This letter is in response to your comments on the project. The permit application had been marked the incomplete due to avoidance and minimization. Comments are addressed in the same order in which they were asked. A. In accordance with 2017 Nationwide Permit General Condition 23(a), the activity must be designed and constructed to avoid and minimize adverse effects, both temporary and permanent, to waters of the United States to the maximum extent practicable at the project site (i.e., on site). The term practicable means available and capable of being done after taking into consideration cost, existing technology, and logistics in light of overall project purposes (see 40 CFR 230.3(1)). The Corps understands that the Huntersville area and general Charlotte metro market enjoys a substantial demand for speculative warehouse space. However, we are concerned that the applicant has not avoided and minimized impacts to waters of the United States to the maximum extent practicable as required by regulation. We have compared this proposal with eight similar speculative warehouse/distribution facilities that have received Section 404 discharge permits in the general Charlotte area over the past year. The summary of these findings are detailed on the attached spreadsheet. We looked at the square footage proposed per acre because property size is often a primary siting criteria used for such developments. The applicant is proposing building square footages per acre that are 23% higher than the highest reviewed and 42% higher than the average per acre across all sites reviewed. This would seem to suggest that reducing the size of or completely eliminating building 200 would be practicable since it has been achieved by many other developers in the market. We believe this may eliminate the need for a waiver altogether. Please explain in NORTH CAROLINA • SOUTH CAROLINA WWW.CWS-INC.NET Patterson Rd May 16, 2019 Revised: May 20, 2019 Response to Request for Additional Information CWS Project No. 2018-0215; SAW -2018-02209 detail why it is not practicable for the applicant to reduce the size of or eliminate building 200. RESPONSE: The applicant has made substantial effort to avoid and minimize impacts to Waters of the US to the maximum extent practicable. As noted in the authorization request, the applicant conducted preliminary analysis of off-site properties for the project that were determined to not be feasible for the proposed development. The applicant then conducted a wetlands delineation of the project area during the pre -planning stage for siting of the project infrastructure. The applicant also carefully evaluated both economics and functional issues in the determination of the suitability of the site for the proposed development type and prepared their project plan within the confines of the functional needs for that particular warehouse spacing plan. These factors were weighed together to ensure the financial feasibility and successful operation of the project. Significant changes to these model types will make the project impracticable. The applicant was able to make several plan changes that avoid impacts to the majority of the features on the project area. However, the location of Streams A and B (S1 and S2), which bisect the eastern portion of the project, does not allow for the site to be used to its full capability for the planned development type without some portion of the features being impacted. Efforts to avoid and minimize impacts to the stream on the eastern portion of the site In a pre -application meeting with USACE and other agencies on March 14, 2019, the applicant discussed seeking an Individual Permit (IP) for impacts of 794 If of streams. As a result of the comments from USACE and EPA, the applicant revised the plan and submitted the NWP application seeking a total of 616 If of permanent stream impacts with an IP waiver. Through these revisions, the applicant was able to avoid all impacts to the streams on the west parcels (S3 and S4). Following submission of the project for Nationwide Permit 39 authorization, USACE (David Shaeffer) emailed comments on April 25, 2019 whereby he requested further avoidance and minimization. The applicant reviewed the model for this type of warehouse use in the context of site configuration and determined that a shift in the location of car parking at Building 200 and incorporation of a retaining wall at the east end of the parking lot could be made that would further reduce the total permanent impacts for the project to streams S1 and S2 to 498 If (Attached Revised Construction Sheet). Any further reduction to impacts would make the project impracticable for its planned use. Reasons why it is not practicable to reduce the size of Building 200 In the April 25, 2019 emailed comments regarding avoidance and minimization, the USACE asked: Please explain in detail why it is not practicable for the applicant to reduce the size of or eliminate building 200. The project has been designed specifically for rear -load buildings with a shared truck court, which are ideal for a project site of this size and shape. Page 2 of 5 Patterson Rd May 16, 2019 Revised: May 20, 2019 Response to Request for Additional Information CWS Project No. 2018-0215; SAW -2018-02209 • The rear -load buildings that the applicant proposes to develop on Patterson Road are designed for users that need depths between 180-260 feet; building depths outside of this range would not be marketable. • The applicant has designed this project with shared truck courts between pairs of rear -load buildings, and the buildings with the truck court between them fit well on the site. • The proposed buildings will be used by companies needing significant employee parking, and thus further reduction to the overall car parking count will make the project impracticable for the planned use. • Stream S1 cuts the site from the northern property line toward the center of the site. Any further avoidance of the stream results in substantial loss of building area and car parking, which the economics of the project cannot withstand. Property Size vs. Property Shape The density (average building area per acre) of a warehouse development project is more a function of the shape of the property, than its size. In addition to comparing warehouse projects on their density like in the spreadsheet presented (dated April 25, 2019), the property shape should be accounted for in the comparison. The spreadsheet presented by USACE on April 25, 2019 is slightly misleading, as it is comparing warehouse projects solely on their density, and does not account for property shape in their planning. There are numerous physical characteristics of warehouse development that limit the placement of buildings on sites in a cookie -cutter fashion, and that ultimately dictate the overall density of the project. These characteristics include: Office - warehouses buildings are more rectangular than square, and sites must be able to accommodate these rectangular configurations. Different product types have building depths that are optimal for certain users. For example, bulk distribution, cross -dock facilities can be as deep as 500-600 feet, whereas rear load office/warehouse buildings need to be 180-260 feet deep in order to function for smaller users. Some building types require single -loading design with a dedicated truck court on one side, while others are most marketable and financially realistic with a shared truck court between a pair of buildings. The applicant analyzed the spreadsheet provided by the USACE on April 25, 2019 and identified a few errors in building sizes that were presented. Based on the applicants internal market analysis data, those errors were corrected. Table 1 shows corrected figures for several of the projects contained in the spreadsheet, as well as the nearest competitive project in Huntersville that did not require a USACE permit. Page 3 of 5 Patterson Rd May 16, 2019 Revised: May 20, 2019 Response to Request for Additional Information CWS Project No. 2018-0215; SAW -2018-02209 Table 1. Corrected market analvsis spreadsheet for warehouse proiects by size Project Name Project Area Building Area (SF) SF / AC L&C-A Silverpark North/Huck Road 26 305,760 11,760 John Price Road 46.74 621,000 13,286 Airport South 54 583,987 10,815 Bryton Comm Ctr (no permit) 47.42 659,937 13,917 The property shapes of the first three projects above are very irregular, with portions of the site that will not accommodate any building area. It is this irregularity in the shapes of the sites that contribute to less efficiency and lower building SF per acre. By contrast, the Bryton Corp Center project is being developed on a very efficient site that is rectangular. As a result, the density of that project is within 5% of the density of the Patterson Road project site, which also is an efficiently -shaped site: largely rectangular parcels on both sides of the road. The site size, site configuration, project plan type and amount and location of wetlands and streams on each project area likely vary, which may also play a role in the amount of impacts that a site may have. This amount of variation presents some error in using only total building size and acres in comparing warehouse projects. For example, the 7800 Tuckaseegee Road project is smaller in size, has less linear footage of stream, and a smaller building footprint, yet the impacts to streams are 4% greater than those on the proposed Patterson Road Project site. Therefore, the applicant reasserts that they have worked to the best of their ability to avoid and minimize impacts from their proposed project in order for their project to be economically reasonable as planned. B. I have determined that parts of this project do not qualify for a Nationwide Permit 39 because the project would result in discharges (S3 and S4) of fill material into perennial streams and/or intermittent streams for stormwater management facilities (see Regional General Condition 4.1.1). Please revise the plans and/or PCN accordingly and resubmit as necessary. RESPONSE: This comment has been retracted by USACE. Email received from David Shaeffer, dated April 26, 2019.

Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: The project area consists of maintained fields and undeveloped forested areas. Land cover within the project area consists of deciduous forest, mixed forest, developed open fields, woody wetlands and emergent herbaceous wetlands. Forested areas appear to be primarily early to mid -succession in age and development, and visual observations indicate recent and historic land clearing and timbering activities within forested areas. 3b. List the total estimated acreage of all existing wetlands on the property: 0.054 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: 994 (intermittent) total 3d. Explain the purpose of the proposed project: McDonald Development has been researching the Charlotte market for a long time to identify a suitable site to develop for a business park. A meeting in early 2018 with Lake Norman ED reps indicated they receive a steady flow of requests from existing Huntersville companies and users new to the market for manufacturing, R&D and office/distribution space in and around The Park — Huntersville. In the past year, the demand for industrial space in Huntersville was more than 2,300,000 SF. The users ranged from 10k SF up to 400k SF, with most between 20k — 100k SF, and they were looking for quality facilities. A lot of this demand is a result of the connectivity in Huntersville now that I-485 has been completed in both directions to I-85. The project purpose is to develop the project site as an industrial park to serve the unmet demand for first-class warehouse and manufacturing space in the Huntersville submarket. 3e. Describe the overall project in detail, including the type of equipment to be used: McDonald Development is proposing a new industrial development along Patterson Road just north of the Hambright Road intersection in Huntersville, NC. The site is approximately ±61 acres in size and is currently vacant farmland and forest. The site is split by Patterson Road with approximately 30 -acres on the west side and 31 acres on the east side. The new development proposes to construct an industrial park with access points from Patterson Road. Currently, the Town of Huntersville is reconstructing Patterson Road to an industrial standard road section from Hambright Road to a point approximately 2,000' north near an existing Duke Energy transmission line. The Town is also planning to continue Patterson Road north to Vanstory Road in the future. The subject site is planned to be developed as an industrial park comprising of approximately 906,600 SF of building space. The project will also include other site improvements such as vehicular parking, truck court and loading areas, utilities including storm/sewer networks, landscaping, and lighting. In addition, an 1,800' public sanitary sewer line is also being proposed to serve the overall development. The proposed on-site sewer will make a connection to an existing off-site line along the eastern property boundary without impacts to jurisdictional waters. At final build -out, the industrial park will have an approximate 65-70% imperviousness. Fill slopes from the edge of the park to the property Page 3 of 15 Page 4 of 15 boundaries will be maintained at a 2.5:1 gradient, at its steepest. Stormwater runoff from the buildings and parking lots will be directed to the proposed onsite collection system and directed to on-site stormwater detention ponds for flow detention and water quality improvement. The Patterson Road project proposes unavoidable impacts to jurisdictional waters under Nationwide Permit (NWP) No. 39 with the construction of a new industrial park. Grading and fill placement for site development will result in temporary and permanent stream impacts, as well as, permanent wetland impacts. Proposed site development includes fill placement in two streams, A and B, resulting in 498 If of permanent stream impacts (S1 & S2). An additional 20 If of temporary fill stream impacts (S3) is proposed to prevent water quality pollution during fill placement in the upstream channel. Temporary fill will be placed on the lower end of the permanent stream impacts to create an impermeable dike for capturing stream flow and sediment that may be held in solution. Stream water will be pumped from the pooled area at the dike and directed to a filter bag located in the uplands where sediment will be collected. Clean stream water will be diverted from the filter bag back to the stream channel below the dike to maintain hydrology during construction. A retaining wall is proposed at the downstream terminus of impacts to Stream A to stabilize the stream and reduce the amount of grading needed for the parking lot, limiting impacts to Stream A. Proposed site development includes fill placement in one wetland, CC, resulting in 0.016 -acre of permanent wetland impacts (W1). The impacted wetland is forested and located in a natural crenulation, adjacent to a seasonal RPW (Stream A). The applicant requests a waiver of the 300 If limit on impacts to streams, as provided for in NWP 39, on the basis that the proposed impacts will result in minimal individual and cumulative adverse environmental effects. Stream A and B are both classified as intermittent and scored `Low' quality using NCSAM. Historic on-site land -use has included clearing of forested areas, agricultural, and ditching, which has resulted in moderate to severe channel incision within Stream A. Abandoned agricultural ditches were observed abutting and directed to Stream A, which are contributing stormwater flows and sediment inputs. Recent field observations found that Stream A is moderately to severely unstable and actively contributes sediment to downstream waters. Stream bed substrate is dominated by sand and silt, indicative of active erosion in the stream channel. Stream bank heights were observed between 6 and 15 feet, indicating active downcutting of the stream bed and active bank erosion. Several deep head cuts were observed in the channel, indicating the stream bed is unstable. Macrobenthic populations were evaluated during site assessments, and findings indicated low quality species in low abundance with poor diversity. The overall function of the affected resource is relatively low, as its biological and chemical functions are degraded, and the stream system contributes to water quality pollution (sediment) in the watershed; hydrology appears to be primarily stormwater driven. The relative importance of Streams A and B to the region is low, as their primary contribution is stormwater conveyance and support of riparian forested areas. Affected riparian forested areas have historically been impacted by timbering and agriculture with a high degree of invasive species competition. The environmental setting in the vicinity of the NWP activity is undeveloped -forested, residential, industrial, commercial development, and transportation. 4. Jurisdictional Determinations 4a.

Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. To avoid and minimize adverse effects to jurisdictional waters to the maximum extent practicable the Patterson Road site was delineated, and on-site aquatic features were verified by the USACE during a site visit on February 12, 2019. A Concept Plan was developed by Bohler Engineering in early February of 2019, just prior to the Corps visit. However, once the USACE verified on-site aquatic features, an alternative site plan (No.1) was developed using the Concept Plan to reduce impacts to on-site jurisdictional waters. Alternative Plan No.1 was presented to the USACE, USEPA, NCDEQ-DWR, and NCWRC for review as part of a permit pre -application meeting. The results of the pre -app meeting determined the scope of the project was too narrow for using an Individual Permit. The USEPA and USACE offered to consider waiving the Individual Permit threshold if stream impacts could be further reduced, allowing the project to be permitted under a Nationwide Permit. Alternative Plan No.2 was developed following the pre -app meeting, which significantly reduced the overall proposed impacts to jurisdictional waters of the U.S. Due to comments from the USACE, Alternative 3 was developed further reducing impacts to jurisdictional waters. Therefore, Alternative Plan No.3 is the preferred plan in pursuance of an NWP No.39 with an IP waiver for the Patterson Road project. No -build Option: A no -build option was considered, which includes consideration of off-site alternatives. The proposed park needs to connect to existing and planned roads to provide convenient access to 1-77 and 1-485, and utilize existing municipal water & sewer, and local electric and gas utilities. A total of 17 sites were identified during the initial market search, which was later narrowed down to three short list sites, including the Patterson Road site. The other two short list sites (Everette Keith Rd and 6855 Old Statesville Rd) were deemed unsuitable due to an irregular shaped property unsupportive for preferred building configuration/size and increased impacts to on-site jurisdictional waters of the U.S. The Patterson Rd site supports the proposed facility configuration and reduces the amount of impacts to jurisdictional waters. Therefore, the Patterson Road site is being purchased to meet the growth and demand for commercial warehouse space in the Huntersville area. However, a no -build option would not meet the project goals and is therefore eliminated from consideration. • Concept Plan: The Concept Plan was developed on February 11, 2019 and maximizes the entire project site boundary. The Concept Plan has a total of 960,460 sf or 22.05 ac of building footprint. Associated parking and truck courts are scaled to the building footprint; larger building footprint requires more parking and larger truck courts. This plan depicted two stormwater BMP detention basins located within three stream channels and fill placement for site development within four stream channels and three wetlands. The total permanent impacts to waters of the U.S. with the Concept Plan is estimated to be 994 If of stream and 0.054 ac of wetlands. Alternative Plan No.1: Alternative No. 1 was developed following the USACE site delineation verification, and this plan was presented to regulatory agencies during a permit pre -application meeting. Alternative Plan No. 1 reduced the building, parking, and truck court footprint, as well as, the stormwater BMP detention extent compared to the Concept Plan. Total building footprint size is 906,600 sf or 20.8 ac. This plan depicts two stormwater BMP detention basins located within three stream channels, but the basins were reduced in size due to an overall reduction in site imperviousness. Total impacts to waters of the U.S. with Alternative No.1 is 794 If of stream and 0.021 ac of wetlands. Alternative Plan No.2: Alternative No.2 was developed following the regulatory agency permit pre -application meeting in order to lower proposed impacts to waters of the U.S. to the maximum extent practicable in pursuance of an NWP No.39 with an IP waiver. Alternative No. 2 reconfigures parking areas, increases fill slopes to the maximum allowable gradient (2.5:1), and changes the shape and extent of the stormwater BMP basins to avoid stream impacts. This plan reduces proposed impacts to jurisdictional waters while maintaining the project purpose and need. Total impacts to waters of the U.S. with Alternative No.2 is 636 If stream (616 If permanent) and 0.042 ac of wetlands. Alternative Plan No.3, Preferred Alternative: Alternative No.3 was developed in response comments from David Shaeffer of the USACE in order to lower proposed impacts to waters of the U.S. to the maximum extent practicable in pursuance of an NWP No.39 with an IP waiver. Alternative No. 3 reconfigures parking areas, increases fill slopes to the maximum allowable gradient (2.5:1), and proposes a retaining wall at the downstream terminus of impacts to Stream A in order to reduce the amount of grading necessary for the on-site parking lot. This plan reduces proposed impacts to jurisdictional waters while maintaining the project purpose and need. Total impacts to waters of the U.S. with Alternative No.2 is 518 If stream (498 If permanent) and 0.016 ac of wetlands. b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Temporary fill placement below the area of permanent stream fill will be used to prevent water quality pollution during fill placement in the upstream channel. Temporary fill will be placed on the lower end of the permanent stream impacts to create an impermeable dike for capturing stream flow and sediment that may be held in solution. Stream water will be pumped from the pooled area at the dike and directed to a filter bag located in the uplands where sediment will be collected. Clean stream water will be diverted from the filter bag back to the stream channel below the dike to maintain hydrology during construction. Following construction, temporary fill will be removed from the channel and disturbed stream banks will be returned to original height and slope, matted with a bio -degradable matting, and seeded with a native erosion control and riparian seed mix. 2.

Does this project require a Stormwater Management Plan? ® Yes ❑ No 2c. If this project DOES NOT require a Stormwater Management Plan, explain why: 2d. If this project DOES require a Stormwater Management Plan, then provide a brief, narrative description of the plan: The subject property is located within the Town of Huntersville and will be required to meet the stormwater requirements quality requirements set forth by the Town as well as the Post Construction Stormwater Ordinance which was developed for the Town of Huntersville by Mecklenburg County. Low Impact Develpoment (LID) is required by the Town when more than 12% BUA (built upon area) threshold is exceeded in order to provide additional water quality treatment from runoff. BMP's shall be designed to achieve 85% TSS removal treat 50% of runoff from the 1St inch of rainfall. Below is a summary of the post construction detention requirements for the Town of Huntersville for high density projects. Both Volume Control analysis and Peak Control analysis is required. The post -construction control measures must manage the increase in volume for the 1 -year, 24-hour storm event (Volume Control). In addition, attenuation of the 2 -year and 10 -year, 24-hour storm events are required such that the post -developed flow is less than the pre - developed flow (Peak Control). In order to meet the Town and County stormwater requirements, two (2) stormwater detention ponds have been chosen for the BMP. Each pond will be generally located at the low points of the property and sized appropriately based on the impervious area of the new development. Runoff for each phase of the project will be directed to the stormwater ponds where water will be detained for a period of time before exiting via an outlet control structure designed to reduce the runoff velocity to pre -development conditions. The stormwater ponds will also serve to achive the desired storwmater quality requirements by providing an area for TSS (total suspended solids) to settle prior to exiting the pond. In addition to the ponds, interior bioretention areas andvegetated swales will be implemented to reduce the volume of the post -construction 1 -yr, 24-hour storm event. Western Site: Pond Total Volume: 375,000 cf BMP Volume Controlled: 76,500 cf Flow: Pre- Post- Volume Controlled 2 -year 3.5 cfs 3.43 cfs 135,000 cf 10 -year 27.8 cfs 24.2 cfs 212,000 cf Eastern Site: Pond Total Volume: 455,000 cf BMP Volume Controlled: 79,000 cf Flow: Pre- Post- Volume Controlled 2 -year 3.7 cfs 3.2 cfs 164,000 cf 10 -year 29.0 cfs 25.0 cfs 262,000 cf With the proposed pond facilities, the peak flow for the 2 -year and 10 -year storm events are being reduced below the pre -developed flow condition. Further, the volume in the facility is adequate to manage and detain the BMP volume requirement for the proposed impervious areas. As such, it is the opinion of the engineer that the stormwater management and best management practice requirements of the post -construction condition will be satisfied with the proposed facilities. 2e.

What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical Habitat? CWS performed a data review using North Carolina Natural Heritage Program (NCNHP) Data Explorer on February 26, 2019 to determine the presence of any federally -listed, candidate, endangered, threatened, or critical habitat within the project limits and surrounding area. Based on the NCNHPO review (attached), there are no records for rare species, important natural communities, natural areas, and/or conservation/managed areas within the proposed project boundary. On August 2, 2018 and January 21, 2019 CWS staff scientists performed a pedestrian survey examining the project site for potentially occurring protected species and supporting habitat. The USFWS Endangered, Threatened, FSOC, and Candidate Species website for Mecklenburg County, https://www.fws.gov/raleigh/species/cntylist/mecklenburg.htmi, was consulted prior to the on-site field investigation to determine which protected species are listed as occurring or potentially occurring within the project vicinity. The results of the CWS field investigation are attached in the PETS Report. CWS concludes the proposed project will not affect federally listed species or species are exempt. A copy of the PETS Report was sent to the Asheville USFWS office for concurrence; no response has been received at this time. 6. Essential Fish Habitat (Corps Requirement) 6a.
