We are proud to have added two farms to this list, in addition to the 1,846 acres we have already helped to preserve to date!

As Ohio continues to attract data centers, housing developments and other large-scale projects, a state program is working to help preserve agricultural land across the Buckeye State. https://www.nbc4i.com/news/local-news/central-ohio-news/ohio-farmland-preservation-program/?utm_medium=social&utm_source=facebook_NBC4

Sinkholes can occur here in Delaware County, due to our karst landforms on the western side of the Olentangy River where you find thick limestones and dolostones. The good news is that our sinkholes only widen or deepen by a couple of inches per year at most.

Check out this diagram and links from Ohio Geological Survey to learn more about why this happens. They even have a sinkhole reporting form and interactive karst map!

If you have a question about a sinkhole, tile collapse, or drainage issue on your property, reach out to us!

As we wrap up , it’s a great chance to continue learning about Ohio’s caves and other karst features.

We invite you to dig deep and check out our great educational resources on karst in Ohio:
