Mesa Proving Grounds was part of the 5,000-acre General Motors Desert Proving Grounds when it was purchased by DMB Mesa Proving Grounds LLC, an affiliate of Arizona’s DMB Associates, Inc. (DMB), in late 2006. Located adjacent to Phoenix-Mesa Gateway Airport and ASU Polytechnic campus, the 3,200-acre Mesa Proving Grounds is the largest remaining parcel of contiguous land within the Mesa planning area and is of tremendous importance to the future of Mesa and the entire region.

As General Motors is winding down its hot weather vehicle testing operations at the proving grounds, DMB is beginning an in-depth planning process for the future of the property.

DMB has embarked upon a listening and learning process with City leaders, residents and businesses to explore potential long-term uses for the site. This process will assist DMB in developing an appropriate land plan for the property. It is DMB’s vision that Mesa Proving Grounds will be a catalyst for the type of development being sought by regional leaders for this important and strategically situated part of the Greater Phoenix metropolitan area.

The Mesa Proving Grounds Web site has been created to serve as the primary information source for the community during the planning process for the property. We encourage you to sign up to receive regular updates and stay informed, and to visit the Web site frequently for new information and progress reports.
