The Environmental Law Institute's Compensatory Mitigation Research website: The Environmental Law Institute conducts detailed research to evaluate compensatory mitigation required to offset adverse impacts to wetlands. ELI studies a wide variety of compensatory mitigation programs, with a particular focus on compensatory mitigation carried out under Section 404 of the Clean Water Act. Within the Section 404 Program, ELI has analyzed all three available mechanisms, including mitigation banking, in-lieu fee mitigation, and permittee-responsible mitigation. 

Wilmington Stream Mitigation Website: This website includes stream mitigation guidelines, an assessment worksheet and other useful information on stream mitigation in the Wilmington District.

Mitigation Plan Development. An overview of the Mitigation Plan Development can be found on the Wilmington District website. It describes the elements of a SMART compensatory mitigation plan (Specific Measurable Attainable Reasonable (practicable) Trackable. It includes A Wetland Compensatory Mitigation Checklist and a Stream Compensatory Mitigation Checklist

Compensatory Mitigation Practices in the U.S. Army Corps of Engineers, Working Paper, March 2006
This paper reports on the current practice and status of compensatory mitigation authorized by the Corps of Engineers regulatory program. There is no existing comprehensive accounting or description of practices. The National Research Council (NRC) report on mitigation success, or lack thereof and described mitigation types several years ago (NRC, 2002). A year earlier, the Draft Report of the Nationwide Permit Programmatic EIS described mitigation decisions as of 2001, but focused primarily on nationwide permits. The Environmental Law Institute (ELI) proved a detailed description and status of two types of compensatory mitigation, mitigation banks and in-lieu fees as of 2001 (ELI 2002), but did not delve into the extent to which those mitigation services were used. This paper is intended to make available more recent data on compensatory mitigation practices authorized by the Corps of Engineers under permits issued under the auspices of Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act. This paper summarizes much of the data collected in a Corps of Engineers Institute for Water Resources (IWR) survey, hereafter referred to as the 2005 Corps Survey of District Mitigation Practices.
