Mission & History

The Washington State Major League Baseball Stadium Public Facilities District (Ballpark PFD or PFD) is a municipal corporation that owns T-Mobile Park in Seattle and oversees its operation. The PFD ensures that the interests of the people of the state, the users of the ballpark, and the people who live and work in the neighborhoods surrounding the ballpark are met with balance and fairness.

In 1995 the Washington State Legislature authorized King County to create the Ballpark PFD, and the King County Council formally established the PFD by ordinance that fall.

The PFD’s mission is "to maintain and enhance our iconic baseball park in order to promote the success of Major League Baseball in the State of Washington, enhance fan enjoyment, and contribute to an economically successful, safe, desirable, innovative, and walkable stadium neighborhood." The PFD has interests beyond the ballpark’s walls, working to leverage its value to encourage positive outcomes in transportation, zoning and development, and livability issues in surrounding neighborhoods.

The PFD and the Seattle Mariners work closely together toward our common goal of ensuring that T-Mobile Park remains among the top-ten ballparks in the country and is operated as a first-class facility for baseball and other events.  We also work to ensure that the ballpark serves as a good neighbor in the community.
