The Ahwahnee Principles are a set of guidelines that emphasize sustainable urban planning practices. These principles have developed alongside the New Urbanism movement, which incorporates mixed-use, walk-able, compact, and transit-oriented elements in community planning. They were developed by the California-based Local Government Commission in 1991, a group of architects and other professionals urban design. "Ahwahnee" is derived from a name for the Yosemite Valley in California. The Ahwahnee Principles have since expanded to other actions such as the Ahwahnee Principles for Economic Development (1997), the Ahwahnee Water Principle (2005), and the Ahwahnee Principles for Climate Change (2008) by the Local Government Commission.
