In-lieu Fee Mitigation

In-Lieu Fee Mitigation

In-Lieu Fee (ILF) mitigation is one type of mitigation that can be used to compensate for unavoidable impacts to wetlands. In this approach to mitigation, a permittee pays a fee to a third party instead of conducting project-specific mitigation or buying credits from a wetland mitigation bank. The fee charged by an ILF Program Sponsor (Sponsor) represents the expected cost of replacing the wetland functions lost or degraded as a result of the permittee's impact project.  An ILF Program typically combines fees collected from one or more impact projects to finance a mitigation project.

The Sponsor of an ILF program must be a non-profit organization such as a local land trust, private conservation group, or government agency with demonstrated competence in natural resource management.
