
discussed below, the type and 
source of the elevation data will 
vary. 
a. For riverine flood hazard areas, 
the BFE can be established by 
interpolation along the Flood 
Profile for the flooding source 
in the FIS report. If, for some 
reason, no Flood Profile exists, 
6-8 Conditional Revisions and Amendments 


Guide for Community Officials (December 2009) 

the BFE should be taken from 
the effective FIRM/DFIRM. 

b. For lacustrine flood hazard 
areas, the BFE can be taken 
from the Summary of Stillwater 
Elevations in the FIS report. If 
the flooding source is not 
included in the table, the BFE 
should be taken from the 
effective FIRM/DFIRM. 
c. For coastal flood hazard areas, 
the BFE should be taken from 
the effective FIRM/DFIRM and 
then compared with the 
elevation in the Summary of 
Stillwater Elevations table. If 
the stillwater elevation listed in 
the table is less than or equal to 
the whole-foot BFE shown on 
the map minus 0.5 foot, a wave 
height, wave runup, and/or 
wave setup component exists; 
therefore, the whole-foot BFE 
shown on the map should be 
used. If the stillwater elevation 
listed in the table is greater than 
the whole-foot BFE shown on 
the map minus 0.4 foot, the 
stillwater elevation shown in 
the table should be used as the 
BFE. 
d. For approximate flood hazard 
areas (designated Zone A on 
the map), FEMA has not 
determined BFEs. If a BFE for 
the area has not been developed 
by a Federal, State, or local 
government agency, the 
requester should refer to 
FEMA-265, Managing 
Floodplain Development in 
Approximate Zone A Areas: A 
Guide for Obtaining and 
Developing Base (100-Year) 
Flood Elevations, accessible 
through the FEMA Website 
(http://www.fema.gov/plan/pre 
vent/fhm/frm_docs.shtm). 

e. For shallow flooding areas 
(designated Zone AH on the 
map), the BFE shown on the 
effective FIRM/DFIRM should 
be used. 
f. For shallow/sheet flooding 
areas (designated Zone AO on 
the map), the characteristics of 
the area will determine the 
appropriate methodology, and 
the requester should refer to the 
guidance in the MT-EZ and 
MT-1 instructions. 
g. In addition to the BFE, the 
elevation data required for a 
structure is the Lowest 
Adjacent Grade (LAG) to the 
structure (i.e., the elevation of 
the lowest ground touching the 
structure, including attached 
decks or garage). 
h. The elevation data required for 
a legally defined parcel of land, 
or portion thereof, is the 
elevation of the lowest ground 
on the parcel or within the 
portion of land that is to be 
removed from the SFHA 
• Unless an NFIP Elevation 
Certificate has been completed for 
a proposed structure, the “Elevation 
Form” (Form 2) from the MT-1 
package must be completed and 
certified by a Licensed Land 
6-9 Conditional Revisions and Amendments 


Guide for Community Officials (December 2009) 

Surveyor or Registered 
Professional Engineer. 

• If an NFIP Elevation Certificate 
has been completed, it may be 
submitted in lieu of Form 2. The 
Elevation Certificate also must be 
certified by a Licensed Land 
Surveyor or Registered 
Professional Engineer. The 
Elevation Certificate is available 
through the FEMA Library and is 
accessible through the following 
page on the FEMA Website: 
http://www.fema.gov/plan/prevent/ 
fhm/frm_form.shtm. Paper copies 
of the Elevation Certificate also 
may be acquired by contacting the 
Map Specialists in the FMAC. 

• The “Community Acknowledgment 
Form” (Form 3) must be included 
for all CLOMR-F requests in which 
a property has been or will be 
inadvertently included within the 
regulatory floodway shown on the 
NFIP map; however, only Section 
A of Form 3 needs to be completed. 
• Documentation showing 
compliance with Sections 9 and 10 
of the Endangered Species Act 
must be submitted. 
For CLOMR-F requests involving property 
located in an area designated Zone A on 
the FIRM/DFIRM, with no BFEs 
determined, the requester should refer to 
FEMA-265, Managing Floodplain 
Development in Approximate Zone A 
Areas: A Guide for Obtaining and 
Developing Base (100-Year) Flood 
Elevations. This manual provides 
engineering guidelines for determining 
BFEs in Zone A areas and is accessible 

through the FEMA Website: 

http://www.fema.gov/plan/prevent/fhm/fr 
m_docs.shtm. 

Printed paper copies of the effective 
FIRM, DFIRM, and/or FBFM panel(s) and 
FIS report materials are kept on file in the 
Community Map Repository of each 
affected community. (Digital versions 
may also be available in some 
communities.) The Community Map 
Repository is the community office 
responsible for floodplain management 
activities in the community. 

Interested citizens who are having trouble 
locating the Community Map Repository 
may call a Map Specialist in the FMAC, 
toll free, at 1-877-FEMA MAP 
(1-877-336-2627), or send an e-mail to 
FEMAMapSpecialist@riskmapcds.com. 

To obtain their own digital copy of the 
complete effective NFIP map(s) or 
selected panel(s) and the FIS report, 
requesters should contact the MSC. The

6-10 Conditional Revisions and Amendments 


Guide for Community Officials (December 2009) 

For CLOMR-F requests affecting a single 
structure, a single lot, or multiple 
structures or lots in a relatively small area, 
requesters may also choose to create 
another product available from the MSC 
Website. This product is called a 
FIRMette. A FIRMette is a full-scale 
portion of particular map panel that a user 
creates by selecting a desired area from the 
online image of that map panel. In addition 
to the area of interest, the FIRMette 
includes the map title block, north arrow, 
and scale bar. There is no cost for 
producing a FIRMette. A FIRMette tutorial 
is available on the MSC Website to assist 
first-time users. 

Certifications, where referenced in the 
requirements for supporting data and 
documentation, are defined as follows: 

• Certification of data is a statement 
that the data are accurate to the best 
of the certifier’s knowledge. 
• Certification of analyses is a 
statement that the analyses have 
been performed correctly and in 
accordance with sound engineering 
practices. 
• Certification of structural works is 
a statement that the works are 
designed in accordance with sound 
engineering practices to provide 
protection from the base flood. 
The CLOMR-F requester should ensure 
that certifications include the certifier’s 
name, signature, registration number, and 
the registration date of the certifier. 

6.11Conditional Letter of 

Map Revision Based on 

Fill Processing 

Procedures 

The procedures that are followed in 
processing requests for CLOMR-Fs are 
shown in Figure 6-2 at the end of this 
chapter and are summarized below. 

After the CLOMR-F request has been 
received at the LOMC Clearinghouse 
mentioned earlier in this chapter, FEMA 
will review the submittal package for 
completeness and acknowledge receipt of 
the request by letter to the requester, 
usually within 10 days, but not later than 
60 days. This letter will identify any 
required supporting data, application 
forms, and/or fee that the requester did not 
submit and inform the requester to submit 
the required data, forms and other 
documentation, and/or fees within 90 days 
of the date of the letter. If the required 
supporting data, forms, documentation, 
and/or fee are not provided within 90 days, 
FEMA will suspend the processing of the 
request. 

If all required supporting data, forms, other 
documentation, and fee have been 
provided with the request, FEMA staff will 
acknowledge the request by letter and 
proceed with performing a technical 
review. If any questions or problems arise 
during this review, FEMA will work with 
the requester to resolve them appropriately. 

6-11 Conditional Revisions and Amendments 


Guide for Community Officials (December 2009) 

Once all required data, forms and other 
documentation, and fee are received, 
FEMA staff will complete their review and 
issue the appropriate conditional 
determination documents indicating: 

• The lot(s) would not be located in 
the SFHA if fill is placed as shown 
in the data and documentation 
provided by the requester. 
• The proposed structure(s) would 
not be located in the SFHA if the 
fill is placed and the proposed 
structure is/structures are built as 
shown in the data and 
documentation provided by the 
requester. 
• Neither the proposed structure(s) 
nor the lot(s) will be located in the 
SFHA if the fill is placed and the 
proposed structure is/structures are 
built as shown in the data and 
documentation provided by the 
requester. 
• The proposed structure(s) will not 
be located in the SFHA, but the 
lot(s) will be located in the SFHA 
if the fill is placed and the structure 
is/structures are built as shown in 
the data and documentation 
provided by the requester. 
Samples of the CLOMR-F determination 
documents are provided in Appendix C of 
FEMA’s Document Control Procedures 
Manual, which is available in the FEMA 
Library 
(http://www.fema.gov/library/index.jsp) . 
The Manual also can be accessed from the 
following page on the FEMA Website: 

http://www.fema.gov/plan/prevent/fhm/gs_ 
dcpm.shtm. 

As provided for in the NFIP regulations, 
FEMA must complete the processing of 
CLOMR-F requests within 60 days of the 
date that all required supporting data and 
documentation are received. However, 
FEMA generally issues determinations for 
CLOMR-Fs within 4 weeks of the date that 
all required supporting data and 
documentation are received. 

As discussed earlier in this Guide, a 
CLOMR-F does not revise the effective 
FIRM or DFIRM panel(s) for the 
community, structure(s), and lot(s) that are 
the subject of the request. 

6.12How To Request a 

Conditional Letter of 

Map Amendment 

To request a CLOMA, the requester must 
complete the MT-1 application forms. 
Requesters may obtain paper copies of 
these forms and the step-by-step 
instructions from the Map Specialists in 
the FMAC. Requesters may contact the 
FMAC by telephone, toll free, at 
1-877-FEMA MAP (1-877-336-2627), or 
send an e-mail message to 
FEMAMapSpecialist@riskmapcds.com. 

Requesters also may download Word, 
PDF, and TXT versions of the MT-1 
application forms and instructions from the 
FEMA. The forms and instructions also are 
accessible through the following page on 
the FEMA Website: 

http://www.fema.gov/plan/prevent/fhm/dl_ 
mt-1.shtm. 

6-12 Conditional Revisions and Amendments 


Guide for Community Officials (December 2009) 

Completed application forms, supporting 
data and documentation, and review and 
processing fees for CLOMA requests are 
to be submitted to: 

LOMC Clearinghouse 

6730 Santa Barbara Court 

Elkridge, MD 21075 

6.13Supporting Data and 

Documentation 

Required for 

Conditional Letters of 

Map Amendment 

The supporting data and documentation 
required for CLOMA requests are 
summarized below. The supporting data 
and documentation are the same as those 
required for LOMA requests; however, 
because LOMAs requests are based on 
proposed construction, as-built information 
is not required. 

Under the conditional map amendment 
process, FEMA will make determinations 
for single or multiple proposed structures 
on one or more lots and for single or 
multiple parcels of land that can be legally 
described. The supporting data and 
documentation summarized below are to 
be submitted in support of a CLOMA 
request. 

• Property description documentation 
must be enclosed for every request 
and can consist of either the Plat 
Map or Deed (containing the 
recorder’s stamp and recordation 
date) accompanied by a tax 
assessor’s map or other suitable 
map showing the surveyed location 
of the property. Note: The 
recordation data (e.g., Book, 
Volume, Page, Reel, Document 
Number, Date) must appear on all 
documents submitted so that 
FEMA may use the legal 
description of the property in 
making its determination, and 
FEMA must be able to identify the 
property exactly. 

• If the property is not recorded on a 
Plat Map, a copy of the tax 
assessor’s map must be submitted 
to help FEMA located the property. 
• A photocopy of the effective 
FIRM/DFIRM panel, annotated to 
show where the property is located, 
must be submitted for every 
request. If FEMA has produced a 
separate Flood Boundary and 
Floodway Map (FBFM) for the 
area in which the structure(s) or 
parcel(s) of land may be located, a 
photocopy of the FBFM panel also 
should be included. The panel 
number and effective date of the 
FIRM/DFIRM and FBFM must 
appear on the copy submitted. The 
original paper copy of the map 
panel(s) or a photocopy of the map 
panels must be used. A 
reproduction from a photocopy is 
unacceptable due to possible 
distortion. 
• Elevation data must be submitted 
for all requests, except requests for 
determinations in which the 
effective FIRM/DFIRM already 
shows the property to be clearly 
outside the SFHA. As discussed 
below, the type and source of the 
elevation data will vary. 
6-13 Conditional Revisions and Amendments 


Guide for Community Officials (December 2009) 

a. For riverine flood hazard areas, 
the BFE can be established by 
interpolation along the Flood 
Profile for the flooding source 
that appears in the FIS report. 
If, for some reason, no Flood 
Profile exists, the BFE should 
be taken from the effective 
FIRM/DFIRM. 
b. For lacustrine flood hazard 
areas, the BFE can be taken 
from the Summary of Stillwater 
Elevations in the FIS report. If 
the flooding source is not 
included in the table, the BFE 
should be taken from the 
effective FIRM/DFIRM. 
c. For coastal flood hazard areas, 
the BFE should be taken from 
the effective FIRM/DFIRM and 
then compared with the 
elevation in the Summary of 
Stillwater Elevations table. If 
the stillwater elevation listed in 
the table is less than or equal to 
the whole-foot BFE shown on 
the map minus 0.5 foot, a wave 
height, wave runup, and/or 
wave setup component exists; 
therefore, the whole-foot BFE 
shown on the map should be 
used. If the stillwater elevation 
listed in the table is greater than 
the whole-foot BFE shown on 
the map minus 0.4 foot, the 
stillwater elevation shown in 
the table should be used as the 
BFE. 
d. For approximate flood hazard 
areas (designated Zone A on 
the map), FEMA has not 
determined BFEs. If a BFE for 
the area has not been developed 
by a Federal, State, or local 
government agency, the 
requester should refer to 
FEMA-265, Managing 
Floodplain Development in 
Approximate Zone A Areas: A 
Guide for Obtaining and 
Developing Base (100-Year) 
Flood Elevations, which is 
accessible through the FEMA 
Website: 
http://www.fema.gov/plan/prev 
ent/fhm/frm_docs.shtm. 

e. For shallow flooding areas 
(designated Zone AH on the 
map), the BFE shown on the 
effective FIRM/DFIRM should 
be used. 
f. For shallow/sheet flooding 
areas (designated Zone AO on 
the map), the characteristics of 
the area will determine the 
appropriate methodology, and 
the requester should refer to the 
guidance in the MT-EZ and 
MT-1 instructions. 
g. In addition to the BFE, the 
elevation data required for a 
structure is the Lowest 
Adjacent Grade (LAG) to the 
structure (i.e., the elevation of 
the lowest ground touching the 
structure, including attached 
decks or garage). 
6-14 Conditional Revisions and Amendments 


Guide for Community Officials (December 2009) 

h. The elevation data required for 
a legally defined parcel of land, 
or portion thereof, is the 
elevation of the lowest ground 
on the parcel or within the 
portion of land that is to be 
removed from the SFHA. 
• For all requests except requests for 
determinations in which the 
effective FIRM/DFIRM already 
shows the property to be clearly 
outside the SFHA, the “Elevation 
Form” (Form 2) from the MT-1 
package must be included unless an 
NFIP Elevation Certificate (EC) 
has been completed. The elevation 
data must be certified by a 
Licensed Land Surveyor or 
Registered Professional Engineer. 
• If an EC has been completed for 
the proposed structure(s), the EC 
may be submitted in lieu of Form 2. 
The EC(s) also must be certified by 
a Licensed Land Surveyor or 
Registered Professional Engineer. 
The EC is available through the 
FEMA Library and can be accessed 
through the following page on the 
FEMA Website: 
http://www.fema.gov/plan/prevent/ 
fhm/frm_form.shtm. Paper copies 
of the EC form also may be 
acquired by contacting the Map 
Specialists in the FMAC. 

• Documentation showing 
compliance with Sections 9 and 10 
of the Endangered Species Act 
must be submitted. 
Printed paper copies of the effective 
FIRM, DFIRM, and/or FBFM panel(s) and 
FIS report materials are kept on file in the 
Community Map Repository of each 
affected community. (Digital versions 
may also be available in some 
communities.) The Community Map 
Repository is the community office 
responsible for floodplain management 
activities in the community. Interested 
citizens who are having trouble locating 
the Community Map Repository may call a 
Map Specialist in the FMAC, toll free, at 
1-877-FEMA MAP (1-877-336-2627), or 
send an e-mail to 
FEMAMapSpecialist@riskmapcds.com. 

To obtain their own digital copy of the 
effective NFIP map(s) or selected panel(s) 
and the FIS report, CLOMA requesters 
should contact the MSC. The effective 
NFIP maps may be viewed online through 
the MSC Website: 
http://www.msc.fema.gov/. Effective 
NFIP maps, FIS reports, and related 
products also may be downloaded for a 
nominal fee from the MSC Website. 
(Effective October 1, 2009, the MSC 
distributes only digital versions of the 
flood maps and FIS reports.) A screen shot 
of the MSC Home Page is provided in 
Appendix B of this Guide. 

Individuals who do not have Internet 
access or who require additional assistance 
also may contact the MSC staff by 
telephone, toll free, at 1-800-358-9616, or 
by facsimile transmission, toll free, at

For many CLOMA requests, particularly 
those involving single structures, single 
lots, or multiple lots and structures 
occupying a relatively small area, 
requesters may also choose to create 
another product available from the MSC 
Website. This product is called a 
FIRMette. 

A FIRMette is a full-sized section of 
particular map panel that a user creates by 
selecting a desired area from the online 
image of that map panel. In addition to the 
area of interest, the FIRMette includes the 
map title block, north arrow, and scale bar. 
FEMA does not charge a fee for producing 
a FIRMette. To assist first-time users, the 
MSC has produced a FIRMette tutorial, 
which also is available on the MSC 
Website. 

Certifications, where referenced in the 
requirements for supporting data and 
documentation, are defined as follows: 

• Certification of data is a statement 
that the data are accurate to the best 
of the certifier’s knowledge. 
• Certification of analyses is a 
statement that the analyses have 
been performed correctly and in 
accordance with sound engineering 
practices. 
• Certification of structural works is 
a statement that the works are 
designed in accordance with sound 
engineering practices to provide 
protection from the base flood. 
The CLOMA requester should ensure that 
certifications include the certifier’s name, 
signature, registration number, and the 
registration date of the certifier. 

6.14 Conditional Letter of 
Map Amendment 
Processing Procedures 
After the request has been received, FEMA 
will acknowledge receipt of the request by 
letter to the requester, usually within 10 
days, but not later than 60 days. This letter 
will identify any basic data or 
documentation that the requester may have 
neglected to submit. If sufficient data have 
been provided with the request, FEMA 
will review the request and the supporting 
data and/or documentation. If any 
questions or problems arise during this 
review, FEMA will work with the 
requester to resolve them. If these required 
data and/or documentation are not 
provided within 90 days, FEMA will 
generally suspend the processing of the 
request. 

As provided for in the NFIP regulations, 
FEMA must complete the processing of 
CLOMA requests within 60 days of the 
date that all required supporting data and 
documentation are received. However, 
FEMA generally issues determinations for 
CLOMAs within 4 weeks of the date that 
all required supporting data and 
documentation are received. 

6-16 Conditional Revisions and Amendments 


Guide for Community Officials (December 2009) 

Once all required data and documentation, 
including application forms, are provided, 
FEMA will complete its review and issue 
one of the determinations below as 
appropriate: 

• The proposed structure(s) and lot(s) 
are/will be out of the SFHA as 
shown on the effective NFIP map. 
No amendment to the map will be 
necessary. 
• The proposed structure(s) and lot(s) 
will be out of the SFHA because 
the proposed structure(s) or lot(s) 
will be above the BFE. 
• The proposed structure(s) and lot(s) 
will be in the SFHA because the 
proposed structure(s) or lot(s) will 
be below the BFE. 
• The proposed structure(s) will be 
above the BFE and therefore out of 
the SFHA. However, the remainder 
of the lot(s) will continue to be in 
the SFHA. 
Samples of the CLOMA determination 
documents are provided in Appendix C of 
FEMA’s Document Control Procedures 
Manual, which is available in the FEMA 
Library
