The letter specifically addressed three points; 1) an alternative site plan layout proposed by DWQ, 2) stormwater management, and 3) compensatory mitigation. Each point is addressed below, and we have provided supplemental information in Appendices A-C to assist in your review. DWQ Alternative Site Plan (Plan D) Included in this package is an analysis and conceptual drawings of the alternative site layout presented by DWQ at the site meeting on March 5, 2007 and included as a sketch in the letter dated March 9, 2007. The alternative site plan is labeled Plan D and conceptual drawings provided include the site layout, grading, grading profile alignment, and grading profile. Based on the analysis provided by Freeland and Kauffman, Inc., the DWQ conceptual site plan (Plan D) has a number of issues which make it nonviable. The issues addressed in the memo include insufficient parking, unsafe and un-permitable access, safety considerations with parking configuration, grading and retaining walls. You mentioned in your letter that the division staff felt the alternative layout would minimize the need for extensive grading and reduce the overall cut and fill. We examined this and have included for your review cross sectional drawings of the proposed site plan and the alternative site plan presented in your letter for comparison. Please refer to the enclosed memo from Freeland and Kauffman dated March 23, 2007 and conceptual site plan drawings for a complete analysis. The owner of this project has expended considerable time and resources to obtain governmental approval of the currently proposed plan. These efforts have included public hearing review of the project, and issuance of a Conditional Use Permit by Buncombe County, the authority having jurisdiction. Modification of the current design to an approximation of the layout suggestions of DWQ would require a complete redesign of the project, and would require P0. Box 3744 Greenville, South Carolina 29608 (864).271-3040 Fax (864) 235-9299 ~~; ~ ~~~ r i ~/ all permits to be either amended or reissued. This would result in a substantial additional delay to this project, as well as a substantial increase in design costs. Stormwater Management This item was included in the letter presumably because it was discussed as a matter of clarification during the onsite meeting on March 5, 2007. As originally submitted to your office on August 9, 2007, wet detention ponds with littoral shelves are proposed as part of the stormwater management plan. Comnensatory Mitigation Per your request, a fence will be installed along the northern property line in an effort to control dumping into Stream 1. As indicated in the revised compensatory mitigation plan and in a letter to your office dated January, 30, 2007, DWQ and USACOE will be copied on all monitoring reports. While we found that the alternative site plan was not feasible, we do agree that the un-impacted wetlands might be enhanced by directing treated stormwater at non-erosive velocities into the wetland. Stormwater management ponds will be designed to allow for non- erosive discharge into onsite wetlands. Proaosed Site Plan (Plan A) The applicant's proposed site plan (Plan A) has a reduction in the overall impervious surface to approximately 16.7 acres compared to the original site submitted in the permit application which showed approximately 17.6 acres of impervious surface. The applicant applied for and received a parking ratio variance to reduce the required parking ratio from 5/1000s.f of retail space to 4.74/1000 s.f. of retail space. The current proposed site plan also involves a retaining wall at the rear of the building which allows for a reduction of impact to the largest wetland onsite, Wetland C. The result is a reduction of 0.15 acre of impact. In order to ensure that the maximum impact feasible was minimized, the typical delivery truck turn around was eliminated in favor of a one-way dock configuration which requires less space. The applicant has avoided and minimized impacts to Waters of the US to the maximum extent practicable. Alternatives were considered thoroughly prior to submitting the present design and relying on compensatory mitigation. I hope that this addresses all your comments and concerns regarding this project and we can proceed in a timely fashion. If you have any questions, please call me at (864) 271-3040. Thank you for your assistance in this matter. Re pectfully, ~~ , Laura Belanger Environmental Permitting Consultants, Inc. Cc: Mike Ranks, Freeland and Kauffman, Inc. Randy Brown, Wal-Mart Stores, Inc. • • • i r ~ ~ - coq a.a. v ,~ April 11, 2007 To: Laura Belanger Environmental Permitting Consultants, Inc. Re: Wal--Mart Store #9179 NC 280. (Airport Road), Buncombe County, North Carolina Response to NC DFNR Comment Letter (3/9/07) We have reviewed the comment letter provided by NC DENR in regards to the above-re€erenced project, dated 3!9/07. We would specifically like to address Comment No. 1 that was included in this letter, as we understand that you will be providing response to the remaining comments. We have previously submitted a Conceptual Alternate Layout Plan, which is now labeled as Plan C far the purposes of this re-submittal. Upon receipt of the alternate layout, NC DFNR requested that we evacuate another modified version of Plan C. The updated alternate layout, labeled D, as enclosed, was prepared to evaluate the sketch which NC DENR provided. It was NC DENR's belief that Plan D may be a practical and feasible alternative layout for this project, which would minimize the amount of proposed disturbance of the large central wetland on the property. In order to explore this possibility, we have prepared alternate Plan D, and analyzed grading required for the layout_ This plan is an approxima#ion of the sketch provided in NC DENR's 3!9/07 comment letter. Upon completion of our analysis, we have reached the following conclusions: • Insufficient Parking: Plan D provides a tofal of 725 parking spaces, which equates to a ratio. of 3.69 spaces/1000 s.f. This parking ratio is insufficient for a project of this type. As we have previously discussed, the applicable Buncombe County Zoning Ordinance requires a minimum parking ratio for retail developments of 1 space/200 s.f., or 5.0 spaces11000 s.f. We .have previously obtained a variance which allows us to install 209 Went Storoc Avenue - Greernoiltc. South Carolina 29609 • Te~phone 864-23~3~549'X • Fax SF4233-89'15 i i i • • • • only 931 spaces, or 4.74 spaces/1000 s.f., and this is what is provided on Wal-Mart's current proposed-plan, Plan A. This conceptual sife plan layout would result in a large shortage of spaces from this approved variance. Municipalities provide minimum parking ratio requirements for the safety and welfare of the community, and far traffic flow considerations, and a very low parking ratio is contrary to these goals. • Unsafe and Un-permittable Access: Plan D plan shows two entrance drives into the site, with one of these being directly at the comer of the building, in accordance with the NC DENR ske#ch. This entrance would never be permitted in this form by NC DOT, as there is no room for stacking of vehicles waiting to exit the site, and motorists would be forced to make a tum- decision immediately after exiting Airport Road, which is a signifcant safety concern. Additionally, moving this entrance to the location shown on Plan D would offset it from the existing entrance drive across Airport Road from the site, eliminating the possibility of obtaining a traffic signal to control vehicle access to the property. Parking Configuration: while the concep#ual site plan provides approximately 725 parking spaces, only approxima#ely 550 spaces are actually located at the front of the store, where all ingress and egress to the store must take place. The remainder of the spaces are placed to the side and rear of the building. Wal-Mart does have guidelines to insure that customer and associate parking shall generally not be provided past the mid- point of the side building wall. While there are exceptions to this guideline, as noted in the NG DENR letter, customer and associate safety is always the primary consideration the review of any parking configuration. In the instance of Plan D, the rear parking area is completely isolated from the "activity center" of the site, and has no visibility whatsoever from any adjacent roadways or public areas. The parking provided along the entire side of the building in Plan A, the proposed site plan, is clearly better-situated, in that it is connected to the primary parking field, is located along a primary travel-route within the development, and is visible from the public right-af--way. We note that the NC DENR sketch did not show any parking along the front-left side of the building. Our conceptual site plan shows parking in this area, as we are required to provide handicap parking spaces directly in front of the garden center entrance. In an effort to approximate the NC DENR sketch, we ~ kept parking in this area to a minimum, only allowing enough to • provide the required handicap spaces. This is not an acceptable setup to Wal-Mart, as the garden center entry is a vital entrance ~ (one of only three) for customers. and associates, but we feel this ~ plan clearly demonstrates that even with the absolute minimum ~ amount of parking in this area, it will not be possible to avoid ~ disturbance of the large wetland area in the central portion of the site. ~ Additionally, the front parking area is shown angled to the front of ~ the Wal-Mart store in Plan D. This is not an acceptable parking ~ lot design configuration to Wal-Mart, as it results in an unsafe pedestrian crossing condition for a(I access into and out of the ~ store. ~ • Outlot Canficuration: Plan D results in an oddly-shaped outlot • areas. These outlots would ei#her require an additional driveway directly to Airport Road, which NC DOT is unlikely to permit, or r would be provided with very poor access internally from the Wal- ~ Mart property. The result is that the outlots shown on Plan D • would be largely un-marketable due to their shape, separation ~ from the front of the Wal-Mart store, and poor access. As such, the outlots have a reduced financial benefit for development of ~ the shopping center, and would have a negative affect on the ~ aesthetics of the shopping center. • • Grading and Retailing Walls: the NC DENR letter states that the ~ site is presently at the level of Airport Road, and shifting the building and parking lot closer to Airport Road would minimize the ~ need for earthwork operations on the site. A review of the ~ topographic survey reveals that there is approximately 72' of • vertical relief (fall) across the site, and this grade change occurs almost uniformly over the length of the site. This means that the ~ western portion of the site is more than 70' lower than the ~ elevations of Airport Road. By placing the Wal-Mart building * immediately adjacent to Airport Road, as the NC DENR sketch ~ and Plan D shows, the fnished floor elevation of the Wal-Mart structure will very nearly match the adjacent elevations of Airport ~ Road. Of course, the finished floor elevation of the Wal-Mart will ~ be the same on all sides of the building, which means the far left • side of the building will be at nearly the same elevation as Airport Road. We have attached a conceptual grading summary of Plan r D, which has existing contours shown, and labels proposed ~ grades at key points throughout the shopping center. We have ~ noted what the elevation difference will be between the pavement r ~ and existing grades. This plan clearly shows that, with the • building location shown on the NC DENR sketch, we will be ' ' approximately 45 to 4$ higher than existing grades along the ~ majority of the rear of the site. Grading this elevation change in ~ at a 3:1 slope with appropriate maintenance and stabilization ~ benches, this elevation difference of nearly 50' would translate ~ into a slope system approximately 150' to 170' in width. We have sketched the toe of this proposed slope on the attached 11 px17" ~ exhibit, and it is evident that this slope would result in greater ~ wetlands disturbance than the original design, as shown in Plan • A. ~ Replacing this slope with a retaining wall would clearly be ~ impractical, as the height and cost of the wall are simply not ~ realistic from a construction and financial standpoint. ~ The current proposed plan, Plan A, provides long entrance drives ~ which can be sloped steeply, lowering the build-able area" of the ~ site (the building and parking lot), to be much better suited to the • terrain of the property. The fill slopes on the proposed site plan ' r are on the order of 20 in height, while the majority of the fill slopes on the attached conceptual site plan are greater than 45' ~ in height. In addition to the slope taking up more room with the ~ increased height, the conceptual plan would also represen# an additional 20 to 25 vertical feet of fill material which would need to be imported to the properly from elsewhere. The additional cost ~ of this imported fill, and additional land-disturbance on the borrow ~ property, makes this large-scale import both economically • impractical and undesirable. We have provided crass-sections through the currently proposed ~ site plan, as well as the conceptual alternate plan, to help ~ demonstrate the grading challenges of this project. ~ ~ • Miscellaneous Operational Considerations: Plan D results in several other site layout features which are not optimal for ~ operation of the proposed structure. These include poor delivery ~ and truck turn-around access for the side of the store closest to . Airport Road, and poor visibility of the garden center from Airport Road. Most significantly, there will still be wetlands disturbance ~ throughout the site, whether slopes, retaining walls, or both are ~ being utilized. The overall amount of wetlands impacts with a • combination of slopes and retaining walls significantly exceeds i • • those impacts required by Plan A, the proposed Site Plan. If all retaining walls, discounting cost and constructability considerations, fhere will be large portions of the central wetlands area will still be impacted. The cost to import the additional fill and construct retaining walls around all wetlands areas is not an economically viable option. We have provided a version of Plan D with numerical keynotes, which helps to pinpoint many of the issues associa#ed with this conceptual layout. In summary, we have made extensive effort to provide a conceptual plan which approximates the sketch that has been provided by NC DENR. We have prepared and reviewed this plan in good faith, and unfortunately this alternate plan simply does not represent a viable site plan, primarily for the reasons listed above. We have not gone into extensive detail on many of these items, but we will be happy to provide any additional information that might be useful to facilitate fnal review of this project. We continue to believe that the site plan we have proposed (and modified extensively due to discussions with NC DENR and other commenting agencies}, provides the best possible layout for this project, with the minimum amount of required wetlands disturbance. Great efforts have been made to insure that we have considered the reasonable alternatives to the layout for this project, and the proposed site plan treats the wetland areas and streams on this property as conscientiously as possible. Please contact us should you have any additional questions and comments. Thank you. Si rel , M hael R nks, E cc: Randy Brown, Wal-Mart Stores, Ine.

Discussed overall site plan, the USAGE preference for onsite mitigation, and the possibility of mitigating "Wetland E" on a 1:1 ratio through a relocation to and restoration of "Stream 1". March 23, 2006 -Jurisdictional determination issued under Action ID 200630338. A copy is included herein. April 27, 2006 -submitted request for 1 acre of wetland mitigation to the EEP May 3, 2006 -received confirmation of acceptance for 1 acre wetland mitigation through EEP. May 8, 2006 -original individual permit application and conceptual onsite mitigation plan submitted to Cyndi Karoly at the NC DWQ and Dave Baker at the USAGE. A copy is included herein. The applicant proposed to impact 1.93 acres of Waters of the US. July 5, 2006 -public notice issued by the USAGE July 25, 2006 -additional information requested from NC DWQ. Information requested: applicants name, description of waste treatment facilities, clarification of acres of wetlands to be filled, and demonstration of avoidance and minimization. August 11, 2006 -additional information provided to NC DWQ and USAGE. Information requested included individual applicants name, specifications of stormwater treatment, onsite mitigation plan (including 1.41 acres of onsite created wetlands and 500 linear feet of stream relocation and restoration, as well as 0.34 acre onsite wetland preservation, 2.1 acres of onsite upland buffer preservation and the purchase of 1 acre of wetland mitigation from the EEP), and avoidance and minimization. The alternative site layout (Alternative 1) presented involved shifting the site plan slightly north and using a retaining wall along the south/southwestpnrtion of the project in order to avoid impact to "Stream 2" and the associated wetland. This alternative reduced overall wetlands impact by 0.37 acres, but impacted 742 linear feet of stream due to the relocated stormwater management pond. Estimated costs of the retaining walls increased from $260,000 for the originally proposed site plan, to $1.8 million for the Alternative 1 site plan. August 17, 1006 -agency comment letters received from US Fish and Wildlife Service and the North Carolina Wildlife Resources Commission. NCWRC expressed concerns regarding habitat loss in a rapidly growing area, the possibility (although noted unlikely) of bog turtles in Wetland C, and the importance of wetlands to water quality protection. NCWRC requested additional information on avoidance and minimization and the mitigation plan. USFWS had similar comments. In addition, US FWS suggested evaluating the use of parking decks or two story shopping centers to reduce the overall _~ S i footprint and avoid impacts to Waters of the US, or reducing the overall parking ratio to avoid impacts to Wetland E. Suggestions were made to incorporate low-impact development techniques with regards to the storrnwater management plan, due to the percentage of proposed impervious surface. August 31, 2006 -response to agency comments submitted to USACE. Comments regarding the possibility of bog turtle were addressed with the `Protected Species Habitat Assessment' which was provided with the original permit application package. Copies of the complete mitigation plan and demonstration of avoidance and minimization were provided. September 20, 2006 -letter received from NC DWQ indicating that the application was considered incomplete and need more information regarding the "no fill" or "no development" alternative, more specific information on the financial implications of retaining walls vs. fill slopes, and alternative stormwater controls. The letter also mentioned "Re-alignment of the building (as to minimize impacts) and multiple parking facilities with bridges over waters must be fully evaluated as discussed during the onsite meeting". October 11, 2006 -onsite meeting with Tom Walker (USACE), Kevin Barnett (DENR), Brian Tompkins (USFWS), and David McHenry (NCWRC) to review mitigation plan. Discussed the proposed onsite mitigation plan, including revising to eliminate onsite wetland creation in light of the quality of upland habitat surrounding the existing wetlands and reducing the stream restoration component. Brought Tom Walker up to speed on the project as he was taking over for Ronnie Smith, who had previously been the project manager for the USACE. October 20, 2006 - submitted a request for additional wetland credit (total of 1.59 acres) through the EEP October 24, 2006 -revised mitigation plan, cumulative analysis, and additional site layout analysis submitted to DENR and the USACE. Mitigation plan was revised to eliminate onsite wetland creation in favor of additional wetland credit purchased through the EEP. Stream mitigation was downgraded from priority 2 to stream enhancement. In a previous phone conversation with Kevin Barnett, he indicated his notes showed that a layout that would shift the store to the SE corner of the property and provide satellite parking with footbridges in order to avoid impact to Wetland E was brought up during the very first pre-application site visit. This was the plan he was referring to in the Sept. 20, 2006 letter. Per his request to briefly address this layout and why it was not feasible, Alternative 2 (Plan B) was included in this submittal. October 30, 2007 -received confirmation from EEP for acceptance of additional credit request. December 7, 2006 -Received call from Kevin Barnett indicating that project review had come to a halt due to a political inquiry. • January 16, 2007 -request for additional information received from DENR. Information requested included specifications of the treatment of wastewater not accounted for in the stormwater management plan, a request that the mitigation plan be • revised to indicate that NC DWQ would be included with the USACE for success criteria • review, and more specific information regarding Alternative 2. +` January 24, 2007 -faxed copy of revised mitigation plan to Bryan Tompkins (FWS) for . review and comment. January 30, 2007 -additional information provided to John Dorney of NC DWQ along with a summary of previous information supplied and an additional alternative site layout. This submittal included the previously supplied Alternative 1 and Alternative 2 (Plan B) and a new alternative layout, Alternative 3 (Plan C). Alternative 3 (Plan C) involved rotating the building toward the NE corner of the property in an attempt to avoid • impacts to Wetland C associated with the building footprint. This submittal also included • a revised site plan (Plan A) added a retaining wall to the rear of the building to reduce the impact to Wetland C by 0.14 acre and to reduce the overall impervious surface by approximately 1 acre. February 13, 2007 -meeting with John Dorney and Mike Ranks in Raleigh. Discussed alternative site layouts and why they were not feasible. Specifically addressed safety issues of isolated parking, grading in regards to the slope of the entrance drives, and the • necessary height of the retaining wall under Alternative 3 (Plan C) as depicted in Layout i 4 from the January 30, 2007 submittal. February 15, 2007 -Letter received from FWS stating their agreement with the revised • mitigation plan. ', March 5, 2007 - Onsite meeting with John Dorney (NC DWQ), Kevin Barnett (NCDENR) and David McHenry (NCWRC).

[~ (3) The presence of other waters such as intrastate lakes, rivers, streams (including intermittent streams), mudflats, sandflats, . wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds, the use, degradation or destruction of which could • affect interstate commerce including any such waters (check all that apply): ^ (i} which are or could be used by interstate or foreign travelers for recreational or other purposes. ^ (ii) from which fish or shellfish are or could be taken and sold in interstate or foreign commerce. ^ (iii) which are or could be used for industrial purposes by industries in interstate commerce. • (4) Impoundments of waters otherwise defined as waters of the US. (5) The presence of a tributary to a water identified in (1) - (4) above. (6) The presence of territorial seas. (7) The presence of wetlands adjacentZ to other waters of the US, except for those wetlands adjacent to other wetlands. • Rationale for the Basis of Jurisdictional Determination (applies to any boxes checked above). The site contains wetlands as determined by the USACE 1987 Wetland Delineation Manual and is adjacent to stream channels located on the property • that exhibit indicators of ordinary high water marks. The stream channels on the property are unnamed tributaries to the French Broad River which is a Section 10 navigable-in-fact waterway.

The shopping center will consist of a newly constructed Wal-Mart store as well as other commercial structures. Additionally, infrastructure (parking, access drives, t d i s ormwater etent on, etc.) will be constructed to service the new facilities as required by • all applicable Federal, State and local ordinances and regulation. Extensive grading will be required on the site to bring it to an acceptable level with Airport Road. The site has several wetlands, most of which have been highly di sturbed due to past site clearings and soil compaction due to heavy equipment. The proposed development involves the filling of a total of 1.93 acres of wetlands. • The northeastern most wetland, wetland area "E", on the property receives flow from a stormwater pipe installed under Airport Road during its expansion from a two lane f to our lane road. This linear wetland flows west towards the center of the property where it appears to stop without connecting hydrologically to any of the other wetlands or streams on property. The proposed project would pipe the flow from Airport Road north to an existing drainage which ties into an existing stream. Based on the topography of the site, it appears that this was the natural course for the water prior to being diverted during the widening of Airport Road. • Two small wetland areas adjacent to stream 1 which flows along the northern '~ property boundary will be filled during grading. The eastern most, wetland area "A", of h t e two will be filled with 13,148 cu. yards of clean fill, impacting 0.065 acres. The western one, wetland area "B", will be filled partially with 556 cu. yards of clean fill dirt, . impacting 0.01 acres. The largest wetland, wetland area "C", is situated near the center of the property. D ue to the existing grade of the property and the location of the wetland, development of the property is not feasible without filling some portion of the wetland. The proposed project involves the placement of 85,046 cu. yds. of clean fill dirt impacting 1.32 acres of wetland. h T e southwestern most wetland, wetland area "D", flows northwest and joins with stream 2 near the rear of the property. This wetland will be partially filled with 18,056 • cu. yd of clean fill dirt, impacting 0.2 acres of wetland. BLOCK 19 The purpose of the project is to construct a retail shopping center. Extensive site • work will be necessary to prepare the site for level construction. The site was chosen far its proximately to I-26 and to other large retail and commercial developments. BLOCK 20 • Extensive grading will be required to bring the site to an acceptable level with Airport Road. Due to the location of the wetlands, which are spread throughout the d h property, an t e existing grade, it would be impossible to develop the property without impacting Waters of the US. Placing fill in the wetlands is necessary to achieve suitable grade for building. Adjoining Properties Peter Hall PO Box 15368 Asheville, NC 28813 Michael and Wilma Caldwell 5 Machen Rd.

The habitat . assessment was performed in Apri12005 to detemune if habitat for protected species was present on the property. Endangered and threatened species are protected under the Endangered Species Act ES ( A) of 1973 (16 USC 1531-1543). • Endangered species are defined as those plants and animals whose prospects of survival are in immediate danger. Threatened species are those species that may become endangered if conditions related to their existence continue to deteriorate (e.g., loss of suitable habitat). A third • category of concern includes candidate species. Candidate species are those species that may be listed as endangered or threatened in the future (species of concern). Candidate species are not l ll ega y protected under the federal or state ESA. They are provided in this report to account for the • possibility that they might become protected in the near future. EPC's assessment of potential protected species habitat on the Airport Road Wal-Mart • Property was conducted in three (3) phases. The first phase involved the qualitative and • quantitative assessment of general habitat types on the property. 'The second phase consisted of a i rev ew of existing records obtained from federal (US Fish and Wildlife Service) and state (North • Carolina Natural Heritage Program) agencies. Both agencies provided listings of potential protected • species and for Buncombe County. Types of habitat for the protected species were found in various keys and field guides, and on US Fish and Wildlife web pages. The third phase of the assessment consisted of co i h h mpar ng t e abitats identified in phase 1 with those protected species requirements • identified in phase 2. Thus, a determination of critical habitats and the potential for the existence of protected species was conducted. • 2.0 SITE DESCRIPTION • The Airport Road Wal-Mart Property consists of approximately t38 acres ofproperty in Buncombe County, North Carolina. The majority of the site was previously harvested for timber. The site is significantly disturbed with remnant logging debris and rutted out access roads The • . surrounding properties are a mix of undeveloped, residential and commercial land uses. Two • streams with associated wetlands are located on the property as well as several smaller isolated wetlands. Wetlands, streams and isolated wetlands comprise 2.59 acres of the property. Vegetation, soil and hydrologic characteristics observed on the property indicated non-wetland or • disturbed conditions. Non-wetland/waterway areas comprise 35.41 acres of the property. A site location map is provided as Sheet 1 in Appendix 7.1 . The majority of the property is considered disturbed by past land use practices. Existing vegetation consisted primarily of early successional species. Large areas of Smilax sp. and juncos s we p., re present as well as Virginia pine (Pinus virginiana}, sawtooth blackberry (Rubus argutus) • , sweetgum (Liquidambar styrac~zra), tulip poplar (Liriodendron tulipifera), and rhododendron. The . vegetation of the riparian-wetland area consisted of tulip poplar (Liriodendron tzrlipifera) in the t overs ory. The understory consisted of common rush (Juncus effusus) and hazel alder (Alms • serrulata). Protected Species Habitat Assessment Airport Road Wal-Mart EPC Project No. 05eco008 3.0 METHODS 3.1 Habitat Assessment An assessment of the habitat types of the Airport Road Wa1 :Mart Property was determined by performing on-site surveys in Apri12005. Habitat characteristics were based on vegetation type, location in the landscape, past anthropological disturbances, and hydrologic features. TABLE 1 HABITAT ASSESSMENT SUMtrIARY AIRPORT ROAD WAL-MART PROPERTY BUNCOMBE COUNTY, NORTH CAROLINA Habitat T e A roxirnate Acrea e I. Seconda Secessional Forest 35.41 acres 2. Ri arian 2.59 acres Total: 38 acres Two (2) major habitat types were identified on the property. Habitat characteristics were compared to documented requirements for protected species to determine the potential presence of those species on the property. Specific requirements for protected fauna and flora are discussed in Sections 4.2 and 4.3, respectively. 3.2 Agency Review Agency reviews were performed via Internet on websites maintained by the federal and state agencies responsible for the protection of threatened and endangered species. Requests for information regarding the occurrence of protected species on or neaz the project site were directed to the USFWS and North Carolina Natural Heritage Program. The North Carolina Natural Heritage Program Database was examined for the existence of recorded sightings in the project area. The target property was located on the Skyland Quadrant. 3.3 Selection of Protected Species Protected species habitat requirements, as determined from literature review and agency databases were compared to those habitat types identified on the praperty. If protected species habitat requirements corresponded to any of those habitats identified on the property, a qualitative assessment of the potential presence of that species was provided. 4.0 RESULTS 4.1 Habitat Characterization Habitat types on the Airport Road Wal-Mart Property were distinguished by vegetation type, location in the landscape, past disturbances and hydrologic characteristics. Two (2) major habitat types were identified on the property. Secondary secessional growth was found on the majority of the property due to land clearing about five or ten years ago 2 Protected Species Habitat Assessment Airport Road Wal-Mart EPC Project No. OSeco008 (~35 acres). The remainder was wetlands and riparian areas (~3 acres). Habitat characteristics were compared to documented requirements for protected species to determine the potential presence of those species on the property. Specific requirements for protected fauna and flora are discussed in Sections 4.2 and 4.3, respectively. 4.2 Protected Fauna Lists of protected animal species for Skyland Quadrant were provided by the U.S. Fish and Wildlife Service and North Carolina Natural Heritage Program. Listed species, status, and on-site potential are summarized in Table 1. The results of this survey indicate that none of the animal species listed for Buncombe County, Skyland Quadrant, were present on the property.

Species requirements were compared to those habitats observed and on-site potential for each species was assessed. A summary of habitat requirements for each species is provided below: Boe Turtle: The bog turtle "occurs in the mountains and upper piedmont of North Carolina and southern Virginia. These secretive turtles are generally rare and widely scattered. They inhabit damp grassy fields, bogs, and marshes (Martof et. al. 1980.)" When disturbed they quickly bun-ow into ffiud or debris (Martof et. al. 1980). Their potential habitat can be described as spring-fed, soggy, and sunny. Habitat for the bog turtle was not present on the property. No bog turtles were observed during the site assessment. Appalachian Elktoe: "The species has been reported from relatively shallow medium-sized creeks and rivers with cool, well-oxygenated, and moderate- to fast-flowing water. It has been observed in gravelly substrata, often mixed with cobble and boulders; in cracks in bedrock (Gordon 1991); and occasionally in relatively silt-free, coarse, and sandy substrata (J. Alderman, North Carolina Wildlife Resources Commission, personal communication, 1992; personal observations, 1989, 1991). Stability of the substrate appears to be critical to the Appalachian elktoe, and the species is seldom found in stream reaches with accumulations of silt or shifting sand, gravel, or cobble" (USFWS 2002). Habitat for the Appalachian elktoe was not present on the property. No Appalachian elktoe were observed during the site assessment. Tennessee Heelsplitter: Protected Species Habitat Assessment Airport Road Wal-Mart EPC Project No. O~eco008 "The Tennessee heelsplitter is widely distributed in small streams throughout the Tennessee and Alabama River drainages in Alabama, Georgia, Tennessee, North. Carolina, and Virginia; however, it has not been documented in North Carolina since before 1913. The Tennessee heelsplitter is found in small, headwater streams. High densities are most often observed in sand/mud substrates" (http://www.ncwildlife.org/pg07_WildlifeSpeciesCon/pg7blal_12.htm). The habitat for the Tennessee Heelsplitter was not present on property and the Tennessee Heelsplitter was not observed during the site assessment. Gray Myotis: - "Gray bat colonies are restricted entirely to caves or cave-like habitats. During summer the bats are highly selective for caves providing specific temperature and roost conditions. Usually these caves are all located within a kilometer of a river or reservoir. In winter they utilize only deep, vertical caves having a temperature of 6-11 degrees Centigrade. Consequently, only a small proportion of the caves in any area are or can be used regularly. There are nine known caves that are believed to house roughly 95 percent of the hibernating population" (USFWS website). There were no caves or other habitats found on property. No gray myotis were observed during the site assessment. Creeper: "The range of the creeper includes both the Atlantic Slope and the Interior Basin. It is found through the Mississippi and Ohio drainages from Central Texas to Lake Winnipeg, Canada. In the Atlantic Slope it occurs from the Savannah River in South Carolina to the St. Lawrence River in Canada" (Johnson 1970). "This species has been taken from silt, sand, gravel, and mixed substrates. Throughout its range it has been found from headwater streams to large rivers and lakes to a depth of 4 meters" (Gordon and Layzer 1989) (http://www.ncwildlife. org/pg07_WildlifeSpeciesCon/pg7blal_20.htm). The on site potential for the creeper is marginal due to the wide range of habitat types it can live in. Creeper was not observed during the site assessment. Slippervshell Mussel: "This species has a widespread distribution that includes the Upper Mississippi River Basin; Ohio, Cumberland and Tennessee River Subbasins; St. Lawrence River Basin; and Lake Huron, Lake St. Clair, and Lake Erie drainages in Canada."" This species has been found in a wide variety of habitats across its range. In North Carolina, the slippershell mussel inhabits riffle areas with gravel/cobble/boulder substrate. In other locations, the species has been found in small to large streams and lakes; substrates ranging from silt and sand to cobble; and slow to fast currents. It is often found in and around waterwillow, Justicia Americana." (http://www.ncwildlife.org/fs_index_07_conservation.htm) The streams on site did not match the habitat type. The Slipperyshell Mussel was not observed during the site assessment. 4.3 Protected Flora • A list of protected plant species for Skyland Quadrant was provided by the U.S. Fish and Wildlife Service and North Carolina Natural Heritage Program.

Habitat for the bunched arrowhead was not present on the property in the seepage area due to stagnation. No bunched arrowhead was observed on the property. Mountain Sweet Pitcher Plant: This species is native to bogs and a few streamsides in the Blue Ridge Mountains of North Cazolina and South Carolina (USFWS 1990a). Streams on the property were inspected for the presence of this species. Habitat was not present for the mountain sweet pitcher plant in the streams on the property. No specimens of the mountain sweet pitcher plant were observed during the site assessment. 5.0 CONCLUSIONS The conclusions presented herein are based on field surveys and comparisons of habitat requirements of listed protected species of flora and fauna for Buncombe County. No federally protected species were identified on the property. Pratected Species Habitat Assessment Airport Road Wal-Mart EPC Project No. 05eco008 6.0 REFERENCES AND FIELD GUIDES Martoff, B.S., W.M.

Specifically, it addresses avoidance and minimization efforts related to impacts to Waters of the US as required by Section 404(b)1 of the Clean Water Act. Different scenarios and considerations are provided below and give details on why the current location and configuration of the proposed sports complex is as such. A~p~plicant's Name The applicant's name in John E. Clarke, Assistant Vice President of the Wal-Mart Real Estate Business Trust. ' Waste Treatment Facilities The project will utilize awetlands-type retention basin and will be designed in strict accordance with the requirements of Buncombe County and NC DENR. Attached is a memo from Freeland and Kauffman, Inc. sumn~larizing the Stonn Water Management Design. Acres of Wetlands to Be Filled Total acreage of impact is 1.92 acres. During the on-site, pre-application ii~eeting with resource agencies on January 19, 2006, a 2:1 mitigation ratio was requested for all areas with the exceptioof Impact Area "E". Due to the isolated nature of Area "E", which maintains no surface connection with downstream waters, and existing topography on the site which suggests that the flow from the e.-Fisting culvert on Airport Road originally connected to "Stream 1 ", relocation was proposed. During the onsite pre- application meeting, a l:l ratio for Impact Area "E" was discussed, with the proposed ~:C. ~o~~ 3 r~~' ~ ~~ree;~ville, youth Carolina 29608 ~ (864) 271-3040 Fax ~864J 235-92aa ~. mitigation to be the relocation of the flow to the draw located above "Stream 1" with a Priority 2 stream restoration. Based on the discussion at the on-site pre application meeting. a conceptual mitigation plan was created which included 1.41 acres of onsite created wetlands, 0.34 acres of onsite wetland preservation; 1 acre of wetland mitigation from the Ecosystem Enhancement Program, 2.1 acres of onsite upland buffer preservation, and X00 linear feet of onsite stream relocation and restoration. Included in this package is a complete onsite mitigation plan for your review. Avoidance and Minimization No Development The "No Development" scenario is not feasible in this area. Airport Road is a rapidly growing commercial area in close proximity to the Asheville Regional Airport, the Western Carolina Ag Center, I-26, and a number of `big-box" retailers such as Lowe's and Target. The area between Hendersonville and Asheville is rapidly growing. According to recently released estimates from the U.S. Census Bureau, population in the Asheville metro grew by 1.4 % over the last year, adding 5,46 new residents. Among the four counties that make up the metro area, Henderson had the highest rate at 1.8 %. The national average is 0.9 %. These factors contribute to the increasing demand for retail services. Utilizing a Different Site with Less Impacts There were several criteria for the selection of the site: 1) it had to be large enough to support the proposed project, 2) it needed to serve the area between Asheville and Hendersonville, 3) it needed to be located in a commercial area with proximity to I- 26 for easy access, and 4) it needed to be available. Only one other property was available in the immediate vicinity. The property consisted of 12-14 acres, which was not large enough to support the proposed project. Additionally, the site contained 6-8 houses, which would have had to be demolished in order for the site to be developed. Included herein is a map of the vicinity with the location of the proposed project and alternative site. A second map of current Wal-Mart locations is also included. Reduction of On-Site Impacts Every effort was made by the applicant to reduce on-site impacts to the maximum extent possible. The current configuration of the Wal-Mart also lends itself to avoidance acid minimization as much as is practicable. Alternative site layouts were proposed during the design phase. Included herein is a copy of the alternative site layout. In the alternative layout, the use of two retaining walls did allow for an overall reduction of wetland impacts by a total of 0.37 acres, however. by relocating the stormwater detention basin and consolidating the stornzwater management system to one basin rather than two basins, the alternate site layout also impacts 742 linear feet of stream. The proposed site layout does utilize a one retaining wall for reduction of impact by eliminating all impacts to stream 1. Additionally, overall impervious surface was reduced from 18.E acres to 17.6 acres, and outlots were reduced from a total of ~.3 acres to 1.99 acres. Due to the required grading, the retaining wall near the western property boundary would incur a significant increase in cost when compared to the northern retaining wall. The overall cost of both retaini ~ of thesnorthern retaining ~alllbyortself approximately $1.8 million dollars, while the cos is $260.000. Taking into account all of the above mentio~eution of verall amper~iouds suarface avoidance of 742 linear feet of stream impacts, r and outlot acerage, and substantial reduction of costs associated with the construction of the western retaining wall was prefered both ecologically and economically. Existing Design with Mitigation The proposed project includes 1.41 acres of onsite created wetlands, 0.34 acres of onsite wetland preservation, 1 acre ,te u land budffer preservation,nand 500 near feet Enhancement Program, 2.1 acres of onsi p of onsite stream relocation and restoration. The onsite stream relocation and wetland creation was originally proposed during a January 19, 2006 onsite meeting with regulatory official theBulvert on Airport Rd topography of the site, it is believed that the flow coming from which flows into "Area E" originally connected to "Streaml" prior to the road widening project. Thus, we have proposed to relocate the flow and perform a priority 2 stream restoration project onsite. The onsite wetlands creation is designed tutilnzina in aart enhance the higher quality wetlands located near the back of the property P the hydric soils and associated seed bank from the areas to be impacted. A complete on-site mitigation plan is included for your review. All in all, the applicant has avoided and minimized impacts to Waters of the US to the maximum extent practicable. Alternatives were considered thoroughly prior to submitting the present design and relying on compensatory mitigatdi we an°poceed inla addresses all your coomm Vesan dquest ons, p ease call me at (864) 271-3040 pThank you timely fashion.

MITIGATION GOALS AND OBJECTIVES Impact Overview • This plan is being submitted by the Wal-Mart Real Estate Business Trust to mitigate for proposed impacts associated with the construction of the Airport Road Retail Center. The impacts that are being compensated for include 1.6 acres of wetlands and 504 linear feet (0.321 acres) of stream/linear wetland. Stream Mitigation Overview To compensate for the proposed stream impacts, this mitigation plan encompasses a combination of stream relocation/establishment and priority 2 stream enhancement activities. A total of 570 linear feet of stream will be improved by the proposed activities. • All activities are proposed to take place onsite. • The overall goals and purpose of the project are to reconnect and enhance previously disturbed onsite waters. ^ Stream Relocation/Establishment Area (Unit 1 ~ The linear system being impacted enters the property through an existing pipe, the proposed activities would extend the pipe and redirect the waters into an existing ephemeral channel. Approximately, 160 linear feet of ephemeral channel will be enhanced to accommodate the new flow. Prioritv 2 Stream Enhancement Area (Unit 2): As shown in the mitigation overview figures in Appendix 1, the Stream Relocation/Enhancement Reach flows into an existing intermittent/perennial system. Presumably due to previous site activities and development of the watershed, the stream has downcut and is no longer associated with a floodplain. The proposed priority 2 activities will enhance approximately 410 linear feet of stream channel. Wetland Mitigation Overview To compensate for the proposed wetlands impacts, the applicant proposes a combination of onsite wetland creation activities as well as utilizing the EEP program. ^ Wetland Creation Areas (UNIT 3): Two wetland creation areas are proposed to offset the proposed impacts. As shown on figures in Appendix 1, a total of 1.45 acres of wetlands are proposed to be created. 2. BASELINE INFORMATION OF PROJECT SITE Eco-Region -The project is located in the French Broad River Basin (USGS Hydrologic Unit: 06010105). The project area falls within the Blue Ridge EcoRegion. The Blue r i Ridge extends from southern Pennsylvania to northern Georgia, varying from narrow ridges to hilly plateaus to more massive mountainous areas with high peaks. The mostly forested slopes, high-gradient, cool, clear streams, and rugged terrain occur on a mix of igneous, metamorphic, and sedimentary geology. Annual precipitation of over 80 inches can occur on the well-exposed high peaks of the Great Smoky Mountains that reach over 6000 feet above mean sea level. The southern Blue Ridge is one of the richest centers of biodiversity in the eastern U.S. It is one of the most floristically diverse ecoregions, and includes Appalachian oak forests, northern hardwoods, and Southeastern spruce-fir forests. Shrub, grass, and heath balds, hemlock, cove hardwoods, and oak-pine communities are also significant. Location- The Airport Road Property consists of approximately 37.287+/- acres and is located on the west side of Airport Road north of the intersection with I-26 in Buncombe County, North Carolina. The property is bounded by a mobile home park to the north, commercial and residential properties to the west, commercial properties to the south, and Airport Road to the east. A tributary of the French Broad River flows west along a portion of the northern property boundary. Two small wetlands are adjacent to this tributary. A linear wetland runs from Airport Road toward the center of the property, terminating before creating a clear connection with either the tributary or its adjacent wetlands. To the south and near the center of the property is a larger wetland (1.658 acres) which runs northwest to the property boundary where is connects to the first tributary. A second u/n tributary of the French Broad River occurs in the southwest corner of the property and has an associated wetland. The USGS HUC unit is 06010105. A site location map is provided in the Appendix 1. The majority of the site was previously harvested for timber. The site is significantly disturbed with remnant logging debris and rutted out access roads. A protected species habitat assessment was conducted to determine if habitat for protected species was present on the property. No federally protected species were identified on the property. Quantify Wetland Resources - A jurisdictional wetland delineation was conducted on the property identifying wetlands and waterways. Wetlands, streams and isolated wetlands comprise 2.59 acres of the property. The first u/n tributary originates on property and runs east-west along the northern property boundary. The second u/n tributary run northeast near the western property boundary and includes an associated wetland. Two small wetland areas are located adjacent and south of the first tributary. A linear wetland runs east-west from Airport Road towards the center of the property. This wetland receives runoff from stormwater off Airport Road. A large wetland is located in the center of the property and runs northwest to the northern portion of the western property boundary. i Existing Hydrology- Hydrologic characteristics on the property are based on local • rainfall and overflow of the unnamed tributaries of the French Broad River located near the northern boundary of the property. Stormwater run off from Airport Road enters the site from a culvert near the center of the eastern property boundary. • 2 i • • • • Existing Vegetation- The majority of the property is considered disturbed by past land use practices. Existing vegetation consisted primarily of early successional species. • Large areas of Smilax sp. and Juncus effuses were present as well as Virginia pine (Pinars • virginiana}, sawtooth blackberry (Rubus argutus), sweetgum (Liquidambar styraciflara), tulip poplar (Liriodendron tulipifera), hazel alder (Alnus serrulata) and rhododendron. r Existing Soils- The dominant soils within the project area are Tate-Urban Land Complex and Fannin Loam. Prior site disturbance and soil compaction have resulted in gleyed or low-chroma color hydric soils with a hue of SY 5/2 and SY 5/1. A USDA soils map is included in Appendix 1. Slopes on the property ranged from nearly level to 12%. Soils identified on the property included the following: Soil Series and Characteristics Identified in the Soil Survey `for the Ai ort Road Pro Series Symbol Slope Surface Hydric Color Soil? Tate 121U 1-15% slope Nearly No sil cla loam black Fannin 351C 8-15% slope Dark No silt loam brown 3. UNIT 1: Stream Relocation/Establishment Area As shown in pictures included in Appendix 2, the existing ephemeral channel is to be modified and stabilized to handle the flows redirected into the drainage by the proposed pipe. We propose to utilize the same dimension pattern and profile constraints to be utilized in the adjacent, downstream "Priority 2 Stream Enhancement Area". The derivation of the proposed channel parameters is described below in UNIT 2. • Total stream channel relocated and enhanced: approximately 160 linear feet. • The same bank protection and replanting proposed for the "Priority 2 Stream Enhancement Area" will be applied to this reach. 4. UNIT 2: Priority 2 Stream Enhancement Area LEVEL II STREAM ASSESSMENT Data collected during the Level II stream survey included, but not limited to: thalweg, edge of water, water surface, bankfull, top of low bank, width (channel, bankfull), depth (mean, bankfull, max) and slope. All elevations were measured using a surveyor's rod and level. Data collected during the analysis is presented in Appendix 2. • DIMENSION Stream dimension is measured by the cross section data. Key features along the cross section are identified including top of bank, breaks in slope along the cross section, bankfull, edge of water and the thalweg. These measurements are used to determine and calculate the following stream dimensions and ratios; bankfull cross sectional area, bankfull width, mean and max bankfull depth, width/depth ratio, width of flood prone area, entrenchment ratio, and bank height ratio. The width of flood prone area is the width measurement at an elevation twice the maximum bankfull depth. The entrenchment ratio is the width of the flood prone area divided by the bankfull width. The bank height ratio is the height of the low bank divided by the maximum bankfull depth. These measurements help determine the degree of vertical containment of the stream channel. Data Summary sheets for the impaired reach are included in Appendix 2. • PROFILE • The stream channel profile is a description of the gradient and bed facets (riffles, runs, pools and glides) and the spacing of these facets along the length of the stream. Profile data is gathered by performing a longitudinal profile of the stream by surveying the thalweg, edge of water, bankfull and top of low bank (when present) at • least a distance of twenty bankfull widths. Survey data was collected at the top of each facet. A total of 410 linear feet of the unnamed tributary of the French Broad River were assessed. These measurements are used to determine and calculate the following stream dimensions and ratios; average water surface slope, valley slope, facet slopes, pool to pool spacing and pool length. CHANNEL MATERIALS The channel materials data was collected using the Wolman pebble count methods. Channel Material Data Summary sheets are included in Appendix 2. • DATA ANALYSIS Once the field data was collected it was entered RiverMorph and formulas were established to calculate the morphological parameters associated with dimension, profile and channel materials. Estimates of bankfull discharge were determined based on hydraulic geometry, channel roughness and slope using Manning's equation.

REFERENCE REACH As shown in figures included in Appendix 3, the chosen reference reach is located on Little Grove Creek, approximately 51 miles from the project site. This particular reference was selected because: ^ The valley type, slope and soils are similar to the project area. ^ Many years ago, this reach abandoned it's floodplain, widened and has since established a bankfull bench and stable form. ^ The reach has been and will continued to be measured annually to monitor stability. BASELINE INFORMATION for Reference Reach ^ ECOREGION "Tributary K Reference Reach" is located on Little Grove Creek in the Grove Creek watershed of the Saluda River Basin (USGS Hydrologic Unit: 3,050,109). The reference area falls within the Southern Lower Piedmont EcoRegion. A site location map and infrared photo is provided in Appendix 3. ^ SOILS The dominant soils within the project area are Cartecay sandy loam and Toccoa sandy loam associations. A USDA soils map is included in Appendix 3. VEGETATION The forest along Little Grove Creek has been undisturbed for at least 2 decades. The forests maintain a diverse assemblage of tree. Some tree species found in the project area include white oak (Quercus alba), red oak (Quercus rubra), black oak (Qzrercus veluntina), chestnut oak (Qzrercus prinus), maple (Ater rubrum), poplar (Liriodendron tulipifera), hemlock (Tsuga sp.), sycamore (Platanus occidentalis), sweet gum (Liquidambar styraciflua). • LEVEL II STREAM ASSESSMENT of Reference Reach Similar to the project reach a Level II Assessment was performed, data collected during the survey is summarized in Appendix 3. 5 Level II Assessment'.

Data generated from the reference reach was utilized to create dimensionless ratios, which were utilized a parameters for the stream restoration design. RESTORATION PLAN • Restoration figures including proposed channel dimension modifications, bank detail drawings and typical structure plans are included in Appendix 4. • The streams current instability stems from the lack of a functioning flood plain. To stabilize the stream the stream's dimension will be adjusted. o Dimension Adjustments • The existing channel has downcut and is currently widening to create a new flooplain. The proposed activities would speed up the natural progression by modifying the existing banks to establish a functioning bankfull bench and narrowing the existing channel to increase competency. • Across section of the proposed channel is included in Appendix 4. Summaries of the proposed channel dimensions are included in Appendix 4. • As shown in the Typical bank stabilization diagram included in Appendix 4, Bio-D70 matting will be utilized to stabilize the banks and the banks will be vegetated with a combination of herbs and woody vegetation. A list of vegetation proposed to be planted can be found in Appendix 4. • In-stream structures (cross vanes) will be utilized to prevent down cutting. They will be placed at the top of the "Stream Relocation/Enhancement Reach, the top of the "Priority 2 Stream Enhancement Reach" and a the bottom of the "Priority 2 Stream Enhancement Reach". 6 i • • • All of the structures are proposed to be made of rocks, wood or a combination rock and wood.

UNIT 3: Wetland Creation Areas As shown on figures in Appendix 1, the proposed creation areas are downhill from the wetland areas proposed to be impacted and adjacent to an existing wetland. The success of the wetland creation areas relies on providing appropriate hydrology, soils, and vegetation. Planned Hydrology- Due to the existing topography and stream channels that cross the area, this portion of the property is inherently wet. Prior to previous disturbance the existing wetlands were presumably much larger. The hydrology provided to this area should be increased due to the proposed storm water management and grade modifications. The hydrology will be further assisited by minor grading that will result in lowered topography. Planned Soils- The hydric soils (top 12" to 18") of the areas to be impacted will be removed and stockpiled for use in the wetland creation areas. The wetland creation areas will be initially excavated 12" to 18" below proposed grade, and then backfilled with the stockpiled hydric soils. Preserving the naturally occurring hydric soils containing the existing seed bank should promotes the establishment of native hydrophytes and aid in containing necessary hydrology. Planned Vegetation - It is assumed that the seed bank present within the transplanted hydric soils will supply the needed herbs. Woody trees and shrubs will be planted 8 ft. on center. At least 915 trees, shrubs and/or saplings will be planted in the created forested wetland area. Planting schedules for each species and plant category is dependent on dormancy period and expected germination times. It is expected that most of the planting will occur during late fall or early spring periods. Vegetation characteristics for each area will be designed to allow 7 • the highest species diversity and greatest vegetation survival rates. Selected i i i on c compos t species will be dependent on availability of transplants. The florist of the existing wetland areas was analyzed to aid in creating the list of species to • be planted. All selected species will be native to North Carolina and will be • obtained from local nurseries if possible. A vegetation list of species that may be utilized is included in Appendix 4. • 6. Mitigation Work Plan. • All work will be done utilizing current Best Management Practices. • All disturbed riparian areas will be replanted 8 to 12 ft on center with bare root or • containerized woody trees and shrubs. (Species List in Appendix 4). Adaptive Management Clause: • During construction minor changes to the proposed restoration may be made if • more logical or affective means to achieve the projected goals becomes apparent. Construction Schedule • All proposed restoration activities will begin once the final grades have been • acquired for the proposed project and adjacent slopes have been stabilized. The restoration activities will be complete prior to the completion of the construction • of the proposed project. • 7. Monitoring and Success Criteria • 6 monitoring reports over 5 years (a 6-month and 5 annual) will be submitted to • the USACE for review. • • Monitoring reports will include: o Photographs taken from established photo locations that will depict all of • the restoration sites. 0 4 Permanent cross sections will be established along the enhanced • tributaries. Cross sections will be overlaid with previous reports to • determine if the streams dimension is changing. l d d wet an o Survival rates of planted woody vegetation in both riparian an areas will be analyzed utilizing a stem count. o Hydrology success will be monitored utilizing peizometers. • Success Criteria: o Successful stream restoration will be characterized by creating stable • streams, which are not aggrading or degrading. Cross section data will be utilized to demonstrate the stability of the established tributaries. • o Vegetation success on both stream buffer areas and within the created wetland areas, will be qualified by 75% survival. • o Hydrology success within the created wetland areas will be achieved by having soils saturation within 14 inches of the surface for 3 consecutive • • 8 weeks during the growing season. Hydrology will be regularly monitored for level of saturation, using established piezometers. • Contingency Plan: If changes to the streams dimension, pattern or profile are deemed to be negative, leading toward instability, changes to the stream may be made. o Changes may include: • Placement of in-stream structures to stabilize the stream. • Modifying the streams dimension to establish a more appropriate stream dimension. • Stabilizing the stream banks with additional coir matting and vegetation. If the created wetland fails to meet hydrologic standards; the elevations within the created wetland may be adjusted or adjustments may be made to redirect surface flows through the created wetland areas. If the wetlands fail to meet vegetation success the areas will be replanted with different species or hardier stock. Party Responsible for Mitigation Activities: Wal-Mart Real Estate Business Trust.

It is expected that most of the planting will occur during early spring or late fall periods. Vegetation characteristics for the area will be designed to allow the highest species diversity and greatest vegetation survival rates. Selected species will be dependent on availability of transplants. All selected species will be native to North Carolina and will be obtained from local nurseries if possible. The following list includes a selection of species that may be used for the restoration project.

Staff with the North Carolina Wildlife Resources Commission (Commission) visited the project site most recently on July 17, 2006.

The property has excellent early successional habitat for rabbits and other small mammals as well. ~ ~ Bog turtles (State T, Federal T S/A) could occur in the wetlands, particularly wetland area "C", provided there axe downstream water course i . connect ons to other wetlands. Since the azea drains to Lake Julian, they likely do not occur on the property though the possibility of an isolated population in the drainage cannot be di i d ~ sm sse . The lack of bog turtles sited during the applicant's Apri12005 habitat assessment cannot be relied upon as a determination of thei • r occurrence; documenting them would be difficult even with targeted surveys. Therefore, the assertion that suitable habitat for bog turtles is not on the property is incorrect d an request that the file be updated to reflect such. • Similar to habitat values, the wetlands are important to water quality protection in this increasingly urbanized area. Removal of sediment and pollutants fr f om run-o f and attenuation of stonnwater flows by wetlands aze well documented. Headwater streams and wetlands axe particulazly important to watersheds . . • The stream i.'npacts for the project as proposed should be verified. There would be 500 feet of stream relocation with restoration in the northeast f comer o the property, but it is unclear from the jurisdictional map (sheet 5 of 12) where the existing stream channel actually is. This relocation may be wetland area "E", which appears to be a naxrow lin l • ear wet and with a stream channel. However, a stream is not shown here; and only stream 2 which extends from the western property line into the relocation/restoration reach (sheet 10 of 12) is shown on the northern rt f ~ pa o the property. Part of the relocation reach would be a channel creation if there is not a stream channel in wetland area "E", which is probably incorrect. If there is a channel there, then the culvert impacts by lineaz length should be accounted for in total stream im acts p . . • The application does not include a discussion of avoidance and minimization of impacts as directed under Clean Water Act guidelines. During the initial pre-project meetin sev l d ~ g, era a potential project justments were discussed, but the site plan does not seem to reflect these changes with no substantiated explanation of wh i b i y, n part, u lding and pazking reco~gw'ations, headwalls instead of fill slopes, and use of open space in the property's southern corner caxmot reduce wetland impacts Because of the value of the w tl d h . e an s, t ese efforts of minimization axe particularly important and require consideration. ~ Compensatory mitigation for the project is not consistent with current guidelines and would not off- set the project impacts as currently proposed. For restoration and creation of wetlands, ratios of 2:1 • and 3:1, respectively, are used. Therefore, the proposed wetland mitigation leaves a deficit of about 1 acre. The upland buffer preservation and stream restoration augment the overall mitigation ~ proposal, but not much since, in part, the buffer preservation involves one side of a stream channel and the restoration appears to be more avoidance of impacts rather than mitigation. Again, uncertainty remains about the stream channel relocation and culvert impacts. • Information about the wetland creation and stream restoration is needed to complete the review of this project. Presumably the wetland creation would involve grading and replanting with native vegetation, but details were not included. Any wetland creation should attempt to replicate bog • conditions to the extent practicable; though complete replication of bog soils, hydrology, and cover is extremely difficult if not impossible. Further, dimensional design information for the restored stream from regional reference information is needed.

This report is submitted in accordance with the provisions of the Fish • and Wildlife Coordination Act, as amended (16 U.S.C. 661-667e), and section 7 of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531-1543) (Act). Project Description -According to the information provided, the project will involve the . construction of a commercial retail shopping center and associated infrastructure. The proposed project will be constructed on a 38-acre property that contains about 2.32 acres of wetlands and two streams totaling about 1,4491inear feet. The application states that about 1.93 acres of wetlands will be filledlimpacted by the proposed project. • Federally Listed Species -The applicant does not resent evi project area for federally listed species known from Buncomb eCounty. Dunn the s tthe Mr. Tompkins found suitable habitat for the bog turtle (Clemmys muhlenbergii), currently sit r i • r • r federally listed as threatened due to similarity of appearance.a AIthough the provisions of section 7 of the Act do not currently apply to this species, we would greatly appreciate your assistance in determining if any are present within the project impact area. If bog turtles are present, impacts to them should be avoided. In accordance with the Act, it is the responsibility of the appropriate federal agency or its designated representative to review its activities or programs and to identify any such activities or programs that may affect endangered or threatened species or their habitats. If it is determined that the proposed activity may adversely affect any species federally listed as endangered or threatened, formal consultation with this office must be initiated. Alternatives -The application does not include a completed alternatives analysis that demonstrates how the applicant has avoided or minimized the aquatic impacts of the project. We are concerned about the 1.93 acres of wetlands that will be impacted by this project. The applicant has stated that impacts to the 1.93 acres of wetlands cannot be avoided because the wetlands are spread throughout the property. However, we believe there are design alternatives that would provide the high-density shopping experience, thus fulfilling the purpose of the project but eliminating the impact to the jurisdictional wetlands on the property. Alternative designs could include maximizing the space in the parking lot by building a small stacked parking deck, using less ground/wetland space by changing the store layout to a two-story design, and using head walls instead of fill slopes. If a parking deck cannot be constructed, then the size of the parking lot could be reduced to avoid impacts to the linear wetland in the northern section of the property. Fish and Wildlife Resources - As stated above, we are concerned about the direct impacts to the 1.93 acres of wetlands as well as the indirect and cumulative impacts to the remaining streams, wetlands, and forested areas on the subject property. Because the project will convert over 50 percent of the open space to impervious surface (such as roofs, roads, and parking lots), the treatment of storm water leaving the project area and the maintenance of adequate riparian buffers are of particular concern. Therefore, we recommend the following measures to help further minimize project impacts: ~~ `~ Use grassed swales in place of curb and gutter and on-site storm-water management (i.e., bioretention areas) that will result in no net change in the ~" ' hydrology of the watershed. All storm-water outlets should drain through a vegetated upland area prior to reaching any stream Qr wetland area. Sufficient retention designs should be implemented to allow for the slow discharge of storm "Section 4(e) of the [Endangered Species) Act authorizes the treatment of a species (subspecies or population segment) as endangered or threatened even though it is not otherwise listed as endangered or threatened if: (a) The species so closely resembles in appearance an endangered or threatened species that enforcement personnel would have substantial difficulty in differentiating between the listed and unlisted species; (b) the effect of this substantial difficulty is an additional threat to an endangered or threatened species; and (c} such treatment of an unlisted species will substantially facilitate the enforcement and further the policy of the Act" (Federal Register, November 4, 1997). The southern population of the bog turtle is listed as T(S/A) (threatened due to similarity of appearance) because it is similar to the northern population of the bog turtle, which is federally listed as threatened but does not occur in North Carolina. 2 r r r r water, attenuating the potential adverse effects of storm-water surges, thermal spikes; and sediment, nutrient, and chemical discharges. 2. Minimize the amount of impervious surface area that will result from this project. All parking areas should be constructed of a pervious material (i.e., pervious concrete, interlocking/openpaving blocks, etc.). Pervious materials are less likely to absorb and store heat and allow the cooler temperatures of the earth below to cool the pavement. Pervious concrete also requires less maintenance and is less susceptible to freeze/thaw cracking due to large void spaces within the concrete. Pervious parking areas minimize changes to the hydrology of the watershed, can be used to facilitate groundwater recharge, and often eliminate the need for curb and gutter for drainage. 3. Incorporate a rooftop garden or any type of green rooftop into the building construction plans. Green rooftops have many benefits, including: (a) keeping buildings warmer by adding a layer of insulation to the roof and keeping buildings cooler by allowing plants to take in water that evaporates into the atmosphere, resulting in lower heating and cooling bills; (b) reducing the amount and improving the quality ofstorm-water runoff because water is absorbed and filtered through plants and soil; and (c) improving overall air quality by removing particulate matter from the air. This, along with the proposed storm-water runoff collection devices that will be constructed, will dramatically decrease the amount and increase the quality ofstorm-water runoff. 4. Install and maintain stringent measures to control erosion and sediment in order to prevent unnecessary impacts to aquatic resources within and downstream of the project site. Frequent maintenance of these devices is critical to their proper function in order to minimize sediment discharge from the project site. Perimeter erosion-control devices should be installed prior to any on-the-ground activities. 5. Preserve and/or restore forested riparian buffers. Given the close proximity of this project to aquatic resources and the increase of impervious surfaces because of the development, we are concerned about the loss and lack of riparian buffers. We noticed that the applicant is proposing to preserve a portion of the riparian buffer along only one side of the on-site stream. We recommend that the project size be decreased to allow for the preservation of riparian buffers along both sides of the stream and along all preserved wetland areas. Forested riparian buffers, a minimum of 100 feet wide along perennial streams and 50 feet wide along intermittent streams and wetlands, should be created and/or maintained along all aquatic areas. Riparian buffers provide travel corridors and habitat for wildlife displaced by development. In addition, riparian buffers protect water quality by stabilizing stream banks, filtering storm-water runoff, and providing habitat for aquatic and fisheries resources. 3 i r i i r s a a r 6. Install utility lines (i.e., sewer, gas, water) outside the above-recommended buffer widths. All utility crossings should be kept to a minimum, and all utility infrastructure should be kept out of riparian buffer areas. The directional bore stream-crossing method (installation of utilities beneath the riverbed, avoiding impacts to the stream and buffer) should be used for utility crossings. Manholes or similar access structures should not be allowed within buffer areas. Stream crossings should be near perpendicular to stream flow and should be monitored at least every 3 months for maintenance needs during the f rst 24 months of the project and annually thereafter. Sewer lines associated with crossing areas should be maintained and operated at a1i times to prevent discharges to land or surface waters. In circumstances where minimum setbacks cannot be attained, sewer lines shall be constructed of ductile iron or a substance of equal durability. 7. Keep equipment out of streams by operating from the banks in a fashion that minimizes disturbance to woody vegetation. Equipment should be inspected dail and should be maintained to prevent the contamination of surface waters from y leaking fuels, lubricants, hydraulic fluids, or other toxic materials. Ail fuels, lubricants, and other toxic materials should be stored outside the riparian management area of the stream, in a location where the material can be contained. Equipment should be checked for leaks of hydraulic fluids, cooling system liquids, and fuel and should be cleaned before fording any stream. Also, all fueling operations should be accomplished outside the riparian management area. Mitigation - We do not believe the mitigation package (proposed by the applicant to compensate for the adverse impacts of the project) is complete or adequate. No information was provided for the proposed mitigation ratios or for the wetland creation and stream restoratio portion of the mitigation plan. From the information provided, we assume that the a licann' pp t is proposing to provide compensation for the aquatic impacts using a 1: I ratio, which is not consistent with the current mitigation guidelines. According to the "Stream Mitigation Guidelines" endorsed by the Corps, mitigation for aI1 wetland impacts should be calculate d using a 2:1 ratio. Therefore, about 3.86 acres of wetland mitigation credit will be needed to rovid adequate compensation for the impacts of this project to aquatic resources. We recommend e minimizing impacts on the subject property by avoiding or reducing impacts to streams and wetlands, thereby minimizing the amount of mitigation needed and establishing a com rehen ' mitigation plan that provides adequate compensation for the remaining unavoidable im acts save p We recommend that more information, including a detailed alternatives analysis; an anal si all direct, indirect, and cumulative impacts; and a more detailed mitigation packa e that y s of adequately compensates for the adverse impacts of this project, be required before a Co s permit is issued. We recommend that this permit be held in abeyance until this information i presented for review. s We appreciate the opportunity to provide these comments.

Specifically; it addresses avoidance and minimization efforts related to impacts to Waters of the US as required by Section 404(b)1 of the Clean Water Act. Different scenarios and considerations are provided below and give details on why the current location and configuration of the proposed sports complex is as such. Waste Treatment Facilities The project will utilize awetlands-type retention basin and will be designed in strict accordance with the requirements of Buncombe County and NC DENR. Attached is a memo from Freeland and Kauffman, Inc. summarizing the Storm Water Management Design. Acres of Wetlands to Be Filled Total acreage of impact is 1.92 acres. During the on-site, pre-application meeting with resource agencies on January 19, 2006, a 2:1 mitigation ratio was requested for all areas with the exception of Impact Area "E". Due to the isolated nature of Area "E", which maintains no surface connection with downstream waters, and existing topography on the site which suggests that the flow from the existing culvert on Airport Road originally connected to "Stream 1 ", relocation was proposed. During the onsite pre- appIication meeting, a l:l ratio for Impact Area "E" was discussed, with the proposed mitigation to be the relocation of the flow to the draw located above "Stream I" with a Priority 2 stream restoration. P.O. Box 3744 • Greenville, South Carolina 2~6.0__~_•~864)_~71-3nan • Fay rQadl_~~~_o9nn Based on the discussion at the on-site pre application meeting, a conceptual mitigation plan was created which included 1.41 acres of onsite created wetlands, 0.34 acres of onsite wetland preservation, 1 acre of wetland mitigation from the Ecosystem Enhancement Program, 2.1 acres of onsite upland buffer preservation, and X00 linear feet of onsite stream relocation and restoration. A complete mitigation plan was submitted August 11, 2006. Alternatives Analysis No Development The "No Development" scenario is not feasible in this area. Airport Road is a rapidly growing commercial area in close proximity to the Asheville Regional Airport, the Western Carolina Ag Center, I-26, and a number of `big-box" retailers such as Lowe's and Target. The area between Hendersonville and Asheville is rapidly growing. According to recently released estimates from the U.S. Census Bureau, population in the Asheville metro grew by 1.4 % over the last year, adding 5,465 new residents. Among the four counties that make up the metro area, Henderson had the highest rate at 1.8 %. The national average is 0.9 %. These factors contribute to the increasing demand for retail services. Utilizing a Different Site with Less Impacts There were several criteria for the selection of the site: 1) it had to be large enough to support the proposed project, 2) it needed to serve the area between Asheville and Hendersonville, 3) it needed to be located in a commercial area with proximity to I- 26 for easy access, and 4) it needed to be available. Only one other property was available in the immediate vicinity. The property consisted of 12-14 acres, which was not large enough to support the proposed project. Additionally, the site contained 6-8 houses, which would have had to be demolished in order for the site to be developed. Included herein is a map of the vicinity with the location of the proposed project and alternative site. A second map of current Wal-Mart locations is also included. Reduction of On-Site Impacts Every effort was made by the applicant to reduce on-site impacts to the maximum extent possible. The current configuration of the Wal-Mart also lends itself to avoidance and minimization as much as is practicable. Alternative site layouts were proposed during the design phase. Included herein is a copy of the alternative site layout. In the alternative layout, the use of two retaining walls did allow for an overall reduction of wetland impacts by a total of 0.37 acres, however, by relocating the stormwater detention basin and consolidating the stormwater management system to one basin rather than two basins, the alternate site layout also impacts 742 linear feet of stream. The proposed site layout does utilize a one retaining wall for reduction of impact by eliminating all impacts to stream 1. Additionally, overall impervious surface was reduced from 18.5 acres to 17.6 acres, and outlots were reduced from a total of 3.3 acres to 1.99 acres. Due to the required grading, the retaining wall near the western property boundary would incur a significant increase in cost when compared to the northern retaining wall. The overall cost of both retaining walls for the alternate site layout is approximately $1.8 million dollars, while the cost of the northern retaining wall by itself is $260,000. Taking into account all of the above mentioned factors, it was determined that the avoidance of 742 linear feet of stream impacts, reduction of overall impervious surface and outlot acreage, and substantial reduction of costs associated with the construction of the western retaining wall was preferred both ecologically and economically. Existing Design with Mitigation The proposed project includes 1.41 acres of onsite created wetlands, 0.34 acres of onsite wetland preservation, 1 acre of wetland mitigation from the Ecosystem Enhancement Program, 2.1 acres of onsite upland buffer preservation, and 500 linear feet of onsite stream relocation and restoration. The onsite stream relocation and wetland creation was originally proposed during a January 19, 2006 onsite meeting with regulatory officials. Based on the existing topography of the site, it is believed that the flow coming from the culvert on Airport Rd., which flows into "Area E" originally connected to "Streaml" prior to the road widening project. Thus, we have proposed to relocate the flow and perform a priority 2 stream restoration project onsite. The onsite wetlands creation is designed to increase and enhance the higher quality wetlands located near the back of the property utilizing in part the hydric soils and associated seed bank from the areas to be impacted. A complete on-site mitigation plan was submitted August 1 1, 2006. Comments Received FWS and NCWRC In a letter dated July 28, 2006 NC Wildlife Resources Commission comments on several aspects of the permit application. In a letter dated August 2, 2006, Fish and Wildlife Service made similar comments. Both sets of comments are addressed below. • Both FWS and NCWRC first addressed the issue of federally listed species on the target property. EPC, Inc. completed a Protected Species Habitat Assessment for the target property in April, 2006. This was submitted with the permit application. Based on our findings, no bog turtles exist on the property. Bog turtle habitat is dependant on connections to other wetlands, and the wetlands on the property do not fit that description as they drain into aman-made lake. While we do concur that wetlands in area "C" could prove suitable if a downstream water course connection to other wetlands was present, we do feel that the presence of an isolated population highly unlikely. • Both FWS and NCWRD requested an alternatives analysis. The requested information is provided above. Additionally, supporting documentation regarding the cost of retaining walls has been supplied in the form of a memo from the site engineers. • FWS addressed both concerns and suggestions for the treatment of stormwater leaving the project site. The project will utilize a wetlands- type retention basin and will be designed in strict accordance with the requirements of Buncombe County and NC DENR. o Appropriate erosion and sediment control measures will be taken throughout all phases of construction. o All riparian buffers outside of the area of construction are going to be restored or preserved as part of the on-site mitigation plan. • FWS and NCWRC requested a complete mitigation plan. Mitigation has been addressed in the "Onsite Mitigation Plan, Airport Road Retail Center" dated August 2006 and submitted August 11, 2006. All in all, the applicant has avoided and minimized impacts to Waters of the US to the maximum extent practicable. Alternatives were considered thoroughly prior to submitting the present design and relying on compensatory mitigation. I hope that this addresses all your comments and concerns regarding this project and we can proceed in a timely fashion. If you have any questions, please call me at (864) 271-3040.

We would like to request that the permit review process be reactivated. Avoidance and Minimization No Development The "No Development" scenario is not feasible in this area. Airport Road is a rapidly growing commercial area in close proximity to the Asheville Regional Airport, the Western Carolina Ag Center, I-26, and a number of `big-box" retailers such as Lowe's and Target. The area between Hendersonville and Asheville is rapidly growing. According to recently released estimates from the U.S. Census Bureau, population in the Asheville metro grew by 1.4 % over the last year, adding 5,465 new residents. Among the four counties that make up the metro area, Henderson had the highest rate at 1.8 %. The national average is 0.9 %. These factors contribute to the increasing demand for retail services. The corridor in which this parcel is located has been specifically targeted by the state for this kind of development. Infrastructure, such as the road widening of NC 280 and I-26, makes this area the logical location for the retail services demanded by the growing population. The infrastructure provides the foundation for commercial development and allows such development to remain consolidated in one area. Under the No Development scenario, the project would not take place and the proposed retail center would not be built. No impacts to Waters of the US would occur, and consequently, no on site restoration would occur. Investments in property, design, and time will be lost, along with the potential for approximately 350* new jobs. The project would relocate to a new site that would possibly require upgrades to existing infrastructure. The expansion of roads to handle traffic would then allow for additional smaller developments to move in, creating a new commercial area else ware in the region. Reduction of On-Site Impacts Every effort was made by the applicant to reduce on-site impacts to the maximum extent possible. The current configuration of the Wal-Mart also lends itself to avoidance and minimization as much as is practicable. Alternative site layouts were proposed during the design phase. Included herein are copies of two alternative site layouts. Alternative 1: In the first alternative layout, the use of two retaining walls did allow for an overall reduction of wetland impacts by a total of 0.37 acres, however, due to the relocation of the stormwater detention basin, the alternate site layout also impacts 742 linear feet of stream. The stormwater management needs to be located at a lower elevation than the developed area. Therefore, the logical locations for the ponds are at the lowest points on the property. If the area behind the western retaining wall was utilized for a detention pond, it would still be necessary for a second pond in order to meet the detention requirements for the site. Storm drain would have to be punched through the retaining wall and be routed to the proposed pond. In order to install the storm drain, a fair amount of wetlands would still have to be impacted. Thus impacts would exist on the stream as well as the western wetland area "D". The configuration of the ponds on the alternative layout shows the least amount of impact possible. Due to the required grading, the retaining wall near the western property boundary would incur a significant increase in cost when compared to the northern retaining wall. The overall cost of both retaining walls for the alternate site layout is approximately $1.8 million dollars, while the cost of the northern retaining wall by itself is $260,000. From a strictly economic standpoint, the $1.5 million (592% increase in cost) is not viable for the scope of the project and represents a dramatic increase in overall cost. Alternative 2: This alternative involves rotating the building so that the side is oriented toward Airport Road and utilizing the out lots as satellite parking with a span over Wetland "E". As you can see from the site plan, the re-orientation of the building and the spanning of Wetland "E" does not allow for adequate parking or access to the front of the building. Commercial centers are required by law to provide a certain number of handicapped parking spaces with easy access to the front of the store for patrons with disabilities. Additionally, the grading requirements for the site still exist, so retaining walls would be necessary, along with the span for Wetland Area "E". This layout would not be feasible due to the lack of adequate parking, lack of adequate access to the front of the store and r S r additional costs associated with abridge/span and the multiple retaining walls needed to avoid impact to "Wetland Area E". The proposed site layout does utilize one retaining wall for reduction of impact by eliminating all impacts to stream 1. Additionally, overall impervious surface was reduced from 18.5 acres to 17.6 acres, and outlots were reduced from a total of 3.3 acres to 1.99 acres. Taking into account all of the above mentioned factors, it was determined that the avoidance of 742 linear feet of stream impacts, reduction of overall impervious surface and outlot acreage, and substantial reduction of costs associated with the construction of the western retaining wall was preferred both ecologically and economically. Existing Design with Mitigation The proposed project includes 1.41 acres of onsite created wetlands, 0.34 acres of onsite wetland preservation, 1 acre of wetland mitigation from the Ecosystem Enhancement Program, 2.1 acres of onsite upland buffer preservation, and 500 linear feet of onsite stream relocation and enahcement. An onsite mitigation meeting took place October 11, 2006 with NCDENR, USACE, FWS, and NCWRC. Based on discussions regarding the proposed mitigation plan, we have revised the plan to eliminate the priority 2 stream restoration in favor of stream enhancement and spot stabilization, due to the lack of buffer available. We have also ensured that the outflow from the stormwater management ponds will flow into the created wetland areas to add to the over hydrology of the area. A complete revised on-site mitigation plan is included for your review. All in all, the applicant has avoided and minimized impacts to Waters of the US to the maximum extent practicable. Alternatives were considered thoroughly prior to submitting the present design and relying on compensatory mitigation. I hope that this addresses all your comments and concerns regarding this project and we can proceed in a timely fashion. If you have any questions, please call me at (864) 271-3040.

MROSPCN008 PREPARED FOR: WAL-MART REAL ESTATE BUISNESS TRUST PREPARED BY: ENVIRONMENTAL PERMITTING CONSULTANTS 125 WEST STONE AVENUE (29609) POST OFFICE BOX 3744 GREENVILLE, SOUTH CAROLINA 29608 OCTOBER 2006 The State of North Carolina's 401 Water Quality Certifications require that the Division of Water Quality confirm that the project it is evaluating "does not result in cumulative impacts, based upon past or reasonably anticipated future impacts, which cause or will cause a violation of downstream water quality standards". The Division of Water Quality evaluates cumulative impacts based on the guidelines of the "Draft Internal Policy, Cumulative Impacts and the 401 Water Quality Certification and Isolated Wetland Program. NC Division of Water Quality, October 3, 2002, Version 1.6". Based on these guidelines, DWQ's policy provides for three levels of analysis. For projects involving only small amounts of added impervious surface or occurring in heavily developed areas, a "Generic Description" of the project's possible cumulative impacts will be required. If the project will involve a significant increase in impervious surface (generally 20% or more), but is located near existing roads and development, a "Qualitative Analysis" will be required. The highest level, the "Quantitative Analysis", is required where a project is significant in size and likely to stimulate growth in the area. DWQ's policy provides that it is applicable to private development projects, although it recognizes that many of the projects are unlikely to cause cumulative impacts. DWQ recognizes that private development projects are most likely cause cumulative impacts when they are "1) relatively large, 2) involve commercial development, and 3) occur in otherwise relatively undeveloped landscapes with an impact on regional growth patterns". For the Airport Road Retail Shopping Center project, DWQ has determined that a qualitative analysis of the potential cumulative impacts of the project would be appropriate in terms of determining the effects on downstream water quality. To determine potential cumulative impacts, this project was reviewed for any growth stimulating effects that could potentially foster downstream impacts on water quality. Factors taken into consideration include the project size, its nature, and its proximity to the developed local landscape. Project Description The site is located on the west side of Airport Road north of the intersection with I-26 in Arden, NC. The property is bounded by a mobile home park to the north, commercial and residential properties to the west, commercial properties to the south, and Airport Road to the east. The proposed project would create a total of approximately 17.8 acres of impervious surface on the 37.287+/- acre site. The overall project involves the construction of a commercial retail shopping center. The shopping center will consist of a newly constructed Wal-Mart store as well as other commercial structures. Additionally, infrastructure (parking, access drives, stormwater detention, etc.) will be constructed to service the new facilities as required by all applicable Federal, State and local ordinances and regulation. ~ Extensive grading will be required on the site to bring it to an acceptable level with Airport Road. The site has several wetlands, most of which have been highly disturbed . due to past site clearings and soil compaction due to heavy equipment. The proposed development involves the filling of a total of 1.93 acres of wetlands. r Project Area Description The project is located in Arden, North Carolina. Arden is located in south Buncombe County along I-26, in between Hendersonville, NC and Asheville, NC. Arden, NC is home of the Asheville Regional Airport, which is located approximately 1 mile from the proposed project site. Arden is a rapidly growing area due to its proximity to both Hendersonville and Asheville. Hendersonville and Asheville have solid positions as top retirement destinations, repeatedly appearing on lists of top place from sources such as Modern Maturity, HARP, RelocateAmerica.com and Baryons. Hendersonville is ranked number five -- Asheville is number three and Brevard is number six -- in a just released book by Warren Bland, Retire in Style, 60 Outstanding Places across the USA and Canada. Additionally, Asheville was listed by Rolling Stones magazine as the "freak capitol of the Untied States" and by National Geographic Adventure as a top 10 adventure town. The diverse nature of the area has contributed to the growing population. Watershed Description The project is located within the French Broad River Basin. The onsite streams are unnamed tributaries of Lake Julian, which is classified as "C" waters. Class "C" waters are defined as "freshwaters protected for secondary recreation, fishing, aquatic life including propagation and survival, and wildlife." The current condition of Lake Julian is listed as "Fully Supporting" based on the 2000 French Broad River Basinwide Water Quality Plan. Lake Julian is monitored by Carolina Power and Light Company. Comparison of chemistry characteristics from data obtained in 1992 and 1996 show that the lake has remained relatively unchanged. In addition, a special study of trace elements preformed in 1995 showed that trace elements "were comparable to background concentrations or slightly above background concentrations." Project Induced Growth The proposed project is not likely to induce adjacent development as much of the surrounding area is already developed. The corridor in which this parcel is located has been specifically targeted by the state for this kind of development. Infrastructure, such as the road widening of NC 280 and I-26, makes this area the logical location for the retail services demanded by the growing population. The infrastructure provides the foundation for commercial development and allows such development to remain consolidated in one area. This particular parcel is one of the last remaining undeveloped parcels and is surrounded by other "big-box" developments. Based on the developed nature of the surrounding area and the overall nature and purpose of the project, it is not believed that the project will induce adjacent developments that would have impacts on downstream water quality. Summary Wal-Mart Real Estate Business Trust proposes to develop this project in accordance with likely conditions in the 401 Water Quality Certification and the previously received 404 permit authorizations. The purpose of implementing these guidelines is to protect the downstream water quality in the area of the project. Based on the projects proximity to I- 26, Airport Road, the Asheville Regional Airport, as well as the surrounding commercial development, the applicant does not believe that any potential effects on growth will occur due to the Airport Road Retail Shopping Center project.

Stream 1Vlitigation Overview • • To compensate for the proposed stream impacts, this mitigation plan encompasses . a combination of stream relocation establishment and stream enhancement activities. A total of 570 linear feet of stream will be improved by the proposed activities. • • All activities are proposed to take place onsite. • The overall goals and purpose of the project are to reconnect and enhance previously disturbed onsite waters. ^ Stream Relocation/Establishment Area (Unit 1Z The linear system being impacted enters the property through an existing pipe, the proposed activities would extend the pipe and redirect the waters into an existing ephemeral channel. Approximately, 1601inear feet of ephemeral channel will be enhanced to accommodate the new flow. r Stream Enhancement Area (Unit 2): As shown in the mitigation overview figures in Appendix 1, the Stream Relocation/Enhancement Reach flows into an existing intermittent/perennial system. The existing stream contains large amounts of solid waste and debris, as well as several areas of bank failure. The proposed activities will enhance approximately 410 linear feet of stream channel. Wetland Mitigation Overview To compensate for the proposed wetlands impacts, the applicant proposes a combination of onsite wetland creation activities as well as utilizing the EEP program. ^ Wetland Creation Areas (UNIT 3): Two wetland creation areas are proposed to offset the proposed impacts. As shown on figures in Appendix 1, a total of 1.45 acres of wetlands are proposed to be created. 2. BASELINE INFORMATION OF PROJECT SITE Eco-Region -The project is located in the French Broad River Basin (USGS Hydrologic Unit: 06010105). The project area falls within the Blue Ridge EcoRegion. The Blue Ridge extends from southern Pennsylvania to northern Georgia, varying from narrow ridges to hilly plateaus to more massive mountainous areas with high peaks. The mostly • forested slopes, high-gradient, cool, clear streams, and rugged terrain occur on a mix of . igneous, metamorphic, and sedimentary geology. Annual precipitation of over 80 inches can occur on the well-exposed high peaks of the Great Smoky Mountains that reach over 6000 feet above mean sea level. The southern Blue Ridge is one of the richest centers of • biodiversity in the eastern U.S. It is one of the most floristically diverse ecoregions, and includes Appalachian oak forests, northern hardwoods, and Southeastern spruce-fir forests. Shrub, grass, and heath balds, hemlock, cove hardwoods, and oak-pine communities are also significant. Location- The Airport Road Property consists of approximately 37.287+/- acres and is located on the west side of Airport Road north of the intersection with I-26 in Buncombe County, North Carolina. The property is bounded by a mobile home park to the north, • commercial and residential properties to the west, commercial properties to the south, and Airport Road to the east. A tributary of the French Broad River flows west along a portion of the northern property boundary. Two small wetlands are adjacent to this S tributary. A linear wetland runs from Airport Road toward the center of the property, • terminating before creating a clear connection with either the tributary or its adjacent wetlands. To the south and near the center of the property is a larger wetland (1.658 acres) which runs northwest to the property boundary where is connects to the first • tributary. A second u/n tributary of the French Broad River occurs in the southwest corner of the property and has an associated wetland. The USGS HUC unit is 06010105. A site location map is provided in the Appendix 1. • The majority of the site was previously harvested for timber. The site is significantly disturbed with remnant logging debris and rutted out access roads. A protected species habitat assessment was conducted to determine if habitat for protected species was • present on the property. No federally protected species were identified on the property. Quantify Wetland Resources - A jurisdictional wetland delineation was conducted on the property identifying wetlands and waterways. Wetlands, streams and isolated • wetlands comprise 2.59 acres of the property. The first u/n tributary originates on • property and runs east-west along the northern property boundary. The second u/n tributary run northeast near the western property boundary and includes an associated wetland. Two small wetland areas are located adjacent and south of the first tributary. A • linear wetland runs east-west from Airport Road towards the center of the property. This wetland receives runoff from stormwater off Airport Road. A large wetland is located in the center of the property and runs northwest to the northern portion of the western property boundary. Existing Hydrology- Hydrologic characteristics on the property are based on local rainfall and overflow of the unnamed tributaries of the French Broad River located near the northern boundary of the property. Stormwater run off from Airport Road enters the site from a culvert near the center of the eastern property boundary. • 4 r r Existing Vegetation- The majority of the property is considered disturbed by past land use practices. Existing vegetation consisted primarily of early successional species. Large areas of Smilccr sp. and Jzznczrs effizses were present as well as Virginia pine (Pinzrs virginiana), sawtooth blackberry (Rzrbzzs ar,;zrtus), sweetgum (Ligzridambar stvrac~zra), tulip poplar (Liriodendron tz~lipifera), hazel alder (Alnz~s serrzrlata) and rhododendron. Existing Soils- The dominant soils within the project area are Tate-Urban Land Complex and Fannin Loam. Prior site disturbance and soil compaction have resulted in gleyed or low-chroma color hydric soils with a hue of SY 5/2 and SY 5/1. A USDA soils map is included in Appendix 1. Slopes on the property ranged from nearly level to 12%. Soils identified on the property included the following: SoilSeries~and'CharacteristicsTdentified irithe SoiI~Survey:for the ' A- ort Road Pro e ~ ~ ~ `" Series Symbol Slope Surface Hydric Color Soil? Tate 121 U 1-15% slope Nearly No sil cla loam black Fannin 351C 8-15% slope Dark No silt loam brown 3. UNIT 1: Stream Relocation/Establishment Area • As shown in pictures included in Appendix 2, the existing ephemeral channel is to be modified and stabilized to handle the flows redirected into the drainage by the proposed pipe. We propose to utilize the same dimension pattern and profile constraints to be utilized in the adjacent, downstream "Stream Enhancement Area". The derivation of the proposed channel parameters is described below. • Total stream channel relocated and enhanced: approximately 1601inear feet. • The same bank protection and replanting proposed for the "Stream Enhancement Area" will be applied to this reach. 4. UNIT Z: Stream Enhancement Area LEVEL II STREAM ASSESSMENT • Data collected during the Level II stream survey included, but not limited to: thalweg, edge of water, water surface, bankfull, top of low bank, width (channel, bankfull), depth ' (mean, bankfull, max) and slope. All elevations were measured using a surveyor s rod and level. Data collected during the analysis is presented in Appendix 2. • DIMENSION . Stream dimension is measured by the cross section data. Key features along the cross • section are identified including top of bank, breaks in slope along the cross section, bankfull, edge of water and the thalweg. i These measurements are used to determine and calculate the following stream dimensions and ratios; bankfull cross sectional area, bankfull width, mean and max bankfull depth, width/depth ratio, width of flood prone area, entrenchment ratio, and bank height ratio. The width of flood prone area is the width measurement at an elevation twice the maximum bankfull depth. The entrenchment ratio is the width of the flood prone area divided by the bankfull width. The bank height ratio is the height of the low bank divided by the maximum bankfull depth. These measurements help determine the degree of vertical containment of the stream channel. Data Summary sheets for the impaired reach are included in Appendix 2. PROFILE The stream channel profile is a description of the gradient and bed facets (riffles, runs, pools and glides) and the spacing of these facets along the length of the stream. Profile data is gathered by performing a longitudinal profile of the stream by surveying the thalweg, edge of water, bankfull and top of low bank (when present) at least a distance of twenty bankfull widths. Survey data was collected at the top of each facet. A total of 410 linear feet of the unnamed tributary of the French Broad River were assessed. These measurements are used to determine and calculate the following stream dimensions and ratios; average water surface slope, valley slope, facet slopes, pool to pool spacing and pool length. CHANNEL MATERIALS The channel materials data was collected using the Wolman pebble count methods. Channel Material Data Summary sheets are included in Appendix 2. • DATA ANALYSIS Once the field data was collected it was entered RiverMorph and formulas were established to calculate the morphological parameters associated with dimension, profile and channel materials. Estimates of bankfull discharge were determined based on hydraulic geometry, channel roughness and slope using Manning's equation.

REFERENCE REACH As shown in figures included in Appendix 3, the chosen reference reach is located on Little Grove Creek, approximately 51 miles from the project site. This particular reference was selected because: ^ The valley type, slope and soils are similar to the project area. ^ Many years ago, this reach abandoned it's floodplain, widened and has since established a bankfull bench and stable form. ^ The reach has been and will continued to be measured annually to monitor stability. BASELINE INFORMATION for Reference Reach ^ ECOREGION "Tributary K Reference Reach" is located on Little Grove Creek in the Grove Creek watershed of the Saluda River Basin (USGS Hydrologic Unit: 3,050,109). The reference area falls within the Southern Lower Piedmont EcoRegion. A site location map and infrared photo is provided in Appendix 3. ^ SOILS The dominant soils within the project area are Cartecay sandy loam and Toccoa sandy loam associations. A USDA soils map is included in Appendix 3. VEGETATION The forest along Little Grove Creek has been undisturbed for at least 2 decades. The forests maintain a diverse assemblage of tree. Some tree species found in the project area include white oak (Qz~erczrs alba), red oak (Quercus rubs), black oak (Quercus velzmtina), chestnut oak (Quercus prinus), maple (Ater rubrum), poplar (Liriodendron tzrlipifera), hemlock (Tsuga sp.), sycamore (Platanus occidentalis), sweet gum (Ligzridambar sryrac~ua). • LEVEL II STREAM ASSESSMENT of Reference Reach Similar to the project reach a Level II Assessment was performed, data collected during the survey is summarized in Appendix 3. 7 i • • • r r i Level II Assessment Summary of reference reach K on Little Grove Creek Parameter Pro'ect Reach Ros en Stream T e B4c - C4 Drainage Area (sq. mi.) 2.073 Bankfull Width ft. 17.9 Mean Bankfull De th ft. 1.74 Width/De th Ratio 10.31 Bankfull Areas . ft. 31.3 Entrenchment Ratio 3.62 Water Surface Sloe % 0.005 Sinuosi K A rox.1.6 D50 mm 1.75 Bankfull Dischar e cfs 154 ** A more comprehensive list of stream variables is included in Appendix 3.

RESTORATION PLAN Restoration figures are included in Appendix 4. • Work in the "Stream Enhancement Area" will involve the removal of all solid waste debris within the existing channel. In addition, spot stabilization using hand tools and Bio-D70 matting will occur in areas showing signs of bank failure. More extensive bank sloping will not take place due to the proximity of the stream to the property line. o Dimension Adjustments - "Stream Relocation/Establishment Reach" • Across section of the proposed channel is included in Appendix 4. Summaries of the proposed channel dimensions are included in Appendix 4. • As shown in the Typical bank stabilization diagram included in Appendix 4, Bio-D70 matting will be utilized to stabilize the banks and the banks will be vegetated with a combination of herbs and woody vegetation. A list of vegetation proposed to be planted can be found in Appendix 4. • In-stream structures (cross vanes) will be utilized to prevent down cutting. They will be placed at the top and bottom of the "Stream Relocation/Enhancement Reach. • All of the structures are proposed to be made of rocks, wood or a combination rock and wood. 8 Proposed Channel Parameters Parameter Pro'ect Reach Ros en Stream T e Bob - E4b Drainage Area (sq. mi.) 0.0697 Bankfull Width ft. 4.4 Mean Bankfull De th ft. 0.51 Width/De th Ratio 8.58 Bankfull Areas . ft. 2.24 Entrenchment Ratio 3.62 Water Surface Sloe % 0.023 Sinuosi K A rox.1.3 Bankfull Dischar e cfs 7.84 ** A more comprehensive list of stream variables is included in Appendix 4. 5. UNIT 3: Wetland Creation Areas As shown on figures in Appendix 1, the proposed creation areas are downhill from the wetland areas proposed to be impacted and adjacent to an existing wetland. The success of the wetland creation areas relies on providing appropriate hydrology, soils, and vegetation. Planned Hydrology- Due to the existing topography and stream channels that cross the area, this portion of the property is inherently wet. Prior to previous disturbance the existing wetlands were presumably much larger. The hydrology provided to this area should be increased due to the proposed storm water management and grade modifications. The hydrology will be further assisited by minor grading that will result in lowered topography. Planned Soils- The hydric soils (top 12" to 18") of the areas to be impacted will be removed and stockpiled for use in the wetland creation areas. The wetland creation areas will be initially excavated 12" to 18" below proposed grade, and then backfilled with the stockpiled hydric soils. Preserving the naturally occurring hydric soils containing the existing seed bank should promotes the establishment of native hydrophytes and aid in containing necessary hydrology. Planned Vegetation - It is assumed that the seed bank present within the transplanted hydric soils will supply the needed herbs. Woody trees and shrubs will be planted 8 ft. on center. At least 915 trees, shrubs and/or saplings will be planted in the created forested wetland area. Planting schedules for each species and plant category is dependent on dormancy period and expected germination times. It is expected that most of the planting will occur during late fall or early spring periods. Vegetation characteristics for each area will be designed to allow the highest species diversity and greatest vegetation survival rates. Selected species will be dependent on availability of transplants. The floristic composition of the existing wetland areas was analyzed to aid in creating the list of species to 9 • r i s • i be planted. All selected species will be native to North Carolina and will be obtained from local nurseries if possible. A vegetation list of species that may be utilized is included in Appendix 4. 6 iyliti~ation `Vork Plan. • All work will be done utilizing current Best Management Practices. • All disturbed riparian areas will be replanted 8 to 12 ft on center with bare root or containerized woody trees and shrubs. (Species List in Appendix 4). Adaptive Management Clause: • During construction minor changes to the proposed restoration may be made if more logical or affective means to achieve the projected goals becomes apparent. Construction Schedule • All proposed restoration activities will begin once the final grades have been acquired for the proposed project and adjacent slopes have been stabilized. The restoration activities will be complete prior to the completion of the construction of the proposed project. 7. Monitoring and Success Criteria • 6 monitoring reports over 5 years (a 6-month and 5 annual) will be submitted to the USACE for review. Monitoring reports will include: o Photographs taken from established photo locations that will depict all of the restoration sites. 0 4 Permanent cross sections will be established along the enhanced tributaries. Cross sections will be overlaid with previous reports to determine if the streams dimension is changing. o Survival rates of planted woody vegetation in both riparian and wetland areas will be analyzed utilizing a stem count. o Hydrology success will be monitored utilizing peizometers. Success Criteria: o Vegetation success on both stream buffer areas and within the created wetland areas, will be qualified by 75% survival. o Hydrology success within the created wetland areas will be achieved by having soils saturation within 14 inches of the surface for 3 consecutive weeks during the growing season. Hydrology will be regularly monitored for level of saturation, using established piezometers. • Contingency Plan: If changes to the streams dimension, pattern or profile are deemed to be negative, leading toward instability, changes to the stream may be made. 10 o Changes may include: • Placement of in-stream structures to stabilize the stream. • Modifying the streams dimension to establish a more appropriate stream dimension. • Stabilizing the stream banks with additional coir matting and vegetation. If the created wetland fails to meet hydrologic standards; the elevations within the created wetland may be adjusted or adjustments may be made to redirect surface flows through the created wetland areas. If the wetlands fail to meet vegetation success the areas will be replanted with different species or hardier stock. Party Responsible for Mitigation Activities: Wal-Mart Real Estate Business Trust.

It is expected that most of the planting will occur during early spring or late fall periods. Vegetation characteristics for the area will be designed to allow the highest species diversity and greatest vegetation survival rates. Selected species will be dependent on availability of transplants. All selected species will be native to North Carolina and will be obtained from local nurseries if possible. The following list includes a selection of species that may be used for the restoration project. Figure 6 of Appendix 4 QF W ATF9 Michael F. Easley, Governor Q ~ William G.

Waste Treatment Facilities Stormwater • The project will utilize awetlands-type retention basin and will be designed in strict accordance with the requirements of Buncombe County and NC DENR. Attached is a memo from Freeland and Kauffinan, Inc. summarizing the Storm Water Management Design. Wastewater • The site will tie into existing sewer lines, so all wastewater will be treated by the Metropolitan Sewerage District of Buncombe County, NC. Mitigation Plan An onsite mitigation meeting took place October 11, 2006 with NCDENR, USACE, FWS, and NCWRC. Based on discussions regarding the proposed mitigation plan, we revised the plan to eliminate the priority 2 stream restoration in favor of stream enhancement and spot stabilization, due to the lack of buffer available. We have revised the wetland mitigation by eliminating the onsite wetland creation in favor of utilizing the Ecosystem Enhancement Program (EEP). A complete revised on-site mitigation plan is included for your review. Monitoring reports will be submitted to both the USACOE and NC DWQ for review. Avoidance and Minimization Included in Appendix Aare five site layouts. The first layout is the original site plan submitted in the permit application, dated May 8, 2006. The second layout is the P0, Box 3744 Green`ille, South Carolina 29608 (864) 271-3040 Fax (864) 23~-9299 /~ 1~ /~ 1~ '! first alternative explored, previously referred to as Alternative 1. This layout was ,~ originally submitted August 11, 2007. The third layout is the second layout that was explored, previously referred to as Alternative 2. This layout was originally submitted 1~ October 24, 2006. The fourth layout is the one requested in your letter dated January 16, ~~ 2007, in which the store is relocated and reoriented to the NE. Finally, the fifth layout is „ of the current proposed site plan. Each layout is addressed below individually: Layout 1-Original Site Plan: The original site plan submitted involved impacting 1.93 acres of Waters of the US for commercial development. The plan called for approximately 110,000 to 120,000 c.y. of imported clean fill material, due to the significant difference in elevation between Airport Road and the site. The site plan included a retaining wall along the northern portion of the proposed development in order to avoid impacts to "Stream 1 ". Layout 2 -Alternative 1: In the first alternative layout, the use of two retaining walls did allow for an overall reduction of wetland impacts by a total of 0.37 acres, however, due to the relocation of the stormwater detention basin, the alternate site layout also impacts 742 linear feet of stream. The stormwater management needs to be located at a lower elevation than the developed area. Therefore, the logical locations for the ponds are at the lowest points on the property. If the area behind the western retaining wall was utilized for a detention pond, it would still be necessary for a second pond in order to meet the detention requirements for the site. Storm drain would have to be punched through the retaining wall and be routed to the proposed pond. In order to install the storm drain, a fair amount of wetlands would still have to be impacted. Thus impacts would exist on the stream as well as the western wetland area "D". The configuration of the ponds on the alternative layout shows the least amount of impact possible. Due to the required grading, the retaining wall near the western property boundary would incur a significant increase in cost when compared to the northern retaining wall. The overall cost of both retaining walls for the alternate site layout is approximately $1.8 million dollars, while the cost of the northern retaining wall by itself is $260,000. From a strictly economic standpoint, the $1.5 million (592% increase in cost) is not viable for the scope of the project and represents a dramatic increase in overall cost. Layout 3 -Alternative 2: This alternative involves rotating the building so that the side is oriented toward Airport Road and utilizing the out lots as satellite parking with a span over Wetland "E". As you can see from the site plan, the re-orientation of the building and the spanning of Wetland "E" does not allow for adequate parking or access to the front of the building. Commercial centers are required by law to provide a certain number of handicapped parking spaces with easy access to the front of the store for patrons with disabilities. In addition, extensive retaining walls would be necessary, along with the span for Wetland Area "E". This layout would not be feasible due to the lack of adequate parking, lack of adequate access to the front of the store and additional costs associated with abridge/span and the multiple retaining walls needed to avoid impact to "Wetland Area E". Based on the initial lack of feasibility, this alternative was not pursued further with regards to preliminary engineering plans, stormwater plans, grading, etc. Layout 4 -Alternative 3: The third alternative layout looks at rotating the building and relocating it towards the northeast corner of the property. With this site plan, the northern entrance drive is significantly shorter, thereby .necessitating that the overall finished elevation of the development be higher in order to keep the drive at an allowable slope. In the proposed site plan, the drive drops down at a 6% slope over a much longer distance. With this site plan, the slope would increase to 8% and the finished elevation would rise by 20 feet. By increasing the finished elevation by 20 feet, the overall amount of imported fill material required jumps from approximately 110,000 - 120,000 c.y. to somewhere on the order of 400,000 to 500,000 c.y. By using the conservative estimate of $7.50/c.y. provided by the engineer and using the difference between the estimated 120,000 c.y of fill required for the proposed project and the estimated 400,000 c.y. of fill required for this layout, the cost difference would be a minimum of $2.1 million dollars. Clearly, this would be cost- prohibitive for this project. In addition to the added cost of fill material, the cost of the retaining walls would increase dramatically, as they would now be significantly higher. The retaining wall separating the development from Stream 1 would now be approximately 45 feet tall along the rear of the store, at least twice as tall as what was originally proposed. As with Alternative 1, the cost of the retaining walls makes the project non-viable. Furthermore, because the overall elevation must be raised in this plan, the fill slopes become much larger along the back of the project. The height of the fill slopes requires that it be graded out at a 3:1 ratio, rather than transitioning to a 2:1 ratio as in the proposed site layout. This results in greater overall impact, specifically with the largest wetland, Wetland C. In this layout, the outlots have remained as it was not possible, due to the shape of the property, to place the store any closer to the corner of the property without impacting the stream. Also, please note that Wal-Mart does not allow parking past the mid-point of their building when it would be isolated from the main parking field, across major access and service drives, or when it will be hiddden from view by the building due to safety considerations. Therefore, it would not be possible to use the outlots as additional parking in order to reduce the amount of parking elsewhere. Layout 5 -Revised Site Plan: The revised site plan reduces the overall impervious surface to approximately 16.7 acres. By pulling back along the northern portion of the proposed development, the new site plan stays off of stream to avoid impact without the use of a retaining wall. Eliminating the need for the original retaining wall without increasing impact, the developer was able to shift the wall to the back of the development and further reduce impacts to the largest wetland onsite, Wetland C. The result is a reduction of 0.14 acre of impact. Under the revised site plan, the total proposed impacts to Waters of the US equals 1.78 acres. Additionally, please note that the outlots do not require stream impacts. All in all, the applicant has avoided and minimized impacts to Waters of the US to the maximum extent practicable. Alternatives were considered thoroughly prior to submitting the present design and relying on compensatory mitigation. I hope that this addresses all your comments and concerns regarding this project and we can proceed in a timely fashion. If you have any questions, please call me at (864) 271-3040.

P.O. Box 3744 Greenville, South Carolina 29608 Dear Ms. Belanger: Subject: Revised Mitigation Plan, Wal-Mart Retail Store Located on Airport Road, South of Asheville, in Buncombe County, North Carolina This is the report of the U.S. Fish and Wildlife Service and the Department of the Interior on the revised compensatory mitigation plan submitted by Wal-Mart Real Estate Business Trust, which you represent, to construct a Wal-Mart retail shopping center and consequent infrastructure. On August 2, 2006, we provided comments to the U.S. Army Corps of Engineers (Corps) regarding the individual application that was submitted for this project, and on October 11, 2006, Mr. Bryan Tompkins of our staff met with you at the site to discuss the project plans, proposed impacts, and the compensatory mitigation plan proposed by the applicant. Information for this report is based on a review of the revised compensatory mitigation plan which we received via fax on January 24, 2007. This report is submitted in accordance with the provisions of the Fish and Wildlife Coordination Act, as amended (16 U.S.C. 661-667e). Mitigation Overview -The proposed mitigation plan is being submitted by the Wal-Mart Real Estate Business Trust to provide mitigation for the proposed impacts associated with the construction of the Airport Road Retail Center. Mitigation is proposed for impacts to 1.59 acres of wetlands and 5041inear feet (lf) of stream channel. The original mitigation plan proposed a combination of stream relocation establishment and Priority 2 stream enhancement activities for impacts to on-site stream channels, and two wetland creation areas were proposed as mitigation for impacts to on-site wetlands. The proposed stream relocation consists of redirecting a portion of the on-site stream into an existing ephemeral channel and enhancing about 1601f of the ephemeral channel to accommodate the new flow. Priority 2 stream enhancement is proposed for about 4101f of the remaining stream channel. During the site visit, we expressed our concerns regarding the creation of wetlands; we generally do not recommend wetland creation for mitigation because a successful wetland creation cannot be guaranteed. Revised Mitigation Plan - We agree with the proposal to relocate and reestablish the existing stream into the existing ephemeral channel, and we agree with the Priority 2 stream enhancement. The stream channel has experienced some down-cutting and bank erosion in the past, possibly during the on-site logging activities and watershed development. It currently appears to be stabilizing. During the site visit, we noticed a large amount of debris in the stream, but we did not notice any active stream-bank erosion. The pattern and profile of the stream appear to be stable; therefore, we believe that replanting/reestablishing the riparian vegetation and removing the debris from the stream channel will greatly improve its quality. However, from the total impacts to the stream channels, we agreed that 504 if of mitigation credits will be needed to compensate for the impacts of the project to on-site stream channels. If we subtract the 1601f of mitigation (for relocating and restoring 160 if of existing ephemeral stream channel) from the tota15041f of impacts, 344 if of mitigation credits is needed to compensate for the remaining impacts. If Priority 2 stream enhancement is used as mitigation for the remaining 3401f of impacts, a mitigation activity multiplier of 1.5 to 2.5 is used to determine the amount of mitigation credits needed.' If we use the lowest mitigation activity multiplier of 1.5, then 5161f (1.5 multiplied by 344 lf) of Priority 2 stream enhancement is needed to mitigate for the remaining 344 if of stream channel impacts. Your client is proposing 4101f of Priority 2 stream enhancement activities, which results in a discrepancy of 106 if of stream channel mitigation credits. We recommend that the mitigation plan be revised (e.g., increase payment to the NCEEP) to provide compensation for the remaining 106 if of stream channel mitigation credits needed. The revised mitigation plan states that the wetland creation mitigation proposal for project impacts to wetlands has been eliminated and that a payment to the NCEEP will be made to compensate for the impacts. We commend your client for removing the wetland creation from the mitigation proposal. We recommend that the payment to the NCEEP be calculated using a 2:1 ratio. Therefore, we believe about 3.2 acres of wetland mitigation credits should be purchased from the NCEEP to adequately compensate for the wetland impacts of the project. We appreciate the opportunity to provide these comments. If we can be of assistance or if you have any questions, please do not hesitate to contact Mr. Tompkins at 828/258-3939, Ext. 240. In any future correspondence concerning this project, please reference our Log Number 4-2-06-294. Sincerely, rian P. Cole Field Supervisor ' According to the "Stream Mitigation Guidelines" established by the Corps, a mitigation activity multiplier is "applied to each mitigation type to recognize, that for a given reach, the functional improvement associated with mitigation projects increase along the continuum from preservation to enhancement to restoration." The guideline states that for Priority 2 stream enhancement activities, a mitigation activity multiplier of 1.5 to 2.5. This means that for every 100 if of mitigation needed, 150 if to 2501f of mitigation work is required. 2 CC: Mr. David McHenry, Mountain Region Reviewer, North Carolina Wildlife Resources Commission, 20830 Great Smoky Mtn.

The purpose of the site visit was to examine the presence and quality of wetlands and streams on the property, to discuss stream and wetland mitigation and' on-site stormwater management as well as alternative site plans for the property. Present were Dave McHenry with the NC Wildlife Resources Commission as well as Richard Bates and Laura Belanger with Environmental Permitting Consultants, Inc. The following issues are listed that need to be addressed in order for us to complete action on the required 401 Water Quality Certification for this project. Until we receive answers for the following issues, this project will remain on hold as incomplete in accordance with 15A NCAC 2H .0506. 1. Alternate Site Plan -Please see the attached sketch entitled "DWQ Alternative Design, March 5, 2007". The Division believes that this plan (or a slight alteration thereof} is a practical site plan that minimizes impacts to the large central wetland on the property while allowing construction of the Wa1:lrlart, parking equivelant to the proposed plan, an outparcel and possible commercial development of the. southwest corner of the property. We are aware that development of the southwest corner of the' site may require impact of the smaller wetlanddstream ili that area and are willing to discuss possible site plans in that regard. One concern raised by your consultants with regard to this site plan is that Wal-Mart reportedly has a policy to prevent parking on the side of your stores more than one-half the length of the building. However, we believe that this policy must be flexible since the new Wal-Mart at RiverBend Shopping Center in Asheville has pazking at least three-c}uarters down the side of the building. The amount of parking shown on our alternative plan is about the same amount shown on the applicant preferred plan but we aze not able to measure it precisely. If additional parking is needed on the site, it may be possible to widen the connection between the larger parking lot and the one shown on the side of the building in order to have more spaces. If some, small additional wetland fill is needed far this pazking, we are willing to discuss this issue with your consultants. • • ~~~a North Carolina Division of Water Quality 2090 U.S. Highway 74 Swannanoa, tiC 28778 Phone (828) 296.4500 Customer Service Internet www.ntrrale~qua6ly.otg FAX (828) 299-7043 I-877.623748 An Equal OpportunilylAffimtative Allan Empbyer-5096 Retydedfl OYe Post Consumer Paper • • • • • • • • • •. • • • • • • Airport Road Retail Shopping Center Unnamed tributary to French Broad River DWQ # 06-0922 version 2 Buncombe County Page 2. Another concern raised by your consultants is the grading that would be needed on the site and concerns about balancing cut and fill on the site. Division staff believe that the proposed plan would minimize the need for extensive site grading and note that the site presently is at the level of Airport Road. Therefore location of the building and parking lot closer to Airport Road should require less cut and fill overall. In summary, we believe that this alternative site plan is practical and would clearly reduce the amount of wetland fill on the site to less than one acre. If wetland fill is less than one acre, then the Division will not require compensatory wetland mitigation but we understand that the US Army Corps of Engineers will still require mitigation for the reduced impacts to the wetlands on the site (see item three below). 2. Stormwater management -The present plan for stormwater management is to construct a "wetlands- type retention basin" according to the August 9, 2006 letter from your engineers {Freeland and Kaufmann, Inc. - Mr. Michael Ranks). According to the description in this memo, you are basically planning to construct wet detention ponds with littoral shelves as required by DWQ's Stormwater Design Manual. . 3. Compensatory mitigation a. Stream mitigation -The present plan to restore the hydrology of the channel that flows along the northern property boundary is acceptable to the Division. We suggest that a fence be constructed along the property line to help control trash dumping into the stream. In addition, please be sure that DWQ and the US Army Corps of Engineers are copied on the mitigation plan and annual reports. b. Wetland mitigation - As noted above, impacts to wetlands would be much less than one acre with the proposed alternative site plan. Therefore if this plan is implemented, DWQ will not require compensatory wetland mitigation. However we understand that the US Army Corps of Engineers will still require compensatory wetland mitigation. V4~e believe that it may be possible to provide on-site enhancement of the large, central wetland by directing treated stormwater to flow at non-erosive velocities into the wetland. From our field visit, the upper end of the wetland appears to be somewhat drier than expected. We believe that rewetting this area with the treated stormwater will enhance the hydrology and water quality function of the wetland and then may serve as adequate compensatory mitigation for the reduced impact. If the Corps is able to accept this approach as mitigation, then a payment of about $88,553 to the NC Ecosystem Enhancement Program for mitigation would not be needed. We have had initial discussions with Tom Walker of the US Army Corps of Engineers concerning this approach and if you would like to pursue this approach to mitigation, please have your consultants contact him directly. If we can assist in this discussion, please let us know as well. Airport Road Retail Shopping Center Unnamed tributazy to French Broad River DWQ # 06-0922 version 2 Buncombe County Page 3 _ In summary, we believe that a revised site plan (as outlined above and shown on the attached sketch plan} would greatly reduce impacts to the lazge, central wetland on the site. In addition, direction of treated stormwater to the remaining wetland will both serve to keep the wetland wet and gossibly serve as compensatory mitigation through enhancing the hydrology and water quality value of the wetland. In order for DWQ to complete our review of the 401 Water Quality Certification for this project, please give provide a thorough analysis of this approach to the Division within two weeks of receipt of this letter.
