The National Audubon Society, Inc., through its Connecticut program (Audubon-CT) is the sponsor of an "in-lieu fee" (ILF) program for aquatic resource compensatory mitigation required by Department of the Army authorizations. This program was approved by the New England District Corps of Engineers (Corps) and Audubon-CT on August 21, 2013. The program provides an alternative to Corps permittees who are required to compensate for their impacts to wetlands and waters of the United States in the State of Connecticut.
