The City of Hillsboro (ballpark owner) has contracted a design-builder, Mortenson, along with SRG Partnership and Populous to expand Ron Tonkin Field to meet the new Major League Baseball (MLB) standards for a High-A Long Season ballpark. Mortenson and Populous have designed and built a long list of noteworthy sports and stadium projects, including Climate Pledge Arena in Seattle and Target Field for the Minnesota Twins. The project begins later this year.
