Portland Diamond Project issued the following statement in response to the sale:

Our negotiations with ESCO regarding acquisition of its Northwest Portland industrial property did not comply with our ballpark development timelines. However, we look forward to working with the new owners to explore future opportunities. We will soon be sharing details pertaining to other Portland-area sites under consideration for ballpark district development.

The baseball group offered $80 million and a second piece of property to Portland Public Schools, for the district’s administrative headquarters two blocks from the Moda Center in Northeast Portland. Portland Public Schools said it is entertaining the offer.

On May 31, KGW learned that Portland Diamond Project inquired about a third site, at Terminal 2 in industrial Northwest Portland. The site is currently owned by the Port of Portland.

On June 1, Portland Diamond Project announced two new investors who significantly raised the profile of the project. Seattle Seahawks quarterback Russell Wilson and pop star Ciara signed on as investors. The married couple would become minority owners if the team materializes.

While the Portland Diamond Project has not revealed more details about the stadium design, they hired Populous Architects, as well as the local firm TVA Architects, to design the stadium.

There are estimates that it could cost between $700 million and $1 billion just to build a new stadium, not to mention costs of bringing either an existing MLB team or an expansion team to Portland. Cheek has estimated the total cost could be around $2 billion.
