The Land Learning Foundation has requested approval for an In-Lieu Fee (ILF) mitigation project in Madison County, Missouri. The subject site consists of approximately 9.0+/- acres along the Castor River and an unnamed tributary. The Land Learning Foundation refers to this project as the Castor River site, and the U.S. Army Corps of Engineers (the Corps) has designated this project as MVS-2020-715.

The mitigation project includes the preservation and restoration of riparian corridor. Also,  work includes bank stabilization along the Castor River, reinforcement of an unstable crossing on the unnamed tributary, and grade control to prevent incising and restore riffle habitat to the unnamed tributary. Bank stabilization will use stream barbs and stone toe protection. Newberry style riffles will be used for grade control and to stabilize the stream crossing.

If approved by the Corps, the Castor River site will create a total potential mitigation credit release of 6,196.75 stream credits.   The Sponsor  would make the stream credits available to Department of the Army permittees seeking to fulfill requirements to purchase compensatory mitigation credit, in order to offset losses of aquatic functions and services.

The Corps solicits your comments on the proposed mitigation project, responses are due to this office no later than May 14, 2021.
