Developing a Stream Assessment Protocol

CSS has been a significant contributor to the development and implementation of the Oregon Stream Function Assessment Method (SFAM) for more than 10 years. SFAM is a key component of the Oregon Stream Mitigation Program administered by the Oregon Department of State Lands.
The mitigation program is designed to address damage to aquatic resources caused by permitted activities, such as road construction, and commercial building. CSS employee owners have provided support for method development including field trials, data analysis, and expertise in developing the Excel-based stream assessment scoring tool. In addition, CSS employee owners helped write the SFAM Manual and Scientific Rational support document. Visit Oregon Department of State Lands website to learn more about this program.
