Inc. (NASDAQ: AMZN) is preparing to grow its brick-and-mortar retail presence along one of D.C.’s growing retail corridors: 14th Street NW.

The e-commerce giant has signed a lease for more than 8,000 square feet for one of its retail concepts at 14th and Riggs streets NW, according to a source familiar with the deal. Amazon declined to comment.

The Amazon concept will join several other previously announced retail tenants, including Sephora, Bluestone Lane and Parachute Home, at Liz, the mixed-use project from Whitman Walker Health and Fivesquares Development at 1701 14th St. NW.

Amazon has been testing out several brick-and-mortar retail concepts in the U.S., including an Amazon Bookstore, Amazon Go convenience store, Amazon Grocery, and Amazon 4-Star, which sells only products rated four stars or higher on Amazon’s website. The retailer had been eyeing 14th Street for its Amazon Go concept, according to a second source with knowledge of the talks.

The company, which is in the process of standing up its second headquarters in Arlington, has already rolled out its Amazon Bookstore concept in Georgetown and Bethesda, and opened an Amazon Hub pickup location outside of the University of Maryland campus in College Park.

There is also talk the company is looking to bring a new concept, an Amazon Grocery store — not a Whole Foods Market, which it also owns — to Greater Washington, among other locations. The Wall Street Journal reported last week Amazon had already signed leases for the grocery concept in Los Angeles, Chicago and Philadelphia.

Amazon Go stores are a convenience market with groceries, fresh food and prepared food items, among other necessities, that are largely cashier-less, allowing customers to scan their phones and pick up items they then pay for via the Amazon app.
