Pacific Seafood, the Clackamas-based seafood processor, plans to build a state-of-the-art facility on the site where a former plant was located before it burned down June 4 on the North Oregon Coast. Demolition of the burned plant on the docks in Warrenton will reportedly take a month to complete. The new plant will allow more efficiency and higher quality products, according to company officials. Pacific Seafood has been operating temporarily at a leased facility on the Port of Astoria’s North Tongue Point.
