Today’s preservation professionals are facing the task of documenting and evaluating the work of a whole new generation of masters in architecture, landscape architecture, and planning. Quinn Evans Architects is leading the field in creating the new vocabularies and historic contexts that future generations of professionals will use to evaluate their contributions. 
One of the largest categories of mid-century properties reflects the struggle of the era’s master planners to define and improve urban landscapes. The fruits of urban renewal, which demolished swaths of historic city fabric and sparked the historic preservation movement, are now, ironically, eligible to be considered for historic status. QEA is preparing a National Historic Landmark nomination for Lafayette Park in Detroit, one of the nation’s earliest urban renewal projects. Although Lafayette Park is chiefly known for its collection of Mies van der Rohe-designed residential towers and townhouses, our research establishes that the superblock plan by Ludwig Hilberseimer and landscape design by Alfred Caldwell were key to its unusual success compared to most urban renewal projects. QEA also successfully nominated another urban renewal-related property, the Fiberglas Tower in Toledo, to the National Register of Historic Places. 
QEA is also meeting the challenge of assessing buildings less than 50 years old, which are typically not eligible for historic designation. For the J. Edgar Hoover FBI Building in Washington, DC, this includes addressing complex issues such as the complicated history of the FBI, the impact of federal planning policies and local review processes on the design, and the significance of under-appreciated architectural styles such as Brutalism. As architects, historians, landscape architects, and other professionals explore the growing body of Modern work, QEA will continue to bring our deep understanding and knowledge of documentation and evaluation to the stewardship of a new era of historic properties. ■
