Three Valley Conservation Trust
DRG conducted wetland and stream restoration at Hoffman Farm. Measures included stabilizing 1,000 linear feet of stream using bioengineered treatments, establishing a riparian buffer, and installing in-stream structures for improved water quality and habitat enhancement.
Improved Water Quality Through Restoration
The Three Valley Conservation Trust contracted Davey Resource Group, Inc. (DRG) to conduct wetland and stream restoration services at Hoffman Farm. The effort resulted in improved water quality through sediment and nutrient reduction as well as approximately 1,000 linear feet of stabilized stream using bioengineered bank treatments to halt erosion and prevent lateral migration. Bioengineered bank treatments included regrade, fabric and plant slopes, and a vegetated rock toe. DRG established a riparian buffer on cropland along the top of the left descending (north) bank of Indian Creek and installed native trees and shrubs to filter nutrients and sediments from surrounding agricultural runoff. Installing in-stream structures helped stabilize the project reach, improve sediment transport, provide grade control, and improve pool/riffle/run quality. The in-stream structures also assist with re-directing a portion of flood flows into the adjacent forested wetland along the south bank of Indian Creek to provide habitat enhancement and additional water quality improvement. Minor earthwork and grading were performed to re-contour portions of the floodplain, creating additional microtopography, followed by installation of herbaceous vegetation to improve habitat heterogeneity. DRG also removed invasive plant species before working in the forested wetland area.
