STREAM MITIGATION PLAN CAROLINA GOLF CLUB MECKLENBURG COUNTY, NORTH CAROLINA 1.0 INTRODUCTION This document summarizes stream mitigation activities to be performed at the Carolina Golf Club, located in downtown Charlotte, North Carolina (Figure 1). The project will provide compensatory mitigation for stream impacts associated with construction of an impoundment, primarily for irrigation and course habitat purposes, within this heavily urbanized landscape. This concept plan is intended to facilitate issuance of a US Army Corps of Engineers (USAGE) individual permit for the golf course improvements. The plan provides a description of stream restoration, enhancement, and preservation activities along with a vegetation planting plan, monitoring plan, success criteria, and final disposition /management of the conservation areas. Detailed stream design and technical specifications will be finalized after further reference stream studies and golf course renovation activities. The mitigation includes approximately 2091 feet of stream restoration and enhancement and approximately 1000 feet of stream preservation as depicted in Figure 2. In addition, approximately 5.30 acres of riparian buffers will be established along the stream mitigation corridors. The mitigation is contained on-site within the golf course and encompasses areas surrounding the proposed impoundment. The streams have been identified as Reach 1, 2, 3, 6, 7, and 8 and range from former streams currently buried within pipes and culverts to impounded sections that do not support viable riparian buffers or stream-side communities (Figure 3). Land manipulations such as clearing of riparian vegetation, relocation, dredging, straightening, and culverting of the streams has resulted in habitat loss, water quality concerns, and unstable stream and riparian characteristics. In this urbanized landscape, the primary objectives of this mitigation effort include the following: 1. Elevate and re-connect these stream channels and overbank flows to active floodplains within the conservation areas. 2. Encourage wetland habitat and vegetation roughness within the stream channels and on the restored floodplains to provide detention and to attenuate storm runoff into downstream waters. 3. Establish in-stream and floodplain habitat for urban wetland species, including those that assist in controlling mosquito populations (ex: tadpoles, toads, anoles, small mammals, purple martin, waterfowl, etc.). 4. Restore and manage the conservation buffers for dense, herb, shrub and understory dominated wetland species (for maximum vegetation roughness and golf course line- of-sight requirements). 5. Prevent broadcast fertilizer, pesticides, or other chemicals from entering the conservation buffers, the stream, and downstream waters. 6. Reestablish stream stability and the capacity to transport watershed flows and attenuate sediment loads by restoring stable dimension, pattern, and profile supported by natural in-stream habitat. 7. Improve aquatic habitat by removing culverts and enhancing stream bed variability through the use of in-stream structures. 8. Provide wetland and wildlife habitat within buffers previously developed for urban land uses. 9. Protect the streams and buffers in perpetuity with restrictive covenants.

This hydrophysiographic region is underlain by the metamorphosed granitic rocks characterized by moderately dissected, irregular plains with low to moderate gradient streams (Griffith 2002). This region is characterized by moderately high rainfall with precipitation averaging approximately 43 inches per year. This hydrophysiographic region extends over a broad portion of the central North Carolina Piedmont from Greensboro to the east and west to the base of the Blue Ridge Province. Reference stream attributes, used to guide the stream mitigation design, will be further developed within the targeted hydrophysiographic region for this project. Approximate watershed areas are depicted in Figure 2 and range from 0.18 to 0.51 square miles in size. Excluding the golf course area, the watersheds are heavily urban in character. Impervious surfaces are expected to account for more than 50% of the land surface area. Based on topographic mapping developed for this project (Figure 3), valley slopes range from 0.036 (3.6%) along the upstream periphery of Reach 1 to 0.009 (0.9%) within downstream limits of the project. Stream channels are dominated by sand, silt, and small gravel beds in upper watershed reaches to coarse sand, larger gravel, and small cobble dominated beds in larger streams in the area. Figure 4 and Figure 5 depict the approximate stream alignments and the proposed riparian buffers. The 6 project reaches encompass 3091 linear feet of stream channel and 5.3 acres of buffer restoration and management land. Detailed design parameters will be developed after additional reference studies and golf course renovation activities Are completed. Reference Studies and Functional Evaluations A fundamental concept of stream mitigation involves the study of reference (relatively undisturbed) streams and vegetation within the ecoregion as part of detailed planning. Subsequently, measurement and analyses of existing and proposed conditions can be performed. This method for stream mitigation ensures that the preferred ecosystem processes and functions can be restored. This method ensures that form or shape of the stream channel is not the most important design consideration for this project. Therefore, final design parameters, based upon preferred riparian ecosystem functions, will be established in the Fall of 2007 once reference studies have been completed and golf course renovation activities are underway. Regional reference curves will be utilized to predict bankfull stream geometry, discharge, and other parameters in the altered systems. Development of regional reference curves for North Carolina was initiated in 1995. The curves characterize a broad range of streams within the Piedmont physiographic province. Small watersheds or deviations in valley slope, land use, or geologic substrates may not be accurately described by the curves; therefore, verification of individual watersheds may be necessary. Off-site reference reaches will be utilized in conjunction with regional curves for detailed planning and characterization of this mitigation project. To the extent that channel form or shape is important in these projects, these regional curves provide a reliable stream restoration tool in the Piedmont of North Carolina.

N Shown Dsb: May 2007 ProJsd No.: 07-3480 ~i ' 3.0 STREAM CHANNEL AND FLOODPLAIN RESTORATION Stream Restoration on New Location Stream restoration will be performed along Reaches 2, 3, and 6 as depicted in Figure 4. The work is expected to entail 1) culvert removal, 2) belt-width preparation, 3) channel excavation, 4) spoil stockpiling, 5) channel stabilization, 6) channel diversion, and 7) ditch backfill. Belt-width corridor preparation will entail culvert removal, channel staking, floodplain clearing and grubbing, and any necessary grading prior to channel excavation. After the floodplain has been prepped, the proposed design channel will be staked and/or clearly marked to the design parameters. Spoil material excavated during floodplain grading will be stockpiled adjacent to the existing channels to be abandoned and backfilled after construction of the new channel is complete. Once belt-width corridor preparation is complete, the proposed channel will be excavated to the average width, depth, and cross-sectional area derived from reference reach studies and detailed measurements of the onsite reach. Stream banks and the belt-width area of constructed channels will be immediately planted with shrub and herbaceous vegetation. Root mats may also be selectively removed from adjacent areas and placed as erosion control features on channel banks. Once the proposed design channel has been excavated and stabilized, abandoned channels will be backfilled utilizing spoil material stockpiled from floodplain grading and channel excavation. In-stream Structures The use of in-stream structures for grade control and habitat are essential for successful stream restoration. In-stream structures may be placed in the channel to elevate local water surface profiles in the channel, potentially flattening the water energy slope or gradient. The structures would likely consist of boulder-size rock vanes, j-hook vanes, and/or step-pool devices designed primarily to direct stream energy into the center of the channel and away from banks. In addition, the structures would be placed in relatively straight reaches to provide secondary (perpendicular) flow cells during bankfull events. Stream Restoration In-Place As depicted in Figure 5, stream restoration on Reach 6, and Reach 7 will be performed along the existing channels, including: 1) cessation of current land management practices adjacent to the streams; 2) excavation of active floodplain benches adjacent to sections of the incised channels; 3) installation of in-stream and bank structures to promote bed variability and aquatic habitat; and 4) planting with native floodplain vegetation. Planting with native vegetation is discussed in detail in Section 4.0 of this document. Stream Preservation and Management Preservation is being proposed on approximately 1000 linear feet of stream labeled as Reach 8 in Figure 5. Based on preliminary analysis and field investigations, this reach maintains a relatively intact, forested riparian buffer and stable stream bed form. Long term management will include periodic inspection and removal of garbage or contaminants from streams. These areas will also be supplemental planted with native hardwood species characteristic of a Piedmont/Mountain Bottomland Hardwood Forest, as described in Classification of the Natural Communities of North Carolina (Schafale and Weakley 1990). These areas will be protected in Carolina Golf Club Stream Mitigation Plan Page 5 of 8 Charlotte, Mecklenburg County, North Carolina perpetuity through the establishment of restrictive covenants encompassing the riparian corridor. 4.0 VEGETATION. COMMUNITY RESTORATION Deep-rooted, riparian vegetation will be established within 5.3 acres of restored floodplain and riparian buffer. Planting vegetation on cleared stream banks is proposed to reestablish vegetation community patterns within the stream corridor, associated side slopes, and transition areas. Revegetating the floodplain and stream banks will provide stream bank stability, shade and cool surface waters, filter pollutants from adjacent runoff, and provide habitat for area wildlife. The vegetated stream buffer will extend to a minimum of 30 feet on both sides of the stream. Scarification of floodplain surfaces may be required prior to planting. Variations in vegetative planting may occur based on topographic locations, line of sight requirements for the golf course fairways, and hydraulic conditions of the soil. Vegetative species composition should mimic reference forest data and onsite observations. Based on reference communities in the region, species expected for this project may include the following elements. Piedmont Bottomland Forest 1) Mockernut Hickory (Carya tomentosa) 2) Pignut Hickory (Carya g/abra) 3) American Beech (Fagus grandifolia) 4) White Oak (Quercus a/ba) 5) Northern Red Oak (Quercus rubra) 6) Green Ash (Fraxinus pennsylvanica) 7) Red Maple (Acer rubrum) 8) River Birch (Betu/a nigra) 9) American Sycamore (P/afanus occidentalis) 10) Willow Oak (Quercus phe/los) 11) Water Oak (Quercus nigra) 12) American Elm (Ulmus americans) 13) Shagbark Hickory (Carya ousts) 14) Black Gum (Nyssa sy/vatica) 15) Black Walnut (Juglans nigra) 16) Yellow Poplar (Liriodendron tulipifera) Stream-Side Shrub Assemblage and Line-Of-Sight Corridors 1) Black Willow (Salix nigra) 2) Hackberry (Celtis laevigata) 3) Box Elder (Acer negundo) 4) Ironwood (Carpinus caroliniana) 5) Swamp Dogwood (Corpus amomum) 6) Tag Alder (Alnus serru/ata) 7) Buttonbush (Cephalanthus occidentalis) 8) Elderberry (Sambucus canadensis) 9) Arrow-wood Viburnum (Viburnum dentatum) 10) Possumhaw Viburnum (Viburnum nudum) 11) Highbush Blueberry (Vaccinium corymbosum) Carolina Golf Club Stream Mitigation Plan Page 6 of 8 Charlotte, Mecklenburg County, North Carolina 12) Sourwood (Oxydendrum arboreum) 13) American Holly (Ilex opaca) 14) Flowering Dogwood (Corpus florida) 15) Downy Serviceberry (Amelanchier arborea) Species distribution and densities are expected to be determined during development of the detailed specifications for channel and floodplain restoration work. Nuisance Species Management Prior fo the revegetation phase of the project, nonnative floral species will be removed. Exotic species currently identified within the project area include multiflora rose and Chinese privet. These species are fast growing and tend to overwhelm and out-compete the plant communities proposed for stabilization of the new stream channel. These species will be controlled as needed within the riparian buffers by cutting and grubbing in addition to chemical herbicide treatment approved for wetland applications. Beavers and other potential. nuisance species will be monitored over the course of the 5-year monitoring period. Appropriate actions will be taken to ameliorate any negative impacts regarding vegetation development and/or water management on an as-needed basis. 5.0 MONITORING PLAN Monitoring of Site restoration efforts will be performed for five years or until agreed upon success criteria are fulfilled. Monitoring is proposed for the stream channel and vegetation communities. Stream Monitoring Annual fall monitoring will include development of channel cross-sections on riffles and pools, pebble counts, and a water surface profile of the channel. The data will be presented in graphic and tabular format. Data to be presented will include 1)cross-sectional area, 2) bankfull width, 3) average depth, 4) maximum depth, 5) width-to-depth ratio, 6) meander wavelength, 7) belt- width, 8) water surface slope, 9) sinuosity, and 10) stream substrate composition. A photographic record of preconstruction and postconstruction conditions will also be compiled. Stream Success Criteria Success criteria for stream restoration will include 1) successful classification of the reach as a functioning stream system (Rosgen 1996a) and 2) channel variables indicative of a stable stream system. Visual assessment of in-stream structures will be conducted to determine if failure has 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. Veaetation Monitoring After. planting has been completed in winter or early spring, an initial evaluation will be performed to verify planting methods and to determine initial species composition and density. Supplemental planting and additional Site modifications will be implemented, if necessary. During quantitative vegetation sampling in early fall of the first year, sample plots will be randomly placed within the Site. In each sample plot, vegetation parameters to be monitored include species composition and species density. Visual observations of the percent cover of shrub and herbaceous species will also be recorded. Carolina Golf Club Stream Mitigation Plan Page 7 of 8 Charlotte, Mecklenburg County, North Carolina Vegetation Success Criteria An average density of 320 stems per acre of Character Tree Species must be surviving in the first three monitoring years. Subsequently, 290 Character Tree Species per acre must be surviving in year 4 and 260 Character Tree Species per acre in year 5. Contingency Stream In the event that stream success criteria are not fulfilled, a mechanism for contingency will be implemented. Stream contingency may include, but may not be limited to 1) structure repair and/or installation; 2) repair of dimension, pattern, and/or profile variables; and 3) bank stabilization. The method of contingency will be dependent upon stream variables that are not in compliance with success criteria. Primary concerns, which may jeopardize stream success, include 1) structure failure, 2) headcut migration through the Site, and/or 3) bank erosion. Vegetation Contingency If vegetation success criteria are not achieved based on average density calculations from combined plots over the entire restoration area, supplemental planting will be performed with native tree species approved by regulatory agencies. Supplemental planting will be performed as needed until achievement of vegetation success criteria. 6.0 FINAL DISPENSATION After restoration is completed, Carolina Golf Club will maintain ownership of the stream corridors. In addition, restrictive covenants will be placed over the land area to protect the conservation areas. Carolina Golf Club will remain responsible for project implementation, achievement of success criteria, and long term management of the property. 7.0 REFERENCES Griffith, G.E., J.M. Omernik, J.A.
