On-call Services
In
February 2009, RJG&A was selected for inclusion on the EEP
on-call consultants list for the third consecutive time and has been
awarded
five separate two-year contracts since 2006. RJG&A
has performed post-construction tasks (viz., establishment of permanent
monitoring areas, installation of crest gauges, baseline data
collection, and mitigation plans) as well as annual geomorphic and
vegetative monitoring and reporting.

and Monitoring Firm for Greene Environmental Services (GES) Riparian
Buffer Restoration Projects RJG&A
has worked with GES since 2004, serving as the technical
advisors
on five riparian buffer restoration projects, monitoring the sites
annually, and producing the required end-of-year reports for EEP and
the North Carolina Division of Water Quality (DWQ). In 2008,
RJG&A helped GES establish
one of the first riparian buffer and nutrient offset credit mitigation
banks in North Carolina.

Woodchase
Subdivision
Wetland Restoration, Wake County, NC. As
compensatory mitigation for proposed wetland impacts in Woodchase, a
residential subdivision near Fuquay-Varina, RJG&A developed an
on-site
mitigation plan to restore 0.6 acre of forested riparian wetland. The restoration site was a
mowed powerline
right-of-way, decommissioned and replaced with underground powerlines. RJG&A
delineated all wetlands,
streams, and buffers on the project site, evaluated soils and
hydrology, and
inventoried wetland and upland plant communities under the powerline
and in the
adjacent woodlands. We
investigated soil
saturation depth zones, selected appropriate tree saplings and shrubs
for each
zone, and obtained USACE and NCDWQ approval for the mitigation plan. RJG&A staff
installed the plantings in
late fall, and documented high survival the following year during a
monitoring
visit with the Corps.
| | | Morgan Creek Stream
Stabilization Plan, Orange County, NC.
Morgan
Creek, which surrounds the OWASA Mason
Farm WWTP in Chapel Hill, became unstable in
1996 after Hurricane Fran eroded a bypass channel south of the WWTP,
reducing
the stream length by 2,600 feet and increasing stream gradient
three-fold. To
accommodate a proposed WWTP expansion and prevent further channel
erosion, both
onsite and off-site, RJG&A worked with the project
engineers, Brown and Caldwell and Skelley and Loy, to assess stream
stability and hydrologic conditions using
fluvial
geomorphic measurements and gauge data analysis, and developed a stream
stabilization plan that included partial filling of the bypass
channel
and in-stream structures to protect the original
channel. |
