January 2014 FINAL ANNUAL MONITORING REPORT GOOSE CREEK STREAM RESTORATION DURHAM COUNTY, NORTH CAROLINA (EEP Project Number 147, Contract Number 004681) Construction Completed September 2008 Monitoring Year 5 of 5 (2013) Submitted to: North Carolina Department of Environment and Natural Resources Ecosystem Enhancement Program Raleigh, North Carolina Prepared by: Axiom Environmental, Inc. 218 Snow Avenue Raleigh, North Carolina 27603 Design Firm: Biohabitats 8218 Creedmoor Road Raleigh, North Carolina 27613 JkH1 M �emlt Axiom Environmental, Inc. P1 VUUAM January 2014 [91 GUINLY&I OJIu/\:7'/ 1�1 7T 1 The Goose Creek stream restoration project originated by the North Carolina Ecosystem Enhancement Program (EEP) was constructed between May 12, 2008 and September 5, 2008. Grading and stream structure installation began on May 14, 2008 and was completed on August 20, 2008. Planting of the buffer was completed on February 18, 2009. The Goose Creek Stream Restoration Site (Site) is located in the City of Durham, North Carolina in a highly developed watershed (Figure 1, Appendix A). Goose Creek is part of the Neuse River Basin (Upper Neuse, Subbasin 03- 04 -01) and is located in USGS Cataloging Unit 03020201. This project is located in the EEP's Ellerbe Creek Local Watershed Plan (http: / /www.nceep. net / services /lwps/Upper_Neuse /Ellerbe Creek_Local_Watershed_Plan.pdf) area, which is targeted for mitigation to protect watershed functions, increase aquatic life, decrease destructive flooding, provide recreational opportunities, and protect the Falls Lake drinking water supply. The preproject stream was highly modified and artificially confined by concrete along the southern/upstream channel and banks, and by rock walls in the northern/downstream reach. The project aimed to eradicate artificial hardening structures, and restore a more natural channel geometry and riparian buffer. Project restoration efforts provided 1465 linear feet of stream restoration, 1.38 acres of riparian buffer restoration, and 0.06 acre of riparian buffer enhancement. Tables summarizing project objectives and activities can be found in Appendix A. This report (compiled based on the EEP's Procedural Guidance and Content Requirements for EEP Monitoring Reports Version 1.4 dated 11/7/11) summarizes data for year 5 (2013) monitoring. The goals of the Goose Creek stream restoration project included the following. • To improve aquatic habitat by removing the fabriform channel liner on the Eastway Elementary School reach (upstream/southern reach) and the stone retaining walls on the Longmeadow Park reach (downstream/northern reach) and reintroduce a more defined and natural riffle /pool channel geometry. • To improve water quality by reducing nutrient loading from adjacent developed properties through restoration of a riparian buffer. • To improve terrestrial habitat by restoring a riparian buffer. • To decrease the sediment and nutrient content of stormwater flow originating in the Barnes Street Redevelopment project site, which flows through the Site and into Goose Creek, through the means of a re- configured stormwater channel which slows stormwater flow, allowing sediment to settle and nutrients to be absorbed by planted vegetation. Goals were accomplished by removing artificial hardening structures; constructing a natural, stable profile and dimension for the stream channel; and reestablishing a continuous riparian buffer along the stream banks. Project implementation has greatly increased the prominence of riffles and pools in the reach and improved aquatic habitat within the Site. Based on the Goose Creek baseline document (2009), success criteria dictate that after five monitoring years an average density of 260 stems per acre must be surviving in stream restoration areas (Vegetation Plot 4) and 320 stems per acre must be surviving in Neuse River Riparian Buffer restoration credit areas (Vegetation Plots 1, 2, and 3). Based on the number of stems counted, average densities were measured at 485 planted stems per acre (excluding livestakes) surviving in year 5 (2013). The dominant species identified at the Site were planted stems of green ash (Fraxinus pennsylvanica), tulip tree (Liriodendron Goose Creek (final) Axiom Environmental, Inc. Monitoring Year 5 of 5 (2013) EEP Project Number 147 January 2014 Durham County, North Carolina page i tulipifera), and sycamore (Platanus occidentalis). All individual plots met success criteria based on planted stems alone. Three large willow oaks (Quercus phellos) (located on the downstream/northem reach) that had succumbed to the stress of old age and drought were removed by the City of Durham in the winter of 2011 with the approval of EEP. Planting within these areas as well four additional areas on the upstream/southern reach) were planted with 70 five- gallon sized containerized trees of red oak (Quercus rubra), sycamore, red chokeberry (Aronia arbutifolia), red maple (Acer rubrum), cherrybark oak (Quercus pagoda), and Shumard oak (Quercus shumardii), in addition to 25 livestakes of silky dogwood (Cornus amomum). Trees within these areas are doing well; 2012 planting information is provided in Appendix F. Noted vegetation areas of concern within the Site, depicted on the attached Figures 2A -2B (Appendix B), include the development of invasive species such as Johnson grass (Sorghum halepense) scattered along the northern/downstream reach between Liberty Street and Holloway Street. Other invasive species include small patches of Japanese hops (Humulus japonicas) just north of the Liberty Street bridge on the right bank and adjacent to the left bank of the western tributary to the southern/upstream reach. Mimosa (Albizia julibrissin), chinaberry (Melia azedarach), and white mulberry (Morus alba), are located in several locations along the northern (downstream reach). Chinese privet (Ligustrum sinense) and Japanese privet (Ligustrum japonicum) are located just north of the stormwater wetland and adjacent to the fence just south of the tributary to the southern/upstream reach coming from the west. Scotch broom (Cytisus scoparius) is located at the very southeastern corner of the Site; some treatment /control of this species occurred in the 2011 monitoring year by cutting plants to remove the seed source. In addition, scattered stems of Bradford pear (Pyrus calleryana), white mulberry, wintercreeper (Euonymous fortunei), air yam (Discorea bulbifera), and multiflora rose (Rosa multiflora) are located adjacent to the southern/upstream reach. Herbaceous species including Nepalese browntop (Microstegium vimineum) and Asiatic dayflower (Commelina communis) are also located in several areas along the southern/upstream reach near the stream channel. Invasive species within the Site are not affecting planted stem survival or growth, and are therefore expected to be shaded out as planted trees mature. Wisteria (Wisteria frutescens) is located just north of Liberty Street on the right bank adjacent to the bridge and giant ragweed (Ambrosia trifida) is scattered throughout the Site and occasionally forms thick stands. Wisteria and giant ragweed are not invasive species but can be problematic due to their growth habits and potential to shade or, in the case of wisteria, girdle planted trees. These species have been monitored closely throughout the monitoring period and are not affecting growth of planted stems. Success criteria for stream restoration reaches dictate that little to no change from the as -built channel occurred over the five -year monitoring period. Year 5 (2013) monitoring measurements indicate that there have been minimal changes in cross - sections and profile downstream of Liberty Street as compared to as -built data. The stream profile upstream of Liberty Street was designed to adjust itself to changes in watershed flows. A total of 16 bankfull events are documented to have occurred at the Site with three events in year 1 (2009), three events in year 2 (2010), three events in year 3 (2011), and four events in the year 4 (2012), and three events to date in year 5 (2013) monitoring period. Two structures (upstream of Cross - section 5 and downstream of Cross - section 6) that were watched throughout the five -year monitoring period due to boulders that had fallen in the channel are doing well and are not exhibiting additional erosion despite extensive flooding during the 2013 monitoring year. The upper reach of Goose Creek was an unconventional design, which allowed for the evolution of a low flow channel within the larger bankfull channel. Single wing deflectors were installed to increase channel Goose Creek (final) Axiom Environmental, Inc. Monitoring Year 5 of 5 (2013) EEP Project Number 147 January 2014 Durham County, North Carolina page ii sinuosity (restricted due to a narrow beltwidth) within the larger bankfull channel, allowing the thalweg to migrate within the bankfull channel. Dense, rooted vegetation has established throughout the reach and adjacent to the structures inhibiting lateral erosion and bed scour. The structures and the entire reach are stable and functioning as designed, and have remained intact despite flashy flows from the upstream watershed, which is primarily comprised of impervious surfaces associated with the City of Durham, and several large rainfall events (Tropical Storm Ida and numerous rain events of greater than 4 inches) that have occurred throughout the five -year monitoring period. In summary, the Site achieved success criteria for vegetation and stream attributes in the Fifth Monitoring Year (2013). 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 tables 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.

Sampling was conducted for year 5 (2013) on September 10, 2013 as outlined in the CVS -EEP Protocol for Recording Vegetation, Version 4.2 (Lee et al. 2008) ( http :Hcvs.bio.unc.edu/methods.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 Figures 2A -2B in Appendix B. Visual assessments were completed on September 10, 2013 for year 5 (2013). 2.2 Stream Assessment Eight 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. Longitudinal profile measurements of the entire Site restoration reaches include thalweg and water surface; with each measurement taken at the head of facets (i.e. riffle, run, pool, and glide) in addition to the maximum pool depth. Visual assessments of in- stream structures were conducted to determine if failure occurred. Failure of a structure may be indicated by collapse of the structure, undermining of the structure, abandonment of the channel around the structure, and/or stream flow beneath the structure. Stream measurements were completed the week of April 8, 2013 (Appendix D). 3.0 REFERENCES Lee, Michael T., R.K. Peet, S.D. Roberts, and T.R. Wentworth. 2008.

In the event a polygon is cataloged into items 1, 2 or 3 in the table and is the result of encroachment, the associated acreage should be tallied in the relevant item (i.e., item 1,2 or 3) as well as a parallel tally in item 5. 4 = Invasives may occur in or out of planted areas, but still within the easement and will therefore be calculated against the overall easement acreage. Invasives of concern /interest are listed below. The list of high concern spcies are those with the potential to directly outcompete native, young, woody stems in the short-term (e.g. monitoring period or shortly thereafter) or affect the community structure for existing, more established tree /shrub stands over timeframes that are slightly longer (e.g. 1 -2 decades). The low /moderate concern group are those species that generally do not have this capacity over the timeframes discussed and therefore are not expected to be mapped with regularity, but can be mapped, if in the judgement of the observer their coverage, density or distribution is suppressing the viability, density, or growth of planted woody stems. Decisions as to whether remediation will be needed are based on the integration of risk factors by EEP such as species present, their coverage, distribution relative to native biomass, and the practicality of treatment. For example, even modest amounts of Kudzu or Japanese Knotweed early in the projects history will warrant control, but potentially large coverages of Microstegium in the herb layer will not likley trigger control because of the limited capacities to impact tree /shrub layers within the timeframes discussed and the potential impacts of treating extensive amounts of ground cover. Those species with the "watch list" designator in gray shade are of interest as well, but have yet to be observed across the state with any frequency. Those in red italics are of particular interest given their extreme risk/threat level for mapping as points where isolated specimens are found, particularly ealry in a projects monitoring history. However, areas of discreet, dense patches will of course be mapped as polygons. The symbology scheme below was one that was found to be helpful for symbolzing invasives polygons, particulalry for situations where the conditon for an area is somewhere between isolated specimens and dense, discreet patches. In any case, the point or polygon /area feature can be symbolized to describe things like high or low concern and species can be listed as a map inset, in legend items if the number of species are limited or in the narrative section of the executive summary. °% of Mapping CCPV Number of Combined Easement Vegetation Category Definitions Threshold Depiction Polygons Acreage Acreage Johnson grass is scattered along the northern /downstream reach etween Liberty Street and Holloway Street; however, it does not appear to be affecting planted tree stems.
