Dear Mr Kulz
Restoration Systems, LLC has completed the third year of monitoring (2012) 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 2012 Annual Report for the project is provided for your review and indicates that all
12 monitoring plots met the success criteria for stems per acre (320) The average for
stems per acre for the 2012 monitoring season is 853
If you feel that our project is in conformance with the Mitigation Plan please provide me
with a letter indicating such at your earliest convenience 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 Subbasm 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
I 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 As a whole the densities of vegetation
plots across the Site were above the required 320 stems per acre with an average of 853 planted stems per
acre in the Third Monitoring Year (2012) In addition each individual plot met success criteria based on
planted stems alone

12 Protect 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

Butlers Branch Nitrogen Buffer Restoration Site
As constructed Site activities restored historic riparian buffer functions by planting the entire 54 acre Site
with native riparian vegetation The 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 The following table outlines

20 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
21 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

22 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
23 Vegetation Sampling Results and Comparison to Success Criteria
Quantitative sampling of vegetation was conducted in June 2012 Vegetation success criteria (320 stems
per acre) were exceeded for the year 3 (2012) annual monitoring year with an average density of 853
planted stems per acre across the Site In addition each individual plot met success criteria based on
planted stems alone
30 CONCLUSIONS
As a whole the densities of vegetation plots across the Site were above the required 320 stems per acre
with an average of 853 planted stems per acre in the Third Monitoring Year (2012) The following table
summarizes planted stem data throughout the monitoring period
