Sanford Health will build two new clinics and an orthopedic hospital as part of a $209.5 million building plan over the next three years.

The health care system announced on Tuesday that it would be completing five projects, including its first clinic in the growing city of Harrisburg and a new clinic at the corner of East 57th Street and Hwy. 11, as well as massive expansions and additions to its main campus in central Sioux Falls.

"For us this is getting the message out that we are going to enhance our existing service lines," said Paul Hanson, CEO and President of Sanford Sioux Falls. "We see an opportunity where the community is growing."

The projects announced by Sanford this week are part of the health care system's effort to provide more services to parts of the city and the surrounding area that are gaining thousands of new residents each year.

The clinic at 57th Street and Hwy. 11 is in the farthest southeastern corner of the city, where development of new neighborhoods and massive apartment complexes has brought many new families to the area.

Sanford is the first to announce a project for the intersection. Its clinic there will measure 42,000 square feet and will be finished by 2021. Moving into that yet-undeveloped pocket of Sioux Falls will allow Sanford to serve more households in the city and the surrounding region, including patients from Brandon and northwestern Iowa, Hanson said.

The 16,000-square-foot Harrisburg clinic will break ground at Cliff Avenue and Willow Street this spring and is expected to be finished in a year, Sanford Health said in a statement.

"We view Harrisburg as a growing community, a progressive community," Hanson said.

Both the Harrisburg and East 57th Street clinics will have a Lewis Drug attached.

An orthopedic hospital at Sanford's main campus is also in the works, with the expectation that it will open by 2023. The 163,000-square-foot building will break ground in summer 2021 and will include 12 operating rooms.

The Sanford Heart Hospital is also undergoing a makeover this month, adding 26,058 square feet, including 16 additional patient rooms. It is expected to be finished by the end of the year.

Lastly, the Sanford Van Demark Building will also be expanded by 33,000 square feet beginning in fall 2020, with the goal of finishing by spring 2022. The expansion will add 23 exam rooms, space for eight additional surgeons and 12 advanced practice providers.

Sanford's expansive development plans for the next few years are part of the health care's rooftops strategy, which entails bringing services closer to Sioux Falls' residential neighborhoods, Hanson said.

"It's been a strategy we've had in place for decades," he said.
