It looks like the planned fourth store in Portand, Oregon has been cancelled due to problems with a local commission. This is the same thing that happened to the Flatiron project in New York.

For the second time in nine months Apple has cancelled plans for a new store after local officials criticized the stores proposed architecture. According to an article by Daily Journal of Commerce (Portland, Ore.), Apple has decided not to pursue the store proposed for 437 N.W. 23rd Ave. in that city. Apple and Holst Architecture presented their original design to the citys Historic Landmarks Commission in early February, but their proposal was met with pointed criticism. A second design presented to the commission in mid-June was similarly received. Apple abandoned plans for a Flatiron district (NYC) store last September after the Community Board for the Ladies Miles Historic District, and the citys Landmarks Preservation Commission criticized the all-glass storefront.
