REPORT
[To accompany H.R. 900]
The Committee on Natural Resources, to whom was referred the
bill (H.R. 900) to direct the Director of the United States Geological
Survey to establish a program to map zones that are at greater
risk of sinkhole formation, and for other purposes, having consid-
ered the same, reports favorably thereon with an amendment and

SECTION 1. SHORT TITLE.
This Act may be cited as the Sinkhole Mapping Act of 2025.
SEC. 2. SINKHOLE HAZARD IDENTIFICATION.
(a) IN GENERAL.-Subject to the availability of appropriations made in advance for
such purpose, the Director of the United States Geological Survey shall establish a
program to-
(1) study the short-term and long-term mechanisms that cause sinkholes, in-
cluding extreme storm events, prolonged droughts causing shifts in water man-
agement practices, aquifer depletion, and other major changes in water use; and
(2) develop maps that depict zones that are at greater risk of sinkhole forma-
tion.
(b) USE OF CERTAIN DATA.-In developing maps under subsection (a)(2), the Direc-
tor of the United States Geological Survey shall utilize 3D elevation data (as that
term is defined in section 2 of the National Landslide Preparedness Act (43 U.S.C.
3101)) collected pursuant to section 5 of that Act (43 U.S.C. 3104).
(c) REVIEW OF MAPS.-Once during each 5-year period, or more often as the Direc-
tor of the United States Geological Survey determines is necessary, the Director
shall assess the need to revise and update the maps developed under this section.

and maintain a public website that displays the maps developed under this section
and other relevant information critical for use by community planners and emer-
gency managers.
