I am the grantee. I was granted an "Exclusive" Easement across corner of neighbor's Lot 9 in 1994. Can new present owners of Lot 9 give their permission for someone else to use that same portion of lot. Namely, there is an unopened city road that the portion of easement is adjacent to, and I use that unopened ROW as driveway (and have since 1965). The only access to the Unopened ROW is over my Exclusive Easement, as the portion of Unopened
ROW that abutts the open city ROW is landscaped and steep. In order for any one else to use the Unopened ROW, they would have to improve the entire ROW and get a trail permit and "open" it.
The city asked the owners of Lot 9 if they could access their ROW by traversing across my easement. I don't think the owners have that right to grant access across my easement to someone else, do they?
