The National Park Service is asking for feedback from the public before they make major upgrades to the Lincoln Memorial for its centennial anniversary in 2022, according to an NPS release.

NPS will host a meeting to introduce the renovation plan to residents on June 27 at NPS headquarters in Southwest, D.C. and people can comment about the plan online on the project website until July 10.

The renovation proposal would expand the area below the memorial, moving the museum store to the lower level and allowing more space for retail and storage, while also improving accessibility with wider doors, more bathrooms and a second elevator. Renovators proposed expanding the underground portion by 15,000 square feet to also showcase the history of the construction of the memorial from 1914 to 1922 and provide more exhibits on President Abraham Lincoln.

Last fall Philanthropist David Rubenstein donated $18.5 million to the project, according to the Washington Business Journal. The park service requested an additional $2.2 million from the federal budget to replace the memorial’s roof.
