DONALD W. GARNER / ISAKSON-BARNHART, 25 TECHNOLOGY PARKWAY SOUTH, SUITE 201, NORCROSS, GEORGIA, 30092, has requested a Department of the Army (DA) permit TO AUTHORIZE THE PROPOSED RELOCATION OF UNNAMED TRIBUTARIES OF LITTLE CREEK AND THE DISCHARGE OF FILL INTO ADJACENT WOODED WETLANDS ASSOCIATED WITH THE PROPOSED CONSTRUCTION OF COMMERCIAL RETAIL DEVELOPMENT, LOCATED OFF OF HANES MALL BOULEVARD, IN WINSTON-SALEM, FORSYTH COUNTY, NORTH CAROLINA. The following description of the work is taken from data provided by the applicant and from observations made during a site visit by a representative of the Corps of Engineers. Plans submitted with the application depict permanent impacts to 0.32 acre of wetlands and 0.23 acre (A'67 linear filet) of streams (total of 0.55 acres of impacts to jurisdictional waters of the United States). The applicant for the 35-acre project is proposing a commercial retail center involving the construction of approximately 300,000 square feet of commercial retail space, associated access roads, and a required stormwater management facility. The site is divided into two small drainages. The western drainage consists of an intermittent stream/forested headwater wetland with an onsite drainage area of 14 acres and an offsite drainage area of 8 acres. This tributary flows into a 42-inch culvert under Hanes Mall Boulevard. The eastern drainage is somewhat larger with an onsite drainage area of approximately 25 acres and an offsite area of approximately 10 acres. Drainage within this section enters the property from two existing culverts and exits the project through a 54-inch culvert under Hanes Mall Boulevard. The existing streams have been degraded by past upstream and adjacent urban activities as evidenced by unstable eroded banks, silted.stream..bottoms,.and the.presence of substantial vegetative debris. The proposed project will permanently impact, by culvert and fill, 0.55 acre (approximately 0.32 acre of jurisdictional wooded wetlands and 0.23 acre/867 linear feet of jurisdictional stream channels) of waters of the United States associated with unnamed tributaries of Little Creek. The purpose of the work is to provide for the construction of a commercial retail development within a section of Hanes Mall Boulevard that has and continues to experience ongoing commercial development. The project's location makes this site desirable for commercial users who want to utilize the adjacent, existing roadway infrastructure and existing commercial enterprises. Plans showing the work are included with this public notice. 2 The State of North Carolina will review this public notice to determine the need for the applicant to obtain any required State authorization. No Department of the Army (DA) permit will be issued until the coordinated State viewpoint on the proposal has been received and reviewed by this agency, nor will a DA permit be issued until the North Carolina Division of Environmental Management (NCDEM) has determined the applicability of a Water Quality Certificate as required by PL 92-500. This application is being considered pursuant to Section 404 of the Clean Water Act (33 U.S.C. 1344). Any person may request, in writing within the comment period specified in the notice, that a public hearing be held to consider this application. Requests for public hearing shall state, with particularity, the reasons for holding a public hearing. The District Engineer has consulted the latest published version of the National Register of Historic Places for the presence or absence of registered properties, or properties listed as being eligible for inclusion therein, and this site is not registered property or property listed as being eligible for inclusion in the Register. Consultation of the National Register constitutes the extent of cultural resource investigations by the District Engineer, and he is otherwise unaware of the presence of such resources. Presently, unknown archeological, scientific, prehistorical, or historical data may be lost or destroyed by work under the requested permit. The District Engineer has determined, based on a review of data furnished by the applicant and onsite observation, that the activity will not affect species, or their critical habitat, designated as endangered or threatened pursuant to the Endangered Species Act of 1973. The decision whether to issue a permit will be based on an evaluation of the probable impacts, including cumulative impacts, of the proposed activity and its intended use on the public interest. Evaluation of the probable impacts which the proposed activity may have on the public interest requires a careful weighing of all those factors which become relevant in each particular case. The benefits which reasonably may be expected to accrue from the proposal must be balanced against its reasonably foreseeable detriments. The decision whether to authorize a proposal, and if so the conditions under which it will be allowed to occur, are therefore determined by the outcome of the general balancing process. That decision should reflect the national concern for both protection and utilization of important resources. All factors which may be relevant to the proposal must be considered including the cumulative effects thereof.

August 16, 2000 Mr. John Thomas US Army Corps of Engineers 6508 Falls of the Neuse Road, Suite 120 Raleigh, North Carolina 27615 Re: Winston-Salem Site, USACOE # 200020130, NCDWQ # 99-1172 Winston-Salem, North Carolina Environmental Consultants This correspondence will follow up our discussions regarding the above-referenced application submitted to you for the development of a 35-acre parcel located in Winston-Salem, North Carolina. Based upon your request, we initiated an offsite review of available compensatory mitigation areas within the Winston-Salem area. As I have conveyed to you previously, our client does not own additional land in the Winston- Salem area. As such, our efforts focused on finding available land with property owners willing to either sell their property or at least commit to having the compensation area and associated upland buffer protected under a suitable deed restriction. Our analysis of available land suitable for restoration included the assistance of the Meridian Realty Group located in Winston-Salem, NC, the City of Winston-Salem, and the North Carolina Housing Foundation., We examined 10 sites in the Winston-Salem area for potential restoration and one near Kemersville. The following represents a summary of our analysis documenting the sites that were examined for potential stream restoration. We have also included several photographs that document the site conditions we encountered. Potential sites were evaluated based on the following criteria. • Existing Wetlands • Land Use • Existing Vegetation • Access • Utilities • Topography • Soils • Future Development Potential • Floodplain Elevation • Available Spoil Area • Drainage Area • Mitigation Requirement 1. The first site was located along Mill Creek just south of Stanleyville. The site is associated with a 9-acre remnant of the larger Vulcan Tract. This larger area serves a variety of landuse including industrial and residential development. The majority of the 9- acre property lies within the floodplain and approximately 60 percent of the site can be categorized as jurisdictional wetlands. A utility line runs parallel to Mill Creek throughout the property. At this location, Mill Creek as a drainage area of approximately 5000 acres (8 square miles). The 20-foot wide creek is bounded to the south by 30-foot slopes heavily vegetated with mature tree canopy. The northern bank is 6-8 feet high and is also vegetated with a mature tree canopy. Topography within the project area is relatively uniform and the creek makes a gentle meander as it enters the property. 3000 Easter Circle • Williamsburg, Virginia 23188 • (757) 220-6869 • FAX (757) 229-4507 Mr. John Thomas August 16, 2000 Page 2 While it is evident that large portions of Mill Creek have been historically impacted through channelization and activities on adjoining uplands, the site fails to meet basic criteria for restoration. The side slopes are relatively stable and heavily vegetated with mature trees. Access to the site is limited. along the southern shore and the presence of jurisdictional resources and the buried utility further limits the available upland. The drainage area for the proposed Winston-Salem development located in the headwaters of Little Creek is approximately 118 acres (0.18 square miles). At 8 square miles, the Mill Creek watershed is significantly larger. As such and in consideration of the site as a whole, the Mill Creek site was determined to be unsuitable and eliminated from further consideration. 2. The second site is associated with an unnamed tributary to the South Fork of Muddy Creek. The site has a drainage area of approximately 50 acres. The site is also heavily vegetated with mature tree species and we have recently learned that the landowner has expressed a reluctance to place deed restrictions on the property. For this reason, this property was eliminated from further consideration. 3. , A third site involved portions of land controlled by the North Carolina Housing Foundation along a headwater reach of a stream segment associated with the West Fork Deep River in Kernersville. The site has a small drainage of less than 50 acres with no peak attenuation or treatment of stormwater discharged from surrounding development. While the stream continues to be heavily impacted by peak flows, site restoration, is constrained by existing utilities, the presence of mature hardwood trees and the prevailing steep topography. A potential candidate for restoration, the primary focus of a remediation effort in this setting should be stormwater management. When you combine this understanding with an evaluation of the site constraints, the limited drainage area, and compare it to our goal for compensatory mitigation, this site falls short of the quantity of mitigation required. For this reason, this site was eliminated from further consideration. 4. The next site we inspected is located on property owned by the School of the Arts in Winston-Salem. The site drains approximately 60 acres adjacent to the school and flows into Salem Creek below Central Park. The existing stream channel is bounded by very steep slopes covered in Kudzu which give way to existing development on either side of the riparian corridor including right-of-way for existing roadways and home sites. Destabilizing these slopes with channel modifications is not recommended. Such a proposal would involve significant grading and encroachment into surrounding lands including the adjacent home sites. Enhancement through riparian plantings and the control of Kudzu may be an option but the overall project area is not sufficient to meet the compensation requirements. In addition, the site has a small drainage area that brings into question the status of the stream as a perennial feature. 5-8. The City of Winston-Salem has recently begun an evaluation of stream channels within City property with the goal of restoring eroded and problem areas in the Muddy Creek watershed. The City has been awarded a $ 985,800.00 grant through the Clean Water Management Trust Fund for these purposes. The focal point of their evaluation is the Salem Creek drainage. The City chose Salem Creek because it is on North Carolina's Mr. John Thomas August 16, 2000 Page 3 April 3, 2000 § 303(d) list of waters nonsupporting in its uses. " The Salem Creek watershed is mostly urban and drainsall of downtown Winston-Salem. The total drainage area of Salem Creek within the study area is approximately 13,700 acres (21 square miles). Through the City's scoping efforts, they have identified three reaches of Salem Creek in need of restoration. We inspected these sites with the City on June 27, 2000 and looked for areas where we could expand on the City's existing effort by restoring additional areas within the main stem of the waterway. The first site (Site 5) is located in Central. Park just south of downtown off Main Street. The length of restoration proposed is approximately 1050 linear feet. This section of stream is severely eroded and is threatening utility infrastructure. The second segment (Site 6) is located at the Martin Luther King Jr. Drive Bridge in Civitan Park. The length of restoration in this area is approximately 2500 linear feet. This site is also experiencing severe erosion in stream meanders. The third site (Site 7) is located on Brushy Fork Creek in Bowen Park situated just off of New Walkertown Road east of downtown Winston-Salem. This 2200-foot section has 10-foot vertical banks and is about to claim an electrical transmission tower. We also examined a portion of Brushy Fork Creek downstream of the City project (Site 8) but the linear distance was not sufficient to meet the compensation requirement. 9. We also inspected tributary streams in close proximity to the proposed restoration. The tributary systems we examined tend to be unstable channelized conveyances designed to expedite water movement into the adjacent receiving body. The existing conditions vary between sections but include scour and excessive sediment deposition along with a little to no riparian buffer. We believe these areas represented a good opportunity to provide stream restoration in keeping with the impacts proposed for the Hanes Mall Boulevard development. A portion of stream locally mapped as Stadium Branch in the Civitan Park area has an 1100-foot section just upstream of the confluence with Salem Creek that we felt would meet your restoration requirements. The drainage area for this section is approximately 220 acres (0.34 square miles). The majority of this stream is nothing more that a "Y' channel cut into the surrounding upland. The channel slopes are vegetated with grass but this straight linear feature is functioning more as a flume directing the erosive force of stormwater directly into the streambanks of Salem Creek. 10-11.Two additional tributaries located within the Central Park/Happy Hill Park project area were also examined for restoration opportunities however the linear distance of these combined systems is only 650 feet. In addition, Ms. Jennifer Frye (NCDENR) indicated that we could not propose restoration in an intermittent waterway. Both of these areas were considered intermittent based on our inspection and as such unsuitable. The only viable site identified during this review was located along Stadium Branch (Site 9) on property owned by the City of Winston-Salem. Stadium Branch is a tributary to a portion of Salem Creek that is scheduled to undergo enhancement/restoration under the grant from the Clean Water Management Trust Fund. Unfortunately, following conceptual plan preparation and tentative approval by you during our July 26, 2000 site inspection, the City declined use of the site due to the potential to impact recreation areas in the park. Mr. John Thomas August 16, 2000 Page 4 Over .the course of the last three months, we have made every effort to identify a suitable compensation area. And while we were successful in identifying an area that met with your tentative approval, the property owner ultimately denied the proposed action. We have now reached a stage in the evaluation process where we have no viable alternative but to request authorization for compensatory mitigation through a contribution to the North Carolina Wetland Restoration Program (WRP). On behalf of our client, the Williamsburg Environmental Group, Inc. (WEG) respectfully requests that the Corps and the North Carolina Department of Environment and Natural Resources issue their respective permits contingent upon our proposed mitigation. I have forwarded a letter to Mr. Ron Ferrell soliciting the WRP's acceptance of our request. If you have any questions, please feel free to call me at your convenience.

Williamsburg Environmental Group, Inc. (WEG) has been retained to provide environmental services for the above-referenced parcel. This process began back in October 1999 with the submission of a permit application involving impacts to jurisdictional resources regulated by the U.S. Army Corps of Engineers (Corps) and the North Carolina Department of the Environment and Natural Resources, Division of Water Quality (DWQ). Enclosed is a copy of the original application along with subsequent submittals made during the course of the agency review. The construction of this development including the stormwater management facility will require direct impacts to 0.32 acres of nontidal-forested headwater wetlands, 0.07 acres of other waters of the U.S. and 867 linear feet of stream channel. The applicant has worked diligently to avoid and minimize impacts to natural resources to the greatest extent practicable, however in this instance, impacts to jurisdictional resources are unavoidable. In an effort to compensate for permanent unavoidable impacts, the applicant proposed to mitigate these impacts through a contribution to the North Carolina Wetlands Restoration Program (WRP). In my latest conversation with both the Corps and DWQ, they are requesting 1:1 compensation for 867 linear feet of stream channel. Prior to approving a WRP mitigation proposal, both the Corps and DWQ recently requested that our client investigate additional offsite opportunities for stream restoration. Our client does not own additional land in the Winston-Salem area and as such, our efforts focused on finding available land with property owners willing to either sell their property or at least commit to having the compensation area and associated upland buffer protected under a suitable deed restriction.

Project Description The project is being proposed to be developed to contain a 148,000 sf Costco, two 30,000 sf "mini-anchors", a 6,400 sf restaurant, a 5,000 sf restaurant, and various shops space totaling 46,100 sf. The site will consist of these buildings, as well as the associated parking, storm drainage, landscaping, and detention facilities. Treatment Procedures: We are proposing a wet detention basin to effectively treat and release the stormwater runoff. The proposed basin has been designed to be located in the northeast comer of the property adjacent to Hanes Mail Boulevard. The stormwater will be collected using a series of catch basins and drop inlets. Once the stormwater enters the catch basin or drop inlet, it will be carried via the storm drain network to the wet detention pond. The runoff will enter the forebay for settling of the stormwater. A vegetated shelf has been created just below the permanent pool elevation of the pond to filter sediment and improve overall water quality. The storm drain network will create some storage area for the pond that has been neglected in our study for a conservative design. The pond was designed using NCDENR guidelines for sediment removal. The design of the pond was performed using a 85% TSS removal. The pond and forebay was designed to be 6' deep. The proposed surface area for the basin meets the required surface area. Due to constraints on the site, it was impractical to design the pond to have an emergency outlet that drained the pond via gravity flow. In the case of an emergency and the pond has to be drained, we are proposing to bring portable pumps in to drain the pond. These pumps will beset up to drain through the outlet device. We have designed the outlet structure(s) to control the 1-inch, 2-yr, I0-yr, & 25-yr storms to pre- developed rates. The 50yr & 100-yr storms will be routed through the structure without overtopping the pond. The 1-inch rainfall is being controlled by using (2) 2.7" orifices to release the 1" runoff in a 2-5 day time period. The larger storms are controlled by a variety of orifices and weirs to release the runoff at a predeveloped rate.

GREENVILLE, SOUTH CAROLINA 29609 p, r? 71 0 Winston Salem Drainage Study Hanes Commons Shopping Center Hanes Mall Blvd. neat to Lowes Forsyth County, N.C. DRAINAGE STUDY AND WATER QUALITY REPORT The following is the drainage study for the proposed Hanes Commons Shopping Center to be built along Hanes Mall Blvd. across from the existing Home Depot and south of the existing Lowes Store. The site is being proposed to be developed to contain a +/- 148,000 s.f. Costco Store, two 30,000 s.f. "mini-anchors", a 6,400 s.f restaurant, a 5000 s.f restaurant, and various shops space totaling 46,100 s.f. There is also off-site runoff that 1b will drain on to the site, although a large portion of the off-site runoff from the Lowes site and Hanes Mall Blvd. will be routed around the site. The report includes determination of required pond size for water quality as well as quantity. The pond will be analyzed based upon the 10 year and 25 year storm, as well as for water quality standards. The existing stormwater system along Hanes Mall Blvd. will be utilized to take the runoff from the pond as this is where the current runoff pattern lies. All runoff from the developed site will be directed to the proposed pond located in the western front corner of the site. The new pond will be sized to handle the first 1" of runoff and release it over a 48 hour period, the 2, 10, and 25 year storm events and restrict these storm events to the pre-developed rates. The pond will have a staged outlet to manage each storm. The 100 year storm event will overtop the outlet structure but will not overtop the pond. The stormwater runoff calculations shown in this report are based on the SCS TR-55 Method as required by the State of North Carolina and the City of Winston Salem. The runoff numbers and hydrographs are included. 0 a 0 Existing Conditions: The property is divided into three major drainage areas. The first is on the eastern side and leads from south to north towards Hanes Mall Blvd. The runoff drains through wooded areas and eventually into an existing channel that flows north to Hanes Mall Blvd. From there the runoff enters a 54" pipe and is conveyed down the road to an existing creek. This drainage area also picks up the runoff from the Lowes Store on the east side and a portion of Hanes Mall Blvd. The runoff from Lowes and the road will not be affected by the new development as it will be piped around the system. The second drainage area encompasses the "middle" of the site and takes in most of the proposed development area. There is also an area of off-site drainage to the south of the site that flows through this section and will continue to flow through in the developed state. Again, the flow sheets through wooded areas into an existing channel and ultimately to a 42" culvert at Hanes Mall Blvd. The last drainage area is a small section in the southwest corner that drains south and west off the property into a completely separate drainage basin. This area will not be affected by the development. The total site is +/- 40.0 acres with areas of off-site drainage coming onto the property. Slopes on the property vary but in general the site slopes from south to north. The bulk of the slopes are 10% and get somewhat flatter in areas in and around the creek. Soil types consist of type "B" soils as defined in the TR-55 manual and the Handbook on Erosion Control design as issued by the state. These soils are mostly clays and sands with small elements of loam and loamy sands. These soils are well drained, are moderately permeable and have a medium capacity for water. Surface runoff is generally rapid to very rapid. The closest body of water to the site is "Little Creek" located north and west of the property that leads west. Wetlands described as waters of the United States (creeks) are present on the site. These wetlands areas have been approved by the State of North Carolina and U. S. Corps of Engineers to be impacted by this development. However, the mitigation plan has not been finalized. 0 0 Developed Conditions: In the developed condition the site will be used for commercial development. This will consist of several "big box" users. There will also be smaller shops spaces available that may total 46,100 s. f. The development will include a field of parking, stormdrain system, and all accompanying utilities. The developed condition will also include the installation of a stormwater pond to control both quantity and quality of runoff that leaves the site. The pond has been sized to meet both the State of North Carolina requirements and the City of Winston Salem Requirements. a 0 0 0 Runoff Calculations: Existing Conditions: The runoff for both the existing and developed condition will be calculated using the TR- 55 Method. This method considers land use, time of travel for runoff, and rainfall events as prescribed by the US National Weather Service for this particular area, and the size of the area to determine stormwater runoff. The rainfall amounts will vary based on the design storm and these numbers are taken from the precipitation maps issued by the U. S. National Weather Service. The area is also analyzed to determine its current land use and a Runoff Curve Number is then generated for the site. Next the time of concentration (travel in minutes) of the runoff from the most remote point of the drainage basin to the outlet point is determined and these items are used in the calculations to determine the runoff Q. Runoff Curve Number : The runoff curve number is based on land use for each area and the percent of the area with that type of use. For example, pavement has a runoff number of 98 as it is almost entirely made up of impervious area. This number also takes into account the soil type as determined by the Soil Conservation Service. The soils are then classified as type AB, C & D which each have varying rates at which water runs off. This site is comprised of mostly Type B soils. Since the majority of this site is one use type we will use this CN number the entire site which will give us a more conservative design. Again, due to the stormwater management pond for Lowe's being installed after the first expansion, we will consider the existing condition to be the condition prior to the first expansion. This would include 5.00 acres of pavement and roof. The CN for this use is as follows. Area #1- 14.43 Area # 2 - 24.66 acres,Woods & acres, Woods & Grass (type B soils) Roof (type B'soils) CN = 56 CN = 55 0 Time of Concentration: The time of concentration for the existing drainage area will be calculated using three types of flow. Sheet flow for flow overland, not in a defined channel, Shallow Concentrated flow for any sheet flow after 300 feet assuming that the flow has concentrated somewhat, 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. For Sheet Flow the T = {0.007(nL)110.8)/P^0.5 s^0.4 and for shallow concentrated flow the time is based on the velocity and .the length per Fig. 3-1 from TR-55. The Open Channel time is based and the velocity from Manning's equation and this velocity is divided into the length a I D to get the time. All of this information is fed into the TR-55 computer program and the Tc is as follows for each area: Area #I First 300 ft. Sheet Flow @ 7.33% slope, Wooded Next 360 ft. Shallow Conc. Flow @ 10.3%Q slope, 111-. A-A Next 830 ft. Opoen Channel Flow @ 4.0 ft!s The total Tc is; Tc = 34.2 min. Area # 2 First' 300 ft. Sheet Next 360 ft. Shallow Next 830 ft. Open Flow @ 7.33% Conc. Flow'@ Channel Flow@ 4.0 slope, Wooded 10.3% slope, ft/s Wooded The total Tc is; Tc = 34.8 min. D Rainfall From the U.S. National Weather Service maps the rainfall amounts can be determined. These maps show the rainfall amounts for various design storms (i.e. 2, 10, 100 yr.) with the totals being in inches. These are derived for Forsythe County and the various storms are as follows: 2 yr. - 3.5 in. 10 yr.-5.0in 25 yr. - 6.0 in. 100 yr. - 7.2 in. This is based on a "Type II" storm as defined by SCS. Runoff Calculations b P Per the TR-55 Method the runoff will be calculated for the existing condition and a hydrograph will be generated for this runoff showing Q vs. time. This will be done for the 2 year and 10 year storm events. The results are as follows: Pre Developed Area #I Pre-Developed Rainfall Runoff. Storm Event in cfs 2 year 3.5 in 2.34 cfs 10 year 5.0 9.75 cfs 25 year 6.0 16.52 cfs 100 year 7.0 in 25.78 cfs Pre Developed Area #2 Pre-Developed Rainfall Runoff Storm Event Q in cfs 2 year 3.5 in 3.36 cfs 10 year 5.0 15.31 cfs 25 year 6.0 26.52 cfs 100 year 7.0 in 42.05 cfs The runoff from area 2 will be combined with the off-site runoff to the rear of the proposed development to get the total pre-developed runoff from area 2.

Rainfall The rainfall from the U.S. National Weather Service (as stated above) are as follows: 2 yr. - 3.50 in 25 yr. - 6.0 in 100 yr. - 7.20 in 0 D 0 0 Runoff Calculations Per the TR-55 Method the runoff will be calculated for the existing condition and a hydrograph will be generated for this runoff showing Q vs. time. This will be done for the 2 year, 10 year, 25 year, and 100 year storm events. The results are as follows: Post Developed Rainfall Rate Runoff cfs Storm Event in cfs 2 year 3.5 in 69.64 cfs 10 year 5.0 in 114.43 cfs 25 year 6.0 in. 144.79 cfs 100 year 7.2 in 181.38 cfs These numbers will be used to develop hydrographs through the pond. 0 'Pos-r -D avs )a ?Oklp 10 - Combine - 2 Yr - Qp = 69.64 cfs v C? 0 Time (hrs) / Hyd. 3 / Hyd. 4 / Hyd. 10 0 0 5 10 15 20 25 N 9 0 10 - Combine - 25 Yr - Qp = 144.79 cfs 150 i Hyd. 3 100 j V C'1 ? j /Hyd. 4 50 I , I I Hyd. 10 o 0 5 10 15 20 25 Time (hrs) 0 10 - Combine -100 Yr - Qp = 181.38 cfs 2 1 C1 Time (hrs) Hyd. 3 / Hyd. 4 / Hyd. 10 0 0 5 10 15 20 25 0 POND SIZING AND ROUTING The required pond sizing as stated earlier will be based on water quantity requirements and water quality requirements. The required quantity is based on the 1" of runoff being stored and released over a 48 hour period, and storing and releasing the 2 year and 25 year storms at their pre-developed rates. The quality storage will be provided by supplying a defined storage area (in square feet) as determined by the depth of the permanent pool and the surface area to drainage area ratio. The pond will be a surface pond with a.bottom elevation of 766.0, a permanent pool elevation off 772.0, and a top elevation of 780.75. Based on the proposed depth of 6 feet, the required surface area for the 38.2 acre drainage area is 32,781 s.f. The surface area 9 provided at elevation 772.0 is 35,575 s.f. Based on these requirements we have sized the outlet to release the runoff at the various stages. The resulting outlet will have to release runoff to the two existing culverts on Hanes Mall Blvd. For this reason there will actually be two outlets for the pond, each sized for the individual pre-developed areas. To release point `A' the outlet will have a 2.72" orifice. This will be accomplished with the use of a 2 '/2" pvc pipe at elevation 772.0 that will elbow down into the permanent pool. The 2 year storm will be released through an orifice. The orifice will be 7.0" in diameter placed at the top of the 1" storage (el. 774.37). The 25 year storm will be release via a weir at the top of the 2 year storage elevation. This weir will be 0.7' in length at elevation 776.7. The 100 year storm will overtop the riser and exit through the outlet pipe. For the release to Point "B' the outlet will have the same 2 '/2" pvc pipe. The 2 year release will be through an orifice placed at the top of the 1" storage (el. 774.37). The orifice will be 15" in diameter. The 25 year storm will be released through a weir at the top of the 2 year storage elevation. The weir will be 1.40 feet in length. Again, the 100 year storm will overtop the riser and exit through the outlet pipe. Refer to the calculations included for more details of required volumes. The outlet pipes from each riser are sized as follows; Manning's Equation - Q= 1.49/n x A x R^2/3 X S^1/2 From.this equation it is determined that the required pipe size for each outlet will be 42". Refer to the hydrographs for reservoir routing showing storage elevations, release rates, etc.. The results are as follows: POND Stage Storage Volume Allowable Release Actual Release First 1" 774.37 101,930 0.6 cfs 0.6 cfs 2 . 776.70 191,781 cf 10.67 cfs 10.30 cfs 25 . 779.97 349,550 cf 57.68 cfs 57.00 cfs 100 yr. 780.69 386,103 cf N/a 116.33 cfs 0 As can be seen in the above table the release rate from the pond for the 2 yr. and 25 yr. storm events is below the allowable release rates in the pre-developed condition.

Since you propose to impact greater than 150 linear feet of perennial streams, compensatory stream mitigation will be required in accordance with 15A NCAC 2H.0506(h). You have the following options for satisfying the mitigation requirement associated with this project: 1. Payment into the North Carolina Wetland Restoration Program, if the WRP will accept the responsibility for conducting this mitigation work, or 2. Preparing and implementing a stream mitigation plan. In your original application, you proposed using the WRP for stream mitigation. Please contact Mr. Ron Ferrell, supervisor of the Wetland Restoration Program, at 919-733-5208. We must receive written concurrence from the WRP that they are prepared to locate and implement a stream mitigation site for your project. If you decide to develop a stream mitigation site at another location, your application will be considered incomplete until a mitigation plan is forwarded to this office. Also, please provide details for the stormwater pond referenced in your application. It will be helpful to review the calculations used to determine the size of the pond so that we can conclude whether or not it will be adequate. Until this information is received, I will request (by copy of this letter) that the Corps of Engineers place this project on hold. Also, this project will be placed on hold for our processing due to incomplete information (15A NCAC 2H.0507(h)). I can be reached at (919) 733-1786.

Environmental Consultants April 13, 2000 Mr. S. Kenneth Jolly US Army Corps of Engineers 6508 Falls of the Neuse Road, Suite 120 Raleigh, North Carolina 27615 APR Re: Winston-Salem Site, ID 200020130 Winston-Salem, North Carolina Applicant: Mr. Donald W. Garner Isakson-Barnhart 25 Technology Parkway South, Suite 201 Norcross, Georgia 30092 c000 On behalf of our client, Williamsburg Environmental Group, Inc. (WEG) is pleased to provide the following additional information, as you requested in your letter of March 13, 2000.. The enclosed material presents an overview of the alternatives considered for this project and highlights the efforts taken to minimize impacts to waters and wetlands within the proposed development. Isakson-Barnhart, the applicant for the 35-acre Winston-Salem Site, is proposing a commercial retail center involving the construction of road infrastructure, utility line installation, and commercial retail development. The purpose of the project is to create a quality retail shopping complex that satisfies the market sector demands of the retail merchants. proposing to utilize this facility. Prior to focusing their effort within the proposed 35-acre site, the project proponents evaluated two additional sites within the service area surrounding Hanes Mall (Figure 1). Available sites located out of this service area were considered and rejected early in the process since they were too far from the Hanes Mall area to support the commercial aspect of this project. The major retail tenants, such as the ones wanting to use this development, require that the site be located within the immediate shopping area of a regional commerce center. They require the project to be located on a major roadway and at a major intersection with traffic control. In addition, the specific requirements. of the proposed tenants dictate that the development contain other national tenants to provide the synergy and customer volume necessary to support this commercial venture. There is only one other tract of land in the Hanes Mall area large enough for this type of development. The property is located on Hanes Mall Boulevard adjacent to Interstate 40. Although the property occupies 53 acres, it is not located at a major intersection with traffic control and it has limited buildable area due to a sewer easement that bisects the property at an angle. This would greatly reduce the number of large tenant stores that could locate on the property without which there would not be enough income producing area to provide for an economically successful development. The core anchor for the proposed development has confirmed they would not locate in this location. This site also contains environmental 3000 Easter Circle Williamsburg, Virginia 23188 (757) 220-6869 FAX (757) 229-4507 Mr. S. Kenneth Jolly April 13, 2000 Page 2 constraints similar to if not greater than those found on the proposed site. The property is bisected by a downstream segment of the same waterway found on the current site and due to its location on the property would require greater impacts to jurisdictional resources should the site be developed under the proposed use. The site is also significantly below the roadway elevation. It would not be economically feasible to raise the building grades to the road elevation. As such, this alternative would leave the buildings in a hole, which is unacceptable. As a result of a, combination of these factors, this site was rejected from further consideration. There is a second property located on Hanes Mall Boulevard that was considered and rejected. This 22-acre parcel is located across from the 53-acre tract and is currently not for sale. The. property is also critically constrained by the Duke Power high voltage transmission lines. Such a constraint restricts the actual buildable. area on the property rendering it too small for the proposed development. No other properties-were found in this area which meet the requirements of the proposed tenants. Once a decision was made to focus on the proposed location, a considerable effort was made to arrive at commercial layout that avoids and minimizes impacts to jurisdictional resources to the greatest extent practicable. Several alternative layouts were examined in an effort to reduce impacts. A representative composite of these alternatives was presented as Alternative #1 in the application document. However, numerous iterations of similar layouts were considered in an effort to decrease the footprint within the resource areas. All of these alternatives sought to minimize impacts with particular attention paid to the stream section designated as Area II on.the project drawings. These alternatives (A through C) were developed to examine the practicability of alternative development configurations given other site constraints, zoning requirements, tenant needs, and the economic requirements of the investors. Alternative A eliminates the majority of the commercial area along Hanes Mall Boulevard. This layout is contrary to the requirement of the neighborhood association that adjoins this project to the rear and the City of Winston-Salem. It violates the concept of staging development as one moves away from the roadway such that the large anchor stores do not dominate the landscape in the immediate vicinity of the roadway. The small retail stores need to be located along Hanes Mall Boulevard while the larger box stores are located to the rear of the development. This alternative also does not meet the parking requirement of the City of Winston-Salem and the retail tenants, which require a certain number of parking spaces before agreeing to locate in a development. This plan has only 1024 parking spaces while the requirement is 1429 spaces. There is not enough room to provide more parking without further impacting jurisdictional resources. This alternative also contains a major flaw in that the applicant cannot locate smaller retail development under the Duke Power high voltage lines. The equity partners and the lender require a certain return on their investment. The elimination of small retail stores would bring the return below acceptable levels. Alternative B sought to investigate the impact of removing the retail area from under the power lines while still minimizing impacts to jurisdictional areas. However, many of the same constraints that plagued the previous alternative remain under this scenario. The parking requirement has not been met, the commercial area has been reduced further impacting the return Mr. S. Kenneth Jolly April 13, 2000 Page 3 on investment, and the service center associated with the major tenant has been eliminated. The elimination of this facility is not acceptable to them since it represents a significant component of their overall business plan. The parking requirement for this alternative is .1413 spaces and only 1151 can be provided. In addition, all of the retail stores going into this development require storefront parking. There is not enough room available in front of the stores to provide this required area. In order to satisfy this requirement, the detention pond would have to be relocated within the same creek we sought to avoid. Alternative C was developed to examine. the practicality of. expanding the retail component outside of jurisdictional areas in an effort to satisfy the economic constraints of the investors and site configuration requirements imposed by the tenants. While this configuration does replace the service center in the northern portion of the project, the overall retail area is decreased. The parking, requirement of 1308 spaces for this layout is not met and the direct access to the rear of the development has been removed. This rear access is a requirement of the neighborhood association, the City of Winston-Salem, and the property owner to keep this area from being landlocked. The landowner cannot provide internal access to the rear parcel through an existing residential road network. This parcel needs to have direct access off of Hanes Mall Boulevard through the proposed development. In addition, the location of small retail stores at a 90-degree angle to Hanes Mall Boulevard is unacceptable. Small. retailers such as these require visibility for their economic. success. This location would greatly reduce such visibility due the grade differences and the linear distance from the roadway. In summary, the applicant has investigated both offsite locations and onsite development configurations in an effort to reduce impacts to jurisdictional resources. However, given the site constraints, economic constraints, tenant needs and local requirements, it is our opinion that the selection and development of this property represents the most viable and least environmentally damaging practicable alternative for this project. In your letter you also requested that the applicant include a mitigation proposal to offset the unavoidable impacts to jurisdictional waters and wetlands. The original permit support document submitted last fall proposed to mitigate for the unavoidable impacts to 867 linear feet of stream channel (Area II), 0.32 acres of nontidal forested-headwater wetlands and 0.07 acres of other waters of the U.S. (Area 1). The applicant investigated various compensation options including onsite creation, offsite creation, and offsite preservation of significant or sensitive aquatic/wetland environments. The 0.07 acres of waters impacted in Area I should be adequately compensated thought the creation 40,538 S.F. of ponded surface area within the proposed BMP. A 10-foot vegetated wetland bench is also proposed within this BMP. Onsite creation of wetlands, however, is not feasible due to the limited project size and severe topography. A wetland creation ratio of 2:1 would require the excavation and planting of approximately 0.64 acres of forested wetlands and the creation of 867 linear feet of stream channel. This project site will not support any kind of commercial development and such a mitigation compensation site. A review of adjacent properties revealed that most uplands are either developed or are in the process of developing. In addition, no disturbed offsite areas in the vicinity were determined to be suitable for wetland restoration or creation. As such, the applicant proposes to make a Mr. S. Kenneth Jolly April 13, 2000 Page 4 contribution to the Wetlands Restoration Program (WRP) in the amount of $123,735.00 (867 l.f x $125.00 + 0.64 acres x $24,000), subject to Corps and NCDENR approval. On behalf of our client, the Williamsburg Environmental Group, Inc. respectfully requests that the Corps proceed with the processing of this permit. I have also included a copy of the pipeline routing plan as requested by Mr. John Thomas. If you have any questions, please feel free to call me at your convenience.

The proposed new construction site is located off of Hanes Mall Boulevard, in Winston-Salem, Forsyth County, North Carolina. Your receipt of this letter verifies your acceptance of a valid request for certification in accordance with Section 325.2(b)(ii) of our administrative regulations. We are considering authorizing the proposed activity pursuant to Section 404 of the Clean Water Act, and we have determined that a water quality certification is required under the provisions of Section 401 of the same law. A Department of the Army permit will not be granted until the certification has been obtained or waived. In accordance with our administrative regulations, in most cases, 60 days after receipt of a request for certification is a reasonable time for State action.

Nature of Activity (Description of project, include all features) The applicant for the 35-acre site is proposing a commercial retail center involving the construction of approximately 300,000 square feet of commercial retail space, associated access roads, and a required stormwater management facility. The site is divided into two small drainages. The western drainage (Area 1) consists of an intermittent stream/forested-headwater wetland with and onsite drainage area of 14 acres and an offsite drainage area of 8 acres. Drainage within this area flows into a 42-inch culvert under Hanes Mall Blvd. The eastern drainage (Area II) is somewhat larger with an onsite area of approx. 25 acres and an offsite drainage area of approx. 10 acres. Drainage within this section enters the property from two existing culverts and exists the project through a 64-inch culvert under Hanes Mall Blvd. Neither of these waters is classified a critical resources waters of trout waters. 19. Project Purpose (Describe the reason or purpose of the project, see instructions) The project involves commercial development within a section of Hanes Mall Boulevard that has and continues to experience ongoing commercial development The project's location makes this site desirable for commercial users who want to locate in this particular location adjacent to existing roadway infrastructure and existing commercial enterprises. USE BLOCKS 20-22 IF DREDGED AND/OR FILL MATERIAL IS TO BE DISCHARGED 20. Reason(s) for Discharge A discharge into waters of the United States is required in order to meet the projects purpose and provide sufficient water quality treatment in the proposed stormwater management facility. The site is severely constrained by existing topography and resource areas within the northern portion of the site. In examining practicable development scenarios, the applicant evaluated the potential for avoidance of these resource areas within the context of the project goals and objectives. The option of reducing commercial area was also investigated. This option, however, was ultimately eliminated from consideration due to economic reasons. The projects location directly along the Hanes Mall Boulevard corridor makes this property highly desirable commercial real estate. Further decreasing the amount of proposed building square footage is not possible due to the applicant's need to make an acceptable return on investment 21. Type(s) of Material Being Discharged and the Amount of Each Type in Cubic Yards Native soil will be utilized as a source of fill material. The applicant will make every effort to balance the earthworks onsite. area of Acres of Wetlands or Other Waters Filled (See Instructions) The project involves permanent impacts to 0.32 acres of wetlands and 0.23 acres (867 linear feet) of other waters of the United States. 23.

Moreover, if they were able to decrease that impact to less that 150 LF (remove the traffic islands at th IIQ?I? at that point). they would not be reauired to mitigate. (The project immediately downstream (Michael Neill prQ.- .

Coble NCDENR-DWQ Winston-Salem Regional Office 585 Waughtown Street Winston-Salem, NC 27107 Re: DWQ Application # 99-1172 Winston-Salem Site Additional Information Dear Mr. Coble: On behalf of our client, Williamsburg Environmental Group, Inc. (WEG) is pleased to provide the following information, per your request of November 4, 1999. The information is itemized to correspond to your letter. 1) Since the proposed impacts are greater than 500 linear feet, please contact the USACOE for instructions regarding applying for an Individual Permit. We have coordinated with the Corps regarding an Individual Permit application. Enclosed please find a copy of our correspondence to the Corps including the application. 2) Please include the impacts to all jurisdictional waters. I spoke with Mr. John Thomas regarding the jurisdictional determination that was approved in August of 1995. Since I was not personally involved in the determination at that time, I had to rely on Mr. Thomas for clarification on this point. His response to me was that as long as the existing determination is valid, the limits of jurisdictional area are defined by the mapping that was confirmed at that time. As such, he felt it inappropriate to modify the delineation. 3) For Area I, the USACOE called this drainage jurisdictional waters with a square footage requirement. However, NCDENR-DWQ utilizes only linear footage for stream channels (mitigatable or not). Therefore, for sections of this channel noted as "waters impact", please determine the linear footage of impact. The project drawings have been revised to reflect the change requested. 4) If the delineated wetland in Area III (0.02acres) is to be impacted and the Corps determined it jurisdictional, please include this with the total acreage of impact. The wetland area identified on the jurisdictional determination as Area III is not a part of the proposed project. No wetland impacts are proposed in this area. 3000 Easter Circle Williamsburg, Virginia 23188 (757) 220-6869 FAX (757) 229-4507 Mr. Larry D. Coble January 27, 2000 Page 2 S) It is mentioned in your application that "...no disturbed offsite areas were determined to be suitable for wetland restoration or creation. " Please provide documentation as to how and where sites were invested and why they are not suitable. WEG evaluated the area along the backside of the property associated with Area III for potential mitigation. While this property adjoins the project area it is not a part of the project. Its landscape position is somewhat higher and has a limited drainage area. . For surface water driven wetland compensation, our experience indicates a need for considerable surface area drainage to support the compensation area. In our opinion, this site's higher landscape position and limited drainage area exclude this site as a potential mitigation site. Unfortunately, the applicant does not have access to any additional sites in the project area. WEG also evaluated a stream channel alignment change to restore onsite, all or a portion of, the stream channel that is proposed to be impacted. We evaluated alignments through the project, along the northern perimeter adjacent to Hanes Mall Boulevard, and along the western perimeter. None of these alternatives were determined to be engineeringly viable due to the topography of the site. WEG continues to support and recommend onsite mitigation when and where opportunities exist. We also realize, however, what others have come to question, that fragmented, piecemeal compensation can have reduced functional value and an increased likelihood of failure. Hence, in this instance, we recommended a contribution to the Wetlands Restoration Program where these dollars could be leveraged with other resources for larger environmental gains. In addition, the practicability of this project is directly related to the project's location and visibility situated adjacent to existing commercial areas along a major thoroughfare. It is my understanding from discussions with the Corps and NCDENR staff that the proposed development of this site is consistent with other permit actions in the immediate vicinity. We hope that this submittal answers all of your questions. We apologize for the delay in our response. We were coordinating the Corps on the best direction to take this application considering the anticipated changes to the Nationwide Permit program. If we can provide any additional information, please do not hesitate to call me. Sincerely, Charles R.

Garner Isakson-Barnhart 25 Technology Parkway South, Suite 201 Norcross, Georgia 30092 This correspondence will follow up our discussions regarding the application submitted to you last fall for the development of a site located in Winston-Salem, North Carolina. Enclosed please find the application you requested along with the list of adjoining property owners and certification of the list from Forsyth County. I have also included a revised set of project drawings in both full size and 8.5 " x 11" format. Please append this material to the permit support document that was submitted with the original application. The only changes to the drawings are in the accounting for impacts to waters of the United States. The North Carolina Department of Environment and Natural Resources (NCDENR) requested the linear footage on waters in Area I of the project site. I apologize for the delay in responding to your request but based on our conversation regarding the pending changes in the Nationwide Permit (NWP) program, we were in somewhat of a quandary as to how to proceed. It is our understanding that under the new permits, the proposed impacts could be authorized by a Nationwide Permit. The scheduling delays that have plagued the effective date of the proposed changes, however, have caused us to proceed with the individual permit process at this time. It is my understanding, based on our conversation, that should the new NWP's become effective during the application review, my client has the option of withdrawing this application and requesting that it be considered under the new NWP program. On behalf of our client, the Williamsburg Environmental Group, Inc. (WEG) respectfully requests that the Corps process this application. If you have any questions, please feel free to call me at your convenience. Thank you for your consideration in this matter. Sincerely, Charles R.

OTHER LOCATION DESCRIPTIONS, IF KNOWN (seeinstruc6ons) Hanes Mall Boulevard, Immediately adjacent to Lowe's Home Center 17. DIRECTIONS TO THE SITE From the intersection of Stafford Road and Hanes Mall Boulevard, travel wet on Hanes Mall Boulevard approximately 1/8 mile. Subject property is located adjacent to Lowe's Home Center. J ENG. FORM 4345, Feb 94 EDITION OF SEP 91 IS OBSOLETE. (Proponent: CECW-OR) 18. Nature of Activity (Description of project, include all features) The applicant for the 35-acre site is proposing a commercial retail center involving the construction of approximately 300,000 square feet of commercial retail space, associated access roads, and a required stormwater management facility. The site is divided into two small drainages. The western drainage (Area 1) consists of an intermittent stream/forested-headwater wetland with and onsite drainage area of 14 acres and an offsite drainage area of 8 acres. Drainage within this area flows into a 42-inch culvert under Hanes Mail Blvd. The eastern drainage (Area 11) is somewhat larger with an onsite area of approx. 25 acres and an offsite drainage area of approx. 10 acres. Drainage within this section enters the property from two existing culverts and exists the project through a 54-inch culvert under Hanes Mall Blvd. Neither of these waters is classified a critical resources waters of trout waters. 19. Project Purpose (Describe the reason or purpose of the project, see instructions) The project involves commercial development within a section of Hanes Mall Boulevard that has and continues to experience ongoing commercial development The project's location makes this site desirable for commercial users who want to locate in this particular location adjacent to existing roadway infrastructure and existing commercial enterprises. USE BLOCKS 20-22 IF DREDGED AND/OR FILL MATERIAL IS TO BE DISCHARGED 20. Reason(s) for Discharge A discharge into waters of the United States is required in order to meet the projects purpose and provide sufficient water quality treatment in the proposed stormwater management facility. The site is severely constrained by existing topography and resource areas within the northern portion of the site. In examining practicable development scenarios, the applicant evaluated the potential for avoidance of these resource areas within the context of the project goals and objectives. The option of reducing commercial area was also investigated. This option, however, was ultimately eliminated from consideration due to economic reasons. The projects location directly along the Hanes Mall Boulevard corridor makes this property highly desirable commercial real estate. Further decreasing the amount of proposed building square footage is not possible due to the applicant's need to make an acceptable return on investment 21. Type(s) of Material Being Discharged and the Amount of Each Type in Cubic Yards Native soil will be utilized as a source of fill material. The applicant will make every effort to balance the earthworks onsite. 22. Surface area of Acres of Wetlands or Other Waters Filled (See Instructions) The project involves permanent impacts to 0.32 acres of wetlands and 0.23 acres (867 linear feet) of other waters of the United States. 23. Is any portion of the Work Already Complete? Yes No X IF YES, DESCRIBE THE COMPLETED WORK 24.

Coble NCDENR-DWQ Winston-Salem Regional Office 585 Waughtown Street Winston-Salem, NC 27107 Re: DWQ Application # 99-1172 Winston-Salem Site Additional Information Dear Mr. Coble: On behalf of our client, Williamsburg Environmental Group, Inc. (WEG) is pleased to provide the following information, per your request of November 4, 1999. The information is itemized to correspond to your letter. 1) Since the proposed impacts are greater than 5001inear feet, please contact the USACOE for instructions regarding applying for an Individual Permit. We have coordinated with the Corps regarding an Individual Permit application. Enclosed please find a copy of our correspondence to the Corps including the application. 2) Please include the impacts to all jurisdictional waters. I spoke with Mr. John Thomas regarding the jurisdictional determination that was approved in August of 1995. Since I was not personally involved in the determination at that time, I had to rely on Mr. Thomas for clarification on this point. His response to me was that as long as the existing determination is valid, the limits of jurisdictional area are defined by the mapping that was confirmed at that time. As such, he felt it inappropriate to modify the delineation. 3) For Area I, the USACOE called this drainage jurisdictional waters with a square footage requirement. However, NCDENR-DWQ utilizes only linear footage for stream channels (mitigatable or not). Therefore, for sections of this channel noted as "waters impact", please determine the linear footage of impact. The project drawings have been revised to reflect the change requested. 4) If the delineated wetland in Area III (0.02acres) is to be impacted and the Corps determined it jurisdictional, please include this with the total acreage of impact. The wetland area identified on the jurisdictional determination as Area III is not a part of the proposed project. No wetland impacts are proposed in this area. 3000 Easter Circle Williamsburg, Virginia 23188 (757) 220-6869 FAX (757) 229-4507 t -# - Mr. Larry D. Coble January 27, 2000 Page 2 S) It is mentioned in your application that "...no disturbed offsite areas were determined to be suitable for wetland restoration or creation. " Please provide documentation as to how and where sites were invested and why they are not suitable. WEG evaluated the area along the backside of the property associated with Area III for potential mitigation. While this property adjoins the project area it is not a part of the project. Its landscape position is somewhat higher and has a limited drainage area. For surface water driven wetland compensation, our experience indicates a need for considerable surface area drainage to support the compensation area. In our opinion, this site's higher landscape position and limited drainage area exclude this site as a potential mitigation site. Unfortunately, the applicant does not have access to any additional sites in the project area. WEG also evaluated a stream channel alignment change to restore onsite, all or a portion of, the stream channel that is proposed to be impacted. We evaluated alignments through the project, along the northern perimeter adjacent to Hanes Mall Boulevard, and along the western perimeter. None of these alternatives were determined to be engineeringly viable due to the topography of the site. WEG continues to support and recommend onsite mitigation when and where opportunities exist. We also realize, however, what others have come to question, that fragmented, piecemeal compensation can have reduced functional value and an increased likelihood of failure. Hence, in this instance, we recommended a contribution to the Wetlands Restoration Program where these dollars could be leveraged with other resources for larger environmental gains. In addition, the practicability of this project is directly related to the project's location and visibility situated adjacent to existing commercial areas along a major thoroughfare. It is my understanding from discussions with the Corps and NCDENR staff that the proposed development of this site is consistent with other permit actions in the immediate vicinity. We hope that this submittal answers all of your questions. We apologize for the delay in our response. We were coordinating the Corps on the best direction to take this application considering the anticipated changes to the Nationwide Permit program. If we can provide any additional information, please do not hesitate to call me. Sincerely, Charles R.

Garner Isakson-Barnhart 25 Technology Parkway South, Suite 201 Norcross, Georgia 30092 Environmental Consultants This correspondence will follow up our discussions regarding the application submitted to you last fall for the development of a site located in Winston-Salem, North Carolina. Enclosed please find the application you requested along with the list of adjoining property owners and certification of the list from Forsyth County. I have also included a revised set of project drawings in both full size and 8.5 " x I V format. Please append this material to the permit support document that was submitted with the original application. The only changes to the drawings are in the accounting for impacts to waters of the United States. The North Carolina Department of Environment and Natural Resources (NCDENR) requested the linear footage on waters in Area I of the project site. I apologize for the delay in responding to your request but based on our conversation regarding the pending changes in the Nationwide Permit (NWP) program, we were in somewhat of a quandary as to how to proceed. It is our understanding that under the new permits, the proposed impacts could be authorized by a Nationwide Permit. The scheduling delays that have plagued the effective date of the proposed changes, however, have caused us to proceed with the individual permit process at this time. It is my understanding, based on our conversation, that should the new NWP's become effective during the application review, my client has the option of withdrawing this application and requesting that it be considered under the new NWP program. On behalf of our client, the Williamsburg Environmental Group, Inc. (WEG) respectfully requests that the Corps process this application. If you have any questions, please feel free to call me at your convenience. Thank you for your consideration in this matter. Sincerely,oadle Charles R.

OTHER LOCATION DESCRIPTIONS, IF KNOWN (see instructions) Hanes Mall Boulevard, Immediately adjacent to Lowe's Home Center 17. DIRECTIONS TO THE SITE From the intersection of Stafford Road and Hanes Mall Boulevard, travel wet on Hanes Mall Boulevard approximately 1/8 mile. Subject property is located adjacent to Lowe's Home Center. ENG. FORM 4345. Feb 94 EDITION OF SEP 91 IS OBSOLETE. (Proponent: CECW-OR) 18. Nature of Activity (Description of project, include all features) The applicant for the 35-acre site is proposing a commercial retail center involving the construction of approximately 300,000 square feet of commercial retail space, associated access roads, and a required stormwater management facility. The site is divided into two small drainages. The western drainage (Area 1) consists of an intermittent stream/forested-headwater wetland with and onsite drainage area of 14 acres and an offsite drainage area of 8 acres. Drainage within this area flows into a 42-inch culvert under Hanes Mall Blvd. The eastern drainage (Area 11) is somewhat larger with an onsite area of approx. 25 acres and an offsite drainage area of approx. 10 acres. Drainage within this section enters the property from two existing culverts and exists the project through a 64-inch culvert under Hanes Mall Blvd. Neither of these waters is classified a critical resources waters of trout waters. 19. Project Purpose (Describe the reason or purpose of the project, see instructions) The project involves commercial development within a section of Hanes Mall Boulevard that has and continues to experience ongoing commercial development The project's location makes this site desirable for commercial users who want to locate in this particular location adjacent to existing roadway infrastructure and existing commercial enterprises. USE BLOCKS 20-22 IF DREDGED AND/OR FILL MATERIAL IS TO BE DISCHARGED Reason(s) for Discharge A discharge into waters of the United States is required in order to meet the projects purpose and provide sufficient water quality treatment in the proposed stormwater management facility. The site is severely constrained by existing topography and resource areas within the northern portion of the site. In examining practicable development scenarios, the applicant evaluated the potential for avoidance of these resource areas within the context of the project goals and objectives. The option of reducing commercial area was also investigated. This option, however, was ultimately eliminated from consideration due to economic reasons. The projects location directly along the Hanes Mall Boulevard corridor makes this property highly desirable commercial real estate. Further decreasing the amount of proposed building square footage is not possible due to the applicant's need to make an acceptable return on investment. 21. Type(s) of Material Being Discharged and the Amount of Each Type in Cubic Yards Native soil will be utilized as a source of fill material. The applicant will make every effort to balance the earthworks onsite. 22. Surface area of Acres of Wetlands or Other Waters Filled (See instructions) The project involves permanent impacts to 0.32 acres of wetlands and 0.23 acres (867 linear feet) of other waters of the United States. 23. Is any portion of the Work Already Complete? Yes No X IF YES, DESCRIBE THE COMPLETED WORK 24.

Insufficient evidence is present in our files to conclude that your project must be built as planned in waters and/or wetlands in accordance with 15A NCAC 2H .0506. Therefore, unless modifications of the proposal are made as described below, we will have to move toward denial of your 401 Certification as required by 15A NCAC 2H .0507(e) and will place this project on hold as incomplete until we receive this additional information. We are requesting (by copy of this letter) that the U.S. Army Corps of Engineers place your project on administrative hold.a v (1) Since the proposed impacts are greater that 500 linear feet, please A contact the USACOE for instructions regarding applying for an Individual Permit. (2) Please include the impacts to all jurisdictional waters. Specifically, the headwaters of the channel in Area II (from the Lowe's Parking Lot culvert downstream to the established knickpoint of the Duke Power lines) must be included as impact, even though mitigation is not required. It is also the understanding of this Office that, based on the 2/12/99 site visit, this area was to be delineated for the presence of riparian wetlands. Your wetland delineation map does not show if this area had been investigated for the presence of wetlands. (3) For Area I, the USACOE called this drainage jurisdictional waters with '.f a square footage requirement. However, NCDENR-DWQ utilizes only linear footage for stream channels (mitigatable or not). Therefore, for the sections of this channel r , noted as "waters impact", please determine the linear footage of impact.

Garner Isakson-Barnhart 25 Technology Parkway South, Suite 201 Norcross, Georgia 30092 This correspondence will follow up our on-site meeting in January 1999 at a proposed development site located in Winston=Salem, North Carolina. You may recall we visited the site to examine waterways present on the property. The enclosed application contains a permit support document with appendices, a wetlands confirmation, a stormwater management plan, relevant maps and correspondence. The construction of this development including the stormwater management facility will require direct impacts to 0.32 acres of nontidal-forested headwater wetlands, 0.07 acres of other waters of the U.S. and 867 linear feet of stream channel. The applicant has worked diligently to avoid and minimize impacts to natural resources to the greatest extent practicable, however in this instance, impacts to jurisdictional resources are unavoidable. In an effort to compensate for permanent unavoidable impacts to wetlands and stream channel, the applicant is proposing to mitigate these impacts through a contribution to the Wetlands Restoration Program (WRP). On behalf of our client, the. Williamsburg Environmental Group, Inc. (WEG) respectfully requests.that the Corps process this application. By copy of this correspondence, WEG also requests that the North Carolina Department of Environment and Natural Resources (NCDENR) process the application.

The proposed project is located in southwestern Winston- Salem, North Carolina (Figure 1-1) along the southern lane of Hanes Mall Boulevard (Figure 1- 2). The property is bordered by Lowe's Home Center to the east, Hanes Mall Boulevard to the north, residential development to the south, property currently under commercial development to the west. The proposed commercial development for this property has been carefully designed to integrate the development into the landscape while providing long-term protection to water quality. The plan calls for the construction of approximately 300,000 square feet of commercial space as well as the construction of associated road and utility infrastructure. Impacts are necessary in order to provide a suitable commercial pad and a required stormwater management facility. Impacts to jurisdictional waters of the U. S., including wetlands, have been examined in an effort to avoid and minimize these impacts to the maximum extent practicable while still meeting the project purpose. Development alternatives were investigated including total elimination of impacts, elimination of building square footage to minimize impacts, and redesign of the stormwater management facility. The applicant has worked to develop the site in a manner acceptable to the City of Winston Salem. In accordance with the regulatory agencies' procedures, Isakson-Barnhart, the applicant, is submitting this application for review and approval of the proposed development (Appendix A). This document has been prepared to accompany the application and provide more detail of the proposed project than is possible within the format of the application itself. 1 n J 0 n 1 i 7L== NO 2.4 MILES 12 0 MILES 1.4 MILES SCALE.

In order to facilitate the review of this project, an environmental characterization of the project area has been completed. This section provides a general environmental overview of the project area and specifically discusses environmental parameters that are pertinent to the permitting process. This section was written utilizing information from a variety of correspondence, reports, and studies including wetland investigations conducted by the Williamsburg Environmental Group, Inc. (WEG). 2.1 WATER RESOURCES Aquatic habitats present on the property consist primarily of palustrine forest associated with the headwater areas located within the Little Creek drainage basin. The water bodies situated within the immediate project area consist primarily of two nontidal headwater drainages that flow south to north into existing culverts under Hanes Mall Boulevard. The western drainage on the property (Area I) consists of an intermittent stream/forested-headwater wetland (Photo 1) with an on-site drainage area of approximately 14 acres and off-site drainage area of approximately 8 acres. Drainage within this area flows into a 42-inch culvert at Hanes Mall Boulevard (Photo 2). The eastern drainage (Area Il) is somewhat larger with an on-site drainage area of approximately 25 acres and off-site drainage area of approximately 10 acres (Photos 3 & 4). Drainage within this section of the project enters the property from two culverts, one under Hanes Mall Boulevard and a second culvert entering the property from the adjacent Lowe's Home Center. Waters with this drainage flow through the project area and into a 54-inch culvert ' under Hanes Mall Boulevard (Photo 5). Neither of these systems are classified as critical resource waters or trout waters. The stream segment within Area H has essentially been isolated ' by existing development on adjoining parcels. In addition, this development continues to degrade on-site resources and would be expected to continue even in the absence of the proposed development. This was made apparent with the erosion of 0.02 acres of wetlands within Area II since the site was confirmed in 1995 and the appearance of degraded stream conditions including ' eroding banks with exposed root material and evidence of increasing sediment deposition. n n n FIJI D t L F I r Jurisdictional waters of the U.S., including wetlands, present within the entire parcel were delineated by WEG ecologists in accordance with the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory, 1987). Wetland flags were placed in the field by WEG to provide an onsite record of the location of jurisdictional areas. The Corps confirmed this delineation on August 18, 1995. The jurisdictional limits are shown on the plans within Map Pocket A and the confirmation letter is included within Appendix B. Dominant vegetation within the forested wetlands includes red maple (Acer rubrum), sweetgum (Liquidambar styrac j7ua), green ash (Fraxinus pennsylvanica), and poison ivy (Toxicodendron radicans). 2.2 VEGETATION The project site,is situated within the Eastern Deciduous Forest Province as described by Gleason & Cronquist (1964). The mixed hardwood forest typical of this province is comprised of a diverse community, which contains over two dozen hardwood species, intermixed with stands of pine. Upland immature hardwood forests represent the majority of the vegetation community type in the project area, however, there are some scattered mature hardwoods. The most commonly occurring species in the subcanopy within this forest community included sweet gum (Liquidambar styraciflua), red maple (Acer rubrum), and tulip tree (Liriodendron tulipifera). Other accessory species of the subcanopy included sycamore (Platanus occidentalis), Virginia pine (Pinus virginiana) and green ash (Fraxinus pennsylvanica). The shrub layer consists of tree saplings in addition to common privet (Liqustrum vulgare) and dogwood (Corpus jlorida). The sparse herbaceous stratum of this community consists of Christmas fern (Polystichum acrostichoides), poison ivy (Toxicodendron radicans), Japanese honeysuckle (Lonicera japonica), greenbriar (Smilax sp.), Virginia creeper (Parthenocissus quinquefolia) and violet (Viola sp.). 1 2.3 WILDLIFE Wildlife is dependent upon the habitat in which they thrive. The vegetation communities discussed above provide habitat for a variety of wildlife species. Some of the wildlife species typically encountered in such forest habitat of this region include gray squirrel (Sciurus 5 0 F n ' carolinensis), white-tailed deer (Odocoileus virginianus), Virginia opossum (Didelphis virginia), Eastern chipmunk (Tamias striatus), Raccoon (Procyon lotor), Groundhog (Marmota monax), Striped skunk (Mephitis mephitis), Eastern cottontail (Sylvilagus floridanus), Eastern box turtle (Terrapene carolina), Northern copperhead (Agkistrodon contotrix), Northern black snake ' (Coluber constrictor), American crow (Corvus brabchyrhynchos), Northern cardinal (Cardinalis cardinalis), Carolina wren (Thryothorus ludovicianus), Pileated woodpecker (Dryocopus ' pileatus), and the blue jay (Cyanocilta cristata). ' Of the numerous threatened and endangered wildlife species listed by the U.S Fish & Wildlife Service (FWS) and the North Carolina Department of Environment and Natural ' Resources (NCDENR) that occur in North Carolina, no Federally listed threatened or endangered species have been reported on the project site. However, FWS records indicate that there are ' records of bog turtles (Clemmys muhlenbergii) within approximately 4.0 miles southeast of the project site. The bog turtle is not listed but is placed under "threatened due to similar ' appearance" status (see correspondence, Appendix Q. n u 0 Fj n I I u u I L 1 3.0 CULTURAL RESOURCES ' A search of the National Register Listings of Historic Places in North Carolina database revealed no historic sites within the project vicinity. CIS n ,7 I u 0 n f n n u I I n 0 0 E I I 4.0 DEVELOPMENT OVERVIEW The development plan for this Winston-Salem site includes the construction of approximately 300,000 square feet of commercial retail space, associated access roads, and a required stormwater management facility. The planning for this site sought to avoid and minimize impacts to wetlands and other waters of the United States, as well as other sensitive and/or valuable natural resources located on, or in the vicinity of, the project site. Site constraints, however, limit potential development configurations. These constraints include the presence of jurisdictional wetlands and other waters of the United States, project boundaries, topography, and stormwater management requirements. Taking the project requirements and ' environmental constraints into consideration, a land plan was prepared which attempted to minimize environmental impacts to the greatest extent possible. The site is severely constrained r [J 11 u iL ?7 by existing topography and resource areas within the northern portion of the project. In examining practicable development scenarios, the applicant evaluated the potential for avoidance of these resource areas within the context of the project goals and objectives. The option of reducing commercial area was also investigated. This option, however, was ultimately eliminated from consideration due to economic reasons. Further decreasing the amount of proposed building square footage on the project site is not possible due to the applicant's need to make an acceptable return on investment. 4.1 DEVELOPMENT ALTERNATIVES Two primary development alternatives were evaluated using the most efficient preliminary layout possible given the property size, the market demands along the Hanes Mall Boulevard corridor, the wetlands and other waters on the site and the location of the proposed stormwater management facility (BMP). In Alternative #l, aquatic resources were partially avoided (Map Pocket B). While this represents a reduction in direct impacts, we recognized that construction activity in this area would result in fragmentation, hydrologic alteration and possibly the erosion or siltation of the remaining wetlands and other waters of the U.S. Ultimately, the secondary impacts would result in the loss of wetland functions in this area and a permit modification would be required to address these impacts. In Alternative #2 (the Selected Alternative, Map Pocket C), the plan incorporates the wetlands and waters that would have a 8 F 0 E E I E 0 I n [I 11 n 11 n n u L high probability of being inadvertently impacted during construction even under the avoidance scenario developed in Alternative #1. 4. 1.1 Development Alternative #I The Development Alternative #1 in Map Pocket B depicts a conceptual buildout of the property with the goal of avoiding and minimizing direct impacts to wetlands and other waters of the United States. Where possible, building footprints were located outside of jurisdictional areas and impacts to jurisdictional resources adjacent to Hanes Mall Boulevard were avoided. In addition, the majority of the drainageway and floodplain for Area 11 was placed in open space, thus preserving the natural vegetation and wildlife habitat in these areas. The plan sought to preserve existing stream channel and incorporate a 30-foot buffer adjoining this stream segment. In addition, wetland impacts associated with the stormwater management pond in Area I were minimized. Total impacts resulting from this plan include approximately 160 linear feet of stream channel, 0.18 acres of wetlands and 0.06 acres of other waters of the U.S. This plan eliminates virtually all commercial development potential fronting Hanes Mall Boulevard. The steep topography adjoining the stream combined with limited upland area adjoining Hanes Mall Boulevard precludes development within this section of the project under the avoidance scenario. Concurrent with plan development, an evaluation of alternative stormwater management facility designs was conducted by Freeland & Kauffinan, Inc. to arrive at a feasible plan that meets the requirements of the City of Winston Salem, Forsyth County and NCDENR. Upon further evaluation, it was determined that the size of the conceptual storm water management facility proposed in this plan was not adequate. Additional impacts would be required in order to meet water quality standards and peak flow attenuation. The development layout must include the commercial development along the Hanes Mall Boulevard corridor. Limiting development along this corridor in a manner inconsistent with existing adjacent developed areas not only limits total return but also has a negative influence on the remaining commercial area proposed for this site. A great deal of effort was put forth to reduce impacts associated with site development and specifically within the Area II stream 9 I I E 1? n u I? 0 0 u segment. With the exception of one road crossing in this area, maximum avoidance was evaluated but determined to be an impracticable alternative considering the economic impact such a reduction in commercial space would have on the overall return on this project. In addition, WEG considered the probable secondary impacts to jurisdictional resources that might occur even under strict erosion and sediment control. Given the topography of the site, we anticipate continued degradation of jurisdictional resources beyond that which has occurred from adjoining development activities. As such, this alternative was dropped from further consideration. 1 H 11? 4.1.2 Development Alternative #2 (Selected Alternative) Development Alternative #2 (Map Pocket C) represents the selected alternative, which is the most realistic development scenario for the Winston-Salem site. The proposed impacts are unavoidable due to the limited space available to meet the project's purpose. This plan incorporates the wetlands and waters that would have a high probability of being inadvertently impacted during construction even under the avoidance scenario developed in Alternative # 1. This plan includes the implementation of a stormwater management facility that will enhance post-development water quality before waters leave the site. In addition, up-front recognition of the effects of development on wetlands and other waters in this area will allow for compensation for all impacts at one time, rather than incorporating secondary impact areas into a permit modification several years after the commencement of construction. Total impacts resulting from this plan include approximately 867 linear feet of stream channel, 0.32 acres of wetlands and 0.07 acres of other waters of the U.S. The following sections describe this alternative in greater detail. 4.1.3 Roads u I This development involves the construction of a main access road to the interior of the development, a secondary access point off of Hanes Mall Boulevard, and lateral connections to adjoining parcels along Hanes Mall Boulevard. The proposed 35-acre development involves the construction of one main. access at the existing intersection of Westgate Center Boulevard and Hanes Mall Boulevard. This access point will utilize existing traffic control on Hanes Mall 10 7 J J Boulevard and serve as the primary point for ingress and egress from the project. Secondary access will be provided approximately 560 feet west along Hanes Mall Boulevard. This secondary access will not include a median break on Hanes Mall Boulevard or traffic control. Each of these intersections provides a critical link for the flow of traffic through the development and incorporate traffic safety considerations. Ancillary access is proposed to adjoining parcels via connector roads extending east and west of the project site. Within the Winston-Salem development, 160 linear feet of waters (Area 11) and 435 square feet of other waters of the United States associated with Area I will be unavoidably impacted by roadway crossings. The City of Winston Salem is requiring access through the development to the rear of the commerce center along the Westgate Center corridor. This is designed to provide access to the adjoining parcel and will serve as the primary access point for property that is not owned by the applicant. This dictates the alignment of the roadway and has required additional modifications to the development plan that further reduced the commercial area available along the rear of the property. 4.1.4 Commercial Development I I n u u The development layout must include the commercial development along the Hanes Mall Boulevard corridor. A great deal of effort has been put forth to reduce the impacts associated with the commercial development and specifically within the stream segment in Area 11. Avoidance was evaluated but determined to be an unacceptable alternative considering the economic impact such a reduction in commercial space would have on both the overall return on this project as well at the tax base to the city. Within the Winston-Salem development, 707 linear feet of waters (Area H) and 0.32 acres of waters of the United States associated with Area I will be unavoidably impacted by the commercial area. One of several contributing factors influencing the commercial development potential along the Hanes Mall Boulevard corridor is the presence of the Duke Power Easement that essentially bisects the project from east to west. While this might appear insignificant, this limitation has a significant impact on the commercial layout. The need to develop a regional complex and the resulting traffic patterns dictate that large block areas be utilized. The applicant attempted to configure proposed development within various portions of the project site in an 11 J n u 0 u ' effort to minimize overall impacts to jurisdictional resources. Such alignments resulted in fragmented development plans that did not achieve project goals or traffic safety requirements. Alternative configurations were considered. The goal was to minimize impacts to ' jurisdictional resources while accommodating approximately 300,000 square feet of commercial space. The conceptual alternatives directly impact 160 linear feet of stream channel (Area II), ' 0.18 acres of wetlands and 0.06 acres of other waters of the U.S the United States. While this represents a reduction in direct impacts when compared with the selected alternative, we t recognized that construction activity in this area would result in fragmentation, hydrologic alteration and possibly the erosion or siltation of the remaining resources. Ultimately, the ' secondary impacts would result in the loss of aquatic resource functions in this area and a permit modification would be required to address these impacts. As such, we felt it prudent to simply ' account for the impact and mitigate accordingly. ' 4.1.5 Stormwater Management ' The evaluation of alternative stormwater management facility design was conducted by ' Freeland & Kauffman, Inc. to arrive at a feasible plan that meets the requirements of the City of Winston Salem, Forsyth County and NCDENR (Appendix D). The City of Winston Salem requires that all new developments provide for stormwater to be retained/detained on-site and ' released at the pre-development rate. The City requires that the pond be designed to hold and release the 10-year storm event. The county requires that the site be designed to retain erosion and sediment. The ' requirements are based on the state standards for Best Management Practices (BMP's) and require that the site be designed to have a minimum of 85% sediment removal. This can be t accomplished by the use of silt fence, inlet protection, sediment traps, and sediment basins. The proposed BMP is designed to handle the silt from the site by using a forebay to act as a settling ' basin before water flows into the main pond. ' The state will require water quality treatment prior to discharge into the existing culvert under Hanes Mall Boulevard. The water quality treatment is accomplished by using a wet pond 12 u n u F n ' that allows for evaporation of constituents and also allows for settling of suspended solids. The total development input to the proposed pond will be approximately 35 acres. The total area to the pond includes 8.0 acres of offsite runoff to the south of the site. This area cannot be diverted around the facility so it will be diverted to the pond. Existing inputs from the Lowe's Home ' Center will be directed around the site. ' The Stormwater Management Plan for the Winston-Salem site calls the construction of a BMP structure with a 40,538 square foot surface area incorporating approximately 9,000 square feet of vegetated wetlands. Impacts to jurisdictional resources associated with the structure include approximately 0.02 acres of forested-headwater wetlands and 0.04 acres of intermittent ' stream channel. These impacts are necessary to attenuate peak flows and to provide treatment for water quality before discharging into existing culverts. Additional impacts to the environment will be minimized through the implementation of ' strict erosion and sedimentation control plan to include immediate soil and slope stabilization, temporary sediment basins, silt fencing, and diversion dikes. u n 1 I I 13 n _7 1 n u 5 5.0 r J L F u L NMIGATION PLAN The primary objective of mitigation for unavoidable impacts to jurisdictional wetlands and other waters of the U.S. is to offset environmental losses, and in particular functional values lost. WEG personnel met onsite with North Carolina Department of Environment and Natural Resources (NCDENR) staff on February 12, 1999 for the purpose of stream evaluation. We walked the two main drainages and evaluated the biological significance of each as it relates to the need for compensatory mitigation. The NCDENR staff sampled for signs of aquatic life along the downstream segment of Area I using a "D-frame" kick net. The stream segment associate with Area I is a small drainage feature heavily incised in areas (Photo 1). life forms indicative of a perennial system were found. NCDENR staff concluded that Area I stream segments would not require linear foot mitigation. Area R was sampled from the downstream 54-inch culvert under Hanes Mall Boulevard to the upstream 48-inch culvert at the toe of fill associated with the Lowe's Home Center parking lot. No fish were found, however, crayfish were located along this stretch from the downstream culvert. up to the Duke ENR staff Power transmission lines cross the stre (Approximately 867 imdim concluded that this stream section would requ' clujumvpensato epacts exceed 150 linear feet. WEG personn el met onsite with the U.S. Army Corps of Engineers (Corps) on March 4, 1999 to determine the biological significance of the streams under the Corps' purview. A 36- inch culvert under Hanes Mall Boulevard in the northeast corner of the property appears to have increased inflows into the project site. This has resulted in the erosion of 0.02 acres of wetlands previously associated with the Area 11 drainage (Photo 6). During this site inspection, the Corps ruled this drainage, from its origin under Hanes Mall Boulevard to the confluence with the main stem, as non jurisdictional. Otherwise, the Corps supported NCDENR findings that the main stem of the Area H stream is jurisdictional and impacts greater than 150 linear feet would need to mitigated on a linear foot basis. The Corps review of Area I stream segments indicated these areas were jurisdictional, however, due to their small size they would be mitigated on a square foot basis. In an effort to adequately mitigate for the unavoidable impacts to 867 linear feet of stream channel (Area 11), 0.32 acres of nontidal forested-headwater wetlands and 0.07 acres of 14 1 J n H J I H ' other waters of the U.S. (Area I), the applicant investigated various compensation options including onsite creation, offsite creation, and offsite preservation of significant or sensitive ' aquatic/wetland environments. The 0.07 acres of waters impacted in Area I should be adequately compensated thought the creation 40,538 s.f. of ponded surface area within the proposed BMP. ' Onsite creation of wetlands, however, is not feasible due to the limited project size and severe topography. A wetland creation ratio of 2:1 would require the excavation and planting of ' approximately 0.64 acres of forested wetlands and the creation of 867 linear feet of stream channel. This project site will not support any kind of commercial development and such a ' mitigation compensation site. A review of adjacent properties revealed that most uplands are either developed or are in the process of developing. In addition, no disturbed offsite areas were ' determined to be suitable for wetland restoration or creation. As such, the applicant proposes to make a contribution to the Wetlands Restoration Program (WRP) in the amount of $123,735.00 (867 l.f. x $125.00 + 0.64 acres x $24,000), subject to Corps and NCDENR approval. n n L r E 15 71 u n u I I 6.0 REGULATORY SUMMARY ' Isakson-Barnhart, the applicant, is proposing to construct a commercial retail center within a 35-acre tract of land in the City of Winston Salem, North Carolina. The development ' plan for this Winston-Salem site includes the construction of approximately 300,000 square feet of commercial retail space, associated access roads, and a required stormwater management ' facility. The planning for this site sought to avoid and minimize impacts to wetlands and other waters of the United States, as well as other sensitive and/or valuable natural resources located ' on, or in the vicinity of, the project site. Site constraints, however, limit potential development configurations. Two primary development alternatives were evaluated using the most efficient ' preliminary layout possible given the property size, the market demands along the Hanes Mall Boulevard corridor, the wetlands and other waters on the site and the location of the proposed ' stormwater management facility (BMP). In Alternative #1, aquatic resources were partially avoided (Map Pocket B). While this represents a reduction in direct impacts, we recognized that construction activity in this area would result in fragmentation, hydrologic alteration and possibly the erosion or siltation of the remaining wetlands and other waters of the U.S. ' Ultimately, the secondary impacts would result in the loss of wetland functions in this area and a permit modification would be required to address these impacts. In Alternative #2 (Selected ' Alternative, Map Pocket C), the plan incorporates the wetlands and waters that would have a high probability of being inadvertently impacted during construction even under the avoidance ' scenario developed in Alternative # 1. ' A great deal of effort was expended by the project team analyzing the development plan to reduce direct impacts and account for all secondary impacts resulting from the project. Total permanent impacts to jurisdictional waters are expected to be approximately 0.39 acres of forested-headwater wetlands and intermittent stream channel and 867 linear feet of other waters of the United States. The total impacts to jurisdictional areas proposed by the development plan ' are itemized in Table 6-1.

In summary, the applicant has attempted to avoid and minimize impacts to jurisdictional wetlands and other waters of the U.S. to the greatest extent practicable within the project site and its vicinity. The site is severely constrained by existing topography and resource areas within the northern portion of the project. In addition, existing development within adjoining parcels continues to degrade on-site resources and would be expected to continue even in the absence of the proposed development. This was made apparent with the erosion of 0.02 acres of wetlands within Area H since the site was confirmed in 1995 and the appearance of degraded stream ' conditions including eroding banks with exposed root material and evidence of increasing sediment deposition. In examining practicable development scenarios, the applicant evaluated the potential for avoidance of these resource areas within the context of the project goals and objectives. The option of reducing commercial area was also investigated. This option, ' however, was ultimately eliminated from consideration due to economic reasons. Further decreasing the amount of proposed building square footage on the project site is not possible due to the applicant's need to make an acceptable return on investment. As such, the applicant will compensate for the permanent unavoidable impacts through a contribution to the Wetlands Restoration Program (WRP), subject to Corps and NCDENR approval.

STATE REASONS WHY IT IS BELIEVED THAT THIS ACTIVITY MUST BE CARRIED OUT IN WETLANDS. (INCLUDE ANY MEASURES TAKEN TO MINIMIZE WETLAND IMPACTS): Two primary development alternatives were evaluated using the most efficient preliminary layout possible given the property size, the market demands along the Hanes Mall Boulevard corridor, the wetlands and other waters on the site and the location of the proposed stormwater management facility (BMP). In Alternative #1, aquatic resources were partially avoided (Map Pocket B). While this represents a reduction in direct impacts, we recognized that construction activity in this area would result in fragmentation, hydrologic alteration and possibly the erosion or siltation of the remaining wetlands and other waters of the U.S. Ultimately, the secondary impacts would result in the loss of wetland functions in this area and a permit modification would be required to address these impacts. In Alternative #2 (Selected Alternative, Map Pocket C), the plan incorporates the wetlands and waters that would have a high probability of being inadvertently impacted during construction even under the avoidance scenario developed in Alternative #1. The site is severely constrained by existing topography and resource areas within the northern portion of the project. In examining practicable development scenarios, the applicant evaluated the potential for avoidance of these resource areas within the context of the project goals and objectives. The option of reducing commercial area was also investigated. This option, however, was ultimately eliminated from consideration due to economic reasons. Further decreasing the amount of proposed building square footage on the project site is not possible due to the applicant's need to make an acceptable return on investment. 15.

I checked our records, and we do not have. Any species occurrences in the immediate vicinity of the location of your project. We do have records of bog turtles from nearby (-3.9 nu southeast). I suggest you consider this species in yuu, analysis. 3. We are most concerned about potential impacts to the streams and wetlands. We suggest maintaining buffers of at least 30 feet along any streams within the project area, rninim ng disturbance to vegetation, and revegetate any disturbed areas within two weeks of construction. L J 7 1 n A successful stream mitigation plan will need to first describe what the natural channel design is relative to the principles of fluvial geomorphology. We will likely recomumend the following elements be included in any stream mitigation fhr this project: a. Riparian vegetation should inaludr, nntive woody species, such as alder (A)mts spp•), black willow, and dogwood, as well as Arundinaria, sedges, grasses, and rushes, as appropriate to the area, Exotic vegetation should be screened from any plant material. Large woody species will provide thermal cover as well as deep bank-stabilizing root systems along the constructed/reconstructed stream channel. b. Stream channel construction and vegetation establishment should take place prior to the diversion of water into the new channel.. Sequential construction of segments and temporary pipe diversinnr can be utilized to ensure channel stability. We would like to have an opportunity to inspect stream segments for stability prior to the water diversion. C. Stream channel design should mimic slope, riffle slope, pool slope, valley slope, meander geometry, sinuosity, cross-sectinnai dimensions, entrenchment ratio, bed material (pebble count), and bank-full discharge of a nearby reference reach of a stable stream ofthc same classification (Rusgvtt 1996). Sank-full dimensions should be generated based on those of an appropriate reference reach and/or the latest discharge/channel dimension relationship developed for the Piedmont (we u r u u n u I I vir vl ? oo 1I&V 1 r co raa I M4 LJO 40%ty rrro AI*nLV IJILXI can supply a copy of these curves if needed). We would like to review the final ' dcsign of the stream channel restoration and relocations. d. Monitoring should continue for at least 5 years following channel construction. ' Annual reports should be submitted to the resource ageneics. Resource ageuuics should be notified of problems with success or function of the stream mitigation witUi 30 days of detection. ' e. An appropriate regional conservation organization should hold title to the deed rPCtrielions on the mitigation site. The title to the conservation ea5cmcnt shoulJ be ' conveyed along with an endowment for future monitoring, management, and any wiitinbencies to ensure a perpetual net increase in stream channel function in the project area. ' f. Thn final mitigation plan should provide details relative to what measures will be taken to control watershed conditions and prevent sediment pollution and ' increased water discharge that would potentially negate efforts at the stream mitigation site(s). ' 3. The lxtexr draft "Guidelines for stream relocation and restoration in North Carolina," by the North Carolina Wildlife Resources Commission, is a good guide to proper stream restoration and relocation wunk. We do recommend obtaining a copy of the "Base nwide Wetlands and Riparian, ' Restoration Plan For The YadIdn-P= Dec River Basin" as a source of information about potential sites. This document was published in September by the North Carolina Wetlands Restoration program of the Division of Water Quality.

GREENVILLE, SOUTH CAROLINA 29609 F n 1 I I n Winston Salem Drainage Study Isakson - Barnhart Development Hanes Mall Blvd. next to Lowes Forsyth County, N.C. DRAINAGE STUDY AND WATER QUALITY REPORT The following is the drainage study for the proposed Costco Shopping Center to be built along Hanes Mall Blvd. across from the existing Home Depot and south of the existing Lowes Store. The site is being proposed to be developed to contain a +/- 145,946 s.f. Costco Store, a +/- 75,000 s.f. "mini-anchor", a 30,000 s.f. Babies R Us, various shops space totaling 28,380 s.f., a 24,000 s.f. Staples, and assorted other outparcels and commercial space. The layout may contain the addition of a new road (an extension of Westgate Center Blvd.) but this has not been determined at the time of this report. There is also off-site runoff that will drain on to the site although a large portion of the off-site runoff from the Lowes site and Hanes Mall Blvd. will be routed around the site. The report includes determination of required pond size for water quality as well as quantity. The State of North Carolina Dept. of Environment and Natural Resources requires the treatment of water any time the disruption of a wetlands or stream occurs over 1501.f. The City of Winston Salem requires that water quantity storage be accomplished to store and release the runoff at the pre-developed rate not to exceed the 10 year design storm. Lastly, since the runoff empties to a state road system, the pond will be analyzed for the 25 year storm event and measures shall be taken to store this runoff as well. In the final design phase of the project, once final plans are established, the city and state will require that sedimentation and erosion control will also be handled in this project to protect downstream areas from silt. Plans also include the accompanying parking and landscape areas. The existing stormwater system along Hanes Mall Blvd. will be utilized to take the runoff from the pond as this is where the current runoff pattern lies. All runoff from the developed site will be directed to a proposed pond located in the western front corner of the site. We will also be researching alternative methods for stormwater storage to try and accomplish the pond in an underground system. There are no underground storage system currently approved by the NCDENR but they do have a procedure where, if a system is proposed and can be proven to meet the requirements of the state they will be willing to review it. The new pond will be sized to handle the first 1" of runoff and release it over a 48 hour period, the 2 year and 10 year storm events and restrict these storm events to the pre-developed rates. The pond will have a staged outlet to manage each storm. The 100 year storm event will overtop the outlet structure but will not overtop the pond. The stormwater runoff calculations shown in this report are based on the SCS TR-55 Method as required by the State of North Carolina and the City of Winston Salem. The runoff numbers and hydrographs are included. I I I f :? I 1 1 \\\ \ I 1 I IKin? CE POWER ?'1\11;111;11 1 1 \ \\ \ 1 1 I \ /iiii ,/ /'i ??

The fast is on the eastern side and leads from south to north towards Hanes Mall Blvd. The runoff drains through wooded areas and eventually into an existing channel that flows north to Hanes Mall Blvd. From there the runoff enters a 54" pipe and is conveyed down the road to an existing creek. This drainage area also picks up the runoff from the Lowes Store on the east side and a portion of Hanes Mall Blvd. The runoff from Lowes and the road will not be affected by the new development as it will be piped around the system. The second drainage area encompasses the "middle" of the "site and takes in most of the proposed development area. There is also an area of off-site drainage to the south of the site that flows through this section and will continue to flow through in the developed state. Again, the flow sheets through wooded areas into an existing channel and ultimately to a 42" culvert at Hanes Mall Blvd. The last drainage area is a small section in the southwest corner that drains south and west off the property into a completely separate drainage basin. This area will not be affected by the development. The total the site is +/- 40.0 acres with areas of off-site drainage coming onto the property. Slopes on the property vary but in general the site slopes from south to north. The bulk of the slopes are 10% and get somewhat flatter in areas in and around the creek. Soil types consist of type "B" soils as defined in the TR 55 manual and the Handbook on Erosion Control design as issued by the state. These soils are mostly clays and sands with small elements of loam and loamy sands. These soils are well drained, are moderately permeable and have a medium capacity for water. Surface runoff is generally rapid to very rapid. The closest body of water to the site is "Little Creek" located north and west of the property that leads west. The most northern extreme end, towards the west side, may lie within a Flood Zone. Wetlands described as waters of the United States (creeks) are present on the site. Refer to map provided by Williamsburg Environmental Group for more detail. I I ' Developed Conditions: ' In the developed condition the site will be used for commercial development. This will consist of several "big box" users that may include Costco, Staples, etc. There will also be smaller shops spaces available that may total 30,000 s.f. The development will include a field of parking, stormdrain system, and all accompanying utilities. The developed condition will also include the installation of a stormwater pond to control both quantity ' and quality of runoff that leaves the site. The pond will be sized to meet both the State of e i N th C li t d th Cit f Wi t l S R i na r qu remen or aro e y o s an ns on a em equ rements. ' Permitting and Regulatory Requirements: The permitting for stormwater falls into several categories, each divided by jurisdictional ' body, but all applying. The plans must be reviewed by the City of Winston Salem, the County (in this case Forsyth County) for sediment and erosion control, and finally the state (NCDENR) for water quality. We will discuss each body and what each will be ' reviewing and then discuss how all will need to be met. The City of Winston Salem requires that all new developments provide for stormwater to ' be retained / detained on site and released at the pre-developed rate. This is standard practice for most towns and requires that the runoff be held in a "pond" and then released through an outlet structure to an existing culvert system or natural drainage way. The City ' requires that the pond be designed to hold and release the 10 year storm event. The 10 year storm is not a storm that can only happen once every 10 years as the name would imply but rather a storm that has a 10 percent chance of happening each year. The storage ' can be accomplished with a surface pond (as shown on these plans), by storing water in underground vaults or pipes, storing the water on the parking surface, or a combination of these methods. The outlet structure is designed to release the runoff in stages by releasing ' the 2 year storm first, then releasing the 10 year storm etc. However, since the outlet will empty to a state road we have designed the system to hold and release the 25 year storm. ' The county requires that the site be designed to retain sediment and erosion. The requirements are based on the state standards for "Best Management Practices" and ' require that the site be designed to have a minimum of 85% removal of sediment. This can be accomplished by the use of silt fence, inlet protection, sediment traps, sediment basins, etc. We have designed the pond to handle the silt from the site by using a ' "forebay" in the pond that acts as a settling basin. The surface area is also based on the depth of the pond and the overall developed area draining to the pond to provide for the 85% removal. Lastly, the state will also have jurisdiction on the project because of the proposed disturbance of wetlands. Due to this disturbance we are required to provide water quality ' treatment prior to turning the stormwater loose to the Hanes Mall Blvd. system. The water quality is accomplished by the use of a wet pond that allows for evaporation of phosphates, nitrogen, etc. and also allows for settling of suspended solids. This requires that we store the first 1" of runoff and release it over a 2 to 4 day period. ' The total developed condition to the new pond will be approximately 3 8 acres of pavement, roof and grass. The total area to the new pond also includes 8.0 acres of off- s to the south of the site. This runoff can not be piped around the development so it will be diverted to the pond. As stated earlier the off-site runoff from the Lowes store and from Hanes Mall Blvd. will be directed around the site via new piping. All disturbed ' areas not receiving pavement will be grassed with a permanent grass mixture upon completion of grading. These numbers will be used to obtain the Runoff Coefficient that is a definition of percent impervious area. ' The slopes of the new parking lot will range from I% to 4.0 % with driveways ranging up to 10% and all will drain to a series of catch basins which will lead via underground pipes ' to the new retention pond. The outlets into the pond will be submerged due to the pond having a permanent pool.

Runoff Curve Number : The developed condition will consist of parking areas and the roof areas of the shopping center. This water will sheet across the parking lot to catch basins and be conveyed via pipes and ditches to the pond. The pond will also be sized to accommodate the additional pavement area.

The required quantity is based on the 1" of runoff being stored and released over a 48 hour period, and storing and releasing the 2 year and 25 year storms at their pre-developed rates. The quality storage will be provided by supplying a defined storage area (in square feet) as determined by the depth of the permanent pool and the surface area to drainage area ratio. Our fast proposal is to provide the pond area and volume in a "surface" pond. The pond, as can be seen on the grading plan, will be a surface pond with a bottom elevation of 766.0, a permanent pool elevation off 772.0, and a top elevation of 780.0. Based on the depth proposed of 6 feet, the required surface area for the 38.2 acre drainage area is 32,781 s.f. The surface area provided at elevation 772.0 is 40,538 s.f. This surface area must be provided regardless of how the quantity is provided unless a new and "innovative" system is proposed. The state allows for innovative systems as long as the system can be proven to meet the state requirements and the state is given a chance to review and approve the new system. Based on these requirements we have sized the outlet to release the runoff at the various stages. The resulting outlet will have to release runoff to the two existing culverts on Hanes Mall Blvd. For this reason there will actually be two outlets for the pond, each sized for the individual pre-developed areas. To release point `A' the outlet will have a 2.72" orifice. This will be accomplished with the use of a 2 %2" pvc pipe at elevation 772.0 that will elbow down into the permanent pool. The 2 year storm will be released through an orifice. The orifice will be 7.2" in diameter. The 25 year storm will be release via a weir at the top of the 2 year storage elevation. This weir will be 1.0' in length at elevation 776.3. The 100 year storm will overtop the riser and exit through the outlet pipe. For the release to Point "B' the outlet will have the same 2 %2" pvc pipe. The 2 year release will be through an orifice placed at the top of the 1" storage (el. 774.33). The orifice will be 14.6" in diameter. The 25 year storm will be released through a weir at the top of the 2 year storage elevation. The weir will be 1.89 feet in length. Again, the 100 year storm will overtop the riser and exit through the outlet pipe. Refer to the calculations included for more details of required volumes The outlet pipes from each riser are sized as follows; Manning's Equation - Q= 1.49/n x A x R^2/3 X S^1/2 ' From this equation it is determined that the required pipe size for each outlet will be 42". Refer to the hydrographs for reservoir routing showing storage elevations, release rates, etc.. The results are as follows: POND Stage Storage Voluhie Allowable Release Actual Release First 1" 774.33 101,930 0.6 cfs 0.6 cfs 2 . 776.20 193,996 cf 10.67 cfs 10.17 cfs 25 . 779.0 352,802 cf 57.68 cfs 56.89 cfs 100 yr. 779.70 392,584 cf N/a 112.32 cfs ' As can be seen in the above table the release rate from the pond for the 2 yr. and 25 yr. storm events is below the allowable release rates in the pre-developed condition.
