So, my private road, each property has a 33 fr access and utility easement centered on the road, so not Right of Way, but a blanket easement pretty much for everyone and everything. Not the same as the county or state owning "in fee". With that, they have no responsibility to do anything, and they won't.
My understanding, per out LDC (Land Development Code) these type of easements are not allowed to serve more than 4 properties on new subdivisions.
County could, if they wanted, easily just take the 66 ft, but they would than be responsible
A one time, there was a POA that was responsible for maintaining, but it sunsetted, and was dissolved.
