Riverview Retirement Community, the Spokane-based nonprofit retirement complex operator, is looking to build a 20,000-square-foot facility dedicated exclusively to patients with memory care needs, according to a pre-development application filed with the city of Spokane.

Riverview marketing specialist Alison Hockett says the organization declines to comment about the project as it has yet to be finalized.

The initial pre-development application with the city calls for a single-story building to be built near Riverview’s existing retirement facility at 1801 E. Upriver Drive. The project’s estimated construction cost is $5.5 million.

In its 2015 annual report, the most recent such report posted to Riverview’s website, president and CEO Charles Tirrell, in his annual overview, said Riverview had completed an agreement with Avista Corp. to acquire a parcel of land adjacent to Riverview near the corner of Upriver Drive and Granite Street.

However, neither the pre-development application nor the annual report said the new building will be developed on the land acquired from Avista.

“This parcel provides Riverview a host of possible options as we build for the future. This is the first significant land acquisition in over a decade,” Tirrell said in the annual report.

The project calls for 20, single-occupant rooms, with two additional rooms allowing for a spouse or roommate. Spokane-based NAC Architecture is listed as the project architect.

Riverview offers assisted and independent living and advanced and rehabilitation care for its residents spread across its 32-acre campus, Riverview’s website says.

Riverview Retirement Community oversees operations of Riverview Terrace, Riverview Care Center, and Riverview Village, the organization says.

Riverview Terrace, which opened in 1959, consists of 135 studio, one-, and two-bedroom apartments. In 1997, the terrace’s first floor was remodeled to accommodate an assisted-living program. Riverview Care Center, a 75-bed facility, was built in 1967 and remodeled in 1989. In 1998, a dementia wing was added to offer continuing and long-term care.

Riverview Village is made up of 165 independent-living homes built between 1985 and 2014. The retirement community in 2013 built an aquatics and fitness center and a complete woodworking shop on the campus, the organization says.

Riverview Retirement Community reported having net assets of $49 million at the end of 2015, up from $48.3 million the prior year.
