Easement for Ingress, Egress and Regress

[FOSTER]

A PLS or RCE submits a Record of Survey of a parcel that was created by deed and within the deed Parcel 1 (PIQ) and Parcel 2 (Private Access Road Easement) are explained but only Parcel 1 is depicted on the RS. No lines are delineated to show Parcel 2 nor is there a Surveyor's or Engineer's Statement explaining the access easement. The map appears to shown the P.I.Q. to be land locked. How does "Joe Public" in reading this map know how to get to the property? Property to the north are also deeds and depict similar easement rights to access their property through the deeded property in question. If the P.L.S. Act [say in 8764 (d) (g)] does not adequately address the question at hand, then when does one show or explain an easement for Ingress, Egress and Regress purposes on a Record of Survey? What are the C.L.S.A. professional opinions when it is appropriate or prudent to show an easement on a Record of Survey?
