To reduce flooding upstream and downstream of Raeford Road, a floodplain bench will be excavated approximately 600 feet on the left bank of Buckhead Creek. The bench will range between 70 and 130 feet wide. All work along Buckhead Creek will be performed above the ordinary high water mark. This will decrease the 25 -year water surface elevations by approximately 0.6 to 1.0 feet upstream of Raeford Road. Coventry Road This project includes installing twin - 8' x 6' box culverts to the left of the existing culverts (looking downstream). The existing culverts are in good condition and can remain in place. APPLICATION FOR DEPARTMENT OF THE ARMY PERMIT (33CFR 325) SUPPLEMENTAL INFORMATION SHEET Buckhead Creek Watershed Stormwater Infrastructure Improvement Projects at Coventry and Raeford Road Cumberland County, North Carolina Downstream of Coventry Road, a floodplain bench 40 to 70 feet wide will be excavated along both banks for approximately 400 feet. All work along Buckhead Creek will be performed above the ordinary high water mark. The primary goal of the Buckhead Creek Watershed Project is to reduce flooding risks through the watershed and to "safeguard the public welfare through the proper collection, conveyance, and storage of stormwater runoff in a non-damaging and non -life threatening manner," as described on the City's website. Block 19 Project Purpose Raeford Road to Coventry Road. Backwater from Raeford Road during the 25 -year storm currently extends approximately 3,000 feet upstream of Raeford Road into the Buckhead Creek subdivision. Based on model results, backwater from the Raeford Road system is the predominant cause of flooding at this location. Installing a floodplain bench downstream of Raeford Road would decrease the 25 -year water surface elevations approximately 0.6 to 1.0 feet upstream of Raeford Road without increasing the culvert size under Raeford Road. Coventry Road to Lake Francis. Installing two additional box culverts will provide a 25 -year level of service for Coventry Road and reduce water surface elevations for the 25 -year storm upstream of Coventry Road between 1.0 feet and 2.8 feet. The Coventry Road culvert project lowers water surface elevations approximately 1,500 feet upstream of Coventry Road and 450 feet downstream of Coventry Road. The proposed culvert will significantly reduce flooding upstream of Coventry Road, however additional improvements are required to reduce flooding downstream of Coventry Road. The culvert improvement project will include a floodplain bench on the right bank for approximately 400 feet downstream of Coventry Road. The floodplain bench reduces the 25 -year water surface elevation downstream of Coventry Road by approximately 0.9 to 3.0 feet. 2 Buckhead Creek Watershed Stormwater Infrastructure Improvement

These projects were identified in the "Buckhead Creek Watershed Study" completed by WK Dickson for the City of Fayetteville in June 2009 (Appendix Q. This permit application details the project's purpose and need, alternatives, existing conditions, environmental effects, and compensatory mitigation plan. The primary design and permitting project team members are: • City of Fayetteville — Applicant — Mary DePina, Engineering Department • WK Dickson — Consulting Engineers — project design, permitting — Tom Murray, Senior Project Manager The City of Fayetteville implemented a stormwater utility in 1995 to provide the funding for the City's stormwater infrastructure and management policies. This utility allows the City to meet the federal mandate resulting from the 1987 Clean Water Act, and to satisfy the requirements of the City's National Pollutant Discharge Elimination System (NPDES) permit, both of which are primarily related to the improvement of water quality. In 2007, the City elected to implement an additional stormwater "drainage" fee that would be utilized to maintain the existing stormwater infrastructure and fund the planning, design, and implementation of flood control projects. As part of the City's initiative to reduce flooding, the City commissioned a study of existing flooding problems in the Buckhead Creek watershed. The study identified issues and recommended improvements to reduce flooding. Buckhead Creek is located in the western portion of Fayetteville, and generally drains from north to south, ultimately discharging to Little Rockfish Creek as shown in Figure 1. A watershed study included an evaluation of Buckhead Creek from Cross Creek Mall at the upstream end of the study to approximately 1,000 feet downstream of Cumberland Road, as well as numerous drainage systems that drain to Buckhead Creek within this reach. The locations of the systems evaluated in this Study are shown in Figure 1 and Figure 2. The primary goal of the Buckhead Creek Watershed Study was to identify ways to reduce flooding risks along the Buckhead Creek floodplain. Over 70 structures adjacent to the creek are located within the FEMA 100 -year effective floodplain of Buckhead Creek. The majority of those structures are also at risk of flooding during more frequent storm events. Watershed Characteristics and History of Drainage Problems The Buckhead Creek watershed shown in Figure 1 is approximately 5.2 square miles between the upstream boundary near Cross Creek Mall and the City of Fayetteville limits near Cumberland Road.

Land use in the watershed is primarily fully developed, as shown on the Land Use Map in Appendix C. For this reason, the existing conditions land use was assumed to be the future conditions land use obtained from the City's zoning maps. Development within the watershed is approximately 50 percent residential with significant commercial areas around the headwaters, including Cross Creek Mall and along Raeford Road. North Carolina Department of Transportation (NCDOT) maintained rights -of -way (ROW), including All- American Expressway, Morganton Road, Cliffdale Road, Raeford Road, and Cumberland Road, comprise a significant portion of the watershed. Soils within the watershed predominantly fall into NRCS hydrologic soil groups A and B, as shown in Appendix C. While the watershed is located in the Sandhills region of North Carolina, the dense development in the watershed somewhat limits the natural Sandhills soil conditions, which are conducive to high levels of infiltration. A list of drainage problems in the Buckhead Creek watershed was obtained through feedback from property owners at a public meeting, questionnaires, and input from City staff. The questionnaires addressed the frequency, location, and severity of flooding. Approximately 170 surveys were completed through the online submission form or by completing and returning the paper survey. Feedback from the questionnaires and the public meeting were instrumental in identifying the flooding problem areas in the watershed that required detailed analysis. A detailed description of the existing drainage problems is included in Section 2. 1.1 Project Description Based on the results of the Buckhead Creek Watershed Study and available funding, five independent projects were selected to proceed with design and permitting. Two of the projects selected were determined to require an individual 404 Permit and 401 Certification due to wetland impacts: Raeford Road Project Raeford Road Floodplain Bench: The proposed Raeford Road Floodplain Bench would be located immediately downstream of Raeford Road. The proposed project will increase the floodplain capacity and reduce flood surface elevations through the excavation of material within the floodplain for approximately 600 linear feet along Buckhead Creek. The floodplain bench will reduce the tailwater of the Raeford Road Culvert and lower flood surface elevations upstream of the culvert. Coventry Road Project Coventry Road Culvert and Floodplain Bench: The proposed project includes installing two 8 -foot by 6 -foot box culverts on either side of the two existing box culverts under Coventry Road. The project also includes installing approximately 800 linear feet of floodplain bench along the left bank, and 400 linear feet of floodplain bench along the right bank of Buckhead Creek. This project will lower flood surface elevations for residents downstream of Coventry Road, and lower the tailwater for the Coventry Road culvert. The proposed design will provide a 25 -year level of service at Coventry Road, and will significantly lower flood surface elevations upstream of Coventry Road; this will reduce the frequency and severity of flooding for several residences along Odom Drive. Ell 1.2 Agency Coordination and Applications The City is submitting an Individual Permit application to the USACE permanently impact 0.97 acres of riparian wetland at Raeford Road wetland at Coventry Road pursuant to Section 404 of the Clean Water This action will require water quality certification from the State of NCDWQ (NCGS 143 -215) pursuant to Section 401 of the Clean Water requesting authorization to and 0.35 acres of riparian Act of 1972 (33 USC 1344). North Carolina through the Act. The purpose of this document is to provide an evaluation of five criteria: 1) purpose and need for the proposed activity; 2) alternatives analysis to accomplish the objectives of the proposed activity; 3) existing conditions in the proposed project area; 4) environmental effects from the proposed activity; and 5) compensatory mitigation plan for unavoidable impacts to jurisdictional areas. This document is intended for use by USACE and NCDWQ as the basis for determining the applicant's compliance with the Section 404 (b) (1) guidelines and other Section 404 permitting requirements, and Section 401 water quality certification. WK Dickson and the Applicant have held several meetings with USACE and NCDWQ regulatory staff. Table 1 below summarizes the pre - application agency meetings relevant to this project. Table 1. Summary of Agency Meetings Date Agencies Present Meeting Purpose May 3, 2011 USACE, WK Dickson, City of Preliminary field review of Fayetteville Jurisdictional Determination June 21, 2011 NCDWQ, WK Dickson Field review of project area August 2, 2011 USACE, WK Dickson Discussion of mitigation options for projects The proposed project will also require a sediment and erosion control permit from NC Division of Land Resources, and a LOMR from FEMA. The City of Fayetteville has not applied for these permits at the time of this application. 2.0 PURPOSE AND NEED FOR PROPOSED ACTIVITY 2.1 Project Purpose The primary goal of the Buckhead Creek Stormwater Infrastructure Improvements Project is to reduce flooding risks through the watershed and to safeguard the public welfare through the proper collection and conveyance of stormwater runoff in a non - damaging and non -life threatening manner. Raeford Road Backwater from Raeford Road during the 25 -year storm currently extends approximately 3,000 feet upstream of Raeford Road into the Buckhead Creek subdivision. Approximately 40 homes and several apartment buildings are located in the FEMA 100 -year floodplain in the Raeford Road backwater zone. To help alleviate upstream flooding, a floodplain bench will be constructed along the left and right banks of Buckhead Creek downstream of Raeford Road. Installing a floodplain bench downstream of Raeford Road will decrease the 25 -year water surface elevations by approximately 0.8 feet upstream of Raeford Road without increasing the conveyance capacity under Raeford Road. Recommendations from the watershed study include a future phase for this project that would include an additional culvert under Raeford Road to provide additional flood reductions. The floodplain culvert is not included in this permit application. Coventry Road To alleviate upstream flooding, twin 8 -foot by 6 -foot precast reinforced box culverts will be installed at Coventry Road on either side of the existing box culverts along Buckhead Creek. Installing the two additional box culverts will provide a 25 -year level of service for Coventry Road, and reduce water surface elevations for the 25 -year storm upstream of Coventry Road by between 1.9 feet and 3.5 feet. To alleviate downstream stream flooding, a floodplain bench will be constructed along the right and left bank floodplain of Buckhead Creek downstream of Coventry Road. The bench will range between 70 and 130 feet wide. The floodplain bench will reduce the 25 -year water surface elevation downstream of Coventry Road by approximately 1.0 foot. 2.2 Project Need Raeford Road As noted above, approximately 40 homes and several apartment buildings are located in the 100 - year floodplain throughout the area impacted by backwater from Raeford Road. Sixteen homes in the area upstream of Raeford Road only have a 2 -year level of service, indicating that they are flood -prone in storms larger than the 2 -year event. The elevation of Raeford Road is approximately 6 feet higher than ground elevations upstream in the Buckhead subdivision. The proposed project will reduce the 25 -year peak flood elevations by approximately 0.8 feet in the area of concern without increasing the capacity under Raeford Road. Increasing the capacity under Raeford Road may be a potential future project; however, potential project constraints include a high traffic volume along Raeford Road, numerous utilities, and the potential for increasing downstream flows. Coventry Road The existing culverts under Coventry Road currently convey the 2 -year storm event. However, stream flows overtop Coventry Road in rain events larger than the 2 -year storm, causing finished floor flooding at 4501 Coventry Road. An additional five homes along Odom Drive upstream of Coventry Road and one home on Coventry Road have property flooding during the 25 -year storm event. Coventry Road is also a key roadway for residents, school transportation, and emergency vehicles, as it provides one of the few options for crossing Buckhead Creek. The proposed project would provide a 25 -year level of service for the roadway and the residences noted above. Furthermore, the proposed project is designed to convey potentially higher future flows as a result of increasing the conveyance capacity at Raeford Road. This project is also designed to accommodate higher flows when an additional floodplain culvert is installed upstream at Raeford Road in the future. 3.0 ALTERNATIVES ANALYSIS Under the Section 404 (b)(1) Guidelines, a practicable alternative must be available to the applicant. Pursuant to 40 CFR 230.10(a)(2) practicable alternatives are those alternatives that are "available and capable of being done after taking into consideration cost, existing technology, and logistics in light of overall project purpose ". The preamble to the 404(b) Guidelines states, "if an alleged alternative is unreasonably expensive to the applicant, the alternative is not practicable ". Section 40 CFR 230.10 (a) of the Guidelines state that "no discharge of dredged or fill material shall be permitted if there is a practicable alternative to the proposed discharge which would have 0 less adverse impact on the aquatic ecosystem, so long as the alternative does not have other significant environmental consequences ". The Alternatives for the Raeford Road and Coventry Road sites have been evaluated according to how each fulfills the purpose and need, environmental concerns, construction considerations, and capital cost. The development of flood mitigation alternatives is intended to reduce the frequency and severity of flooding for as many residents of Fayetteville as possible. Flood mitigation alternatives proposed for Buckhead Creek include the following: • Infrastructure improvements, • Floodplain storage, • Peak flow attenuation, • Flood protection, and • Property acquisition. Six alternatives were evaluated for each of the Raeford Road and Coventry Stormwater Infrastructure Improvements projects. Coventry Road Project Alternative 1: Installation of twin 8400t by 6400t box culverts beneath Coventry Road and construction of a floodplain bench along the left and right banks of Buckhead Creek downstream of Coventry Road. Alternative 2: Installation of twin 8 -foot by 6 -foot box culverts beneath Coventry Road, construction of a floodplain bench along the left and right banks of Buckhead Creek downstream of Coventry Road, minimizing wetland impacts. Alternative 3: Buyout/relocation of affected homes /businesses. Alternative 4: Develop adequate up- gradient detention BMPs to reduce peak flow and downstream flooding potential. Alternative 5: Deepen and widen the existing breach downstream at Lake Francis to provide additional flood capacity. Alternative 6: "No Build" Alternative. 7 Raeford Road Project Alternative 1: Construction of a floodplain bench along the left and right banks of Buckhead Creek downstream of Raeford Road.

Alternative 6: "No Build" Alternative. 7 3.1 Evaluated Alternatives for Raeford Road Raeford Alternative 1 (preferred alternative): The construction of a floodplain bench along the left and right banks downstream of Raeford Road will prevent frequent flooding of homes, businesses, and developed properties upstream of Raeford Road. The construction of the floodplain benches along Buckhead Creek downstream of Raeford Road will efficiently convey stormwater within the floodplain of Buckhead Creek, and reduce floodwater elevations on the upstream properties. This alternative does not increase the capacity beneath Raeford Road, and will not have an impact on floodwater elevations downstream of the project area. Alternative 1 meets the requirements of purpose and need, environmental concerns (with mitigation), and economic constraints of the project. This is the Applicant's preferred alternative. This alternative will reduce the recurring local flooding from frequent 2 -year storms by reestablishing a floodplain. Flood reductions during the 25 -year storm will vary between 0.6 feet and 1.0 foot depending on the location. The proposed project area is in a riparian wetland that is a stable, forested community. Much of this community has a shrub layer and many areas are dominated by Chinese privet. The project will require the excavation of 0.97 acres of riparian wetlands. The upland areas surrounding the wetland have been fully developed. The hydrology of the wetland comes from overbank floodwater from Buckhead Creek and subsurface input along the toe slope. The wetland impact is the primary environmental concern regarding this alternative. Excavation will be above the Ordinary High Water Mark of Buckhead Creek, and no stream impacts are associated with this alternative. The floodplain bench along the right bank (looking downstream) was designed to avoid wetland impacts. Work along the stream bank will require immediate stabilization. The excavation area will be stabilized by planting appropriate vegetation. It is anticipated that a wetland will reestablish in the floodplain bench, which is expected to result in a net increase in wetland area. In addition, no other impacts, such as noise, air quality, compatible land use, historic /archaeological resources, or endangered species are anticipated from this project alternative. Raeford Alternative 2: Alternative 2 is similar to Alternative 1 with the exception that the grading of the floodplain bench will avoid wetland impacts to the extent possible. The environmental concern with this project is minimal, provided erosion control measures during construction are properly maintained. However, this alternative does not meet the purpose and need to the extent of Alternative 1. Flood reductions for Alternative 2 during the 25 -year storm will vary between 0.4 feet and 0.5 feet depending on the location, providing approximately 50 to 70 percent of the benefit of Alternative 1. Appendix D contains the HEC -RAS modeling for Alternative 1 and Alternative 2. Raeford Alternative 3: Installing an additional 60 -inch RCP under Raeford Road would result in water surface reductions between 1.8 and 2.1 feet during the 25 -year storm. However, increasing the culvert capacity would increase flows downstream in already floodprone areas. Therefore, additional projects would need to be constructed before installing a culvert under Raeford Road to mitigate the increases in flow and prevent a significant increase in water surface elevation. Additional project constraints for installing a floodplain culvert under Raeford Road must also be addressed prior to proceeding with the project. Raeford Road is a major thoroughfare through the City of Fayetteville, and closing the road or individual lanes would be difficult even at night. Therefore, it is likely that the additional culvert would need to be installed with tunneling techniques. Precise location of all utilities in the Raeford Road corridor would be required prior to installation of the new culvert to avoid potential utility conflicts or disruptions. Significant coordination between NCDOT and the City of Fayetteville will be required for the design and construction of this alternative as Raeford Road is a NCDOT - maintained road. Given all of the constraints with this project, it is anticipated that if it is constructed, the timeframe for implementation would be lengthy. Raeford Alternative 4: The buyout/relocation of affected homes /businesses would remove development from the identified affected areas near Raeford Road. Based on questionnaire complaints and model results, 54 properties would likely need to be bought to remove floodprone houses from the floodplain. Buyout costs based on tax values were estimated to be $14,000,000 for properties and $700,000 for administrative costs. A lost tax base was not estimated. This alternative would require the consent of property owners. The costs to purchase properties would be significant. Identification of all affected properties could be problematic, potentially exposing the City to litigation. This alternative would not adequately solve the flooding problems without major disruption to the existing community, and it is not a preferred alternative. Raeford Alternative 5: This alternative requires the development of detention BMPs up- gradient of the flooding that would be adequate to reduce peak flow and downstream flooding potential. The watersheds contributing to flooding issues along Buckhead Creek are considered at the built -out stage. Very little space is available upstream of the project area to construct a detention facility suitably sized to have a significant impact on reducing water surface elevations and peak flows for the design storm events. The only open space in the watershed upstream of Raeford Road large enough to accommodate a large detention facility is located between the railroad and Raeford Road east of Buckhead Creek. However, this area is approximately 30 feet higher in elevation than the stream. It is estimated that approximately 350,000 cubic yards of fill would need to be removed to construct a 10 -acre detention facility. The estimated cost of the earthwork alone would be approximately $3.5 million, which does not include other project components, such as the land cost. Based on the lack of available space and the high cost to retrofit the area upstream of Raeford Road to a detention facility, Alternative 5 is not considered a cost - effective, feasible alternative for flood reduction in this area. Raeford Alternative 6: The "No Build" Alternative would leave the existing natural environment undisturbed. However, the "No Build" alternative does not fulfill the purpose and need of the City of Fayetteville to reduce flooding risks, and is not consistent with the City's stormwater infrastructure and management policies. This alternative does not reduce flooding or improve water quality within the Buckhead Creek watershed, and it is not a preferred alternative. 0 Table 2.

While Alternative 2 is less expensive and does not have wetland impacts, the flood reduction benefit is not as significant. Given the widespread flooding upstream of Raeford Road, the benefits for the Raeford Road project should be maximized to reduce the flood damages. Maximizing the flood reduction benefits will reduce the frequency and severity of flooding, thereby reducing the overall damages. Alternative 3 provides the greatest benefit to the residents upstream of Raeford Road; however, it will result in increased flows and water surface elevations downstream, where flooding issues already exist. Furthermore, installing a culvert under Raeford Road would require significant coordination due to the traffic volume on Raeford Road and the utilities within the corridor. The other alternatives investigated were either not beneficial to reducing flooding or too costly to consider. While the preferred alternative impacts 0.97 acres of wetland, the impacted wetlands will be regraded to create a floodplain bench that will likely develop back into a wetland in the future since the ground elevation will be lowered. The bench area will be replanted to further increase the potential for wetland functions to be restored. 3.4 Evaluated Alternatives for Coventry Road Coventry Alternative 1 (preferred alternative): Alternative 1 includes the installation of two 8 -foot by 6 -foot floodplain culverts and floodplain benches downstream of Coventry Road along both banks. The proposed Alternative 1 improvements reduce the frequency of severity at Coventry Road and the surrounding properties. Alternative 1 meets the requirements of purpose and need, environmental concerns (with mitigation), and economic constraints of the project. This is the Applicant's preferred alternative. This alternative will reduce the recurring local flooding from frequent storm events by reestablishing a floodplain and increasing the conveyance capacity under Coventry Road. The current level of service at Coventry Road is for the 2 -year storm event, and at some locations along the channel both upstream and downstream of Coventry Road, the 2 -year storm can rise above the bank and into the floodplain. The proposed alternative will provide a 50 -year level of service at Coventry Road with flood reductions during the 25 -year storm varying between 0.9 feet and 3.6 feet, depending on the location. In addition to providing flood protection for properties along Buckhead Creek, the floodplain benching will also lower the tailwater elevation for the Coventry Road culverts, which will provide additional water surface decreases at Coventry Road and upstream of the crossing. The proposed project area is in a riparian wetland that is a stable, forested community. Much of this community has a shrub layer and many areas are dominated by Chinese privet. The project will require the excavation of 0.35 acres of riparian wetlands and 100 linear feet of stream channel. The upland areas surrounding the wetland have been fully developed. The hydrology of the wetland comes from over bank floodwater from Buckhead Creek and subsurface input along the toe slope. The jurisdictional impacts are the primary environmental concern regarding this alternative. Excavation will be above the Ordinary High Water of Buckhead Creek, and no stream impacts to Buckhead Creek associated with the floodplain benching are expected. Approximately 100 feet of stream impacts to an unnamed tributary are required to excavate the floodplain bench. The proposed culverts will be installed one foot higher than the existing culverts to allow the baseflow to continue to flow through the existing culverts. A buried riffle grade control structure will replace the existing rip rap pad. The excavation area will be stabilized by planting appropriate vegetation. It is anticipated that a wetland will reestablish in the floodplain bench, which could potentially result in a net increase in wetland area. In addition, no other impacts, such as noise, air quality, compatible land use, historic /archaeological resources, or endangered species are anticipated from this project alternative. Coventry Alternative 2: Alternative 2 is similar to Alternative 1 with the exception that the grading of the floodplain bench along the right bank would avoid wetland and stream impacts to the extent possible. The environmental concern with this project is minimal, provided erosion control measures during construction are properly maintained. However, this alternative does not meet the purpose and need to the extent of Alternative 1. Flood reductions for Alternative 2 during the 25 -year storm would vary between 0.6 feet and 3.3 feet depending on the location, providing approximately 70 to 90 percent of the benefit of Alternative 1. Appendix D contains the HEC -RAS modeling for Alternative 1 and Alternative 2. Coventry Alternative 3: The buyout/relocation of affected homes /businesses alternative would remove development from the identified affected areas near Coventry Road. Based on the effective 100 -year floodplain, seven homes in the vicinity of Coventry Road are floodprone, and would need to be acquired as part of this alternative. Buyout costs based on tax values were estimated to be $470,000 for properties and $25,000 for administrative costs. A lost tax base was not estimated. This alternative would require the consent of property owners. The costs to purchase properties would be significant. Identification of all affected properties could be problematic, potentially exposing the City to litigation. This alternative would not adequately solve the flooding problems without major disruption to the existing community, and it is not a preferred alternative. Furthermore, the road flooding would not be resolved with this alternative. Coventry Alternative 4: As part of the alternatives analysis, the potential for up- gradient BMP's was investigated. However, due to the high development in the watershed, very few opportunities were available for detention. As noted in Raeford Alternative 5 above, area is available upstream 12 of Raeford Road for detention, but the cost is high, and the benefit would be substantially less at the Coventry Road location since it is further downstream in the watershed. An additional detention site was identified off of Alleghany Road along Buckhead Creek between Raeford Road and Coventry Road. It was determined that a detention pond at this location could reduce the peak flow during the 25 -year storm by between 5 and 10 percent. The cost of the project was expected to be significant due to grading and the required infrastructure to convey runoff to the site. Based on the limited benefit for flood reduction and the high cost, this alternative was not studied further. Coventry Alternative 5: The development of flood control features to the downstream breached Lake Francis would not provide flood control benefits to most of the affected properties. Removing the dam and potentially removing downstream beaver dams would achieve a small measure of flood control by lowering the tailwater along Buckhead Creek; however, the extent of the flood reduction benefits does not extend to the properties impacted by flooding. By removing the dam and potentially removing downstream beaver dams, the water level in the open body of water could be lowered to a level where wetland plantings and a stream channel could be established. Removal of the Lake Francis dam would primarily result in potential mitigative measures, yield only limited flood control benefits, and it is not a preferred alternative. Coventry Alternative 6: The "No Build" Alternative would leave the existing natural environment undisturbed. However, the "No Build" alternative does not fulfill the purpose and need of the City of Fayetteville to reduce flooding risks, and is not consistent with the City's stormwater infrastructure and management policies. This alternative does not reduce flooding or improve water quality within the Buckhead Creek watershed and it is not a preferred alternative. 13 Table 5.

The potential impacts to Buckhead Creek will be minimized by installing the floodplain bench above the OHWM and immediately stabilizing all disturbed areas. The floodplain bench will increase conveyance through the Coventry Road area and reduce flood elevations for the adjoining properties. While Alternative 2 is less expensive and does not have wetland impacts, the flood reduction benefit is not as significant, and, given the widespread flooding at Coventry Road, the benefits for the Coventry Road project should be maximized to reduce the flood damages. Maximizing the flood reduction benefits will reduce the frequency and severity of flooding, thereby reducing the overall damages. The other alternatives investigated were either not beneficial to reducing flooding or too costly to consider. While the preferred alternative does impact 0.35 acres of wetland, the impacted wetlands will be regraded to create a floodplain bench that will likely develop back into a wetland in the future since the ground elevation will be lowered. The bench area will be replanted, further increasing the potential for the wetland to become reestablished. 4.0 ENVIRONMENTAL SETTING 4.1 Physiography, Topography, Geology, and Land Use Fayetteville lies within the Coastal Plain physiographic province of North Carolina. The Coastal Plain is subdivided into the Inner Coastal Plain and the Outer Coastal Plain. The project area is in the Inner Coastal Plain. The topography in the vicinity consists of broad, sloping ridges with steeper side slopes along drainage ways, and is, for the most part, naturally well drained. Elevations on the site range from a low of approximately 150 feet above mean sea level (MSL) along Buckhead Creek below Coventry Road to a high of approximately 180 feet above MSL near Raeford Road. The project area is located in the Cape Fear River basin (HUC 0303000407, NCDWQ Sub basin 03- 06 -15). The project site is underlain by the Cretaceous Black Creek and Middendorf Formations (Horton 1991). The Middendorf formation consists of sand, sandstone, and mudstone that is gray to pale gray with an orange cast, and mottled with clay balls and iron - cemented concretions common. Beds are laterally discontinuous and cross - bedding is common. The Black Creek Formation consists of gray to black clay, and contains thin beds and laminae of fine - grained micaceous sand and thick 15 lenses of cross - bedded sand. There are glauconitic, fossiliferous clayey sand lenses in the upper part (U.S. Geological Survey). The major aquifers of hydrologic importance are the Black Creek and Middendorf Formations. The Black Creek overlies the Middendorf aquifer. The existing land use pattern near the project is almost entirely developed in the upland areas, with development consisting mostly of residential homes, commercial areas along Raeford Road, and a few undeveloped parcels. The floodplains along Buckhead Creek are mostly undeveloped. The total area within sub -basin 03 -06 -15 is 600 square miles; the land area is 595 square miles and the water area is 5 square miles. Land use in sub -basin 03 -04 -02 is: 64.2 percent forest; 1.6 percent surface water; 9.9 percent urban; 14.2 percent cultivated crop; 10 percent pasture /managed herbaceous (NCDWQ 2005). 4.2 Soils Existing soils mapping in the Soil Survey of Cumberland and Hoke Counties, North Carolina (USDA -SCS 1984) shows that the project area contains numerous soil- mapping units. The soil - mapping units located within or immediately adjacent to the site are listed in Table 8. Please refer to Figure 3 for the detailed soils map. Only the Johnston loam is considered hydric by the NRCS. 16 Figure 3.

The project site is located within the USGS 8- digit hydrologic unit 0303000407. The NCDWQ system places the site in sub -basin 03 -06 -15 of the Cape Fear River Basin (NCDWQ 2011). The Stream Index Number (SIN) of Buckhead Creek is 18- 31 -24 -6. Figure 4 depicts the FEMA mapped floodways in the project area. Buckhead Creek flows southward into Little Rockfish Creek and Rockfish Creek before entering the Cape Fear River. Rockfish Creek is one of the major tributaries of the Cape Fear River in this sub - basin. There are five individual NPDES wastewater discharge permits in this subbasin with a combined permitted flow of 53.3 MGD. The largest are Rockfish Creek WWTP (28 MGD) and Cross Creek WWTP (25 MGD) (NCDWQ 20011). 18 Figure 4.

Only the Raeford WWTP discharges into Rockfish Creek in Hoke County. Buckhead Creek, Little Rockfish Creek, and Rockfish Creek are not listed on the 2010 list of 303d impaired waters. Buckhead Creek is assigned a Best Usage Classification of C. Class C waters are freshwater that are protected for aquatic life propagation and survival, fishing, wildlife, secondary recreation, and agriculture. Buckhead Creek flows beneath Raeford Road, through a relatively undeveloped floodplain, and then beneath Coventry Road. It then flows between residential developments to Lake Francis along the eastern edge of an undeveloped floodplain. Lake Francis dam had been breached with a lowered water elevation. Buckhead Creek is classified as C (DWQ water quality classification). Water quality is assessed by NCDWQ through several programs, including benthic macro - invertebrate monitoring, fish community structure, and aquatic toxicity monitoring. There are no NCDWQ sample sites for bioclassification on Buckhead Creek or on Little Rockfish Creek downstream of the project site (NC DWQ 2005). Little Rockfish Creek has had a use support rating of 'Good' since 1993. It was not rated in the most recent monitoring period ending in 2005. NCDWQ continues to monitor Little Rockfish Creek, for changes in the invertebrate population that may be related to land- disturbing activities. Best Management Practices (BMPs) are recommended for the Buckhead Creek watershed. As of 2010, there are no known point- source discharges along Buckhead Creek (NC DWQ 2010). 5.0 BIOLOGICAL RESOURCES 5.1 Plant Communities Distribution and composition of plant communities throughout the project study area reflect landscape -level variations in topography, soils, hydrology, and past and present land use practices. When appropriate, the plant community names have been adopted and modified from the NHP classification system (Schafale and Weakley 1990) and the descriptions written to reflect local variations within the project study area. Three plant communities were identified within the project study area: coastal plain small stream swamp, mixed hardwood /pine forest, and maintained /disturbed lands. Scientific nomenclature typically follows Radford et. al. (1968). Coastal Plain Small Stream Swamp — The coastal plain small stream swamp communities on the project property are located within the active floodplain of Buckhead Creek. These communities flood on an irregular basis, and most plant life is adapted to seasonal flooding and extended periods of soil saturation. The canopy includes swamp tupelo (Nyssa sylvatica), sweetgum (Liquidambar styraciflua), tulip poplar (Liriodendron tulipifera), red maple (Acer rubrum), and bald cypress (Taxodium distichum). Shrubs include American holly (Ilex opaca), large gallberry (Ilex coriacea), ironwood (Carpinus caroliniana), tag alder (Alnus serrulata), southern magnolia (Magnolia grandiflora), and possumhaw viburnum (Viburnum nudum). Chinese privet (Ligustrum sinensis) is common and locally dense. Other vegetation present is giant cane (Arundinaria gigantea), netted chainfern (Woodwardia areolata), roundleaf green briar (Smilax rotundifolia), sawtooth blackberry (Rubus argutus), eastern poison ivy (Toxicodendron radicans), and Japanese 20 honeysuckle (Lonicera japonica). The coastal plain small stream swamp community is mostly jurisdictional wetlands. Mixed Hardwood /Pine Forest — Tree species in this community include loblolly pine (Pinus taeda), red maple, tulip poplar, and sweetgum. Groundcover species consist of roundleaf greenbriar, giant cane, sweet pepperbush (Clethra alnifolia), Chinese privet, and Virginia creeper (Parthenocissus quinquefolia). These areas are non - jurisdictional uplands. Maintained /Disturbed Land — These areas result from previous human disturbances, and include areas subject to periodic mowing and other maintenance activities. The existing road shoulders, utility easements, and mowed areas around businesses and residential properties are included in this habitat type. Species documented in the disturbed /maintained areas include Japanese honeysuckle, eastern poison ivy, sawtooth blackberry, lespedeza (Lespedeza spp.), and broomsedge (Andropogon virginicus). Various managed turf grasses and horticultural plants are also present in this community type. These areas are non - jurisdictional uplands. 5.2 Wildlife The location of the project site is in a generally suburban setting with small commercial businesses and neighborhoods of single - family homes scattered throughout. The area surrounding the project has fragmented habitat, while the project area is a relatively contiguous corridor along the Buckhead Creek drainage. Much of the wildlife occurring in the project study area consists of species that are adapted to fragmented landscapes. Impacts to wildlife will likely be displacement due to habitat loss. Terrestrial Wildlife Common mammals known or expected to occur on -site include: white - tailed deer (Odocoileus virginianus), beaver (Castor Canadensis), eastern fox squirrel (Sciurus niger), raccoon (Procyon lotor), eastern cottontail (Sylvilagus floridanus), and opossum (Didelphis virginiana. Avian species observed or expected to occur on -site include species commonly occurring in forested and disturbed areas of the region. These species include: common crow (Corvus brachyrhynchos), turkey vulture (Cathartes aura), red - shouldered hawk (Buteo lineatus), red - tailed hawk (Buteo jamaicensis), American kestral (Falco sparverius), ruby- throated hummingbird (Archilochus colubris), brown- headed nuthatch (Sitta pusilla), Carolina Wren (Thryothorus ludovicianus), blue jay (Cyanocitta cristata), American robin (Turdus migratorius), northern cardinal ( Cardinalis cardinalis), brown thrasher (Toxostoma rufum), carolina chickadee (Parus carolinensis), and tufted titmouse (Baeolophus bicolor). Reptilian species known or expected to occur on -site include:, green anole (Anolis carolinensis), eastern box turtle (Terrapene carolina), snapping turtle (Chelydra serpentina), cottonmouth (Agkistrodon piscivorus), black rat snake (Elaphe obsoleta), eastern garter snake (Thamnophis sirtalis), northern water snake (Nerodia sipedon), and redbelly water snake (Nerodia erythrogaster). Aquatic Wildlife Aquatic avian species observed or expected to occur on -site include the belted kingfisher (Ceryle alcyon), blue heron (Ardea herodias), wood duck (Aix sponsa), and mallard (Anas platyrhynchos). Amphibian species observed or expected to occur on site include species commonly occurring in small streams, ponds, and wet forests. These species include: southern leopard frog (Rana 21 sphenocephala), Fowler's toad (BUfo woodhousii fowleri), marbled salamander (Ambystoma opacum), two -lined salamander (Eurycea cirrigera), red - spotted newt (Notophthalmus viridescens), southern cricket frog (Acris gryllus), spring pepper (Pseudacris crucifer), southern dusky salamander (Desmognathus auriculatus), and southern leapord frog (Rana sphenocephala). (Martof 1980) 6.0 CULTURAL RESOURCES The term "cultural resources" refers to prehistoric or historic archaeological sites, structures, or artifact deposits over 50 years old. "Significant" cultural resources are those sites that are eligible or potentially eligible for inclusion in the National Register of Historic Places. Evaluations for cultural resources are required whenever a Section 404 permit application is submitted to USACE. Evaluations of site significance are made with reference to the eligibility criteria of the National Register (33 CFR 60) and in consultation with the North Carolina State Historic Preservation Office (SHPO). Beyond the existing culverts, there are no structures, historic or otherwise, to be impacted from these proposed projects. 7.0 JURISDICTIONAL ISSUES The field investigation identified three wetlands and three streams within the project areas (Table 9). The Raeford Road project has two wetlands and one stream. The Coventry Road project has one wetland and two streams. Table 9. Jurisdictional Waters Wetland Acres Site Raeford Road — East 2.12 Raeford Road Raeford Road — West 2.82 Raeford Road Coventry Road 1.93 Coventry Road Stream LF Site Buckhead Creek 1,002 Raeford Road Buckhead Creek 1,541 Coventry Road UT 1 to Buckhead Creek 193 Coventry Road 7.1 Jurisdictional Wetlands Section 404 of the Clean Water Act (CWA) requires regulation of discharges into "waters of the United States." Although the principal administrative agency of the CWA is the Environmental Protection Agency (EPA), the USACE has major responsibility for implementation, permitting, and enforcement of provisions of the Act. The USACE regulatory program is defined in 33 CFR 320- 330. Water bodies such as rivers, lakes and streams are subject to jurisdictional consideration under the Section 404 program and are discussed in Section 7.3. However, by regulation, wetlands are also considered "waters of the United States." Wetlands are defined as: Those areas that are inundated or saturated by groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. 22 Wetlands generally include swamps, marshes, bogs and similar areas. [33 CFR 328.3(b) (1986)] The USACE requires the presence of three parameters (hydrophytic vegetation, hydric soils, and evidence of jurisdictional hydrology) in support of a jurisdictional determination. The delineation was reviewed on 22 July 2011 by Crystal Amschler. USACE data forms and Jurisdictional Determination (Rapanos) forms are provided in Appendix A. Wetland boundaries were delineated using current methodology outlined in the 1987 Army Corps of Engineers Wetland Delineation Manual (DOA 1987) and Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Atlantic and Gulf Coastal Plain Region (Version 2.0) (U.S. Army Corps of Engineers 2010). Soils were characterized and classified using the Field Indicators of Hydric Soils in the United States, Version 7.0 (USDA -NRCS 2010). Wetland boundaries were marked with sequentially numbered wetland survey tape (pink/black striped). Flag locations were surveyed under the direction of a Professional Licensed Surveyor (PLS) with GPS and conventional survey. Figure 5 depicts the National Wetlands Inventory map and Figure 6 depicts the jurisdictional wetlands and surface waters occurring in the project study area at a smaller scale than the maps provided in Appendix A. Both the Raeford Road and Coventry Road properties are traversed by Buckhead Creek where the floodplain is relatively wide. The wetlands are regularly flooded by out -of -bank events. The wetlands are variable, ranging from shallow, depressional areas to extensive backwater wetlands. A typical soil has a sandy or mucky mineral surface texture, and is underlain with silty or clayey horizons. The jurisdictional wetlands within the boundaries can be characterized as riparian wetlands. Riparian areas, including wetlands, are transitional between terrestrial and aquatic ecosystems, and are distinguished by gradients in biophysical conditions, ecological processes, and biota. They are areas through which surface and subsurface hydrology connect water bodies with the adjacent uplands. They include portions of terrestrial ecosystems that influence exchanges of energy and matter with aquatic ecosystems (National Research Council 2002). Riparian areas are adjacent to perennial, intermittent, and ephemeral streams and lakes. Because riparian areas occupy a gradient in the landscape, they can include both wetland and upland habitat. It is this gradient and the diverse biogeochemical processes that occur in riparian areas that make them so important to the overall health of aquatic ecosystems. Riparian areas also serve as a filter between developed uplands and low -lying floodplains and swamps, thus reducing the amount of pollutants and contamination entering surface waters. 23 Figure 5.

(1979). Palustrine systems are defined by Cowardin et al. (1979) as all non -tidal wetlands dominated by trees, shrubs, persistent emergents, emergent mosses or lichens, and all such wetlands that occur in tidal areas where the salinity due to ocean - derived salts is below 0.5 parts per thousand. The,Raeford Road site is shown as palustrine forested, broad - leaved deciduous, semi permanently flooded /saturated (PF01 F), and the Coventry Road site is shown as palustrine forested, broad - leaved deciduous, seasonally flooded, diked /impounded (PFO1 Ch). 7.2 Isolated Wetlands There are no isolated wetlands on the Coventry Road or Raeford Road properties. All wetlands identified are located on the Buckhead Creek floodplain and are subject to overbank flooding. 7.3 Streams On -site stream channels consist of Buckhead Creek, which runs through both sites, and one unnamed tributary to Buckhead Creek, which runs through the west side of the floodplain at the Coventry Site. Other ditches and drainageways were investigated, but lacked consistent seasonal flow or a clearly defined channel. Appendix A contains a Waters of the US plat that clearly identifies the streams. The unnamed tributary to Buckhead Creek is a small channel showing evidence of past excavation along the banks. Buckhead Creek is a large stream system with clearly defined geomorphic features and habitat diversity. A topographic survey was conducted to determine the top of bank locations and elevations of the adjacent floodplain. 8.0 JURISDICTIONAL IMPACTS In accordance with provisions of Section 404 of the CWA (33 U.S.C. 1344), a permit will be required from the USACE for the discharge of dredged or fill material into "Waters of the United States." Section 401 of the CWA (33 U.S.C. 1341) requires each state to certify that state water quality standards will not be violated for activities which: 1) involve issuance of a federal permit or license; or 2) require discharges to "waters of the United States." The use of a Section 404 permit requires the prior issuance of the 401 certification. Therefore, the applicant must also apply to NCDWQ for 401 certification. This process is typically handled as a joint permit application to both the USACE and NCDWQ. Table 10 details the jurisdictional impacts. Table 10. Jurisdictional Impacts Summary Project Site Feature Excavation Fill Total Raeford Road Riparian Wetland (acres) 0.97 None 0.97 Coventry Road Riparian Wetland (acres) 0.34 None 0.34 Coventry Road Stream (linear feet) 100 None 100 The projects are designed to have no impact on Buckhead Creek. All work will be accomplished above the Ordinary High Water Mark (OHWM). 8.1 Wetland Impacts The project will entail unavoidable impacts to riparian wetlands. Riparian wetland impacts will result from construction of the Raeford Road and Coventry Road Stormwater Infrastructure Improvement Projects on the Buckhead Creek floodplain. The types of wetland impacts consist of clearing and excavation. Appendix B provides the detailed construction plans. 26 8.2 Stream Impacts The Coventry Road project will impact 100 linear feet of stream. The stream impacts are to an unnamed tributary and include excavation below the existing bed. The channel will outlet in to a level spreader to provide diffuse flow into the riparian buffer. All work on Buckhead Creek will be above the OHWM, as identified and surveyed. Appendix B provides the detailed construction plans. Due to the excavation within the wetlands adjacent to the channel, more frequent out -of- bank events are expected, reducing the sheer forces on the channel. All disturbed areas adjacent to the channel will be stabilized quickly through erosion matting, temporary seeding, live staking, and container planting. 9.0 MITIGATION Mitigation includes: a) avoidance; b) minimization; and c) compensation for unavoidable impacts. Mitigation of wetland impacts is recommended in accordance with Section 404(b)(1) Guidelines of the CWA (40 CFR 230). Section 404(b)(1) Guidelines stress avoidance and minimization as primary considerations for protection of wetlands. Practicable alternatives analyses must be fully evaluated before compensatory mitigation can be discussed. 9.1 Mitigation Procedure The preferred alternatives include impacts to wetlands and streams. Mitigation of these impacts is the primary environmental concern regarding the project. Prior to compensatory mitigation, impacts must be avoided and minimized. Avoidance — Significant jurisdictional streams and wetland areas are present within the project area. During the planning and design phase of the project, efforts were made to avoid impacts to the greatest extent practicable. It was not be possible to avoid all impacts to jurisdictional areas due to design constraints. Impacts have been avoided where practicable. Certain unavoidable impacts are necessary to fulfill the applicant's purpose and need. Minimization — The Applicant minimized impacts to wetlands in the design phase. The Stormwater Infrastructure Improvement Projects for Raeford Road and Coventry Road must meet NPDES and City of Fayetteville criteria. Minimization efforts include restricting excavation to elevations above the OHWM and placement of additional culverts on the floodplain instead of in the stream channel. Following avoidance and minimization, compensatory mitigation for unavoidable wetlands impacts can be accomplished via several methods, including: • On -Site Mitigation: • Preservation of existing wetlands, • Restoration or enhancement of wetlands, and • Creation of wetlands; • Off -Site Mitigation: • Preservation of existing wetlands, • Restoration or enhancement of wetlands and /or streams in HUC, and 27 • Purchase of credits from approved Mitigation Bank and /or NCEEP in HUC. The potential on -site mitigation is limited to wetland reestablishment and wetland creation along Buckhead Creek. There are currently no available mitigation bank credits available for sale in the project HUC. It is assumed that mitigation could be satisfied through payment of the in -lieu fee to NCEEP. 9.2 Compensatory Mitigation Plan The Applicant is proposing to reestablish wetlands at a lower elevation to the extent of current conditions, and provide created wetlands adjacent to the reestablished wetland. Wetland reestablishment will be at a 1:1 ratio. Temporary loss of function as the new wetland system establishes and the forest matures will be mitigated by the additional created wetlands at a 0.5:1 ratio. Raeford Road Mitigation: • Reestablishment of 0.97 acres of riparian forest wetland within three years, • Creation of 0.49 acres of riparian forest wetland within three years, and • Third -party escrow account valued at 2:1 ratio for 0.97 acres of riparian forest wetland (1.94 WMUs) (exact value determined by price of available credits at time of escrow set- up). Coventry Road Mitigation: • Reestablishment of 0.34 acres of riparian forest wetland within three years, • Creation of 0.20 acres of riparian forest wetland within three years, and • Third -party escrow account valued at 2:1 ratio for 0.34 acres of riparian forest wetland (0.68 WMUs) (exact value determined by price of available credits at time of escrow set- up). The proposed reestablishment and creation of on -site wetlands will be documented with a delineation report provided by the applicant to the USACE and NCDWQ. The delineation will be performed following the third growing season post- construction, and will follow the 1987 Army Corps of Engineers Wetland Delineation Manual (DOA 1987) and Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Atlantic and Gulf Coastal Plain Region (Version 2.0) (U.S. Army Corps of Engineers 2010). If the reestablished wetlands or created wetlands fail to meet jurisdictional criteria, the escrow funds will be used to purchase in -lieu fee or mitigation bank credits to meet the difference. The escrow funds will be released upon confirmation from USACE that all mitigation criteria have been met. 28 9.3 Additional Mitigation Activities Sedimentation Control The Raeford Road and Coventry Road Stormwater Infrastructure Improvement projects will require a sediment control permit from NCDWQ. The Applicant will install and maintain all erosion control measures needed to minimize or prevent sediment from reaching Buckhead Creek to the extent practicable. Additionally, the proposed stockpile area for excavated material is located on city property. Strict erosion control measures will be incorporated at the stockpile area to prevent sediment from entering wetland and stream systems. Erosion control measures will include: double rows of silt fencing, sediment pond with baffles and skimmer, rack and filter fabric inlet protection, gravel construction entrances, rock check dams, temporary seeding, and permanent seeding. Proper controls and mitigation measures will avoid impacts to water quality during construction. During construction, water pollution control will take place in accordance with FAA AC 150/5370 -10A, North Carolina statues, local requirements, and any requirements associated with construction in the Cape Fear River Basin. The Engineer will be responsible for assuring compliance to the extent that construction practices, construction operations, and construction work is involved. Temporary control measures will be developed and shown on the construction plans. Control measures will be implemented as depicted, or modified as site conditions dictate, as ordered by the Engineer during the life of the construction contract to control water pollution, soil erosion, and siltation. As long as proper erosion control measures are designed, installed, and maintained, no long -term adverse effects should be present as a result of this project. 10.0 PROTECTED SPECIES The Endangered Species Act requires each federal agency to ensure that any action by that agency is not likely to jeopardize the continued existence of any threatened or endangered species, or destroy, or adversely modify critical habitat for those species. 10.1 Federal Threatened and Endangered Species Species with the federal classification of Endangered (E), Threatened (T), or officially Proposed (P) for such listing, receive protection under the Endangered Species Act of 1973 (16 US 1531 et seq.) as amended. The United States Fish and Wildlife Service list seven federally protected species for Cumberland as of the September 22, 2009 listing (Table 11). Records held by the North Carolina Natural Heritage Program (NHP) were reviewed by WK Dickson in May 2008 to determine if any federally protected species have been documented from the project study area or the surrounding vicinity. 29 Table 11. Federal Protected Species for Cumberland County, North Carolina Common Name Scientific Name Federal Habitat Biological Status Present Conclusion American alligator Alligator mississippiensis T (S /A) No No Effect Red - cockaded Picoides borealis E No No Effect woodpecker Saint Francis' satyr Neonympha mitchellii francisci E No No Effect butterfly American chaffseed Schwalbea americana E No No Effect Michaux's sumac Rhus michauxii E No No Effect May Effect, Pondberry Lindera melissifolia E Yes Not Likely to Affect Rough - leaved Lysimachia asperulaefolia E No No Effect loosestrife USFWS September 22, 2009 Investigations were completed in 2010 at the sites of the proposed stormwater infrastructure improvement projects to determine if any endangered or threatened species or critical habitat were present and likely to be affected by the construction. As a result of the investigations, the only protected species that has a potential for occurring in the area is the pondberry ( Lindera melissifolia). This plant has an historic occurrence approximately 2.5 miles from the project area. The existing conditions are less than ideal; the habitat is degraded, has a dense understory of privet, and a history of disturbance. No occurrences were identified during field surveys and wetland delineation. Federal and State guidelines will be followed to prevent any potential harmful effects of erosion and sedimentation during construction. 10.2 Biological Conclusions AMERICAN ALLIGATOR The American alligator is a large, semi - aquatic, armored reptile that is related to crocodiles. It's body alone ranges from 6 to 14 feet long. Almost black in color, it has prominent eyes and nostrils with coarse scales over the entire body. It has a large, long head with visible upper teeth along the edge of the jaws. Its front feet have five toes, while rear feet have four toes that are webbed. To prevent trafficking of look -alike reptiles, the U.S. Fish and Wildlife Service classifies the alligator as "threatened due to similarity of appearance" since it resembles the American crocodile. The American alligator is no longer biologically endangered or threatened and, therefore, will not be affected by the projects. RED - COCKADED WOODPECKER The red - cockaded woodpecker (RCW) is 7 to 8.5 inches long, has a black head, prominent white cheek patch, and a black- and -white barred back. Males often have red markings (cockades) behind the eye, but the cockades may be absent or difficult to see (Potter et al. 1980). Primary habitat consists of mature to over - mature southern pine forests dominated by loblolly, long -leaf (P. 30 palustris), slash (P. elliotii), and pond (P. serotina) pines (Henry 1989). Primary nest sites for RCWs include open pine stands greater than 60 years of age with little or no mid -story development. Nest cavity trees tend to occur in clusters, which are referred to as colonies (USFWS 2003). Optimal foraging habitat is comprised of open pine stands with large pines 60 years old or greater, low densities of small or medium pines, sparse or no hardwood midstory, and various species of bunchgrass for groundcover (USFWS 2003). However, open pine or pine /mixed hardwood stands over 30 years of age are considered potential foraging habitat (Henry 1989). Pine flatwoods or pine-dominated savannas, which have been maintained by frequent natural fires, serve as ideal nesting and foraging sites for this woodpecker. Development of a thick understory may result in abandonment of cavity trees. The woodpecker drills holes into the bark around the cavity entrance, resulting in a shiny, resinous buildup around the entrance that allows for easy detection of active nest trees (Henry 1989). Buckhead Creek and the surrounding area do not have suitable habitat for the red - cockaded woodpecker. A review of NHP records did not reveal an element occurrence within two. miles of the project. As a result, no effect to red - cockaded woodpecker is anticipated from the proposed project. BIOLOGICAL CONCLUSION: NO EFFECT SAINT FRANCIS' SATYR BUTTERFLY The Saint Francis' Satyr is a small, dark brown butterfly with conspicuous "eye spots" on the lower surfaces of the wings. The wingspan for the species ranges from 34 to 44 millimeters. The eyespots are usually round to slightly oval on the forewing and on the hindwing. The spots are accented by orange bands (Black, S. H., and D. M. Vaughan. 2005). The annual life cycle of Saint Francis' Satyr typically has two adult generations per year. Population presently occurs in low densities, probably only consisting of about 100 adults a year or less. It is known only from a few sedge wetlands in close proximity. Its habitat is wet meadows dominated by sedges that were likely created by fire or beaver activity, although now mainly maintained by human activity. Habitat is successional or disclimax with both beaver and fires apparently critical factors in maintaining it. Adult food habits are not known, but it probably feeds on Carex spp. or small PaniCLIM spp. Buckhead Creek and the surrounding area do not have suitable habitat for the Saint Francis' Satyr. A review of NHP records did not reveal an element occurrence within two miles of the project. As a result, no effect to Saint Francis' Satyr is anticipated from the proposed project. BIOLOGICAL CONCLUSION: NO EFFECT AMERICAN CHAFFSEED American chaffseed is a perennial herb with mostly unbranched stems, usually 1 to 2 feet tall. Leaves are largest at the base of the plant, and gradually diminish in size towards the top of the stem. The two - lipped flowers are yellow, suffused with purple. This species is parasitic on the roots of a wide variety of woody and herbaceous plants. It is in bloom from April through June in the South, and from June to late July in the North. American chaffseed is primarily a Coastal Plain species of the Atlantic and Gulf coasts, with historic locations ranging from Massachusetts to Florida to east Texas. It is usually found in acidic, sandy, or peaty soils in open pine flatwoods, pitch pine lowland forests, seepage bogs, palustrine pine 31 savannahs, or other grass- and sedge- dominated plant communities. It frequently grows in ecotonal areas between peaty wetlands and xeric sandy soils. In these situations, individuals sometimes extend well into the drier communities, but seldom into the areas that support species characteristic of wetter soils. Surrounding plant communities are typically species -rich. Buckhead Creek and the surrounding area do not have suitable habitat for the American chaffseed. A review of NHP records did not reveal an element occurrence within two miles of the project. As a result, no effect to American chaffseed is anticipated from the proposed project. BIOLOGICAL CONCLUSION: NO EFFECT MICHAUX'S SUMAC Michaux's sumac is a rhizomatous, densely hairy shrub with erect stems from 1 to 3 feet in height. The compound leaves contain evenly serrated, oblong to lanceolate, acuminate leaflets. Most plants are unisexual; however, more recent observations have revealed plants with both male and female flowers on one plant. The flowers are small, borne in a terminal, erect, dense cluster, and colored greenish yellow to white. Flowering usually occurs from June to July; the fruit, a red drupe, is produced through the months of August to October. Michaux's sumac grows in sandy or rocky open woods in association with basic soils. This plant survives best in areas where some form of disturbance has provided an open area. At least twelve of the plant's populations in North Carolina are on highway rights -of -way, roadsides, or on the edges of artificially maintained clearings. Two other populations are in areas with periodic fires, and two populations exist on sites undergoing natural succession. One population is situated in a natural opening on the rim of a Carolina bay. Buckhead Creek and the adjoining floodplain do not have suitable habitat for the Michaux's sumac. The surrounding area consists mostly of developed lands and does not contain suitable habitat. Impacts to the surrounding uplands will be limited. A review of NHP records did not reveal an element occurrence within two miles of the project. As a result, no effect to Michaux's sumac is anticipated from the proposed project. BIOLOGICAL CONCLUSION: NO EFFECT PONDBERRY This deciduous shrub grows to approximately 6 feet tall, and spreads vegetatively by stolons. Pale yellow flowers appear in the spring before the leaves. The bright red, one - half -inch long, oval - shaped fruits mature in the fall. Pondberry is distinguished from the two other North American members of the genus (Lindera benzoin and Lindera subcoriacea) by its drooping, thin, membranaceous, and ovately- to elliptically- shaped leaves that have a strong, sassafras -like odor when crushed. In North Carolina, one population exists in Bladen County. Pondberry, for the most part, is associated with wetland habitats, such as bottomland and hardwoods in the interior areas, and the margins of sinks, ponds and other depressions in the more coastal sites. The plants generally grow in shaded areas, but may be found in full sun. Pondberry occurs in soil with sandy sediments and high peat content in the subsurface having a high water table. A survey for pondberry was performed by WK Dickson in April 2011. No individuals were observed in the area proposed for the Raeford Road and Coventry Road Stormwater Infrastructure Improvement Projects. Specifically, the project areas were investigated and no suitable habitat was found. 32 BIOLOGICAL CONCLUSION: NO EFFECT ROUGH - LEAVED LOOSESTRIFE Rough - leaved loosestrife is a perennial herb in the Primrose Family (Primulaceae) that grows 1 to 2 feet tall. Whorls of three to four entire, triangular- shaped leaves encircle the stem. The leaves are widest at the base (0.3 to 0.75 inches wide) and have three prominent veins. Contrary to the common name, the leaf surfaces are smooth to the touch. The yellow flowers are 0.6 inches across with yellow- orange anthers and occur on terminal racemes that are 1 to 4 inches long. Flowering occurs from mid -May through June, with fruits (capsules) present from July through October. Stipitate glands are usually present on most parts of the plant. This species generally occurs in the ecotones or edges between longleaf pine uplands and pond pine pocosins on moist to seasonally saturated sands and on shallow organic soils overlaying sand. Rough - leaved loosestrife has also been found on deep peat in the low shrub community of large Carolina bays. The grass -shrub ecotone, where rough - leaved loosestrife is found, is fire - maintained, as are the adjacent plant communities (longleaf pine - scrub oak, savanna, flatwoods, and pocosins). Suppression of naturally occurring fire in these ecotones results in shrubs increasing in density and height, and expanding to eliminate the open edges required by this plant. A survey for rough - leaved loosestrife was performed by WK Dickson in 2011. No individuals were observed in the area proposed for the Raeford Road and Coventry Road Stormwater Infrastructure Improvement Projects. Specifically, the project areas were investigated and no suitable habitat was found. BIOLOGICAL CONCLUSION: NO EFFECT 10.3 Federal Species of Concern The USFWS list also includes a category of species designated as "Federal Species of Concern" (FSC). The FSC designation provides no federal protection under the ESA for the species listed. However, these species are listed because they may attain federally protected status in the future. The presence of potential habitat within the project study area has been evaluated for the FSC species listed for Cumberland County (Table 12). No surveys for FSC species have been conducted. In the course of other field investigations, no FSC species have been observed. 33 Table 12.

Due to the nature of the project, excavation will remove topsoil and expose subsurface soils along the floodplain. Stockpiled topsoil will be distributed across the excavated floodplain to provide an appropriate soil medium for wetland vegetation and a seed bank. Currents, Circulation, or Drainage Patterns — Wetland impacts are proposed. However, proposed changes to the overall drainage of the site are anticipated to allow out -of -bank events to occur more often, and will retain floodwaters for short periods, allowing the sites to treat both quantity and quality of run -off. Suspended Particulates and Turbidity — The Erosion and Sedimentation Control Plan will be strictly enforced to maintain state water quality standards during construction. Water Quality — Overall water quality on the site is not expected to change significantly as a result of the new construction. The project will treat both quantity and quality of run -off. Flood Control Functions — Alterations to the site will increase flood conveyance functions. Storm, Wave and Erosion Buffers — Not Applicable Aquifer Recharge — The project will not have an effect on aquifer recharge. Basef low - The project wi I I not have an effect on basef low. 11.2 Biological Characteristics and Anticipated Changes Special Aquatic Sites — Certain unavoidable impacts to wetlands and streams will result from this project; however, impacts have been minimized as much as practicable. Habitat for Fish and Other Aquatic Organisms — The streams are not expected to be directly impacted. Initially, the mature forest shading the streams will be removed. Stream stabilization with matting and black willow live stakes along the stream banks will rapidly provide shade for the stream. No significant habitat degradation is anticipated in the long -term as a result of the project. Wildlife Habitat - No significant habitat degradation is anticipated as a result of the project. Forested wetland habitat will be replanted in trees after the site is graded and the stockpiled topsoil is redistributed across the site. Appropriate wetland tree species will be planted across the site. Initially, the site will function as an open shrub /herbaceous wetland habitat until the trees mature. Endangered or Threatened Species — No impacts to federally protected species are anticipated from the proposed project. 35 11.3 Human Use Characteristics and Impacts Existing and Potential Water Supplies — The project will have no effect on existing or potential water supplies. Recreational or Commercial Fisheries — No effect. Other Water Related Recreation — No effect. Aesthetics of Aquatic Ecosystem — The Buckhead Creek floodplain in the vicinity of the Stormwater Infrastructure Improvement project is currently a natural forested bottomland hardwood forest. The proposed community will be a minimally maintained open shrub /herbaceous wetland habitat in the short -term. The long -term outlook is to restore the forested floodplain community. Parks, National and Historic Properties, etc. — No effect. Traffic /Transportation Patterns — No effect. Energy Consumption /Generation — No effect. Navigation — No effect. Safety — No effect. Air Quality — No effect. Noise — No effect. Historic Properties — No effect. Land Use Classification — No effect. Economics — The project will reduce or eliminate frequent flooding of homes and business in the Buckhead Creek watershed near these projects. Property Values— Unknown. Regional Growth — The project is not intended as a driver of regional growth. Tax Revenues — No effect. Employment — No effect. Public Facilities — Not applicable. Business Activity — No effect. Prime and Unique Farmland — No effect. 36 Food and Fiber Production — No effect. Water Quantity — The project will increase flood conveyance through the Buckhead Creek watershed. Mineral Needs — No effect. Consideration of Private Property — Will likely improve conditions for some properties by reducing the threat of flooding. Community Cohesion — No effect. Community Growth and Development — No effect. Relocations — None are anticipated as result of this project. Recreation — Not applicable. 11.4 Secondary and Cumulative Impacts No significant secondary and cumulative impact possibilities associated with this project have been identified. The Raeford Road and Coventry Road Stormwater Infrastructure Improvement Projects are intended to facilitate existing economic development and prevent flooding events of existing development. The project is not intended to be a driver of new development. Downstream water quality is not expected to be negatively impacted due to strict sediment and erosion control measures and post - construction stabilization that will treat water quality as well as control water quantity. 12.0 CONCLUSION The Raeford Road and Coventry Road Stormwater Infrastructure Improvement Projects have been designed to minimize wetland and stream impacts while still satisfying the applicant's purpose and need. There will be 0.97 acres of wetland impacts for Raeford Road, and 0.35 acres of wetland impacts for Coventry Road. No stream impacts are planned. Compensatory mitigation for wetland impacts will be provided through the purchase of credits from approved mitigation banks and /or NCEEP. It is the team's desire to meet or exceed all state and federal regulatory requirements in order to construct an environmentally responsible airport expansion. 37 13.0 REFERENCES Black, S. H., and D.

The JD Request covers four separate project sites within the Buckhead Creek watershed. The sites are composed of privately owned parcels and city owned parcels (see attachment). The projects are being undertaken to upgrade existing stormwater structures and reduce flooding impacts to developed properties along Buckhead Creek. These stormwater projects are in the design phase and will ultimately require 404/401 permitting due to unavoidable impacts to streams and wetlands. The attached Preliminary JD Request package includes the preliminary JD Request form, site description, supporting figures, stream data forms, and wetland data forms, Jurisdictional Determination Forms (Rapanos) and property owner information. The supporting Figures include the following: location map, USGS map, NRCS soil map, and aerial photography maps showing streams and wetlands. 720 Corporate Center Drive Raleigh, NC 27607 Tel. 919.782.0495 Fax 919.782.9672 www.wkdickson.com Transportation • Water Resources • Urban Development • Geomatics When you have had an opportunity to review the material, please call me to schedule a site visit if necessary.

Ceonl h(, Buckhead Creek Watershed Stormwater Infrastructure Improvement Project Stream and Wetland Delineation Technical Memorandum Project Information Within the Buckhead Creek watershed, four areas were identified for stormwater infrastructure improvement and were assessed for streams and wetlands (Figure 1). The study area consisted of Coventry Road, Devonshire Drive, Raeford Road, and Buckhead Kingsford. • Coventry Road - This area includes the floodplain along Buckhead Creek at Coventry Road, between Devonshire Drive and Glenwick Drive. • Montclair Subdivision - This area includes uplands and a stream channel along the western edge of Buckhead Creek north of Raeford Road • Raeford Road - This area includes the floodplain along the left bank of Buckhead Creek downstream of Raeford Road. • Buckhead Kingsford is along Murray Hill Road, Levenhall Drive, and Ferncreek Drive. The study area is almost entirely developed in the upland areas with development consisting of mostly residential homes, commercial areas along Raeford Road and a few undeveloped parcels. The floodplains are mostly undeveloped. The upland areas have relatively good infiltration and ditches are usually shallow with roadside ditches a common landscape features. The topography is uniformly broad gently sloping ridges with steeper side slopes along drainage ways. The study area is located in the Cape Fear River basin (HUC 0303000407, DWQ Sub basin 03- 06 -15). The USGS quadrangle (Fayetteville) indicates Buckhead Creek as a large second order stream originating north of the study area near Cross Creek Mall and flowing to the south (Figure 2). Except for Buckhead Creek, no streams or wetland areas are shown on the USGS quadrangle or soil survey (Figure 3). A combination of in -house research and field investigations were performed to determine likely wetland locations, delineate wetland boundaries, and make general habitat observations. Wetland and Stream Delineation The field investigation identified four streams within the project areas (Table 1). In addition to the presence of Buckhead Creek within the Coventry Road and Raeford Road Sites, three small, unnamed tributaries to Buckhead Creek were identified (Figure 4, Figure 5, Figure 6, and Figure 7). A number of excavated ditches were investigated but were found to not be jurisdictional. The Ordinary High Water Mark was located in the field for the streams and surveyed to define the limits of jurisdiction. The field investigation identified four wetlands within the project areas (Table 1). Two wetlands abutting Buckhead Creek were identified at Raeford Road, one to each side of the channel, one wetland abutting Buckhead Creek was identified at Coventry Road to the west of Buckhead Creek, and one wetland is located abutting an unnamed tributary to Buckhead Creek at the Montclair Site. The Montclair wetland borders the project limits, with limited area within of the project study area.

Through these project areas, Buckhead Creek ranges from 10 to 30 feet in width with a 2 to 6 feet bank height. The substrate is primarily sand and gravel. Buckhead Creek is a second order perennial stream that flows south to Rockfish Creek. The water shed is highly urbanized and the streams in this area are subject to rapid rise of stormwater that caused flooding in many of the low -lying residential homes and businesses. The floodplain along Buckhead Creek is variable and ranges up to more than 600 feet wide. A number of wetlands are located along its length. The channel is somewhat incised, but mostly stable with forested vegetation along much of its length. The channel has a substrate of sand and gravel. Vegetation along the channel consists of hardwood trees and shrubs and includes swamp tupelo (Nyssa biflora), red maple (Acer rubrum), Chinese privet (Ligustrum sinense), and possumhaw viburnum (Viburnum nudum). Other vegetation present consists of roundleaf green briar (Smilax rotundifolia), sawtooth blackberry (Rubus argutus), eastern poison ivy (Toxicodendron radicans), and Japanese honeysuckle (Lonicera japonica). Unnamed Tributary 1 to Buckhead Creek (Coventry Road) This channel originates near Coventry Road and Devonshire Drive and flows east across the floodplain through wetlands into Buckhead Creek (Figure 4). This is a small, first order channelized stream. It has been straightened and dredged. Vegetation is the same as found along Buckhead Creek. 720 Corporate Center Drive Raleigh, NC 27607 Tel. 919.782.0495 Fax 919.782.9672 www.wkdickson.com Transportation • Water Resources • Urban Development • Geomatics Unnamed Tributary 2 to Buckhead Creek (Montclair) This channelized stream originates at a culvert draining the Montclair neighborhood (Figure 6). The stream has been channelized and straightened. It has incised stable banks with maintained vegetation within. The channel flows into the forested floodplain of Buckhead Creek before emptying into Buckhead Creek. Riprap is present at the culverts and along the banks. The channel is a sand bed. Within the maintained portions, vegetation is mostly shrubs with a few scattered trees, including American black elderberry (Sambucus nigra), broadleaf cattail (Typha latifolia), arrowleaf tearthumb (Polygonum sagittatum), red maple, swamp tupelo (Nyssa biflora), and American pokeweed (Phytolacca americana) in a narrow strip along the channel banks. Beyond the narrow woody buffer are maintained grasses beyond. The forested buffer includes red maple, swamp tupelo, and Chinese pr ivet, Unnamed Tributary 3 to Buckhead Creek (Buckhead Kingsford) This stream has been channelized along lot boundaries and along a railroad bed (Figure 7). The area is highly disturbed with areas with unstable banks. The water is stagnant with a very low flow. It has a sandy substrate and shallow benches in the channel were observed. The natural vegetation has been highly disturbed and consists of elderberry, red maple, smallspike false nettle (Boehmeria cylindrical), Virginia creeper (Parthenocissus quinquefolia), and Japanese honeysuckle. Broadleaf cattail and submerged aquatic vegetation is present in the shallow waters. WETLANDS Coventry Road Wetland This wetland extends along the floodplain east of Buckhead Creek, beginning approximately 250 feet downstream of Coventry Road culvert. This wetland varies in width from approximately 30 feet to 140 feet, extending from the toe of slope to a narrow berm along the channel. Soils are dark mucky mineral surface underlain by dark sandy textured subsoil to 7 feet. Hydrology is from flooding, groundwater discharge, and extended surface storage. Vegetation in the wetlands consists of hardwood tree canopy with dense to open understory. The canopy includes swamp tupelo, sweetgum (Liquidambar styraciflua), tulip poplar (Liriodendron tulipifera), red maple, bald cypress (Taxodium distichum), and slippery elm (Ulmus rubra). Shrubs include American holly (Ilex opaca) Chinese privet, southern magnolia (Magnolia grandiflora), and possumhaw viburnum. Other vegetation present is giant cane (Arundinaria gigantea) netted chainfern (Woodwardia areolata), roundleaf green briar, sawtooth blackberry, eastern poison ivy, and Japanese honeysuckle. Raeford Road Wetland This wetland extends to both sides of Buckhead Creek. The wetland to the east begins approximately 100 feet downstream of Raeford Road culvert. This wetland varies in width from approximately 40 feet to 350 feet, extending from the toe of slope to the top of bank along the channel. The wetland to the west begins approximately 250 dowstream of the Raeford Road Culvert. This wetland varies in width 720 Corporate Center Drive Raleigh, NC 27607 Tel. 919.782.0495 Fax 919.782.9672 www.wkdickson.com Transportation • Water Resources • Urban Development • Geomatics from approximately 100 feet to 350 feet, extending from the toe of slope to the top of bank along the channel. Soils across these wetlands are variable, but typically dark and sandy textured to 7 feet. Hydrology is from flooding, groundwater discharge, and extended surface storage. Vegetation in the wetlands consists of hardwood tree canopy with dense to open understory. The canopy includes swamp tupelo, sweetgum, tulip poplar, red maple, bald cypress, and slippery elm. Shrubs include American holly (Ilex opaca), large gallberry (Ilex coriacea), elderberry, Chinese privet, and possumhaw viburnum. Other vegetation present is American black elderberry giant cane, roundleaf green briar, sawtooth blackberry, eastern poison ivy, and Japanese honeysuckle. Montclair — Wetland A small area of disturbed wetland is located along the backwater of Buckhead Creek upstream of Raeford Road. This wetland extends outside of the project survey area. It is associated with a small, unnamed tributary to Buckhead Creek having its watershed in the Montclair neighborhood. This wetland has loamy sand and sandy loam textured soil that is saturated much of the year. Evidence of beaver was observed. Typical vegetation includes red maple, Chinese privet, roundleaf green briar, and Japanese honeysuckle. Other Potential Waters of the US Other potential waters of the US were investigated in the study area. No other waters of the US were identified. The roadside ditches and most drainage ditches lacked hydric soil and /or hydrology indicators. Several undeveloped lots were investigated but all lacked hydric soils and /or hydrology indicators. No streams or wetlands were identified in the Raeford Road - Faison project area. SUMMARY OF FINDINGS Jurisdictional streams and wetlands were identified and delineated in the four project areas. Four streams were delineated, including Buckhead Creek, three unnamed tributaries to Buckhead Creek. Buckhead Creek flows through both the Coventry Road and Raeford Road project areas. Extensive forested wetland areas were identifies at the Coventry Road and Raeford Road projects. A small wetland area was found within the Montclair site. Representative photographs, field notes, data forms, and field maps are on file. All delineation boundaries and jurisdictional status determinations are preliminary pending USACE verification. 720 Corporate Center Drive Raleigh, NC 27607 Tel. 919.782.0495 Fax 919.782.9672 www.wkdickson.com Transportation • Water Resources • Urban Development • Geomatics U Nix C9rrrpgr0,,, r Jl Fort Bra lb c Pa{ 1404 bl 87 24 fiat � # � 87 59 --�87 77— - – w � II � G y I� 01961rr.t#aL8 } er4, °�r rur SR 316 n { ' '4 pawstt4�444 Dr HVir:JrEk b rRr�f'� ' 11,01, a k r �' 7 Buckhead Kingsford Project l's Louise Montclair Project, $ UlfoTd Rd 401 Bu 8f 5 Y a Raeford Rd Project o 7 = Ir 01 Rd tai$ 4 x pig° Spruce fi # Rd °harry dap eConter Dr Df " # e"' 'x1 i endhuret OAL gve *C(a Dr Y e+ }hRirU�� 4 d 7 of 05's Ohm # OT Or + ry )NO0610r U 0�, W V' k RQd 01 ee it y D sum s 46 `#t 9 10 R omnadi q Coventry Project 11 * .g A� �f5` Inu 8d�rrt b lenr`d�g�di r Cdr 8F ° bar RV 6** Or c % a t,c Ave * 11 buaiaridge, o At 1kd a ri r at $ ti I-ir C Creek C +r U �1 x l} ve 7 ���yTrM1� 14 1<TM r T�dTt Dosni+��4 SO 14 TrelK Or asce �(,lrT� a o x 1344 �0 •C f q f Cuinbarinnd O Avonctoft Or Figure 1 Buckhead Creek Watershed N Legend PSW K WDICKSON Stormwater Infrastructure Improvement Vicinity Map * Project Sites �amm�r uy inrrasr ��r� a nor s��fa is Miles 0 0.25 0.5 1 Buckhead Creek 1 in = 0.5 miles r Ai F •T '' ' Cliffdale Rd •" � �` -r - "�i �"�� r}r 5• irk � ` � '�- f ' y ' + °{ 'a r. `:; ° t. � _ ;f�- - -�•�, sue_ _.� `I E wa � t 9 er Dr _ R 401 �� ;�- - e. � 2- � � :�� h��ti~ F \ �� �• Y .� N 6 Buckhead Kingsford Project + Montclair Project y i 401 s � EE {efor I Ra d•Rd* e f� , f _ Raeford Rd Project w A•{' .�o';: - • � iris � - � � � I� • ', < � •••]� 4r '%A - IWa_tauga R � ,•ut Dr•- o • ° - � - � y • �F{ �'* ''�.. 12, Ca Ty' al + _ ��„•F <y � a� ;Redwood �w '�" i I Coventry Project o0 • + —..y11 n� F 3 � r � 59 o '�r.. ,co - *•'} ., r� x.. - „w, "` s C �b . � ,�� f x,.11 F��I�r� �.

Limits (boundaries) of jurisdiction based on: Elevation of established OHWM (if known): 2. Non - regulated waters /wetlands (check if applicable):3 Potentially jurisdictional waters and /or wetlands were assessed within the review area and determined to be not jurisdictional. Explain: ' Boxes checked below shall be supported by completing the appropriate sections in Section III below. 2 For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year -round or has continuous flow at least "seasonally" (e.g., typically 3 months). s Supporting documentation is presented in Section IILF. SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section IILA.1 and Section IILD.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections IILA.1 and 2 and Section IILD.1.; otherwise, see Section IILB below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent': B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non - navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year -round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year -round (perennial) flow, skip to Section IILD.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section IILD.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody4 is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section IILB.1 for the tributary, Section IILB.2 for any onsite wetlands, and Section IILB.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section IILC below. 1. Characteristics of non -TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: Pick Li Drainage area: Pick Li Js Average annual rainfall: inches Average annual snowfall: inches (ii) Physical Characteristics: (a) Relationship with TNW: ❑ Tributary flows directly into TNW. ❑ Tributary flows through � tributaries before entering TNW. Project waters are Mick List river miles from TNW. Project waters are Pick List river miles from RPW. Project waters are Pick List aerial (straight) miles from TNW. Project waters are _Pick List aerial (straight) miles from RPW. Project waters cross or serve as state boundaries. Explain: Identify flow route to TNW5: Tributary stream order, if known: 4 Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and West. 5 Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW.

(iii) Chemical Characteristics: Characterize tributary (e.g., water color is clear, discolored, oily film; water quality; general watershed characteristics, etc.). Explain: Identify specific pollutants, if known: 6A natural or man -made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break. 7Ibid.

SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: 1.

Non - regulated waters /wetlands (check if applicable):3 Potentially jurisdictional waters and /or wetlands were assessed within the review area and determined to be not jurisdictional. Explain: ' Boxes checked below shall be supported by completing the appropriate sections in Section III below. 2 For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year -round or has continuous flow at least "seasonally" (e.g., typically 3 months). 3 Supporting documentation is presented in Section IILF. SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section IILA.1 and Section IILD.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections IILA.1 and 2 and Section IILD.1.; otherwise, see Section IILB below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent': B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non - navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year -round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year -round (perennial) flow, skip to Section IILD.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section IILD.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody4 is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section IILB.1 for the tributary, Section IILB.2 for any onsite wetlands, and Section IILB.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section IILC below. 1. Characteristics of non -TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: 14.95square miles Drainage area: 0.034 JLquare mil Average annual rainfall: 46.94 inches Average annual snowfall: 1.4 inches (ii) Physical Characteristics: (a) Relationship with TNW: ❑ Tributary flows directly into TNW. ❑ Tributary flows through' tributaries before entering TNW.

Project waters are I (or less) aerial (straight) miles from RPW. Project waters cross or serve as state boundaries. Explain: Identify flow route to TNWs: The project waters flow southwest into Buckhead Creek. Buckhead Creek flows south into Rockfish Creek which flows directly into the Cape Fear River. 4 Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and West. 5 Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW.

Explain: The water appearance for this tributary is clear. Identify specific pollutants, if known: 6A natural or man -made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break. 7Ibid.

Explain: ' Boxes checked below shall be supported by completing the appropriate sections in Section III below. 2 For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year -round or has continuous flow at least "seasonally" (e.g., typically 3 months). s Supporting documentation is presented in Section IILF. SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section IILA.1 and Section IILD.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections IILA.1 and 2 and Section IILD.1.; otherwise, see Section IILB below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent': B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non - navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year -round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year -round (perennial) flow, skip to Section IILD.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section IILD.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody4 is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section IILB.1 for the tributary, Section IILB.2 for any onsite wetlands, and Section IILB.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section IILC below. 1. Characteristics of non -TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: 14.95 square mile Drainage area: 0.037 asquare mile Average annual rainfall: 46.94 inches Average annual snowfall: 1.4 inches (ii) Physical Characteristics: (a) Relationship with TNW: ❑ Tributary flows directly into TNW. ® Tributary flows through' tributaries before entering TNW.

Explain: Identify flow route to TNWs: The project waters flow east into Buckhead Creek. Buckhead Creek flows south into Rockfish Creek which flows directly into the Cape Fear River. 4 Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and West. 5 Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW.

Explain: The water color is slightly turbid with an oily film. Identify specific pollutants, if known: 6A natural or man -made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break. 7Ibid.

SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: 1.

CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non - navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year -round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year -round (perennial) flow, skip to Section IILD.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section IILD.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody4 is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW.

Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: 1. Significant nexus findings for non -RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section ITI.D: 2. Significant nexus findings for non -RPW and its adjacent wetlands, where the non -RPW flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to Section IILD: 3. Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to Section IILD: D. DETERMINATIONS OF JURISDICTIONAL FINDINGS. THE SUBJECT WATERS /WETLANDS ARE (CHECK ALL THAT APPLY): 1. TNWs and Adjacent Wetlands. Check all that apply and provide size estimates in review area: TNWs: linear feet width (ft), Or, acres. Wetlands adjacent to TNWs: acres. 2. RPWs that flow directly or indirectly into TNWs. Tributaries of TNWs where tributaries typically flow year -round are jurisdictional. Provide data and rationale indicating that tributary is perennial: Buckhead Creek is a Second Ordre stream. Tributaries of TNW where tributaries have continuous flow "seasonally" (e.g., typically three months each year) are jurisdictional. Data supporting this conclusion is provided at Section ITI.B. Provide rationale indicating that tributary flows seasonally: Provide estimates for jurisdictional waters in the review area (check all that apply): Tributary waters: linear feet width (ft). Other non - wetland waters: acres. Identify type(s) of waters: 3. Non -RPWs8 that flow directly or indirectly into TNWs. Waterbody that is not a TNW or an RPW, but flows directly or indirectly into a TNW, and it has a significant nexus with a TNW is jurisdictional. Data supporting this conclusion is provided at Section III.C. Provide estimates for jurisdictional waters within the review area (check all that apply): Tributary waters: linear feet width (ft). Other non - wetland waters: acres. Identify type(s) of waters: 4. Wetlands directly abutting an RPW that flow directly or indirectly into TNWs. Wetlands directly abut RPW and thus are jurisdictional as adjacent wetlands. Wetlands directly abutting an RPW where tributaries typically flow year- round. Provide data and rationale indicating that tributary is perennial in Section III.D.2, above. Provide rationale indicating that wetland is directly abutting an RPW: Wetlands have direct hydrologic connectin to stream. Wetlands directly abutting an RPW where tributaries typically flow "seasonally." Provide data indicating that tributary is seasonal in Section 1IL13 and rationale in Section III.D.2, above. Provide rationale indicating that wetland is directly abutting an RPW: Provide acreage estimates for jurisdictional wetlands in the review area: 1.18 acres. 5. Wetlands adjacent to but not directly abutting an RPW that flow directly or indirectly into TNWs. Wetlands that do not directly abut an RPW, but when considered in combination with the tributary to which they are adjacent and with similarly situated adjacent wetlands, have a significant nexus with a TNW are jurisidictional. Data supporting this conclusion is provided at Section III.C. Provide acreage estimates for jurisdictional wetlands in the review area: acres. 6. Wetlands adjacent to non -RPWs that flow directly or indirectly into TNWs. Wetlands adjacent to such waters, and have when considered in combination with the tributary to which they are adjacent and with similarly situated adjacent wetlands, have a significant nexus with a TNW are jurisdictional. Data supporting this conclusion is provided at Section III.C. Provide estimates for jurisdictional wetlands in the review area: acres. 7. Impoundments of jurisdictional waters.9 As a general rule, the impoundment of a jurisdictional tributary remains jurisdictional. 0 Demonstrate that impoundment was created from "waters of the U.S.," or ❑ Demonstrate that water meets the criteria for one of the categories presented above (1 -6), or ❑ Demonstrate that water is isolated with a nexus to commerce (see E below). E. ISOLATED [INTERSTATE OR INTRA- STATE] WATERS, INCLUDING ISOLATED WETLANDS, THE USE, DEGRADATION OR DESTRUCTION OF WHICH COULD AFFECT INTERSTATE COMMERCE, INCLUDING ANY SUCH WATERS (CHECK ALL THAT APPLY): 10 Tn which are or could be used by interstate or foreign travelers for recreational or other purposes. ❑ from which fish or shellfish are or could be taken and sold in interstate or foreign commerce. ❑ which are or could be used for industrial purposes by industries in interstate commerce. Interstate isolated waters. Explain: Other factors. Explain: Identify water body and summarize rationale supporting determination: 'See Footnote # 3. 'To complete the analysis refer to the key in Section IILD.6 of the Instructional Guidebook. 10 Prior to asserting or declining CWA jurisdiction based solely on this category, Corps Districts will elevate the action to Corps and EPA HQ for review consistent with the process described in the Corps /EPA Memorandum Regarding CWA Act Jurisdiction Following Rapanos. Provide estimates for jurisdictional waters in the review area (check all that apply): Tributary waters: linear feet width (ft). Other non - wetland waters: acres. Identify type(s) of waters: Wetlands: acres. F. NON - JURISDICTIONAL WATERS, INCLUDING WETLANDS (CHECK ALL THAT APPLY): If potential wetlands were assessed within the review area, these areas did not meet the criteria in the 1987 Corps of Engineers Wetland Delineation Manual and /or appropriate Regional Supplements. Review area included isolated waters with no substantial nexus to interstate (or foreign) commerce. ❑ Prior to the Jan 2001 Supreme Court decision in "SWANCC," the review area would have been regulated based solely on the "Migratory Bird Rule" (MBR). Waters do not meet the "Significant Nexus" standard, where such a finding is required for jurisdiction. Explain: Other: (explain, if not covered above): Provide acreage estimates for non - jurisdictional waters in the review area, where the sole potential basis of jurisdiction is the MBR factors (i.e., presence of migratory birds, presence of endangered species, use of water for irrigated agriculture), using best professional judgment (check all that apply): Non - wetland waters (i.e., rivers, streams): linear feet width (ft). Lakes /ponds: acres. Other non - wetland waters: acres. List type of aquatic resource: Wetlands: acres.

EXECUTIVE SUMMARY The City of Fayetteville has retained WK Dickson to evaluate the Buckhead Creek watershed for existing flooding as well as water quality and erosion problems and to recommend improvements for addressing identified issues. The goal of this project is to identify the capital improvements that will increase the level of service of drainage systems within the Buckhead Creek watershed and to reduce the frequency and severity of flooding for private residents. The headwaters of Buckhead Creek originate in the vicinity of Cross Creek Mall north of Morganton Road. The creek generally flows south beyond the City of Fayetteville municipal limits before discharging to Little Rockfish Creek. The portion of Buckhead Creek within City limits is generally bordered by single family residential properties on either side with pockets of commercial development. Over 70 structures adjacent to the creek are located within the FEMA 100 -year effective floodplain of Buckhead Creek. The majority of those structures are also at risk of flooding during more frequent storm events. In addition to the flooding concerns along Buckhead Creek, fourteen (14) other areas were identified throughout the watershed by City staff and private residents as having flooding problems. These areas are located along conveyance systems that drain to Buckhead Creek and in areas where no centralized conveyance system exists. Flooding problems in these systems range from road inundation to finished floor flooding in some instances. For the purposes of this study, the main stem of Buckhead Creek is defined as the Primary System and all other areas are noted as Secondary Systems. WK Dickson evaluated the hydrologic and hydraulic characteristics of the Buckhead Creek watershed to determine the existing flooding conditions for Buckhead Creek and the fourteen (14) secondary systems. These findings, along with flood mitigation recommendations, are included in this report. Capital costs were estimated for each proposed project to assist City staff in making planning level decisions and prioritizing improvements. The recommended projects are described below: Primary System • Ferncreek Floodplain Bench and Floodwall: The Ferncreek Floodplain Bench and Floodwall is proposed to reduce the frequency and severity of residential flooding along Buckhead Creek in the Windtree and Buckhead subdivisions from Lost Tree Court to the Buckhead Villas. The floodwall provides flood protection for several houses along the right bank that otherwise would have structural flooding during the 25 -year storm event and the floodplain bench will reduce the frequency and severity of yard flooding for properties along Ferncreek Drive. • Raeford Road Culvert: Raeford Road is an NCDOT maintained road located approximately in the middle of the watershed. The road does not overtop during the 100 -year storm event, however the roadway embankment is approximately 20 feet high causing water to backup behind the road causing upstream flooding. An additional 60" RCP under Raeford Road will significantly reduce residential flooding along Stoneykirk Drive and the portion of the Buckhead Subdivision immediately upstream of the railroad tracks. While increasing the conveyance under Raeford Road Buckhead Creek Watershed Study Page ES -1 WK Dickson & Co., Inc. EXECUTIVE SUMMARY would significantly reduce flooding upstream of Raeford Road, water surface elevations would increase downstream of Raeford Road for portions of Buckhead Creek. The majority of those increases would not cause structural flooding; however increased levels of yard flooding may occur as a result of the Raeford Road Culvert project. Extensive coordination with NCDOT would be required to facilitate the design and construction of the project. • Raeford Road Floodplain Bench: The Raeford Road Floodplain Bench is located immediately downstream of Raeford Road and includes excavation of material within the floodplain for approximately 600 linear feet to increase the floodplain storage and reduce water surface elevations. The floodplain bench will reduce the tailwater of the Raeford Road Culvert thereby reducing water surface elevations upstream of the culvert somewhat. • Coventry Road Culvert and Floodplain Bench: The proposed Coventry Road culvert includes leaving the existing culverts in place and adding two floodplain box culverts along the left overbank to convey additional flow and provide a 25 -year level of service through the culvert. The proposed culvert will significantly lower water surface elevations upstream of Coventry Road reducing the frequency and severity of flooding for several residences along Odom Drive. The proposed culvert and floodplain bench will also reduce flooding for several residences along Coventry Road. • Devonshire Drive Floodplain Bench and Glenwick Drive Berm: The Devonshire Drive Floodplain Bench and Glenwick Drive Berm will offset some of the increases in water surface caused by the Raeford Road Culvert improvements. The Devonshire Drive floodplain bench will likely result in wetland impacts that may require mitigation. The Glenwick Drive Berm will protect several properties along Glenwick Drive during the 25 -year storm event. • Lake Francis Wetland Enhancement/Restoration: Three of the five projects identified for reducing flooding along Buckhead Creek will likely cause wetland impacts that may require mitigation. While mitigation can typically be offset paying fees -in -lieu to the State of North Carolina Ecosystem Enhancement Program (NCEEP) or a private banker, mitigation can also be completed through restoration and enhancement. Lake Francis has been breached, however a significant open body of water still exists. By removing the remainder of the dam and any downstream beaver dams, the lake could be restored to a wetland which would likely provide mitigation credits. The cumulative benefit of the proposed Primary System projects includes the following: • Reduction in water surface elevations during the 25 -year storm event for 79 residential or commercial structures. • The level of service improved to a less frequent storm event for 64 of the 79 structures. • The level of service at Coventry Road improved from a 2 -year level of service to a 25- Buckhead Creek Watershed Study Page ES -2 WK Dickson & Co., Inc. EXECUTIVE SUMMARY year level of service. • The level of service at the railroad improved from a 2 -year level of service to a 10- year level of service. Impacts from the proposed Primary System projects include increases in water surface elevations for six (6) properties, although the storm event where structural flooding occurs has not changed. Three of the six properties are located on a tributary to Buckhead Creek where the flood risk is more attributed to the tributary than to Buckhead Creek. The depth of yard flooding may increase for additional properties, but the width of the floodplain would not significantly increase. With the exception of the Ferncreek Drive Floodplain Bench and Floodwall, the remainder of the proposed projects will require FEMA approval through a Conditional Letter of Map Revision (CLOMR) prior to construction. Each of the proposed projects is expected to require a 401/404 permit and could potentially require wetland mitigation as described above. If wetland impacts exceed 0.5 acre, which is likely for the Ferncreek Drive Floodplain Bench, Raeford Road Floodplain Bench, and the Devonshire Drive Floodplain Bench, an Individual Permit (IP) will likely be required from the Army Corps. Individual Permits typically require a lengthy review time. Table ES -1 below shows the prioritization of the Primary System projects along with preliminary cost estimates and estimated design and permitting timeframes. Cost estimates include potential mitigation costs, administrative, legal, surveying, and engineering costs. Cost estimates are based on 2009 dollars and should be updated during the design process. Timeframes may vary based on regulatory agency reviews and easement negotiations /acquisition. All timeframes and cost estimates assume projects will be designed, permitted, and constructed individually. Combining the design and permitting of multiple projects may provide increased efficiencies and cost savings to the City. Table ES -1: Primary System Prioritization and Cost Prioritization Project Cost Estimated Design /Permitting Timeframe 1 Coventry Road Culvert and Floodplain $866,100 12 months Bench 2 Raeford Road Floodplain Bench $906,400 18 months 3 Devonshire Drive Floodplain Bench and $421,400 18 months Glenwick Drive Berm 4 Raeford Road Culvert $352,700 12 months 5 Femcreek Floodplain Bench and Floodwall $749,600 18 months 6 Lake Francis Wetland $423,400 12 months Enhancement/Re storation The proposed prioritizations attempt to balance project benefits with potential impacts such as increasing downstream water surface elevations or wetland impacts. As discussed above, the Raeford Road culvert will provide the most overall benefit from a flood reduction perspective; however the proposed culvert will also generate downstream impacts that should Buckhead Creek Watershed Study Page ES -3 WK Dickson & Co., Inc. EXECUTIVE SUMMARY be considered. If the City elects to use the Lake Francis project for mitigation, then construction of the Lake Francis Wetland Enhancement/Restoration will be required prior to any projects resulting in wetland impacts that require mitigation. Secondary Systems Developing flood mitigation alternatives for the secondary systems typically included increases in pipe capacity and /or rerouting flows where more space was available for improvements. The projects described below are the recommended alternatives for each of the secondary systems. In some instances, the full benefit of the proposed improvements may not be realized unless the proposed primary system improvements along Buckhead Creek are completed since several of the secondary systems are affected by backwater from Buckhead Creek. • Buckhead Kingsford: The Buckhead Kingsford improvements reduce flooding for properties along Levenhall Drive, Murray Hill Road, and Ferncreek Drive. Properties near the outlet of the system along Ferncreek Drive and Humboldt Place may still have flooding during the 10 -year event due to backwater from Buckhead Creek unless the Raeford Road Culvert improvements are completed. • Broyhill Road: The Broyhill Road improvements include additional inlets and pipe improvements to reduce the frequency and severity of flooding in the intersection of Broyhill Road and Ferncreek Drive. • Ferncreek Norwood: The Ferncreek Norwood improvements will help alleviate crawl space flooding at 4364 Ferncreek Drive and provide a 10 -year level of service for the system. • Westwood: The Westwood System improvements will reduce roadway and nuisance flooding in the Westwood subdivision. A portion of the runoff will be rerouted along Palomar Street and Rushmore Drive to reduce private property impacts and increase accessibility to the system for maintenance. • Raeford Faison: The proposed improvements to alleviate roadway and structural flooding along Faison Avenue include a new conveyance system that will reroute storm flows south along Faison Avenue and tie into an existing 60" system that conveys flows west under Ireland Drive and ultimately to Buckhead Creek. The proposed system will provide a 10 -year level of service. • Montclair: Proposed improvements in the Montclair subdivision include increasing the size of approximately 500 linear feet of pipe at the downstream end of the system in the vicinity of Stoneykirk Drive. The improvements at the downstream end of the system will improve the level of service throughout the remainder of the system along Wellington Drive, Montclair Road, and Belford Road. Buckhead Creek Watershed Study Page ES-4 WK Dickson & Co., Inc. EXECUTIVE SUMMARY Coventry Road: The Coventry Road improvements include increasing the size of the existing pipe between 4314 and 4318 Coventry Road to reduce yard flooding. Roxie Avenue: The Roxie Avenue is the largest secondary system in the watershed draining over 1 square mile including the Cumberland County Hospital, medical office buildings, and residential subdivisions. The proposed improvements include rerouting drainage with new infrastructure and increasing the size of existing infrastructure to reduce the frequency and severity of flooding along Roxie Avenue, Martindale Drive, Faison Avenue, and Village Drive in the vicinity of Brentwood Drive. • Ashton Road Ramblewood Drive: Installing additional inlets along Ashton Road and increasing the size of the pipes at the downstream end of the system will increase the capture and conveyance of runoff. This increased capture and capacity of the system will reduce the frequency and severity of residential flooding along Ashton Road. • Ashton Road Friar Avenue: The proposed improvements include a now splitter at the intersection of Friar Avenue and Ashton Road that will divert a portion of the drainage to a new system along Park Knoll Drive. The new system along Park Knoll Drive will include a new outfall that directs drainage towards the upper end of Lake Francis. • Ashton Road: The Ashton Road improvements will reduce the frequency and severity of flooding for residents at 1821 Ashton Road by collecting additional drainage through new inlets and conveying that drainage through an increased outfall pipe towards Buckhead Creek. • Kimberly Drive: The Kimberly Drive improvements include parallel 24" pipes to the existing culvert that will help provide a 25 -year level of service for the roadway. The additional culvert will also decrease water surface elevations upstream of the culvert reducing the frequency and severity of residential flooding to the surrounding property owners.

SECTION 1 BACKGROUND AND INTRODUCTION 1.1 Project Description The City of Fayetteville implemented a stormwater utility in 1995 to provide the funding for the City's stormwater infrastructure and management policies. This utility provides the means by which the City is able to meet the federal mandate resulting from the 1987 Clean Water Act and to satisfy the requirements of the City's National Pollutant Discharge Elimination System (NPDES) permit, which are primarily related to the improvement of water quality. In 2007, the City elected to implement an additional stormwater "drainage" fee that would be utilized to maintain the existing stormwater infrastructure and fund the planning, design, and implementation of flood control projects. As part of the City's initiative to reduce flooding, the City retained WK Dickson to evaluate the Buckhead Creek watershed for existing flooding problems and to recommend improvements for addressing identified issues. This report was prepared for the City of Fayetteville as part of the Buckhead Creek Watershed Study. Buckhead Creek is located in the western portion of Fayetteville and generally drains from north to south ultimately discharging to Little Rockfish Creek as shown in Figure 1 -1. The Study includes an evaluation of Buckhead Creek from Cross Creek Mall at the upstream end of the study to approximately 1,000 feet downstream of Cumberland Road, as well as numerous drainage systems that drain to Buckhead Creek within this reach. For the purposes of this report, Buckhead Creek will be noted as the Primary System and the drainage systems that drain to Buckhead Creek will be noted as Secondary Systems. The locations of the systems evaluated in this Study are shown in Figure 1 -2. The primary goal of the Buckhead Creek Watershed Study is to reduce flooding risks through the watershed and to "safeguard the public welfare through the proper collection, conveyance, and storage of stormwater runoff in a non - damaging and non -life threatening manner," as described on the City's website. Additional project goals include stream stabilization and improving the quality of the stormwater runoff. Buckhead Creek Watershed Study Page 1 -1 WK Dickson & Co., Inc. SECTION 1 BACKGROUND AND INTRODUCTION 1.2 Watershed Characteristics and History of Drainage Problems The Buckhead Creek watershed shown in Figure 1 -2 is approximately 5.2 square miles in area between the upstream boundary near Cross Creek Mall and the City of Fayetteville limits in the vicinity of Cumberland Road. Buckhead Creek continues flowing southward beyond the City boundary before discharging to Little Rockfish Creek and ultimately to the Cape Fear River. Land use in the watershed is primarily built -out as shown on the Land Use Map in Appendix C. For this reason, the existing conditions land use was assumed to be the future conditions land use obtained from the City's zoning maps. Development within the watershed is approximately 50% residential with significant commercial areas around the headwaters including Cross Creek Mall and along Raeford Road. North Carolina Department of Transportation (NCDOT) maintained right -of -way (ROW) composes a significant portion of the watershed as well including All- American Expressway, Morganton Road, Cliffdale Road, Raeford Road, and Cumberland Road. Soils within the watershed are predominantly NRCS hydrologic soil groups A and B as shown in Appendix C. While the watershed is located in the Sandhills region of North Carolina, the dense development in the watershed somewhat limits the natural Sandhills soil conditions that are conducive to high levels of infiltration. A list of drainage problems in the Buckhead Creek watershed was obtained from feedback provided by property owners at a public meeting and through questionnaires as well as input from City Staff. The questionnaires were mailed in September of 2008 as well as posted on the City's website and included questions regarding the frequency, location, and severity of flooding. Approximately 170 surveys were completed through the online submission form or by filling out the paper survey and returning it to WK Dickson. Questionnaire results were georeferenced and are shown in Figure 1 -3. An example of the questionnaire and tabulated questionnaire results are shown in Appendix D. Feedback from the questionnaires and the public meeting were instrumental in identifying the flooding problem areas in the watershed that required detailed analysis. A detailed description of the existing drainage problems is included in Section 2. Buckhead Creek Watershed Study Page 1 -4 WK Dickson & Co., Inc. SECTION 1 BACKGROUND AND INTRODUCTION 1.3 Stormwater Guidelines and Design Requirements in Based on guidelines provided in the City of Fayetteville Minimum Design Standards for Storm Drainage, the following standards and criteria were used to evaluate the existing drainage system: Table 1 -1: Citv of Fayetteville Design Standards and Criteria Drainage Type Design Storm Project Area (years) Buckhead Kingsford Broyhill Ferncreek Norwood Westwood Raeford Faison Storm Drainage System 10 Montclair Odom Drive Coventry Roxie Avenue Ashton Road Ramblewood Drive Ashton Road Friar Avenue Ashton Road Open Channels 25 Buckhead Creek Culverts (Subdivision Streets) Coventry Road 25 Kimberly Drive Morganton Road Culverts (Thoroughfare Roads) Cliffdale Road 50 Raeford Road Cumberland Road Rainfall depths for the design storms above can be found in Appendix A. Buckhead Creek Watershed Study Page 1 -6 WK Dickson & Co., Inc. SECTION 2 EXISTING CONDITIONS 2.1 Buckhead Creek Primary System For the purposes of this Study, Buckhead Creek was subdivided into six reaches based on road crossings and areas at risk of flooding. The reaches from upstream to downstream are as follows: • Reach 1 — Headwaters to Cliffdale Road. • Reach 2 — Cliffdale Road to railroad. • Reach 3 — Railroad to Raeford Road. • Reach 4 — Raeford Road to Coventry Road. • Reach 5 — Coventry Road to Lake Francis. • Reach 6 — Lake Francis dam to limits of study downstream of Cumberland Road. The existing 25- and 100 -year floodplains along with the limits of each reach defined above are shown in Figures 2 -1 through 2 -4. The mapped floodplains are based on the model results of this Study and may differ from the published FEMA floodplains. For flood insurance purposes, the effective FEMA floodplains should be referenced. 2.1.1 Reach 1 Buckhead Creek upstream of Cliffdale Road is predominantly a man - altered channel with adequate channel capacity for the 25 -year storm event. Culvert crossings at Morganton Road and Cliffdale Road appear to be sized appropriately based on model results as shown in Table 2 -1 below. There are no known areas of significant flooding upstream of Cliffdale Road. Table 2 -1: Existing Structures at Roadwav Crossings Buckhead Creek Watershed Study Page 2 -1 WK Dickson & Co., Inc.

The bank erosion is likely occurring due to high velocity flows as the floodplain is relatively narrow and the 100 -year storm is conveyed within the channel. Approximately 1,000 feet downstream of Cliffdale Road, a low flow channel forms allowing floodplain access. While the floodplain access allows for a more stable stream, residential flooding occurs intermittently along this reach to the railroad tracks during the 10 -year storm event. Table 2 -2 shows the residences along Buckhead Creek that are at risk of at least crawl space flooding during storm events more frequent than the 25 -year event. The lowest adjacent grade (LAG) elevations shown in the table are based on the State of North Carolina's LiDAR data and not based on survey data. LAG flooding may not result in finished floor flooding, but is indicative of structures at risk of flooding. Questionnaire results show three (3) houses with finished floor flooding, two (2) houses with AC unit and /or storage building flooding, and two (2) houses with crawl space flooding along Buckhead Creek between Cliffdale Road and the railroad tracks. Multiple residents reported yard flooding in this same area. The majority of this reach has not been mapped by FEMA with the exception of approximately 2,000 feet of stream upstream of the railroad tracks. Intermittent wetlands exist along the stream between Cliffdale Road and the railroad tracks and will be taken into consideration for any potential flood mitigation improvements. Exhibit 2 -1.

Coordinate System: North Carolina State Plane NAD 83 Feet SECTION 2 EXISTING CONDITIONS 2.1.3 Reach 3 The stream between the railroad tracks and Raeford Road causes significant residential flooding to several houses along Stoneykirk Road along the stream's right overbank. Property lots on the left bank are largely undeveloped with the exception of the lots on Raeford Road which have been commercially developed and do not appear to have flooding issues. Based on the questionnaire results two homes on Stoneykirk Road have experienced finished floor flooding and one home has had AC unit and /or storage building flooding. Numerous other structures along Stoneykirk Road have likely experienced significant yard flooding based on the model results. The modeled 25 -year and 100 -year existing conditions floodplains are shown in Figure 2 -2. Backwater from Raeford Road is a significant contributor to the flooding along this portion of Buckhead Creek. While Raeford Road does not appear to overtop during the 100 -year storm event, the 20 -foot high embankment backs water up past the railroad tracks and into the Buckhead subdivision. The backwater effect from Raeford Road during the 25 -year storm extends approximately 3,000 feet upstream of Raeford Road in the vicinity of the intersection of Ferncreek Drive and Ambrose Place. Table 2 -1 details the existing culverts at Raeford Road and the existing level of service. 2.1.4 Reach 4 Between Raeford Road and Coventry Road, Buckhead Creek typically conveys a storm event smaller than the 2 -year storm. Since the floodplain is accessed in most significant storm events, the stream is stable except in spot locations immediately downstream of Raeford Road. Residential properties are located on the right overbank along Alleghany Road and Odom Drive. The left overbank is either undeveloped or part of the Douglass Byrd High School property. No flooding concerns were reported for the majority of the reach, however approximately 1,000 feet upstream of Coventry Drive, two residents reported finished floor flooding and one resident reported AC unit and /or storage building flooding. Based on model results and questionnaire feedback it appears that storm flows from Buckhead Creek overflow at a low spot on Odom Drive on the west side of the creek. As shown in Table 2 -1, Coventry Road currently has a 2 -year level of service. Storms larger than the 2 -year storm overtop the road immediately west of the box culverts. Flows overtopping the road and storm flows on the downstream end of the culvert where the 10 -year storm overtops the west bank both appear to cause flooding at 4501 Coventry Road. The modeled 25 -year and 100 -year existing conditions floodplains are shown in Figure 2 -3.

A portion of the stream and wetland system (approximately 1,000 feet) was restored in 2000 as part of a mitigation plan for stream improvements on a tributary to Buckhead Creek. Approximately 4,500 feet downstream of Coventry Road, Buckhead Creek transitions from the braided stream and wetland to a small body of open water with a wetland perimeter, formerly called Lake Francis. Lake Francis Dam is currently breached as shown in Exhibit 2 -2 along the right abutment looking downstream, which has lowered the water level of the lake, thereby reducing the area of open Exhibit 2 -2. Lake Francis Breach water. Structural flooding along Buckhead Creek between Coventry Road and the breached dam appears to be limited based on questionnaire feedback, however significant yard flooding has occurred on two properties along Glenwick Drive in the vicinity of the stream restoration project. Two properties along Village Drive near the previous limits of Lake Francis have experienced significant finished floor flooding and /or crawl space flooding. These two properties are located on a tributary to Buckhead Creek; however backwater from Buckhead Creek may contribute to the flooding. The modeled 25 -year and 100 -year existing conditions floodplains are shown in Figure 2 -4. 2.1.6 Reach 6 Immediately downstream of the breached dam is a wetland area with several beaver dams transitioning to a defined channel upstream of Cumberland Road. The culverts at Cumberland Road have recently been upgraded during a roadway widening project providing a 50 -year level of service for the NCDOT maintained road. Based on model results and questionnaire responses, there is no significant structural flooding downstream of the breached dam to the project limits.

"t t l . 1`i IL, .. y SECTION 2 EXISTING CONDITIONS 2.2 Buckhead Creek Secondary Systems While Buckhead Creek is the primary source of flooding within the watershed, undersized secondary systems can also lead to significant structural and roadway flooding. Based on the questionnaire responses, public meeting, and feedback from City staff, fourteen (14) secondary systems were identified for further evaluation. Secondary systems are defined as drainage systems conveying stormwater flows to Buckhead Creek. For reporting purposes the secondary systems were grouped together into six different locations as follows: • All American Expressway — Includes systems in the vicinity of All American Expressway including the Buckhead, Kingsford, and Westwood subdivisions. • Raeford Road — Includes systems in the vicinity of Raeford Road including the Montclair subdivision and drainage along McPherson Church Road and Raeford Road. • Odom Drive — Includes drainage along Odom Drive and Coventry Road. • Roxie Avenue — Includes drainage from Cumberland County Hospital and the nearby medical facilities as well drainage from the residential neighborhoods on Roxie Avenue, Faison Avenue and the surrounding areas. • Sherwood Park — Sherwood Park is a subdivision in the southwest section of the watershed and includes systems along Ashton Road. • Kimberly Drive — Includes drainage from the Pine Acres and Welmar Heights subdivisions. 2.2.1 All American Expressway Buckhead Kingsford System The Buckhead Kingsford System collects drainage from approximately 195 acres in the Buckhead and Kingsford subdivisions and discharges to Buckhead Creek upstream of the railroad tracks. The conveyance system is primarily comprised of closed pipes although open ditches are located along the All American Expressway and the railroad tracks. Exhibit 2 -3 shows where drainage from Ferncreek Drive is discharged into an open channel between 605 Humbolt Place and 610 Longwood Place prior to entering the open channel along the railroad tracks. Responses from the public Exhibit 2 -3. Open channel downstream of Ferncreek questionnaires include crawl space Drive Buckhead Creek Watershed Study Page 2 -10 WK Dickson & Co., Inc. SECTION 2 EXISTING CONDITIONS flooding along Levenhall Drive, Murray Hill Road, and Ferncreek Drive. One resident on Murray Hill Road and one resident on Ferncreek Drive indicated that their properties had suffered finished floor flooding as well. In addition to structural flooding, several properties in the area also had yard flooding. Model results corroborate the responses from the public questionnaires as the areas listed above do not provide a 10 -year level of service, which is the design storm size for this system. Flooding along Levenhall Drive in the Kingsford subdivision is partially due to an undersized drainage system, and partially due to backwater from the All American Expressway. Flooding along Ferncreek Drive in the Buckhead subdivision is partially due to an undersized drainage system, and partially due to backwater from Buckhead Creek. The backwater elevations from Buckhead Creek are primarily the result of storage behind Raeford Road as described in the Reach 3 section above. BroSystem The Broyhill System is a small closed pipe system in the Buckhead subdivision that drains directly into Buckhead Creek upstream of the railroad tracks. The existing system drains Broyhill Road with a series of 15" pipes to the intersection with Ferncreek Drive where the conveyance system increases in size to 24 ". Responses from the public questionnaires indicate flooding occurs at the intersection of Broyhill Road and Ferncreek Drive. The resident at 4317 Ferncreek Drive reported finished floor flooding, however flooding at that location is likely due to backwater from Buckhead Creek. Model results show that the Broyhill System does not currently convey a 2 -year storm. Backwater from Buckhead Creek contributes significantly to the flooding in this area; however the pipe system is undersized to convey the 10 -year storm regardless of the backwater condition. Ferncreek Norwood System The Ferncreek Norwood System is located approximately 1,000 feet north of the Broyhill System. The closed drainage system, consisting of 15" RCP, conveys runoff from Norwick Drive across Ferncreek Drive and west towards Buckhead Creek. The pipe conveying now from Norwick Drive is located on the property line between 4364 Ferncreek Drive and 4360 Ferncreek Drive. The resident located at 4364 Ferncreek Drive reported crawl space flooding. Model results indicate minimal flooding during the 2 -year storm event, but more substantial flooding during the 10 -year storm event. Backwater from Buckhead Creek will likely effect the hydraulic performance of the system, particularly for the 10 -year event, however the system is undersized regardless of the backwater condition. Westwood System The Westwood System is located in the Westwood subdivision, north of Cliffdale Road. The closed drainage system consists of pipes ranging in size between 15 "- 30" and discharging to an open ditch immediately upstream of the All American Expressway. Feedback from the public questionnaires reported road flooding occurs throughout the subdivision and yard flooding occurs for the properties adjacent to the All American Expressway. Model results indicate the system does not meet a 2 -year level of service. Backwater from the All American Expressway contributes to the flooding, although the conveyance system is undersized and Buckhead Creek Watershed Study Page 2-11 WK Dickson & Co., Inc. SECTION 2 EXISTING CONDITIONS does not provide a 10 -year level of service. 2.2.2 Raeford Road Raeford Faison System The Raeford Faison System is located at the intersection of Raeford Road and Faison Avenue. The existing conveyance system consists of 15" pipes collecting drainage along Faison Avenue and connecting to larger conveyance system along Raeford Road. According to questionnaire responses and digital photographs, several properties along Faison Avenue have suffered structural and yard flooding on a somewhat frequent basis since the widening of Raeford Road. Exhibit 2 -4 shows the standing water adjacent to a structure along Faison Avenue after a rain event. Based on model results backwater from the Raeford Road system is the predominant cause of flooding at this location. Floodwaters will not recede until the downstream water surface elevations decrease in the conveyance system along Raeford Road. Exhibit 2 -4. Faison Avenue Flooding Montclair System The Montclair System is located in the Montclair subdivision north of Raeford Road and west of Buckhead Creek. The existing closed pipe conveyance system is predominantly located within the right -of -way along Belford Road, Wellington Drive, and Montclair Road. Drainage is then conveyed between 833 Montclair Road and 837 Montclair Road and crosses under Stoneykirk Drive before discharging to Buckhead Creek. Several residents reported yard and roadway flooding along Belford Road and Wellington Drive and one resident reported finished floor flooding along Wellington Drive. Belford Road appears to be particularly floodprone between Newport Road and Montclair Road where a significant depressional area is located in the middle of the road. Model results indicate that the existing system does not provide a 2 -year level of service. Backwater from Buckhead Creek will significantly affect the hydraulic performance of the conveyance system. McPherson Church System The McPherson Church System is a pipe system located northwest of the intersection of South McPherson Church Road and Raeford Road and runs along South McPherson Church Road. The existing conveyance system consists of drainage pipes along South McPherson Church Road that discharge to a small detention basin west of the road. The pond does not Buckhead Creek Watershed Study Page 2 -12 WK Dickson & Co., Inc. SECTION 2 EXISTING CONDITIONS have a suitable outlet which can cause flooding at 988 South McPherson Church Road. Based on discussions with the City, the property with the detention pond will be developed in the near future and the developer of that site will be responsible for the design and construction of a conveyance system that meets City standards. 2.2.3 Odom Drive Odom Drive System The Odom Drive System includes two independent closed drainage systems that collect drainage along Odom Drive and west of Odom Drive and convey that drainage to Buckhead Creek on the east side of Odom Drive. The northernmost system consists of 15 "- 24" RCPs along Redwood Drive and the southernmost system consists of 18" RCPs draining Devonshire Drive and crossing through private properties prior to conveying drainage under Odom Drive and into Buckhead Creek. The existing 24" outfall to Buckhead Creek east of Redwood Drive is currently damaged, limiting the discharge from the pipe. The resident at 1308 Odom Drive reported finished floor flooding during rain events. Several residents in the area reported significant flooding along Odom Drive in the vicinity of 1308 Odom Drive. The Redwood Drive system would currently provide a 10 -year level service if the outfall pipe was in good condition. The system draining Devonshire Drive provides a level of service less than the 2 -year storm event, which is primarily due to backwater from Buckhead Creek which overtops Odom Drive during the 10 -year storm event. CoventrySystem The Coventry System is a closed pipe system that collects drainage from Ireland Drive and conveys it southwest along Coventry Road. The 24" outfall pipe is located between 4314 and 4318 Coventry Road and discharges to a small drainage ditch that flows into Buckhead Creek. The residents at 4314 and 4318 Coventry Road reported yard flooding during rain events which may be partially due to the existing topography as the properties are lower than Coventry Road. Model results indicate minimal flooding occurs during a 2 -year storm event, but that the system is significantly undersized to convey runoff from the 10 -year storm event. 2.2.4 Roxie Avenue Roxie Avenue System The Roxie Avenue System collects drainage from approximately 1.2 square miles, ultimately discharging to Buckhead Creek upstream of Lake Francis. The drainage area consists of several residential neighborhoods including Welmar Heights, Bordeaux, and Evergreen Estates. Medical office buildings and the Cumberland County Hospital are also located in the watershed. The City has completed drainage improvements to reduce flooding in the watershed in the past including triple 36" RCPs between Sandra Drive and Wellons Drive as well as hardened stream improvements in the vicinity of Ireland Drive. Flooding problems identified in the watershed by City staff and resident feedback include the following: • Flooding along Faison Avenue between Joel Street and Crestwood Street - There is currently no defined drainage system along Faison Avenue in this location Buckhead Creek Watershed Study Page 2 -13 WK Dickson & Co., Inc. SECTION 2 EXISTING CONDITIONS which contributes significantly to the flooding in this location. • AC unit and /or storage building flooding at 900 Rodie Avenue — Model results indicate the drainage systems along Rodie Avenue and Faison Avenue are undersized for the 10 -year event. • Roxie Avenue Road flooding — Multiple residents have reported significant road flooding along Roxie Avenue near the intersection with Elizabeth Drive. The roadway was impassable to traffic as recently as the summer of 2008 due to flooding. The existing conveyance system includes a 24" RCP and 30" RCP conveying flows south along Roxie Avenue to Furman Drive. Model results validate the anecdotal information as the system is undersized for the 10 -year storm event. • AC unit and /or storage building flooding at 1630 Sandra Drive — Downstream of this location, the City installed triple 36" RCP's that drain to a 6' x 4' box culvert under Wellons Drive. The resident at 1630 Sandra Drive reported flooding up to their porch stairs after these improvements were installed. • Martindale Drive roadway flooding and basement flooding at 1211 Martindale Drive — The channel behind 1211 Martindale Drive was hardened with increased channel capacity, however basement flooding occurred in September of 2008 after these improvements were installed. • Finished floor flooding at 3942 Village Drive — A 24" RCP between 4002 Village Drive and 3942 Village Drive conveys drainage from Brentwood Drive. Flooding may be caused either an undersized drainage system or lack of suitable drainage inlets. • Structural flooding along Village Drive near intersection with Dellwood Drive — Approximately 700 feet upstream of the confluence of the tributary with Buckhead Creek, two residents along Village Drive reported significant finished floor and crawl space flooding. The stream draining towards Buckhead Creek is located approximately 60 feet behind the two houses. Backwater from Buckhead Creek may contribute to the flooding at this location 2.2.5 Sherwood Park Systems Ashton Road Ramblewood Drive System The Ashton Road Ramblewood Drive System is located in the Sherwood Park subdivision between Ashton Road and Wingate Road. The closed pipe system drains approximately 60 acres with pipes ranging in size between 18" and 36 ". The resident at 1937 Ashton Road reported finished floor flooding during rain events. Based on City feedback and the responses from the questionnaires only the downstream portion of the system was evaluated for hydraulic capacity. Model results indicate that the system does not currently provide a 2 -year level of service. The existing curb and gutter is a rolled asphalt curb that will not capture as much runoff into the drainage system as a concrete curb and gutter system. In addition to undersized pipes, flooding at 1937 Ashton Road could be occurring due to runoff from Ramblewood Drive that is not captured in the drainage system and could potentially overtop the asphalt curb flowing directly to the house. Buckhead Creek Watershed Study Page 2 -14 WK Dickson & Co., Inc. SECTION 2 EXISTING CONDITIONS Ashton Road Friar Avenue System The Ashton Road Friar Avenue System is located in the Sherwood Park subdivision in the vicinity of the intersection of Ashton Road and Friar Avenue. The closed pipe system drains approximately 30 acres before discharging to Buckhead Creek through a 30" RCP between 2214 and 2218 Skyview Drive. Based on questionnaire responses, flooding in the area appears to be concentrated near the intersection of Ashton Road and Friar Avenue. Model results indicate the system downstream of Ashton Road meets a 2 -year level of service; however the areas along Ashton Road and upstream of Ashton Road do not meet a 2 -year level of service. The portion of the system downstream of Ashton Road is predominantly located on private property and turns several times to remain on the parcel lines. The turns in the system cause headlosses and may be contributing to the upstream flooding. Ashton Road System The Ashton Road System is located approximately 350 feet south of the intersection of Strathmore Avenue and Ashton Road. A 15" drainage line collects drainage from the surrounding homes and Ashton Road. The resident at 1821 Ashton Road has reported crawl space flooding on several occasions. Based on visual inspection the elevation of the house at 1821 Ashton Road is lower than the elevation of Ashton Road. Therefore, if the asphalt curb and gutter and associated inlets do not capture the runoff, the overland flow will drain down the driveway at 1821 Ashton Road causing crawl space flooding. Model results indicate that the existing system does not currently convey the 2 -year storm event. Kimberly Drive System The Kimberly Drive System is an open channel system that flows from the Pine Acres subdivision to the Welmar Heights subdivision where it empties into Buckhead Creek. The majority of the system flows through open channels with culvert crossings at Enloe Street, Kimberly Drive, and Ireland Drive. The resident at 2305 Kimberly Drive reported finished floor flooding during rain events. Model results show that each of the three culverts are undersized based on City design standards as the culverts at Enloe Street and Ireland Drive do not convey the 2 -year storm event and the culvert crossing at Kimberly Drive does not convey any storm larger than the 2 -year storm event. Buckhead Creek Watershed Study Page 2 -15 WK Dickson & Co., Inc. SECTION 3 FLOOD MITIGATION ALTERNATIVES 3.1 Buckhead Creek Primary System Developing flood mitigation alternatives in an urban environment is a complex process based on limitations imposed by the constraints within the environment such as floodplain encroachment, increased peak flows due to impervious areas, jurisdictional stream and wetland limits, public and private utilities, and private property. The development of flood mitigation alternatives may not provide the City's desired level of service for new development, but is intended to reduce the frequency and severity of flooding for as many residents of Fayetteville as possible. Flood mitigation alternatives considered for Buckhead Creek include the following: • Infrastructure improvements. • Floodplain storage. • Peak flow attenuation. • Flood protection with levees or floodwalls. • Property acquisition. The projects described below are the recommended alternatives for reducing flooding along Buckhead Creek. Each project has its own individual utility, however to maximize the flood reduction along the stream all of the projects would need to be implemented. Table 3 -1 shows the structures in the watershed with reduced or less frequent lowest adjacent grade (LAG) flooding during the 25 -year storm event. Only those structures that are susceptible to LAG flooding based on model results are included in the table. The proposed improvements resulted in lower water surface elevations for 79 structures during the 25 -year storm event. The level of service improved for 55 of the 79 structures as measured by the storm event that causes LAG flooding changing to a less frequent event when analyzing the 2 -, 10 -, 25 -, and 100 -year storm events. Six structures had increases in their 25 -year water surface elevations due to the proposed culvert improvements at Raeford Road. Additional flood protection measures may be required at these structures to offset the increases in water surface elevations as described later in Section 3. Water surface elevations for existing and proposed conditions along Buckhead Creek are provided in Appendix L The proposed conditions water surface elevations assume each of the projects described below for the Primary System is implemented. In some instances the projects will need to be sequenced as described in Section 9 along with the prioritization of the projects. Buckhead Creek Watershed Study Page 3 -1 WK Dickson & Co., Inc.

Buckhead Creek Watershed Study Page 3 -3 WK Dickson & Co., Inc. SECTION 3 FLOOD MITIGATION ALTERNATIVES 3.1.1 Ferncreek Floodplain Bench and Floodwall The Ferncreek floodplain bench and floodwall is located along Reach 2 of Buckhead Creek between the Buckhead and Windtree subdivisions. The downstream limit of the project is approximately 1,500 feet upstream of the railroad tracks as shown in Figure 3 -1. A floodplain bench includes grading within the floodplain to lower water surface elevations along the length of the project and upstream of the project limits. Grading of the floodplain will only occur above the ordinary high water mark of the stream, so no jurisdictional stream impacts are included in the project. The ordinary high water mark will vary based on the hydrology within the watershed, but can typically be identified as the point along the bank where no woody vegetation is present or is marked by erosion. The ordinary high water mark will need to be included in the final design survey for permitting purposes. Intermittent wetlands are present in the overbank areas and will need to be delineated prior to design. The presence of wetlands may require mitigation for the proposed project if the wetland impacts exceed 0.5 acres. The floodplain bench ranges in width between 100 and 190 feet for approximately 800 feet. The proposed floodwall is located along the right bank with a downstream limit approximately 2,000 feet upstream of the railroad. The length of the proposed floodwall is approximately 1,025 feet. The height of the floodwall ranges between 2.5 and 3 feet high and is intended to protect the properties along the right bank for the 25 -year storm event. The floodplain bench provides water surface reductions during the 25 -year storm event ranging between 0.7 -0.9 feet for eight (8) properties along Ferncreek Drive. The majority of those properties have reported significant yard flooding. Reductions in water surface elevations during the 2 -year storm are as high as 1.8 feet for some of the properties. While the floodplain bench will not eliminate yard flooding for the design storm, the frequency and severity of flooding will be reduced. The bench will also reduce water surface elevations for properties along Briton Circle and Oakfield Court; however the majority of those properties have not reported flooding, likely due to steeper lots, which limits flooding to the very back of the properties. The proposed floodwall provides protection for nine properties along Briton Circle, Oakfield Court, Ferncreek Drive, and Lost Tree Court during the 25 -year storm event. Storms greater than the 25 -year event may overtop the floodwall, which will require appropriate drainage features to be incorporated into the design of the floodwall. While the majority of the project can be constructed within common areas along the stream, portions of the project will require construction on private property. Easements will likely be required for at least eighteen (18) properties. If all of the necessary easements are not obtained, the project may not be feasible or could have less utility than proposed in this report. The total estimated cost for this project is $749,600, which includes potential mitigation costs. Section 8 describes the cost estimates in more detail. Buckhead Creek Watershed Study Page 3 -4 WK Dickson & Co., Inc. SECTION 3 FLOOD MITIGATION ALTERNATIVES 3.1.2 Raeford Road Culvert As noted in Section 2, backwater from Raeford Road during the 25 -year storm extends approximately 3,000 feet upstream of Raeford Road into the Buckhead Creek subdivision. Twenty -eight homes between Raeford Road and the intersection of Ferncreek Drive and Ambrose Place are located within the 25 -year floodplain. The most effective method for reducing water surface elevations upstream of Raeford Road is by installing an additional culvert under Raeford Road as shown in Figure 3 -2. An additional 60" RCP culvert at Raeford Road would reduce water surface elevations during the 25 -year storm between 1.6 and 2.6 feet along the 3,000 foot reach referenced above. Raeford Road is maintained by NCDOT, so extensive coordination with NCDOT would be required to complete the project. Due to the high traffic volume on the road, it is anticipated that tunneling techniques will be required to install the culvert. While the Raeford Road culvert project provides the most overall benefit of any proposed project along Buckhead Creek, the additional culvert would increase peak flows downstream of Raeford Road. Water surface increases along Reach 4 (between Raeford Road and Coventry Road) during the 25 -year storm event range between 0.3 and 0.6 feet. Approximately 1,500 feet upstream of Coventry Road water surface elevations will decrease for the 25 -year storm event if the proposed Coventry Road culvert improvements are constructed as described below. The properties along Reach 4 that would be affected by the increase in water surface elevations are not currently floodprone and do not appear to be floodprone based on the proposed floodplains shown in Figure 3 -3. No additional structural flooding will occur along Reach 4 as a result of these improvements during the 25 -year event. The Coventry Road culvert project lowers water surface elevations approximately 1,500 feet upstream of Coventry Road and 450 feet downstream of Coventry Road. Water surface elevations for the remainder of Reach 5 (between 450 feet downstream of Coventry Road and Lake Francis) increase during the 25 -year storm event. The increase in water surface elevations is not expected to result in significant widening of the 25 -year floodplain as shown in Figure 3 -4. While the increases in water surface are not expected to significantly impact property flooding along Reach 5, two properties along Glenwick Drive and two properties along Village Drive reported flooding during existing conditions in the questionnaire responses. The Devonshire Drive Floodplain Bench and Glenwick Drive Berm and the Roxie Avenue project described below will address flood mitigation alternatives for the properties impacted by the rise in water surface elevations. Immediately upstream of Cumberland Road, water surface elevations for the 25 -year storm event increase by approximately 0.7 feet. The increase in water surface elevation may impact one residential structure along Cumberland Road, although this structure may be abandoned. The City may need to consider providing floodproofing for this structure if the survey and final design indicates the increase in water surface elevations would negatively impact the structure. Buckhead Creek Watershed Study Page 3 -6 WK Dickson & Co., Inc. SECTION 3 FLOOD MITIGATION ALTERNATIVES Prior to completion of the Raeford Road Culvert Project, the City should complete the projects downstream of Raeford Road to reduce or negate the impacts of increasing the conveyance capacity under Raeford Road. Section 9 will address the recommended sequencing of proposed projects. The total estimated cost for this project is $352,700.

North Carolina State Plane NAD 83 Feet SECTION 3 FLOOD MITIGATION ALTERNATIVES 3.1.3 Raeford Road Floodplain Bench As described above increasing the conveyance capacity under Raeford Road provides the most effective way to reduce water surface elevations upstream of Raeford Road. However, the culverts at Raeford Road are actually operating under outlet control for the modeled storm events. When culverts are operating under outlet control, lowering the water surface elevation downstream of a culvert can lower the water surface elevation upstream of a culvert. Installing a floodplain bench downstream of Raeford Road would decrease the 25 -year water surface elevations approximately 1.0 feet upstream of Raeford Road without increasing the conveyance capacity under Raeford Road. To maximize water surface reductions upstream of Raeford Road, the culvert improvement described above would be required. The proposed floodplain bench as shown in Figure 3 -2 ranges in width between 70 and 130 feet and is approximately 600 feet long. While the bench is shown along the left bank, the final configuration may change based on the final survey and design. The proposed bench will likely include significant wetland impacts that may require mitigation and could require moving a sanitary sewer line depending on the limits of the bench determined during design. The total estimated cost for this project is $906,400, which includes an anticipated mitigation fee. Mitigation fees are described in more detail in Section 6. Buckhead Creek Watershed Study Page 3 -1 1 WK Dickson & Co., Inc. SECTION 3 FLOOD MITIGATION ALTERNATIVES 3.1.4 Coventry Road Culvert and Floodplain Bench Coventry Road currently overtops during the 10 -year storm event. This project includes installing 2 - 8' x 6' box culverts along the left bank looking downstream as shown in Figure 3 -4. The existing culverts are in good condition and can remain in place. Installing the two additional box culverts will provide a 25 -year level of service for Coventry Road and reduce water surface elevations for the 25 -year storm upstream of Coventry Road between 1.0 feet and 2.8 feet. Five (5) houses upstream of Coventry Road are currently located in the existing conditions 25 -year floodplain. The proposed culvert improvements will remove four (4) of the five (5) houses from the 25 -year floodplain. Three (3) of the houses will be outside of the 100 -year floodplain for proposed conditions. The proposed culvert will significantly reduce flooding upstream of Coventry Road, however additional improvements are required to reduce flooding downstream of Coventry Road. The culvert improvement project will include a floodplain bench on the left bank for approximately 400 feet downstream of Coventry Road. Based on field inspection, minimal wetland impacts are anticipated for construction of the bench. The bench ranges in width between 40 and 70 feet and is located on City -owned property. An 18" RCP sanitary pipe is located within the limits of the floodplain bench. The bench can likely be constructed without impacting the sanitary pipe since the excavation shall occur above the sanitary pipe. However, the existing sanitary manholes will likely need to be replaced and retrofitted with watertight covers. The City should also consider a video inspection of the sanitary pipe to determine the condition of the pipe prior to construction. Concrete sanitary pipes can be susceptible to corrosion due to the hydrogen sulfide gases. Based on the video inspection, the sanitary pipe may need to be lined or replaced. The floodplain bench reduces the 25 -year water surface elevation downstream of Coventry Road by approximately 1.0 feet. The combination of the culvert improvement and the floodplain bench would improve the level of service for the residents at 4501 Coventry Road from a 2- to 10 -year level of service. An earthen berm along the right bank approximately 1 to 1.5 feet high, in addition to the improvements described above would provide a 25 -year level of service for the home at 4501 Coventry Road. The total estimated cost for this project is $866,100. Should the sanitary pipe along the left bank of Buckhead Creek require rehabilitation or replacement, the preliminary cost estimate would increase. Buckhead Creek Watershed Study Page 3 -12 WK Dickson & Co., Inc. SECTION 3 FLOOD MITIGATION ALTERNATIVES 3.1.5 Devonshire Drive Floodplain Bench and Glenwick Drive Berm As described above, the proposed culvert at Raeford Road would increase water surface elevations along Reach 5. The Devonshire Drive floodplain bench would minimize the impacts on water surface elevations immediately downstream of Coventry Road from the increased culvert capacity at Raeford Road. The bench would range between 40 and 75 feet wide and would be located along the right bank for 770 feet. Water surface elevations for the 25 -year storm would decrease for 450 feet downstream of Coventry Road. Beyond that point, elevations would increase by approximately 0.5 feet during the 25 -year storm for 0.5 miles downstream. While no structures are anticipated to be at increased risk of flooding along the 0.5 mile stretch, several residences along Glenwick Drive currently experience significant yard flooding. To protect those properties during the 25 -year event, a 2 -foot high earthen berm is proposed along the left bank as shown in Figure 3 -4. Construction of both the bench and berm may impact wetlands, which could require mitigation, pending a detailed wetland delineation. The total estimated cost for this project including estimated mitigation fees is $421,400. Buckhead Creek Watershed Study Page 3 -13 WK Dickson & Co., Inc. SECTION 3 FLOOD MITIGATION ALTERNATIVES 3.1.6 Lake Francis Wetland Enhancement/Restoration Three of the five projects recommended along Buckhead Creek may cause significant wetland impacts. Estimated mitigation costs are included in the total project costs for the Raeford Road floodplain bench and the Devonshire Drive floodplain bench and Glenwick Drive berm assuming 2009 fee in lieu rates which are $59,600 per riparian wetland mitigation unit (WMU) for impacts in this watershed. Mitigation costs established for the Ferncreek floodplain bench and floodwall assume that 25% of the area of the proposed project will impact wetlands, as the wetlands are more isolated and intermittent in this area. A detailed wetland delineation will be required to finalize the amount of impacts for each project. The Army Corps requires a 2:1 ratio of credits to impacts; therefore for every acre of wetland impacted a fee of $119,200 would be required to purchase mitigation credit. One alternative to paying for mitigation is to complete onsite mitigation in the watershed. Removing the dam at Lake Francis would provide an opportunity for wetland and stream enhancement/restoration that could provide the necessary credits for the expected impacts. The dam is currently breached; however a 9 -acre body of open water remains as shown in Figure 3 -5. By removing the dam and potentially downstream beaver dams, the water level in the open body of water could be lowered to a level where wetland plantings and a stream channel could be established. The mitigation project could provide enough credits to offset the impacts incurred by the projects described above; however the United States Army Corps of Engineers (USACE) and Division of Water Quality (DWQ) would have final determination on the number of credits provided by the project. Excess mitigation credits could be applied to future City projects. The proposed project would have to be monitored for five (5) years after construction to complete the mitigation process. The total estimated cost for design, construction, and monitoring of this project is $423,400. Buckhead Creek Watershed Study Page 3 -14 WK Dickson & Co., Inc. 44W.5 joog !MSM "MANW24 4 723 4308 - 0 � m SECTION 3 FLOOD MITIGATION ALTERNATIVES 3.2 Buckhead Creek Secondary Systems Developing flood mitigation alternatives for the secondary systems typically included increases in pipe capacity and /or rerouting flows where more space was available for improvements. In general the proposed improvements for the secondary system are less complex from a permitting perspective. However, the proposed improvements for the secondary system are oftentimes constrained by private property as space is typically limited between houses or other structures. The projects described below are the recommended alternatives for each of the secondary systems. In some instances, the full benefit of the proposed improvements may not be realized unless the proposed primary system improvements along Buckhead Creek are completed since several of the secondary systems are affected by backwater from Buckhead Creek. Section 9 will discuss prioritization and project sequencing in detail. 3.2.1 Buckhead Kingsford System WK Dickson recommends the following improvements for the Buckhead Kingsford System as shown in Figure 3 -6: Murray_ Hill Lane • Install 105 linear feet of 15" RCP between 805 Murray Hill Road and 809 Murray Hill Road. • Install 2 inlets. Levenhall Drive • Remove 179 linear feet of 30" RCP and install 179 linear feet of 42" RCP between 604 Levenhall Drive and 608 Levenhall Drive. • Remove 116 linear feet of 24" RCP and install 116 linear feet of 42" RCP along Levenhall Drive. • Remove 143 linear feet of 24" RCP and install 143 linear feet of 36" RCP along Levenhall Drive. • Remove 43 linear feet of 24" RCP and install 43 linear feet of 36" RCP along Levenhall Drive. • Remove 155 linear feet of 24" RCP and install 155 linear feet of 36" RCP along Levenhall Drive. • Install 175 linear feet of 30" RCP along Harlow Drive. • Install 210 linear feet of 18" RCP along Harlow Drive. • Install 290 linear feet of 18" RCP along Graylyn Place. • Install 245 linear feet of 18" RCP between 519 Harlow Drive and 540 Levenhall Drive • Replace 33 linear feet of 15" RCP along Graylyn Place. • Remove 79 linear feet of 15" RCP and install 79 linear feet of 24" RCP under Raeburn Court. Buckhead Creek Watershed Study Page 3 -16 WK Dickson & Co., Inc. SECTION 3 FLOOD MITIGATION ALTERNATIVES • Install 11 inlets. • Replace 1 headwall. Ferncreek Drive • Install 258 linear feet of 4'x8' RCBC behind 610 Longwood Place. • Remove 120 linear feet of 54" RCP and install 120 linear feet of 4'x8' RCBC along 610 Longwood Place. • Remove 184 linear feet of 54" RCP and install 184 linear feet of 4'x8' RCBC between 4235 Ferncreek Drive and 4239 Ferncreek Drive. • Remove 13 linear feet of 54" RCP and install 13 linear feet of 4'x8' RCBC under Ferncreek Drive. • Remove 177 linear feet of 54" RCP and install 177 linear feet of 4'x6' RCBC along Ferncreek Drive. • Install 2 custom inlets. • Install 3 new custom junction boxes. • Replace 1 headwall. The proposed improvements for the Buckhead Kingsford System address flooding concerns in three (3) predominant areas: along Murray Hill Road, Levenhall Drive, and Ferncreek Drive. Flooding adjacent to Murray Hill Road is located along the backyards of 805 and 809 Murray Hill Road. The proposed 15" RCP will collect runoff from the back of the properties and convey it to the street, connecting to the existing drainage system. The proposed improvement provides a 10 -year level of service. The proposed improvements along Levenhall Drive and Harlow Drive will provide a 10 -year level of service for the majority of the area, with the exception of some continued yard flooding behind 536 Levenhall Drive. Flooding in this area will be reduced with these improvements; however the only way to achieve a 10 -year level of service would be to install additional pipes under the All American Expressway, which was not considered cost effective. Due to limited space between houses along Graylyn Place, runoff along Graylyn Place was piped to Harlow Drive and then southeast to Levenhall Drive. The flooding along Ferncreek Drive is partially due to an undersized drainage system and partially due to backwater from Buckhead Creek. The proposed improvements will provide a 10 -year level of service along Ferncreek Drive, Milden Road, and Longwood Drive regardless of whether improvements are completed along Buckhead Creek. However, significant flooding may still occur for several properties along Ferncreek Drive and Humboldt Place during the 10 -year storm event unless the culvert improvements at Raeford Road are completed. The proposed box culvert between 605 Humbolt Place and 610 Longwood Place may require stream mitigation pending a jurisdictional determination by the Army Corps of Engineers. Stream mitigation will increase the overall cost of the project. A floodplain bench could be installed instead of a box culvert at this location; however a significant portion of the adjacent yards would be impacted and likely be opposed by the homeowners.

SECTION 3 FLOOD MITIGATION ALTERNATIVES 3.2.2 Broyhill Road System WK Dickson recommends the following improvements for the Broyhill Road System as shown in Figure 3 -7: • Remove 203 linear feet of 24" RCP and install 203 linear feet of 36" RCP between 4321 Ferncreek Drive and 4325 Ferncreek Drive. • Remove 50 linear feet of 24" RCP and install 50 linear feet of 36" RCP under Ferncreek Drive. • Remove 33 linear feet of 18" RCP and install 33 linear feet of 24" RCP under Broyhill Road. • Install 27 linear feet of 15" RCP under Broyhill Road. • Install 3 inlets. • Install 1 manhol eJ unction box. • Replace 1 existing headwall at outlet. The proposed improvements will provide a 10 -year level of service for the intersection at Broyhill Road and Ferncreek Drive if the improvements to the culvert at Raeford Road along Buckhead Creek are completed as well. If the improvements along Buckhead Creek are not completed, backwater from the creek will likely continue to cause flooding along Ferncreek Drive. The additional inlets at the intersection of Broyhill Road and Ferncreek Drive will provide additional capture for any runoff along Broyhill Road that is not conveyed in the drainage system as the system along Broyhill will not meet a 10 -year level of service. The total estimated cost for this project is $163,800. Buckhead Creek Watershed Study Page 3 -20 WK Dickson & Co., Inc.

The proposed improvements will provide a 10 -year level of service for the Ferncreek Norwood System. While backwater from Buckhead Creek will cause flooding along the backyards of 4365 Ferncreek Drive and 4361 Ferncreek Drive, the proposed improvements will meet the intended level of service regardless of whether the proposed improvements along Buckhead Creek are completed. The proposed 18" RCP will need to pass above an existing sanitary sewer line, but there does not appear to be a conflict based on the elevations provided in the City's GIS sanitary sewer data. The total estimated cost for this project is $107,000.

The proposed improvements provide a 10 -year level of service for the Westwood System. Runoff is rerouted along Palomar Street and Rushmore Drive to avoid pipe replacements along private property in close proximity to houses. Replacing pipes in the same location as the existing system would also require the removal of several large hardwood trees. Flooding will likely still occur in the vicinity of the culvert under All American Expressway for several properties along Rainier Drive. Costly culvert improvements under the All American Expressway would be the only solution for reducing the frequency of the yard flooding, but are considered cost prohibitive. The total estimated cost for this project is $672,900.

'� Coordinate System: North Carolina State Plane NAD 83 Feet SECTION 3 FLOOD MITIGATION ALTERNATIVES 3.2.5 Raeford Faison System WK Dickson recommends the following improvements for the Raeford Faison System as shown in Figure 3 -10: • Remove 43 linear feet of 18" RCP and install 43 linear feet of 30" RCP behind 212 Faison Avenue. • Install 301 linear feet of 30" RCP behind properties along Faison Avenue. • Install 205 linear feet of 30" RCP running from Faison Avenue to the northwest corner of 200 Faison Avenue. • Remove 179 linear feet of 15" RCP and install 179 linear feet of 24" RCP along Faison Avenue. • Remove 222 linear feet of 15" RCP and install 222 linear feet of RCP along Faison Avenue • Install 3 inlets. • Install 3 junction boxes. As noted in Section 2, the likely cause of flooding along Faison Avenue is backwater from the pipe system along Raeford Road that ultimately drains into Buckhead Creek. Providing a 10- year level of service along Faison Avenue using the existing horizontal alignment for the conveyance system would require replacing approximately 2,000 feet of pipe along Raeford Road which would be costly and interrupt traffic along a major thoroughfare for a significant period of time. Therefore, the proposed improvements reroute the drainage south along Faison Avenue to an existing drainage network that flows west towards Ireland Drive. Based on field survey, the system between Faison Avenue and Ireland Drive appears to consist of 60" RCP, however in some areas the pipe size could not be verified due to inaccessible manholes. Prior to final design, the pipe sizes and conditions will need to be verified through video inspection. The proposed improvements that provide a 10 -year level of service assume that the pipes between Faison Avenue and Ireland Drive are 60" RCP. The total estimated cost for this project is $260,400.

The proposed improvements will provide a 10 -year level of service along Wellington Drive, Montclair Road, and Stoneykirk Drive and a 2 -year level of service along Belford Road. Increasing the size of the pipes at the downstream end significantly reduce the water surface elevations throughout the system. Providing a 10 -year level of service along Belford Road would require replacing the entire drainage system along Belford Road which would cause significant impacts and traffic delays to the residents. Should significant flooding continue along Belford Road after the downstream improvements have been installed, the City may want to reevaluate proposed improvements along Belford Road. The proposed pipe between 841 Stoneykirk Drive and 845 Stoneykirk Drive will need to be constructed in a limited corridor and may require additional costs to protect the foundation of the adjacent houses. The total estimated cost for this project is $330,700. Buckhead Creek Watershed Study Page 3 -28 WK Dickson & Co., Inc.

If the Coventry Road culvert is not installed, Odom Drive will continue to flood regardless of any improvements to the secondary systems. The outfall pipe east of Odom Drive across from Redwood Drive is currently damaged and should be replaced by maintenance crews, but is not likely contributing to flooding. No additional improvements are recommended for this system. 3.2.8 Coventry System WK Dickson recommends the following improvements for the Coventry System as shown in Figure 3 -12: • Remove 181 linear feet of 24" RCP and install 181 linear feet of 36" RCP between 4314 Coventry Road and 4318 Coventry Road. • Replace 1 existing inlet. • Remove existing headwall and install new headwall at outlet. The proposed improvements provide a 10 -year level of service for the Coventry System. The project may cause significant impacts to private property including landscaping and storage buildings in the backyards of the two properties. Alternatively, drainage could be conveyed southwest along Coventry Road and discharge directly to Buckhead Creek, however this alternative would have a significantly higher cost. The total estimated cost for the recommended alternative is $89,400. Buckhead Creek Watershed Study Page 3 -30 WK Dickson & Co., Inc.

The proposed improvements for the Roxie Avenue System address flooding concerns in four (4) predominant areas: Faison Avenue, Roxie Avenue, Martindale Drive, and Brentwood Drive. Faison Avenue north of Crestwood Street currently has no conveyance system to collect runoff. The intent of the original design appears to have runoff drain either to Rodie Avenue or Hicks Avenue; however the relatively flat topography causes standing water along Faison Avenue. The proposed improvements include a new pipe system along Faison Avenue from Buckhead Creek Watershed Study Page 3 -33 WK Dickson & Co., Inc. SECTION 3 FLOOD MITIGATION ALTERNATIVES Hanna Street south to the existing conveyance system along Faison Avenue. Portions of the existing system along Faison Avenue will need to be increased in size to provide a 10 -year level of service. Flooding along Roxie Avenue will be alleviated by installing a now splitter near the intersection of Martindale Drive and Roxie Avenue and a conveyance system along Martindale Drive. The proposed pipes along Martindale Drive will allow storm flows to bypass Roxie Avenue and connect back to the existing conveyance system near the intersection of Martindale Drive and Hartwell Road. Reducing the storm flows along Roxie Avenue will provide a 10 -year level of service without disturbing a significant portion of Roxie Avenue. Installing the new infrastructure along Martindale Drive may result in utility conflicts. A detailed subsurface survey will be required along Martindale Drive prior to design. The existing conveyance system along Martindale Drive south of Hartwell Road will need to be increased in size to convey the additional flow from the new system along Martindale Drive. Flooding along Village Drive near the intersection with Brentwood Road is likely caused by limited inlet capacity. The proposed improvements include additional inlets and connector pipes along Village Drive to increase the overall inlet capacity of the system. If flooding persists after adding inlets, the City may need to consider increasing the size of the pipe between 3942 Village Drive and 4002 Village Drive. Two residences (4140 Village Drive and 4144 Village Drive) near the confluence of the Roxie Avenue tributary and Buckhead Creek reported finished floor and crawl space flooding in the questionnaires. The two residences are located on the left bank and multi - family homes are located on the right bank. There is no available space for floodplain benches and a floodwall or levee would likely increase the flood risk for the adjacent property owners. Therefore, infrastructure improvements will not be effective in mitigating the flood risk for the two residences along Village Drive. Other flood mitigation options include structure elevation or property acquisition. Structure elevation will not prevent yard flooding, but can keep the finished floor from flooding. Based on the Cumberland County parcel records the combined tax value of the two residences is $129,900. If the property owners are willing, the City could consider purchasing the properties to remove the flood risk. The total estimated cost for the Roxie Avenue System improvements is $3,089,700 which does not include structure elevation or property acquisition for the residences along Village Drive.

The proposed improvements will provide a 10 -year level of service along Ashton Road and a 5 -year level of service along Ramblewood Drive. The 30" RCP between 4600 Ramblewood Drive and 1932 Ashton Road remains undersized to convey the 10 -year storm event; however replacing this pipe would be very intrusive for the adjacent property owners to the proximity of a house and garage to the pipe. Those property owners also have not reported flooding concerns, so at this time the City should monitor flooding to determine if additional improvements are needed. The larger outlet pipe and the additional inlets on Ashton Road will alleviate the majority of the flooding concerns along Ashton Road and capture additional runoff from Ramblewood Drive if needed. The total estimated cost for this project is $261,000. Buckhead Creek Watershed Study Page 3 -37 WK Dickson & Co., Inc.

The proposed improvements will provide a 10 -year level of service for the Ashton Road Friar Avenue System. A new drainage system will be installed along Park Knoll Lane east to Lake Francis. The outfall will be constructed within the City's property and outside of the jurisdictional wetlands. A flow splitter will be installed near the intersection of Friar Avenue and Ashton Road to convey a portion of the watershed's drainage along Park Knoll Lane and the remainder of the drainage through the existing system. Increasing the size of the pipes within the existing system using the same horizontal alignment would be very difficult due to private property constraints and the proximity of the houses to each other. The total estimated cost for this project is $567,300.

Coordinate System: North Carolina State Plane NAD 83 Feet SECTION 4 WATER QUALITY RETROFITS Traditional stormwater management has typically been designed to reduce flooding, but at times has neglected water quality by collecting runoff directly from impervious surfaces into a closed drainage system. Runoff from impervious areas collects high concentrations of pollutants and nutrients that if left untreated can cause negative impacts to water quality in the receiving waters. Negative impacts may include less biodiversity, hazards to the health of fish and wildlife, as well as human health hazards. Many communities in North Carolina now require some form of water quality treatment for new development; however existing developments typically have little or no water quality treatment. Best management practices (BMPs) can be constructed to treat runoff prior to being discharged to the stormwater conveyance system and ultimately the receiving waters of the system. Retrofitting BMPs can be difficult due to limited space and other constraints. BMP retrofits identified in the Buckhead Creek watershed are described below. 4.1 Best Management Practices (BMPs) Alternatives Considered Stormwater BMPs were evaluated and sized for pollutant removal performance in the Buckhead Creek watershed using in -house spreadsheets based on current design requirements found in the North Carolina Department of Environment and Natural Resources (NCDENR) design manual titled, "Stormwater Best Management Practices Manual" dated July 2007. BMP types considered for this effort are described below. Due to the nature of the well - draining soils, available drainage areas, and the presence of residential homes, the majority of the recommended BMPs are bioretention ponds, grass swales, and infiltration basins. Wet Detention Basins - Also called "detention ponds" or "wet ponds," these facilities are designed to detain stormwater in order to attenuate flooding and allow time for solids to settle out of the water column. Wet ponds also allow for biological uptake of some pollutants by plants installed around the perimeter of the basin, bacteria in the water, and algae (DWQ, 2005). This type of BMP offers high pollutant removal efficiencies and is useful in treating stormwater from large drainage areas ( >10 acres). Stormwater Wetlands - These facilities are similar to wet detention basins but are designed to provide additional stormwater treatment through the mechanisms similar to natural wetlands. These facilities are effective at removing suspended solids, nutrients, metals, organics, petroleum compounds, and potentially pathogenic microorganisms through physical, chemical, and biological processes (DWQ, 2005). Wetlands are more efficient at removing certain types of pollutants than wet ponds (Center for Watershed Protection, 2000; Hunt and Doll, 2000). Stormwater wetlands improve water quality, provide flood control, enhance wildlife habitat, and may provide unique educational opportunities among other functions. However, a high water table or soils with very low permeability are required for proper function of stormwater wetlands. Bioretention - These stormwater treatment cells are designed to drain well and look like part of the developed landscape (Hunt and White, 2001). Therefore, they may be an aesthetic amenity to landscaping schemes. Bioretention cells, or "rain gardens," function best when treating small, highly impervious drainage areas such as parking lots (DWQ, 2005). Buckhead Creek Watershed Study Page 4 -1 WK Dickson & Co., Inc. SECTION 4 WATER QUALITY RETROFITS Bioretention removes pollutants through mechanisms that stormwater wetlands also employ, and allow water to infiltrate into the soil and recharge groundwater (Hunt and White, 2001). They also provide limited peak flow attenuation to reduce flooding. They perform well in areas where groundwater is several feet below the ground surface. Infiltration Basins - Infiltration basins are desirable BMPs because of the associated pollutant removal efficiencies and the additional benefit of groundwater recharge (i.e. reducing the hydrologic effects of impervious surfaces). Because of the excellent hydrologic characteristics of the soils in the watershed, infiltration basins are a cost effective BMP option in the Fayetteville area. These dry basins do not maintain a permanent pool like a wet pond and do not have an outlet device. They are designed to hold water until it infiltrates into the soil or evaporates. This type of BMP reduces runoff, improves local hydrology through groundwater recharge, and removes sediment and associated pollutants (DWQ, 2005). These devices should be situated in small drainage areas ( <5 acres) where groundwater is relatively deep. Infiltration basins require more cleaning maintenance than most other types of BMPs. Grass Swales - These grass lined open channels are often used as part of a treatment system along with other BMPs. They are commonly used to replace storm sewers (DWQ, 2005). They remove pollutants by filtration and settling processes and allow some stormwater to infiltrate into the soil. They are especially effective at removing suspended sediment and associated pollutants. 4.2 BMP Pollutant Removal Efficiencies Pollutant removal efficiencies for the different types of BMPs vary and there are many sources of removal efficiency data. One such source referenced from the U.S. Environmental Protection Agency's Stormwater Best Management Practices Design Guide (EPA, 2004) is shown in Table 4 -1 below. There is no single source that can be cited to illustrate differences in pollutant removal efficiencies between different types of BMPs for all cases. BMP function is related to site specific conditions, types and concentrations of pollutants in runoff, and design features of the system.

Twenty -five (25) potential BMP locations were initially identified. These locations were field visited by WK Dickson staff in March 2009 to determine the feasibility of each site for a BMP. An overview map has been provided showing these sites (see Figure 4 -1). The proposed locations for the BMPs were evaluated based on the following criteria: • Watershed Size / Drainage Area — Larger watershed sizes allow an opportunity for more treatment. A significant contributing drainage area would allow the use of a larger, more regional BMP such as a wet pond or extended detention wetland. • Percentage of impervious area — Areas with high impervious percentages allow an opportunity for more treatment. • Proximity to existing conveyance system — Runoff will need to be diverted into the BMP and then discharged back to the conveyance system. Locations in close proximity to the existing conveyance system will reduce the cost associated with constructing new drainage structures. • Land Availability /Ownership — The proposed BMPs will require undeveloped land. Publicly owned land was identified because the high cost of private land can make a project unlikely. • Topography — Sufficient vertical relief, up to 5 feet, is required to allow certain BMPs (i.e., bioretention and wet ponds) to function per NCDENR design requirements. • Hydrologic conditions — BMPs such as wet ponds or extended detention wetlands need the proper hydrologic conditions for plants to survive. The soils or existing water table must allow for the BMP facility to permanently hold stormwater runoff. There were several public schools located in the Buckhead Creek watershed. These schools were closely looked at due to the large impervious areas available for treatment and for the Buckhead Creek Watershed Study Page 4 -3 WK Dickson & Co., Inc. SECTION 4 WATER QUALITY RETROFITS educational benefits of installing a BMP onsite. Additionally, sites that had existing flooding problems were also closely evaluated for water quality retrofit opportunities. Several of the sites identified met multiple criteria for a successful project and were therefore recommended in this master plan. 4.4 Recommended BMPs Based on the field visits and the above criteria, eight (8) sites were recommended for BMP retrofits. Factors that eliminated a site from consideration included the following: limited space, tree density, utility conflicts (i.e. high voltage transformers and other electrical distribution equipment), insufficient topographic relief, private property, and anticipated public opposition from private residential homeowners. Preliminary conceptual design calculations were completed for each of the eight (8) BMPs (see Appendix L). The design calculations were based on methodologies found in the North Carolina Department of Environment and Natural Resources ( NCDENR) Stormwater BMP Manual. The size of the BMP is based on the contributing watershed area and the amount of impervious area within the watershed. Per NCDENR requirements, the recommended BMPs were designed to treat runoff from the first one -inch of rainfall. The treatment volume is directly correlated to the amount of impervious area. Watersheds with larger amounts of impervious area convert more of the rainfall into runoff, thereby requiring a larger sized BMP. Buckhead Creek Watershed Study Page 4 -4 WK Dickson & Co., Inc. SECTION 4 WATER QUALITY RETROFITS 4.4.1 Water Quality Project #1: Mary McArthur Elementary School — Bioretention Pond The front of Mary McArthur Elementary School is an ideal location for retrofitting a bioretention pond. The school has a roof and large parking lot that are currently draining directly into roadside curb and gutter and eventually into the existing closed system located at the intersection of Village Drive and Ireland Drive. Due to the large drainage area and relatively steep slopes of the road, it is likely that this roadway intersection is flooding during significant rainfall events. Consequently, this project will have both water quality and flood reduction benefits. The required surface area for the proposed bioretention pond is approximately 1,500 square feet (0.03 acres). A concept level plan of the proposed improvements is shown in Figure 4 -2. The proposed Mary McArthur Elementary School bioretention project consists of the following improvements: • Install a bioretention pond designed to treat runoff from the adjacent parking lot and runoff from redirected roof leaders. The proposed impervious areas draining to the proposed pond is 0.15 acres. • Install a grass swale directing flow from the back of the school parking lot into the proposed bioretention pond. The proposed grass swale will serve as pre- treatment for the runoff prior to reaching the bioretention pond. • Install a concrete curb cut that allows water to access the proposed grass swale and BMP. • Install a yard inlet with an 18" outfall pipe directing flow into the existing drainage system located at the intersection of Village Drive and Ireland Drive. The estimated construction cost for the bioretention pond facility at Mary McArthur Elementary School is $54,000. Buckhead Creek Watershed Study Page 4 -6 WK Dickson & Co., Inc.

There is a large, rectangular grass area shown in Exhibit 4 -1 that could be used to treat the runoff from the 0.3 -acre parking lot. The swale would be approximately 200 feet where runoff would infiltrate into the ground and overflow would enter the existing drainage structures. The top width of the swale would be at least 25 feet and the depth of ponding would not exceed 12 inches. The proposed BMP would discharge treated water into the existing open channel. A concept level plan of the proposed improvements is shown in Figure 4 -3. The proposed water quality project consists of the following improvements: • Modify existing grass swale designed to allow curb cuts to function as designed. • Modify existing curb cuts that allow water to access the proposed grass swale and BMP. The existing curb cuts are not functioning as designed. The estimated construction cost for the engineered water quality grass swale at the Mary McArthur Elementary School is $16,300 . Exhibit 4 -1.

The proposed project site (shown in Exhibit 4 -2) will treat runoff from this parking lot along with runoff from redirected roof leaders prior to discharging into the existing closed system. The required surface area for the proposed bioretention pond is 21,100 square feet (0.48 acres). A concept level plan of the proposed improvements is shown in Figure 4 -4. The proposed Douglas Byrd High School water quality project consists of the following improvements: • Install a bioretention pond designed to treat runoff from the adjacent parking lot and runoff from redirected roof leaders. The impervious areas draining to the proposed pond is approximately 2.7- acres. This is the largest area identified for treatment in the Buckhead Creek watershed project area. • Install a grass swale directing flow from the back of the school parking lot into the proposed bioretention pond. The proposed grass swale will serve as pre - treatment for the runoff prior to reaching the bioretention pond. • Install concrete curb cuts that allow water to access the proposed grass swale and BMP. • Install a yard inlet with an outfall barrel directed into the existing drainage system. The proposed project at Douglas Byrd High School is one of the best retrofit opportunities because of the large potential treatment area. Additionally, the installation of the BMP on the school's property could provide learning opportunities and educational benefits to the students. The estimated construction cost for the bioretention pond facility at Douglas Byrd High School is $171,900 . Exhibit 4 -2.

The parking lot in the rear of the school floods to depths as high as nine inches when the grate is not properly cleaned. Additionally, the existing parking lot is undersized, causing a parking problem. Visitors and employees of the school are forced to park in the woods adjacent to the school along the entrance road. The proposed project identified behind the school would provide the desired water quality benefits while also alleviating the existing flooding and parking problems. A concept level plan of the proposed improvements is shown in Figure 4 -5. The required surface area for this pond to adequately treat the first flush is approximately 6,600 square feet (0.15 acres). The proposed Douglas Byrd Middle School BMP retrofit project consists of the following improvements: • Install a bioretention pond designed to treat runoff from the proposed and existing adjacent parking lots. • Install two new catch basin inlets to accept surface runoff from behind the proposed parking lot. • Install two concrete curb cuts that will allow water to access the proposed catch basins located in the new parking lot. These curb cuts will reduce the potential for future flooding in the existing parking lot by reducing maintenance issues caused by debris clogging the existing grate inlet. • Install a grass swale that directs flow off the back of the existing school parking lot into the proposed bioretention pond. The proposed grass swale will serve as pre- treatment for the runoff prior to reaching the bioretention pond. • Install a yard inlet with outfall barrel directing flow into the existing drainage system. The estimated construction cost for the bioretention pond facility at Douglas Byrd Middle School is $107,800 . It should be noted that this estimate does not include the construction costs necessary to install the proposed parking lot.

The flooding is occurring due to a lack of positive drainage and is causing approximately a 7 -foot spread onto Ireland Drive. This presents a safety issue with cars abruptly breaking or driving into the lane of oncoming traffic to avoid hitting the ponded stormwater runoff. An opportunity exists at the intersection to retrofit a BMW into the vacant lot located adjacent to the area of flooding. A concept level plan of the proposed improvements is shown in Figure 4 -6. The proposed Sandra Drive and Ireland Drive BMP retrofit project consists of the following improvements: Install a grass infiltration basin designed to maximize storage potential and reduce flooding. This basin will not be designed per NCDENR design requirements due to the adjacent concrete lined open channel. However, some water quality benefits will still be achieved. Install two grass swales directing flow off Ireland Drive into the infiltration basin. The proposed grass swales will serve as pre- treatment for the runoff prior to reaching the infiltration basin. Install two concrete flumes that will prevent grass from obstructing stormwater runoff from leaving the roadway entering the grassed vacant lot. Install a level spreader to evenly direct flow toward the concrete open channel. A level spreader is proposed here to avoid having to bore a closed pipe through the concrete bank of the open channel.

The open space would be a good location for a grass infiltration basin or bioretention pond that treats stormwater runoff from the roof of the school and possibly the parking lot located off of Ireland Drive. A concept level plan of the proposed improvements is shown in Figure 4 -7. The proposed Ireland Drive Elementary School BMP retrofit project consists of the following improvements: • Install a shallow grass infiltration basin or a bioretention pond designed to treat stormwater runoff from the school's roof. While the BMP will not be able to treat the entire drainage area to the recommended level per NCDENR design requirements, there will be some water quality benefits achieved. • Install two grass swales directing flow from the outfall of the roof leaders into the BMP facility. The proposed grass swales will serve as pre- treatment for the runoff prior to reaching the infiltration basin. • Install a yard inlet with an outfall barrel directing flow into the existing drainage system located at the unnamed access road. Exhibit 4 -4. Open space in front of Ireland Drive Elementary School The estimated construction cost is $47,900 for the bioretention pond option and $27,800 for the grass infiltration basin. The proposed BMP would provide an educational benefit to the project which could also help to obtain funding and offset project costs. Prior to determining the type of BMP to install, it is recommended that a representative for the school be contacted and involved in the decision - making process.

Owen Elementary School — Bioretention Pond William H. Owen Elementary School is providing a great example of the use of grass swales to provide infiltration benefits to the stormwater runoff prior to entering a closed drainage system. Throughout the school, there are numerous grass swales that collect stormwater runoff and direct this flow to a drainage inlet located a significant distance from the impervious areas of the school. These grass swales are flat and have very level side slopes. There are little to no signs of erosion. A parking lot recently constructed behind the school was designed to use curb cuts and an open grass swale similar to the rest of the school's drainage systems. However, the existing curb cuts are obstructed with grass and other vegetation and are not performing as designed. The proposed improvements for the William H. Owen Elementary School would entail the following: • Install concrete flumes at the existing curb cuts. They should be set at an elevation that is several inches lower than the adjacent asphalt curb cut to prevent grass from obstructing stormwater runoff from accessing the existing grass swale. The estimated construction cost for the proposed concrete flume is $13,800 . There is also the option of adding an educational BMP near the school in conjunction with the above improvement. The proposed facility would discharge treated water into the existing drop inlet located adjacent to the parking lot and Scotland Drive. This option further improves the existing drainage system and also takes advantage of the educational benefit of installing a BMP on the school's property. A concept level plan of the proposed improvements is shown in Figure 4 -8. This option would involve the following: • Install a shallow bioretention pond designed to treat stormwater runoff from the impervious parking lot. While the BMP will not be able to treat the area to the recommended level per NCDENR design requirements, there will be some water quality benefits achieved. The estimated construction cost is $46,300 for the bioretention pond. Buckhead Creek Watershed Study Page 4 -18 WK Dickson & Co., Inc.

A concept level plan of the proposed improvements is shown in Figure 4 -9. The proposed Ashton Road BMP retrofit project consists of the following improvements: • Retrofit the existing, abandoned pond. • Install a flow diversion structure along Aston Road to divert the first flush of runoff into the wetland for storm water treatment. • Install a riser structure with a 24" outfall barrel directing flow from the BMP into the existing drainage ditch that the existing system at Ashton Road currently drains to. • Remove trees off the existing dam embankment. • Install 30" RCP that will divert flow from large flood events around the BMP facility. • Install manhole. The estimated construction cost for the extended detention wetland facility on Ashton Road is $114,500. AVMF: Exhibit 4 -5.

Owen Elementary School as shown in Exhibit 4 -6. The total area of the parcel is approximately 16 acres. It is recommended that when this site is eventually developed that the developer be strongly encouraged to incorporate BMWs at this location to maintain the pre - project conditions. If this requirement is cost - prohibitive or considered excessive then a cost share option with the City should be explored to help reduce costs to the developer. Exhibit 4 -6. Abandoned asphalt lot across from William H. Owen Elementary School Buckhead Creek Watershed Study Page 4 -22 WK Dickson & Co., Inc. SECTION 5 PUBLIC EDUCATION AND OUTREACH Successful implementation of the Buckhead Creek Watershed Study and stormwater management as a whole requires extensive public education and outreach. The City has taken important steps in public outreach within the Buckhead Creek watershed through the use of direct mail questionnaires, web -based applications, and public meetings. Questionnaires were mailed to residents throughout the watershed in September of 2008 requesting feedback on floodprone areas, and any water quality concerns. A web -based application linked to the City's website was also available to residents for completing the questionnaires. Compiled results of the questionnaires can be found in Appendix D. In addition to the questionnaires, City staff held a public meeting in September of 2008 to introduce the project and facilitate further feedback from the public. A follow -up meeting will be held in May of 2009 to share results of the Study with the public. The initial public feedback is critical to identifying floodprone areas and validating model results. As selected projects proceed into design and construction continuous public outreach will be critical to the success of the projects. Most of the proposed improvements include some impacts to private properties which will require permanent drainage easements and temporary construction easements. Public meetings and individual property owner meetings through the design process will help educate property owners on the benefits of the proposed projects and the temporary and permanent impacts from construction. In addition to the public education and outreach completed for projects specific to the Buckhead Creek Watershed, the City has several programs dedicated to educating the public about water quality and pollution. The City's website provides information about the Stormwater Program and the development of the Stormwater Utility and associated fees. It also contains information about the 24 -hour hotline where questions can be answered and stormwater problems related to drainage and pollution can be reported. An additional educational measure that could be considered would be to target those City residents that live adjacent to the stream. For this select group, quarterly newsletters could be mailed presenting information regarding the importance of not illegally discharging items (i.e. yard waste, car batteries, and other miscellaneous debris) into the stream. The newsletter should encourage the residents to keep the stream clean and report any blockage. Another approach would be coordinating with the local schools to teach the students about age appropriate stormwater issues. There are many benefits to teaching children about stormwater issues including the students relaying the information they learn in school to their parents. A presentation can be done in conjunction with an afternoon spent visiting and cleaning up the nearby stream. Adding an educational BMP near the school would be another outreach opportunity. Buckhead Creek Watershed Study Page 5 -1 WK Dickson & Co., Inc. SECTION 6 PERMITTING The proposed improvements described in Section 3 may require local, State, and /or Federal permits or approvals prior to the onset of construction. Based on the types of projects identified in the Buckhead Creek watershed, permits or approvals may be required for any of the following reasons: • Stream and /or wetland impacts. • FEMA floodway impacts. • Land disturbance. • Potable water and sewer line adjustments. • NCDOT ROW encroachment. The permitting matrix shown in Table 6 -1 shows the different types of permits that are anticipated for each proposed flood mitigation project. The water quality retrofits may require erosion control permits if the area of disturbance is greater than 1.0 acres, but permits or agreements from DWQ, ACOE, FEMA, and NCDOT are not anticipated for these projects. The types of 404/401 permits are described below and may vary based on the length of stream impacts and /or acreage of wetland impacts. Wetlands will need to be delineated to determine the acreage of impacts. Permit requirements for a given project may change based on the final design and any changes to the existing regulations. The appropriate permitting agencies should be contacted during the design process to determine if permits will be required for the proposed project. 6.1 North Carolina Division of Water Quality 401 Water Quality Certification and US Army Corps of Engineers 404 Permit Proposed improvements within the City of Fayetteville must adhere to the requirements set forth in Sections 401 and 404 of the Clean Water Act. Required permitting can range from activities that are pre- authorized to those requiring a pre - construction notification (PCN) for a Nationwide Permit (NWP) to those requiring an Individual Permit (IP). Individual permits may be required for projects with stream impacts greater than 300 feet and wetland impacts greater than 0.5 acres. It is anticipated that NWP #3 (Maintenance) and NWP #13 (Bank Stabilization) may be required to support the projects that include work within streams or channels that are claimed jurisdictional by the US Army Corps of Engineers ( USACE). Individual permits may be required for floodplain benches where significant wetland impacts may be encountered. More detailed explanations of the types of 404 permits are provided below. NWP #3 — Maintenance. This permit authorizes the repair, replacement or rehabilitation of any previously permitted or currently serviceable structure. A PCN is not required if minor deviations in the structure's configuration or filled area that occur as a result of changes in materials, construction techniques, or safety standards necessary to make repair or replacement, provided that environmental impacts are minimal. A PCN to the USACE is required if a significant amount of sediment is excavated /filled within the channel. NC Buckhead Creek Watershed Study Page 6 -1 WK Dickson & Co., Inc. SECTION 6 PERMITTING Division of Water Quality (DWQ) does not typically require a PCN for NWP 93 but usually receives one as a courtesy. Other provisions imposed by the State of North Carolina require that culvert inverts must be buried a minimum of 1 -foot below the streambed for culverts greater than or equal to 48 inches in diameter to allow low flow passage of water and aquatic life. Culverts less than 48 inches in diameter should be buried to a depth of 20% or greater of the diameter of the culvert. Table 6 -1: Permitting Matrix for Proposed Proiects NWP #13 — Bank Stabilization. This permit authorizes the reshaping of channel banks or bank stabilization activities that are necessary for erosion prevention. The placement of material is prohibited in any special aquatic site in a manner that may impede surface water flow into or out of a wetland area, or in a manner that will be eroded during normal or high flows. The activity must be part of a single and complete project and cannot exceed 1 cubic yard per running foot placed below the high water mark line. If stabilization activities exceed 500 linear feet, then a PCN is required for both the USACE and DWQ. DWQ must also be notified should fill be placed within the streambed.

This permit authorizes stream enhancement, stream restoration, and channel relocation for restoration purposes that provide gains in aquatic functions. Stream channelization and the conversion of streams to other aquatic uses such as impoundments or waterfowl habitat are not authorized. A PCN to the USACE is required for any restoration activities occurring on private or public lands. DWQ requires a PCN if impacts are proposed for greater than 500 feet of stream bank or if in- stream structures are used. Impacts proposed to the streams may need evaluation under the State Environmental Policy Act (SEPA). An Environmental Assessment (EA) is required under SEPA if greater than 500 linear feet of perennial stream is disturbed and stream restoration or enhancement is not performed. Channel disturbances are defined as activities that remove or degrade stream uses such as channelization, culvert placement, riprap, and other hard structures. A list of some other conditions that should be followed under regulations provided by the USACE and DWQ are as follows: • Soil erosion and sediment controls must be used and maintained in effective operating conditions during construction, and all exposed soil and fills should be stabilized at the earliest possible date. • No activity is authorized under any NWP that is likely to jeopardize the existence of a threatened or endangered species, or which will destroy or adversely modify the habitat of such species. • No activity is authorized that may affect historic properties listed or eligible for listing in the National Register of Historic Places. • More than one NWP used for a single and complete project is prohibited. • Impacts to waters of the US should be avoided and minimized to the greatest extent practicable. • Mitigation in all its forms will be required to the extent necessary to ensure that the adverse effects to the aquatic environment are minimal. • Hardening techniques should be avoided and minimized to the greatest practicable extent. 6.2 Individual Permits Individual Permits are required when stream or wetland impacts do not meet the conditions of a nationwide permit. Permit applications may be reviewed by multiple agencies including but not limited to USACE, DWQ, EPA, SHPO, NCWRC, and USFWS. The application is also made available for public review. There is no defined timeframe for review of the application for an IP; therefore the permitting process for an IP is typically significantly longer than the review time for a NWP. Typically 404 and 401 Individual Permits are applied for jointly and their review is concurrent. Buckhead Creek Watershed Study Page 6 -3 WK Dickson & Co., Inc. SECTION 6 PERMITTING 6.3 Mitigation For stream impacts greater than 150 linear feet or wetland impacts greater than 0.10 acres, mitigation is typically required. Mitigation can be provided onsite or by purchasing credits through a private environmental banker or the North Carolina Ecosystem Enhancement Program (NCEEP). Onsite mitigation may include stream restoration or wetland restoration /enhancement. As discussed in Section 3, removal of the Lake Francis dam would likely provide wetland and stream mitigation credits. 6.4 Federal Emergency Management Agency (FEMA) Streams with a drainage area greater than one square mile are typically modeled and mapped by FEMA for flood insurance purposes. A floodplain has been mapped for Buckhead Creek from approximately 3,330 feet upstream of the railroad tracks to the confluence with Little Rockfish Creek. Approximately 750 feet upstream of Raeford Road to the upstream limit of the study is defined as a Limited Detail Study where a floodplain is mapped, but no floodway has been defined. A floodway is the portion of the floodplain that must remain undeveloped to prevent an increase in the base flood elevation (BFE) of more than a specified amount. The specified amount as regulated by FEMA is typically 1.0 feet, although some communities regulate to a stricter standard. Any proposed projects that will include grading within a FEMA defined floodway will require a Conditional Letter of Map Revision (CLOMR) submitted to FEMA for pre - approval purposes and a Letter of Map Revision (LOMR) upon completion of construction. Table 6 -1 identifies the projects where FEMA permitting is expected. 6.5 Erosion and Sedimentation Control North Carolina Department of Environment and Natural Resources ( NCDENR) is another agency that requires notification before proposed activities are constructed. NCDENR requires that an erosion and sedimentation control plan be submitted to the Land Quality Section for approval before the start of construction for any disturbance greater than one acre. Erosion and Sedimentation Control permits are anticipated for most of the proposed projects as shown in Table 6 -1. Buckhead Creek Watershed Study Page 6 -4 WK Dickson & Co., Inc. SECTION 7 FUNDING OPPORTUNITIES 7.1 Water Quality Improvement Funding As the final design of the proposed improvements are evaluated, we would encourage the City to investigate the potential funding mechanisms that are available for water quality projects such as stormwater BMPs. There is a wide range of funding mechanisms available to the City for water quality improvement projects. Obvious sources include the Clean Water Act Part 319 funds administered by the US EPA and the North Carolina Cleanwater Management Trust Fund ( CWMTF). CWMTF funding can include land acquisition costs, design fees, and construction costs. Opportunities may be available to cost share with NCDOT. Several NCDOT roadways are located in the watershed including but not limited to Morganton Road, Cliffdale Road, Raeford Road, and Cumberland Road. NCDOT may be interested in cost sharing to fund a BMP that would treat runoff from NCDOT right -of -way in order to satisfy their NPDES permit requirements. The NCDENR Division of Water Resources offers grants for the following purposes: general navigation, recreational navigation, water management, stream restoration, beach protection, land acquisition and facility development for water -based recreation, and aquatic weed control. The following projects may be eligible for partial funding, specifically for the water quality treatment components: • Mary McArthur Elementary School Bioretention Pond and Grass Swale. • Douglas Byrd High School Bioretention Pond. • Douglas Byrd Middle School Bioretention Pond. • Ireland Drive Elementary School Infiltration Basin or Bioretention Pond. • William H. Owen Elementary School Bioretention Pond. 7.2 Flood Mitigation Funding FEMA's Flood Mitigation Assistance (FMA) is a pre- disaster grant program designed to provide funding to States and communities to help in their efforts to reduce or eliminate the risk of repetitive flood damage to building and structures insured under the National Flood Insurance Program (NFIP). In order to be eligible, communities must have completed and approved Flood Mitigation Plans that assess flood risk and identify actions to reduce that risk. Any State agency, participating NFIP community, or local agency is eligible to participate and should contact community officials. Buckhead Creek Watershed Study Page 7 -1 WK Dickson & Co., Inc. SECTION 7 FUNDING OPPORTUNITIES Additional project grant eligibility criteria include a project that is: • Cost effective. • Cost beneficial to the National Flood Insurance Fund. • Technically feasible. • Physically located in participating NFIP community or must reduce future flood damages in an NFIP community. A project must also comply with (1) the minimum standards of the NFIP Floodplain Management Regulations, (2) the applicant's Flood Mitigation Plan, and (3) all applicable laws and regulations. The State is the grantee and program administrator for FMA. FEMA distributes FMA funds to States that in turn provide funds to communities. FEMA may provide up to 75% of the total eligible costs. The remaining costs must be provided by a non - Federal source of which no more that half can be provided as in -kind contributions from third parties. The following projects may be eligible for partial funding, specifically for the flood mitigation components: • Raeford Road Culvert. • Raeford Road Floodplain Bench. • Coventry Road Culvert and Floodplain Bench. Buckhead Creek Watershed Study Page 7 -2 WK Dickson & Co., Inc. SECTION 8 COST ESTIMATES The cost estimates provided in this study were prepared to assist City staff in making planning level decisions and prioritizing improvements. These cost estimates are not final design estimates. These costs were developed using recent bid tabulations from other communities and NCDOT projects within North Carolina and include easement acquisition, surveying, engineering, legal, and administrative costs and potential mitigation costs. Mitigation costs will vary based on the presence of private mitigation bankers, the current rate of fee -in -lieu mitigation, and the amount of impacts. Land acquisition costs are excluded due to the variability of the real estate market. A detailed breakdown of the costs for the flood control projects listed below in Table 8 -1 is included in Appendix G. The cost estimates are approximate and are subject to change due to local costs for materials, delivery, construction, land or easement acquisitions, as well as other factors. Timeframes may vary based on regulatory agency reviews and easement negotiations /acquisition. All timeframes and cost estimates assume projects will be designed, permitted, and constructed individually. Combining the design and permitting of multiple projects may provide increased efficiencies and cost savings to the City. The stormwater drainage systems evaluated in this report are composed of a series of culverts, closed drainage systems, open channels, floodplain grading, and BMps. For these drainage systems to function as designed they must be properly maintained. Buckhead Creek Watershed Study Page 8 -1 WK Dickson & Co., Inc.

SECTION 9 PRIORITIZATION AND RECOMMENDATIONS As previously noted, the primary goal of this study is to make improvement recommendations to reduce flooding within the Buckhead Creek watershed. Currently, several conveyance systems do not meet the City hydraulic design requirements including sections with Buckhead Creek itself. WK Dickson has provided recommendations that help to reduce or eliminate the identified problems. Success criteria goals used to measure each proposed flood mitigation project included the following: • Providing improved level of service for roadways and structures. • Economic feasibility. • Minimizing stream and wetland impacts. • Confirming physical feasibility using available GIS and survey data. • Minimizing easement acquisition. Three different prioritization lists were developed for the proposed projects identified in Sections 3 and 4: Primary System Improvements, Secondary System Improvements, and Water Quality Projects. The Primary and Secondary System Improvements were prioritized based on the following factors: • Reduction in frequency and /or severity of residential flooding. • Reduction in frequency and /or severity of roadways. • Required sequencing of projects. • Stream and /or wetland impacts. • Capital construction cost. • Easement or land requirements. In some instances project prioritization will be impacted by the required sequencing of projects to provide the highest possible flood reduction benefits and to reduce or negate any downstream impacts from the proposed projects. Tables 9 -1 and 9 -2 show the proposed prioritizations for the Primary System and Secondary System Improvements. The City should re -visit the prioritization lists annually to determine if the priorities should change. Table 9 -I: Primary System Improvements Prioritization Prioritization Project 1 Coventry Road Culvert and Flood lain Bench 2 Raeford Road Flood lain Bench 3 Devonshire Drive Floodplain Bench and Glenwick Drive Berm 4 Raeford Road Culvert 5 Ferncreek Flood lain Bench and Floodwall 6 Lake Francis Wetland Enhancement/Restoration Buckhead Creek Watershed Study Page 9 -1 WK Dickson & Co., Inc. SECTION 9 PRIORITIZATION AND RECOMMENDATIONS Table 9 -2: Secondary System Improvements Prioritization Prioritization Project 1 Roxie Avenue 2 Buckhead Kingsford 3 Raeford Faison 4 Montclair 5 Ashton Road Friar Avenue 6 Ashton Road 7 Ashton Road Ramblewood Drive 8 Kimberly Drive 9 Ferncreek Norwood 10 Coventry 11 Westwood 12 Broyhill The Devonshire Drive Floodplain Bench and Glenwick Drive Berm should be constructed prior to the Raeford Road Culvert to reduce the impact of increasing the conveyance capacity under Raeford Road. If the City elects to use the Lake Francis Wetland project for mitigation instead of fee -in -lieu, then the wetland restoration would need to be completed prior to the Raeford Road Floodplain Bench or other projects that include significant impacts that require mitigation. The Lake Francis Wetland project may also provide stream credits which could be applied to the Buckhead Kingsford project. The Broyhill Secondary System project should not be completed unless the Raeford Road culvert improvements are completed. Due to the size of the Roxie Avenue and Buckhead Kingsford projects, the City may choose to phase construction of those projects. If the projects are phased, improvements should generally be constructed downstream to upstream. Table 9 -3 shows the recommended priorities for the water quality projects. As noted in Section 4, the prioritization is based on treatment area, impervious area treated, land ownership and accessibility, and cost.
