Stream Restoration

HARP has over 15 years of experience in natural channel based stream restoration and enhancement for mitigation of impacts set forth by CWA 404/401 IP projects. In collaboration with trusted engineering and land survey partners, HARP has led stream design efforts for approximately 46,500 linear feet of streams and rivers for NC State DOT, NCDENR EEP, for various County and Municipal agencies (e.g. CMUD, and Forsyth/Winston Salem Utilities), and for private clients. HARP's early restoration projects (mid 1990's) were some of the first stream restoration projects in North Carolina undertaken using a natural reference reach approach and provided a test-bed for the NC DWQ's interim stream restoration protocols that were the predecessor to the current interagency North Carolina Guidelines for Stream Restoration. Urban watershed in particular presented some unique restoration challenges over rural streams, and from 2000 to 2003 HARP undertook to instrument a number of urban watersheds in Mecklenburg County to better define rating curves, return intervals, as well as bankfull and regime relationships so that designs would reliably meet the strict stability thresholds needed for restoration projects undertaken within built out urban watershed conditions. None of HARP's constructed restoration projects have failed monitoring criteria, a number of them have been closed out and 4 were closed out successfully after their 5th year of monitoring in 2012. Below are a few examples of some of HARP's projects wherein we provided initial assessments, natural channel design based measurements for use in design, construction oversight and monitoring.

HARP has assessed and restored more than 130 individual natural channel based restoration and bioengineering projects, in Mecklenburg County, Guilford, Forsyth, and Alamance counties of NC. HARP has prepared natural channel based restorations in Greenville and York Counties in SC. HARP's scientists can locate streams and evaluate their potential for mitigation, collect geomorphic and biological data, analyze the data and prepare restoration plans and natural channel designs based on reference reach data. In collaboration with engineering and survey partners HARP can provide design build services for stream restoration, wetland restoration and storm water BMPs. HARP has been studying the watersheds of Mecklenburg County and adjacent areas for more than 20 years. We possess a reference reach data base for natural channel based stream restoration of the area that is unrivaled. Our hydrologists, geologists and botanists understand stream geomorphology, watersheds and botanical communities and their interdependence. HARP's natural channel based design team lead by specialist Dr. Randall Forsythe is of the most innovative in the field. Our understanding of the science behind natural channel based restoration coupled with decades of experience and a dedication to solving stream and wetland challenges is unparalleled. HARP's stream assessment and natural channel design team utilizes Dr. Dave Rosgen's methodologies as well as methodologies specific to stream geomorphology in highly developed urban settings. HARP's team continually provides innovative solutions to our client's challenging problems.
