Mandatory Flood Insurance Purchase in Remapped Residual Risk Areas Behind Levees
Summary
This report examines the amount of flood insurance that must be purchased (and retained) on
loans secured by real property located in federally designated special flood hazard areas (SFHAs).
It is written in response to three situations: (1) the Federal Emergency Management Agency’s
remapping efforts that include verifying the status of all levees as providing protection against a
100-year flood, which are currently depicted on Flood Insurance Rate Maps, and widespread
concerns among homeowners about new requirements to purchase flood insurance should the
levee become decertified; (2) uncertainty as to whether the mandatory amount of flood insurance
should be equal to the assessed value of the insured residential structure or the unpaid principal
balance (UPB) of the mortgage loan; and (3) concerns that homeowners may be inappropriately
asked to purchase an amount of flood insurance that is several times the value of the actual
property. This report will be updated as events warrant.

Mandatory Flood Insurance Purchase in Remapped Residual Risk Areas Behind Levees
Introduction
This report examines the federal government’s efforts to conduct a nationwide Flood Insurance
Study (FIS) to obtain new flood-hazard data, publish more accurate, up-to-date flood-risk
assessments and maps, and to require more homeowners to buy flood insurance if they live
behind dams or levees. As part of the Federal Emergency Management Agency’s (FEMA) map
modernization program, the agency has implemented a policy to verify the certification status of
all levees currently depicted on flood insurance rate maps (FIRMs). Currently, if FEMA agrees
that a levee shown on a government-issued FIRM can withstand a 100-year flood—that is, a flood
that has only a 1% chance of happening in any given year—then the homes and businesses
protected by the levee are not considered to be in the floodplain.1 This means homeowners living
there do not have to buy federal flood insurance. Homeowners may be affected if FEMA
decertifies the levee.
The National Flood Insurance Program
Floods and severe storms are among the most costly kind of weather and climate disaster in the
United States. The standard homeowners insurance policy generally excludes losses caused by
flood. This gap in coverage is usually filled with the purchase of flood insurance from the
National Flood Insurance Program (NFIP) in communities where certain required flood control
activities have been undertaken. In 1968, Congress established the NFIP to provide insurance for
property damage due to flooding. The NFIP remains the regime in which the federal government
provides insurance, maps the floodplains, and oversees the national regulation of the land use
ordinances.
Under the NFIP, the federal government makes subsidized flood insurance available to
homeowners through a network of private insurance companies (called Write-Your-Own
companies) in communities that agree to implement and enforce minimum national standards for
regulating new development in floodplains. Land use controls are usually adopted to steer new
construction away from high-risk locations and to otherwise mitigate construction in hazardous
zones.
In addition, the federal government studies flood hazards and publishes floodplain maps that
show the probability of flooding in a particular area within 100 years. This regulatory standard
then requires raising of the first floor of new construction above the elevation of the 100-year
storm. In the highest-risk zones, where water moves with velocity, there would normally be no
construction, and any new construction would not get the subsidized rates but would pay full
actuarial rates. Lenders are required to protect the collateral (the structure) with flood insurance if
the mortgage is federally guaranteed and the structure is in a high-risk flood zone.
1 The 100-year concept is a probabilistic standard for an area within a floodplain that has a 1% or greater chance of
flood occurrence within a given year. Such an event could actually happen twice in a year, while the average
occurrence remains only once in a century.

Flood Insurance, Maps, and Floodplain Management
In the wake of Hurricane Katrina in 2005, three sets of problems have emerged with respect to
flood maps, the insurance program, and the increased frequency of extreme weather events across
the country, along with increased likelihood of devastating floods, including the Midwest flood in
2008.
• Recent catastrophic flooding revealed that FEMA floodplain maps were
sometimes over 20 years old and seriously outdated, based on old evaluations of
levees and river conditions.
• Losses from major floods have been compounded by over-reliance on levees and
other strategies for taming rivers, which encouraged development in flood-prone
areas. Rivers and streams have been increasingly altered by dams, levees, and
other structures intended to increase inland navigation and flood control. In some
cases, levees built 50 years ago for agricultural purposes are now expected to
function as a residential or urban levee. Floods in 1993 and 2008 breached or
topped these levees, which were not built to handle such floods of historic
proportions.
• Experts generally agree on a need to expand to “residual risk” areas the
requirement that lenders require borrowers to purchase flood insurance. These are
areas that are subject to flooding by the 0.2%-annual chance flood (500-year
flood), areas subject to coastal storm surge floods, and areas that would be
subject to flooding but for the presence of flood control structures such as levees,
dams, and other man-made structures—the so-called “natural 100-year
floodplain.”
The 111th Congress could opt to consider various comprehensive proposals to reform
and modernize the NFIP.2 A key part of that reevaluation would likely be the costs of
floodplain remapping and expanding mandatory flood insurance purchase
requirements to 500-year flood zones.
Flood Risk Assessment and Mapping
As part of its administration of the NFIP, FEMA identifies the nation’s flood risks, establishes
appropriate risk zone determinations, and reflects these determinations accurately on FIRMs.
Flood maps generally delineate both high-risk zones, called special flood hazard areas (SFHAs),3
and low-to-moderate risk zones with a less than 1% annual chance of flooding. FEMA maintains
an inventory of roughly 106,000 maps. Accuracy is an essential component of the NFIP, and this
requires the updating of maps to reflect natural and human-induced changes in the land surface
within the floodplains. Flood maps serve a wide range of uses, including local planning,
emergency preparedness and response, and natural resource management. FIRMs are also used by
lending institutions and insurance companies to calculate flood insurance rates and establish who
is required to comply with mandatory flood insurance purchase requirements.
2 See CRS Report R40650, National Flood Insurance Program: Background, Challenges, and Financial Status , by
Rawle O. King.
3 Special Flood Hazard Areas (SFHAs) are defined as land areas on the FIRMs that are subject to inundation by a flood
that has a 1% probability of being equaled or exceeded in any given year.

Mandatory Flood Insurance Purchase in Remapped Residual Risk Areas Behind Levees
According to the Government Accountability Office, 50% of the NFIP’s roughly 106,000 maps
were more than 15 years old in April 2008, and another 8% were 10 to 15 years old.4 Outdated
flood maps could give homeowners a false sense of security since the maps might not show their
property being located in a flood risk zone. Developers could construct properties in flood risk
areas not identified on outdated or inaccurate flood maps. Finally, outdated flood maps impair the
actuarial soundness of the FEMA’s flood insurance program.
In 2003, at the urging of Congress and in collaboration with state and local partners, FEMA
launched a five-year public awareness and map modernization program (Map Mod) to convert
existing paper FIRMs into more accurate digital flood insurance rate maps (DFIRMs).5 In 2005,
acting on direction from Congress and feedback from the U.S. Government Accountability
Office, the Department of Homeland Security’s Inspector General, and other stakeholders, FEMA
undertook a mid-course evaluation of its flood map modernization program.6 This comprehensive
evaluation found that there was a need for greater flexibility in determining flood areas to be
mapped, particularly areas behind levees.
A key challenge in Map Mod has been to obtain high-accuracy digital land-surface elevation data.
A solution was light detection and ranging (LIDAR) technology, which is based on remote-
sensing laser measurements collected from aircraft. Both sets of data—base map imagery and
base flood elevation data—are imputed into the National Elevation Dataset that the U.S.
Geological Survey (USGS) maintains in support of FEMA’s flood map modernization goals.
As part of the Map Mod program, FEMA initiated a nationwide flood insurance study (FIS) to
update flood-hazard data and to reflect accurately the flood hazard and risk in “levee-impacted”
areas on DFIRM. According to FEMA, the primary goals of the FIS and DFIRM are to (1)
incorporate available updated flood hazard information, as well as revisions effected by letters of
map revisions (LOMRs) issued by FEMA since the latest FIS reports and FIRMs were published;
(2) convert the base flood elevation data from the National Geodetic Vertical Datum of 1929 to
the North American Vertical Datum of 1988; and (3) upgrade the FIRMs to a geographic
information system (GIS) database format to set the stage for follow-up detailed engineering
studies and restudies and to enable support for GIS analyses and other digital applications.
Residual Flood Risk of Levees
As part of FEMA’s Map Mod program, FEMA has also implemented a policy to verify the
certification status of all levees currently depicted on FIRMs as meeting design, operation, and
maintenance standards for protection against the 1%-annual-chance flood.
The regulatory requirements for accrediting levees as providing base flood protection on FIRMs
are found in Title 44 of the Code of Federal Regulations (CFR), Section 65.10 (44 CFR 65.10).

5 The three components of the DFIRMs are (1) the base map imagery that provides land surface information such as
location of streams, roads, and buildings; (2) base elevation data which is superimposed on top of the land surface
information to provide 3-dimensional information; and (3) engineering analysis such as data and models of stream and
river flows. Base map imagery is generally obtained from aerial and satellite photographs.

Mandatory Flood Insurance Purchase in Remapped Residual Risk Areas Behind Levees
These criteria include design criteria (e.g., freeboard, closures, embankment protection,
embankment and foundation stability, settlement, interior drainage), operation, and maintenance.
FEMA has specified levees to be built to withstand storm surges that rise three feet above the
base flood elevation.
On August 22, 2005, FEMA issued Procedure Memorandum No. 34 to clarify that it is the
community or levee system owner’s responsibility to provide data and documentation to show
that a levee system meets 44 CFR Section 65.10 requirements.7 A levee accreditation designation
allows a community and its structures to be removed from SFHA status. Levee accreditation
means a community could be exempt from both flood insurance purchase requirements and local
land-use restrictions.
Technical Criteria for Levee Certification
FEMA does not conduct a detailed physical inspection of levees to determine whether and how
the flood control project or system will perform in a flood event. Rather, officials from FEMA’s
regional office typically meet with county and local community officials to put together a levee
accreditation plan that outlines a process and time line to submit the levee certification data to
FEMA that coincides with FIS and DFIRM schedules for the county.
For a levee system to become accredited, the community or levee owner seeking recognition must
provide FEMA with certain data and documentation showing that the levee is (1) designed to
withstand forces associated with the 1% annual chance flood (height, stability, and embankment
protection); (2) adequate in terms of freeboard (e.g., minimum levee height is 3-4 feet above
design flood state); (3) all closure devices function property; (4) operation and maintenance plans
are adequate and in place; and (5) interior drainage systems (pumps and canals) are functioning.
The documentation for accreditation is usually prepared by a registered professional engineer
who knows FEMA’s flood insurance study guidelines or by a federal agency (e.g., the U.S. Army
Corps of Engineers (USACE)) with levee design and construction qualifications.
FEMA’s accreditation is not a guarantee of performance of the levee. It is only a statement that
data and documentation submitted to the agency is accurate and the analysis and design were
performed correctly and in accordance with sound engineering practices and FEMA guidelines.8
If a levee is not certified, FEMA has the power to designate the area protected by the levee as
being in a SFHA, which forces homeowners in the residual risk area to purchase flood insurance
as a condition of receiving a federally insured mortgage. Non-accredited levees are shown on
flood maps as not providing protection from a base flood.
Provisionally Accredited Levee Systems9
FEMA’s accreditation criteria are fairly direct. Communities and levee owners either provide all
data to support that a given levee system complies with the requirements in 44 CFR 65.10—or
they do not.10

Mandatory Flood Insurance Purchase in Remapped Residual Risk Areas Behind Levees
To minimize the impact of mapping areas behind levees on the Map Mod goals, FEMA issued on
September 25, 2006, Procedure Memorandum No. 43, “Guidelines for Identifying Provisionally
Accredited Levees,” to provide guidance on issuing preliminary and final effective DFIRMs,
while providing communities/levee system owners with 24 months to compile and submit the
data and documentation required to show compliance with 44 CFR Section 65.10. PM No. 43
established the concept of Provisionally Accredited Levee (PAL) systems.11 On March 16, 2007,
FEMA issued a revised version of PM No. 43 to clarify the procedures that FEMA and its
mapping partners are to follow for federal and non-federal levee projects.
FEMA has essentially given levee owners additional time to submit evidence of the levee’s status.
In order for a levee to be provisionally accredited, the community or levee owner must commit to
FEMA in writing to submit the full Section 65.10 compliance documentation for the levee within
24 months of the signed agreement. During the 24-month period of PAL, areas behind the levee
are mapped as having a moderate flood risk and designated as a PAL. If, however, the area does
not meet FEMA’s criteria, the map will show the area as a high-risk zone, or a SFHA.
The 24-month PAL period has now expired for most communities. This situation presents a
challenge for many local community residents and local officials, as well as their congressional
representatives. Some Members of Congress have considered legislative options to extend the 24-
month PAL period. Others have proposed providing explicit federal funding to local communities
to fund the cost of securing FEMA accreditation.
On April 24, 2009, FEMA issued Procedural Memorandum 53, “Guidelines for Notifying and
Mapping of Expiring Provisional Accredited Levee Designations,” that provides guidelines for
notification of communities/levee system owners regarding expiring PAL designations and for
mapping of accredited and de-accredited levee-impacted areas after the PAL period expiration.12
Under the new guidelines, FEMA’s regional offices will send out (during the 24-month PAL
period), two letters—90 days and 30 days before expiration—to the chief executive officer of all
affected communities, as well as to the state levee safety official, the USACE district office, and
the district offices of U.S. senators and representatives in those affected areas. FEMA’s regional
offices are authorized to determine if the PAL system will be accredited or de-accredited. FEMA
must begin a remapping of the area immediately upon determining that the PAL system is to be
accredited or de-accredited. This process must last at least 18 months before a preliminary
DFIRM can be issued that reflects either the newly designated accredited or de-accredited levee
system.13
FEMA will not grant an extension to the 24-month PAL period. However, PM No. 53 outlines
procedures that essentially allow communities and levee system owners additional time to
provide the 44 CFR Section 65.10 compliance data and documentation submittals to FEMA
before the DFIRM is final and becomes effective.

Mandatory Purchase Requirements
Under the National Flood Insurance Act of 1968,14 as amended by the Flood Disaster Protection
Act of 197315 and the National Flood Insurance Reform Act of 199416 regulated lending
institutions,17 federal agencies,18 and secondary market entities19 involved in mortgage loan
transactions cannot make, increase, extend, or renew any loan secured by improved real estate or
a mobile home in any area that has been designated by the Administrator of FEMA as a SFHA
unless the building or mobile home or any personal property securing the loan is covered by the
required amount of flood insurance.
If the property is not located in an SFHA, but instead in a low-to-moderate flood risk area, federal
law does not require flood insurance; however, it is recommended since historically about one in
four flood claims have come from these low-to-moderate risk areas. In addition, the mandatory
flood insurance purchase requirement does not apply to loans on state-owned property covered
under an adequate policy of self-insurance satisfactory to the Administrator of FEMA or to loans
with an original principal balance of $5,000 or less, and having an original repayment term of one
year or less.
Pursuant to federal flood insurance laws and regulations, the amount of flood insurance that must
be purchased depends on several factors, primarily the amount of financial assistance,20 the
unpaid principal balance (UPB) on loans secured by real property in an SFHA, and the maximum
amount of insurance available through NFIP.21 The formula for determining the correct amount of
flood insurance is fairly straightforward, but in practice it has generated considerable ambiguity
and confusion among financial institutions, particularly as it relates to determining the “insurable
value” of the building using the new FEMA guidelines that imposes a claims recovery limit
standard of 100% replacement cost value (RCV).22 The old FEMA guidelines are based on
appraised value minus the value of the land.

bank association, production credit association, or similar institutions subject to the supervision of a federal financial
regulatory agencies including the Board of Governors of the Federal Reserve system (FED), the Farm Credit
Administration (FCA), Federal Deposit Insurance Corporation (FDIC), National Credit Union Administration (NCUA),
Office of the Comptroller of the Currency (OCC), and the Office of Thrift Supervision (OTS).
18 The federal agencies are: Small Business Administration (SBA), Veterans Administration, and Federal Housing
Administration (FHA).
19 Federal National Mortgage Association (Fannie Mae), the Federal Home Loan Mortgage Corporation (Freddie Mac)
and the Government National Mortgage Association (Ginnie Mae) are considered federal agencies for purposes of
flood insurance and are often referred to as government-sponsored enterprises (GSEs). These organizations support
residential housing ownership by providing liquidity to the residential mortgage market. Congress did not make the
Federal Agriculture Mortgage Corporation (Farmer Mac), another GSE, subject to flood insurance requirements.
20 Financial assistance means any form of direct, insured, or guaranteed loan, any form of grant, or any form of direct
or indirect assistance extended by a federal agency.
21 For single-family and two-to-four family dwellings, the maximum amount of flood insurance available under the
NFIP is $250,000; up to $500,000 in coverage is available for nonresidential buildings.

Mandatory Flood Insurance Purchase in Remapped Residual Risk Areas Behind Levees
Despite efforts by FEMA to clarify the definition of the mandatory flood insurance purchase
requirement, considerable confusion still exists among lenders. FEMA recommends that lenders
seek guidance from financial institution regulatory authorities with respect to determining
insurable value. The problem is that neither the 1973 and 1994 Acts (see Appendix A) nor
NFIP’s implementing regulations defines the term “insurable value.” Consequently, there are
inconsistencies in how the insurable value is determined by the various lenders and the amount
that a borrower could possibly collect under a General Property Form which is used in insuring
non-residential structures.23 Definitions used by lenders vary; some define the insurable value as
“appraised value minus land” while others refer to it as “100% of the full replacement cost value
(RCV) including the supporting structure.” One may argue that there is a need for one
consistently applied standard for determining the insurable value. This issue is being addressed by
the new guidance, “Loans in Areas Having Special Flood Hazards: Interagency Questions and
Answers Regarding Flood Insurance” (Flood Q&A), published by the federal financial regulatory
agencies (see discussion in Appendix A).
The September 2007 “Mandatory Purchase of Flood Insurance Guidelines” (FEMA guidelines)
were designed to address the ambiguities in determining the appropriate flood insurance purchase
obligations.24 However, the new reference in the FEMA guidelines to 100% RCV in the context
of NFIP’s recovery limits on the NFIP’s Standard Flood Insurance Policy (SFIP) has raised
questions from lenders on how to determine RCV when calculating the amount of insurance that
must be obtained. Although federal law and regulation impose a minimum amount of flood
insurance that each loan must have, it does not prevent lenders from requiring that each loan be
insured up to the NFIP’s recovery limits (100% RCV) subject to the maximum coverage available
through the program. Lenders can also require that personal property within a structure located in
a SHFA be insured if the property secures all or part of a loan.
Determining the Appropriate Amount of Flood Insurance
The NFIP Guidelines require flood insurance to be purchased in an amount equal to the lesser of
• the maximum amount of coverage available for the type of building,
• the outstanding principal balance of the loan, or
• the full insurable value of the property, which is the same as 100% of the
replacement cost value (excluding the appraised value of the land).25
The NFIP pays flood damage losses on the basis of replacement cost value for primary residences
where the insured has purchased insurance of up to at least 80% of the replacement cost of the
structure.26 This is done to ensure sufficient resources to pay the full cost of repair or replacement
23 There are three different NFIP coverage forms—the general property form, the residential condominium association
policy, and the dwelling form. The general property form covers other residential buildings of five families or more and
nonresidential buildings. The residential condominium association policy covers the common elements and all
structural items of the condominium units within a building. It also covers contents owned in common. The dwelling
form can be used to cover single-family and multi-family dwellings.

without deduction for depreciation. The various federal agencies that oversee lending institutions
generally follow FEMA’s Purchase of Flood Insurance Guidelines (including recovery limits) but
are free to develop their own regulations.
For practical purposes, however, given Fannie Mae’s traditional role as a major secondary market
for residential mortgages, most mortgage lenders usually follow Fannie Mae’s guidance when
calculating the amount of insurance that must be obtained. According to Fannie Mae,
“replacement cost value” refers to the cost of rebuilding a damaged property of the same size with
the same amenities as the original structure. Fannie Mae requires that flood insurance for a first
mortgage be the lesser of
• the amount required to compensate for any damage or loss on a replacement cost
basis (or UPB if replacement cost coverage is not available), or
• the maximum insurance available from the NFIP.27
When UPB is the selected option, the minimum amount of flood insurance must be at least 80%
of the RCV of the structure. However, if the UPB is less than 80% of the RCV, the required
insurance coverage amount must still be at least 80% of the structure (market) value.
Because the NFIP flood insurance dwelling policy pays 100% of a loss on the basis of
replacement cost only when the amount of insurance purchased is at least 80% of the replacement
cost of the building, a lender must obtain coverage for at least 80% of replacement cost (the
minimum amount required) in order to meet Fannie Mae’s standards. This means replacement
cost coverage is considered not available when the property is insured for less than 80% of its
replacement cost. Coverage in a lesser amount would not meet the standard for replacement cost
because it would be subject to the (20%) co-insurance payment.
In light of Fannie Mae’s flood insurance standards, lenders typically will insist on flood insurance
amounts of at least 80% of the replacement cost of the insurable value of the property—up to the
maximum available under the NFIP—rather than the outstanding loan balance amount. Again, if
the UPB is less than 80% of the replacement cost, the required insurance coverage amount must
be at least 80% of the structure value. This is based on Fannie Mae’s interpretation of FEMA’s
guidance. It is important to point out that the authority of FEMA remains limited to its statutory
responsibility of administering the NFIP. In other words, FEMA does not have direct
responsibility for enforcement of the mandatory flood insurance purchase requirements. This is
the responsibility of the banks and other financial institutions.
As an illustration of Fannie Mae’s interpretation of FEMA’s regulatory standard, a borrower with
a UPB of $100,000 on property with a replacement value of $300,000 would be required to
purchase minimum flood insurance coverage equal to $240,000 (80% of $300,000), and not the
outstanding loan value of $100,000. Thus, the borrower could find himself/herself paying for
coverage that is substantially greater than the outstanding loan balance.

Appendix A. Evolution of Federal Financial
Regulatory Agency Regulation
Title V of the Riegle Community Development and Regulatory Improvement Act of 1994, which
is also know as the National Flood Insurance Reform Act of 199428 (Reform Act), broadened the
definition of “federal regulated lending institution” to include the Farm Credit Administration
(FCA), thereby increasing the number of lending institutions subject to the mandatory flood
insurance purchase requirement. The 1994 Reform Act applied flood insurance requirements
directly to loans purchased by the Federal National Mortgage Association (Fannie Mae) and the
Federal Home Loan Mortgage Corporation (Freddie Mac) and to agencies that provide
government insurance or guarantees such as the Small Business Administration (SBA), Federal
Housing Administration (FHA) and the Veterans Administration (VA).
Each federal regulatory agency was given the right to issue its own regulations to implement the
mandatory flood insurance purchase requirement provisions in the 1973 and 1994 Acts. The six
federal financial regulatory agencies exercise their rights by issuing substantially similar joint
final regulations on August 29, 1996 (the Regulations)29 and have coordinated and consulted with
the Federal Financial Institutions Examination Council (FFIEC).30 The Regulations establish the
mandatory purchase requirements in the following way:
A bank shall not make, increase, extend, or renew any designated loan unless the building or
mobile home and any personal property securing the loan is covered by flood insurance for
the term of the loan. The amount of insurance must be at least equal to the lesser of the
outstanding principal balance of the designated loan or the maximum limit of coverage for
the particular type of property under the Act. Flood insurance coverage is limited to the
overall value of the property securing the designated loan minus the value of the land on
which it is situated.31
Fannie Mae and Freddie Mac also established procedures to implement the NFIP’s mandatory
flood insurance purchase requirement.32
Despite the guidance provided by the Regulations, lenders still struggled with the lack of
certainty and uniformity with the mandatory flood insurance provisions of the 1994 Reform Act.
In 1997, the federal financial regulatory agencies responded to these concerns with the release of
28 P.L. 103-325, 108 Stat. 2255.

Mandatory Flood Insurance Purchase in Remapped Residual Risk Areas Behind Levees
the Loans in Areas Having Special Flood Hazard: Interagency Questions and Answers Regarding
Flood Insurance;33 however, considerable ambiguity and confusion remained.
On May 25, 2006, Fannie Mae revised its existing mandatory flood insurance coverage
requirements applicable to single and multi-family properties to the lowest of (1) the amount
required to compensate for any damage or loss on a replacement cost basis (or unpaid principle
balance if replacement cost coverage is not available); or (2) the maximum insurance available
from the NFIP. This requirement is substantially similar to requirements issued by the NFIP;
however, Fannie Mae tends to have stricter requirements for lenders that exceed the NFIP’s three
options. The Fannie Mae regulation requires that when the unpaid principal balance (UPB) is the
selected option, flood insurance purchase amount must be at least 80% of the structure
replacement cost. If the UPB is less than 80% of the replacement cost, the required insurance
coverage amount must be at least 80% of the structure value.34
On March 21, 2008, in an effort to promote the consistent interpretation, application, and
examination of bank regulatory obligations arising from implementation of the 1994 reform, the
federal lending regulatory agencies, under the auspices of the FFIEC, proposed major revisions to
the interagency questions and answers document.35 The proposed changes were in areas such as
second lien mortgages, construction loans and condominiums, the implementation of civil money
penalties, loan syndications/participation, the imposition of new guidelines for handling
discrepancies between flood zone descriptions in the flood determination form and the flood
insurance policy, and a re-organization to make the guidance easier to use. On July 21, 2009, the
agencies issued a modified version of the Flood Q&A after considering the comments received.
Effective September 21, 2009, the agencies’ modified Flood Q&A supersede the 1997
Interagency Questions and Answers and supplement other guidance or interpretations issued by
the agencies and FEMA.36
The Federal Housing Finance Agency (FHFA) was created as a new, unified regulator for Fannie
Mae, Freddie Mac, and the Federal Home Loan Banks under the Housing and Economic
Recovery Act of 2008 (HERA).37 On October 10, 2008, the FHFA requested public comments on
the issuance of a proposed flood insurance regulation to codify the authority and responsibility of
FHFA to oversee and enforce the statutory requirements affecting the operations of Fannie Mae
and Freddie Mac.38 Section 1161(e) of HERA amended section 102(f)(3)(A) of the Flood Disaster
Protection Act of 1973 by replacing the Office of Federal Housing Enterprise Oversight
(OFHEO) in the Department of Housing and Urban Development (HUD) with FHFA as the
