"The Arizona Diamondbacks are looking at four new spring training sites around metro Phoenix, including one owned by the Gila River Indian Community, and could move from Tucson by 2011... Hall said the Diamondbacks would like to decide shortly after the first of the year on a future spring training site. He said the timing was necessary because it takes 18 months to two years to build a new facility."

The article mentions a possible two-team facility south of Phoenix, on land owned by the Gila River Indian Community. It appears other tribes are also on the list for the facility, which will be privately financed. A new facility in Tucson for the Diamondbacks is also mentioned as a candidate.
