County Line Mitigation Bank (CEMVR-RD-2022-0456)

Expiration date: 7/20/2022

The bank sponsor proposes to complete activities on 133.7 acres of privately owned property that would result in the establishment of stream, forested wetland, and emergent wetland mitigation credits. Establishment of the Bank will occur in two phases. Phase 1 will involve restoring floodplain wetland function through levee removal and improvement of associated wetlands and buffers in the east portion of the Bank. Phase 2 includes restoring the sediment filled floodplain wetlands and channels in the west portion of the Bank by grading low-lying areas and generating stream credits through the construction of bank protection and buffer establishment along the right descending bank of the Des Moines River. An off-site wetland delineation was completed in January 2021, in accordance with the1987 Wetland Delineation Manual and 2010 Midwest Regional Supplement. The off-site delineation found four potential agricultural wetlands currently used in commodity-crop production and a fifth potential wetland that includes a mix of agricultural and palustrine forested and possibly emergent wetlands. Of the 133.7 acres (52.4 acres west of the BSNF Railroad and 81.3 acres east of the BSNF Railroad) of the Bank, 32.6 acres were preliminarily assessed as either potentially jurisdictional palustrine forested wetland (7.9 acres) and/or agricultural wetland (24.7 acres). An on-site wetland delineation will be completed to help determine current conditions and the determination of credits prior to the submission of the draft mitigation banking instrument.
