North Carolina 24802-1890 Attn: CESAW-CO-E Re: Pre-Discharge Notification Proposed Wal-Mart Store Fayetteville, North Carolina 6 1995 I;Dear Sir: 'AIL; Please find enclosed one copy of a Pre-Discharge Notification (PDN) and Joint Application Form for Nationwide Permits for the proposed Wal-Mart Store in Fayetteville, North Carolina, prepared by the Williamsburg Environmental Group, Inc. (WEG). Mr. Matt Flint of your staff has reviewed the delineation conducted by WEG and requested that we provide a metes and bounds survey of the wetlands prior to confirmation of the delineation. A copy of the survey is included within the document. Based upon this sun-ey, the subject property contains 2.34 acres of nonbdal, headwater wetlands. Wal-Mart Stores, Inc. proposes to construct a Wal-Mart shopping center on the subject property. As a result of the need for expansion in the vicinity of Fayetteville, various sites and land plans have been considered. The impacts to Aetlands on the selected alternative site have been reduced from 2.1 acres to 1.60 acres through avoidanc,- and minimization of till in wetlands. On behalf of Wal-Mart Stores, Inc., WEG respectfully requests that the U. S. Army Corps of Engineers (Corps) provide a confirmation of our delineation and process the enclosed PDN. By copy of this letter, wEG requests the North Carolina Department of Environmental Management (DEM) to review and process the Joint Permit Application as well. Please feel free to call me or Mr. David Ramsey at your convenience if you have any questions or comments. I look forward to %our response. Sincerely, /William J.

The proposed development is located in Cumberland County, North Carolina (see Vicinity Map). More specifically, the site lies in the northern portion of the intersection of Skibo Road (Route 401 Bypass) and Yadkin Road (SR 1415) (see Location Map). 3. The proposed 33.5-acre development involves the construction of an entrance road, parking areas, a retail store and stormwater management ponds. the 2.34 acres of wetlands on the ' property are associated with several depressions and drainage swales within a fallow pasture and forested areas. The forested wetlands in the northwest portion of the site are relatively undisturbed and are associated with intermittent surface drainage. These wetlands drain 1 northwest into Beaver Creek, a tributary of Little Rockfish Creek. Little Rockfish Creek drains to Rockfish Creek and eventually the Cape Fear River. Considerable effort has been spent preparing the plan of development to avoid impacts to the 1 wetlands on the site to the greatest extent practicable. Two feasible alternative development plans were considered. Alternative 1 (Map A) includes a 199,026 square foot Wal-Mart Super Center facing toward the south and two developable outparcels, with two stormwater ponds 1 placed in the forested wetlands along the western property line. As a result, the construction of this retail facility would unavoidably impact 2.10 acres of Section 404 jurisdictional wetland areas, including the hi;h value wetlands in the northwest corner of the site. The selected 1 alternative (Map B) presents the land plan which was prepared with consideration of avoidance and minimization of wetland impacts. The selected alternative includes rotation of the building to face the east. with a 200,089 square foot store and only one developable outparcel. In addition, this layout reduces the wetland impacts by 0.5 acre to 1.60 acres through avoidance of 1 the high value forested wetlands in the northwestern portion of the site. The impacts to jurisdictional areas are outlined on the grading plan (Map B). Additional impacts to the environment will be minimized through the implementation of strict erosion and sedimentation 1 control plans. This project will not impact any public water supply, shellfish harvesting area, spawning grounds, or waterfowl habitat; nor jeopardize any threatened or endangered species of which we are aware; nor disrupt the movement of aquatic life. 1 The impacts associated with this development meet the conditions of the Corps' Nationwide #26 permit. This Pre-Discharge Notification (PDN? is submitted in accordance with General Condition # 13 of Appendix A of 33 CFR Part 330 for the 1.60 acres of nonddal headwater wetland impacts associated with the construction of this project. The following table describes the wetland impacts associated with the development of the proposed 33.5-acre retail facility as shown on the grading plan (Map B). i 2 1 ?I Total Impact Area Type Area (Acre) Area (acre) PFOIA 0.97 0.87 11 PFOIA 1.00 0.36 III PFOI/SS1A 0.34 0.34 IV PFOIA 0 03 0.03 Total 2.34 1.60 The nontidal headwater and isolated wetlands to be impacted are associated with a fallow field and adjacent forest. Wal-Mart Stores, Inc. has made attempts to avoid and minimize impacts to wetlands to the greatest extent practicable. The proposed impacts are to those wetlands which have been historically manipulated through ditching or other disturbance. The wetlands to be preserved in the northern and northwestern portions of the property exhibit no historic disturbance and are associated directly with the surface flow to Beaver Creek. Due to the limited space onsite and the low relative value of the wetlands to be impacted versus those to be preserved, no onsite mitigation area is available. The Williamsburg Environmental Group, Inc. (WEG) has conducted a pre-application telephone conversation with Mr. Matt Flint of the Wilmington District Corps. The Corps indicated that the project may be permitted without compensation, provided avoidance and minimization of impacts are demonstrated and the North Carolina Division of Environmental Management (DEM) issues a 401 Certification and requires no such mitigation. Appendix A includes a Joint Permit Application for Nationwide Permit #26. Wal-titart Stores, Inc. and WEG conducted an analysis of alternative site plans in an effort to avoid and minimize impacts to wetlands to the greatest extent practicable (see appendix B). A jurisdictional wetland delineation was performed by WEG in March, 199-5. This delineation was verbally confirmed by Mr. Matt Flint of the Corps, pending a metes and bounds survey of the flagging. The data sheets used in the delineation are enclosed in Appendix C. Map C depicts the wetlands map which was submitted to the Corps for confirmation. As a result of the field visit by Mr. Matt Flint of the Corps, two small areas labeled as Area I on the submitted map, were determined to be non-jurisdictional. Map D presents a metes and bounds survey of the wetland flagging per the Corps' request. The areas determined to be non-jurisdictional by the Corps are labeled "Wetland H" and "Wetland U' As required by the Corps, WEG has contacted the U. S. Fish and Wildlife Service, the National Marine Fisheries Service and the State Historic Preservation Office regarding the presence of any Federally listed (or proposed for listing) endangered or threatened species and/or the presence of any historic properties in the permit area that may be affected by the proposed project. At the time of the correspondence with these agencies, the full extent of the impacts as a result of stormwater management facilities was not known. The impacts, therefore, are listed as 1.498 acres in the letters as opposed to 1.60 acres, which includes all impacts to wetlands under the current plan. Please refer to the letters-in Appendix D for details regarding this correspondence. As required by the DEM, the stormwater management plan is included in Appendix E.

City Sewer 1 A9 OWNER'S Si NATURE DATE r II LJ U U 11 APPENDIX B ALTERNATIVE ANALYSIS F7 u n U 1.0 ALTERNATIVES ANALYSIS I The proposed Wal-Mart Store site was selected based upon its location relative to the existing commercial areas in Fayetteville, North Carolina, the unavailability of 30+ acre sites in the corridor, and site ' limitations such as topography, wetlands and existing roads. The construction of this 200,089 square foot store will serve to provide a new location for the existing Wal-Mart Store located approximately 1/4 mile south on Skibo road in the Cross Creek Shopping Center. The existing store is currently the national store of the year based upon volume of sales, however sufficient space is not available in the structure to warehouse the volume of goods moving through the facility. As a result, Wal-Mart Stores, Inc. elected to create a larger facility which is capable of handling the volume of a national store of the year. 1.1 ALTERNATIVE SITES As a result of the need for expansion, Wal-Mart Stores determined that only two possible locations for the new facility were available. The existing Wal-Mart was determined to be unsuitable based upon physical site constraints. The selected site rates very high in the siting criteria used by Wal-Mart Stores, Inc. based upon its lack of engineering :onstraints and location relative to commercial centers within the corridor. The existing Wal-Mart location was considered for expansion. Site constraints, including the existing commercial infrastructure in the vicinity and existing traffic congestion indicated that the present store location may not be suitable for expansion. Additionally, the area to the rear of the existing store would require extensive quantities of fill material for expansion of the facility, thereby creating an engineering and economic constraint for the expansion potential of the store. The presence of additional ?0+ acre parcels was investigated for the construction of a new shopping center along the Skibo Road corridor, in the vicinity of the existing store. Only one site was located which met the size requirements for the larger facility. This is the selected site, located at the intersection of Skibo and Yadkin Roads, approximately 1/4 mile north of the existing store. The characteristics of this site, including the location with respect to other commercial centers in the area, the traffic management capabilities and the physical condition of the site provides for one of the highest rated potential Wal-Mart Store sites, based upon Wal-Mart Stores, Inc. siting criteria. '7 1 I__ J 1.2 ALTERNATIVE LAND PLANS The selected property encompasses approximately 33.5 acres of forest and fallow pasture, with 2.34 acres of jurisdictional wetlands. The majority of the wedands onsite have been historically disturbed through ditching and land clearing. Within the northwest corner of the site, an undisturbed area of nontidal, forested wetlands drains to the north into Beaver Creek. The remaining wetlands onsite are associated with ditched areas or drain into storm sewer pipes. Several land plans were developed for an approximate 200,000 square foot shopping center. Two basic configurations were considered. One configuration is depicted in Alternative 1 (Map A), with the store located in the northern portion of the site facing south. The alternative configuration included placing the store in the western portion of the site facing east, as shown on Map B. Based upon these two possible configurations, parking, traffic and stormwater management facilities were then designed to minimize impacts to wetlands onsite, particularly the undisturbed wetlands in the northwest portion of the site, to the greatest extent practicable. 1 .2.1 Alternative 1 Alternative 1, shown in Nlap A, provides a 199,026 square foot Wal-Mart store in the northern portion of the site, facing to the south. This configuration allows for one out parcel in the southwest portion of the site, where the existing NAPA store is located, and another across the Wal-Mart entrance road. The two out parcels would be the future location of fast food or smaller retail facilities. Under this plan, two stormwater management ponds are located along the western portion of the site. The southern most pond is located mostly in uplands, with impacts to approximately 0.34 acre of wetlands that currently drain into storm pipes. The northern most pond is situated in the high value wetlands at the northwestern portion of the site, and impacts approximately 0.65 acre of this wetland. The impacts from stormwater management and the building total 2.1 acre under this alternative. As a result of the impacts to wetlands required by this plan, Wal-Mart Stores, Inc. attempted to move the northern most pond from the high value wetlands and into the narrow, north-central portion of the site. This move would result in less impact to wetlands. The configuration of the building, however, does not ' allow for the creation of a pond at the rear of the store due to its proximity to the property line. Alternative 1 was determined to be non-practicable due to the impacts tp high value wetlands resulting from the stormwater pond. I I I I I I I I I I I I I I I I I I I 1 1.2.2 Selected Alternative The selected alternative is shown in Map B. This alternative was developed in an effort to allow for stormwater management facilities in the narrow, northern portion of the site. This alternative provides for a 200,089 square foot store in the western portion of the site, facing east toward Skibo Road. Two stormwater management ponds are included in the plan, as with Alternative 1. The southern most pond is located along the intersection of Yadkin and Skibo Roads, in the approximate location of the out parcels ' shown in Alternative 1. As a result of the rotation of the store, the northern most pond is sited in the narrow strip of land in the northern portion of the site, thereby allowing for preservation of the majority of the undisturbed wetlands in the northwestern portion of the site. Under the selected alternative, the store has been rotated, one out parcel has been eliminated and the wetlands impacts are reduced by 0.5 acre, to a total of 1.60 acres of low value wetlands, through avoidance and minimization of the fill required in the high value wetlands. The remaining 0.74 acre of high value wetlands on the site will be preserved. n L li u E 1 11 F APPENDIX C WETLAND DELINEATION DATA SHEETS I WEG DATA FORM ROUTINE WETLAND DETERMENATION (1987 COE Wetlands Delineation Manual) Project/Site: FAYETTEVILLE Date: 3121195 Applicant/Owner..

INC. 209 WEST STONE AVENUE, GREENVILLE, S.C. 29609 J 1 ' Wal-Mart Store # 1238 Fayetteville, N.C. ' STORMWATER MANAGEMENT REPORT The following is the stormwater management report for the new Wal-Mart store to be built at the intersection of Yadkin Road and Skibo Road. The site will be developed to contain a +/- 200,000 sT Wal-Mart store and accompanying parking and landscape areas. The stormwater system will be an underground system using catch basins and pipes which ' will convey runoff to one of two on-site ponds. These ponds are sized to handle the 2 year and 10 year storm events and will have staged outlets to manage each storm. All release ' will be restricted to pre-developed rates. No runoff will enter the existing stormwater systems belonging to the Department of Transpiration. All runoff will be directed to the low areas that currently pick up runoff from this site. ' The site is being divided into two sections with a pond to serve each section. These stormwater calculations are also setup to present the runoff values and release rates for ' each pond. The ponds are referred to in this report as Pond #1, the north pond, and Pond # 2, the south pond. ' The runoff calculations shown in this report are based on the Soil Conservation Service method TR-55 with plotted hydrographs included. ' Eaistine Conditions: The site currently is comprised of large fields (grassy areas) that contain a few small ' residential structures. These structures will be removed to accommodate Wal-Mart's construction. The remainder of the site is comprised of wooded areas that contain small pockets of wetlands per the environmental report by the Williamsburg Environmental ' Group (WEG). The permits for filling these wetlands is being obtained by WEG. The runoff currently follows two tracts. The northern portion of the site flows to a small ditch ' in the middle of the site which traverses north across the site to a large draw that carries the water to an existing creek to the west of the site. This draw also picks up approximately 14.18 acres of off-site runoff as per the USGS map. This off-site runoff will ' continue to flow to this draw when construction is complete and is accounted for in the design. The southern portion of the site flows west to two ditches along the western property line. These ditches feed two 18" pipes that carry the water under a mini ' warehouse development and eventually to the same creek that catches the northern portion of the site. The closest body of water to the site is a branch of Beaver Creek and the site does not lie within the 100 year flood plain. This site also lies outside of the ' watershed area. r I POINT "A", POND # 1 Existing Conditions: The areas draining to Point `A' are comprised of the follow; The soils are made up of three classifications, type A, type B, and type C hydrologic soils groups. These soils can be found in bands as one goes from east to west across the site. This area is comprised of wooded areas which should be classified as good condition, and a small portion of pasture land or grassland which is somewhat sandy and in fair condition. The drainage basin can be broken down into small sub-areas which eventually flow together at point A. These sub areas are shown on the drainage map included in the drawings and are as follows: Area 1 - Off-site runoff - 14.18 acres, wooded Area 2 - On-site - 3.26 acres, wooded Area 3 - On-site - 8.18 acres, wooded Area 4 - On-site - 3.06 acres, wooded, grassland ' From the drainage area map it can be seen that area 3 drains to area 4 and the two combined drain to area 2. These three areas combine with area 1 for the total, pre- developed discharge at point `A'. ' Runoff Curve Number: ' The runoff curve number for each area is based on soil group and type of existing vegetation, paving, etc.. The runoff curve for each area is as shown on the included TR-55 printouts and are as follows. Area # 1 Off-bite Area # Z Area # 3 Area #4 CN=71 CN=59 --+CN CN=76 ' Time of Concentration: The time of concentration for each area will be calculated using three types of flow. Sheet flow for the first 300 feet, Shallow Concentrated flow for any sheet flow after 300 feet, and Open channel flow for any flow through pipes or ditches. The time of concentration is a function of slope, the roughness coefficient of the surface the water is flowing over, and in the case of open channel flow, the velocity. This number is used in determining the runoff from the site over time and subsequently to develop the hydrograph. Tc is as follows for each area: Area # I Off-Site I Area # 2 1 Area # 3 Area # 4 Tc = .40 hrs. Tc = 1.41 hrs Tc = 1.17 hrs Tc = 1.08 hrs I I ' From the Tc and the Runoff Curve Number the total runoff for each area can be determined. ' Runoff Calculations - Tabular Hvdrograph Method Per the TR-55 program the runoff will be calculated for each area and a hydrograph will ' be generated for each area. This will be done for the 2 year, 10 year, and 100 year storm events. After each hydrograph is generated the areas will be combined to provide the final hydrograph of the entire drainage basin. Refer to the calculations for these runoff numbers ' and hydrographs. Since Area #1, Off-Site, will not be disturbed, it will be combined with the on-site after all runoff has been calculated to the point at which it joins the off-site runoff path. Hydrographs 2, 3, and 4 are joined together (hydrographs # 6 and # 7), and ' then the resulting hydrograph is joined with hydrograph #1 to get the total runoff to point `A'. The results are as follows: Pre-Developed ff Rates Storm Event Area #1 Areas #2,3,&4 Total to Point A 2 year 3.66 cfs 2.87 cfs 5.89 cfs 10 year 9.87 cfs 8.68 cfs 17.14 cfs Develoned Condition to Point `A' Next the developed condition will be evaluated for the drainage area to Pond # 1 and ultimately to Point `A'. As stated before, the off-site area is not impacted by the development so this runoff number will be the same as in the pre-developed condition. The off-site runoff does not flow through the stormwater pond so to obtain the total to point `A', the off-site hydrograph will be combined with the stormwater pond routing hydrograph and this total can not exceed the pre-developed total runoff. Runoff Curve Number The developed condition will consist of parking areas and a portion of the roof area. This water will sheet across the parking lot to catch basins and be conveyed via pipes to Pond #1. Pond # 1 will also be sized to accommodate an outparcel in its developed state. The configuration of the site allows for a 4.82 acre outparcel on the north end at Skibo Road. This outparcel will be assumed to have a total runoff number of 86. The runoff curve numbers are as follows: Runoff Curve Numbers Post Developed Condition On-Site Open Space CN = 61, 0.71 acres Impervious Area CN = 98, 10.7 acres Newly Graded Area CN = 86, 4.82 acres Out Parcel Total Runoff Curve Number CN = 93 7 J Time of Concentration The time of concentration for the developed condition will be comprised of sheet flow for the first 300, shallow concentrated flow for 70, and open channel flow for 475 feet. Tc = 0.07 hrs. Graahical Peak Discharge The developed condition for runoff is calculated using the TR-55 method and a' hydrograph is developed from these calculations. The calculations are performed for the 2, 10, 25 and 100 year storm events and the results will be taken through Pond # 1 to develop a Reservoir Routing Hydrograph. These hydrographs will be combined with the off-site hydrograph to get the total runoff to Point 'A'. The results are as follows: Post Develo e&Runoffto Pond # 1 Storm Event Runoff cfs 2 year 42.59 cfs 10 year 71.27 cfs 100 year 107.60 cfs These numbers will be used to develop hydrographs through the pond.

RUNOFF Hydrograph No. 9 I J I r POND # 1 SIZING AND ROUTING Pond # 1, as can be seen on the grading plan, will be a surface pond with a bottom ' elevation of 222.0 and a top elevation of 230. This gives a total volume of 190631 cf. Stage / Discharge and Stage / Storage charts are included in this report. Once the pond volume is known an outlet structure must be designed to limit outflow from the pond to a ' pre determined amount. The outlet structure is designed to limit flow in stages, limiting the 2 year storm event to pre-developed 2 year rate, the 10 year storm event to 10 year ' pre-developed rates, etc.. The outlet structure will consist of a box with an orifice at the outlet elevation to control the 2 yr., a weir at the 2 yr. storage elevation to control the 10 yr. and an emergency spillway to release the 100 year event. The outlets will be sized as ' follows; Orifice Equation - Q= 0.6 x A x (f2gh) x 1 Weir Equation - Q = 3.0 x (L) x (H^1.5) ' From these equations it is determined that a 6" orifice at elevation 222.0 will control the 2 yr. storm and a 4.5' weir at elevation 228.0 will control the 10 yr storm. Refer to the hydrographs for reservoir routing. The results are as follows: Pt?ND # 1 _, Storm Stage Volume Release 2 226.78 106048 cf 1.95 cfs 10 yr 228.55 151024 cf 7.79 cfs These runoff hydrographs are now combined with the off-site hydrograph (hydrograph #1) to get the total runoff.

The spillway will take into account the amount of flow released from the outlet structure and the difference from this amount and the amount of the 100 year runoff is the basis for the size of the spillway. From the stormwater calculations the 100 year rainfall event produces 107.6 cfs. Q,oo= 107.6 cfs QE = Emergency spill way release QS = Structure release QE = 107.6 cfs - 15.73 cfs = 91.87 cfs Size emergency spillway for 91.87, i.e. 92.0 c6 release. From the weir equation this would require a 30.6 foot weir with one foot of head. The spillway elevation is 229.0 and the top of the dike is 230. To add a factor of safety into the design make the spillway 40 feet wide. This gives a head elevation of 0.8 feet.

The total area is 5.82 acres. There is another areas next to Yadkin Road that drains towards the road but since it does not contribute to the runoff at Point B it will not be considered. Point B is an 18" rcp that is located at the west side of the site and currently drains under a mini warehouse complex to an open ditch that leads to a branch of Beaver Creek. The 5.82 acres drains from east to west by mainly sheet flow at low to moderate slopes. Runoff Curve Number: The runoff curve number for the existing condition will be based on the total acreage for each type of use and soil type. Of the 5.82 acres, 2.18 acres are considered type B soils and 3.64 acres are considered type C soils. t Soil Type B Soil Type C 2.18 ac. CN=61 3.64 ac. CN=74 Weighted CN = 69 Time of Concentration: The time of concentration for the existing condition will be based on two sections of flow. r The first section is 300 feet of sheet flow and the second section is 580 feet of shallow concentrated flow. i Tc = .46 hrs. Tabular Hydrograph Method: The runoff calculations will be run for the 2 yr, 10 yr, 25 yr, and 100 yr storm events to obtain the pre-developed release rates. A pond will then be designed to handle the 2 yr, l Oyr and 100 yr storm events.

The outlets will be sized as ' follows; Orifice Equation - Q= 0.6 x A x (.r2gh) x 1 Weir Equation - Q = 3.0 x (L) x (H^1.5) 1 From these equations it is determined that a T' orifice at elevation 222.0 will control the 2 yr. storm and a 1.6' weir at elevation 225.8 will control the 10 yr storm. Refer to the hydrographs for reservoir routing. The results are as follows: Storm Stage Volume Release 2 225.51 79067 cf 2.17 cfs 10 yr 226.66 118562 cf 6.20 cfs These runoff hydrographs are now combined with the off-site hydrograph (hydrograph #1) to get the total runoff. This number is compared to the pre-developed rate to insure that runoff is equal to or less than the pre-developed number. c Actual Release Rate Allowable Release Rate 2 yr - 2.17 cfs 2.19 cfs .-. ok 10 yr - 6.20 cfs 6.25 cfs, .-. ok n L 1 i 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 ?'? , p -Z Z HYDROLOGIC REPORT_ STAGE / STORAGE / DISCHARGE RESERVOIR NUMBER = 2 RESERVOIR NAME = SOUTH POND..
