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) on the property
The project site contains 245 linear feet There are 450 linear feet on the entire12 54 acre tract
3d
Explain the purpose of the proposed project
The project purpose is to construct a Nissan automobile dealership
3e
Describe the overall project in detail including the type of equipment to be used
The project site is proposed to be developed for the future home of Umversrty Nissan car dealership
As part of site preparations, the relic sediment basin wetlands and 245 linear feet of UT New River
are proposed to be filled or piped in order create a level site Typical equipment will be used as part of
site development trackhoe backhoe bulldozer, and dumptruck

D Impact 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

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

The developed portion of the project site is about 2 5 acres all stormwater runoff from this area will be conveyed to a
bioretention basin with a forebay for primary settling and pretreatment The bioretention basin has been designed as a
grassed cell with 2 feet of sod 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
With this shallow design a minimum separation of almost 3 feet between the bottom of the bioretention cell and the
seasonal high ground water level will be maintained More detail is contained in the attached Stormwater Management

and will be protected by a buffer Also any future development on the two parcels will have to comply with state
stormwater rules in force at the time of development because they were created as part of a subdivision that involved
impacts to Waters of the US requiring a 401 WQC

' Boxes checked below shall be supported by completing the appropriate sections in Section III below
' 2 For purposes of this form an RPW is defined as a tributary that is not a TN W and that typically flows year round or has continuous flow at least 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

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 non RPW that has no adjacent wetlands and flows directly or indirectly into TNWs Explain
findings of presence or absence of significant nexus below based on the tributary itself then go to Section III D
2 Significant nexus findings for non RPW and its adjacent wetlands where the non RPW flows directly or indirectly into
TNWs Explain findings of presence or absence of significant nexus below based on the tributary in combination with all of its
adjacent wetlands then go to Section 111 D
3 Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW Explain findings of
presence or absence of significant nexus below based on the tributary in combination with all of its adjacent wetlands then go to

Instructions for completion of worksheet (located on page 2) Begin by determining the most appropriate ecoregion based on
location terrain vegetation, stream classification etc Every characteristic must be scored using the same ecoregion Assign points
to each characteristic within the range shown for the ecoregion Page 3 provides a brief description of how to review the
characteristics identified to the worksheet Scores should reflect an overall assessment of the stream reach under evaluation If a
characteristic cannot be evaluated due to site or weather conditions, enter 0 in the scoring box and provide an explanation in the
comment section Where there are obvious changes in the character of a stream under review (e g the stream flows from a pasture
into a forest) the stream may be divided into smaller reaches that display more continuity and a separate form used to evaluate each
reach The total score assigned to a stream reach must range between 0 and 100 with a score of 100 representing a stream of the
highest quality

Stormwater Management Plan
University Nissan Projec
January 2012
� ENV
Environmental Consulting Services Inc.
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

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

' * Even though testing is not required for all parameters the inspector reserves the right
to test suspect material and disapprove It for use if results show that parameters do not
meet the acceptable values
1 University Nissan 2 of 4 SWM Narrative
1/9/2012
All bioretention areas must have a minimum of one 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

Bioretention Operation and Maintenance Agreement
I will keep a maintenance record on this BMP This maintenance record will be kept in a
log in a known set location Any deficient BMP elements noted in the inspection will be
' corrected repaired or replaced immediately These deficiencies can affect the integrity
of structures safety of the public and the removal efficiency of the BMP
Important operahon and maintenance procedures
- Immediately after the bioretention cell is established the plants will be watered
twice weekly if needed until the plants become ectabh.shed (commonly six
weeks)
- Snow mulch or any other material will NEVER be piled on the surface of the
bioretention cell
- Heavy equipment will NEVER be driven over the bioretention cell
- Special care will be taken to prevent sediment from entering the bioretention cell
- Once a year a soil test of the soil media will be conducted
After the bioretention cell is established I will inspect it once a month and within 24
hours after every storm event greater than 10 inches (or 15 inches if in a Coastal
County) Records of operation and maintenance will be kept in a known set location
and will be available upon request
