Law

The United States Geological Survey would create a new program to study what causes sinkholes. They will look at how extreme weather, like heavy rain or long droughts, and changes in how we use water can make the ground collapse.
Experts will use high-tech 3D data to make maps that show which areas are most likely to have sinkholes. These maps will be updated at least every five years to keep up with changes in the environment and water levels.
The government will launch a public website where anyone can look at these maps. This is designed to help city leaders and emergency teams plan safer building projects and prepare for potential disasters before they happen.
