Carsten

Defendants City of Del Mar and its council members Elliot Parks, Rod Franklin, Jan McMillan, Gay Hugo-Martinez, and Jacqueline Winterer (together Del Mar) appeal an order granting plaintiff Alfred Carsten’s request for a preliminary injunction barring Del Mar from commencing any work under its Neighborhood Traffic Control Plan (the Plan) involving the construction of “traffic medians, islands, or other barriers” on city streets. Del Mar contends the court erred in applying an incorrect legal standard to the facts before it and in granting a preliminary injunction without finding it was likely Carsten would prevail on the lawsuit’s merits. Del Mar also attacks as without substantial evidentiary support the court’s finding the relative hardships to the parties warranted injunctive relief. We reverse the order granting the preliminary injunction.
