UT Millers Creek Stream and Wetland Mitigation Site
The Neuse River Basin is a significant part of North Carolina's water supply, totaling over 6,200 square miles of drainage area and containing over 1 million residents. HDR | ICA provided the North Carolina Division of Mitigation Services (NCDMS) 2,600 feet of restored stream channel and 11 acres of restored wetlands at the UT Millers Creek Stream and Wetland Mitigation Site. Mitigation credits obtained from the restoration of streams and wetlands at the site will offset adverse impacts to jurisdictional streams and wetlands within the Neuse River Basin.
We identified a property with a stream that had been straightened and ditched as a result of historic agricultural practices. The manipulated stream was to be restored to stable geomorphic conditions. In addition to this, the property owner had excavated a large section of historically manipulated wetlands to build a pond and a large portion of the excavated spoil from the pond was wasted in manipulated wetlands within other portions of the site. We proposed to fill the pond and other manipulated areas to pre-disturbance grades in an effort to restore wetlands.
We met with the owner on multiple occasions to ensure that proposed mitigation activities would correspond with his property management plans and held meetings with the NCDMS, state and federal resource agencies, to present technical findings and clearly delineate proposed mitigation actions. These meetings allowed HDR|ICA to educate all regulatory agencies about our plan of mitigation and to receive feedback as we progressed the site through development
Currently, the site is designed, permitted and constructed. We've restored the channel into a more natural meandering stream using Natural Channel Design principals. Approximately 11 acres of wetlands have been restored to pre-disturbance grades in an effort to uplift aquatic, near-aquatic and terrestrial functions throughout the site and we're now conducting annual monitoring of the restored areas. Annual monitoring includes geomorphic analysis of the restored stream system, groundwater level monitoring using several gauges and vegetative analysis of planted trees and shrubs throughout the site.
