Then, she is not allowed to park in the easement - an easement holder is NOT the owner of the property and they can only it as per the easement or servitude grant.
An easement holder may not hinder another, may not erect nor place an obstacle on a right of way
, nor render its exercise more difficult or otherwise deprive its beneficiary from using the right.
One does not have to navigate within a easement - they are to park off the easement.
Your options are to file suit and get an injunction against her from continuing to hinder others use of the easement.
Moreover, most judge's give the prevailing party in easement cases their attorney's fees and court costs if they have given notice the encroaching party to stop but they continue to do such.
What I would do is send the wrongful easement user a letter stating that they are preventing the other easement holders use of the easement in violation of the law. That if they continue to do such you will have to pursue your legal remedies which include filing suit and pursuing and injuction against them for their wrongful conduct.
The law is very clear - they do not have the right to park in the easement nor make it more difficult for the other easement holders to use.
