Foreword 



These Economic and Environmental Principles and 

 Guidelines for Water and Related Land Resources 

 Implementation Studies have been developed to 

 guide the formulation and evaluation studies of the 

 major Federal water resources development agen- 

 cies. This document is the product of extensive 

 work by experts from a variety of professions and 

 was developed with the help of hundreds of com- 

 ments from the public. It contains the best currently 

 available methods for calculating the benefits and 

 costs of water resources development alternatives 

 accurately and consistently, and is intended to 

 ensure proper and consistent planning by the cov- 

 ered Federal agencies. I am confident that these 

 Principles and Guidelines will enhance our ability to 

 identify and recommend to the Congress economi- 

 cally and environmentally sound water project alter- 

 natives. 



In accordance with Section 103 of the Water Re- 

 sources Planning Act, as amended (42 U.S.C. 



1962a-2), the Water Resources Council voted on 

 September 9, 1982, to repeal the existing Princi- 

 ples, Standards and Procedures (18 CFR, Parts 

 711, 713, 714 and 716) and to establish these Prin- 

 ciples and Guidelines. The President approved the 

 Principles on February 3, 1983. In accordance with 

 Executive Order 11747 (38 FR 30993, November 7, 

 1973), I hereby approve the new Standards (Chapter 

 I) and Procedures (Chapters II and III).
