NOTICE OF AVAILABILITY FOR THE COMPENSATORY MITIGATION (CM) ELIGIBILITY AND ACCOUNTING DETERMINATION WORKSHEET DEVELOPED FOR USE WITH THE IDAHO STREAM FUNCTION ASSESSMENT METHOD (SFAM)

U.S. ARMY CORPS OF ENGINEERS, WALLA WALLA DISTRICT
Published Feb. 2, 2026
Expiration date: 2/2/2027
PRINT | E-MAIL

This worksheet is intended to address compensatory mitigation for streams in Idaho. The Idaho version of this form closely follows the methods developed for Oregon, with modifications made to reflect Idaho-specific data sources, and recently available data and research.

The eligibility worksheet is used to determine whether a proposed compensatory mitigation site is ecologically appropriate to offset proposed impacts. Final eligibility is determined by the agency. The expectation is that compensatory mitigation sites provide an ecological match (i.e. class, function, and value) to the impact site. In some circumstances, an exception to ecological match may be allowed if the permittee demonstrates that the proposed compensatory mitigation site addresses local or watershed needs or priorities.

The CM Eligibility and Accounting Determination worksheet provides detailed instructions for using the two SFAM Credit-Debit worksheets for the impact site and the mitigation site. The CM Eligibility & Accounting worksheet also includes a small summary table at the bottom that links to the two Credit-Debit worksheets and compares the debits and credits generated on those worksheets.

A link to the CM Eligibility & Accounting Worksheet can be obtained from the District’s website at https://www.nww.usace.army.mil/Business-With-Us/Regulatory-Division/Mitigation/: or by clicking here.

The Corps is soliciting comments from the users’ experience with implementing the CM Eligibility & Accounting worksheet, beta version 1.0, during a one-year period (February 2026-February 2027). In particular, we are interested in: 

  • Problem situations encountered and possible approaches for addressing them.
  • Apparently incorrect results, including the factors that suggest formulas in the worksheet are inaccurate.
  • Regional differences in the applicability of specific indicators.
