Crooked Creek ILF

Published March 4, 2019

As described in the attached Public Notice, the Missouri Conservation Heritage Foundation - Stream Stewardship Trust Fund (Sponsor) has requested approval for an in-lieu fee (ILF) mitigation project in Bollinger County, Missouri.  The project site encompasses a reach of Crooked Creek, a perennial tributary approximately 39 miles from the confluence of the Headwater Diversion Channel. The Sponsor refers to this project as the Collier (SSTF 1014) Site, and the U.S. Army Corps of Engineers (the Corps) has designated this project as MVS-2018-305.  The project proposes to restore, protect, and maintain 5,170 linear feet of perennial stream channel and wooded riparian corridor along Crooked Creek. The restored and preserved corridor will generally extend 125-147 feet perpendicular from the channel banks.  This consists of tree plantings and the removal of any invasive species. The stabilization component of the project will restore bank stability to approximately 600 linear feet of channel with actively failing, near-vertical banks.  The proposed stabilization consists of the installation of five bendway weirs, longitudinal peaked stone toe protection, and a single rock vane.  If approved by the Corps, the Collier (SSTF 1014) site will create a total potential mitigation credit release of 8,770.5 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, to offset losses of aquatic functions and services.  The Corps solicits your comment on the proposed mitigation project.  Responses are due to this office no later than March 21, 2019.
