And you thought a 314,000 square-foot fish processing plant was huge.

The city of Federal Way has received a request for a pre-application meeting to discuss the building of a 721,000-square-foot warehouse and office building on Industrial Realty Group land, which was previously owned by Weyerhaeuser Company.

This is weeks after the community was notified that applicant Chill Build Seattle proposed the building of a 7.2-acre warehousing, distribution and processing center for Preferred Freezer Services and Orca Bay Seafoods, Inc.

Received by the city on Aug. 3, Eric G. LaBrie, president of ESM Consulting Engineers, LLC, submitted a letter requesting the meeting on the proposed development, which will sit on an approximately 50-acre site on three parcels of land. The applicant is listed as KG Investment Properties, a Bellevue commercial real estate firm that was awarded management of The Bravern Office Commons, which is fully leased by Microsoft. The investment firm also manages over 7 million square feet of office, industrial and retail properties around the Puget Sound region, and they’ve developed and invested in other properties as well.

City spokeswoman Cathy Schrock said the pre-application meeting will be held Sept. 1 and is not open to the public because it’s through an internal process with the Development Review Committee. The meeting will include city staff from various departments as well as representatives from Lakehaven Utility District and South King Fire and Rescue.

“It’s so they have an ability to get feedback from all the players,” Schrock said about the developer.

LaBrie, in an interview, said he didn’t know for what the large warehouse and office building would be used, but he said ESM Consulting has acted as the planning consultant for Industrial Realty Group, which has helped Industrial Realty Group understand city requirements.

The site is currently developed with asphalt parking lots that serve the Weyerhaeuser Technology Center. There are also large evergreen and deciduous trees. According to the letter, a portion of the parking lot may be relocated and reconfigured to accommodate the new warehouse, office space and parking.

The 1,300-by-550-foot single-story warehouse and office building will include 162 dock doors and four “drive-ins.” Just over 475 parking stalls, “100 of which will be for trailers,” are proposed, but LaBrie said in the letter that they “are aware that the proposal does not meet the parking requirements for the size of the proposed uses” and explains that that amount will “meet the needs of the future tenants.”

He added, “While the parking modification request will be included in the Process III application at the time of submittal, we would like to understand the city’s receptiveness to such a request as soon as possible.”

To mitigate the traffic coming from those 450-plus parking spots, the developer is proposing four access points: Two 40-feet driveways (so trucks can turn) will be added to Weyerhaeuser Way South, and two will be created after the parking lot is reconfigured for the Weyerhaeuser Technology Center.

While the zoning requires a forested buffer along part of the project, which will be 100 feet, the applicant doesn’t propose a forested buffer on the boundary that abuts Office Park zoning, which includes Aerotek, because “the proposed uses are compatible.” They will, however, include a 10-foot land buffer between the two buildings.

The project’s 50-acre site is among the 430 acres Weyerhaeuser Company sold to Industrial Realty Group in February for $70.5 million. Weyerhaeuser announced in 2014 it would move its corporate headquarters from Federal Way to Seattle in the middle or later part of this year.

While the Mirror could not confirm when the application will be filed, the letter indicates the applicants intend to submit the next round of required documents, a Process III land use application with a SEPA checklist, “in the near future.”

The Mirror will update this report as more information becomes available.
