The U.S. General Services Administration says it has leased two floors in the Broadview Dairy building north of downtown, and that the U.S. Department of Homeland Security's Immigration and Customs Enforcement agency plans to move its Spokane offices there this winter.

Meantime, Huckleberry Bay Co., of Spokane, which owns the three-story Broadview Dairy building, at 411 W. Cataldo, has submitted plans for a renovation project valued at $2.5 million to prepare the second and third floors for the planned tenant, documents on file with the city of Spokane show.

Tom Barbieri, of Huckleberry Bay Co., an affiliate of Spokane-based Goodale & Barbieri Co., was unavailable for comment about the project.

The second and third floors of the Broadview Dairy building are vacant and have a total of 22,000 square feet of floor space.

Plans say that the upgrades would reconfigure space there for offices, interview and interrogation rooms, locker rooms, and a training room.

No tenant improvements are planned on the ground floor of the building, with the exception of a new entrance and an elevator, plans show. The 11,000-square-foot ground floor is occupied by Caterina and Lone Canary wineries.

The renovations will accommodate ICE's investigations unit and enforcement-and-removal operations, says Lorie Dankers, a Seattle-based spokeswoman for ICE.

The investigations unit handles child predator cases, gang-related investigations, and other alleged violations of immigration law, Dankers says. The enforcement-and-removal operations handles administrative immigrations violations, such as the presence of illegal aliens in the U.S., she says.

The Spokane ICE offices currently are located in the Thomas S. Foley U.S. Courthouse, at 920 W. Riverside, and across the street from there in leased space at 901 W. Riverside, says Ross Buffington, an Auburn, Wash.-based spokesman for GSA, an agency of the U.S. government that manages and supports certain functions of federal agencies, including real estate.

About 25 people will be moved to the Broadview Dairy building, Buffington says.

"We're going to co-locate existing operations," Dankers adds. "We won't be adding new staff. We've outgrown our space over the last several years, and we needed one location that fits our needs."

She says the investigations and enforcement operations had been part of separate services, but were combined under ICE in 2003.

The Broadview renovations also will include constructing an exterior fence with a combination of masonry supports, metal panels, and chain-link gates, which will secure the parking area on the south side of the building, plans say.

P. O'Connor & Associates, of Spokane, designed the project, although no contractor has been selected for it yet, plans say.

The Broadview Dairy building was constructed in 1910 and is listed on the Federal Register of Historic Places.
