Block 18 Amazon Frontier

Site cleanup has been completed and a no further action (NFA) was issued in March 2023 for the Site. 

The Property is located in the Denny Triangle neighborhood of Seattle, WA.  It covers a full city block (Block 18) bound by 7th Avenue, Bell Street, Blanchard Street, and an alley in the Denny Triangle neighborhood of Seattle, Washington. 

The 0.9-acre-property was redeveloped from 2018 to 2021 for the construction of the Amazon Frontier Building, which is part of the Amazon campus.  The Amazon Frontier Building is a multi-level office building (16-story) with five levels of underground parking. 

The Property is located within the Denny Regrade area of Seattle (currently known as the Denny Triangle neighborhood). 

From 1897 to 1930, a major regrading and filling project occurred. It included the removal of Denny Hill, essentially reducing the elevation approximately 100 feet. 

During regrade activities, the land at and around the Property was cut in elevation up to 20 feet and subsequently filled with up to 25 feet of fill soil from nearby hills and other sources. 

Property was residential from about the 1900s to the 1930s.  A one-story retail building was present on the northern portion of the Property from the 1940s to 2018.  Former businesses in the retail building included an auto supply store, and an industrial supply store from the 2000s to 2011.  A four-story commercial building was located on the southern portion of the Property from 1950s to 2018. The building was historically used as a motel from 1958 to the 2000s, and as Cornish College dormitory from early 2010s to 2015.  The remainder of the Property was covered with asphalt parking.

The Property was redeveloped from 2018 to 2021 to the current configuration.  The redevelopment of the Property (Block 18) was one phase of a multi-office-tower redevelopment project that spanned five contiguous city blocks, known as Rufus 2.0 development.
