 To direct the Director of the United States Geological Survey to

 Be it enacted by the Senate and House of Representatives of the

 This Act may be cited as the ``Sinkhole Mapping Act of 2025''.

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, including extreme storm events, prolonged 
 droughts causing shifts in water management practices, aquifer 
 depletion, and other major changes in water use; and

    (2) develop maps that depict zones that are at greater risk 
 of sinkhole formation.

    (b) Use of Certain Data.--In developing maps under subsection

    (a)

    (2) , the Director of the United States Geological Survey shall 
utilize 3D elevation data (as that term is defined in

section 5 of that Act (43 U.S.C. 3104).

necessary, the Director shall assess the need to revise and update the 
maps developed under this section.
            (d) Website.--The Director of the United States Geological Survey 
shall establish and maintain a public website that displays the maps 
developed under this section and other relevant information critical 
for use by community planners and emergency managers.
