I do believe it's a jurisdiction thing. Some states may require an easement be monumented, they have gotten close to that here. If there is an existing road I would centerline it and basically call it the monument buy stating, the centerline of an existing road being more particularly described,,,,,,
The road is the monument.
The actual driveway is sufficient monumentation. If there are utilities not congruent with the driveway they may need to be monumented or separately described.. Typically calls from existing monumented corners to starting and ending points of described easements is sufficient.
The easement exists by acquiescence and needs only to be generously described.

A lot of times utilities are also located in or along an access driveway, phone, gas, buried power drops. When they're all on the clients property an easement isn't an issue but if the land they're crossing is sold to a third party, make sure besides ingress/egress, it also covers utilities. Heard a horror story or two when they were not included and third party buyer turned out to be a jerk. Just food for thought.
NC requires easements to be monumented where they intersect a property line. If the easement runs parallel to the boundary it is considered to be sufficiently monumented.
This wasn’t always the case. Therefore there are lots of unmonumented easements out there.
I like to tie access easements to nearby boundary monuments at their POB and POT then set a pair of irons near the middle. Setting monuments at easement corners that are in close proximity to lot corners can cause more problems than it prevents.
