The LA times has the story. The Angels want to stay in Anaheim. They want to refurbish Angel Stadium instead of Arte building a whole new stadium (somewhere else, maybe even in L.A.)
The Anaheim city council wants this to be but the mayor of Anaheim, Tom Tait, doesn't want this, he wants the Angels to move and is asking for a study to prove that the plot of land where the stadium and parking lots are at is worth more to the city without the Angels there then with them there.
What is really going on is that Arte wants to be given the land in exchange for the city of Anaheim not having to pay for stadium maintenance. Right now the city owns the land and pays for stadium maintenance. There is much work to be done on that stadium, it opened in 1966.
If we win the World Series in the next few years watch Arte bolt. He has made rash, bold moves before. The mayor is not the same guy who fought Arte over the naming of the team but he is being stubborn and basically is anti-Arte. So what if the city could make more money from the parcel of land with someone else there - the point is the Angels leaving Anaheim affects the city negatively as a quality of life issue.
