PORTLAND, Ore. — Portland Diamond Project formally rescinded its offer to purchase the site of the Portland Public Schools headquarters near the Moda Center as a potential location for a baseball stadium in Portland.

The group, which is trying to bring Major League Baseball to Portland, said it plans to make an announcement about other ballpark site options in a few weeks. The group said the site will be within Portland's city limits.

In April, Portland Diamond Project submitted offers for the PPS site as well as ESCO's headquarters in Northwest Portland. The ESCO site was sold to a group of Portland developers for $33 million.

In July, PDP managing partner Mike Barrett said the group would announce a site for a ballpark in four to six weeks, saying the group was "down to a few favorites."

In addition to the PPS and ESCO sites, the following potential stadium locations in Portland have been publicly reported.

  • Terminal 2, owned by the Port of Portland, along the Willamette River. Melanie Mesaros, a spokesperson with Port of Portland, spoke with KGW on Wednesday. She confirmed Terminal 2 is one of the sites under consideration by PDP, but refused to say if the site is on the short list for sites that could be announced a few weeks from now.
  • South waterfront property owned by the Zidell family, known as Zidell Yards, has been discussed, according to the Portland Tribune.

PPS Superintendent Guadalupe Guerrero released a statement after PDP rescinded its offer.

"Our core mission remains focused on providing all of our students in Portland Public Schools with an excellent educational experience. Our centrally located headquarters is a highly attractive site for potential future development, and we will continue to evaluate any future opportunities that support our school system’s goals and better serves our community."
