• Warehouse A: On Feb. 4, 2019, the city of Federal  Way issued its land-use approval for Warehouse A. Read the approval documents. Save Weyerhaeuser Campus is preparing an appeal of the decision. SWC is also appealing the SEPA (environmental) decision issued in October 2018. Several county, state and tribal agencies submitted written SEPA comments expressing concerns about traffic and the environment. Read their comments. The appeals will be combined and heard by the city's hearing examiner (the date has not been set).
  • Warehouse B: The city is continuing through the land-use permit review process for this warehouse, located on the south part of the campus, next to the proposed Warehouse A. Because it is located adjacent to Warehouse A and they share a stormwater pond, it's expected the environmental and land-use decisions on Warehouse B will follow shortly after those for Warehouse A.
  • Greenline Business Park: IRG's application for three warehouses, totaling more than 1 million square feet, on the north end of the campus, has triggered the requirement for a master drainage plan. This complex plan can take 1-2 years to complete. You can view documents on the city's site.
  • Comments on the business park application can be sent to  More than 725 community members signed a comment letter we facilitated and forwarded to the city.
  • Read project documents for all five warehouses on the city's site.
  • Comments can still be submitted to the city on any of the projects until decisions are issued. Email your comments or send to/drop them off at Federal Way City Hall.

Greenline Warehouse "A"

The latest proposal: A 225,950-square-foot general commodity warehouse with 264 parking spaces and 30 semi trailer stalls on 15.16 acres of land located on Weyerhaeuser Way, just north of Highway 18 and south of the campus headquarters building. The building will be 40-44 feet tall. A tenant has not been identified.

Traffic: A study estimates the warehouse will generate nearly 1,000 new vehicle trips daily. This includes 199 truck trips (26 trips during the AM peak hour and 20 during the PM peak hour) and 795 passenger vehicle trips (103 during the AM peak hour and 80 during the PM peak hour).Vehicle access: One access is planned for truck traffic, to channel semis from Highway 18 to the entrance just north of the interchange. No left turns will be allowed onto Weyerhaeuser Way. Passenger vehicles will access the warehouse and its offices via two driveways off the headquarters "loop road."

Design: Craft Architects has "included timber accents and artistic reveal patterns to emphasize the history and character of the area." Office entries that are visible from adjoining streets feature "large expanses of glass, glue laminated timber framing, facade modulation, large canopies and arcades."

Environmental issues: Wetlands will be filled and many significant trees will be cut, resulting in loss of animal and bird habitat. There may be impacts to East Hylebos Creek, which flows through Milton and Fife to the Tacoma tide flats. Noise and air pollution from semi-trucks servicing the warehouse are a concern.

What’s next: The city says the master use permit for a building on the property remains vested, even though the original tenant withdrew and the lot boundaries have been redrawn. The city issues a Mitigated Determination of Nonsignificance after its environmental review of the project. Save Weyerhaeuser Campus is appealing the decision and comments were submitted by county, state and tribabl agencies. The land-use decision is expected soon. The city's technical review letters can be read here: Jan. 28, 2018 letter, June 27, 2017 letter and Oct. 7, 2016 letter.

Public input: Closed.

Appeals: SWC has filed an appeal of the SEPA decision to the city's hearing examiner; we are expecting to appeal the land-use decision. No hearing date has been set.

Greenline Business Park

The proposal: IRG has applied to build three warehouses totaling nearly 1.1 million square feet on 146 acres that include the existing Greenline Technology Center building. The buildings will be 42 feet tall, and according to the environmental checklist, views looking north from South 336th Street will be altered by the sight of Buildings B and C.

The plan includes 1,446 parking spaces and 111 spaces for semi trailers. Access will be via four driveways off Weyerhaeuser Way. Five storm water ponds are proposed, including one on the east side of Weyerhaeuser Way, across from the project site. 

The site has 4,182 significant trees (175 of those in the required buffer) and 58 percent of them will be lost to construction.

Building A: 638,000 square feet, located north of the Tech Center.

Building B: 282,500 square feet, located south of the Tech Center.

Building C: 147,500 square feet, located south of the Tech Center.

Environmental issues: The site includes 63 wetlands and a man-made fish-bearing stream that is part of the Hylebos stream system, Issues include truck traffic, loss of forested watershed and habitat for animals and birds, filling of wetlands, effects on water quantity and quality in North Lake, which feeds the salmon-bearing East Hylebos Creek that flows through the campus and eventually into Puget Sound in Tacoma.

What's next: The city is reviewing IRG's application documents and working with IRG to develop the scope for the master drainage plan.
