Version 3 Project Description 3a Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application The Project site is currently undeveloped but has been contemplated for development since the late 1980's Portions of the site have been graded and virtually all mature vegetation has been removed In 1988, a large amount of fill material was placed on the site bringing the site to it's current elevation An approximate 13 acre portion of the 3 18 acre project site occupies a relic sediment basin located within its center This depression currently contains two wetland units (W 1 W 2) and a portion of an intermittent stream (UT New River), a tributary which onginates along the southern property boundary, as discharge from a sediment pond at the lower extent of an inactive landfill UT New River flows for approximately 450 feet before flowing into a riser in the old sediment basin From this riser, UT New River is piped to the north and under US Hwy 421 (approx 700 feet) and eventually flows into the South Fork of the New River Several stormwater pipes exist on the site that convey off site stormwater to the user A paved drive runs around the perimeter of the relic basin and is approximately 12 feet wide A large portion of the project s to along its northern side has been cleared of vegetation and graded for future development The project site is located adjacent and downslope of the inactive Watauga County landfill Two environmental monitoring wells are located on the project site which allow for testing of a contaminated plume of groundwater from the landfill site These wells are required as part of the landfill closure plan Portions of the solid waste facility are still active including a refuse and recycling center The project site is also adjacent to a Nissan dealership which is located west of an unnamed paved access road to the landfill area This unnamed road forms the western site boundary US Hwy 421 forms the northern property boundary The eastern and southern site boundary abuts the inactive portion of the landfill (east) and Landfill Road with active Watauga County waste collection facilities (south) 3b List the total estimated acreage of all existing wetlands on the property 0 46 acres 3c List the total estimated linear feet of all existing streams (intermittent and perennial)

Justification and Mitigation 1 Avoidance and Minimization 1a Specifically describe measures taken to avoid or minimize the proposed impacts in designing project The Nissan dealership is renting its current location from Mack Brown Chevrolet The Nissan Corporation is requiring the current owner (Applicant) to upgrade the dealership to meet Nissan standards this requirement was part of the original franchise agreement The Applicant has determined that constructing a new dealership is the only alternative because the current landlord will not facilitate the necessary site improvements and there are no other suitable existing dealerships for sale in the Town of Boone The Applicant has searched for three years, with no success, for a parcel in the Town of Boone that meets the site requirements of 1) Uproximately 3 acres of flat or potentially flat land 2) road frontage and high visibility along a mayor transportation corridor, and 3) good access for verge car carriers (trucks with very low ground clearance) The property on which the Applicant is planning to build the new Nissan dealership is being sub divided into three lots With the remaining two lots being retained by the owner for possible future development It is not possible to move the location of the dealership to either of the other lots to avoid the impacts for the following reasons Of the two remaining lots one is set back from the road has no frontage and poor visibility, both lots are much too steep for a car dealership in their existing condition Both lots could be graded off to make them more level but the only practicable place to put the dirt is in the big depression where the old sediment basin is located and where all current impacts are posed To grade either of the two remaining lots and remove the excess dirt off site, would not be economically feasible due to the massive quantity of material involved The current site layout provides the area and access points needed to provide suitable access to and from the dealership The wetlands and stream which will be impacted are of low ecological value The jurisdictional features are located within an old sediment basin which is no longer in use The stream has been classified as intermittent unimportant and is currently piped through much of the site providing little to no habitat for aquatic organisms The remainder of the channel which is open is down cutting through hrough the material which was deposited in the old sediment basin The portion of the channel which is located above the old sediment basin will not be impacted and will be protected through the implementation of a twenty five foot buffer The proposed stormwater devices will treat the surface runoff from the project msunng that downstream water quality is not compromised The site on which the applicant is proposing to build is perfectly situated for commercial business There is an existing intersection adjacent to project site This intersection is already_ controlled by stoplights and will provide access to the dealerslup off of US Highway 421, a mayor Page 8 of 13 PCN Form — Version 1 3 December 10 2008 Version thoroughfare through of the town of Boone 1 b Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques The construction phase of this project will involve excavation, filling and piping of waters of the US Potential impacts associated with this activity include 1) sedimentation of downstream waters during construction, 2) sedimentation of downstream waters following construction due to Inadequate design or construction techniques, 3) degradation of downstream waters from excessive or untreated stormwater runoff from the proposed development 4) thermal Impacts to downstream waters, and 5) degradation of downstream waters from landfill related contamination Initial site grading activities will Include excavation and removal of unsuitable soils and installation of the By Pass Pipe that will convey off -site stormwater and flows from UT -New River through the site _A geotechnical evaluation of on site soils in set to commence In early January 2012 to determine the extent of unsuitable soils and will test soils for contaminants related to landfill leachate This phase of construction will require a specific sequence to ensure all elements will be performed In the dry The following measures, at a minimum will be performed to avoid and minimize impacts during this phase of construction 1) All flow to existing riser in old sediment pond will be dammed using non erosive measures, and pumped to DOT pipe under Hwy 421 2) the existing riser structure will be reconstructed for use as a temporary sediment pond existing accumulated sediment will be excavated to create required volume 3) Temporary dams will be removed allowing flows to repaired riser basin 4) Proposed By -Pass Pipe will be installed in the dry, a pump a -round will again be used to make final connection to UT -New River 5) During excavation and filling of wetlands drainage from wetland W 1 will be routed through a series of filter dams before enterinq sediment pond to allow for maximum sediment removal, polyacrylamides will be used to enhance sediment removal 6) All subsurface drainage will be french drained to By Pass Pipe system 7) Once all off -site water has been captured in the By Pass Pipe system new sediment basins will be constructed in appropriate locations for planned site grading activities these will be detailed on the Erosion Control Plan - A bioretention basin is proposed to treat all stormwater generated on the site The bioretention basin has been designed as a grassed cell with 2 feet of soil media and an underdrain system This configuration was selected due to the contaminated nature of the subsoil and groundwater below this site The goal was to minimize the depth of excavation and to create a system that could treat and discharge the site runoff without it mingling with the potentially contaminated ground water 2 Compensatory Mitigation for Impacts to Waters of the U S or Waters of the State 2a

seasonally (e g typically 3 months) 3 Supporting documentation is presented in Section 111 F SECTION III CWA ANALYSIS A TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs If the aquatic resource is a TNW complete Section III A 1 and Section III D ] only if the aquatic resource is a wetland adjacent to a TNW complete Sections III A 1 and 2 and Section III D 1 otherwise see Section III B below ' 1 TNW Identify TNW Summarize rationale supporting determination 2 Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is adjacent B CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY) This section summarizes information regarding characteristics of the tributary and its adjacent wetlands if any and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met The agencies will assert jurisdiction over non navigable tributaries of TNWs where the tributaries are relatively permanent waters (RPWs) i e tributaries that typically flow year round or have continuous flow at least seasonally (e g typically 3 months) A wetland that directly abuts an RPW is also jurisdictional if the aquatic resource is not a TNW but has year round (perennial) flow skip to Section III D 2 If the aquatic resource is a wetland directly abutting a tributary with perennial flow skip to Section III D 4 ' A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water even though a significant nexus finding is not required as a matter of law if the waterbody4 is not an RPW or a wetland directly abutting an RPW a JD will require additional data to determine if the waterbody has a significant nexus with a TNW If the tributary has adjacent wetlands the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands This significant nexus evaluation that combines for analytical purposes the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary or its adjacent wetlands or both if the JD covers a tributary with adjacent wetlands complete Section III B 1 for the tributary Section III B 2 for any onsite wetlands and Section III B 3 for all wetlands adjacent to that tributary both onsite and offsite The determination whether a significant nexus exists is determined in Section IiI C below 1

(YIN) Size (in acres) N 034 Y 0 12 ' Summarize overall biological chemical and physical functions being performed C SIGNIFICANT NEXUS DETERMINATION ■ A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical physical and biological integrity ' of a TNW For each of the following situations a significant nexus exists if the tributary in combination with all of its adjacent wetlands has more than a speculative or insubstantial effect on the chemical physical and/or biological integrity of a TNW Considerations when evaluating significant nexus include but are not limited to the volume duration and frequency of the flow of water in the tributary and its proximity to a TNW and the functions performed by the tributary and all its adjacent ' wetlands It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e g between a tributary and its adjacent wetland or between a tributary and the TNW) Similarly the fact an adjacent wetland lies within or outside of a floodplam is not solely determinative of significant nexus ' Draw connections between the features documented and the effects on the TNW as identified in the Rapanos Guidance and discussed in the Instructional Guidebook Factors to consider include for example • Does the tributary in combination with its adjacent wetlands (if any) have the capacity to carry pollutants or flood waters to TNWs or to reduce the amount of pollutants or flood waters reaching a TNW9 ' • Does the tributary in combination with its adjacent wetlands (if any) provide habitat and lifecycle support functions for fish and other species such as feeding nesting spawning or rearing young for species that are present in the TNW9 • Does the tributary in combination with its adjacent wetlands (if any) have the capacity to transfer nutrients and organic carbon that support downstream foodwebs9 ' • Does the tributary in combination with its adjacent wetlands (if any) have other relationships to the physical chemical or biological integrity of the TNW9 Note the above list of considerations is not inclusive and other functions observed or known to occur should be documented ' below 1 Significant nexus findings for

University Nissan Site Stormwater Management Plan January 9 2012 Regulatory Requirements The University Nissan Site project will involve grading and filling of portions of an approximate 318 acre site located adjacent to US Hwy 421 and Landfill Road dust east of Boone NC The project will involve impacts to jurisdictional stream and wetland areas and will require both Clean Water Act Section 404 and 401 permits As a condition of the 401 Water Quality Certification (#3821) required from the NC DWQ a Stormwater Management Plan (SMP) is required for the project site An evaluation of the proposed site plan indicates that the site will be defined as High Density and a SMP must be prepared that includes BMP's designed in accordance with the NC DWQ BMP Manual to provide at least 85% removal of TSS 30% total phosphorous 30% total nitrogen and minimize thermal pollution in receiving waters SWM Plan Outline The project site is located at 193 Landfill Road Boone NC access is from both Hwy 421 and Landfill Road The site slopes down from Hwy 421 in the north to a low area in the center and slopes back up towards the Watauga County Landfill to the south The low area in the center of the site contains an old sediment basin and all the jurisdictional streams and wetlands to be impacted All of the proposed impervious surfaces would be located in the northern 3/4 of the site and will drain to the stormwater management measures in the southern portion of the site Based on the proposed site conditions the most suitable BMP that will meet regulatory requirements has been determined to be a bioretention basin The proposed SWM plan involves directing all site runoff to a single bioretention cell Runoff in excess of the calculated water quality volume will overflow a weir into a detention basin All off -site drainage will by -pass the site and will not mingle with any untreated stormwater from the site See Plans and Supporting Calculations for Bioretention Bioretention Cells The proposed bioretention cell has been designed to receive site runoff at a single location via a pipe discharge in to an approximate 1000 sq ft forebay Due to the shallow high water table and the presence of contaminated ground water the bioretention cell has been designed to be as shallow as practicable and still meet regulatory requirements The bioretention cell will be planted grass only over 2 -feet of sod media Sod media specifications are listed in the following section The 1 0 n 1 1 1 n 1/9/2012 bioretention cell will discharge through an underdrain system that will discharge directly to the by -pass pipe carrying off -site drainage to the DOT right -of way Sod Media The sod media for the bioretention cells will be obtained from a local supplier and shall meet the following specifications (adapted from Charlotte Mecklenburg Stormwater BMP Manual) Bioretention Sod Mixture Bioretention soil mix should be developed by amending the existing soil or removing the existing soil and replacing it with the new planting mix The material must be uniform in composition throughout be free of stones lumps live plants and their roots weed seeds sticks and other extraneous material The bioretention sod mixture must meet the followina criteria PARAMETER ACCEPTABLE TESTING TEST METHODS VALUES REQUIRED' Sand Content (ASTM C 144 85 to 88% No recommended Organic

test for soil mixture composition A composite soil test is required to be performed on the soil planting media after it has been mixed and prior to its installation into the bioretention area to determine that the soil constituents meet the acceptable values in the table Drainage Easement A preliminary drainage easement is shown in the Stormwater Management Plans the final easement boundary cannot be surveyed and recorded until after the site is filled The easement will cover the entire site and a small area off -site connecting the northern driveway entrance to the DOT right of -way along Hwy 421 The drainage easement will be recorded and submitted to DWQ prior to commencement of budding construction Maintenance Maintenance watering will be performed immediately after initial construction and installation of plant material for a period of 6 -weeks more or less Thereafter regular inspections maintenance will be performed in accordance with the O &M agreement Construction Sequence The following items will be incorporated into the site Sediment and Erosion Control Plan and communicated to the owner and contractor at preconstruction 1 Bioretention cell location may be used as temporary sediment basins during initial site grading 2 Construction of the bioretention cell shall not commence until all contributing drainage area is permanently stabilized and any sediment accumulated in excavated cell trenches has been removed Cell trenches should be surrounded by straw bales or similar during cell construction to prevent any sediment entering Pretreatment areas shall be stabilized prior to installing underdrain system 3 Sod media mix must be tested and determined to be in accordance with specifications by engineer prior to commencement of cell construction 4 Excavate bioretention cell and line with non -woven filter cloth install washed gravel and underdrain system 5 Cover underdrain system with non -woven filter cloth Cut holes for clean out pipes and seal filter cloth around vertical pipes 6 No equipment shall be permitted over cells after underdrain system is installed 7 Install washed sand layer 8 Install sod media wet down sod media prior to planting to allow for compaction and settlement allow soil media to overlap pretreatment area Bring pretreatment area to final grade and install final sod and gravel filters Use University Nissan 3 of
