Interested parties are hereby notified that the District Engineers for the U.S. Army Corps of Engineers (Corps), Albuquerque and Omaha Districts, are authorizing the Colorado Mitigation Procedures and Colorado Stream Quantification Tool for use within the Albuquerque and Omaha Districts in the State of Colorado.

Colorado Mitigation Procedures – The Colorado Mitigation Procedures (COMP) establishes basic regulatory requirements for the use of stream and wetland functional assessments at impact and mitigation sites and describes the methods for quantifying stream and wetland credits and debits to satisfy regulatory requirements under Section 404 of the Clean Water Act within the Albuquerque and Omaha Districts in Colorado.

Colorado Stream Quantification Tool (Beta) – The Colorado Stream Quantification Tool (CSQT) is a functional assessment method that identifies a suite of stream functions and establishes standard operating procedures for collecting data on prospective stream impact and mitigation sites. The CSQT is an objective, measureable, and repeatable set of standard operating procedures based on quantitative data and field measurements which results in a functional foot score. The functional foot score will serve as a foundation to quantify changes in stream functions as a result of projects requiring permits under Section 404 of the Clean Water Act within the Albuquerque and Omaha Districts in Colorado. The CSQT is composed of a spreadsheet tool, a user manual, and a scientific support document.

The COMP and CSQT documents are available to the public on RIBITS. Due to security requirements, we cannot link directly to the district page. Please follow the instructions below to retrieve the documents.
