This old Nampa hospital sits vacant. What Saint Alphonsus now plans to do with it

After sitting vacant for nearly two years, the old Mercy Medical Center building in Nampa will be demolished.

The building has been empty since the new Saint Alphonsus Medical Center, adjacent to Interstate 84, opened in 2017. Saint Alphonsus Health System had tried to donate or sell the building, but the Nampa Hospital Board and Saint Alphonsus leadership ultimately decided to clear the site for redevelopment.

“It was our hope that the former Mercy Medical Center could find a new life, but ultimately, no viable plan came forward,” Lynda Clark, Nampa Community Hospital board chairwoman, said in a news release. “After trying for nearly two years to find another use for this building, the time has come to sell the land so a new community asset can take its place.”

The hospital, which opened in 1968, had 114 beds. It became part of the Saint Alphonsus Health System when Trinity Health purchased the hospital in 2010.

The 232,000 square-foot building sits on a nearly 19-acre site, which is zoned residential professional.

“They had discussions with a wide range of nonprofit, governmental and private sector entities to find a use for the building,” Nampa Mayor Debbie Kling said in a news release. “Since no solution was found, we’re in agreement with their decision, which is the highest and best benefit for the hospital system and the citizens of Nampa.”

Saint Alphonsus still has two emergency departments, primary and urgent care clinics and a new medical center in Nampa. It plans to open a cancer care center in the upcoming months.

“While we look back on the many years serving our patients inside the walls of the 12th Avenue hospital, we pay tribute to the great care received and the wonderful memories there that will never be forgotten,” Travis Leach, president of the Saint Alphonsus Medical Center in Nampa, said in a news release.

Saint Alphonsus is hiring a contractor for the demolition work and is completing an environmental assessment to prepare the site for sale. Once a contractor is selected, that company will apply to the city of Nampa for permits.
