We live in Herald Calif. out in the county on acreage. We have an easement (20 ft) that crosses the three adjoining properties to the east of us. This easement services a total of five property owners, plus the first owner. The owner of the eastern most property (the first property that we cross) is having a problem with the middle landowner over his speeding through her part of the easement. There is no mutual maintenance agreement associated with these easements.
The first landowner is under the impression that she controls (in total?) the rights to her portion of the easement. To include posting a speed limit and not permitting me to fill the numerous potholes.
1. Does she have any right to post and enforce a "reasonable" speed limit?
2. How could she best enforce any legally posted speed limit?
3. Do I have (or any of the other legal users of the easement) any rights
to maintain the easement?
