Subject: Butlers Branch Year 1 (2010) Monitoring Report
Dear Mr. Kulz:
Restoration Systems, LLC has completed the first year of monitoring (2010) for the
Butlers Branch Buffer Restoration Project for the City of Raleigh. As stipulated in our
contract with the City of Raleigh, the City requires the Division of Water Quality to
acknowledge that the project is still in conformance with the Mitigation Plan prior to
approving invoices resulting from annual monitoring efforts.
The 2010 Annual Report for the project is provided for your review and indicates that 11
out of the 12 monitoring plots met the success criteria for stems per acre (320). The
average for stems per acre for the 2010 monitoring season is 860. Plot 2 is the only plot
where the planted stems did not meet the average but we fully expect this plot to meet
monitoring success in 2011 with the addition of volunteer species.
At your earliest convenience, please provide me with a letter indicating that the DWQ has
reviewed the 2010 monitoring report and finds the project to be in compliance with the
Mitigation Plan. If you have any questions concerning this report please contact me at
919-334-9112.

EXECUTIVE SUMMARY
Restoration Systems, LLC has completed riparian buffer restoration at the Butlers Branch Nutrient Buffer
Restoration Site (hereafter referred to as the "Site") for the City of Raleigh's wastewater treatment facility
on the Neuse River (NPDES Permit NC0029033). Within the Site, approximately 54 acres of headwater
buffer habitat were restored providing 4091 pounds of nitrogen offsets per year for greater than 122,742
pounds of nitrogen offsets over 30 years to the City of Raleigh. The Site is located approximately 17
miles east of the Town of Kinston in Craven County within United States Geological Survey Hydrologic
Unit 03020202080020 (North Carolina Division of Water Quality Subbasin 03-04-08) of the Neuse River
Basin.
The Site includes three main tributary systems that drain directly to the Neuse River (Village Creek and
two unnamed tributary systems). Prior to construction, the Site was characterized by agricultural fields
and disturbed forest, and Site streams were regularly dredged and cleared of vegetation. Land use
practices including the maintenance and removal of vegetation, regular plowing, and use of agricultural
chemicals had resulted in degraded water quality.
The goals and objectives of this project focused on improving local water quality, improving bank
stability, supporting in-stream habitat through the contribution of large woody debris, and maintaining
wildlife passage corridors. These goals were accomplished by the following.
1. Removing nonpoint sources of pollution associated with agriculture production by a) ceasing the
application of agricultural herbicides, pesticides, fertilizers, and other agricultural materials into
and adjacent to Site ditches and open waterways and b) providing a vegetative buffer adjacent to
ditches and waterways to treat surface runoff that may be laden with sediment and/or agricultural
pollutants.
2. Reducing sedimentation/siltation within on-Site and downstream receiving waters by a)
increasing retention time for surface waters entering and leaving the Site, b) reducing erosion
associated with vegetation maintenance and agricultural plowing to Site ditches, and c) planting a
forested vegetative buffer adjacent to Site ditches and waterways.
3. Promoting floodwater attenuation by ripping compacted soils and revegetating the Site to increase
frictional resistance on floodwaters crossing the Site.
4. Providing terrestrial wildlife habitat including a forested riparian corridor within an area that was
previously cleared and highly dissected by agricultural land use.
This project was constructed in late winter/early spring 2010. Planting of the entire 54-acre Site will
provide 4091 pounds of nitrogen offsets per year for greater than 122,742 pounds of nitrogen offsets over
30 years to the City of Raleigh. As a whole, the densities of vegetation plots across the Site were above
the required 320 stems per acre with an average of 860 planted stems per acre in the First Monitoring
Year (2010). In addition, each individual plot met success criteria based on planted stems alone with the
exception of Plot 2; however, when including naturally recruited stems of appropriate species this plot
was well-above success criteria with 729 stems per acre.

1.2 Project Goals and Objectives
The goals and objectives of this project focused on improving local water quality, improving bank stability,
supporting in-stream habitat through the contribution of large woody debris, and maintaining wildlife
passage corridors. These goals were accomplished by the following.
1. Removing nonpoint sources of pollution associated with agriculture production by a) ceasing the
application of agricultural herbicides, pesticides, fertilizers, and other agricultural materials into
and adjacent to Site ditches and open waterways and b) providing a vegetative buffer adjacent to
ditches and waterways to treat surface runoff that may be laden with sediment and/or agricultural
pollutants.
2. Reducing sedimentation/siltation within on-Site and downstream receiving waters by a) increasing
retention time for surface waters entering and leaving the Site, b) reducing erosion associated with
vegetation maintenance and agricultural plowing to Site ditches, and c) planting a forested
vegetative buffer adjacent to Site ditches and waterways.
3. Promoting floodwater attenuation by ripping compacted soils and revegetating the Site to increase
frictional resistance on floodwaters crossing the Site.
4. Providing terrestrial wildlife habitat including a forested riparian corridor within an area that was
previously cleared and highly dissected by agricultural land use.
1.3 Project Structure, Restoration Type, and Approach
The Site includes three main tributary systems that drain directly to the Neuse River (Village Creek and
two unnamed tributary systems). Prior to construction, the Site was characterized by agricultural fields and
disturbed forest, and Site streams were regularly dredged and cleared of vegetation. Land use practices
including the maintenance and removal of vegetation, regular plowing, and use of agricultural chemicals
had resulted in degraded water quality.

2.0 MONITORING PLAN
Monitoring of Site restoration efforts will be performed for vegetation components of the Site for five years
or until success criteria are fulfilled. After planting was completed, an initial evaluation was performed to
verify planting methods were successful and to determine initial species composition and density. Twelve
sample vegetation plots (10-meter by 10-meter) were installed within the Site as per guidelines established
in CVS-EEP Protocol for Recording Vegetation, Version 4.0 (Lee et al. 2006). In each sample plot,
vegetation parameters to be monitored include species composition and species density. Visual
observations of the percent cover of shrub and herbaceous species will also be documented by photograph.
2.1 Vegetation Success Criteria
Characteristic Tree Species include woody tree and shrub species planted at the Site (Table 2) or outlined
for the appropriate plant community in Schafale and Weakley (1990). An average density of 320 stems per
acre of Characteristic Tree Species must be surviving after year 5 monitoring.

2.2 Maintenance and Contingency
In the event that success criteria are not fulfilled, a mechanism for contingency will be implemented. If
vegetation success criteria are not achieved based on average density calculations from combined plots
over the entire restoration area, supplemental planting may be performed with tree species approved by
regulatory agencies. Supplemental planting will be performed as needed until achievement of vegetation
success criteria.
2.3 Vegetation Sampling Results and Comparison to Success Criteria
Quantitative sampling of vegetation was conducted in September 2010. Vegetation success criteria for year
1 (320 stems per acre) were exceeded for the 2010 annual monitoring year with an average density of 860
planted stems per acre across the Site. In addition, each individual plot met success criteria based on
planted stems alone with the exception of Plot 2; however, when including naturally recruited stems of
appropriate species this plot was well-above success criteria with 729 stems per acre.
3.0 CONCLUSIONS
As a whole, the densities of vegetation plots across the Site were above the required 320 stems per acre
with an average of 860 planted stems per acre in the First Monitoring Year (2010).
