The objective of this project is to provide stream mitigation units (SMU) and wetland mitigation units (WMU) to the PTAA to offset impacts in the Cape Fear 03030002 hydrologic unit. The mitigation units required are being accomplished through the restoration of stream ' and wetland riparian habitats at the above referenced sites as specified in USACE Permit Number 200021655 and DWQ Permit Number 00-0846. ' The construction of the wetlands at BC-I, BC-II and BC-III was completed in January and February 2008. The restoration of the stream at BC-III was completed in February 2009. The project was designed by ECS Carolinas, LLP and constructed by Shamrock Environmental. An erosion control berm remains around portions of BC-II. The berm in BC-II is scheduled for removal in January 2010, weather permitting. The removal of the berm has been approved by the North Carolina Department of Environment and Natural Resources, Division of Land Quality. This monitoring report includes the second year of monitoring for the wetlands and ' the first year of monitoring for the stream at BC-I II. As-built drawings for BC-II are awaiting submittal pending the removal of the erosion control t berm. Due to conditions encountered during construction, the size and extent of wetlands were altered as necessary. The following alterations were made: • BC I - Based on the design/permit the restored wetlands in BC I were sch d l d t b , e u e o e 4.66 acres in area. The actual amount of wetlands as surveyed following construction is 4.54 acres. • BC II - Based on the permit, the created wetlands in BC II were scheduled to be 5 3 . acres in area. After the berm is removed, the actual amount of wetlands is anticipated to be 9.0 acres in area (less 0.6 acres for USACE Action ID # SAW200641354241 and DWQ # 00- 1632). • BC III - Based on the design/permit the restored wetlands in BC III w h d l d , ere sc e u e to be 2.7 acres in area. The actual amount of wetlands as surveyed following construction is 2.06 acres. • BC III - Based on the permit, 200 linear feet of stream were to be restored. The actual ' amount of stream restored as surveyed following construction is 450 linear feet. Based on the permit, the overall mitigation compliance for BC I, II and III included the restoration of 7.4 acres of wetland, the creation of 5.3 acres of wetland and the restoration of 2 00 linear feet of stream. As determined by the survey following construction, 6.60 acres of wetland and 450 linear feet of stream have been restored. Based on preliminary estimates , 9.0 acres of wetland have been created. t 1 I ECS Carolinas, LLP 2 1 u: -Y l 'All 00, I Scale: 1" = 800' Figure 1: 2007 Aerial Photograph from Guilford County GIS Data Viewer BC-1 is located to the south of North Triad Boulevard near its intersection with Airport Parkway. BC-1 is a restored wetland that includes two cells that contain approximately 4.54 acres. The two wetland cells are bisected by an unnamed tributary to Brush Creek. ECS Carolinas, LLP 3 BRUSH CREEK STREAM AND WETLAND MITIGATION PROJECT MONITORING REPORT ECS PROJECT No. 09-12666D BC-II is located to the southeast of Airport Parkway. BC-11 is a created wetland that is approximately 9.0 acres in area. ' BC-III is located to the southeast of the new alignment of Airport Parkway (not shown on Figure 1). BC-III is situated in the former roadway of Old Oak Ridge and consists of ' approximately 2.06 acres of restored wetland and approximately 450 linear feet of restored stream channel. This report documents the monitoring of the completed Brush Creek wetland mitigation areas.

Year one monitoring was completed for the restored stream at BC-III. The monitoring was performed between September and November 2009. Hydrology was monitored throughout 2009. The data analyzed includes stream channel cross sections (Appendix B) and stream channel profiles (Appendix C) with a virtual reference station (VRS), pebble counts (Appendix D) with a gravelometer, photographs (Appendix E) taken with a digital camera, monitoring well data (Appendix F) collected from pre-established wells, and vegetation counts (Appendix G) in pre- established plots and transects. Observations of structures, vegetation and problem areas were made throughout the data collection process and are documented in this report. MONITORING RESULTS The stream profile and cross sections were surveyed at BC-III. Graphs depicting the survey results of stream channel cross sections are included in Appendix B and stream channel profiles are included in Appendix C. The results of the surveying do not reveal significant changes from the as-built surveys. The survey data indicates stable cross sections with no significant widening or increases in depth. However, based on visual observations, repairs to Cross Vane 1 and Cross Vane 2 are needed. In addition, repairs are needed on the left bank (when facing downstream) at the lower end of the stream at BC-III. These areas have been scheduled for repair. Based on a comparison of the as-built data, there has been little to no change in the streambed material in the riffle and pool sequences. Graphs of pebble counts at each of the cross sections are included in Appendix D. Monitoring well data indicates that hydrology is present at levels above the monitoring success requirements in 12 out of 14 monitoring wells that are located in the three wetland areas. MW 3 in BC-II and MW 2 in BC-III were slightly below monitoring success requirements. Graphs showing water levels in each of the wetland monitoring wells are included in Appendix F. Based on vegetative sampling, BC-I, BC-II and BC-III are each within the success range for vegetative criteria. Additional planting in 2010 is not recommended. Wetland vegetation and live staking stem count data is included in Appendix G. ECS Carolinas, LLP 5 BRUSH CREEK STREAM AND WETLAND MITIGATION PROJECT MONITORING REPORT ECS PROJECT No. 09-12666D RESTORATION SUCCESS CRITERIA STREAM DIMENSION Cross section data was collected at established monitoring locations using a geophysical virtual reference system (VRS). Two cross sections were analyzed using Microsoft Excel software and compared to as-built data. Graphs of the resulting data are included in Appendix B. The cross sectional dimensions of the streams are consistant with the as-built data. The data does not reveal significant widening or increases in depth. The following visual observations were noted during recent site visits. The left arm of Cross Vane 1 and the right arm of Cross Vane 2 have collapsed into the stream. The stream bank above the vane arms are matted and live staked. Therefore, severe bank erosion has not occurred as a result of the collapsed vane arms. The vane arms are scheduled for repairs. Bank erosion has occurred on the left bank at the lower reaches of BC-III. Repairs are scheduled to correct this portion of the stream. STREAM PATTERN AND PROFILE 1 Stream pattern and profile data was collected for the entire length of all reaches using a geophysical VRS. Data collected included thalweg inverts of in-stream structures water , , surface, and low top of bank. This data was analyzed using Microsoft Excel software and compared to as-built data. This data is presented in graphs located in Appendix C. Changes ' were not observed in the thalweg depth or in the stream pattern. Elevation and slope of the riffle and pool sections are consistent with previous monitoring data. STREAM BED MATERIAL ANALYSIS Stream bed material anal sis was co l t d f ll h h y mp e e or a reac es at eac permanent cross section. A gravelometer was used to determine pebble size. Based on a comparison of the as-built data, there has been little to no change in the streambed material in the riffle and pool sequences. Graphs of pebble counts at each of the cross sections are included in Appendix D. PHOTOGRAPH REFERENCE SITES Photographs were taken using a digital camera and these photographs are documented in the Photo Log in Appendix B. The wetland photographs were taken in September. The stream photographs were taken in December. The photograph locations are identified in the photo logs and the site plans in Appendix A. WETLAND HYDROLOGY Wetland hydrology has been analyzed using monitoring wells with data loggers. Several monitoring wells were installed in each of the wetlands. The locations of monitoring wells are identified on the site plans (Appendix A). Data loggers gather water level readings at 7:00 AM each day. The information from the wells is downloaded monthly, and the resulting data has been analyzed using Microsoft Excel software to determine the average depth to groundwater. The graphs depicting this analysis are located in Appendix C. Twelve of the fourteen wetland monitoring wells met the wetland success criteria during 2009. One monitoring well located in BC-II (MW 3) and one monitoring well located in BC-III (MW 2) did not meet the criteria. BC-II, MW 3 did not meet the criteria of staying inundated for 28 consecutive days during the growing season. However, BC-II, MW 2 stayed inundated within the upper 12 inches for 67 days out of the 226 days of the growing season. BC-III, MW 2 ECS Carolinas, LLP 6 BRUSH CREEK STREAM AND WETLAND MITIGATION PR03ECT MONITORING REPORT ECS PRO3Ecr No. 09-12666D stayed inundated within the upper 12 inches for a total of 46 days throughout the growing season. Based on local weather data (NOAA.gov), the 2009 growing season (March through November) in this area of North Carolina was under "abnormally dry" to "moderate drought" conditions from July to November. During a year with normal precipitation, it is possible that each of the wells would meet the wetland hydrology success criteria. BANKFULL EVENTS 1 Several bankfull events have occurred since construction. Photographs documenting bankfull events that occurred in 2009 are included in Appendix E. 1 1 1 1 D 1 1 ECS Carolinas, LLP 7 BRUSH CREEK STREAM AND WETLAND MITIGATION PROJECT MONITORING REPORT ECS PROJECT No. 09-12666D VEGETATIVE PLANTING Vegetation sampling plots were established at the restoration site to monitor the success of wetland vegetation. The locations of these plots were random but distributed across the planted portions of the site (see photos in Appendix B). A Riparian Buffer Transect along the stream at BC-III was sampled to identify vegetative success in the streamside vegetation zones. The data resulting from the sampling of both the vegetative plots and buffer transect can be found in Appendix G. Based on the sampling, BC-l, BC-11 and BC-III are within the success range for vegetative criteria. Tables 1, 2 and 3 show the current wetland stocking levels. Table 1.

ECS Carolinas, LLP 8 BRUSH CREEK STREAM AND WETLAND MITIGATION PROJECT MONITORING REPORT ECS PROJECT No. 09-12666D BENTHIC MACROINVERTEBRATE SAMPLING Benthic macro-invertebrates sampling is not required for this site and sampling was not conducted. 1 WILDLIFE OBSERVATIONS During the various monitoring events, ECS observed the site for wildlife. ECS has observed the following wildlife species or evidence of the following wildlife species on the site: Mallard Ducks; Canada Geese; Blue Herons; Various Songbirds; Whitetail Deer; 1 Minnows; and Frogs. 1 1 1 ECS Carolinas, LLP 9 1 1 n u MAINTENANCE AND CONTINGENCY PLANS NEW DEVELOPMENT BRUSH CREEK STREAM AND WETLAND MITIGATION PROJECT MONITORING REPORT ECS PROJECT No. 09-12666D At the end of the second year of monitoring, herbaceous wetland vegetation is prevalent throughout the wetlands in BC-I, BC-II and BC-III. Areas of the wetlands that were bare during the first year of monitoring are now vegetated. The woody vegetation requirements have been met for the second year of monitoring. No additional planting is recommended at this time. Planting in BC-11 is scheduled following the removal of the erosion control berm. The areas disturbed during berm removal will be reseeded and mulched in accordance with the specifications of the Brush Creek Wetland Mitigation Plan. Twelve of the fourteen wetland monitoring wells met the wetland success criteria during 2009. One monitoring well located in BC-11 (MW 3) and one monitoring well located in BC-III (MW 2) did not meet the criteria. However, BC-II, MW 2 stayed inundated within the upper 12 inches for 67 days out of the 226 days of the growing season. BC-III, MW 2 stayed inundated within the upper 12 inches for a total of 46 days throughout the growing season. The 2009 growing season (March through November) in this area of North Carolina was under "abnormally dry" to "moderate drought" conditions from July to November (NOAA.gov). During a year with normal precipitation, it is possible that each of the wells would meet the wetland hydrology success criteria. As-built drawings have been submitted for BC-I and BC-III. As-built drawings for BC-11 will be submitted after removal of the erosion control berm. The wetland area in BC-11 has been estimated based on GPS measurements and is subject to change with the completion of the as-built survey. At the end of the first year of monitoring of the stream at BC-III, repairs are required for two cross-vane arms and an eroded area on the left bank on the lower reach of the stream. The footer rocks of the two vane arms were undercut initially during grading and further by heavy stream flow. These items can be corrected with routine repairs. Scheduled repairs are discussed below. STREAM MAINTENANCE AND RECOMMENDATIONS Corrective actions are needed for two cross-vane arms located in the stream at BC-111 and the left bank on the lower reach of BC-III. The cross vane arms and bank are scheduled for repairs. It appears that the initial failure of the two vane arms was caused by undercutting the footer rocks during the grading process and further by stream flow. To repair the vane arms, suitable footing material consisting of a well graded mixture of stone will be added so that the footer rocks are not undercut in the future. Any areas disturbed during the repairs are to be reseeded, mulched, matted and livestaked. The left bank at the lower end of BC-III will be regraded to a 3:1 to 5:1 slope. All disturbed areas will be reseeded, mulched, matted and livestaked. An outlet for a nearby culvert will be regraded and covered with a stone dissipater to further improve the conditions of the bank in this area. WETLAND MAINTENANCE AND RECOMMENDATIONS No wetland maintenance is recommended at this time. Nuisance species such as cattail (Typha latifolia) have been observed in localized areas in each of the wetlands. They do not appear to be creating a monoculture in any of the areas and no maintenance is recommended at this time. However, they should be monitored closely to ensure that a monoculture does not develop. 0 ECS Carolinas, LLP 10 BRUSH CREEK STREAM AND WETLAND MITIGATION PROJECT MONITORING REPORT ECS PROJEcr No. 09-12666D COMMENTS AND OBSERVATIONS At the end of the second annual monitoring period for the wetlands in BC-I, BC-II and BC-III, the majority of the wetlands have met the hydrology and vegetative success requirements. No repairs or maintenance are recommended at this time. At the end of the first year of monitoring the stream at BC-III, repairs are needed to portions of the stream. These repairs have been scheduled and will be implemented as soon as the weather permits.
