The Prince George’s County Council on Tuesday unanimously approved the nomination of John Shoaff, a University Park resident with an environmental background, to the county planning board.

He will replace Sarah A. Cavitt, a board member appointed by former County Executive Jack B. Jackson. Cavitt, a longtime civic activist, was known for environmental activism during her time on the board.

“I do indeed have some large proverbial shoes to fill,” Shoaff said.

Shoaff said his goal was to “prevent problems where possible, find creative solutions,” while “striving to find sustainability.”

Shoaff, who works for the Environmental Protection Agency, is the fourth appointee made to the board in the last several months. His appointment is part of County Executive Rushern L. Baker III’s overhaul of the five-member panel.

Shoaff will join newcomers A. Shaunise Washington, Dorothy F. Bailey and former chairman Elizabeth M. Hewlett on the board.

The planning board reviews commercial and residential development plans that are sent to the council for review and approval.
