Several issues were discussed which were associated with the design and construction of stream restoration projects in the Triassic Basin in general and in particular how these issues relate to the case of the Lick Creek Project. Primarily these issues involved the process of sediment transportation as it relates to sand and silt bed streams, the appropriate use of shear stress and stream power to evaluate sediment transport, the appropriate use of reference reach data, and the appropriate methods for determining DSO. At the time of our conversation I was unable to confmn whether or not all of these issues had been taken into consideration during the design of this project. We are, however, aware of these concerns and will evaluate the sediment transport related issues of the channel design. If the result of this evaluation confirms any of the concerns that were discussed we will notify you. Also, please rote that where appropriate -V e will incorporate elements into the construction of the channel that will aid in the long term stability and appropriate sediment transport of the channel. If you require any additional information, please advise. Sincerely, Wolf Creek Engineering tiran Ginn, P.E.

RS appreciates the time and care spent in the review of its application and is pleased to offer the following responses to the questions raised in the referenced letter. 1. The project site is in the Triassic Basin. Please explain the use of reference streams in Anson County. The Site is located within the Chatham Group, Sanford-Durham sub-basin of the Triassic Basin. The references are located in the Wadesboro sub-basin of the Triassic Basin. The goal of the reference reach search was to identify one or more stable reference reaches with the correct sediment type, valley type and slope as close as possible to the project site, within the same eight-digit hydrologic unit AND within the Triassic Basin. Finding a reference within the Triassic Basin was determined to be most important because the streams within this ecoregion are believed to act and function differently than similar streams in other ecoregions. Therefore, the reference reach search encompassed the 03030004 CU as well as the entire Triassic Basin within North Carolina. However, finding a suitable, stable stream was difficult. The search was exhaustive and included field reviewing every Pilot Mill • 1101 Haynes St., Suite 107 • Raleigh, NC 27604 • www.restorationsystems.com • Phone 919.755.9490 • Fax 91.9.755.9492 W,* Page 2 November 15, 2005 j o14F W AT ?RQG Michael F.

Attn: Mr. Randy Turner 1101 Haynes Street, Suite 107 Raleigh, NC 27604 Subject Property: Lick Creek and Wallace Branch Stream Restoration REQUEST FOR MORE INFORMATION Dear Mr. Turner: On October 5, 2005, the Division of Water Quality (DWQ) received your application for a 401 Water Quality Certification. Upon review of your application package, DWQ found several issues that require additional information in order to process your application to impact protected wetland, streams and/or buffers on the subject property. Unless we receive the additional information requested below, we will have to move toward denial of your application as required by 15A NCAC 2H.0506 and will place this project on hold as incomplete. Please provide the following information so that we may continue to review your project: 1. The project site is in the Triassic Basin. Please explain the use of reference streams in Anson County. 2. Please explain how the reference streams were used in the design of the restored reaches. The design seems to be based on the Rural Piedmont Regional Curve. Additionally, since the area may be urbanizing due to the US 421 Bypass (noted in Section 2.3), it may be advisable to use a curve that tends towards a more urban character. 3. Triassic Basin clays act differently from most other soils. For example, the two reference sites have a sinuosity of 1.06 and 1.39, respectively. However, three of the seven restoration reaches have sinuosity of 1.63 to 1.86 (much higher than appears to be supported by actual Triassic streams). Please explain this aspect of your stream design. DWQ is concerned that the increased sinuousity [effectively changing the slopes in the restored reaches to be less than half of the reference reaches], will lead to flow ceasing more frequently during dry periods. 4. DWQ notes that classic Triassic Basin streams have fairly homogeneous clay bottoms, with very little other material in them except for the occasional stick or rock. The reported D50s range from 1-4mm. Where rocks are not part of the landscape, DWQ usually recommends thaf restoration projects use only wood structures. At present, the grade control structures are proposed to be largely rock material. 5. Finally, you should be advised in advance that DWQ will require monitoring of benthic macroinvertebrates as part of the monitoring proposal. Four sites should be sufficient. These would include: a. A site located at the bottom of the project b. A site located at the confluence of Lick and Wallace 401 Oversight/ Express Review Permitting Unit 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 2321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 Phone: 919-733-1786 / FAX 919-733-6893 / Internet: http://h2o.enr.stAte.ne.us/ncwetlands NO a Carolina Atura!!y An Equal Opportunity/Affirmative Action Employer- 50% Recycled/10% Post Consumer Paper Lick Creek Stream Restoration Page 2 of 2 October 25, 2005 c.

For some reason I thought this was a regular permit, not express, so we had more time. All of my comments come from the fact that this project, unlike anything else, is located in the Triassic Basin - a very wierd and understudied place. For this reason I am willing to overlook that their reference streams are in Anson County where the project is in Lee, usually that's too far away. Since they went to so much work to find these reference streams, I would hope that they use them for stream design, however for the most part they didn't. It appears that they took their design criteria entirely off of the Rural Piedmont Regional Curve, which may be OK for most soil types, but Triassic Basin clays act differently from most other soils with rocks in them. For instance, the 2 reference sites have sinuosity of 1.06 and 1.39, however 3 of the 7 restoration reaches have sinuosity of 1.63 to 1.86 - much higher than appears to be supported by real Triassic streams. Maybe they have some other information showing that the extra sinuosity is warrented for more that just making more stream length to get more credit. The extra sinuosity makes the slopes in the restored reaches less than half of in the reference reaches and I am afraid that this might lead to flow ceasing more frequently and stressing the bugs (changing community from stream bugs to pond bugs). The classic Triassic stream has a fairly homogeneous clay bottom, with very little else in it except the occasional stick or rock. All reported D50s range from 1-4mm, so this may be the case here to. In the coastal plain, where rocks are not part of the landscape, we usually suggest that restorations be done using only wood structures. In these Triassic streams, where rocks seem to be equally foreign, should we require the same? Right now all of their grade control are rock structures. Since this is the Triassic Basin, an area where we have no previous data, I would also like to require monitoring of benthic macroinvertebrates as part of their monitoring proposal. Probably 4 sites would be enough: 1 at the bottom of the project, one just above the confluence of Lick Cr and Wallace Cr and a reference (probably upstream of the project since the reference reaches they examined are probably too small). As usual, 1-2 years preconstruction and 3 years post construction with success being a significant increase in the species of bugs and/or their tolerance. Finally, I just wanted to give kudos to the designer who had the guts to make a project with bends of different sizes and shapes. It was so refreshing to look at a stream pattern that did not come off an oscilloscope. Larry Cynthia F Van Der Wiele wrote: Hey Larry, Any comments for this?

These stream reaches have been severely degraded over the years due to unrestricted use by livestock. This full delivery project was proposed by RS to address stream restoration needs identified in the Cape Fear River Basin (CU 03030004) by the Ecosystem Enhancement Program. It is important to point out that RS previously applied for Nationwide authorization for the same project on June 15, 2005, but subsequently discovered that the design of the stream restoration was severely flawed. The Division of Water Quality and Corps of Engineers were notified that the application was being withdrawn. RS has since commissioned a re-design effort and has invested heavily in peer review of the finished product. Five copies of this application and its attachments/enclosures are being provided to the Division of Water Quality (DWQ). A separate application package including Erosion & Sedimentation Control plans is being sent to the North Carolina Division of Land Quality. In addition to half-size (11" X 17") construction plan sheets and technical specifications, this application package contains a copy of the Federal Highway Administration (FHWA)-approved Categorical Exclusion (CE) Action Classification Form, the Amended Stream Restoration Plan, the conservation easement (and survey), and DWQ Stream Classification Forms. Please note that Section 7 (ESA) and Section 106 (NHPA) issues were fully addressed in the Feasibility Study as indicated by the approval of the CE by the FHWA. In summary, no suitable habitat for listed species is located within the project area and no historic properties are listed for the project area by the State Historic Preservation Office.

The applicant may attach drawings of alternative, lower-impact site layouts, and explain why these design options were not feasible. Also discuss how impacts were minimized once the desired site plan was developed. If applicable, discuss construction techniques to be followed during construction to reduce impacts. Avoidance: In order to restore lost functions to Lick Creels, it was necessary to reconfigure its pattern, profile and dimensions Excavating a totally new channel separate from the existing channel would not have been practicable due to the large volume of surplus waste (soil) to be displaced Minimization: A temporary pump-around system will be utilized during construction and each section will be stabilized as it is completed. All appropriate erosion and sediment control practices will be utilized. VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on January 15, 2002, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.

Project Description: The Lick Creek Stream Restoration Site is located approximately 2.6 miles northeast of the City of Sanford in rural Lee County. It includes 40 acres of floodplain, 5,000 linear feet of perennial, second/ third order stream designated as Lick Creek and 3,500 linear feet of perennial, second order stream designated as Wallace Branch. The existing channels are highly degraded due to unrestricted livestock access, riparian vegetation removal, and increasing non-point source runoff from the developing watershed. The proposed project consists of 100 percent restoration, as defined in the Stream Mitigation Guidelines (U.S. Army Corps of Engineers, Wilmington District, April 2003). The proposed stream restoration process will involve: 1) raising the base elevation (profile) and constructing a new bankfull channel; 2) backfilling the abandoned, existing channel; 3) erecting livestock exclusion fencing; 4) invasive species removal; and 5) reestablishing a diverse native riparian buffer. This project will provide 9,500 linear feet of Stream Mitigation Units with the Cape Fear River Basin Cataloging Unit (CU) 03030004. B. Purpose and Need: The NCDENR Ecosystem Enhancement Program is responsible for providing compensatory mitigation for authorized wetland, stream and riparian buffer impacts associated with transportation-related infrastructure and economic development. As part of their overall mitigation strategy, the EEP published a request for proposals (RFP) in December 2003 seeking Full Delivery Projects that would provide stream mitigation credits within the Cape Fear River Basin CU 03030004. In response to the RFP, Restoration Systems, LCC submitted the "Lick Creek Stream Restoration Site, Lee County, North Carolina Technical and Cost Proposal" on March 24, 2004. C.

This is a stream restoration project based upon natural channel design methodologies that will use a Rosgen Priority Level 1 approach to restore stable "EX4" stream channels on the historic floodplain by raising the base elevation (profile) and constructing a new bankfull channel. The broad floodplain provides the opportunity to increase the stream belt width and sinuosity through the establishment of a more meandering planform. It is expected that the restored channel will be constructed both off-line and on-line, meandering through the protected stream riparian corridor. Modifications will also be made to the profile in order to re-establish a natural riffle and pool bed morphology with appropriate pool spacing. 5 r G.

September 30, 2005 EXECUTIVE SUMMARY ' Restoration Systems is submitting this Restoration Plan to the North Carolina Ecosystem Enhancement Program (EEP) for the Lick Creek Stream Restoration Full Delivery Project with intentions of restoring a degraded section of Lick Creek and Wallace Branch located within Lee ' County, North Carolina. The project reach is approximately 8,500 linear feet. The project is located within the Cape Fear River.Basin, Cataloging Unit 03030004. The site consists of 51 acres of floodplain, 5,371 linear feet of perennial, second/third order stream designated as Lick Creek and 3,512 linear feet of perennial, second order stream designated as Wallace Branch. The existing channels are highly degraded due to unrestricted livestock access, channel straightening activities, riparian vegetation removal, and increasing non-point source runoff from ' the developing watershed. The project site is in a rural setting currently pastured and contains open fields of grasses with woody vegetation confined to some areas adjacent to the existing stream reaches. The surrounding area is rural in nature, with some residential development. The project reach has active channel widening characterized by severe bank erosion. ' The primary goals and objectives of the restoration of Lick Creek focus on improving local water quality, enhancing flood attenuation and restoring aquatic and riparian habitat. These goals and objectives will be accomplished by: ' Reestablishing stream stability and capacity to transport watershed flows and sediment load by restoring stable channel morphology supported by natural in-stream habitat and grade/bank stabilization structures; ¦ Reducing non-point source sedimentation and nutrient inputs into the identified project reaches through the elimination of accelerated bank erosion, exclusion of livestock, and reestablishment of native riparian buffers greater than 50 feet in width; and ' Enhancing the capacity of the site to mitigate flood flows by improving the stream's connection to its floodplain. ' The proposed stream dimension, pattern, and profile was based on the detailed morphological criteria and hydraulic geometry relationships developed from reference reaches - stable portions of unnamed tributaries to Reedy Creek, a second order rural stream located in Anson County. The reference reaches are located in the same hydrophysiographic province as the ' project stream. The reference also has similar land use, valley slope, and. sediment distribution as the project site. The restoration design is based on a Priority Level 1 approach that will improve connection of approximately 9,500 linear feet of meandering, bankfull channel to its previous floodplain and provide stable flow maintenance and sediment transport. The design bankfull stage will equal the floodplain elevation. The design stream profile will restore stable bed morphology including appropriate riffle-pool sequencing. Cross-vane, J-Hook vane (J-Vane), and vane instream structures have been integrated in the design to provide grade control, assist in stabilizing the banks and reduce the burden of energy dissipation on the channel geometry. Biodegradable coir fiber matting will be used to provide temporary stabilization on the newly graded streambanks. The confluence of tributaries within the project reach will be incorporated and stabilized with a grade control structure to match the proposed grade of the restored main ' channel. Excavated materials from the design channel will be used to backfill the abandoned portions of the existing channel. Native woody and herbaceous species will be used to establish at minimum a fifty (50) foot wide riparian buffer on each side of the restored reach. The riparian buffer planting plan consists of 1 zones in which different species are associated. Live staking with appropriate native species will also be used along the streambanks to provide natural stabilization as well as temporary seeding and planting of native herbs and grass seeding. Monitoring shall consist of the collection and analysis of stream stability and riparian/stream bank vegetation survivability data to assist in the evaluation of the project in meeting established restoration objectives. Specifically, the success of channel modification, erosion control and re- vegetation parameters will be assessed using measurements of stream dimension, pattern, and profile, site photographs, and vegetation sampling. 1 1 1 TABLE OF CONTENTS Executive Summary ...................................................................................................................1 1.0 Introduction

This Plan presents detailed information regarding the existing site and watershed conditions, the morphological design criteria developed from a selected reference reach, and the project design parameters based upon natural channel restoration methodologies. 1.1 GENERAL PROJECT DESCRIPTION Lick Creek is located approximately 2.6 miles northeast of the City of Sanford in rural Lee County, North Carolina (Figure 1: Vicinity Map). The site consists of approximately 51 acres of floodplain, 5,371 linear feet of stream designated as Lick Creek, and 3,512 linear feet of stream designated as Wallace Branch (Figure 2: Project Location Map). These reaches consist of perennial, second, and third order streams that have historically been impacted by riparian and bank vegetation removal, the introduction of agricultural ditch inputs, channel straightening, unrestricted livestock access, and the increasing development of the contributing drainage area. Existing land use within the site consists of forested areas and pasture. The site is located within the floodplains of Wallace Branch and Lick Creek so elevations remain relatively level. Past land management activities have included timber harvest with subsequent land clearing for pastoral uses. 1.1.1 USGS and NCDWQ River Basin Designations The project reach is located in the Lick Creek watershed of the Cape Fear River Basin (United States Geological Survey (USGS) 14-digit Hydrologic Unit 03030004010010) within North Carolina Division of Water Quality (NCDWQ) sub-basin 03-06-07. The 03-06-07 sub-basin contains all of the Lick Creek drainage area as well as all other drainages to the 25-river miles of the Cape Fear River extending from near the confluence at Lick Creek in Lee County to near Buies Creek in Harnett County. This sub-basin is primarily forested, although agriculture accounts for a significant portion of the sub-basin. 1.1.2 NCDWQ Surface Water Classification The NCDWQ assigns surface waters a classification in order to help protect, maintain, and preserve water quality. Lick Creek and Wallace Branch are classified as WS-IV waters protected as water supplies which are generally in moderately to highly developed watersheds. Local programs to control non-point source and stormwater discharge of pollution are required. These waters are additionally classified as suitable for aquatic life propagation and survival, fishing, wildlife, secondary recreation, and agriculture. Based upon monitoring station data collected in 2004, NCDWQ has assigned a water quality use support rating of "impaired" to 10.3 freshwater miles of the main stem of Lick Creek due to elevated levels of turbidity, fecal coloform bacteria, and below standard levels of dissolved oxygen (NCDENR 2005). Increasing watershed development and non-point source pollution have been identified as probable causes of impairment. I Lick Creek Stream Restoration Plan Lee County, North Carolina 1 1.2 PROJECT GOALS AND OBJECTIVES ' The goals and objectives of the Lick Creek Stream Restoration Project focus on improving local water quality, enhancing flood attenuation, and restoring aquatic and riparian habitat. These goals will be accomplished by: ¦ Reestablishing stream stability and capacity to transport watershed flows and sediment load by restoring stable channel morphology supported by natural in-stream habitat and grade/bank stabilization structures; ' Reducing non-point source sedimentation and nutrient inputs into the identified project reaches through the elimination of accelerated bank erosion, exclusion of livestock, and reestablishment of native riparian buffers greater than 50 feet in width, and ¦ Enhancing the capacity of the site to mitigate flood flows by improving the connection of the stream to its floodplain. 1 Lick Creek Stream Restoration Plan Lee County, North Carolina 2.0 WATERSHED CHARACTERIZATION 2.1 GENERAL DESCRIPTION The project site is located in a rural setting within the Piedmont Physiographic Province. The topography is characterized by nearly level to steep upland areas (Stimpson 1989). The headwaters of both Lick Creek and Wallace Branch form to the west and south of the project site, along the fringe of the Sanford City Limits. Elevations within the drainage area range from a low of 200 feet above mean sea level (AMSL) within the bed of Lick Creek to a high of approximately 400 feet AMSL along the southwestern drainage area boundary near Sanford (USGS 1970, 1974, 1977, & 1993). 2.2 DRAINAGE AREA The total drainage area for the project is 14.0 mil (Figure 3: Watershed Extent). The contributing area to the Wallace Branch project reach is 4.9 mil while the contributing area to the Lick Creek project reach before the confluence with Wallace Branch is 8.9 mil. Prior to reaching the downstream limits of the project area, an additional 0.2 mil drains to the project reach. 2.3 LAND USE AND DEVELOPMENT POTENTIAL Land use in the drainage area consists primarily of forest, pasture, and agriculture. Additional land uses include rural residential development, secondary surface transportation routes, and suburban residential and commercial/industrial development in the headwaters. The headwaters of the contributing drainage area includes the eastern portion of the Sanford Municipal Limits and Extra- territorial Jurisdiction (ETJ) which lies approximately 2.6 miles southwest of the site (Figure 4: Watershed Land Cover). Lee County experienced a population growth of approximately 19 percent from 1990 to 2000 and is predicting a 16 percent increase by 2010. Most of this growth has occurred directly north of and south of the City of Sanford adjacent to the major transportation routes of US-1, US-15, US-501, and US-421. Development potential within the contributing drainage area would be considered high based solely on the proximity of the expanding Sanford urban area and the existing US-1 and US-421 transportation routes. However, the pending US-421 Bypass Transportation Improvement Project around the eastern side of Sanford and through the middle of the site's contributing drainage area serves to further increase this development potential. The NCDOT is currently finalizing the design of the US-421/NC-87 Bypass of Sanford (Transportation Improvement Program Project R-2417). The proposed design is approximately 11 miles in length extending west of the City of Sanford from SR 1400 (Cumnock Road) to NC-87 west of SR 1138 (Harvey Faulk Road). Right-of-way acquisition is in progress with construction scheduled to begin in Fiscal Year (FY) 2008 (NCDOT 2005). Relatively lower residential housing costs for commuters to the Research Triangle Park (RTP)/Raleigh/Cary job market and a strong commitment by County officials to offer economic incentives to attract manufacturing facilities support predictions that expansion of development in the site area is likely to accelerate in conjunction with the construction of the US-421 Bypass. According to the Lee County Economic Development Corporation (EDC), "local access will become Lick Creek Stream Restoration Plan Lee County , North Carolina ' even stronger when the US-421 Bypass is completed, opening southern Lee County for easy [freight transfer].„ 2.4 WATER QUALITY The location of the proposed stream restoration along Lick Creek and Wallace Branch is important to local water quality due to its proximity to the City of Sanford's drinking water intake on the Cape Fear River (approximately two miles downstream of Lick Creek's confluence with the Cape Fear ' River near the NC-42 river crossing). In the future, when overflow residential development from RTP and existing residential/industrial development in Sanford expands, this restored and protected site will afford a degree of protection to local water quality. ' As part of their land use planning initiatives, Sanford and Lee County officials are actively developing protection initiatives for environmentally sensitive areas by setting long-term goals that include: 1) preserving stream valleys for open space corridors and passive recreation; 2) ' identifying, protecting, and enhancing ecologically valuable land and surface water for the current and future community residents; 3) promoting Lee County as a "Green" community; and 4) creating buffering along all creeks, rivers, and floodplains in the community. Their specific buffering goals include establishing 30-foot minimum buffers along all creeks and streams, and a 300-foot minimum buffer adjacent to all riverbanks including the Little River, Deep River, and Cape Fear River. ' The proposed project is supportive of these local water quality goals, will serve to address existing deficiencies with the WS-IV watershed, and will assist the Ecosystem Enhancement Program (EEP) in meeting mitigation goals in the Cape Fear River Basin USGS eight-digit 03030004 cataloging unit. ' 2.5 SIGNIFICANT CULTURAL AND NATURAL RESOURCES 2.5.1 Historical Resources ' A review of available records at the North Carolina Department of Cultural Resources - State Historic Preservation Office (SHPO) indicates a survey for Lee County has been completed. There are numerous resources mapped within the contributing drainage area to the proposed project. ' However, only two structures, designated as potential 50-year old structures for which evaluations have not been conducted, occur within the vicinity of the site. These structures are located on upland areas approximately 500 feet from the existing Lick Creek channel and are well outside of the proposed conservation easement boundary. 2.5.2 Archaeological Resources ' A review of available records indicates that no known archaeological sites are recorded within the project site or adjacent areas and no archeology survey is recommended. r 2.5.3 Rare/Threatened/Endangered Species and Critical Habitats A review of the North Carolina Natural Heritage Program (NCNHP) database was conducted to determine the presence of any rare, threatened, or endangered (RTE) species or critical habitats on or near the site. Additionally, existing site conditions were evaluated in order to determine if suitable habitat exists on the site for supporting listed species occurring within the county. No Lick Creek Stream Restoration Plan Lee County, North Carolina I listed occurrences of RTE species/critical habitats or existing suitable habitat for supporting such ' occurrences were identified on or near the site (NCNHP 2004). Although no protected species were identified within the project area, the proposed project has the ' potential to restore habitat suitable for supporting a listed species. Historic and current occurrences of harperella (Ptilimnium nodosum) were indicated on islands in the Deep River approximately seven miles north of the project stream (NCNHP 2004). Harperella is federally and state listed as endangered. Harperella is an annual herbaceous plant with a slender, smooth stem and hollow, quill-like leaves. Its flowers are small, white, and arranged in umbels similar in ' appearance to Queen Anne's lace (Daucus carota). Harperella grows in thin streamside soils between cobble and in rock crevices. Populations of the species are dependant on seasonal fluctuations of water levels. Sustained periods of higher winter and spring water levels provide ' protection from cold and ice, and removal of competing species. Lower summer flows expose seedbed and rooting strata (NCDENR 2001a). It is anticipated that the restored stream conditions will eliminate excessive silty, fine-grained sediment and produce the seasonal flood regime suitable for this species to thrive. ' I Lick Creek Stream Restoration Plan Lee County, North Carolina 3.0 PROJECT SITE EXISTING CONDITIONS SURVEY 3.1 GENERAL SITE DESCRIPTION ' The project site is located in a rural area outside the City of Sanford.. The majority of the project site is currently used for pasture and dominated by open fields of grasses with woody vegetation confined to areas adjacent to the existing stream reaches and along a section of Lick Creek that is partially forested (Figure 5: Project Site Aerial). The project reach crosses one roadway, Lower Moncure Road (SR 1002). The site consists of approximately 51 acres of floodplain, 5,371 linear feet of stream designated as Lick Creek and 3,512 linear feet of stream designated as Wallace ' Branch. These reaches consist of perennial, second, and third order streams that have historically been impacted by riparian and bank vegetation removal, agricultural ditch inputs, channel straightening, unrestricted livestock access, and increasing development of the contributing drainage area. Photographs of representative site conditions are provided in Appendix A (Project Site Existing Conditions Photographs). 3.2 GEOLOGY AND SOILS ¦ The project site is located in the southeastern portion of the Piedmont Physiographic Province, specifically within the Chatham Group, Sanford-Durham sub-basin of the Triassic Basin ecoregion. ' The Triassic Basin consists of dissected irregular plains with. some low rounded hills and ridges. This ecoregion has low to moderate gradient streams with relatively wider floodplains than other Piedmont ecoregions (Griffith et al 2002). According to the Soil Survey of Lee County (Stimpson, 1989), predominant soil groups found within the contributing watershed include Mayodan-Pinkston, Creedmoor-White Store, and Chewacla- Wehadkee-Congaree (Figure 6: Soils Map). ' Soils within the project site are predominately mapped as Congaree silt loam (Cp). The site also includes minor areas of Chewacla silt loam (Ch), present at the upstream end of the floodplain of Lick Creek, and Mayodan fine sandy loam (MfE), found on the small upland inclusion south of Wallace Branch near Lower Moncure Road (Stimpson 1989). Congaree silt loam, a thermic Typic Udifluvent, is a well-drained soil that generally occurs in narrow bands on nearly level slopes (zero to two percent) parallel to streams where channels are deep enough to provide good drainage. They were formed in Tine loamy material washed from soils on uplands. Congaree soils typically contain inclusions of Chewacla soils, which have hydric inclusions, and Wehadkee soils, which are hydric soils. Congaree °soils are frequently flooded for very brief periods, have moderate permeability, and low shrink-swell potential. The seasonal high ' water table can be as shallow as two and a half feet. In a typical profile, the surface layer is silt loam approximately nine inches thick with underlying material to a depth of 52 inches that is friable silt loam stratified with thin lenses of fine sandy loam. Below this, to a depth of about 65 inches is silty clay loam. Congaree soils are classified in the B hydrologic soil group (Stimpson 1989). If destabilized, the low cohesive strength of these soils makes them highly vulnerable to active erosional processes such as slab and rotational failure due to basal cleanout, especially in the ' absence of adequate streambank vegetation. Chewacla loam, a thermic Fluvaquentic Dystrochrept, is described as a nearly level and somewhat poorly drained soil found within long, narrow floodplains along major streams. The soil is Lick Creek Stream Restoration Plan Lee County, North Carolina moderately permeable, and available water capacity is high. The seasonal high water table is a half foot to one and a half feet below the surface, which allows frequent flooding for brief periods. Chewacla soils typically contain small inclusions of Congaree soils, which have hydric inclusions, and Wehadkee soils, which are hydric soils located in depressions. Chewacla soils are mostly used as woodland with small areas used as cropland or pasture (Stimpson 1989). 3.3 EXISTING RIPARIAN BUFFER AND NATURAL COMMUNITIES The project site is in a rural setting with agricultural activities occurring in close proximity. Such activities include pasturing of cattle and a fowl production facility. Two vegetative communities were identified on site, Agricultural Grass and Piedmont/Mountain Bottomland Forest. The existing stream buffer in the farming area is not regarded as a naturally occurring system. The system is a result of human induced disturbance. The pastured areas bordering the project channels are primarily vegetated with typical field grasses such as fescue (Festuca sp.) and other herbs and shrubs. Other herbaceous species include chickweed (Stellaria media), curly dock (Rumex crispus), white clover (Trifolium repens), and dog fennel (Eupatorium capillifolium). Scattered individuals or small clumps of shrubs and trees were also noted in these areas, predominantly sweetgum (Liquidambar styraciflua), red maple (Acer rubrum), eastern redcedar (Juniperus virginiana), blackberry (Rubus sp.) and Chinese privet (Ligustrum sinense). The canopy above the Lick Creek reach contains species indicative of a Piedmont/Mountain Bottomland Forest (Schafale and Weakley 1990). The dominant canopy species in this area were American sycamore (Platanus occidentalis), sweetgum, river birch (Betula nigra), green ash (Fraxinus pennsylvanica), and box-elder (Acer negundo). Ironwood (Carpinus caroliniana) and American elm (Ulmus americana) were also present. The shrub level was fairly dense throughout these areas and was dominated by Chinese privet, giant cane (Arundinaria gigantea), and saplings of the canopy tree species. Grape (Vitis spp.), greenbrier (Smilax rotundifolia), poison ivy (Toxicodendron radicans), and Japanese honeysuckle (Lonicera japonica) were present throughout. The most common species rooted in the streambanks was Chinese privet. The canopy of the forested areas beyond the levee on the adjoining property to the south and east of the stream has been altered by forestry operations. Where this logging activity was conducted, the canopy was approximately ten feet high and the dominant species were sweetgum, box-elder, red maple, and American hazel (Corylus americana). Chinese privet, grape, greenbrier, poison ivy, and Japanese honeysuckle were -observed throughout. An area to the northwest of the confluence of Lick Creek and Wallace Branch was also identified as a Piedmont/Mountain Bottomland Forest community. The species composition was similar to the other bottomland forest areas identified; however, this area has a higher abundance of sweetgum and river birch. Hydrologic conditions observed in the field indicated frequently saturated conditions and this area may be considered a jurisdictional wetland. This area totals approximately three and a half acres, but was not subject to a jurisdictional determination. Of this acreage, one-half to one acre are included in the planned restored stream/riparian corridor easement. The area will not be impacted by the stream design or construction. 7 I Lick Creek Stream Restoration Plan Lee County, North Carolina 1 3.4 EXISTING STREAM CHARACTERISTICS 3.4.1 Morphological Description A Rosgen Level II Assessment was conducted in March 2004 to determine restoration potential of the site and Rosgen Level III Assessment in January 2005 to gather existing stream dimension, pattern, and profile data (i.e., width, depth, cross-sectional area, slope, radius of curvature, belt width, meander length), develop morphological parameters (i.e., W/D ratio, entrenchment ratio, radius of curvature to bankfull width ratio, sinuosity). The project reach is subdivided into five sections due to the road crossing, confluence of Wallace Branch and Lick Creek, and the change in drainage areas. Data developed from this assessment are summarized below and detailed data records are presented in Appendix B (Project Site Existing Conditions Data). Table 1.

E-type streams are characterized as slightly entrenched with high sinuosity riffle-pool channels (stream length/valley length) and greater than a 1.5 ratio. E-type channels are typically considered a stable stream form. However, these streams are sensitive to disturbance, especially in soils with low cohesion, and may rapidly degrade to unstable G and F-type channels. To better understand the existing condition of the project reach, qualitative stability assessments of distinct stream sections were developed based upon measured stream dimensional characteristics (i.e., entrenchment ratio, bank height ratio) and visual observations utilizing the Pfankuch Channel Stability and Rosgen Bank Erosion Hazard Index (BEHI) methodologies. These evaluations confirm that both streams are in a poor state of stability and exhibit high potential for continued bank erosion (See Appendix B). The impacts associated with unrestricted cattle access to the stream and the absence of riparian and bank vegetation are the most significant factors contributing to stream degradation on site. Grazing of livestock near stable streams generally leads to channel adjustments including increases in bank erosion, sediment supply, and width-to-depth ratio. On site, hoof shear and a lack of sufficient stabilizing vegetation have resulted in a high rate of bank erosion and collapse. 8 Lick Creek Stream Restoration Plan Lee County, North Carolina This bank instability has begun the process of incision, over-widening, and straightening to varying degrees. The large amount of fine-grained particles contributed by the eroding banks is causing excessive sediment accumulation and channel aggradation that only exacerbates the tendency for the hydraulically inefficient channels to over-widen. This silt and sediment buildup appears to be the main aquatic habitat limiting factor as it clogs the substrate and creates conditions unsuitable to support diverse bivalve, benthic macroinvertebrate, and fish habitat. It is important to consider this process of channel evolution where incision, widening, and aggrading is occurring when evaluating the potential of the existing degraded channel to naturally stabilize over time. Without intervention, it is expected that bank materials will continue to erode at an accelerated rate - a process that is likely to be exacerbated by flow regime alterations that will occur in response to pending watershed development. The channels are expected to continue degrading, causing the stream to migrate from a degraded E-type to an incised G-type or a further overwidened F-type stream. 3.4.3 Stability Assessment The current "stream state or condition" (Rosgen 1996) was further analyzed using Rosgen Level III methodologies to assess stability through an examination of parameters such as channel dimension (W/Dsite compared with W/Drefe?ence), vertical stability (Bank Height Ratio), lateral stability (BEHI), and sediment supply/transport. In the project reach, comparisons of the existing width-to-depth ratio values to the reference reach width-to-depth ratio values vary slightly and bank height ratios in this section ranged from 1.0 to 1.3. However, Bank Erosion Hazard Index (BEHI) scores ranged from 39.2 to 39.8, indicating a high potential for continued bank erosion and channel widening in the upper project reach. Additionally, sediment supply is high from severely eroding banks. The existing channel is slightly entrenched and exhibits long straightened reaches, lack of appropriate riffle-pool sequencing, and insufficient pool depth. Collectively, these factors indicate both vertical and lateral instability through channel incision and widening, respectively, in this portion of the project reach. 3.4.4 Bankfull Verification The accepted methodology for natural channel design is based on the ability to select the appropriate bankfull discharge and generate the corresponding bankfull hydraulic geometry from a stable reference reach. Thus, the determination of bankfull stage is the most critical component of the natural channel design process. Observable bankfull stage indicators in North Carolina include the incipient point of flooding (top of bank), upper breaks in bank slope, the back of the highest depositional feature (i.e. point bars and benches), and the highest scour line. At the project reach, the most consistent field indicator of bankfull stage proved to be a discernable change in bank slope aspect. Photographs of typical bankfull indicators and related morphological features at the project site are provided in Figure 7 (Bankfull Indicators). The identification of bankfull stage can be problematic, especially in a degraded system. Therefore, verification measures must be taken to ensure the accurate identification of the bankfull stage. The field indicated bankfull stage was verified using a combination of tools and data, including regional hydraulic geometry relationships (regional curves) (Harmon et al 1999). 9 Lick Creek Stream Restoration Plan Lee County, North Carolina The bankfull cross-sectional areas for the project reach were consistent with the cross-sectional area regressed power function lines from the regional curve, plotting within the 95 percent confidence limits (Figure 8: NC Rural Piedmont Regional Curve). 3.5 CONSTRAINTS The presence of any constraints that have the potential to hinder restoration activities at the project site were evaluated. This evaluation focused primarily on the presence of hazardous materials, ' utilities, restrictive easements, RTE species or critical habitats, cultural resources, and the potential for hydrologic trespass as well as any site conditions that have the potential to restrict the restoration design and implementation. ' The restoration design was required to incorporate the presence of structural requirements associated with the Lower Moncure Road Bridge over Wallace Branch. The 50-foot right-of-way, which contains a subsurface water line, dictated limitations in stream planform adjustment and ' riparian revegetation parameters. No other conditions, natural or man-made, were identified as having the potential to impede the ' proposed restoration activities. 10 Lick Creek Stream Restoration Plan 4.0 METHODOLOGY Lee County, North Carolina Information and techniques on stream classification and morphology from Applied River Morphology by Rosgen (1996) was used for classifying the stream and reference reaches. For this restoration plan, the existing conditions of the stream and surrounding area were first observed and recorded in order to understand what was occurring within the system. This enabled the development of a plan that focuses on the restoration of the entire system. Information was collected on existing conditions, reference conditions, and proposed conditions for the stream and buffer restoration areas. 4.1 STREAM CLASSIFICATION Information on stream morphology and classification from Applied River Morphology (Rosgen 1996) was used to evaluate and classify the stream. Several data are needed in order to classify a stream, including width-to-depth ratio, entrenchment ratio, slope, sinuosity, and dominant type of channel material. All five of the criteria are interrelated and used to determine the current condition of the channel, classify the stream, and aid in the design process. Width-to-depth ratio is the ratio of the bankfull width to the mean depth of the bankfull channel. The width-to-depth ratio indicates the channel's ability to dissipate energy and transport sediment. The entrenchment ratio is the vertical containment of the stream and the degree to which the channel is incised in the valley floor. The entrenchment ratio is an expression of the stream's ability to access its floodplain. The flood-prone width divided by the bankfull width yields the entrenchment ratio. The slope is the change in water surface elevation per unit of stream length. The slope can be analyzed over the entire reach, to determine if the slope is stable within the existing channel material, or over sections, to determine the condition of pools and riffles. Sinuosity is the ratio of stream length to valley length. Extremely low sinuosity channels in the Piedmont of North Carolina typically indicate a straightened channel. Channel bed and bank materials indicate the channel's resistance to hydraulic stress and ability to transport sediment (Rosgen 1996). Elevation measurements for the longitudinal profile survey as well as pool and riffle cross-sections included, but were not limited to: ¦ thalweg ¦ top of low bank ¦ edge of water ¦ terrace ¦ water surface ¦ width (bankfull, top of channel, flow) ¦ bankfull ¦ depth (mean, bankfull, max). Measurements were also taken for the following: ¦ bank slope ¦ straight length ¦ width of flood prone area ¦ pool-to-pool spacing ¦ belt width ¦ bankfull area ¦ valley length ¦ composition of channel materials. These measurements were used to classify the stream and are used in the design process. Once these parameters were known, a design was proposed based on the geomorphic processes occurring with the channel. The survey also identified design constraints of the site (e.g., roadways, culverts, and bridges). 11 Lick Creek Stream Restoration Plan" Lee County, Carolina 4.2 SEDIMENT TRANSPORT ANALYSIS The stream's ability to transport the sediment load without aggrading or degrading is the threshold of the stream's stability. This stability is evaluated through an evaluation of channel competency. Competency is the channel's ability to move particles of a certain size, expressed as units of pounds per square foot. Shear stress is the force required to initiate the general movement of particles in a streambed. This entrainment of particles must be of sufficient force to move the largest particle from the bar sample (Di) to prevent aggradation of particles. In order to move the D, particle, the stream design ' must meet a critical depth and slope. The shear stress analysis indicates whether a stream has the ability to move its bedload. To validate this theory-based explanation, shear stress was calculated for the design rife cross- sections in both the upper and lower project reaches using the equation: i = yRs Where:ti = shear stress (Ibs/ft2) y = specific gravity of water (62.4 Ibs/ft) R = hydraulic radius (ft) f s = average water slope (ft/ft) ¦ 4.3 DISCHARGE ANALYSIS The methodology used to evaluate the hydrologic analysis required the evaluation of the existing stream's bankfull discharge. The bankfull discharge was determined by evaluating the North Carolina Rural Piedmont Discharge Curve (Harmon et al 1999). r 4.4 BIOTIC SURVEY A survey of the biotic community was conducted prior to restoration. The survey of the existing reach included observation of aquatic species, terrestrial wildlife, and plant communities. The post-construction stream survey will also include those items. This information assists with development of the restoration plan and will provide evidence for measuring the successfulness of the Restoration Project. 12 Lick Creek Stream Restoration Plan 5.0 REFERENCE REACH ANALYSIS Lee County, North Carolina A reference reach is a channel with a stable dimension, pattern, and profile within a particular valley morphology. The reference reach is used to develop dimensionless morphological ratios (based on bankfull stage) that can be extrapolated to disturbed/unstable streams to restore a stream of the same type and disposition as the reference stream (Rosgen 1998). The reference reach search encompassed the entire Triassic Basin within North Carolina. Of the candidate streams examined, only two streams located in Anson County, North Carolina, had stable banks, the correct substrate, valley type, and slope to be considered appropriate reference reach streams for this project. The streams are referred to as unnamed tributary (UT) to Reedy Creek Mainstem and UT to Reedy Creek Tributary. 5.1 UT TO REEDY CREEK MAINSTEM REFERENCE REACH A stable section of a UT to Reedy Creek Mainstem, a second order stream that flows south into Reedy Creek, was selected as a reference reach for the project (Figure 9: Reference Reach Location Map). Approximately 232 linear feet (15 bankfull widths) of the UT to Reedy Creek were surveyed in February 2005. The selection of this reach was based on its location in the same hydrophysiographic province, similar watershed position and land use, and similar sediment regime as the project site. Likewise, the valley slope (0.6 percent compared to 0.8 percent) and sediment distribution (D50 of five mm compared to four mm) of the reference site were very similar to that of the project site. The UT to Reedy Creek reference reach was classified as a E4 stream type. Collected morphological data as well as representative photographs of the reference site are provided in Appendix C and Appendix D. The measured morphological variables and dimensionless hydraulic geometry relationships developed to facilitate the restoration design are provided in Section 6. 5.2 UT TO REEDY CREEK TRIBUTARY REFERENCE REACH In addition to the aforementioned reference reach, a tributary to the mainstem UT was also surveyed and evaluated as supporting data for the stream design in February 2005. Approximately 109 linear feet (16 bankfull widths) of the tributary was surveyed. The selection of this reach was based on its location as a contributing tributary with similar watershed position, land use, similar sediment regime, valley slope (0.6 percent compared to 0.9 percent) and sediment distribution (D50 of 1.1 mm compared to four mm) to that of the project site. The tributary reference reach was classified as an E5 stream type. Collected morphological data as well as representative photographs of the reference site are provided in Appendix C and Appendix D. The measured morphological variables and dimensionless hydraulic geometry relationships developed to facilitate the restoration design are provided in Section 6. 13 Lick Creek Stream Restoration Plan 6.0 STREAM RESTORATION DESIGN 1 6.1 PROPOSED CONDITIONS FOR NATURAL CHANNEL DESIGN Lee Countv. North Carolina The restoration design of Wallace Branch and Lick Creek is based on a Priority Level 1 approach, as described in "A Geomorphological Approach to Restoration of Incised Rivers", (Rosgen 1997). For clarity and convenience, the definition of Priority 1 Restoration is provided in Table 2. Table 2. Priori 1 Level Restoration 1 "Adapted from Rosgen (1997), "A Geomorphological Approach to Restoration of Incised Rivers". Description Methods Advantages Convert G, F and ¦ Reestablish channel on previous floodplain Reestablishment of floodplain and degraded E/C using relic channel or construction of new stable channel: stream types to C bankfull discharge channel. ¦ reduces bank height and or E stream types ¦ streambank erosion at previous ¦ Design of stable dimension, pattern, and ¦ reduces land loss elevation with profile based upon morphological criteria ¦ raises water table floodplain. developed from reference reach with similar ¦ reconnects stream to floodplain watershed, valley, land use, and sediment providing flood attenuation supply. ¦ decreases sediment ¦ ¦ improves aquatic and terrestrial ¦ Fill in existing incised channel or create habitats discontinuous oxbow lakes level with new ¦ improves land productivity flood lain elevation. ¦ improves aesthetics The design proposes constructing 9,500 linear feet of meandering channel. Based upon existing stream and valley characteristics, a Priority Level 1 restoration approach, as generally defined in Table 2, will be used to restore stable E4 stream channels. The restoration will establish a bankfull channel with a native floodplain at bankfull elevation and the dimension necessary to provide stable flow maintenance and sediment transport. The design bankfull stage will approximately equal the floodplain elevation in the new channel (bank height ratio = 1.0). The proposed stream dimension, pattern, and profile will be based on the detailed morphological criteria and hydraulic geometry relationships developed from the reference reach stream (Table 3). The establishment of a stable bedform (i.e., riffle-pool sequence, pool spacing) will be addressed in the profiling of the design channel. Refer to Figures 10 and 11A-F (Typical Cross-Sections and Restoration Plan and Profile Sheet) for the proposed channel dimension, pattern and profile. Various in-stream structures will be incorporated in the stream design to reduce the burden of energy dissipation on the channel geometry (Figure 12: Details: Typical In-stream Structures). These structures are designed to reduce bank erosion and the influence of secondary circulation in the near-bank region of stream bends. The structures further promote efficient sediment transport and produce or enhance in-stream habitat. Cross-vanes will serve as grade control in the restored channel. Biodegradable coir fiber matting will be used to provide temporary stabilization on the newly graded streambanks as well as planting of temporary seed mixtures. The confluence of tributaries with the restored stream will be stabilized with grade control structures and step sequences, where necessary, to match the proposed grade of the restored main channel. Excavated materials from the design channel will be used to backfill the abandoned channel sections. However, shallow linear depressions (oxbows) within the existing channel belt width may be incorporated to provide additional flood storage and valuable aquatic habitat in the floodplain. 14 Lick Creek Stream Restoration Plan Lee County, North Carolina Cattle exclusion fencing will be installed along the outer boundary of the restored riparian buffer/permanent conservation easement area. This will prevent continued bank erosion and collapses caused by hoof shear, as well as eliminate cattle excrement and resulting fecal coliform loading. A limited number of stabilized, rock ford stream crossings will be installed to provide cattle access to isolated pasture areas. These crossing points will be fenced on both sides utilizing standard Natural Resources Conservation Service (NRCS) water gate designs to prevent cattle from further accessing the stream and riparian buffers. 6.1.1 Proposed Channel Description and Stream Classification The proposed channel is a stable E4 channel. As previously discussed, the existing channel contains minimal pattern, profile, or dimension variation. The proposed stream pattern utilizes existing meanders where feasible and enhances sinuosity in segments that have been straightened. The proposed pattern will be further enhanced by a more effective profile form. Riffles, runs, pools, and glides will oscillate with the meanders providing energy dissipation. Furthermore, the dimension will alter from a typical riffle through the run into the pool cross-section and again from the pool through the glide into the riffle cross-section. The channel will access the floodplain more efficiently in the proposed design to reduce stress on the streambanks. E4 channels with appropriate dimension, pattern, and profile form as well as the ability to access the floodplain are efficient and stable channels. 6.1.2 Sediment Transport A stream's ability to transport its sediment load without aggrading or degrading is a primary indicator of the stream's stability. Therefore, an analysis of shear stress has been conducted to assess the proposed design's stability. The D50 for the existing stream is four millimeters, thus the allowable shear stress is in the 0.04 - 0.07 lbs/ft2 range. Each reach of the proposed design falls within this range. Reach A will require several grade control structures (four drops at a half foot each) to decrease the riffle slopes to achieve suitable shear stress. 6.1.3 Structures Used for Natural Channel Design A number of different structures and methods will be used to control grade and stabilize the channel. These structures and methods may include, but are not limited to rock cross-vanes, rock vanes, log vanes, j-hook vanes, root wads, floodplain interceptors, matting, and planting' materials. These structures provide grade control and bank stabilization such that the proper dimension, pattern, and profile are maintd'hed while providing various habitats for aquatic organisms. The structures provide a substrate for benthic macroinvertebrates to feed on, hide under, and attach. They also provide shelter and create eddies for fish to rest and feed near. The majority of the materials for the structures will come from off site. Diagrams of these structures are located in Figure 12 (Details: Typical Structures). Rock cross-vanes, rock vanes, log vanes, and j-hook vanes will be utilized to direct the flow away from the bank and toward the center of the channel. Rootwads will be used for bank stabilization and to introduce woody material into the channel. Without this introduction it would be many years before the planted saplings would be able to provide the stream with this habitat feature. Rock Cross-Vanes - Rock cross-vanes direct the flow away from the streambanks into the middle of the channel. The structure creates a scour pool below, while maintaining the grade for the upstream reach. These structures will also provide a stable drop in the stream profile. Boulders 15 I 1 I Lick Creek Stream Restoration Plan Lee Countv. North Carolina are used to build these structures and filter fabric and smaller rock will be used to further strengthen it by solidifying gaps between the boulders. Rock or Log Vanes - Vane structures direct the flow away from the streambank and into the center of the channel. The vane structure creates a scour pool immediately downstream which provides a habitat feature. Rock vane structures will be built with boulders and will be used on the outside of meander bends. Log structures may be utilized with approval from the engineer and will be used on the outside of meander bends in similar fashion to the rock vane structures. J-Hook Vanes - J-Hook vanes are built with boulders and placed in the stream to direct flow away from the streambanks. The structure has the appearance of a "J" since it consists of one rock vane with boulders placed in the center of the channel curving back around to form a hook. In addition to the vanes scour pool, the openings between the extra boulders create a variety of flow patterns. Fish often hold in the calm water behind the boulders to catch food flowing flow patterns around the bounders. Rootwads - Rootwads will be utilized for streambank protection, habitat for fish, habitat for terrestrial insects, cover, and introduction of woody material into the stream. Rootwads act as a deflection device to the stream's flow. The roots buffer the streambank and aid in deflecting the stream's erosive forces away from the streambank. Floodplain Interceptor - Floodplain interceptors will provide water on the floodplain with a stabilized access point to flow back into the channel. The floodplain interceptors shall be placed in low swale type areas on the floodplain where floodwater is expected to re-enter the stream channel. Matting and Planting - Matting, live staking, and vegetation planting will be utilized to stabilize the project. Matting will provide immediate protection to the streambanks while the plantings develop a root mass and aid in protecting against shear stress. Vegetation transplanting may be used. The plantings will develop into mature trees that will be capable of providing the stream with shade and wildlife habitat. The streambed and point bars of the stream channel will not be matted or planted. The detailed planting plan is discussed in Section 7.2. 16 m W co ? y o m o_ y O o O• 7 v ?

This is a multi-step process involving site preparation (including eradicating exotic species), acquisition and installation ' of appropriate plant species, and post-project monitoring. Effective riparian buffers provide perennial root systems for soil stabilization and long-term nutrient storage for pollutant control. 7.1 ERADICATION OF EXOTIC SPECIES Prior to the revegetation phase of the project, non-native floral species must be removed. Exotic species currently identified within the project area include Chinese privet and Japanese honeysuckle. Invasive species eradication and management will begin during the site preparation stage and continue through the five-year monitoring period at a minimum. Management ' procedures described below are based upon recommendations taken from the Southeast Exotic Pest Plant Council Invasive Plant Manual (SE-EPPC 2003). Personnel applying herbicide will be licensed to do so, as required by the North Carolina Pesticide Board. All work will comply with the North Carolina Pesticide Law of 1971 and applicable federal laws (G.S. 143-434, Article 52). Environmental conditions including weather, wind, temperature, and period of the growing season will be evaluated prior to initiation of management efforts. The ' sequence of removal procedures will be coordinated with planned seeding and planting tasks such that treatment methods do not affect planted species. ' The first step of the invasive species removal process will consist of an application of Rodeo® or equal herbicide (glyphosate - aquatic label) designated as suitable for extermination of trees and shrubs in riparian and wetland areas. Ideally, application will occur late in the growing season, but ' prior to dormancy. Ambient air temperature at the time of application will be above 40°F. The herbicide will be applied at the recommended rate in accordance with label instructions. This application will be completed a minimum of two weeks prior to planting activities. The herbicide will ' be applied on all identified invasive plants using appropriate application methods to prevent drift into adjacent areas. Two weeks after spraying, all woody vegetation will be removed by cutting stems and stumps to a ' maximum height of two inches above ground. A 25 percent glyphosate herbicide solution approved for aquatic applications shall be immediately applied to completely cover the cut surface of each individual stem or stump. After an additional two week period, woody remnants will be removed, separated from the soil, and disposed of properly (i.e. burning). The site shall be observed throughout the monitoring period to evaluate invasive management effectiveness. If required, additional control steps may be implemented. ' 18 Lick Creek Stream Restoration Plan Lee County, North Carolina 7.2 PLANTING PLAN Native woody and herbaceous species will be used to establish a minimum 50-foot wide riparian buffer on both sides of the restored reach. In some areas the buffer will extend beyond 50 feet as the riparian buffer plantings will encompass the entire conservation easement. The stream design will take into account the necessary 50 foot buffer and top of bank will be no closer than 50 feet from the edge of the easement. The buffer area adjacent to the stream reach has been divided into four zones as follows: ¦ Streamside ¦ Lower Floodplain ¦ Upland Slope ¦ Pocket Wetlands Species selected for planting will be dependent upon availability of local seedling sources, but may consist of those listed below. Advance notification/coordination with local nurseries (one year) will facilitate availability of various non-commercial elements. The proposed plantings will cover the constructed streambanks, floodplain, and constructed wetland areas (Tables 4, 5, 6, and 7). Throughout the majority of the site, the target natural community will be a Piedmont/Mountain Bottomland Forest. Where the project area encompasses portions of upland slopes adjacent to the floodplain areas, limited to a minor area on the southern bank of Wallace Creek upstream of the Lower Moncure Road crossing, the target community will be a Mixed Mesic Hardwood Forest. In some areas, remnants of the target natural communities currently exist with mature individuals of the desired species. As much as possible in these areas, the zone of construction activity will be limited to lessen damage to individual stems. Maintaining existing trees in place with intact root masses will contribute to post-construction slope soil and streambank retention. Areas with existing tree canopy will receive primarily herbaceous and shrub plantings. Where opportunities exist to transplant existing trees for revegetation, those individuals will be moved to new positions along the constructed stream section. Individuals considered candidates for transplanting should not be larger than 1.5 inches in diameter at breast height (dbh). Bare-root seedlings for each planting zone (Tables 4, 5, 6, and 7) will be planted at random intervals within the specified areas at a density of 436 stems per acre (based on an average ten- foot by ten-foot spacing) to achieve a mature survivability of 320 trees per acre within the riparian buffer (NCDENR, 2001 b). To provide structural diversity, native shrubs will also be incorporated in the buffers at a density of 681 stems per acre. Shrubs will typically be installed in small groupings of two to three individuals, with overall placement of both the individual stems and the groupings to be randomized in order to develop a more naturalized appearance in the buffer zones. On the restored streambanks (Table 4), live stakes and/or bare root seedlings will be used in conjunction with the native herbaceous seed mix to provide natural stabilization. Live stakes or seedlings will be placed on the outside of meander bends at a density of two to four stakes per square yard and in random fashion to give a natural appearance. Woody vegetation planting will be conducted during dormancy. Plant placement will be further defined during the design process. Herbaceous vegetation seeded within the buffer shall consist of a mixture of three native species that the contractor will select from the Table provided for that planting zone. In addition, rye grain 19 Lick Creek Stream Restoration Plan Lee County, North Carolina (Secale cereale) or pearl millet (Pennisetum glaucum) will be used for temporary stabilization, depending upon the construction season and schedule. The following planting zones and species have been identified for the project: Table 4.

North Carolina Pocket wetlands will be created by excavating shallow pools in the floodplain and by using the existing agricultural ditches and areas of the relic channel after the new channel is constructed. Benefits of pocket wetlands include providing added water quality benefits by treating some of the stormwater runoff from the agricultural fields, floodwater retention, and providing more diversity of habitat for insects, amphibians, and birds along the project reach. The wetland areas will be planted with species listed in Table 7. Herbaceous vegetation seeded in these areas will be a mixture of three native species that the contractor will select from Table 7. In addition, rye grain or pearl millet will be used for temporary stabilization, if needed. ' 7 22 Lick Creek Stream Restoration Plan Lee County, North Carolina 9.0 MONITORING AND EVALUATION Monitoring protocol will follow that outlined within the EEP Site Specific Mitigation Plan and detailed in the U.S. Army Corps of Engineers (USACE) Stream Mitigation Guidelines for Monitoring Level I. Monitoring shall consist of the collection and analysis of stream stability and riparian/stream bank vegetation survivability data to support the evaluation of the project in meeting established restoration objectives. Specifically, project monitoring will include measurements of stream dimension/profile/pattern/bed materials, photo documentation, vegetation survivability sampling, and stream bankfull return interval. 9.1 DURATION Monitoring shall be conducted annually for a minimum of five years or until success criteria are met, as required in the guidelines and called for in the contract agreements. The first scheduled monitoring event will be conducted at the end of the first full growing season following project construction and planting. 9.2 REPORTING A monitoring report will be prepared after all monitoring tasks for each annual monitoring event are completed. Each report will provide the new monitoring data and compare the new data against previous findings. Data tables, cross-sections, profiles, photographs, and other graphics will be included in the report as necessary. Each report will include a discussion of any significant deviations from the as-built survey and previous annual measurements, as well as evaluations as to whether the changes indicate a stabilizing or de-stabilizing condition. Each annual monitoring report will be submitted by December 31 of the year during which the monitoring event was conducted. 9.3 STREAM STABILITY The purpose of monitoring is to evaluate the stability of the restored stream. Following the procedures established in the USDA Forest Service Manual (Harrelson et al 1994) and the methodologies utilized in the Rosgen stream assessment and classification system (Rosgen 1994, 1996), data collected will consist of detailed dimension and pattern measurements, a longitudinal profile, and bed materials sampling. 9.3.1 Dimension Permanent cross-sections (one per 20 bankfull-width lengths, evenly divided based upon riffle and pool percentages), will be established and used to evaluate stream dimension. At least one riffle and one pool cross-section will be located within the area also surveyed as part of the longitudinal profile. Permanent monuments, recoverable either through field identification or use of GPS, will be established at the left and right extents of each cross-section. The cross-section surveys shall provide a detailed measurement of the stream and banks, to include points on the adjacent floodplain, at the top of bank, bankfull, at all breaks in slope, the edge of water, and thalweg. Subsequently, width-to-depth ratios, entrenchment ratios, and bank height ratios will be calculated for each cross-section. Cross-section measurements should indicate little change from the as-built cross-sections. If changes do occur, they will be evaluated to determine whether they are adjustments associated 23 1 ' Lick Creek Stream Restoration Plan Lee County, North Carolina with settling and increased stability or whether they indicate movement towards an unstable condition. 9.3.2 Pattern ' Evaluations of stream pattern, based on valley/stream type, will be developed based upon measurements of sinuosity, meander width ratio, and radius of curvature (on newly constructed meanders only for first year monitoring). Calculations will be made of sinuosity, meander width ' ratio, radius of curvature/bankfull width ratio, and meander length/bankfull width ratio. Measurements and calculated values should indicate stability with little deviation from as-built conditions and established morphological ranges for the restored stream type. 9.3.3 Profile Three longitudinal profiles, each covering 20 bankfull-width lengths, will be established and surveyed. The first monitored longitudinal profile will cover a portion of the restored section of Wallace Branch, upstream of its confluence with Lick Creek. The second monitored longitudinal profile will cover a portion of the restored section of Lick Creek, upstream of its confluence with Wallace Branch. The last monitored longitudinal profile will cover a portion of the restored section of Lick Creek located between its confluence with Wallace Branch and the downstream project ' limits. The beginning and ending points of each measured section will be permanently monumented. Average, pool, and riffle slopes, as well as pool-to-pool spacing will be calculated. ' Annual measurements should indicate stable bedform features with little change from the as-built survey. The pools should maintain their depth with flatter water surface slopes, while the riffles should remain shallower and steeper. t 9.3.4 Bed Materials Pebble counts will be conducted at each cross-section, as well as across the overall study reach (based upon percentage of riffles and pools) for the purpose of classification and evaluation of sediment transport. Pebble count data will be plotted by size distribution in order to assess the D50 and D85 size class. Calculated Dw and D85 values should indicate coarser size class distribution of bed materials in riffles and finer size class distribution in pools. ' 9.4 PHOTOGRAPH REFERENCE POINTS ' Photograph reference points (PRPs) will be established to assist in characterizing the site and to allow qualitative evaluation of the site conditions. The location of each photo point will be permanently marked in the field and the bearing/orientation of the photograph will be documented to allow for consistent repetition. 9.4.1 Cross-Section Photograph Reference Points A photograph will be taken at each permanent cross-section established. The photograph will be taken from a point located upstream of the cross-section looking downstream, and will show as much of the banks and channel as possible. The survey tape used for cross-sectional ' measurements will be centered in each photograph and the water line will be located near the ' 24 Lick Creek Stream Restoration Plan Lee Countv. North Carolina lower edge. An effort will be made to consistently photograph the same area in each subsequent monitoring event. 9.4.2 Longitudinal Photograph Reference Points A maximum of twenty additional PRPs will be established along the restored stream to allow further documentation and qualitative evaluation of the channel condition. 9.4.3 Additional Photograph Reference Points Additional PRPs will be established, as needed, to allow documentation and qualitative evaluation of the condition of specific in-stream structures such as cross-vanes, J-hook vanes, and rootwads. 9.5 BANKFULL HYDROLOGY Monitored stream flow data will be used to evaluate the success of restoring the intended bankfull return period. Four stream gauges will be used for monitoring flow stage within the restored reaches: one each at the upstream limits of Lick Creek and Wallace Branch, one at the confluence of the streams, and one at the downstream limits of Lick Creek. Monitored data and calculated return intervals should indicate the occurrence of a bankfull event during a minimum of two of the five monitored years. 9.6 VEGETATION MONITORING The survivability of the riparian buffer plantings will be evaluated using a sufficient number of randomly placed tenth-acre vegetative sampling plots to provide combined sample coverage of two percent of the replanted area. The corners of each monitoring plot will be marked in the field and their position documented by either conventional survey or GPS. The monitoring will consist of a physical inventory within each plot in order to determine the composition and number of surviving species and the total number of stems per acre. To the extent possible, differentiation between planted and volunteer stems will be accomplished. The presence of non-native, exotic, and undesirable species will be noted. Additionally, sequential photographs will be taken from the center of. each monitoring plot, starting at due north, to create a 360-degree view of the sample site. Riparian vegetation monitoring shall be conducted for a minimum of five years to ensure that success criteria are met per USACE guidelines. If monitoring indicates either that the specified survival rate is not being met or the development of detrimental conditions (i.e., invasive species, diseased vegetation), appropriate corrective actions will be developed. 25 ' ' Lick Creek Stream Restoration Plan Lee County, North Carolina 10.0 REFERENCES Griffith, G.E., Omernik, J.M., Comstock, J.A., Schafale, M.P., McNab, W.H., Lenat, D.R., MacPherson. 2002.
