In November 2017, the National Trust for Historic Preservation launched its African American Cultural Heritage Action Fund, a preservation campaign to preserve and protect places that have been overlooked in American history and represent centuries of African American activism, achievement, and resilience. Since launching the program, the Action Fund has raised $70 million and supported more than 200 preservation projects nationally.

Through this preservation effort—the largest ever undertaken in support of African American historic sites— the Trust partners with and empowers Black and diverse communities to expand the American story.

Since October 2021, Amber has served as a thought leader and member of the interpretation team for the Sojourner Truth Memorial Project in Akron, Ohio. Summit Suffrage Centennial Committee, which oversees the project, secured financing from the John S. and James L. Knight Foundation in addition to the Action Fund. The Memorial Project will include a landscaped park with a sculpture created by Akron artist Woodrow Nash and a plaza laid out by Summit Metro Parks landscape architect Dion Harris. It will be located on South High Street near the place where Truth delivered her famous speech May 29, 1851, at the Ohio Women’s Rights Convention in the Universalist Old Stone Church.
