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 

4 

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’’. 6 42 U.S.C. 4028(b), National Flood Insurance Act of 1968 as amended by Public Law 101–

Pilot Project, November 29, 2016. 16 16 U.S.C. 3503(a)(3). 

OPAs 5 are prohibited only from receiving flood insurance under 

the National Flood Insurance Program.6

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 FrazVerDate Sep 11 2014 04:13 Oct 31, 2018 Jkt 089006 PO 00000 Frm 00004 Fmt 6659 Sfmt 6602 E:\HR\OC\HR997.XXX HR997

17Legislative 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. 

er 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. 

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 federallysubsidized flood insurance under the National Flood Insurance Program, the area may become ineligible for certain types of federallysupported 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 

(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. 

SECTION-BY-SECTION ANALYSIS

COMPLIANCE WITH HOUSE RULE XIII AND CONGRESSIONAL BUDGET

ACT

1. Cost of Legislation and the Congressional Budget Act. With respect to the requirements of clause 3(c)(2) and (3) of rule XIII of 

the Rules of the House of Representatives and sections 308(a) and 

402 of the Congressional Budget Act of 1974, the Committee has 

received the following estimate for the 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-asyou-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. 

EARMARK STATEMENT

This bill does not contain any Congressional earmarks, limited 

tax benefits, or limited tariff benefits as defined under clause 9(e), 

9(f), and 9(g) of rule XXI of the Rules of the House of Representatives. 

COMPLIANCE WITH PUBLIC LAW 104–4 

This bill contains no unfunded mandates. 

COMPLIANCE WITH H. RES. 5 

Directed Rule Making. This bill does not contain any directed 

rule makings. 

Duplication of Existing Programs. This bill does not establish or 

reauthorize a program of the federal government known to be duplicative of another program. Such program was not included in 

any report from the Government Accountability Office to Congress 

pursuant to section 21 of Public Law 111–139 or identified in the 

most recent Catalog of Federal Domestic Assistance published pursuant to the Federal Program Information Act (Public Law 95–220, 

as amended by Public Law 98–169) as relating to other programs. 

PREEMPTION OF STATE, LOCAL OR TRIBAL LAW

This bill is not intended to preempt any State, local or tribal law. 

CHANGES IN EXISTING LAW MADE BY THE BILL, AS REPORTED

In compliance with clause 3(e) of rule XIII of the Rules of the 

House of Representatives, changes in existing law made by the bill, 

as reported, are shown as follows (new matter is printed in italic 

and existing law in which no change is proposed is shown in

16, 1990, that specifically replaces such a map or authorizes 

the modification, revision, or correction. 

(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 United States Fish and 

Wildlife Service, and in such other offices of that service as the 

Director considers appropriate. 

(2) DIGITAL MAPS.— 

(A) AVAILABILITY.—The Secretary shall make available to 

the public on the Internet web site of the United States Fish 

and Wildlife Service digital versions of the maps included 

in the set of maps referred to in subsection (a). 

(B) EFFECT.—Any determination as to whether a location 

is inside or outside the System shall be made without regard to the digital maps available under this paragraph, 

except that this subparagraph does not apply with respect 

to any printed version of such a digital map if the printed 

version is included in the maps referred to in subsection 

(a). 

(c) BOUNDARY REVIEW AND MODIFICATION.—At least once every 

5 years, the Secretary shall review the maps referred to in subsection (a) and shall make, in consultation with the appropriate 

State, local, and Federal officials, such minor and technical modifications to the boundaries of System units as 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. 

(e) ADDITION OF EXCESS FEDERAL PROPERTY.— (1) CONSULTATION AND DETERMINATION.—Prior to transfer or 

disposal of excess property under the Federal Property and Administrative Services Act of 1949 (40 U.S.C. 471 et seq.) that 

may be an undeveloped coastal barrier, the Administrator of 

General Services shall consult with and obtain from the Secretary a determination as to whether and what portion of the 

property constitutes an undeveloped coastal barrier. Not later 

than 180 days after the initiation of such consultation, the Secretary shall make and publish notice of such determination.
