HRA prepared a book-length, illustrated manuscript titled Managing a Land in Motion: An Administrative History of Point Reyes National Seashore, which the NPS published in 2007.

HRA historians researched and wrote a 200-page administrative history update of the US Army Corps of Engineers, Baltimore District, covering the years 1974 to 2008. The history explained the district’s transformation from its early focus on flood control and transportation improvement to its emerging environmental missions, such as ecosystem restoration and cleanup of formerly used defense sites.

In 2004, the U.S. Army Corps of Engineers selected HRA to research and write a history of water management in South Florida and the Everglades. In 2010, the Corps asked HRA to add an epilogue covering the recent implementation of the Central Everglades Restoration Plan. Publication of River of Interests: Water Management in South Florida and the Everglades, 1948–2010, occurred in 2011.

In 2006, the U.S. Army hired HRA to conduct oral history interviews, perform research, and write a book detailing the history of the Army’s momentous Residential Communities Initiative (RCI) Program. The Army tasked HRA with collecting and telling the story of the pioneering privatization program to improve quality of life for soldiers and their families. The interviews became source material for writing Privatizing Military Family Housing: A History of the U.S. Army’s Residential Communities Initiative, 1995–2010.
