Since 2016, Green Lake Conference Center has led the largest program of restoration since the Lawson-era buildings were constructed. In 2022, the Preserve Lawson Landmarks team joined the initiative and the projects they funded and led are marked PLL. All of  Green Lake Conference Center and Preserve Lawson Landmarks work has been achieved by donations of money and time to restore the buildings and walls for their next 100 years of life.
