The Appendix on Political and Legislative Environment describes the legal framework which both limits and guides comprehensive water resource planning of Puget Sound and Adjacent Waters. The reader is provided with a summary of the back-ground, objectives, policies and operations of the agencies of the State of Washington and Federal Government having responsibilities for water and related land resources. These policies are, of course, premised on a changing and evolving pattern of law and legal philosophy. Accordingly, the explicit description of present agency policies and functions are followed by basic legal information with respect to the constitutions of the State of Washington and United States and their case law, legislation and regulations governing the development, and use of water and related land.
