In 2000, Maricopa County voters passed a ballot initiative by a margin of 51% to 49%, providing funding for a new Cardinals stadium (as well as for improvements to Major League Baseball spring training facilities in the greater Phoenix region; and youth recreation). After some legal obstacles, the Cardinals began construction of their new facility in April 2003, in Glendale, one of the western suburbs of Phoenix. State Farm Stadium features a retractable roof and a slide-out grass surface, which is good for the hot desert weather; the new stadium has a state-of-the-art air conditioning system and high-back seats. The Cardinals' executive offices and training facility remained in Tempe, in a complex (built in 1990) about south of Sun Devil Stadium.
