Maybe you want a certain laundry detergent. Or a specific brand of rice. Or a new laptop.

No matter what it is, it'll all be in a Troutdale warehouse the size of 40 football fields.

Amazon says it will pack "tens of millions" of items into its new, $180 million Troutdale fulfillment center when it opens this fall. Online orders from customers across the West will leave from the site in a Troutdale industrial park that once housed a Reynolds aluminum smelter.

When customers order something online, robots will pull the item from tightly packed storage in Troutdale and ferry it to human workers to pack, box and ship. The new facility will supplement existing facilities in California, Nevada and Washington, according to Amazon, adding to capacity to accommodate growing demand.

Amazon showed off the four-level warehouse, mid construction, on Tuesday. It has 2.3 million square feet of space, according to the company, and 16,000 tons of steel.

In time, Amazon plans to hire 1,500 to staff the facility. Hiring starts this summer at amazondelivers.jobs.

Amazon is rapidly becoming one of Oregon's largest private employers. It has a package sorting facility in Hillsboro and is opening distribution centers in North Portland and Salem this year, in addition to the new Troutdale site. Altogether, they will employ about 3,500.

Amazon's AWS Elemental subsidiary employs an additional 400 in downtown Portland, and the company also has dozens of employees at data centers in eastern Oregon.

The Intercept news site reported last week that in many states large numbers of Amazon warehouse employees are on food stamps. Oregon's Department of Human Services said it does not have the technical capacity to track where food stamp recipients work.

Amazon landed tax exemptions worth $9.6 million for its Troutdale site and agreed to pay workers at least 25 percent more than the minimum wage. That works out to $15 an hour. Amazon says it will offer benefits, including tuition assistance.
