EMMNW4? wwmwi? ?? ?? NEMNMEWO? KCI TECHNOLOGIES Joseph J. Pfeiffer, Project Manager jpfeifferA,kci.com 919-783-9214 June 2006 I lilu,, Executive Summary The Brown Farm Wetland Restoration proposes to improve water quality and expand wetland habitat by restoring agricultural land to a functioning riverine wetland ecosystem. Currently, the site is used for harvesting hay and occasional grazing and is located directly within the floodplain of New Hope Creek in the Cape Fear Basin. This important water body contains unique aquatic habitat both upstream and downstream of the project site. The project will restore 24.58 acres of wetland and enhance 3.32 acres of existing wetlands along the New Hope Creek Corridor. The Brown Farm is adjacent to New Hope Creek in Durham, North Carolina along the Orange-Durham County Line. The site drains into New Hope Creek to the east, which then flows approximately 11 miles before entering Jordan Lake. The project has a contributing drainage area of 33.33 square miles (21,331 acres) at the downstream limits of the site. New Hope Creek is listed as an impaired water body under the - draft 2004 303(d) list for North Carolina starting approximately 2.4 miles downstream of the project site at the confluence with Sandy Creek. This segment of stream has impaired biological integrity from urban runoff and storm sewers. Historic aerial photographs dating from 1955 show the site under cultivation or in pasture in recent years. Currently, the project watershed is approximately 83% forested based on the North Carolina GAP land use classification, but the surrounding area continues to experience rapid growth. Downstream and outside of the project watershed, there is residential and commercial development expanding along the North Carolina State Highway 15-501 corridor to the east. The Orange and Durham County Soil Surveys classify the soils at the site as primarily Chewacla with some Wehadkee. The county soil survey classifications, however, were not fully consistent with the conditions observed on-site by a KCI soil scientist. A detailed soils investigation was conducted across the site and the resulting distribution of soils at the Brown Farm is estimated to be 75% Wehadkee and 25% Chewacla. The Wehadkee and Chewacla soils are defined as hydric soils due to saturation for a significant period during the growing season. The project site is located on an expansive, active floodplain of New Hope Creek. Moving west from the stream, the site slopes downward at approximately 1% from the levee position of the creek to a lower floodplain position in the center of the site. This central portion is flat extending to the north, south and west to the valley walls on the site. Existing wetlands were delineated in August 2005 using the methods described by the US Army Corps of Engineers. There are 3.32 acres of jurisdictional wetlands on the property. There are no streams that flow directly through the project site. Upper New Hope Creek forms the eastern boundary of the project and the entire site eventually drains to this strearn. There is a series of major and minor drainage ditches that run along and throughout the site. The landowner states that some of the larger ditches have been in place since the 19`" century. Smaller minor ditches are distributed throughout the site at approximately 50 feet apart. This extensive ditch network reduces the amount of total hydrologic input that can remain on-site. A reference wetland was found approximately 0.8 miles from the Brown Site and was used to guide the restoration design. It is also within the floodplain of New Hope Creek and is downstream from the project site. The property is owned by the County of Durham and is included in a larger area of land protected as the New Hope Creek Bottomlands. The composition of plant species at the reference wetland is best described as a Piedmont Bottomland Hardwood Forest. Using the reference wetland and existing site conditions, a restoration design was developed for the Brown Farm. Current pastureland with drained hydric soils will be restored to wetland. Existing wetlands will be enhanced by improving the hydrology and vegetation. Surrounding upland areas on the site will be included to recreate a functioning ecosystem. Hydrologic modifications will focus on restoring historic wetland hydrology by removing ditches and berms that restrict flow from remaining on-site. Three level spreaders will also be constructed to reconnect the hydrology across the entire site. These features will spread across the site in several places and are designed to mimic the natural, elongated flowpath in a wetland. In order to block the remaining flow from leaving via minor ditches that run primarily northwest to southeast, wetland microtopography will be oriented perpendicular (i.e. southwest to northeast). This grading method will effectively create small depressions and rises across the landscape while stopping the flowpath from these ditches. Using this procedure will also allow some of the existing grasses to remain in place to stabilize the system. The restoration of natural vegetation will focus on establishing native wetland hardwood species in the entire wetland. The majority of the area will receive species consistent with a Piedmont Bottomland Hardwood Forest community. Enhancement areas will be planted with targeted hardwood species to increase species diversity. One section of the enhancement area is a Floodplain Pool community and will be planted as such. Populations of invasive species have also been identified and will be eliminated as much as possible. A monitoring program will be implemented to observe the progress toward achieving mitigation goals and objectives within the restored wetland areas. The site will be deemed successful once wetland hydrology is established and vegetation success criteria are met. Management activities will be conducted as necessary to control invasive species or handle other issues as they arise. The restoration of the Brown Farm to a functioning wetland will allow the site to retain a greater amount of floodwaters from New Hope Creek. The wetland will also provide water quality benefits by acting as a buffer to New Hope Creek from upstream agricultural and residential uses. These restoration activities will reduce both point and non-point source pollutants to the system and improve aquatic and terrestrial habitat along the New Hope Creek Corridor. 11 BROWN FARM RESTORATION PLAN TABLE OF CONTENTS INTRODUCTION- 1.0 PROJECT SITE IDENTIFICATION AND LOCATION ................... 1.1 Directions to Project Site ................................................................. 1.2 USGS Hydrologic Code and NCDWQ River Basin Designations.. 2.0 WATERSHED CHARACTERIZATION ............................................ 2.1 Drainage Area .................................................................................. 2.2 Surface Water Classification / Water Quality ................................. 2.3 Physiography, Geology and Soils .................................................... 2.4 Historical Land Use and Development Trends ................................ 2.5 Endangered / Threatened Species .................................................... 2.6 Cultural Resources ........................................................................... 2.7 Potential Constraints ........................................................................ 3.0 PROJECT SITE WETLANDS ............................................................ 3.1 Jurisdictional Wetlands .................................................................... 3.2 Hydrological Characterization ......................................................... 3.3 Sol] Characterization ....................................................................... 3.4 Plant Community Characterization ................................................. 4.0 REFERENCE WETLANDS ................................................................ 4.1 Hydrological Characterization ......................................................... d 7 Qnil ( hnrnrtnrivntinn 4.3 Plant Community Characterization ................................................. 5.0 PROJECT SITE RESTORATION PLAN ........................................... 5.1 Restoration Project Goals and Objectives ....................................... 5.2 HEC-RAS Analysis ......................................................................... 5.3 Hydrological Modifications ............................................................. 5.4 Natural Plant Community Restoration ............................................ 6.0 PERFORMANCE CRITERIA ............................................................. 6.1 Hydrology ........................................................................................ 6.2 Vegetation ........................................................................................ 6.3 Schedule / Reporting ....................................................................... 7.0 REFERENCES .................................................................................... 4 4 6 6 7 7 7 ... 13 ... 14 ... 15 ... 15 ... 15 ... 20 ... 20 ... 20 ... 23 ... 24 ... 26 ... 28 ... 28 ... 28 ... 29 ... 30 iii FIGURES Figure 1.

Using results from field studies and a literature review, this document provides an overview of the planned restoration project. The hydrology, soils, and vegetative communities at a nearby reference wetland are included and will serve as a model to shape the final restoration design. Once completed, the project will add another piece to the protected areas along the New Hope Creek Corridor. 1.0 PROJECT SITE IDENTIFICATION AND LOCATION • 1.1 Directions to Project Site The Brown Farm Site is located adjacent to New Hope Creek and is approximately two miles west of Durham, North Carolina along the Orange-Durham County Line as seen in Figure 1. The site is approximately one mile east of the intersection of Erwin Road and Mt. Moriah Road and is located on • United States Geologic Survey (USGS) Southwest Durham and Chapel Hill Quadrangles. The project site is approximately located at 35.9670 N Latitude and 78.9977 W Longitude (WGS 1984). 1.2 USGS Hydrologic Code and NCDWQ River Basin Designations The property is in the 03030002 (Upper Cape Fear 02) Watershed Cataloging Unit (8-digit HUC) and the 03030002060110 (Upper New Hope Creek) Local Watershed Unit (14-digit HUC). The site drains into New Hope Creek to the east, which then flows approximately 11 miles before entering Jordan Lake. In the North Carolina Ecosystem Enhancement Program's (EEP) Cape Fear River Basin Watershed Restoration Plan, the Upper New Hope Creek Watershed (03030002060110) has been identified as a high priority Targeted Hydrologic Unit/Watershed. • 2.0 WATERSHED CHARACTERIZATION 2.1 Drainage Area The project has a contributing drainage area of 33.33 square miles (21,331 acres) at the downstream limits of the site and contains the headwaters of New Hope Creek. Figure 2 shows the location of site within the project watershed. 2.2 Surface Water Classification / Water Quality The project site is located within the North Carolina Division of Water Quality (DWQ) Subbasin 03-06- 05. This reach of New Hope Creek (16-41-1-(0.5)) is classified for Class C uses, which are protected for secondary recreation, fishing, wildlife, fish and aquatic life propagation and survival, agriculture, and other uses suitable for Class C. Secondary recreation includes wading, boating, and other uses involving human body contact with water where such activities take place in an infrequent, unorganized, or incidental manner. There are no restrictions on watershed development or types of discharges. Additionally, the stream is designated as a Nutrient Sensitive Water (NSW), a supplemental classification intended for waters that require additional nutrient management, because of the susceptibility to excessive growth of microscopic or macroscopic vegetation (NCDENR, DWQ 2005). 2.3 Physiography, Geology and Soils The project watershed is located within the Piedmont physiographic province and is part of the Triassic Basins Level 1V Ecoregion. The Triassic Basin has many easily widening stream valleys and less local relief than in surrounding regions. Sedimentary rocks of the Chatham Group underlie the site. The geology is described as arkosic sandstone, which is tan, medium to very coarse-grained, and micaceous (NCDENR Geologic Survey 2005). Project Site, Orange & Durham Counties, NC Erwin Rd Mt.

The Chewacla soils consist of very deep, moderately permeable, somewhat poorly drained soils on floodplains along bottomlands, creeks and rivers. They develop from recent alluvium washed from soils formed in residuum from schist, gneiss, granite, phyllite, and other metamorphic and igneous rocks. They occur on nearly level floodplains along streams that drain from the mountains and the Piedmont. Wehadkee soils are also shown as existing on the site and this soil type consist of very deep and very poorly drained soils on nearly level floodplains along streams that drain from the mountains and the Piedmont. The Wehadkee soils typically occur with Chewacla soils. They are more poorly drained than the Chewacla soils and they are darker in color and more intensely mottled. A map of the soils within the project watershed is seen in Figure 3. The county soil survey classifications, however, were not fully consistent with the soil conditions observed on-site by a KCI soil scientist (see Section 3.3.2). 2.4 Historical Land Use and Development Trends The project watershed is located almost exclusively (97.3%) in Orange County. Approximately 83% of the watershed is forested based on the North Carolina GAP land use classification, which used 1992 and 1993 aerial photography (McKerrow 2003). Table 1 describes the various land uses in the project watershed. Table 1. Existing Land Use in Project Watershed Land Use Acreage Percentage Forest 17,718.6 83.1% Agricultural 2,000.4 9.4% Rangeland 727.9 3.4% Urban or built-upland 493.9 2.3% Wetland 264.2 1.2% Water 122.5 0.6% Barren land 2.9 0.0% Total 21,330.6 100%11 The project watershed and surrounding area continue to experience rapid growth. Downstream and outside of the project watershed there is residential and commercial development expanding along the North Carolina State Highway 15-501 corridor to the east. However, a large area of the project watershed is within Duke Forest, a 7,200-acre research forest owned by Duke University. There has also been an effort among local governments and citizens to protect land along New Hope Creek and create a protected corridor all the way to Jordan Lake. Historic aerial photographs dating from 1955 show the site under cultivation or in pasture in the last fifty years (Appendix 1). Drainage ditches throughout the site are evident in each of the photographs. The landowner reports that several ditches along the property were constructed in the 19`" century. A large floodplain pool feature in the southeast corner of the project site is visible in all of the historic images. 2.5 Endangered / Threatened Species As part of the initial environmental documentation for this project, a Categorical Exclusion (CE) was completed.

The NCNHP found no records of protected or rare species within a mile of the project site (see Appendix 2). 2.6 Cultural Resources A visit to the North Carolina State Historic Preservation Office (SHPO) revealed no historic properties or archaeological resources within the project limits. KCI submitted a formal request for review of the site to SHPO. The office responded that they were not aware of any cultural resources that would be affected by the restoration project (see Appendix 2). 2.7 Potential Constraints As part of the CE documentation process, a limited Phase I site assessment was conducted to verify whether the site was listed in any state or federal environmental databases such as hazardous waste sites or underground storage tanks. The site was not identified in any databases and a summary of the limited Phase I report is included in the CE report. In addition, the project site was examined for any potential hindrances to a successful restoration project. The evaluation focused on hazardous materials, utilities, restrictive easements, and the potential for hydrologic trespass. Table 3 summarizes the identified constraints related to the implementation of site restoration activities. Table 3.

A search was completed to investigate any utilities present within the project site and none were found. 2.7.4 FEMA / Hydrologic Trepass The property is located within the 100-year floodplain of Upper New Hope Creek as determined by the . Federal Emergency Management Agency (FEMA). As shown in Figure 4, the entire project site boundary is located in Zone AE. There will be no hydrologic trespass on any bordering properties. 3.0 PROJECT SITE WETLANDS i The project site exists on the floodplain of New Hope Creek. The land has long been used for agriculture and has been drained with an extensive ditch network. The existing site conditions are shown in the project photographs (Appendix 3). 3.1 Jurisdictional Wetlands Existing wetlands were delineated in August 2005 using the methods described by the US Army Corps of S Engineers (USACE 1987). The delineation forms used for the project site are available in Appendix 4. . The wetland boundaries are shown in Figure 5 and were approved by the USACE as the existing jurisdictional wetlands (Appendix 5). . 3.2 Hydrological Characterization The site hydrology has been greatly affected by a series of ditches that all drain to New Hope Creek. The . existing hydrologic conditions are shown in Figure 6. Project Streams and Ditches There are no streams that flow directly through the project site. Upper New Hope Creek forms the . eastern boundary of the project and the entire site eventually drains to this stream. There is a series of major and minor drainage ditches that run along and throughout the site. Ditches #1 and #2 are two large ditches that are each approximately one foot deep and they carry water from a small subwatershed that drains directly to the site. Ditch #3 drains water through the center of the site and diverges into Ditches #4 and #5 before all of this drainage exits via Ditch #6. Running along the southern boundary of the project boundary, Ditch #6 provides the major outlet for the site. Ditch #7 currently allows excess water to drain from the eastern portion of the site. Ditch #9 runs along the northern site boundary and drains a . small subwatershed to New Hope Creek. When water levels in New Hope Creek rise high enough to cause backwater into Ditch #9, this flow travels into Ditch #8, which during large flood events appears to flow in either direction as water levels fluctuate, although it is bordered by a 2-foot berm on the southern . bank. When Ditch #9 experiences enough flow to exceed its banks, the excess is carried through the site by Ditch #3. However, another 2 to 3-foot berm has been constructed from the spoil remains of Ditch #9 that prevents this ditch from flooding except during extreme events. Ditches #10 and #11 arc small sloughs from Ditch #9 and frequently remain ponded. During larger flooding events, backwater from 7 iIM milt_ Figure 5.

I? New Hope Creek travels down Ditch #12. Ditch #13 carries drainage down from the eastern side of the property. Smaller minor ditches are distributed throughout the site at approximately 50 feet apart, which contribute to a significant loss of water from the site as well. Project Wetlands The site is located on an expansive and active floodplain of New Hope Creek. Moving west from the stream, the site slopes downward at approximately 1% from the levee position of the creek to a lower floodplain position in the center of the site. This central portion is flat extending to the north, south and west to the valley walls on the site. Existing Piedmont Bottomland Hardwood wetlands are found in some of the forested areas of the project site. In the northern part of the site, drainage from the north forms a wetland in a depressional area that ponds consistently. The drainage from this wetland leads to another small wetland approximately 200 feet south in a small stand of hardwood trees. Another wetland exists toward the southern end of the site and Ditch #5 currently runs through this section. A Floodplain Pool community is found in the southeastern portion of the project site. This wetland experiences flooding for a large part of the year. Several minor ditches from the eastern half of the property flow into this wetland and excess drainage is able to exit via Ditch #7. All of the existing wetlands on the site receive occasional inputs from New Hope Creek flood events. However, ditches carry water away from all of the wetlands and reduce the amount of total hydrologic input that remains on-site. Confirmation of Riverine Condition (5-year,Jloodplain) FEMA originally used a HEC-2 model to determine flood elevations for New Hope Creek. KCI obtained this existing flood model and imported it into HEC-RAS. Once the model was calibrated to match the - results calculated with HEC-2, it was used to analyze the flood frequency at the Brown Site. In its previous analysis, FEMA provided flood elevations for 10, 50, 100, and 200-year flood events. In order to develop elevations for more frequent flooding events, a Log Pearson III flood frequency analysis was used to estimate discharges for 1, 2 and 5-year events. Because there is no stream gauge available at the project site, we used peak annual streamflow data from 1983 to 2004 from the nearest United States Geologic Survey (USGS) stream gauge on New Hope Creek, Station 02097314 (approximately six miles southeast of the Brown Farm). A log-log linear equation was then created with an R2 of 0.99 to relate the discharge at the gauge to the discharge values known for New Hope Creek. This relationship was used to estimate discharges for more frequent flood events at the project site. Based on results from this method, the elevation for a 5-year flood event was 256.3 feet at the upstream portion of the site and 255.38 feet at the downstream end of the site. Using these figures, the entire site would be inundated excluding only the spoil piles that reach 258 feet along Ditches #8 and #9. An analysis was also completed to look at how often a flood event would reach the site. Using the same procedure as above, flood waters are predicted to move onto the site during a 1.1-year flooding event. At this point, the model indicates that water will enter the site from below at an elevation of approximately 253 feet. During a 1.2-year event, the site is predicted to flood from both the northern and southern edges. With an event of this magnitude, the floodwaters are projected to enter the site from the north at an elevation estimated at 254.5 feet. Based on this analysis, flooding events are a significant hydrologic input to the project site. I• • • • 3.2.1 Groundwater Gauges High groundwater has been reported historically for the site and occurs seasonally at or near the surface in the surrounding natural areas. The project site has a high water table, because of its level location along a large floodplain. The groundwater within the project site is being evaluated by monitoring the water level with three on-site HOBO recording pressure gauges. Three gauges were installed at the site in early 2006 and the locations are shown in Figure 6. The gauges were programmed to measure water levels twice daily at 12-hour intervals. 3.2.2 Hydrologic Budget for Restoration Site Existing Conditions Existing site hydrology was modeled by developing an annual water budget that calculates water inputs and outputs in order to calculate the change in storage on a monthly time step (Appendix 6). In order to set up the water budget, historic precipitation data were obtained from the North Carolina State Climatic Office. The nearest weather station to the Brown Site is Station 312515 in Durham, North Carolina. This station is located approximately 5.5 miles northeast of the project site. Monthly precipitation totals from the entire period of record (1899-2005) were reviewed and three years were selected to represent a range of precipitation conditions: dry year (1941), average year (1956), and wet year (1975). Potential inputs to the water budget include precipitation, groundwater, and surface inputs. For precipitation, the data from the three selected years were used in the budget. Groundwater input likely exists, but was considered negligible in comparison to the magnitude of surface and precipitation inputs. Surface water input was calculated using the USDA Soil Conservation Service (SCS) runoff curve number equation (1986). The results for this equation were computed using the US Army Corps of Engineers Hydrologic Engineering Center Hydrologic Modeling System (HEC-HMS). Outputs from the site include potential evapotranspiration (PET), groundwater, and surface water outlets. PET was calculated by the Thornthwaite method using mean monthly temperatures determined from the chosen years of record: 1941, 1956, and 1975. Groundwater represents losses from the site due to downward seepage through the soil profile and was assumed to be 2x10-6 ft/min (1.04 inches per month), which is typical of low permeability soils associated with wetlands. A substantial amount of water is also lost through the existing ditches on-site. A DRAINMOD model was set up to simulate the effect of the existing drainage network on wetland hydrology. The program evaluated 40 years of available precipitation data and produced the annual loss due to the ditches. The annual loss was then averaged on a monthly basis for dry, average, and wet years. Once the inputs and outputs were determined, a net monthly total was calculated in inches and used to estimate a yearly water budget. The model assumes unsaturated conditions at the beginning of the year. A maximum wetland water volume of 5.4 inches was calculated based on the specific yield of 0.15 for 36 inches of Wehadkee soil in order to analyze conditions in the upper three feet of the soil profile. The resulting hydrographs for the average, dry, and wet years show a seasonal pattern. The model shows that the majority of hydrologic inputs to the site come during the rainy spring months. The site begins to lose saturation in the upper twelve inches in the summer months. The late fall sees an increase in hydrologic inputs again. The dry year shows very little hydrology overall. The water budget does predict that wetland hydrology would exist in the average and wet years. However, this trend does correspond to conditions observed on-site and indicates that the model is not entirely representative of the true site conditions. Groundwater gauges on the site since early 2006 show large fluctuations in the data with the site at times experiencing hydrology below or at jurisdictional levels. The US Army Corps of Engineers 12 0 performed a wetland determination at the site on February 1, 2006 and verified that apart from in the 3.32 acres of existing wetlands the site does not have adequate jurisdictional hydrology (see Appendix 5). • Proposed Conditions A second water budget was developed to analyze the effect of restoration actions on the site hydrology. The loss of water from the existing ditches was removed from the budget, because these ditches will be Ali filled. To estimate the impact from recreating wetland microtopography, an additional two inches of • hydrologic capacity was added to the calculations. Based on these changes, the budget shows a noticeable increase in the spring. In particular, the wet year has wetland hydrology throughout almost the entire year. The dry year does not show much change from the existing to proposed budget, which a indicates that during a drought year the wetland may not experience much saturation. a One factor not taken into account in the annual water budget calculations is the effect of flooding. The a flood analysis described in Section 3.2 predicts that the site will experience frequent flooding events. Based on the existing conditions, these floodwaters would not be retained on-site and would instead drain out through the series of ditches. Under proposed conditions, the input from these flooding events would be able to remain on-site, because of the small depressions and rises associated with recreated wetland • microtopography. 3.3 Soil Characterization A soils investigation was conducted by a certified soil scientist from KCI to determine the extent and distribution of the hydric soils on the site and to classify the predominate soils to the soil series level. The investigation consisted of delineating the hydric soil boundaries with pink flagging in accordance with the US Army Corps of Engineers (1987). Areas that were identified as possible hydric soil mapping units • were surveyed at a higher intensity until the edge of the mapping unit was identified. The boundary of the hydric and non-hydric soil mapping units were then followed by continual sampling and observations as the boundary line was identified and delineated. In those areas where the boundary was found to be a - broad gradient rather than a distinct break, microtopography, landscape position, soil textural changes, redoximorphic features, and depleted matrices were additionally considered to identify the extent of the hydric soils. To develop a detailed soils map, several soil borings were advanced on the site in the general hydric soil areas identified by landscape position, vegetation and slope. Once the hydric soil borings were identified, the soil scientist marked the point and established a visual line to the next auger boring where again hydric soil conditions were confirmed by additional borings. The soil scientist moved along the edges of the mapping unit and marked each point along the line. To confirm the hydric soil mapping unit, soil borings were advanced to a depth of 50 inches. The soil profile descriptions identified the individual horizons in the topsoil and upper subsoil as well as the depth, color, texture, structure, boundary, and evidence of restrictive horizons and redoximorphic features. The extent of the mapped hydric soils is shown in Figure 5. The project site has been in agricultural production for approximately 100 years, but no Prior Converted (PC) wetland determination has been made on the site by the USDA Natural Resources Conservation Service (NRCS). - 3.3.1 Taxonomic Classification The project soils were classified as Wchadkee (fine-loamy, mixed, active, nonacid, thermic Fluvaquentic Endoaqucpts) with inclusions of Chewacla (fine-loamy, mixed, active, thermic Fluvaquentic Dystrudepts). I!? 13 3.3.2 Profile Description The Orange and Durham County Soil Surveys classify all the soils underlying the site as Chewacla. However, this classification was inconsistent with the observed soil conditions at the site. A detailed soils investigation by a KCI soil scientist identified Wehadkee soils as occupying the central portion of the site where restoration will take place. This detailed soils investigation was conducted by angering numerous soil borings across the site in areas identified by landscape position, vegetation, and slope followed by the preparation of a soil map that identified the extent of each soil mapping unit. The resulting distribution of soils on-site is estimated to be 75% Wehadkee and 25% Chewacla. The Wehadkee and Chewacla soils are defined as hydric soils due to saturation for a significant period during the growing season and they are listed on the federal, state and county hydric soils lists (USDA, SCS 1976 and USDA, SCS 1977). The soils in the north-central portion of the project site do not have hydric features until a depth of approximately 18-24 inches. This is likely caused from overwash sediment from flooding events that have accumulated on top of the Wehadkee soil below. A detailed description of all of the soil profiles by a KCI soil scientist is provided in Appendix 7. The Chewacla soils consist of very deep, moderately permeable, somewhat poorly drained soils on floodplains along bottoms, creeks, and rivers. The soil is produced from recent alluvium washed from soils formed in residuum from schist, gneiss, granite, phyllite, and other metamorphic and igneous rocks. They occur on nearly level floodplains along streams that drain from the mountains and the Piedmont. The Wehadkee soils are very deep and very poorly drained and are found on nearly level floodplains along streams that drain from the mountains and the Piedmont. The Wehadkee soils commonly occur with Chewacla soils. They are more poorly drained, darker in color, and more intensely mottled than the Chewacla soils (USDA, SCS 1976 and USDA, SCS 1977). 3.3.3 Soil Properties The physical properties for Wehadkee and Chewacla are identified in Table 4.

The percent organic matter for Chewacla differs slightly at 6-36 inches in the descriptions in the Soil Survey of Orange County (USDA, SCS 1977). 3.4 Plant Community Characterization At the site there are three existing vegetation types: agriculture, Piedmont Bottomland Hardwood Forest, and Floodplain Pool. Agriculture - 32.0 acres The agricultural area consists of land cut for hay and occasionally used for pasture. The site has been under continuous production for the past 100 years. A series of ditches exist throughout the agricultural field. Two large ditches direct water around and/or through the site while many smaller ditches channel flow to the larger drainage network. There are several trees growing in places among the agricultural fields. There is a line of trees running from north to south and within this grouping of trees there are 14 several mature willow oak (Quercus phellos) and sugarbery (Celtis laevigata) along with a row of eastern redcedar (Juniperus virginiana). Piedmont Bottomland Hardwood Forest - 1.2 acres On the northern edge of the project site, there is an established Piedmont Bottomland Hardwood Forest community. There are also two other small wetlands of this community type in the center of the site as well as along the southern edge. These wetlands experience seasonal inundation and have had standing water during recent site visits. There is a diverse mixture of hardwood species, which include red maple (Aces rubrum), sugarberry (Celtis laevigata), sweetgum (Liquidambar stvracua), green ash (Fraxinus pennsylvanica), river birch (Betula nigra), deciduous holly (Ilex decidua), and American elm (Ulmus americana). Floodplain Pool- 2.1 acres This community exists along the southern border of the project site and sits in a depression that is lower than the rest of the project site. The wetland is saturated much of the year and contains mature vegetation such as green ash (Fraxinus pennsylvanica), river birch (Betula nigra), red maple (Acer rubrum), and American elm (Ulmus americana). Nonnative Plant Species The site has also been invaded by several non-native plant species. Populations of Chinese privet (Ligustrum sinese), Japanese honeysuckle (Lonicera japonica), and multiflora rose (Rosa multiflora) inhabit portions of the site. 4.0 REFERENCE WETLANDS The reference wetland is located approximately 0.8 miles from the Brown Site. It is also within the floodplain of New Hope Creek and is downstream from the project site. The property is owned by the County of Durham and is included in a larger area of land protected as the New Hope Creek Bottomlands. The site location is shown in Figure 7 and photographs of the reference site are seen in Appendix 8. KCI performed a wetland determination at the reference site. The USACE data sheets used for this procedure are in Appendix 9. 4.1 Hydrological Characterization The site is located in the New Hope Creek Watershed as and the reference wetland watershed is seen in Figure 8. Similar to the project site, the reference wetland receives hydrologic inputs from a high groundwater table and seasonal flooding from New Hope Creek. Within the reference wetland, there are many physical markers of wetland hydrology. There are buttressed trunks, sediment marks on trees, and drainage patterns. 4.1.1 Gauge Data Summary The groundwater within the reference wetland will be evaluated by monitoring the water level with an on- site HOBO recording pressure gauge. Data from this gauge will be compared to gauges at the restoration areas. The gauge will be programmed to measure water levels twice daily at 12-hour intervals. The data will be downloaded periodically and evaluated to determine the depth and duration of the groundwater level on the reference site. The reference wetland gage was installed in early 2006 and its location is shown in Figure 9. 4.2 Soil Characterization The soil type as described in the Soil Survey of Durham County is shown in Figure 10 (USDA, SCS 1976). According to the soil survey, the soil type is Chewacla and Wehadkee series. This is consistent 15 Figure 8.

The extent of the community type and the surrounding land uses are shown in Figure H. 4.3.1 Community Description The trees within the reference wetland include a variety of hardwood species such as red maple (Acer rubrum), green ash (Fraxinus pennsylvanica), sweetgum (Liquidambar styraciflua), river birch (Betula nigra), sycamore (Platanus occidentalis), American elm (Ulmus Americana), slippery elm (Ulmus rubra), American hornbeam (Carpinus caroliniana), and painted buckeye (Aesculus sylvatica). 5.0 PROJECT SITE RESTORATION PLAN 5.1 Restoration Project Goals and Objectives This project proposes to improve water quality and expand wetland habitat by restoring agricultural land to a functioning riverine wetland ecosystem. Currently, the site is used for harvesting hay and occasional grazing, but it is located directly within the floodplain of New Hope Creek. This important water body contains unique aquatic habitat both upstream and downstream of the project site. New Hope Creek is listed as an impaired water body under the draft 2004 303(d) list for North Carolina starting approximately 2.4 miles downstream of the project site at the confluence with Sandy Creek. This segment of stream has impaired biological integrity from urban runoff and storm sewers (NCDENR, DWQ 2005a). Restoring this wetland will allow the site to retain a greater amount of floodwaters from New Hope Creek. Recent development in the New Hope Creek Watershed has increased the storm surge associated with precipitation events. Flood attenuation will increase by removing ditches that drain the site. The restored wetland will also provide water quality benefits by acting as a buffer to New Hope Creek from upstream agricultural and residential uses. These restoration activities will reduce both point and non- point source pollutants to the system and improve aquatic and terrestrial habitat. An overview of the mitigation type and extent at the project site is given in Figure 12. Current pastureland with drained hydric soils will be restored to wetland. Existing wetlands will be enhanced by improving the hydrology and vegetation. Surrounding upland areas on the site will be preserved to recreate a functioning ecosystem. The acreage in Table 5 below provides an overview of the restoration and enhancement wetland areas. Table 5.

W Functions that will be restored as a result of the mitigation include: ¦ Aquatic/Terrestrial Wildlife Habitat ¦ Water Quality ¦ Groundwater Recharge ¦ Nutrient Cycling ¦ Bottomland Hardwood Communities . 5. 1.1 Designed Wetland Type . The restored wetlands will be designed as a riverine wetland system. The area to be restored is within the active 5-year floodplain of the New Hope Creek and will receive inputs from numerous flood events. . Restoration will focus on filling existing ditches, removing fill and overburden, and creating wetland . microtopography to retain floodwaters and restore wetland hydrology. Wetland-specific hardwood species will be planted to establish hydrophytic vegetation. 5.1.2 Target Wetland Communities The main target community for the restoration area is a Piedmont Bottomland Hardwood Forest as described by Schafale and Weakley (1990). This wetland type has a canopy dominated by tree species such as tulip poplar (Liriodendron tulipfera), sweetgum (Liquidambar styraciflua), cherrybark oak (Quercus pagoda (falcata var. pagodaefolia)), swamp chestnut oak (Q. michauxii), American elm (Ulmus Americana), sugarberry (Celtis laevigata), green ash (Fraxinus penns_ylvanica), loblolly pine (Pinus taeda), shagback hickory (Carya ovata), and bitternut hickory (Carya cordiformis). Typical understory trees include American hornbeam (Carpinus caroliniana), red maple (Ater rubrum), flowering dogwood (Cornus.florida), American holly (Ilex opaca), and common pawpaw (Asimina triloba). Common shrubs are often species such as painted buckeye (Aesculus sylvatica) and American strawberry-bush (Evonymus americana). Invasive species such as Virginia dayflower (Commelina virginica), Japanese honeysuckle (Lonicera japonica), Japanese grass (Microstegium vimineum), and Asian spiderwort (Murdannia keisak) have the potential to invade this community type. . The typical Piedmont Bottomland Hardwood community is flooded at least occasionally. Bottomland Forests are believed to form a stable climax forest with uneven-aged canopy with primarily gap phase regeneration (Schafale and Weakley 1990). • In the existing wetlands, there is also a large Floodplain Pool community that will be enhanced. Schafale and Weakley describe this habitat as being found in depressions in abandoned river channels on floodplains in the mountains and the Piedmont. They typically hold standing water much or all of the year. In the center of these pools, there may not be any higher plants and aquatic plant species may dominate instead. The edges feature aquatic and wetland vegetation with species such as royal fern (Osmunda regalis var. spectabilis), handsome sedge (Carex,folliculata), fringed sedge (C. crinita), white edge sedge (C. debilis), broadwing sedge (C. alata), false nettle (Boehmeria cylindrical), water-pepper (Polygonum cespitosum), marsh seedbox (Ludwigia palustris), and Sphagnum spp. Shrubs such as hazel alder (Ahaus serrulata) may occur on the edge (Schafale and Weakley 1990). . 5.2 HEC-RAS Analysis The Brown Site is located entirely within the 100-year floodplain of New Hope Creek (Zone AE). FEMA originally used a HEC-2 model to analyze the flooding dynamics along New Hope Creek. KCI obtained . this HEC-2 model, brought the data into HEC-RAS, and calibrated the converted model to match the results produced by the original HEC-2 output. 5.2.1 No-rise, LOMR, or CLOMR With this HEC-RAS model, we modified the two cross-sections that go through the project site to reflect the changes in elevation from filling the ditches. Based on this analysis, KCI does not predict a rise in 23 ¦ base flood elevations. The modified HEC-RAS model showed a rise less than or equal to 0.01 feet. A No-Rise Certification letter explains these results in Appendix 10. 5.2.2 Hydrologic Trepass There will be no hydrologic trespass to any landowners upstream or downstream of the Brown Site. The planned actions will not encroach on any neighboring land and any increased flooding is anticipated to stay within the project limits based on the flood analysis described in previous sections above. 5.3 Hydrological Modifications Hydrologic modifications will focus on restoring surface water retention to this wetland system. Currently, existing ditches and berms force water out of the system and prevent surface water from remaining on-site and recharging the groundwater. Hydrologic restoration and enhancement will focus on filling in these ditches that were constructed to drain the historic wetlands for agriculture. The restoration will also involve removing or breaching berms that currently force water into the ditches. Together these actions will allow surface and floodwaters to have greater access to the wetlands. Three level spreaders will also be constructed across the project site to allow hydrologic access across the entire area as would occur in a natural wetland. The modifications that will take place are displayed in Figure 13. 5.3.1 Narrative of Modifications Hydrologic modifications will focus on restoring historic wetland hydrology by removing ditches and berms that restrict flow from reaching and remaining on-site. Three level spreaders will be constructed to reconnect the hydrology across the entire site. Wetland restoration and enhancement are planned for the project site and described below. Riverine Wetland Restoration - 24.58 Acres Wetland restoration will take place on 24.58 acres of Wehadkee soils currently used for hay production and grazing. The hydrologic restoration will focus on removing ditches and berms. Ditches #1, #2, #3, #4, #7, #8, #12, and #13 will be filled. Berms that run along the southern edges of Ditches #8 and #9 will be removed where feasible; mature trees exist in places along the berm and will be left in place. In order to block the remaining flow from minor ditches that run primarily north to south, microtopography will be oriented perpendicular (i.e. southwest to northeast). This grading method will effectively create small depressions and rises across the landscape while stopping the flowpath from these ditches. Using this procedure will also allow some of the existing grasses to remain in place and stabilize the system in the case that a extreme flooding event from New Hope Creek were to occur shortly after construction. Fences are already in place to restrict cattle access to the restored wetland. In some locations, up to six inches of fill/overburden will be removed from the top surface of the soil. This layer to be removed is a combination of overwash sediments that have accumulated from flooding events and spoil remains from the extensive series of ditches that were constructed on the site. Three level spreaders will be installed throughout the project site as displayed in Figure 13. These features will spread across the site in several places and are designed to mimic the elongated flowpath in a natural wetland. One will begin at a point just upstream of where Ditch #9 drains into New Hope Creek and wrap around to the central portion of the site. Another level spreader will take the flow that is coming from Ditch #1 and pull this across the site to the east. A final level spreader will be installed from the north-central portion of the site and allow water to seep toward southeast. Riverine Wetland Enhancement - 3.32 Acres Currently the existing wetlands on-site have adequate wetland hydrology and most have an intact hardwood canopy. However, these wetlands have been modified by ditches throughout the site that drain a significant amount of water. The hydrology to these wetlands will be enhanced by filling Ditches #3, 24 Figure 13.

The only remaining outlet that will allow water to leave the site will be through a stabilized ditch plug outlet where Ditches #4 and #5 enter Ditch #6. 5.3.2 Scaled Schematic of Modifications A diagram of the proposed restoration and enhancement actions is shown in Figure 13. It describes the activities that will restore the site. 5.4 Natural Plant Community Restoration Restoring natural vegetation will focus on establishing native wetland hardwood species in the entire wetland. The majority of the area will receive species consistent with a Piedmont Bottomland Hardwood Forest community. Enhancement areas will be planted with targeted hardwood species to increase species diversity. Populations of invasive species have also been identified and will be eliminated as much as possible. Restoration Plant Community The restoration wetland will be planted as a Piedmont Bottomland Hardwood Forest Community using the species described below, Approximately 436 trees per acre (10' x 10' spacing) will be planted to achieve a mature survivability of three hundred twenty (320) trees per acre. The site will be planted with 1-gallon container stock instead of bare root trees to improve the overall rate of survivability. Plant placement and groupings will be randomized during the restoration in order to create a more natural appearance. Woody vegetation planting will take place during dormancy. Tree species to be planted may consist of the following: Green ash Fraxinus pennsylvanica FACW Tulip poplar Liriodendron tulipfera FAC Water tupelo Nyssa aquatica OBL Laurel oak Quercus laurifolia FACW Overcup oak Quercus lyrata OBL Swamp Chestnut oak Quercus michauxii FACW- Cherrybark oak Quercus pagoda FACW Willow oak Quercus phellos FACW- The restoration area will be divided into two planting zones in order to target species to site conditions. These zones are shown in Figure 14. Zone A will be planted with tree species with obligate or facultative-wet designation and could include green ash (Fraxinus pennsylvanica), water tupelo (Nyssa aquatica), overcup oak (Quercus lyrata), swamp chestnut oak (Q. michauxii), and willow oak (Q. phellos). Zone B will be planted with facultative species such as green ash (Fraxinus pennsylvanica), tulip poplar (Liriodendron tulipfera), cherrybark oak (Quercus pagoda), and laurel oak (Q. laurifolia). Wetland Enhancement Enhancement plantings will consist of hardwood species with a obligate or facultative-wet designation, because these existing wetlands already experience a frequent level of saturation. The species will likely consist of the following: Water tupelo Nyssa aquatica OBL Laurel oak Quercus laurifolia FACW Overcup oak Quercus lyrata OBL 26 NL� Figure 14.

The Floodplain Pool Community will be planted at the same density, but the trees will be placed only in the outer fringes of the site where ponding is less frequent. Invasive Species Management The Brown Site has been affected by several nonnative plant species. One of the most significant invaders is Chinese privet (Ligustrum sinense); large thickets of the plant occupy the edges of the proposed restoration site. Japanese honeysuckle (Lonicera japonica) and multiflora rose (Rosa multiflora) have also spread into parts of the site. These species will be marked and treated with a glyphosate herbicide. Japanese grass (Microstegium vimineum) is also a pervasive nonnative plant in this area. As much native grass cover will be retained during the construction process as possible to minimize the amount of bare soil available to invasive plants. 6.0 PERFORMANCE CRITERIA A monitoring program will be implemented to observe the progress toward achieving mitigation goals and objectives within the restored wetland areas. The site will be deemed successful once wetland hydrology is established and vegetation success criteria are met. 6.1 Hydrology Groundwater elevations will be monitored to evaluate the attainment of jurisdictional wetland hydrology The reference wetland will also be monitored using the same procedures for comparative analysis. Monitoring Procedure Verification of wetland hydrology will be determined by automatic recording well data collected within the project area and reference wetland. Automatic recording gauges will be established within restoration areas at a density of one automatic well per four acres. Daily data will be collected from the automatic gauges over the 5-year monitoring period following wetland construction. Restoration Success Criteria Wetland hydrology will be considered established if well data from the site indicate that the water table is within 12 inches of the soil surface for 5% of the growing season during normal weather conditions. The growing season was taken from NRCS climatic data for Durham County, which has the closest meteorological station to the project site (Station NC312515). According to the NRCS, the growing season is considered to be the period with a 50% probability that the daily minimum temperature is higher than 28° F. The growing season for Durham County extends from March 24 to November 1 for a total of 222 days (USDA, NRCS 2003). Based on this growing season, success will be achieved at the project site if the water table is within 12 inches of the soil surface for 1 1 days or more during the growing season. 6.2 Vegetation The success criteria for the planted species in the restoration areas will be based on survival and growth. Beginning at the end of the first growing season, KCI will monitor vegetation for five years following the planting. Monitoring Procedure Permanent monitoring plots (10 by 10 meters) will be established in the wetland restoration areas at a density that will ensure 2% coverage of the total restoration acreage. Plots will be systematically located 28 to ensure even placement. Data will be collected at each plot for: total number of stems, species, percent survival, height, estimated percent cover of all species, and evidence of insects, disease or browsing. Restoration Success Criteria Survival of planted species must be 320 stems/acre at the end of five years of monitoring. Non-target species must not constitute more than 20% of the woody vegetation based on permanent monitoring plots. 6.3 Schedule / Reporting Monitoring data will be collected annually for a period of five years or until success criteria are achieved. Annual reports will be submitted to NCEEP and will document the monitored components of the restoration plan (hydrology and vegetation) and include all collected data, analyses, and photographs. Restoration of wetlands involves interpretation of collected information to devise a strategy that will ultimately lead to a functional ecosystem. Minor variations in the results can be anticipated due to unknown site conditions, inputs from outside the restoration site, regional climatic variations, or acts of God, etc. Correspondingly, nurturing the site with regular management activities is considered necessary to ensure that the goals and objectives of the project are met. These activities will be conducted throughout the year and may include invasive species control or other management activities. If the monitoring identifies failures in the project site, a remedial action plan will be developed to investigate the causes of the failure and propose actions to rectify the problem. 29 7.0 REFERENCES Environmental Laboratory. 1987.

Soil Profile Description Detailed Soils Investigation and Mapping for the Brown Site For the past 100 years, the soils on the Brown site have been altered by a ditch/spoil drainage system to prepare the land for cultivation. The primary ditch/spoil system to the north borders the site and depending on the size of the storm, diverts floodwaters either back to New Hope Creek or onto the site. During larger storm events, floodwaters pass through the ditch/spoil system via diversions conveniently placed at regularly spaced intervals and then flow overland across the site through the secondary lateral surface water ditches, which in turn are connected to the primary outlet ditch/spoil system to the south. The secondary lateral ditches are spaced approximately every 50 ft and the spoil was spread between the ditches to shed water to the drainage system. The landscape alterations have created a complex hydric soil mosaic on the landscape between the ditches and appear to create conditions necessary for overwash to be deposited at various locations on-site during storm events. It is apparent that these historic events have reshaped the floodplain and the hydric soil-forming processes on the site, but have not altered the forested areas to the north or the south that arc still in-line with the natural flood water flow direction. The Orange/Durham County Soil Survey has classified the soils underlying the site as Chewacla loarn. Based on field results, KCI Associates of North Carolina, P.A. (KCI) has remapped and reclassified the soils as primarily Wehadkee (Fine-loamy, mixed, active nonacid, thermic Fluvaquentic Endoaquepts). In areas of frequent overwash, the soil is classified as a Wehadkee variant, because of the sediment deposition and/or fill from man-made alterations. Some pedons have recent layers of overwash up to 20 inches thick that are loamy and variable in color as indicated by the range of characteristics for the Ap and A horizons of the Wehadkee series. The Wehadkee variant classification is transitory between the Wehadkee soils and the wetter phase of the Chewacla series. The Wehadkee series is listed as a hydric soil due to saturation for a significant period during the growing season and is in accordance with the federal, state, and county hydric soils list. This reclassification is based on our findings obtained from a detailed soils investigation. This detailed soils investigation was conducted by augering numerous soil borings across the site and classifying the soils in accordance with Soil Taxonomy. To verify the soil mapping units, five soil pits 18 inches deep followed by auger borings were advanced on-site and detailed soil descriptions were prepared for the vertical soil profile (see the following figure, Soil Descriptions with Soil Pit Numbers). These five soil profile descriptions share similar characteristics that have influenced the reclassification. The soil profile descriptions were prepared to highlight the visible soil alterations due to overwash, man-made ditching system and the consequent spoil associated with the drainage that is identified in the surface horizons on the site. This ditching network is also observed in the 2002 aerial photograph. The soils have primarily been buried by 10 to 17 inches of loamy textured materials that are variable in color, but occur within the • range of characteristics of the Ap and A horizons. Furthermore, a more detailed analysis of the stratification of the overwash was conducted to show the redoximorphic features that developed due to the horizontal stratification. The Bw horizon is variable in color and the C horizon is a massive compacted horizon that occurs above the buried solum. The 10 to 17 inches of soil material is a result of overbank flooding and excavated spoil materials spread on the site. The profile descriptions of the 10-17 inch horizons indicate the development of the following due to a fluctuating water table: soil color (Bw), iron concretions greater than 3mm within the upper 3 inches, and redoximorphic features. The site is, - however, sufficiently drained to prevent low chroma colors from forming. The asterisk that appears on the following soil descriptions indicates stable horizons that appear to have been developed naturally over time by natural soil-forming processes. The horizons above the asterisk appear to be overburden, which have multiple stratified horizons with little or no structure and differing colors and textures. Based on the information presented for the stable horizons designated with an asterisk, these soils show relic saturation and relic hydric soils below the overwash/spoil. Additionally, r during the winter and spring the soils have stored sufficient moisture to show a chroma 2 matrix across the site at 10 to 12 inches below the surface. However, during the summer and fall when the drainage system and evapotranspiration are at their peak these chroma 2 matrix colors become a chroma 2.5 or 3. Steven F.

The project limits include cross sections labeled 1928 through 1929 and in the HEC-RAS model; the project includes Section number 192819 to Section number 193912. The HEC-2 model was received from the floodplain manager for the City of Durham. A Duplicate Model was generated in HEC-RAS to perform this study. The Duplicate Model is the original HEC-2 model provided to KCI by the City of Durham. The HEC-2 model was imported into HEC-RAS and the published 100-year Base Elevations (BSE's) were duplicated by the model. Detailed field survey data was taken within the project area and will be reflected in the Conditional Model. The boundary conditions and discharge data in the models are based on the original model. Due to this data being available, a hydrological analysis was not performed. The HEC-RAS 3.1 computer program was used to perform the hydraulic analysis. A Conditional Model was generated in HEC-RAS by revising the existing cross sections at stations 192819 and station 193912. This Conditional Model serves as the baseline condition for the no-rise analysis for the proposed wetland restoration. The Proposed Model reflects the design of the wetland restoration. Three P-0" ditches will be filled-in and this change is reflected in the two cross sections through the project at station 192819 and station 193912. The results of the analysis indicate that the wetland restoration project will have no significant impact on the cross sections of the New Hope Creek Floodplain and as a result will not impact the base flood elevations (BSE's). This memo is to certify that the proposed Brown Farm Wetland Restoration Project will not impact the 100- year flood elevations, floodway elevations of floodway widths on the New Hope Creek, as shown on the preliminary FIRM map Panel No. 3720080000) at published sections in the Flood Insurance Study for Durham County dated May 05, 2005. ?-,26 -2006 ,, (Dated (Signature) KCI Associates of N.C.

Project Information Attach a vicinity map clearly showing the location of the property with respect to local landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property boundaries and development plans in relation to surrounding properties. Both the vicinity map and site plan must include a scale and north arrow. The specific footprints of all buildings, impervious surfaces, or other facilities must be included. If possible, the maps and plans should include the appropriate USGS Topographic Quad Map and NRCS Soil Survey with the property boundaries outlined. Plan drawings, or other maps may be included at the applicant's discretion, so long as the property is clearly defined. For administrative and distribution purposes, the USACE requires information to be submitted on sheets no larger than 11 by 17-inch format; however, DWQ may accept paperwork of any size. DWQ prefers full-size construction drawings rather than a sequential sheet version of the full-size plans. If full-size plans are reduced to a small scale such that the final version is illegible, the applicant will be informed that the project has been placed on hold until decipherable maps are provided. 1.

The River Basin map is available at http://h2o.enr.state.nc.us/admin/mgps/.) 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: The Brown Farm has been under cultivation or used for grazing for over 100 years. An extensive ditch network has allowed for agriculture despite the site's location on the New Hope Creek Floodplain. The area surrounding the project site Page 6 of 12 is experiencing rapid growth Downstream of the project site there is residential and commercial development expanding along the State Highway 15-501 corridor. Upstream, however, part of the project watershed is within Duke Forest, a 7,200-acre research forest owned by Duke University. 10. Describe the overall project in detail, including the type of equipment to be used: This wetland restoration project will reclaim the site as a riverine wetland. A bulldozer and/or front-end loader on tracks will be used to plug the selected channel and install a rock stabilized outlet. All work will be done on high ground when possible, but mats will be used as needed to protect jurisdictional wetlands. 11. Explain the purpose of the proposed work: The project will restore a 46.13-acre agricultural area to a Bottomland Hardwood wetland ecosystem. Existing ditches on-site do not represent natural site conditions and prevent or limit the formation of wetland hydrology. IV. Prior Project History If jurisdictional determinations and/or permits have been requested and/or obtained for this project (including all prior phases of the same subdivision) in the past, please explain. Include the USACE Action ID Number, DWQ Project Number, application date, and date permits and certifications were issued or withdrawn.

Pfeiffer, Project Manager jpfeifferAkci.com 919-783-9214 June 2006 Executive Summary The Brown Farm Wetland Restoration proposes to improve water quality and expand wetland habitat by restoring agricultural land to a functioning riverine wetland ecosystem. Currently, the site is used for harvesting hay and occasional grazing and is located directly within the floodplain of New Hope Creek in the Cape Fear Basin. This important water body contains unique aquatic habitat both upstream and downstream of the project site. The project will restore 24.58 acres of wetland and enhance 3.32 acres of existing wetlands along the New Hope Creek Corridor. The Brown Farm is adjacent to New Hope Creek in Durham, North Carolina along the Orange-Durham County Line. The site drains into New Hope Creek to the east, which then flows approximately 11 miles - before entering Jordan Lake. The project has a contributing drainage area of 33.33 square miles (21,331 acres) at the downstream limits of the site. New Hope Creek is listed as an impaired water body under the draft 2004 303(d) list for North Carolina starting approximately 2.4 miles downstream of the project site at the confluence with Sandy Creek. This segment of stream has impaired biological integrity from urban runoff and storm sewers. Historic aerial photographs dating from 1955 show the site under cultivation or in pasture in recent years. Currently, the project watershed is approximately 83% forested based on the North Carolina GAP land use classification, but the surrounding area continues to experience rapid growth. Downstream and outside of the project watershed, there is residential and commercial development expanding along the North Carolina State Highway 15-501 corridor to the east. The Orange and Durham County Soil Surveys classify the soils at the site as primarily Chewacla with some Wchadkee. Tile county soil survey classifications, however, were not fully consistent with the conditions observed on-site by a KCI soil scientist. A detailed soils investigation was conducted across the site and the resulting distribution of soils at the Brown Farm is estimated to be 75% Wehadkee and 25% Chewacla. The Wchadkee and Chewacla soils are defined as hydric soils due to saturation for a significant period during the growing season. The project site is located on an expansive, active floodplain of New Hope Creek. Moving west from the stream, the site slopes downward at approximately 1% from the levee position of the creek to a lower floodplain position in the center of the site. This central portion is flat extending to the north, south and west to the valley walls on the site. Existing wetlands were delineated in August 2005 using the methods described by the US Army Corps of Engineers. There arc 3.32 acres of jurisdictional wetlands on the property. There are no streams that flow directly through the project site. Upper New Hope Creek forms the eastern boundary of the project and the entire site eventually drains to this stream. There is a series of major and minor drainage ditches that run along and throughout the site. The landowner states that some of the larger ditches have been in place since the 19`' century. Smaller minor ditches are distributed throughout the site at approximately 50 feet apart. This extensive ditch network reduces the amount of total hydrologic input that can remain on-site. A reference wetland was found approximately 0.8 miles from the Brown Site and was used to guide the restoration design. It is also within the floodplain of New Hope Creek and is downstream from the project site. The property is owned by the County of Durham and is included in a larger area of land protected as the New Hope Creek Bottomlands. The composition of plant species at the reference wetland is best described as a Piedmont Bottomland Hardwood Forest. Using the reference wetland and existing site conditions, a restoration design was developed for the Brown Farm. Current pastureland with drained hydric soils will be restored to wetland. Existing wetlands will be enhanced by improving the hydrology and vegetation. Surrounding upland areas on the site will be included to recreate a functioning ecosystem. Hydrologic modifications will focus on restoring historic wetland hydrology by removing ditches and berms that restrict flow from remaining on-site. Three level spreaders will also be constructed to reconnect the hydrology across the entire site. These features will spread across the site in several places and are designed to mimic the natural, elongated flowpath in a wetland. In order to block the remaining flow from leaving via minor ditches that run primarily northwest to southeast, wetland microtopography will be oriented perpendicular (i.e. southwest to northeast). This grading method will effectively create small depressions and rises across the landscape while stopping the flowpath from these ditches. Using this procedure will also allow some of the existing grasses to remain in place to stabilize the system. The restoration of natural vegetation will focus on establishing native wetland hardwood species in the entire wetland. The majority of the area will receive species consistent with a Piedmont Bottomland Hardwood Forest community. Enhancement areas will be planted with targeted hardwood species to increase species diversity. One section of the enhancement area is a Floodplain Pool community and will be planted as such. Populations of invasive species have also been identified and will be eliminated as much as possible. A monitoring program will be implemented to observe the progress toward achieving mitigation goals and objectives within the restored wetland areas. The site will be deemed successful once wetland hydrology is established and vegetation success criteria are met. Management activities will be conducted as necessary to control invasive species or handle other issues as they arise. The restoration of the Brown Farm to a functioning wetland will allow the site to retain a greater amount of floodwaters from New Hope Creek. The wetland will also provide water quality benefits by acting as a buffer to New Hope Creek from upstream agricultural and residential uses. These restoration activities will reduce both point and non-point source pollutants to the system and improve aquatic and terrestrial habitat along the New Hope Creek Corridor. 11 BROWN FARM RESTORATION PLAN TABLE OF CONTENTS INTRODUCTION .............................................................................................. 1.0 PROJECT SITE IDENTIFICATION AND LOCATION ..................... 1.1 Directions to Project Site ................................................................... 1.2 USGS Hydrologic Code and NCDWQ River Basin Designations.... 2.0 WATERSHED CHARACTERIZATION .............................................. 2.1 Drainage Area .................................................................................... 2.2 Surface Water Classification / Water Quality ................................... 2.3 Physiography, Geology and Soils ...................................................... 2.4 Historical Land Use and Development Trends .................................. 2.5 Endangered / Threatened Species ...................................................... 2.6 Cultural Resources ............................................................................. 2.7 Potential Constraints .......................................................................... 3.0 PROJECT SITE WETLANDS .............................................................. 3.1 Jurisdictional Wetlands ...................................................................... 3.2 Hydrological Characterization ........................................................... 3.3 Soil Characterization ......................................................................... 3.4 Plant Community Characterization ................................................... 4.0 REFERENCE WETLANDS .................................................................. 4.1 Hydrological Characterization ........................................................... 4.2 Soil Characterization ......................................................................... 4.3 Plant Community Characterization ................................................... 5.0 PROJECT SITE RESTORATION PLAN ............................................. 5.1 Restoration Project Goals and Objectives ......................................... 5.2 HEC-RAS Analysis ........................................................................... 5.3 Hydrological Modifications ............................................................... 5.4 Natural Plant Community Restoration .............................................. 6.0 PERFORMANCE CRITERIA ............................................................... 6.1 Hydrology .......................................................................................... 6.2 Vegetation .......................................................................................... 6.3 Schedule / Reporting ......................................................................... 7.0 REFERENCES ...................................................................................... .......... 1 .......... 1 .......... 1 .......... 1 ..........1 .......... 1 .......... 1 .......... 1 .......... 4 ..........4 .......... 6 .......... 6 .......... 7 .......... 7 .......... 7 ........13 ........14 ........ 15 ........15 ........15 ........ 20 ........ 20 ........ 20 ........ 23 ........ 24 ........ 26 ........ 28 ........ 28 ........ 28 ........ 29 ........ 30 iii FIGURES Figure 1.

INTRODUCTION This restoration plan outlines the existing conditions at the Brown Farm Wetland Restoration Site and the process that will be used to restore riverine wetlands along New Hope Creek in Durham and Orange - counties. Using results from field studies and a literature review, this document provides an overview of the planned restoration project. The hydrology, soils, and vegetative communities at a nearby reference wetland are included and will serve as a model to shape the final restoration design. Once completed, the project will add another piece to the protected areas along the New Hope Creek Corridor. 1.0 PROJECT SITE IDENTIFICATION AND LOCATION 1.1 Directions to Project Site The Brown Farm Site is located adjacent to New Hope Creek and is approximately two miles west of Durham, North Carolina along the Orange-Durliam County Line as seen in Figure 1. The site is approximately one mile east of the intersection of Erwin Road and Mt. Moriah Road and is located on United States Geologic Survey (USGS) Southwest Durham and Chapel Hill Quadrangles. The project site is approximately located at 35.9670 N Latitude and 78.9977 W Longitude (WGS 1984). . 1.2 USGS Hydrologic Code and NCDWQ River Basin Designations The property is in the 03030002 (Upper Cape Fear 02) Watershed Cataloging Unit (8-digit HUC) and the 03030002060110 (Upper New Hope Creek) Local Watershed Unit (14-digit HUC). The site drains into © New Hope Creek to the east, which then flows approximately 1 1 miles before entering Jordan Lake. In the North Carolina Ecosystem Enhancement Program's (EEP) Cape Fear River Basin Watershed Restoration Plan, the Upper New Hope Creek Watershed (030300020601 10) has been identified as a high priority Targeted Hydrologic Unit/Watershed. 2.0 WATERSHED CHARACTERIZATION 2.1 Drainage Area The project has a contributing drainage area of 33.33 square miles (21,331 acres) at the downstream limits of the site and contains the headwaters of New Hope Creek. Figure 2 shows the location of site within the project watershed. 2.2 Surface Water Classification / Water Quality The project site is located within the North Carolina Division of Water Quality (DWQ) Subbasin 03-06- 05. This reach of New Hope Creek (16-41-1-(0.5)) is classified for Class C uses, which are protected for secondary recreation, fishing, wildlife, fish and aquatic life propagation and survival, agriculture, and other uses suitable for Class C. Secondary recreation includes wading, boating, and other uses involving human body contact with water where such activities take place in an infrequent, unorganized, or incidental manner. There are no restrictions on watershed development or types of discharges. Additionally, the stream is designated as a Nutrient Sensitive Water (NSW), a supplemental classification intended for waters that require additional nutrient management, because of the susceptibility to excessive growth of microscopic or macroscopic vegetation (NCDENR, DWQ 2005). 2.3 Physiography, Geology and Soils The project watershed is located within the Piedmont physiographic province and is part of the Triassic Basins Level IV Ecoregion. The Triassic Basin has many easily widening stream valleys and less local relief than in surrounding regions. Sedimentary rocks of the Chatham Group underlie the site. The geology is described as arkosic sandstone, which is tan, medium to very coarse-grained, and micaceous (NCDENR Geologic Survey 2005). 70 \ ?( A, I l Project Site, Orange & Durham Counties, NC ORANGE D RHA e j COUNTY N -II \ r 1, -- -_? i ' Erwin Rd ? / I.?

The Orange and Durham County Soil Surveys classify the soils at the site as Chewacla. The Chewacla soils consist of very deep, moderately permeable, somewhat poorly drained soils on floodplains along bottomlands, creeks and rivers. They develop from recent alluvium washed from soils formed in residuum from schist, gneiss, granite, phyllite, and other metamorphic and igneous rocks. They occur on nearly level floodplains along streams that drain from the mountains and the Piedmont. Wehadkee soils are also shown as existing on the site and this soil type consist of very deep and very poorly drained soils on nearly level floodplains along streams that drain from the mountains and the Piedmont. The Wehadkee soils typically occur with Chewacla soils. They arc more poorly drained than the Chewacla soils and they are darker in color and more intensely mottled. A map of the soils within the project watershed is seen in Figure 3. The county soil survey classifications, however, were not fully consistent with the soil conditions observed on-site by a KCI soil scientist (sec Section 3.3.2). 2.4 Historical Land Use and Development Trends The project watershed is located almost exclusively (97.3%) in Orange County. Approximately 83% of the watershed is forested based on the North Carolina GAP land use classification, which used 1992 and 1993 aerial photography (McKerrow 2003). Table 1 describes the various land uses in the project watershed. Table 1. Existing Land Use in Project Watershed Land Use Acreage Percentage Forest 17,718.6 83.1% Agricultural 2,000.4 9.4% Rangeland 727.9 3.4% Urban or built-up land 493.9 2.3% Wetland 264.2 1.2% Water 122.5 0.6% Barren land 2.9 0.0% Total 21,330.6 100% The project watershed and surrounding area continue to experience rapid growth. Downstream and outside of the project watershed there is residential and commercial development expanding along the North Carolina State Highway 15-501 corridor to the cast. However, a large area of the project watershed is within Duke Forest, a 7,200-acre research forest owned by Duke University. There has also been an effort among local governments and citizens to protect land along New Hope Creek and create a protected corridor all the way to Jordan Lake. Historic aerial photographs dating from 1955 show the site under cultivation or in pasture in the last fifty years (Appendix 1). Drainage ditches throughout the site arc evident in each of the photographs. The landowner reports that several ditches along the property were constructed in the 19°i century. A large floodplain pool feature in the southeast corner of the project site is visible in all of the historic images. 2.5 Endangered / Threatened Species As part of the initial environmental documentation for this project, a Categorical Exclusion (CE) was completed. The CE included a review of any potential impacts on endangered or rare species from the proposed project. A summary of the information has been included below and more detailed information can be found in the CE. A review of the United States Fish and Wildlife Service's (USFWS) listing of federally endangered or threatened species under the Endangered Species Act revealed four species in Orange County and three 4 1 O Altavista Fine Sandy Loam, 0 To 3 Percent Slopes Aa Chewacla and Wehadkee Soils (Durham Co.)

The NCNHP found no records of protected or rare species within a mile of the project site (see Appendix 2). 2.6 Cultural Resources A visit to the North Carolina State Historic Preservation Office (SHPO) revealed no historic properties or archaeological resources within the project limits. KCI submitted a formal request for review of the site to SHPO. The office responded that they were not aware of any cultural resources that would be affected by the restoration project (see Appendix 2). 2.7 Potential Constraints As part of the CE documentation process, a limited Phase I site assessment was conducted to verify whether the site was listed in any state or federal environmental databases such as hazardous waste sites or underground storage tanks. The site was not identified in any databases and a summary of the limited Phase I report is included in the CE report. In addition, the project site was examined for any potential hindrances to a successful restoration project. The evaluation focused on hazardous materials, utilities, restrictive easements, and the potential for hydrologic trespass.

The parcel lies within both Orange (Pin# 0800-06-2560) and Durham (Pin# 0800-01-06-9809) counties. 2.7.2 Site Access The site is reached from Mt. Moriah Road as shown in Figure 1. Legal access is guaranteed with an - ingress/egress easement from Mt. Moriah Road to the northwestern corner of the conservation easement - boundary. 2.7.3 Utilities A search was completed to investigate any utilities present within the project site and none were found. 2.7.4 FEMA / Hydrologic Trepass . The property is located within the 100-year floodplain of Upper New Hope Creek as determined by the . Federal Emergency Management Agency (FEMA). As shown in Figure 4, the entire project site boundary is located in Zone AE. There will be no hydrologic trespass on any bordering properties. • 3.0 PROJECT SITE WETLANDS • The project site exists on the floodplain of New Hope Creek. The land has long been used for agriculture and has been drained with an extensive ditch network. The existing site conditions are shown in the project photographs (Appendix 3). 3.1 Jurisdictional Wetlands Existing wetlands were delineated in August 2005 using the methods described by the US Army Corps of • Engineers (USACE 1987). The delineation forms used for the project site are available in Appendix 4. . The wetland boundaries are shown in Figure 5 and were approved by the USACE as the existing jurisdictional wetlands (Appendix 5). . 3.2 Hydrological Characterization The site hydrology has been greatly affected by a series of ditches that all drain to New Hope Creek. The existing hydrologic conditions are shown in Figure 6. a Project Streams and Ditches There are no streams that flow directly through the project site. Upper New Hope Creek forms the eastern boundary of the project and the entire site eventually drains to this stream. There is a series of major and minor drainage ditches that run along and throughout the site. Ditches #1 and #2 are two large ditches that are each approximately one foot deep and they carry water from a small subwatershed that drains directly to the site. Ditch #3 drains water through the center of the site and diverges into Ditches #4 and #5 before all of this drainage exits via Ditch #6. Running along the southern boundary of the project boundary, Ditch #6 provides the major outlet for the site. Ditch #7 currently allows excess water . to drain from the eastern portion of the site. Ditch #9 runs along the northern site boundary and drains a small subwatershed to New Hope Creek. When water levels in New Hope Creek rise high enough to cause backwater into Ditch #9, this flow travels into Ditch #8, which during large flood events appears to flow in either direction as water levels fluctuate, although it is bordered by a 2-foot benn on the southern bank. When Ditch #9 experiences enough flow to exceed its banks, the excess is carried through the site by Ditch #3. However, another 2 to 3-foot berm has been constructed from the spoil remains of Ditch #9 that prevents this ditch from flooding except during extreme events. Ditches #10 and #11 are small • sloughs from Ditch #9 and frequently remain ponded. During larger flooding events, backwater from 7 ?? . New Hope Creek travels down Ditch # 12. Ditch # 13 carries drainage down from the eastern side of the property. Smaller minor ditches are distributed throughout the site at approximately 50 feet apart, which contribute to a significant loss of water from the site as well. Project Wetlands The site is located on an expansive and active floodplain of New Hope Creek. Moving west from the stream, the site slopes downward at approximately 1% from the levee position of the creek to a lower . floodplain position in the center of the site. This central portion is flat extending to the north, south and west to the valley walls on the site. . Existing Piedmont Bottomland Hardwood wetlands are found in some of the forested areas of the project site. In the northern part of the site, drainage from the north forms a wetland in a depressional area that ponds consistently. The drainage from this wetland leads to another small wetland approximately 200 . feet south in a small stand of hardwood trees. Another wctland exists toward the southern end of the site and Ditch #5 currently nuns through this section. A Floodplain Pool community is found in the southeastern portion of the project site. This wetland . experiences flooding for a large part of' the year. Several minor ditches from the eastern half of the property flow into this wetland and excess drainage is able to exit via Ditch #7. . All of the existing wetlands on the site receive occasional inputs from New Hope Creek flood events. . However, ditches carry water away from all of the wetlands and reduce the amount of total hydrologic input that remains on-site. Confirmation of'Riverine Condition (5-yewr.Jloodplain) FEMA originally used a HEC-2 model to determine flood elevations for New Hope Creek. KCI obtained this existing flood model and imported it into HEC-RAS. Once the model was calibrated to match the . results calculated with HEC-2, it was used to analyze the flood frequency at the Brown Site. In its previous analysis, FEMA provided flood elevations for 10, 50, 100, and 200-year flood events. In order to develop elevations for more frequent flooding events, a Log Pearson III flood frequency analysis . was used to estimate discharges for 1, 2 and 5-year events. Because there is no stream gauge available at the project site, we used peak annual streamflow data from 1983 to 2004 from the nearest United States Geologic Survey (USGS) stream gauge on New Hope Creek, Station 02097314 (approximately six miles . southeast of the Brown Farm). A log-log linear equation was then created with an R'` of 0.99 to relate the . discharge at the gauge to the discharge values known for New Hope Creek. This relationship was used to estimate discharges for more frequent flood events at the project site. Based on results from this method, the elevation for a 5-year flood event was 256.3 feet at the upstream portion of the site and 255.38 feet at . the downstream end of the site. Using these figures, the entire site would be inundated excluding only the spoil piles that reach 258 feet along Ditches #8 and #9. . An analysis was also completed to look at how often a flood event would reach the site. Using the same procedure as above, flood waters are predicted to move onto the site during a 1.1-year flooding event. At this point, the model indicates that water will enter the site from below at an elevation of approximately 253 feet. During a 1.2-year event, the site is predicted to flood from both the northern and southern . edges. With an event of this magnitude, the floodwaters are projected to enter the site from the north at an elevation estimated at 254.5 feet. Based on this analysis, flooding events are a significant hydrologic input to the project site. ? 11 3.2.1 Groundwater Gauges High groundwater has been reported historically for the site and occurs seasonally at or near the surface in the surrounding natural areas. The project site has a high water table, because of its level location along a large floodplain. The groundwater within the project site is being evaluated by monitoring the water level with three on-site HOBO recording pressure gauges. Three gauges were installed at the site in early 2006 and the locations are shown in Figure 6. The gauges were programmed to measure water levels twice daily at 12-hour intervals. 3.2.2 Hydrologic Budget for Restoration Site Existing Conditions Existing site hydrology was modeled by developing an annual water budget that calculates water inputs and outputs in order to calculate the change in storage on a monthly time step (Appendix 6). In order to set up the water budget, historic precipitation data were obtained from the North Carolina State Climatic Office. The nearest weather station to the Brown Site is Station 312515 in Durham, North Carolina. This station is located approximately 5.5 miles northeast of the project site. Monthly precipitation totals from the entire period of record (1899-2005) were reviewed and three years were selected to represent a range of precipitation conditions: dry year (1941), average year (1956), and wet year (1975). Potential inputs to the water budget include precipitation, groundwater, and surface inputs. For precipitation, the data from the three selected years were used in the budget. Groundwater input likely exists, but was considered negligible in comparison to the magnitude of surface and precipitation inputs. Surface water input was calculated using the USDA Soil Conservation Service (SCS) runoff curve number equation (1986). The results for this equation were computed using the US Army Corps of Engineers Hydrologic Engineering Center Hydrologic Modeling System (HEC-HMS). Outputs from the site include potential evapotranspiration (PET), groundwater, and surface water outlets. PET was calculated by the Thornthwaite method using mean monthly temperatures determined from the chosen years of record: 1941, 1956, and 1975. Groundwater represents losses from the site due to downward seepage through the soil profile and was assumed to be 2x10-6 ft/min (1.04 inches per month), which is typical of low permeability soils associated with wetlands. A substantial amount of water is also lost through the existing ditches on-site. A DRAINMOD model was set up to simulate the effect of the existing drainage network on wetland hydrology. The program evaluated 40 years of available precipitation data and produced the annual loss due to the ditches. The annual loss was then averaged on a monthly basis for dry, average, and wet years. Once the inputs and outputs were determined, a net monthly total was calculated in inches and used to estimate a yearly water budget. The model assumes unsaturated conditions at the beginning of the year. A maximum wetland water volume of 5.4 inches was calculated based on the specific yield of 0.15 for 36 inches of Wchadkee soil in order to analyze conditions in the upper three feet of the soil profile. The resulting hydrographs for the average, dry, and wet years show a seasonal pattern. The model shows that the majority of hydrologic inputs to the site come during the rainy spring months. The site begins to lose saturation in the upper twelve inches in the summer months. The late fall sees an increase in hydrologic inputs again. The dry year shows very little hydrology overall. The water budget does predict that wetland hydrology would exist in the average and wet years. However, this trend does correspond to conditions observed on-site and indicates that the model is not entirely representative of the true site conditions. Groundwater gauges on the site since early 2006 show large fluctuations in the data with the site at times experiencing hydrology below or at jurisdictional levels. The US Army Corps of Engineers 12 r r r r performed a wetland determination at the site on February 1, 2006 and verified that apart from in the 3.32 acres of existing wetlands the site does not have adequate jurisdictional hydrology (sec Appendix 5). r r Proposed Conditions r A second water budget was developed to analyze the effect of restoration actions on the site hydrology. The loss of water from the existing ditches was removed from the budget, because these ditches will be r filled. To estimate the impact from recreating wetland microtopography, an additional two inches of r hydrologic capacity was added to the calculations. Based on these changes, the budget shows a noticeable increase in the spring. In particular, the wet year has wetland hydrology throughout almost the r entire year. The dry year does not show much change trom the existing to proposed budget, which r indicates that during a drought year the wetland may not experience much saturation. r One factor not taken into account in the annual water budget calculations is the effect of flooding. Tile r flood analysis described in Section 3.2 predicts that the site will experience frcqueut flooding events. r Based on the existing conditions, these floodwaters would not be retained on-site and would instead drain out through the series of ditches. Under proposed conditions, the input from these flooding events would r be able to remain on-site, because of' the small depressions and rises associated with recreated wetland r microtopography. r 3.3 Soil Characterization r A soils investigation was conducted by a certified soil scientist from KCf to determine the extent and r distribution of the hydric soils on the site and to classify the predominate soils to the soil series level. The investigation consisted of delineating the hydric soil boundaries with pink flagging in accordance with the r US Army Corps of Engineers (1987). Areas that were identified as possible hydric soil slapping units r were surveyed at a higher intensity until the edge of the mapping unit was identified. The boundary of the hydric and non-hydric soil mapping units were then followed by continual sampling and observations as r the boundary line was identified and delineated. In those areas where the boundary was found to be a r broad gradient rather than a distinct break, microtopography, landscape position, soil textural changes, r redoximorphic features, and depleted matrices were additionally considered to identify the extent of the hydric soils. r To develop a detailed soils map, several soil borings were advanced on the site in the general hydric soil areas identified by landscape position, vegetation and slope. Once the hydric soil borings were identified, r the soil scientist marked the point and established a visual line to the next auger boring where again hydric soil conditions were confirmed by additional borings. The soil scientist moved along the edges of the mapping unit and marked each point along the line. To confirm the hydric soil mapping unit, soil borings were advanced to a depth of 50 inches. The soil profile descriptions identified the individual horizons in the topsoil and upper subsoil as well as the depth, color, texture, structure, boundary, and . evidence of restrictive horizons and redoximorphic features. The extent of the mapped hydric soils is shown in Figure 5. r The project site has been in agricultural production for approximately 100 years, but no Prior Converted (PC) wetland determination has been made oil the site by the USDA Natural Resources Conservation r Service (NRCS). r . 3.3.1 Taxonomic Classification The project soils were classified as Wchadkce (tine-loamy, mixed, active, nonacid, thermic Fluvaqucntic Fildoaquepts) with inclusions of' Chewacla (fine-loamy, mixed, active, thermic Fluvaqucntic Dystrudepts). r r r r 13 3.3.2 Profile Description The Orange and Durham County Soil Surveys classify all the soils underlying the site as Chewacla. However, this classification was inconsistent with the observed soil conditions at the site. A detailed soils investigation by a KCI soil scientist identified Wchadkec soils as occupying the central portion of the site where restoration will take place. This detailed soils investigation was conducted by augering numerous soil borings across the site in areas identified by landscape position, vegetation, and slope followed by the preparation of a soil map that identified the extent of each soil mapping unit. The resulting distribution of soils on-site is estimated to be 75°/, Wchadkec and 25% Chewacla. The Wchadkec and Chewacla soils are defined as hydric soils due to saturation for a significant period during the growing season and they are listed on the federal, state and county hydric soils lists (USDA, SCS 1976 and USDA, SCS 1977). The soils in the north-central portion of the project site do not have hydric features until a depth of approximately 18-24 inches. This is likely caused from overwash sediment fi-om flooding events that have accumulated on top of the Wchadkec soil below. A detailed description of all of the soil profiles by a KCI soil scientist is provided in Appendix 7. The Chewacla soils consist of very deep, moderately permeable, somewhat poorly drained soils on floodplains along bottoms, creeks, and rivers. The soil is produced from recent alluvium washed from soils formed in residuum from schist, gneiss, granite, phyllite, and other metamorphic and igneous rocks. They occur on nearly level floodplains along streams that drain from the mountains and the Piedmont. The Wchadkec soils are very deep and very poorly drained and arc found on nearly level floodplains along streams that drain from the mountains and the Piedmont. The Wehadkcc soils commonly occur with Chewacla soils. They are more poorly drained, darker in color, and more intensely mottled than the Chewacla soils (USDA, SCS 1976 and USDA, SCS 1977). 3.3.3 Soil Properties The physical properties for Wehadkcc and Chewacla are identified in Table 4.

The site has been under continuous production for the past 100 years. A series of ditches exist throughout the agricultural field. Two large ditches direct water around and/or through the site while many smaller ditches channel now to the larger drainage network. There are several trees growing in places among the agricultural fields. There is a line of trees running from north to south and within this grouping of trees there arc 14 Reference Site, Durham County, NC ORANGE D RHA? - COUNTY O ,4 C •r < _ rJ ? 7 Project Site ?/ / Reference - + Wetland I Garrett Rd - s PIP _. - ?- 5-501 z®?

Piedmont Bottomland Hardwood Forest - 1.2 acres On the northern edge of the project site, there is an established Piedmont Bottomland Hardwood Forest community. There are also two other small wetlands of this community type in the center of the site as well as along the southern edge. These wetlands experience seasonal inundation and have had standing water during recent site visits. There is a diverse mixture of hardwood species, which include red maple (Ater rubrum), sugarberry (Celtis laevigata), sweetgum (Liquidambar styraciflua), green ash (Fraxinus pennsylvanica), river birch (Betula nigra), deciduous holly (Ilex decidua), and American elm (Ulmus americana). Floodplain Pool- 2.1 acres This community exists along the southern border of the project site and sits in a depression that is lower than the rest of the project site. The wetland is saturated much of the year and contains mature vegetation such as green ash (Fraxinus pennsyh,anica), river birch (Betula nigra), red maple (Aces rubrum), and American elm (Uhnus americana). Nonnative Plant Species The site has also been invaded by several non-native plant species. Populations of Chinese privet (Ligustrum sinese), Japanese honeysuckle (Lonicera japonica), and multiflora rose (Rosa multiflora) inhabit portions of the site. 4.0 REFERENCE WETLANDS The reference wetland is located approximately 0.8 miles from the Brown Site. It is also within the floodplain of New Hope Creek and is downstream from the project site. The property is owned by the County of Durham and is included in a larger area of land protected as the New Hope Creek Bottomlands. The site location is shown in Figure 7 and photographs of the reference site are seen in Appendix 8. KCI performed a wetland determination at the reference site. The USACE data sheets used for this procedure are in Appendix 9. 4.1 Hydrological Characterization The site is located in the New Hope Creek Watershed as and the reference wetland watershed is seen in Figure 8. Similar to the project site, the reference wetland receives hydrologic inputs from a high groundwater table and seasonal flooding from New Hope Creek. Within the reference wetland, there are many physical markers of wetland hydrology. There are buttressed trunks, sediment marks on trees, and drainage patterns. 4.1.1 Gauge Data Summary The groundwater within the reference wetland will be evaluated by monitoring the water level with an on- site HOBO recording pressure gauge. Data from this gauge will be compared to gauges at the restoration areas. The gauge will be programmed to measure water levels twice daily at 12-hour intervals. The data will be downloaded periodically and evaluated to determine the depth and duration of the groundwater level on the reference site. The reference wetland gage was installed in early 2006 and its location is shown in Figure 9. 4.2 Soil Characterization The soil type as described in the Soil Survey of Durham County is shown in Figure 10 (USDA, SCS 1976). According to the soil survey, the soil type is Chewacla and Wehadkee series.

The extent of the community type and the surrounding land uses are shown in Figure 11. 4.3.1 Community Description The trees within the reference wetland include a variety of hardwood species such as red maple (Acer rubrum), green ash (Fraxinus pennsvlvanica), sweetgum (Liquidambar styraciflua), river birch (Betula nigra), sycamore (Platanus occidentalis), American elm (Ulmus Americana), slippery elm (Ulmus rubra), American hornbeam (Carpinus caroliniana), and painted buckeye (Aesculus sylvatica). 5.0 PROJECT SITE RESTORATION PLAN 5.1 Restoration Project Goals and Objectives This project proposes to improve water quality and expand wetland habitat by restoring agricultural land to a functioning riverine wetland ecosystem. Currently, the site is used for harvesting hay and occasional grazing, but it is located directly within the floodplain of New Hope Creek. This important water body contains unique aquatic habitat both upstream and downstream of the project site. New Hope Creek is listed as an impaired water body under the draft 2004 303(d) list for North Carolina starting approximately 2.4 miles downstream of the project site at the confluence with Sandy Creek. This segment of stream has impaired biological integrity from urban runoff and storm sewers (NCDENR, DWQ 2005a). Restoring this wetland will allow the site to retain a greater amount of floodwaters from New Hope Creek. Recent development in the New Hope Creek Watershed has increased the storm surge associated with precipitation events. Flood attenuation will increase by removing ditches that drain the site. The restored wetland will also provide water quality benefits by acting as a buffer to New Hope Creek from upstream agricultural and residential uses. These restoration activities will reduce both point and non- point source pollutants to the system and improve aquatic and terrestrial habitat. An overview of the mitigation type and extent at the project site is given in Figure 12. Current pastureland with drained hydric soils will be restored to wetland. Existing wetlands will be enhanced by improving the hydrology and vegetation. Surrounding upland areas on the site will be preserved to recreate a functioning ecosystem. The acreage in Table 5 below provides an overview of the restoration and enhancement wetland areas. Table 5.

The area to be restored is within the active 5-year floodplain of the New Ilope Creek and will receive inputs from numerous flood events. Restoration will focus on filling existing ditches, removing till and overburden, and creating wetland microtopography to retain floodwaters and restore wetland hydrology. Wetland-specific hardwood species will be planted to establish hydrophytic vegetation. . 5.1.2 Target Wetland Communities The main target community for the restoration area is a Piedmont Bottomland Hardwood Forest as described by Schafale and Weakley (1990). This wetland type has a canopy dominated by tree species such as tulip poplar (Liriodendron tulipkra), swectgum (Liyuidambar stvraci/lua), cherrybark oak (Quercus p(Woda (jalcala var. pagodae#)Iia)), swamp chestnut oak (Q. rnichauxii), American clm (Ulmus Americana), sugarberry (CcItis laevigatca), green ash (Fraximrs pennsylvanica), loblolly pine (Pines laeda), shagback hickory (Carla ovata), and bitternut hickory (Carya cor(Ii/ormis). Typical understory trees include American hornbeam (Carpinus caroliniana), red maple (Acer rubr•um), flowering dogwood (Cormr.s flori(Icr), American holly (I/ex opaca), and common pawpaw (Asimina triloba). Common shrubs are often species such as painted buckeye (Aesculu.Y svlvatica) and American strawberry -bush (Evonymus americanar). Invasive species such as Virginia dayflower (Commclina virginica), Japanese honeysuckle (Lonicera japonica), Japanese grass (Microslegium vimineum), and Asian spidcrwort (Mur(lannia keisak) have the potential to invade this community type. The typical Piedmont Bottomland Hardwood community is flooded at least occasionally. Bottomland Forests are believed to form a stable climax forest with uneven-aged canopy with primarily gap phase regeneration (Schafale and Weakley 1990). In the existing wetlands, there is also a large Floodplain Pool community that will be enhanced. Schafale and Weakley describe this habitat as being found in depressions in abandoned river channels on floodplains in the mountains and the Piedmont. They typically hold standing water much or all of the year. In the center of these pools, there may not be any higher plants and aquatic plant species may dominate instead. The edges feature aquatic and wetland vegetation with species such as royal fern (Ostnunda regalis var. speclabilis), handsome sedge (Carex.lbIlicu/ala), fringed sedge (C. crinita), white edge sedge (C. debilis), broadwing sedge (C. alata), false nettle (Boehmeriar cylindrical), water-pepper (Polvgonrrnr cespitosum), marsh scedbox (Ludwigia pa/ustris), and Sphagnum spp. Shrubs such as hazel alder (Alms serrrdala) may occur on the edge (Schafale and Weakley 1990). 5.2 NEC-RAS Analysis The Brown Site is located entirely within the 100-year floodplain of New Hope Creek (Zone AE). FEMA originally used a HEC-2 model to analyze the flooding dynamics along New Hope Creek. KCI obtained . this HFC-2 model, brought the data into HEC-RAS, and calibrated the converted model to match the results produced by the original HF,C-2 output. . 5.2.1 No-rise, LOMR, or CI,OMR With this HEC-RAS model, we modified the two cross-sections that go through the project site to reflect the changes in elevation from filling the ditches. Based on this analysis, KCI does not predict a rise in 23 base flood elevations. The modified IiEC-RAS model showed a rise less than or equal to 0.01 feet. A No-Rise Certification letter explains these results in Appendix 10. 5.2.2 Hydrologic Trepass There will be no hydrologic trespass to any landowners upstream or downstream of the Brown Site. The planned actions will not encroach on any neighboring land and any increased flooding is anticipated to stay within the project limits based on the flood analysis described in previous sections above. 5.3 Hydrological Modifications Hydrologic modifications will focus on restoring surface water retention to this wetland system. Currently, existing ditches and berms force water out of the system and prevent surface water from remaining on-site and recharging the groundwater. Hydrologic restoration and enhancement will focus on filling in these ditches that were constructed to drain the historic wetlands for agriculture. The restoration will also involve removing or breaching berms that currently force water into the ditches. Together these actions will allow surface and floodwaters to have greater access to the wetlands. Three level spreaders will also be constructed across the project site to allow hydrologic access across the entire area as would occur in a natural wetland. The modifications that will take place are displayed in Figure 13. 5.3.1 Narrative of Modifications Hydrologic modifications will focus on restoring historic wetland hydrology by removing ditches and berms that restrict flow from reaching and remaining on-site. Three level spreaders will be constructed to reconnect the hydrology across the entire site. Wetland restoration and enhancement are planned for the project site and described below. RNerine Wetland Restoration - 24.58 Acres Wetland restoration will take place on 24.58 acres of Wehadkee soils currently used for hay production and grazing. The hydrologic restoration will focus on removing ditches and berms. Ditches IN, #2, 93, #4, #7, #8, #12, and #13 will be tilled. Berms that run along the southern edges of Ditches #8 and #9 will be removed where feasible; mature trees exist in places along the berm and will be left in place. In order to block the remaining flow from minor ditches that run primarily north to south, microtopography will be oriented perpendicular (i.e. southwest to northeast). This grading method will effectively create small depressions and rises across the landscape while stopping the flowpath From these ditches. Using this procedure will also allow some of the existing grasses to remain in place and stabilize the system in the case that a extreme flooding event from New Hope Creek were to occur shortly after construction. Fences are already in place to restrict cattle access to the restored wetland. In some locations, up to six inches of fill/overburden will be removed from the top surface of the soil. This layer to be removed is a combination of overwash sediments that have accumulated from flooding events and spoil remains fi-om the extensive series of ditches that were constructed on the site. Three level spreaders will be installed throughout the project site as displayed in Figure 13. These features will spread across the site in several places and are designed to mimic the elongated flowpath in a natural wetland. One will begin at a point just upstream of where Ditch #9 drains into New I lope Creek and wrap around to the central portion of the site. Another level spreader will take the flow that is coming from Ditch #1 and pull this across the site to the cast. A final level spreader will be installed from the north-central portion of the site and allow water to seep toward southeast. RNerine Welland Enhancement - 3.32 Acres Currently the existing wetlands on-site have adequate wetland hydrology and most have an intact hardwood canopy. However, these wetlands have been modified by ditches throughout the site that drain a significant amount of water. The hydrology to these wetlands will be enhanced by filling Ditches #3, 24 i —— — — �� e � 4. jy9 � J F - . #4, #7, and #8. The only remaining outlet that will allow water to leave the site will be through a stabilized ditch plug outlet where Ditches #4 and #5 enter Ditch #6. 5.3.2 Scaled Schematic of Modifications A diagram of the proposed restoration and enhancement actions is shown in Figure 13. It describes the activities that will restore the site. 5.4 Natural Plant Community Restoration Restoring natural vegetation will focus on establishing native wetland hardwood species in the entire wetland. The majority of the area will receive species consistent with a Piedmont Bottomland Hardwood Forest community. Enhancement areas will be planted with targeted hardwood species to increase species diversity. Populations of invasive species have also been identified and will be eliminated as much as possible. Restoration Plant Community The restoration wetland will be planted as a Piedmont Bottomland Hardwood Forest Community using the species described below. Approximately 436 trees per acre (10' x 10' spacing) will be planted to achieve a mature survivability of three hundred twenty (320) trees per acre. The site will be planted with 1-gallon container stock instead of bare root trees to improve the overall rate of survivability. Plant placement and groupings will be randomized during the restoration in order to create a more natural appearance. Woody vegetation planting will take place during dormancy. Tree species to be planted may consist of the following: Green ash . Fraxinus pennsylvanica FACW Tulip poplar Liriodendron tulipfera FAC Water tupelo Nyssa aquatica OBL Laurel oak Quercus laurifolia FACW Overcup oak Quercus lyrata OBL Swamp Chestnut oak Quercus michauxii FACW- Cherrybark oak Quercus pagoda FACW Willow oak Quercus phellos FACW- The restoration area will be divided into two planting zones in order to target species to site conditions. These zones are shown in Figure 14. Zone A will be planted with tree species with obligate or facultative-wet designation and could include green ash (Fraxinus pennsylvanica), water tupelo (Nyssa aquatica), overcup oak (Quercus lyrata), swamp chestnut oak (Q. michauxii), and willow oak (Q. phellos). Zone B will be planted with facultative species such as green ash (Fraxinus pennsylvanica), tulip poplar (Liriodendron tulipfera), cherrybark oak (Quercus pagoda), and laurel oak (Q. laurifolia). Welland Enhancement Enhancement plantings will consist of hardwood species with a obligate or facultative-wet designation, because these existing wetlands already experience a frequent level of saturation. The species will likely consist of the following: Water tupelo Nyssa aquatica OBL Laurel oak Quercus laurifolia FACW Overcup oak Quercus lyrata OBL 26 In the Bottomland Hardwood Community, the wetland will be enhanced with these species listed above at a density of approximately 100 to 200 trees per acres. The Floodplain Pool Community will be planted at the same density, but the trees will be placed only in the outer fringes of the site where ponding is less frequent. Invasive Species Management The Brown Site has been affected by several nonnative plant species. One of the most significant invaders is Chinese privet (Ligustrum sinense); large thickets of the plant occupy the edges of the proposed restoration site. Japanese honeysuckle (Lonicera japonica) and multiflora rose (Rosa multiflora) have also spread into parts of the site. These species will be marked and treated with a glyphosate herbicide. Japanese grass (Microstegium vimineum) is also a pervasive nonnative plant in this area. As much native grass cover will be retained during the construction process as possible to minimize the amount of bare soil available to invasive plants. 6.0 PERFORMANCE CRITERIA A monitoring program will be implemented to observe the progress toward achieving mitigation goals and objectives within the restored wetland areas. The site will be deemed successful once wetland hydrology is established and vegetation success criteria are met. 6.1 Hydrology Groundwater elevations will be monitored to evaluate the attainment of jurisdictional wetland hydrology The reference wetland will also be monitored using the same procedures for comparative analysis. Monitoring Procedure Verification of wetland hydrology will be determined by automatic recording well data collected within the project area and reference wetland. Automatic recording gauges will be established within restoration areas at a density of one automatic well per four acres. Daily data will be collected from the automatic gauges over the 5-year monitoring period following wetland construction. Restoration Success Criteria Wetland hydrology will be considered established if well data from the site indicate that the water table is within 12 inches of the soil surface for 5% of the growing season during normal weather conditions. The growing season was taken from NRCS climatic data for Durham County, which has the closest meteorological station to the project site (Station NC312515). According to the NRCS, the growing season is considered to be the period with a 50% probability that the daily minimum temperature is higher than 28° F. The growing season for Durham County extends from March 24 to November 1 for a total of 222 days (USDA, NRCS 2003). Based on this growing season, success will be achieved at the project site if the water table is within 12 inches of the soil surface for 11 days or more during the growing season. 6.2 Vegetation The success criteria for the planted species in the restoration areas will be based on survival and growth. Beginning at the end of the first growing season, KCI will monitor vegetation for five years following the planting. Monitoring Procedure Permanent monitoring plots (10 by 10 meters) will be established in the wetland restoration areas at a density that will ensure 2% coverage of the total restoration acreage. Plots will be systematically located 28 to ensure even placement. Data will be collected at each plot for: total number of stems, species, percent survival, height, estimated percent cover of all species, and evidence of insects, disease or browsing. Restoration Success Criteria Survival of planted species must be 320 stems/acre at the end of five years of monitoring. Non-target species must not constitute more than 20% of the woody vegetation based on permanent monitoring plots. 6.3 Schedule / Reporting Monitoring data will be collected annually for a period of five years or until success criteria are achieved. Annual reports will be submitted to NCEEP and will document the monitored components of the restoration plan (hydrology and vegetation) and include all collected data, analyses, and photographs. Restoration of wetlands involves interpretation of collected information to devise a strategy that will ultimately lead to a functional ecosystem. Minor variations in the results can be anticipated due to unknown site conditions, inputs from outside the restoration site, regional climatic variations, or acts of God, etc. Correspondingly, nurturing the site with regular management activities is considered necessary to ensure that the goals and objectives of the project are met. These activities will be conducted throughout the year and may include invasive species control or other management activities. If the monitoring identifies failures in the project site, a remedial action plan will be developed to investigate the causes of the failure and propose actions to rectify the problem. 29 7.0 REFERENCES Environmental Laboratory. 1987.

Soil Profile Description • Detailed Soils Investigation and Mapping for the Brown Site For the past 100 years, the soils on the Brown site have been altered by a ditch/spoil drainage system to • prepare the land for cultivation. The primary ditch/spoil system to the north borders the site and depending on the size of the storm, diverts floodwaters either back to New Hope Creek or onto the site. During larger storm events, floodwaters pass through the ditch/spoil system via diversions conveniently a placed at regularly spaced intervals and then flow overland across the site through the secondary lateral surface water ditches, which in turn arc connected to the primary outlet ditch/spoil system to the south. The ,ccondary lateral ditches arc spaced approximately every 50 ft and the spoil was spread between the ditches to shed water to the drainage system. The landscape alterations have created a complex hydric soil mosaic on the landscape between the ditches and appear to create conditions necessary for overwash to be deposited at various locations on-site during storm events. It is apparent that these historic events have • reshaped the floodplain and the hydric soil-forming processes on the site, but have not altered the forested areas to the north or the south that arc still in-line with the natural flood water flow direction. The Orange/Durham County Soil Survey has classified the soils underlying the site as Chewacla loam. Based on field results, KCi Associates of North Carolina, P.A. (KCI) has remapped and reclassified the • soils as primarily Wehadkec (Fine-loamy, mixed, active nonacid, thermic Fluvaqucntic Endoaquepts). Ill areas of frequent overwash, the soil is classified as a Wehadkec variant, because of the sediment . deposition and/or till from man-made alterations. Some pedons have recent layers of overwash up to 20 inches thick that are loamy and variable in color as indicated by the range of characteristics for the Ap and A horizons of the Wehadkec series. The Wehadkec variant classification is transitory between the Wehadkec soils and the wetter phase of the Chewacla series. The Wehadkec series is listed as a hydric • soil due to saturation for a significant period during the growing season and is in accordance with the federal, state, and county hydric soils list. This reclassification is based on our findings obtained from a detailed soils investigation. This detailed soils investigation was conducted by augcring numerous soil borings across the site and classifying the soils in accordance with Soil Taxonomy. To verify the soil mapping units, five soil pits 18 inches deep w followed by auger borings were advanced on-site and detailed soil descriptions were prepared for the vertical soil profile (sec the following figure, Soil Descriptions with Soil Pit Numbers). These five soil profile descriptions share similar characteristics that have influenced the reclassification. The soil profile descriptions were prepared to highlight the visible soil alterations due to overwash, man-made ditching system and the consequent spoil associated with the drainage that is identified in the surface horizons on . the site. This ditching network is also observed in the 2002 aerial photograph. The soils have primarily been buried by 10 to 17 inches of loamy textured materials that arc variable in color, but occur within the range of characteristics of the Ap and A horizons. Furthermore, a more detailed analysis of the stratification of the overwash was conducted to show the redoximorphic features that developed due to the horizontal stratification. The Bw horizon is variable in color and the C horizon is a massive compacted horizon that occurs above the buried solum. The 10 to 17 inches of soil material is a result of overbank flooding and excavated spoil materials spread on the site. The profile descriptions of the 10-17 inch horizons indicate the development of the following due to a fluctuating water table: soil color (Bw), iron concretions greater than 3mm within the upper 3 inches, and redoximorphic features. The site is, however, sufficiently drained to prevent low chroma colors from forming. The asterisk that appears on the following soil descriptions indicates stable horizons that appear to have been developed naturally over time by natural soil-forming processes. The horizons above the asterisk appear to be overburden, which have multiple stratified horizons with little or no structure and differing colors and textures. Based on the information presented for the stable horizons designated with an asterisk, these soils show relic saturation and relic hydric soils below the overwash/spoil. Additionally, during the winter and spring the soils have stored sufficient moisture to show a chroma 2 matrix across the site at 10 to 12 inches below the surface. However, during the summer and fall when the drainage system and evapotranspiration are at their peak these chroma 2 matrix colors become a chroma 2.5 or 3. Steven F.

The project limits include cross . sections labeled 1928 through 1929 and in the HEC-RAS model; the project includes Section number 192819 to Section number 193912. The HEC-2 model was received from the floodplain manager for the City of Durham. . A Duplicate Model was generated in HEGRAS to perform this study. The Duplicate Model is the original . HEC-2 model provided to KCI by the City of Durham. The HEC-2 model was imported into HEGRAS and the published 100-year Base Elevations (BSE's) were duplicated by the model. Detailed field survey data was . taken within the project area and will be reflected in the Conditional Model. The boundary conditions and discharge data in the models are based on the original model. Due to this data being available, a hydrological analysis was not performed. The HEGRAS 3.1 computer program was used to • perform the hydraulic analysis. A Conditional Model was generated in HEC-RAS by revising the existing cross sections at stations 192819 and station 193912. This Conditional Model serves as the baseline condition for the no-rise analysis for the . proposed wetland restoration. The Proposed Model reflects the design of the wetland restoration. Three 1'-0" ditches will be filled-in and . this change is reflected in the two cross sections through the project at station 192819 and station 193912. The results of the analysis indicate that the wetland restoration project will have no significant impact on the . cross sections of the New Hope Creek Floodplain and as a result will not impact the base flood elevations .

Name of project: Brown Farm Wetland Restoration Site 2. T.I.P. Project Number or State Project Number (NCDOT Only): 3. Property Identification Number (Tax PIN): 0800-06-2560 (Orange Co.)/ 0800-01-06-9809 (Durham Co.) 4. Location County: Orange and Durham Nearest Town: Durham Subdivision name (include phase/lot number): Directions to site (include road numbers/names, landmarks, etc.): Take I-40 to State Hwy 15-501. Head northeast on 15-501 and turn left on Mt. Moriah Rd. The Brown Farm is located approximately one mile out on Mt. Moriah Road on the right. The entrance is at a metal gate where there is a small ridge that looks out over the project site below. 5. Site coordinates (For linear projects, such as a road or utility line, attach a sheet that separately lists the coordinates for each crossing of a distinct waterbody.) Decimal Degrees (6 digits minimum): 35.9670 ON 78.9977 °W 6. Property size (acres): 46.13 acres 7. Name of nearest receiving body of water: New Hope Creek 8. River Basin: Cape Fear River Basin (Note - this must be one of North Carolina's seventeen designated major river basins. The River Basin map is available at http://h2o.enr.state.nc.us/adrnin/mgps/.) 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: The Brown Farm has been under cultivation or used for grazing for over 100 years. An extensive ditch network has allowed for agriculture despite the site's location on the New Hope Creek Floodplain. The area surrounding the project site Page 6 of 12 is experiencing rapid growth. Downstream of the project site, there is residential and commercial development expanding along the State Highway 15-501 corridor. Upstream, however, part of the project watershed is within Duke Forest, a 7,200-acre research forest owned by Duke University. 10. Describe the overall project in detail, including the type of equipment to be used: This wetland restoration project will reclaim the site as a riverine wetland. A bulldozer and/or front-end loader on tracks will be used to plug the selected channel and install a rock stabilized outlet. All work will be done on high ground when possible, but mats will be used as needed to protect jurisdictional wetlands. 11. Explain the purpose of the proposed work: The project will restore a 46.13-acre agricultural area to a Bottomland Hardwood wetland ecosystem. Existing ditches on-site do not represent natural site conditions and prevent or limit the formation of wetland hydrology. IV. Prior Project History If jurisdictional determinations and/or permits have been requested and/or obtained for this project (including all prior phases of the same subdivision) in the past, please explain. Include the USACE Action ID Number, DWQ Project Number, application date, and date permits and certifications were issued or withdrawn. Provide photocopies of previously issued permits, certifications or other useful information. Describe previously approved wetland, stream and buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project, list and describe permits issued for prior segments of the same T.I.P. project, along with construction schedules. A jurisdictional determination was requested from the USACE and approved by Todd J. Tugwell of the Raleigh Regulatory Field Office on February 1, 2006 (Action ID 200521343). A copy of this boundary plat is attached. V. Future Project Plans Are any future permit requests anticipated for this project? If so, describe the anticipated work, and provide justification for the exclusion of this work from the current application. VI. Proposed Impacts to Waters of the United States/Waters of the State It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to wetlands, open water, and stream channels associated with the project. Each impact must be listed separately in the tables below (e.g., culvert installation should be listed separately from riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts, permanent and temporary, must be listed, and must be labeled and clearly identifiable on an accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial) should be shown on a delineation map, whether or not impacts are proposed to these systems. Wetland and stream evaluation and delineation forms should be included as appropriate. Photographs may be included at the applicant's discretion. If this proposed impact is strictly for Page 7 of 12 wetland or stream mitigation, list and describe the impact in Section VIII below. If additional space is needed for listing or description, please attach a separate sheet. 1. Provide a written description of the proposed impacts: The project will install a rock stabilized outlet, which will block the flow of water out of the wetland. Plugging this ditch will improve hydrology within this existing wetland and elsewhere on the site for restoration areas. 2. Individually list wetland impacts. Types of impacts include, but are not limited to mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams, separately list impacts due to both structure and flooding. Wetland Impact Site Number (indicate on map) Type of Impact Type of Wetland (e.g., forested, marsh, herbaceous, bog, etc.) Located within 100-year Floodplain ( es/no) Distance to Nearest Stream (linear feet) Area of Impact (acres) 1 1 rock stabilized outlet Forested Yes 418 0.00115 Total Wetland Impact (acres) 3. List the total acreage (estimated) of all existing wetlands on the property: 3.32 acres 4. Individually list all intermittent and perennial stream impacts. Be sure to identify temporary impacts. Stream impacts include, but are not limited to placement of fill or culverts, dam construction, flooding, relocation, stabilization activities (e.g., cement walls, rip-rap, crib walls, gabions, etc.), excavation, ditching/straightening, etc. If stream relocation is proposed, plans and profiles showing the linear footprint for both the original and relocated streams must he included. To calculate acreage. multinlv length X width. then divide by 43.560. Stream Impact Number (indicate on ma) Stream Name Type of Impact Perennial Intermittent? ? Average Stream Width Before Impact Impact Length (linear feet) Area of Impact (acres) 1 Total Stream Impact (by length and acreage) 5. Individually list all open water impacts (including lakes, ponds, estuaries, sounds, Atlantic Ocean and any other water of the U.S.). Open water impacts include, but are not limited to fill. excavation. dredging. flooding. drainage. bulkheads. etc. Open Water Impact Name of Waterbody Type of Waterbody Area of Site Number (if applicable) Type of Impact (lake, pond, estuary, sound, bay, Impact (indicate on ma) ocean, etc.) (acres) Page 8 of 12 Total Open Water Impact (acres) 6. List the cumulative impact to all Waters of the U.S. resulting from the project: Stream Impact (acres): 0 Wetland Impact (acres): 0.00115 Open Water Impact (acres): 0 Total Impact to Waters of the U.S. (acres) 0.00115 Total Stream Impact (linear feet): 0 7. Isolated Waters Do any isolated waters exist on the property? ? Yes ® No Describe all impacts to isolated waters, and include the type of water (wetland or stream) and the size of the proposed impact (acres or linear feet). Please note that this section only applies to waters that have specifically been determined to be isolated by the USACE. 8. Pond Creation If construction of a pond is proposed, associated wetland and stream impacts should be included above in the wetland and stream impact sections. Also, the proposed pond should be described here and illustrated on any maps included with this application. Pond to be created in (check all that apply): ? uplands ? stream ? wetlands Describe the method of construction (e.g., dam/embankment, excavation, installation of draw-down valve or spillway, etc.): Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): Current land use in the vicinity of the pond: Size of watershed draining to pond: Expected pond surface area: VII. Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. 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. The proiect proposes to restored wetlands to agricultural lands that have been drained. Impacts to existing streams have been minimized in the restoration design. 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 Page 9 of 12 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. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at htti)://h2o.enr.state.nc.us/ncwetlands/stnnizide.html. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP).

The River Basin map is available at http://h2o.enr.state.nc.us/admin/maps/.) 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: The Brown Farm has been under cultivation or used for grazing for over 100 years. An extensive ditch network has allowed for agriculture despite the site's location on the New Hope Creek Floodplain. The area surrounding the project site Page 6 of 12 is experiencing rapid growth. Downstream of the project site, there is residential and commercial development expanding along the State Highway 15-501 corridor. Upstream, however, part of the project watershed is within Duke Forest, a 7,200-acre research forest owned by Duke University. 10. Describe the overall project in detail, including the type of equipment to be used: This wetland restoration project will reclaim the site as a riverine wetland. A bulldozer and/or front-end loader on tracks will be used to plug the selected channel and install a rock stabilized outlet. All work will be done on high ground when possible, but mats will be used as needed to protect jurisdictional wetlands. 11. Explain the purpose of the proposed work: The project will restore a 46.13-acre agricultural area to a Bottomland Hardwood wetland ecosystem. Existing ditches on-site do not represent natural site conditions and prevent or limit the formation of wetland hydrology. IV.

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 Page 9 of 12 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.
