North Lot Development

• In February 2018, the construction at the East Parcel (Embassy Suite Hotel) was completed.
• In October 2012, the construction at the West Parcel (The Nolo) was completed.
• Post ground water and air monitoring is being conducted at this time.

In January 2014, Ecology, NLD and 255 South King Street LP signed a legal agreement called a Consent Decree (CD) for the new cleanup work at the East Parcel, completion of the work at the West Parcel, and document the work completed under the 2011 Prospective Purchaser Consent Decree. The new Consent Decree will supersede the 2011 Prospective Purchaser Consent Decree.

This Site is located north of CenturyLink Field, at the southeast intersection of South King Street and Occidental Avenue South in Seattle, WA.  The Site is approximately 3.85 acres.

The property originally was undeveloped tide-flats of Elliott Bay. The area was filled in the late 1890s and early 1900s and used as a rail yard until the late 1960s. Structures associated with the rail yard included engine maintenance buildings, paint shops, and track switching and material storage areas. In addition, two gasoline stations were formerly located in the northwest portion of the property at different times during the late 1930s and during the 1960s.

King County purchased the property in the 1970s to assist construction of the Kingdome stadium to the south of the property. The Kingdome was demolished in the early 2000s and replaced with the Century Link Field. The property has been used as a parking lot since the 1970s and as a staging area during the construction of the Kingdome and CenturyLink Field stadiums. 

The site is being cleaned up and developed as part of an Inter-Modal regional transit hub. This hub is adjacent to King Street Station with approximately 1.5 million square feet of buildable area. The Site includes the West Parcel (201 South King Street) and East Parcel (255 South King Street).
 
North Lot Development (NLD) has initiated cleanup and construction at the West Parcel, and has completed most remedial activities on the West Parcel except for groundwater compliance monitoring and implementation of institutional controls on the Site. The West Parcel development encompasses a full city block with residential, retail uses and four floors of above-ground parking. 
 
NLD sold the East Parcel to the 255 South King Street LP, and maintains ownership of the West Parcel. The 255 South King Street LP conducted remedial activities on the East Parcel as part of their commitment for cleanup and development. The East Parcel development encompasses a full city block with a high-rise hotel and a commercial office/retail building with one level of below-ground parking.
