For me yes it's unnecessary but I'm not mainstream in that I enjoy walking and riding my bike whenever possible and the bus occasionally. I've got neighbors who drive their cars a single block to go to work and I'm sure they're more typical than I am when it comes to transportation. 
It's my understanding that the LTD move from the existing location is primarily due to the work that ODOT is going to do on the adjacent interchange. Probably more to it than that but at least there's some validity to the move.

I do wish the city would take some of that park money and put in some hills in the Santa Clara area, it would save me a lot of trips south.
