Yes ma'am. Most have to be flat and bronze. Depending on the section your plot is in. I'd have to pull my paperwork to give you more details
There are no upright headstones. As Eric said depending on the area you are buried is how they determine the material. My mother is buried there and I bought her stone. The cemetery will tell you. Burials in the front has to be bronze. My mom is buried in the back and they told me those didn't have to be bronze that I could choose. I chose granite from caskets and more.
Please give more specifics and thank you for responding
