                          Purpose of the Bill

    The purpose of H.R. 5787 is to amend the Coastal Barrier 
Resources Act to give effect to more accurate maps of units of 
the John H. Chafee Coastal Barrier Resources System that were 
produced by digital mapping of such units.

                  Background and Need for Legislation

    In 1981, due to the high risk that coastal developments 
carry, Congress directed the Secretary of the Interior to draw 
maps designating undeveloped coastal barriers unsuitable for 
new federal development subsidies, including federal flood 
insurance.\1\ In 1982 Congress enacted the Coastal Barrier 
Resources Act (CBRA, 16 U.S.C. 3501 et seq.). CBRA established 
the Coastal Barrier Resources System (CBRS) administered by the 
U.S. Fish and Wildlife Service (USFWS).\2\ CBRS units are 
depicted on maps on file with the USFWS. CBRA prohibits the use 
of federal dollars to subsidize new development on CBRS units, 
except for limited exceptions such as maintenance of federal 
navigation channels and military readiness.\3\ The Coastal 
Barrier Improvement Act of 1990 added ``Otherwise Protected 
Areas'' (OPAs) to the CBRS.\4\ While CBRS units carry the full 
funding prohibitions of CBRA, structures within OPAs\5\ are 
prohibited only from receiving flood insurance under the 
National Flood Insurance Program.\6\

    \4\Public Law 101-591, Coastal Barrier Improvement Act of 1990.
    \5\As defined by Public Law 101-591, otherwise protected areas may 
be comprised of ``undeveloped coastal barrier[s] within the boundaries 
of an area established under Federal, State, or local law, or held by a 
qualified organization, primarily for wildlife refuge, sanctuary, 
recreational, or natural resource conservation purposes''.

---------------------------------------------------------------------------
    CBRA was intended to impact only coastal areas that were 
undeveloped at the time of enactment so that existing coastal 
communities would not be adversely affected. Further, CBRA did 
not apply to the approximately 47% of coastal areas that were 
undeveloped but already protected by existing law.\7\ At the 
time of enactment, approximately 13% of coastal areas along the 
Atlantic and Gulf Coasts were undeveloped and unprotected,\8\ 
and the original CBRS included approximately 590,000 acres.\9\ 
In 2002, USFWS published a report commemorating the 20th 
anniversary of CBRA. This report conservatively estimated that 
the program was on track to save taxpayers $1.3 billion through 
2010 and that an additional $200 million in federal disaster 
relief could be saved by 2050.\10\ Furthermore, a 2007 
Government Accounting Office report found that approximately 
84% of CBRS units remained undeveloped, and only 3% of units 
have experienced significant development since the passage of 
CBRA.\11\ Currently the CBRS consists of 3.3 million acres in 
23 states and territories along the Atlantic, Gulf of Mexico, 
Great Lakes, U.S. Virgin Islands and Puerto Rico coasts.\12\

    Congress has reauthorized CBRA three times.\13\ The most 
recent reauthorization, the Coastal Barrier Resources 
Reauthorization Act of 2005, directed USFWS to finalize and 
submit to Congress a report on the digitization of CBRA 
maps.\14\ USFWS transmitted the final report in November 2016 
which included final recommended boundaries for CBRS units and 
OPAs.\15\ The recommendations in the report impact maps in 
Delaware, North Carolina, South Carolina, Florida and 
Louisiana. In general, under current law, Congress must codify 
significant changes to CBRA maps for any new maps to take 
effect.\16\

    In response to the 2016 report, several members of 
Congress, including Representatives Neal P. Dunn (R-FL), Lisa 
Blunt Rochester (D-DE) and Thomas Rooney (R-FL), introduced 
bills to codify the revised, digital maps that impact their 
districts. The Subcommittee on Water, Power and Oceans held a 
legislative hearing on two of these bills on February 27, 2018: 
H.R. 2947 (Dunn) and H.R. 4880 (Blunt Rochester). Representing 
USFWS, Mr. Gary Frazer testified in support of both two 
bills.\17\ After this hearing, the bill sponsors worked 
together to codify these maps in a more comprehensive fashion.
---------------------------------------------------------------------------
    \17\Legislative Hearing on H.R. 2947 and H.R. 4880: Hearing before 
the Natural Resources Committee Subcommittee on Water, Power and 
Oceans, House of Representatives, 115th Cong., 2 (2018) (Testimony of 
Gary Frazer), at 1.
---------------------------------------------------------------------------
    H.R. 5787, codifies 32 CBRS maps that were revised and 
digitized as part of the Digital Mapping Pilot Project by 
USFWS. Further, the bill implements the USFWS recommendations 
for the St. Andrew's Complex P31 and P31P CBRS units, for a 
total of 35 new maps.
    As the Committee considered this legislation, several 
questions arose related to the efficacy and legal integrity of 
digital maps in general. Digital documents lack the permanence 
and constancy of hard copy documents, and there are few 
examples, if any, throughout the federal government where 
digital documents carry the full force of law and are 
authorized for official use. Accordingly, section 3 of H.R. 
5787 requires the USFWS Director to keep a printed, hard copy 
of each digital map authorized by law and make final 
determinations as to whether a location is inside or outside 
the CBRS based solely on this printed version.
    USFWS also developed advanced mapping systems, including 
GIS technology, to accompany these digital maps, increasing 
their accuracy and aiding in interpretation. These mapping 
systems capitalize on the benefits that digital maps can 
provide, and their appropriate use can improve the CBRA 
program. However, as with digital maps in general, there are 
several concerns that arose with respect to mapping integrity 
as this legislation was considered by the Committee. These maps 
and the agency interpretation thereof can have significant 
impacts on people's lives. Under 16 U.S.C. 3504, when a certain 
area of land is determined to be within the boundaries of the 
CBRS, the residents of that area lose federally-subsidized 
flood insurance under the National Flood Insurance Program, the 
area may become ineligible for certain types of federally-
supported dredging projects that are important for navigation 
and human safety, and other federal benefits like sewage 
treatment system grants, can be affected. Before Congress can 
authorize the use of these new mapping systems to interpret the 
boundaries of CBRS units and OPAs, USFWS must certify and 
document that these maps and GIS systems are developed and 
maintained in a manner that will preserve the integrity of the 
program and the rule of law.
    The Committee expects that when this legislation reaches 
the House floor, it will include language directing USFWS to 
submit a report to Congress related to the successes and 
challenges of the transition from paper maps to digital maps. 
It is the Committee's expectation that in this report, as part 
of a larger analysis on the subject, USFWS will address, with a 
high degree of specificity, the following questions:
          (1) How accurate are the mapper data?
          (2) What is the source of the mapper data?
          (3) Are these data digitized or born digital?
          (4) For digitized data, how were the data ingested 
        into the database?
          (5) For digital data, how were the data created?
          (6) Are those data sources consistent at a national 
        level? If not, how do they vary in detail, and what are 
        the implications for implementing a common dispute 
        resolution process when parties differ over boundaries?
          (7) Is there a national mapping data standard or many 
        local standards based on available data?
          (8) What written publicly available guidance, rule, 
        or regulation governing boundary dispute resolution 
        processes have been released?
          (9) What are USFWS's plans to maintain mapper data, 
        hardware, and software?
          (10) What migration plans are in place to ensure that 
        consistent data and renderings will be available over 
        time as operating systems, applications, and user 
        interfaces evolve?
          (11) How do these plans comply with existing 
        statutory requirements or those proposed under H.R. 
        5787?
    Answers to these questions and the entirety of this report 
should determine the degree to which, if at all, it is 
appropriate for USFWS to utilize the GIS and other advanced 
digital mapping systems in the agency's interpretation of these 
new digital maps.

bill from the Director of the Congressional Budget Office:

                                     U.S. Congress,
                               Congressional Budget Office,
                                      Washington, DC, July 9, 2018.
Hon. Rob Bishop,
Chairman, Committee on Natural Resources,
House of Representatives, Washington, DC.
    Dear Mr. Chairman: The Congressional Budget Office has 
prepared the enclosed cost estimate for H.R. 5787, the 
Strengthening Coastal Communities Act of 2018.
    If you wish further details on this estimate, we will be 
pleased to provide them. The CBO staff contact is Jeff LaFave.
            Sincerely,
                                             Mark P. Hadley
                                        (For Keith Hall, Director).
    Enclosure.

H.R. 5787--Strengthening Coastal Communities Act of 2018

    H.R. 5787 would update the maps for various units of the 
Coastal Barrier Resources System (CBRS). Using information 
provided by the U.S. Fish and Wildlife Service, CBO estimates 
that updating the maps would have no significant effect on 
spending subject to appropriation.
    The bill would revise the CBRS maps for 35 units within the 
system and would add, on net, about 18,000 acres to the system 
(increasing the size of the CBRS by 0.5 percent). CBO expects 
that the new maps would exclude lands containing about 500 
structures, which would enable owners of those structures to 
purchase flood insurance from the federal government. CBO 
estimates that enacting H.R. 5787 could increase premium 
collections of the National Flood Insurance Fund by less than 
$1 million annually. On an expected-value basis those 
collections, which are recorded as offsets to direct spending, 
would be roughly offset by new mandatory spending for 
underwriting, administrative expenses, and new flood insurance 
claims over the 2019-2028 period.
    Because enacting the bill could affect direct spending, 
pay-as-you-go procedures apply. However, CBO estimates that any 
net change in direct spending would be negligible over the 
2019-2028 period. Enacting the bill would not affect revenues.
    CBO estimates that enacting H.R. 5787 would not 
significantly increase net direct spending or on-budget 
deficits in any of the four consecutive 10-year periods 
beginning in 2029.
    H.R. 5787 contains no intergovernmental or private-sector 
mandates as defined in the Unfunded Mandates Reform Act.
    The CBO staff contact for this estimate is Jeff LaFave. The 
estimate was reviewed by H. Samuel Papenfuss, Deputy Assistant 
Director for Budget Analysis.
    2. General Performance Goals and Objectives. As required by 
clause 3(c)(4) of rule XIII, the general performance goal or 
objective of this bill is to amend the Coastal Barrier 
Resources Act to give effect to more accurate maps of units of 
the John H. Chafee Coastal Barrier Resources System that were 
produced by digital mapping of such units.

  (b) System Maps.--
          (1) In general.--The Secretary shall keep the maps 
        referred to in subsection (a) on file and available for 
        public inspection in the Office of the Director of the

are necessary solely to reflect changes that have occurred in 
the size or location of any System unit as a result of natural 
forces.
  (d) Additions to System.--The Secretary may add a parcel of 
real property to the System, if--
          (1) the owner of the parcel requests, in writing, 
        that the Secretary add the parcel to the System; and
          (2) the parcel is an undeveloped coastal barrier.

        System or in determining whether, at the time of the 
        inclusion of a System unit within the System, a coastal 
        barrier is undeveloped, the Secretary shall consider 
        whether within the area--
                  (A) the density of development is less than 1 
                structure per 5 acres of land above mean high 
                tide; and
                  (B) there is existing infrastructure
