While public-private partnerships (PPPs) have long been used to manage real property, congressional interest in PPPs has recently increased due to the large number of underutilized and excess buildings owned by federal agencies, as well as sequestration and other spending constraints. This book provides an overview of key policy and legal issues pertaining to PPPs for purposes of federal real property management. The book also discusses the potential for collocation and the factors that can affect that potential; the possible benefits of collocation; the the challenges associated with collocation, and what solutions, if any, can mitigate these challenges; the extent to which agencies attribute the full benefits and costs of their enhanced use leases (EUL) in their assessments of their EUL programs; and the experiences of agencies in using their EUL authority.
