St. Luke's Health System plans to open a medical plaza in Fruitland in spring 2014 as part of a "major expansion of medical services" in the area.

The $30 million health plaza will be the first phase of a $55 million project, and St. Luke's expects to break ground next month on it. The two-story, 80,000 square foot plaza will include a full-service 24-hour emergency room staffed by the same group of ER doctors that staffs St. Luke's ERs in Boise, Meridian and Nampa. The new ER is expected to bring 35 new jobs to Fruitland, bringing the total number of St. Luke's employees there to more than 100. Construction is expected to support more than 300 jobs.

The plaza also will include a walk-in clinic, lab services, diagnostic and medical imaging and doctor's offices.

St. Luke's said Tuesday that the plans for the second phase of the project aren't complete and will depend on fundraising to offset 10 percent of the $25 million expected cost. St. Luke's said the second phase would involve moving the Fruitland clinic of St. Luke's Mountain States Tumor Institute, which opened in 2002, and other outpatient services.

St. Luke's said it has operated a health clinic in a temporary space in Fruitland since 2010 in response to demand for more services.

"Our current clinic is at capacity," said Chris Roth, chief executive officer of St. Luke's Treasure Valley.

St. Luke's had more than 60,000 patient visits at the health clinic, MSTI clinic and family medicine practices in the Fruitland area last year, Roth said.
