Building and maintaining the sustainable installation is one of the most challenging tasks facing the Army today. The Army has worked hard to establish a record of environmental compliance and stewardship on its properties. Urban sprawl has caused local civilian communities and Army installations to exist in closer vicinities, putting stress on both communities. On top of that, the Army has experienced an increase in its maneuver/training and equipment testing requirements. And, as has been the case historically, deteriorating natural resources, funding uncertainties, aging infrastructure, and other variables still challenge the Army's ability to maintain mission readiness while being a model steward of the environment.
