The site is located in Greensboro, Guilford County, North Carolina. The site was originally designed and constructed in 1999 by the North Carolina Department of Transportation (NCDOT). Portions of the mitigation site were repaired in Winter 2005/2006. This report provides the monitoring results for the 2006 monitoring year for the entire restoration site. The Starmount Forest Site was constructed to provide 7,950 linear feet of mitigation credit for stream impacts associated with NCDOT impacts. Per the letter from the Ecosystem Enhancement Program (EEP) to NCDOT dated August 25, 2004, the EEP has accepted the transfer of all offsite mitigation projects; including Starmount Forest. The EEP project number for Starmount Forest is 360. EEP is responsible for fulfilling the remaining monitoring requirements and future remediation for this project. No hydrologic or vegetation monitoring is required for this project; however, a visual assessment of vegetative cover and stream stability was performed in spring 2006 and fall 2006. All restoration reaches appeared stable with herbaceous and woody vegetation covering the stream banks throughout. Vegetative cover was extensive throughout including the repaired areas. Some minor areas of erosion are present but do not present a problem to stream stability. One area of bank erosion on Thread D will require remedial action. Page 1 Starmount Forest Mitigation Site, EEP Project No. 360 WK Dickson, January 2007 Final 2006 Monitoring Report 1.0 INTRODUCTION: STARMOUNT FOREST MITIGATION SITE 1.1 Project Description The Starmount Forest Mitigation Site is located in Greensboro on Starmount Forest Country Club golf course. The site is located on the northwest corner of the intersection of Holden Road and West Market Street (Figure 1). The site provides 7,950 linear feet of stream restoration credit. 1.2 Project Purpose The purpose of this report is to detail the vegetation and stream assessment in 2006 at the Starmount Forest Mitigation Site. No quantitative vegetation or stream survey is required at this site. 1.3 Project History The following tables summarize project mitigation structure and objectives, project history, project contacts, and project background (Tables I-IV). Much of the information needed to complete the tables was not available when this report was submitted. Table I.

Starmount Forest Planted Snecies Common Name Scientific Name Silk dogwood Corntts amomum Black chokeberry Aroma melanocarpa Red chokeberry Aronia arbuti olia Lowbush blueberry Vaccinium an usti olium Witch hazel Hamamelis vir iniana River birch Betula ni ra Green ash Fraxinus enns lvanica Red maple Acer rubrum Americansycamore Platanus occidentalis Flowering dogwood Cornus orida 2.2 Results of Vegetation Assessment The Starmount Forest site was visited in Spring 2006 and Fall 2006 to visually assess vegetation. Starmount Forest Country Club is an intensively maintained landscape for purposes of golf play. The planted vegetation and live stakes appeared to be present in sufficient density to provide stability, habitat, and aesthetics. Golf course maintenance has not impacted vegetative cover beyond approved maintenance areas. The repair areas on threads B and D were stable and the temporary seeding and live stakes were in good shape. Other species noted: soft rush (Juncus effusus), turf grasses, Japanese honeysuckle, and jewel weed (Impatiens capensis). 2.3 Vegetation Conclusions This site consists of a narrow riparian zone planted with a combination of low growing vegetation in golf play areas and woody vegetation in other areas. The 2006 vegetation assessment revealed all planted vegetation is sufficiently dense and stable and no remedial actions are warranted. Page 6 Starmount Forest Mitigation Site, EEP Project No. 360 WK Dickson, January 2007 Final 2006 Monitoring Report 3.0 STREAM: STARMOUNT FOREST MITIGATION SITE The Starmount Forest stream channel threads A-E were visually inspected during the spring and fall of 2006. The channel was walked and compared to the construction plans. The pedestrian survey included inspection for: • structure failure • bank erosion • head cuts, • aggradation • other potential impacts to stability. The channel appears stable with herbaceous and woody vegetation covering the stream banks throughout the project reach. Some minor erosion was observed (Photos in Appendix A). Special attention will be paid to these areas during subsequent monitoring in 2007. Particular attention was paid to the repair areas on Thread B (169 linear feet) and Thread D (314 linear feet). Thread B is stable and well vegetated. The repairs appear successful and no further remedial actions are needed. Thread D contains one area of bank erosion that will need repair in the future. This problem area is discussed in more detail in Appendix B. Overall the channel had excellent habitat diversity, well developed undercut banks, and coarse bed material. As previously stated, no cross section or profile survey of this site is required.
