Kent, Wash.-based Exotic Metals Forming Co. is considering constructing two more manufacturing facilities on its 56.6-acre property on west McFarlane Road, in Airway Heights.

The aerospace sheet metal fabrication and design company was issued a grading permit in late February to prepare the site for future expansion.

A representative of Exotic Metals couldn’t be reached immediately for comment.

Airway Heights-based Piersol Construction Inc. is the contractor on the site work.

Preliminary plans show each of the two envisioned buildings would be similar in size to the current, 150,000-square-foot facility the company currently operates at 12821 W. McFarlane Road.

The plans also show the company would add 150 parking stalls per phase to its existing 174 parking stalls and will create a network of road connections for ease of access to each facility. 

The company anticipates starting construction on phase one as early as this year, and for phase one to be completed by 2020. It is unclear when the company plans the second phase of construction.

Should the two-phase project move forward, the company anticipates hiring 150 employees per building.

The structures will be a maximum of 40 feet tall and will be constructed using concrete tilt-up panel construction, according to preliminary plans.

The Exotic Metals expansion proposal was subject to a state-required environmental review in September, and the company will be required to perform a traffic impact study before plans can move forward, according to city of Airway Heights planning records.

Exotic Metals must also get project approval from the city of Airway Heights and Spokane International Airport and Fairchild Air Force Base to ensure that the facilities will not impede airplanes taking off or landing, according to plans filed with the city. 

The Spokane International Airport terminal is roughly 4.5 miles away from the planned facilities, and Fairchild Air Force Base is about four miles away. The proposed facilities fall outside of the base’s accident potential zone, according to maps posted on the city of Airway Heights planning department website.

An accident potential zone is an area designated by the Department of Defense as a space that is subject to more aircraft accidents than others and should therefore remain undeveloped or sparsely developed to minimize damage should an accident occur.
