Dear Colleague:

Please join me in becoming an original co-sponsor of
the Sinkhole Mapping Act of 2018, a bill that would improve our understanding of sinkholes.

Sinkholes are caused by erosion, and they appear suddenly and have devastating consequences. The dangers of sinkholes are real and they occur in every state
and territory. The cost of sinkhole damage to property over the last 15 years cost, on average, at least $300 million per year. While rare, sinkholes can be deadly. Around 11pm on the evening of February 28, 2013, Jeff Bush, a man from central Florida, was
asleep in his bedroom when a large sinkhole opened directly under the house, swallowing him and his entire bedroom.

The United States Geological Survey (USGS) currently studies sinkholes, and the Sinkhole Mapping Act of 2018 would build on existing research activities
that are making advances in understanding the geologic and hydrologic controls in sinkhole-prone landscapes, known as karsts. To better inform and support rapid response to sinkhole formation and effective mitigation measures, the bill would direct the USGS
to focus on the short- and long-term mechanisms that trigger sinkholes, including extreme storm evens, prolonged droughts leading to shifts in water management practices, as well as ongoing aquafer depletion, and other major changes in water use.  The bill
would also direct the Director of the USGS to establish and maintain a public website that displays maps that depict zones that are at greater risk of sinkhole formation and other relevant information critical for use by community planners and emergency managers.

I urge you to become an original co-sponsor of the Sinkhole Mapping Act off 2018. Let’s give community planners and first responders access to information
on where sinkholes are likely to form. If you have any questions, or would like to sign onto the Act, please contact Martin Rivera at
