Arizona: $400 million casino ready to roll Tom Scanlon, Glendale Star · February 13, 2020 at 4:42 pm It was 2 p.m. last Thursday, just a regular day of the week. Desert Diamond West Valley Casino’s parking lot was flush, so to speak. Cars were circling and circling, looking for a parking space like the mall during Christmas time. Clearly, the West Valley is ready for the Tohono O’odham Nation’s massive expansion. A temporary casino has been here at 91st and Northern avenues, bordered by Glendale and Peoria. Next to it, construction crews are working intensely on the final phases of the permanent casino. Starting at 8 p.m. Wednesday, Feb. 19, the new casino will be ready to roll.
