The Renton, Washington-based office of Panattoni Development Co. is behind two Spokane-area distribution center developments valued at $63 million combined.

One is the $46 million, three-building West Plains Logistics complex planned on a 10-acre site at 10015 W. Hallett Road, about two miles southwest of Spokane International Airport and a half-mile west of the Interstate-90 interchange at Geiger Boulevard, west of Spokane. Site work is under way at the site.

The other development is the $17 million Green Acres Distribution Center under construction at 17710 E. Euclid, where concrete work is underway. The site is about a half-mile southeast of the Spokane Business & Industrial Park, in Spokane Valley.

Perlo Construction LLC, of Tualatin, Oregon, is the contractor on both developments, and Minneapolis-based Nelson Worldwide LLC designed them.

All of the buildings will be erected with tilt-up concrete construction.

Donnie Belk, senior development manager at Panattoni’s Seattle office, says the 192,000-square-foot Green Acres development will be the first to be completed.

“We are 100% green-lighted with deliveries to be starting this summer first with the Green Acres Distribution Center in Spokane Valley around July 1,” Belk says.

The West Plains Logistics development will have 528,000 square feet of industrial warehouse space on 28 acres of land.

Spokane County has issued building permits for two of the three structures planned for the West Plains site. One will have 87,300 square feet of space, and the other will have 256,200 square feet of space. Belk says they’re expected to be completed in September and October, respectively.

The third warehouse, a 184,000 square-foot structure, is expected to be completed in November, Belk says, although it hadn’t received permit approval as of earlier this month.

The spaces at both projects will be available for sale and lease. Belk says he’s seen an increase in interest in the spaces in recent weeks, although he expects construction will have to be further along before tenants commit to it.

“These are 100% speculative,” he says. “Everything is available.
