and Backimound Summa The Cutawhiskie Creek Restoration Site (hereafter referred to as the "Site ") was constructed for the North Carolina Ecosystem Enhancement Program (NCEEP) to provide compensatory stream and wetland mitigation in the Chowan River Basin This restoration project is located on an unnamed tributary (UT) to Cutawhiskie Creek on a 22 9 acre Site located in Hertford County The project includes stream restoration (Priority 1) and preservation, as well as riparian wetland restoration and enhancement Cutawhiskie Creek and the UT were dredged in the mid -1960s in accordance with historic agricultural /silvicultural management practices Impacts resulting from stream alteration include bank erosion, channel incision, and loss of characteristic riffle /pool complex morphology Natural vegetation within adjacent areas, including stream buffers zones, was removed throughout much of the Site The floodplam was impacted by deforestation and groundwater draw -down from stream channel dredging activities A significant increase in nutrient and sediment loading has resulted from these Site modifications, and adjacent wildlife habitats have been eliminated or fragmented The primary restoration features within the Site include the UT and approximately 13 acres of drained hydric sods within degraded wetlands The UT has been dredged and straightened, such that it no longer retained stable dimension, pattern, and profile The presence of hydnc sods indicates that riparian wetlands were adjacent to Cutawhiskie Creek and the UT prior to anthropogenie channel impacts Channel alteration had resulted in hydrologic modifications that effectively drained most of the adjacent wetlands Site restoration activities included the excavation of a new stream channel, floodplam excavation, removal of stumps and debris, existing channel backfillmg and onsite drainage ditch removal, and final grading and sod preparation within the adjacent floodplam These activities were to reintroduce surface water flood hydrodynamics from a 0 9 -square mile watershed along the newly restored length of stream and floodplam The new channel was constructed to reflect regional stream characteristics and accommodate bankfull flows Characteristic wetland sod features, groundwater wetland hydrology, and hydrophyhc vegetation communities are developed in areas adjacent to the constructed channel Wetland and adjacent slope sod surfaces were restored and the Site reforested to riparian and upland slope hardwood communities Plant community associations were designed to mimic various communities described by Schafale and Weakley (1990), including Coastal Plain Levee Forest, Cypress -Gum Swamp, Mesic—Mixed Hardwood Forest, and Coastal Plain Small Stream Swamp Goals and Obiectrves Site restoration activities included the excavation of a new stream channel, limited floodplam excavation, removal of stumps and debris, existing channel backfillmg, on -site drainage ditch removal, and final grading and soil preparation within the adjacent floodplam These activities were proposed in order to reintroduce surface water flood hydrodynammcs from a 0 9 -square mile watershed along the newly restored length of stream and floodplam The new channel was constructed to reflect regional stream characteristics and accommodate bankfull flows Characteristic wetland sod features, groundwater wetland hydrology, and hydrophytic vegetation communities are expected develop in areas adjacent to the constructed channel Wetland and adjacent slope sod surfaces were restored and the Site reforested to promote riparian and upland slope hardwood communities Plant community associations were designed to mimic various indigenous communities described by Schafale and Weakley (1990), including Coastal Plain Levee Forest, Cypress -Gum Swamp, Mesic —Mixed Hardwood Forest, and Coastal Plain Small Stream Swamp Specific ecological benefits anticipated as a result of on -Site restoration activities are as follows • Stream channel restoration will reintroduce stable bankfull dimension, pattern, and profile along restored stream reaches, which is expected to enhance lotic habitat quality and stream function • Floodplam excavation adjacent to restored streams will restore the characteristic flood regime, as well as provide a lateral hydrologic input to restored wetland areas adjacent to the UT and within the greater Cutawhiskie Creek floodplam • Restored and enhanced wetland areas will help to improve water quality via nutrient removal, increase local vegetative biodiversity, provide wildlife habitat, and serve as a forested corridor, linking the Site with adjacent forested areas Page 2 of 17 Success Criteria Stream Channel To ensure stable bankfull dimension, pattern, and profile along the restored channel, annual stream assessment surveys will be undertaken A longitudinal profile survey along the entirety of the UT has been established to verify stream profile stability Six stream channel cross - sections have also been established to monitor any potential instability and adverse changes in channel geometry Measured parameters for future monitoring work will include cross - sectional area, bankfull width, average and maximum bankfull depth, width -to -depth ratio, and substrate size class distribution Longitudinal profiles and cross - sections will be surveyed annually throughout the 5 -year project monitoring period Channel geomorphic data will be analyzed and presented in the Site's Annual Monitoring Reports Success criteria for stream restoration and Level 1 enhancement will include 1) successful classification of the reach as a functioning system (Rosgen 1996), and 2) channel stability indicative of a stable stream system Photo points have been established in conjunction with channel cross - sections to further document stability Additional photo points may be added so that any potential areas of instability will be documented and addressed with remedial maintenance measures Groundwater Hydrology Five (5) auto - logging groundwater monitoring gauges have been installed in wetland restoration areas for monitoring gauge locations) Gauges will be downloaded monthly throughout the growing season Hydrologic success criteria will be achieved by registering groundwater levels within the upper 12 inches of the soil surface for a minimum number of consecutive days corresponding to at least 12 5 percent of the growing season in Hertford County under normal annual precipitation Exceptions will be made if monitoring gauges do not achieve success criteria during documented Site drought conditions Target hydrological characteristics include saturation or inundation for a minimum of 12 5 percent of the growing season during average climatic conditions In some instances, the regulatory wetland hydroperiod may include areas that are saturated between 5 and 12 5 percent of the growing season If wetland parameters are marginal as indicated by vegetation and hydrology monitoring, ajurisdictional determination will be performed in the questionable areas Vegetation Vegetation monitoring (10 X 1 Om2) plots have been established to monitor planted vegetation within Site restoration and enhancement areas Site vegetation will be monitored in accordance with the guidelines and procedures developed by the Carolina Vegetation Survey (CVS) (CVS -EEP Protocol for Recording Vegetation, Level 1 -2 Plot Sampling Only, Version 4 0, 2006) Established vegetation monitoring plot locations are displayed on Figures 3A -B (Appendix A) Plots will be monitored annually, and a stem count of planted species as well as an assessment of survivability of planted stems will be performed Vegetative monitoring success will be achieved by plot data indicating an average number of planted stems per acre exceeding 320 stems /acre after the third year of monitoring and 260 stems /acre after the fifth and final year of project monitoring If vegetation success criteria are not achieved for the planted stem/acre density calculations from combined sample plot data, supplemental plantings will be performed with native tree species approved by the appropriate regulatory agencies (i e , EEP, United States Army Corps of Engineers, and North Carolina Division of Water Quality) Supplemental plantings will be performed as needed until vegetative success criteria are achieved Page 3of17 MITIGATION UNIT TOTALS Stream Mitigation Units Restoration Segment/Reach Pre — Construction (acreage
