Mr. Huggett:
As you are aware, the Department has monitored the Campbell Creek Phase I Mitigation Site
since its construction in April of 2006. Located in Beaufort County, the project site is
approximately seven miles east of Aurora off NC 33. The site was constructed to provide
compensatory mitigation to offset impacts for the Tetterton Road (SR 1963) project. The Phase I
site provided the following mitigation: 1.33 acres of brackish marsh creation, 18.11 acres of
brackish marsh preservation, 2.25 acres of tidal fresh water marsh creation, 4.98 acres of tidal
fresh water marsh preservation and 4.81 acres of uplands.
The site was monitored to provide compensation for 0.094-acre of unavoidable wetland impacts
associated with the Tetterton Road Division project. The wetland restoration area was graded to
the elevation of the adjacent marsh and planted with Cladium jamaicense and Juncus
roemeriamas. According to permit conditions, NCDCT was required to monitor the Campbell
Creek Phase I Mitigation Site for five years or until success criteria were met, with vegetation
and hydrologic monitoring conducted each year. After each growing season, annual monitoring
reports were submitted to the appropriate regulatory agencies via the Natural Environment Unit's
(NEU) website:
htty. Avivly. ncdot. org/doh/preconstruct/pe/near/Monitorirrg/MonitoringReports. html
Hydrologic monitoring success criteria required the establishment of hydrologic conditions
comparable in hydrologic frequency and duration to those of the existing reference wetlands
adjacent to the restoration area. Hydrologic monitoring utilized four surface water gauges
located on the site and one surface water gauge located in the adjacent reference area. The four

surface water gauges at the Campbell Creek Phase I mitigation site were compared to the
reference gauge. All four surface gauges indicated that inundation patterns were similar to that of
the reference gauge throughout the five year monitoring period.
The vegetative marsh success of the site was determined in accordance with NMFS Guidelines.
After five years of marsh vegetation monitoring, the percent of target species frequency is 96%
and the vegetative cover scale value is 4.8. Annual monitoring data is provided within the annual
monitoring reports submitted between 2006 and 2010.
A site visit was conducted on August 26"', 2010 with the regulatory agencies and NCDOT
personnel present. It was determined at that meeting that the site success criteria had been met
and that no further monitoring would be required. NCDOT requests that the appropriate resource
agencies provide written documentation stating that no further monitoring is required and that the
site is closed. Also, please see the attached on-site debit ledger for Campbell Creek Phase I
listing the TIP debits and remaining available credit at the site. If you have any questions about
this project, please contact Mr. Randy Griffin at (919) 431-6529.
