Project Location: The proposed site is located within Section 9, Township 77 North, Range 24 West, Warren County, Iowa.
Bank Objectives: The fundamental objective of compensatory mitigation is to offset environmental losses resulting from unavoidable impacts to waters of the United States (WOTUS) authorized by Department of Army Permits. Other Objectives include: stabilize streambanks, improve floodplain connection, reduce erosion; enhance and create additional wildlife habitat; restore native vegetation with riparian buffer; sell stream mitigation credits for projects developed by other entities.
Project Description/Bank Establishment: The bank sponsor proposes to complete activities on 15.14 acres of privately owned property that would result in the establishment of stream mitigation credits. The goal of this project is to restore 2,333 linear feet of an unnamed tributary to Middle Creek to generate an initial estimate of 31,448 stream credits. The bank sponsor proposes to use many different in-stream methods to aid in restoring these portions of stream, including re-meandering it to restore natural sinuosity to the channel and decrease the slopes. The sponsor also proposes to improve floodplain connectivity, install floodplain benches, and improve habitat by creating rock riffles within the stream. Improvements to the riparian buffer include vegetation management to remove invasive species and promote native species diversity. A wetland delineation was completed in August of 2022. One perennial stream, one emergent wetland, one forested wetland, and one drainageway were identified within the project area.
