AUGUSTA — The longtime head of Maine’s Land Use Regulation Commission has stepped down to become senior planner at the state’s Bureau of Parks and Lands.

Catherine Carroll was with LURC for 24 years, the last 10 as director. The agency regulates development in the state’s 10 million-acre Unorganized Territory

She says it’s a good time for her to go back to her first professional love of planning and managing public lands.

The Bureau of Parks and Lands and LURC are divisions within the Department of Conservation.

Gov. Paul LePage has appointed Samantha Horn Olsen, manager of LURC’s planning division, as acting director of LURC.
