Stream Restoration.
Year V events included additional well monitoring at the Grandover Wetland Creation
' and final stabilization at the Holden Road Stream Restoration. By copy of this final
monitoring report we respectfully request release of this project having met the five year
monitoring requirements and success criteria. Please feel free to contact me at (336) 288-
7180 should you have questions in regards to this report or require additional

Year 5 Monitoring Report S&ME Project No. 1588-02-044A & 44A
Grandover Wetland Creation/Holden Road Stream Restoration January 8, 2009
1.0 GRANDOVER WETLAND CREATION - HOLE #12 WEST
1.1 Onsite Conditions
Grandover Wetland Creation has successfully met the five years of monitoring criteria
' and continues to provide aesthetic value to the golf course, wildlife habitat, and water
quality enhancement to the upper stormwater pond and adjacent streams. S&ME met
NCDWQ representatives Eric Kulz and Tammy Hill on June 5, 2007 and USACE
' representative John Thomas on July 2, 2007 to review the wetland creation. Both DWQ
and USACE seemed to be pleased with the overall vegetative and hydrological function
of the creation but requested that monitoring for consecutive days throughout the growing
season be conducted to satisfy DWQ monitoring requirements. Monitoring well data is
included in the tables section of this report for the six onsite monitoring wells. Updated
photographs of the Grandover Wetland Creation are included in Appendix III.
'
1.2 Grading/Structures
' The cells appear to be functioning per design. Cell 1 was repaired during the Year 1
monitoring period and appears to have been functioning correctly since the repair. No
' additional grading or repair of structures is recommended based on the successful
function of the wetland creation.
' 1.3 Vegetation
A drawing of the as-built plantings for each cell is included in the Figures section of this
' report. The Grandover Wetland Creation was designed to have target wetland zones
including scrub/shrub, emergent/herbaceous, open water/aquatic zones, and bottomland
hardwoods. Bottomland hardwood species were designated along the southern edge of
' the wetland creation project with scrub/shrub and emergent/herbaceous species planned
for the majority of the project.
Vegetation data was gathered in September 2007 using six 60' diameter sample plots, one
in each of the five cells, and one located southwest of Cell #3. Vegetation plot locations
have remained consistent with plot locations chosen for 2006 monitoring. Longitude and
' latitude data for these points is listed on vegetative plot data sheets attached in Appendix
1. A location map depicting vegetative plot locations is attached as Figure 1.
' Vegetative densities ranged from 262 steins per acre to 786 stems per acre, with a mean
density in the sampling plots of 487 stems per acre. Only woody vegetation was included
in the stems per acre count. An informal survey of the remainder of the site indicates that
this level of success is apparent across the entire wetland creation area. It should be
noted that only the southern edge of the wetland creation was designed for bottomland
hardwood species

Grandover Wetland Creation/Holden Road Stream Restoration January 8, 2009
' 1.4 Monitoring Wells
Six onsite monitoring wells are maintained in locations shown in Figure 1. Monitoring
wells have not been moved from their initial monitoring positions; however; their depths
have been adjusted throughout the years to better meet the standard of 24 inches below
grade. Five monitoring wells are located in the wetland creation with one located on the
adjacent existing wetland. The longitude and latitude of monitoring well locations are
listed on vegetation plot data sheets, with each vegetation plot number corresponding to
' the monitoring well number. Although the wetland cells appear to stay saturated and/or
inundated throughout the year, at the request of DWQ the wells were monitored for 15
consecutive days during the Year 5 monitoring period. Monitoring data is represented in
' the Table 13. Monitoring wells 1 through 5 met a minimum of 11 consecutive days of
inundation or saturation within 12 inches of the soil surface. Monitoring well 6 did not
meet this criteria; however, it is not located within the wetland creation.
'
2.0 HOLDEN ROAD STREAM RESTORATION
2.1 Onsite Conditions
' Upstream development activities were completed during Year 5 of the stream restoration
project and site observations indicate the stream has recovered from temporary
sedimentation and construction debris associated with upstream land disturbing events.
S&ME met NCDWQ representatives Eric Kulz and Tammy Hill on June 5, 2007 and
' USACE representative John Thomas on July 2, 2007 to review the stream restoration
project. Both DWQ and USACE seemed to be pleased with the overall vegetation and
success of the restoration but requested that additional structures be used to help stabilize
several portions of the stream channel. A final repair event was conducted in Year 5
using boulders to better stabilize problem areas that have received multiple repair events
over the years. Updated photographs of the Holden Road Stream Restoration are
' included in Appendix IV.
' 2.2 Grading/Structures
In October 2007, final stream repair activities were conducted at the request of DWQ.
' The purpose of the repair event was to better stabilize problem areas with more rigorous
stabilization techniques such as placement of boulders in lieu of the past practice of
placing soil protection blankets and plantings. Boulders were used along the channel
' banks in several areas where more permanent means or stabilization was needed.
Reshaping of a natural stream bench was completed in the western portion of the
restoration as depicted in photographs 11 and 12 of Appendix IV. Soil protection
' blankets, native seed mix, and live stakes were also used in this area. S&ME has
continued to monitor Holden Road Stream Restoration site for signs of stability until
release of the project by regulatory agencies. Additional photographs of Year 5
monitoring are included in Appendix IV.

' 2.3 Vegetation
Vegetation data was gathered in September 2007 using six 60' diameter sample plots.
Vegetation plot locations have remained consistent with plot locations chosen for 2006
monitoring. Longitude and latitude data for these points is listed on vegetative plot data
sheets attached in Appendix II. A location map depicting vegetative plot locations is
attached as Figure 2.
Vegetation densities ranged from 385 stems per acre to 601 stems per acre, with a mean
density of 496 stems per acre. Only woody vegetation is included in the stems per acre
count. An informal survey of the remainder of the site indicates that this level of success
is apparent across the entire restoration area including the presence of many native
grasses. The use of live stake plantings over the years has helped to compensate for
woody vegetation losses during yearly repair events. Live stakes have proven helpful in
many areas for stream bank stabilization.
2.4 Cross Sectional Data
Cross sectional data for riffle and pool areas of both the restored stream reach and the
reference reach are attached in Appendix V. This data has been included for comparison
to the Year 1 and Year 3 Monitoring Reports. Overall channel cross sections have
become more incised and wider over the life of the project; however, they appear to have
stabilized over the past year after upstream construction activities were completed. At
the time of stream channel design, the amount of upstream development and its impact on
the restoration was underestimated. Three stream repair events were completed during
the 5 years of monitoring in order to compensate for stream stability that was influenced
by upstream impervious area.
3.0 CONCLUSIONS
By copy of this report, S&ME respectfully requests release of these two projects from
mitigation monitoring. Monitoring well data for the Grandover Wetland Creation
indicates the success criteria has been met, as evidenced by on-site conditions. Holden
Road Stream Restoration has been monitored beyond the Year 5 monitoring period to
determine that it has maintained its stability from the Year 5 repair activities. Holden
Road Stream Restoration has endured impacts from surrounding development and proven
itself as a long-standing channel. S&ME frequently observes evidence of wildlife use
within the project including aquatic wildlife and mammals such as raccoons and deer.
We expect the restoration project to continue to mature within its riparian corridor as
woody vegetation ages.
