Terra Technologies has designed and constructed a Wetland and Stream Mitigation Bank in Gasconade County, Missouri. This unique site surrounds a low-lying area bordering a shallow intermittent swale that originates onsite and flows in two directions from its most uphill point. Historically, this site has been in agricultural production for many years and was likely logged for green ash lumber.
Terra Technologies recognized the potential of this site as the local topography, poorly drained soils and shallow swale presented an opportunity to spread the water carried by the swale across a wide area through the proper placement of berms and through the excavation of the surrounding areas. Additionally, excavation and microtopography capture runoff and subsurface flows from the surrounding Ozark hills.
This site contains approximately 29 acres of created riparian corridor and 11 acres of wetlands surrounded by upland prairie and forest buffers. The herbaceous layer in parts of the restoration areas had a high level of diversity, but the tree layer contained only a handful of species. Additional herbaceous species have been planted and numerous tree and shrub species have been introduced to the site to drastically enhance the wooded diversity. In addition, some areas in fallow fields surrounding the low-lying area have been excavated and planted with the same diverse mixture of appropriate native wetland species.
Terra Technologies oversaw the construction of the site, will monitor the progress of the restoration, and will sell the resulting wetland and stream credits to third parties. The bank service area will encompass the Gasconade River watershed which includes parts of Gasconade, Osage, Maries, Pulaski, Phelps, Dent, Texas, Laclede, Wright and Webster Counties.
Construction was completed in 2008.
