ST. PAUL — The governing authority that will oversee Mayo Clinic’s ambitious Destination Medical Center expansion is getting filled out.

Gov. Mark Dayton planned to name four picks to the eight-member board on Tuesday. State law gave various entities 60 days to make their selections, which means the deadline has arrived. Dayton says he has consulted with Mayo prior to naming the appointees.

The board of the nonprofit corporation is responsible for adopting the development plan that will guide the multi-billion expansion being aided by a public subsidy.

Dayton’s four selections will join Rochester’s mayor, the city council president, an Olmsted County board designee and a Mayo appointee.

The board will be covered by the open meeting law and state records laws, and its members will be able to collect expense allowances.
