In-lieu Fee Mitigation

In-Lieu Fee (ILF) Mitigation

In this approach to mitigation, a permittee pays a fee to a third party in lieu of, that is instead of, conducting project-specific mitigation or buying credits from a wetland mitigation bank. ILF mitigation is used to compensate for unavoidable impacts to wetlands when other approaches to compensation are not available, practicable, or when the use of an ILF is in the best interest of the environment.

The entity proposing to operate the ILF program (Sponsor) 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.  The fee charged by an ILF represents the expected cost of replacing the wetland functions lost or degraded as a result of the permittee’s project. An ILF program typically combines fees collected from one permittee's project with fees collected from other permittees' projects to finance a mitigation project.
