North Grand River
Wetland & Stream
Mitigation Bank

Terra Technologies has designed, constructed, and monitored a 145-acre Wetland and Stream Mitigation Bank located in rural Carroll County in north-central Missouri. This project transformed floodplain agricultural land that has been planted with row crops for several decades into functioning wetlands and riparian buffers. The habitats created on this site will be used to compensate for impacts to wetlands and streams by future projects in the bank's service area, which includes virtually all of Gentry, Harrison, Daviess, Caldwell, Mercer, Grundy, Livingston, Putnam, Sullivan, and Linn counties as well as parts of Worth, DeKalb, Clinton, Carroll, Chariton, Randolph, Macon, Adair, and Schuyler counties.

The design of the site includes 52 acres of riparian buffer restoration adjacent to onsite perennial and intermittent tributaries to Tater Hill Creek. Areas farther from the stream have soils that are more conducive for wetland development. Large amounts of microtopography throughout the poorly drained soils allows for the establishment of 21 acres of herbaceous wetlands onsite. Additionally, more than 67 acres of native upland buffers were established in the rolling hills which surround and protect the site's wetlands.

Terra Technologies' commitment to botanical diversity resulted in the seeding and planting of more than 100 tree, shrub, and herbaceous species on this site. The creation of berms and microtopography will result in a variety of microhabitats which will allow for the establishment of a wide diversity of plant species. The abundance of different plant species and water levels will produce a significant benefit to wildlife habitat.

Terra Technologies oversaw construction of this mitigation bank, and is currently monitoring the site. Construction was completed in 2009 and the mitigation bank was approved in 2016 by the US Army Corps of Engineers.
