A medical office building that would have a personnel capacity of 300 to 400 people is proposed at 307 W. Fourth, according to early planning documents submitted to the city of Spokane.

The proposal currently is under environmental review as required by the State Environmental Policy Act for a project of its scope.

The development would consist of four office levels totaling 125,000 square feet above a six-level, 213,000-square-foot parking garage with 561 stalls and an additional service level. A portion of the property is occupied by a 44-stall surface parking lot that would be displaced. The rest of the site currently is vacant, environmental documents show.

Baker Construction & Development Inc., of Spokane, is listed as the contractor on the project, and Bernardo|Wills Architects PC, of Spokane, is designing it, other preliminary planning documents show.

Representatives for both companies couldn’t be reached immediately for comment.

Spokane County Assessor’s records show the project site is owned by South Spokane Mob Partners LLC, of Spokane, which also is listed on planning documents as the project applicant. The site, which includes three parcels totaling just over an acre of land on the southwest corner of Fourth Avenue and Bernard Streets, in the lower South Hill medical district.

According to SEPA documents, construction is projected to start late this year or in early 2019.

The building height is proposed to be 160 feet above Fourth Avenue and 130 feet above Fifth Avenue, and the exterior walls will be precast concrete panels with storefront window systems, planning documents show.

The project would be nearly twice the size of a $12 million development proposed in the spring of 2017 at that site for a six-story medical office structure with 68,000 square feet of office space and an adjacent five-story parking structure with 350 stalls, as earlier reported in the Journal.

At that time, the site was owned by Spokane-based GVD Commercial Properties Inc. State tax records show South Spokane Mob Partners bought the property last November for $1 million.

Prior to the GVD proposal, Baker Construction initially filed a predevelopment application with plans to construct a medical professional building at 960 E. Third, but that site didn’t work out.
