1.0 EXECUTIVE SUMMARY/PROJECT ABSTRACT
The Goldsboro Housing Authority Mitigation Site (Site) is located in the northeast quadrant of the
intersection of NC -581 and US -13 within the West Haven Apartments complex owned by the Goldsboro
Housing Authority (GHA) in central Wayne County. As constructed the Site provides 799 stream
mitigation units. The Site is located in United States Geological Survey (USGS) Hydrologic Unit
03020201200020 (North Carolina Division of Water Quality Subbasin 03- 04 -05) of the Neuse River
Basin. The Site was identified to assist the North Carolina Ecosystem Enhancement Program in meeting
mitigation goals. Primary activities at the Site included stream enhancement (levels I and II), creation of
a Best Management Practice (BMP) constructed wetland, and replanting riparian areas with native
vegetation. Project restoration efforts provided 799 Stream Mitigation Units and 1 Stormwater Wetland
credit. This report summarizes data for year 2 (2010) monitoring.
The primary components of the restoration project included the following.
In keeping with the Neuse River Basinwide Management Plan developed by the North Carolina
Division of Water Quality, a major goal of the project is to reduce sediment and other water
quality stressors, nitrogen in particular, to the receiving watershed. This was to be achieved via
the following measures:
a. Restore channel dimension throughout the Site to include bank resloping, benching and
provision of reference appropriate width -depth ratios to reduce near bank stress and
attendant erosion, and to move bedload towards equilibrium, thereby preventing future
bank instability related to potential bed aggradation and /or degradation.
b. Replace the existing highly managed grass with an appropriate vegetated buffer
providing root mass that will stabilize project banks, treating both overland and
groundwater inputs.
c. Install a large stormwater wetland adjacent to Unnamed Tributary to Borden Field Ditch
( UTBFD) designed to intercept flows equivalent to one -inch of runoff from an area of
123 acres, which will provide a significant sediment and biogeochemical sink for the
inputs from the UTBFD watershed.
Attenuate storm flows and excess hydrologic energies associated with this highly urban
watershed via 1 a,b,c.
Enhance the natural aesthetic of the project corridor
Increase local awareness of natural resources in an urban setting and the conditions necessary for
their improvement/enhancement.
Based on interagency guidelines (USACE 2003), success criteria dictate that survival of woody species
planted at mitigation sites should be at a minimum density of 320 stems per acre at the end of the third
monitoring year. Subsequently, 290 stems per acre must be surviving at the end of year 4 and 260 stems
per acre at the end of year 5. Based on the number of stems counted, average densities were measured at
580 planted stems per acre surviving in year 2 (2010). The dominant species identified at the Site were
planted stems of river birch (Betula nigra) and sycamore (Platanus occidentalis). Supplemental planting
of the Site is scheduled to occur in the winter of 2010.
Success criteria for Site streams with an assurance that project goals are being achieved will primarily be
based on indicators and trends describing the stability of the channel and success of the riparian buffer. In
addition, a minimum of two bankfull events must be documented within the standard 5 year monitoring
period. In order for the monitoring to be considered complete, the bankfull events must occur in separate
monitoring years. Year 2 (2010) monitoring measurements indicate that there have been minimal

changes in the cross - sections as compared to as -built data. In addition, one bankfull event was
documented in the field to occur February 5, 2010 with a second bankfull event occurring on September
26 -27, 2010 after 4 inches of rain.
In summary, the Site achieved success criteria for vegetation and stream attributes in the Second
Monitoring Year (2010). Summary information and data related to the occurrence of items such as
beaver or encroachment and statistics related to performance of various project and monitoring elements
can be found in table and figures within this report's appendices. Narrative background and supporting
information formerly found in these reports can be found in the mitigation and restoration plan documents
available on EEPs website. All raw data supporting the tables and figures in the appendices is available
from EEP upon request.

2.0 METHODOLOGY
2.1 Vegetation Assessment
Following Site construction, three plots (20- meters by 5- meters) were established and monumented with
metal rebar at all plot corners. Plots were surveyed in June 2010 for the year 2 (2010) monitoring season.
Sampling was conducted as outlined in the CVS -EEP Protocol for Recording Vegetation, Version 4.0
(Lee et al. 2006) ( http: / /cvs.bio.unc.edu /nethods.htm); results are included in Appendix C. The
taxonomic standard for vegetation used for this document was Flora of the Carolinas, Virginia, Georgia,
and Surrounding Areas (Weakley 2007). The locations of vegetation monitoring plots are depicted on
Figure 2 in Appendix A.
2.2 Stream Assessment
Four permanent cross - sections were established after construction was completed. Measurements of each
cross - section include points at all breaks in slope including top of bank, bankfull, and thalweg. Riffle
cross - sections are classified using the Applied Fluvial Morphology (Rosgen 1996) stream classification
system. Cross - section plots and data are included in Appendix D; the locations of cross - sections are
depicted on Figure 2 in Appendix A.
