 establish a program to map zones that are at greater risk of sinkhole

SECTION 1. SHORT TITLE.

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

SEC. 2. SINKHOLE HAZARD IDENTIFICATION.

    (a) In General.--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 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 Director 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.
    (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.
