Spokane developer Harlan Douglass is moving forward with plans for a large commerce park adjacent to the Amazon fulfillment center on the West Plains.

Earlier this month, the Washington state Department of Ecology received an environmental review for the first phase of the project that includes construction of two warehouse buildings spanning a total of 176,000 square feet on 12 acres of vacant land at 5010 S. Thomas Mallen Road.

Douglass Commerce Park, at full build-out, will consist of 19 commercial warehouse, manufacturing, distribution and office buildings spanning 1.4 million square feet, according to the environmental review.

Construction of the project’s first phase is slated to begin in mid-summer and be completed by next year. Douglass intends to build two to three buildings per year until the project is complete.

Spokane-based Architectural Ventures is designing the project.
