Notwithstanding any other provisions of this chapter, the county commissioners of each county may move graves or cremate the bodies in any graves which are located in the county and maintained by the county when the gravesites are in imminent danger of destruction by natural elements. The county commissioners shall, to the extent possible, give personal notice to a relative of a deceased person whose grave is to be moved or whose body is to be cremated if the identity of that person and the identity of the relative are known. The county commissioners shall provide at least thirty days’ prior notice in a legal newspaper of the county of the commissioners’ intended action to be taken pursuant to this section.
