Regulatory Program Misson

Water is one of our nation’s most valuable resources. It is becoming increasingly important that we protect the quality of our inland waters and wetlands for the use and benefit of future generations.

The mission of the U.S. Army Corps of Engineers Regulatory Program is to protect the nation’s aquatic resources, while allowing reasonable development through fair, flexible, and balanced permit decisions.

Our Goals

The U.S. Army Corps of Engineers has been involved in regulating certain activities (i.e. navigation) in U.S. waters since 1890. Since then, new laws and judicial decisions have evolved the program to include consideration of public interest by balancing favorable impacts against detrimental impacts to Waters of the U.S. 

The Walla Walla District Regulatory Program strives reach the goals of the mission:

1.  To provide protection to the nation’s aquatic environment, including wetlands.

2.  To enhance the efficiency of the administration of the regulatory program.

3.  To ensure that the Corps provides the public with fair and reasonable decisions.
