Stream Restoration
Kerr Environmental Services (KES) has played an active role in stream mitigation and the development of stream mitigation policy
in Virginia. Several of our staff have completed all levels of the extensive Natural Channel Design training taught by Dave Rosgen,
and have utilized these techniques in: stream restoration site evaluations, preliminary natural channel designs, final natural
channel design, and regulatory approval of Mitigation Banking Instruments. Our engineers validate our designs through hydraulic
analysis using TR-20 or TR-55 and HEC-RAS. KES also utilizes the Rivermorph ® stream
restoration software, AutoCAD, and ArcGIS to assist in stream assessment and design. KES has performed site searches in 12 Virginia
counties, and was involved in the stream mitigation bank approval process in both Virginia and North Carolina. We have performed:
Rosgen Level I and II assessments on 100 miles of streams (528,000 linear feet), feasibility studies for over 36 miles of streams
(190,100 lf), and designs for over 10 miles of streams, and secured approval for 3 mitigation banks. KES has also assessed seven (7)
Reference Reaches and calculated all dimensionless ratios necessary for design.
