Tax Parcel ID numbers: 201-031-31, 201-031-09, and 201-031-20.
Decimal Degree Coordinate Location of Project Site: N35.135535°, W80.939497°
USGS Quadrangle Name: Charlotte West quadrangle, North Carolina, dated 1996
Current Land Use
The site consists of an undeveloped lot with maintained grass and several large trees. The site is
located in an area of commercial and retail properties. Typical on-site vegetation includes willow oak
(Quercus phellos), boxelder (Acer negundo), sweetgum (Liquidambar styraciflua), green ash
(Fraxinus pennsylvanica), sawtooth blackberry (Rubus argutus), goldenrod (Solidago canadensis), and
fescue (Festuca sp.).
According to the Soil Survey of Mecklenburg County' (Figure 2. NRCS Soil Survey Map, enclosed),
on-site soils consist of Iredell fine sandy loam, 1 to 8 percent slopes (IrB), Monacan soils (MO), and
Wilkes loam, 8 to 15 percent slopes (WkD). Iredell fine sandy loam exhibits slow permeability and a
medium available water capacity. Monacan soils exhibit moderate permeability and a high available
water capacity. Wilkes loam exhibits moderately slow permeability and very low available water
capacity. Iredell fine sandy loam is moderately well drained. Wilkes loam is well drained. Monacan
soils are somewhat poorly drained and are listed in the North Carolina Hydric Soils List for

Jurisdictional Determination
On October 20, 2010, CWS scientists Thomas Blackwell and Gregg Antemann, PWS delineated
jurisdictional waters of the U.S. within the project area. Jurisdictional areas were delineated using the
U.S. Army Corps of Engineers (USACE) Routine On-Site Determination Method. This method is
defined in the 1987 Corps of Engineers Wetlands Delineation Manual , with further technical guidance
from the Eastern Mountains & Piedmont Interim Regional Supplements, dated July 2010. A Wetland
Determination Data Form representative of on-site wetland areas has been enclosed (DPI). A Wetland
Determination Data Form representative of non jurisdictional upland areas has been enclosed (DP2).
Jurisdictional stream channels were classified according to recent USACE and North Carolina
Division of Water Quality (NCDWQ) guidance. These classifications included sampling with a D-
shaped dip net, taking photographs, and defining approximate breakpoints (location at which a channel
changes classification) within each on-site stream channel. NCDWQ Stream Classification Forms and
USACE Stream Quality Assessment Worksheets representative of Stream A are enclosed (SCP1).
The results of the on-site field investigation conducted by CWS indicate that there is one jurisdictional
stream channel (Stream A) and one jurisdictional wetland (Wetland AA) located within the project area
(Figure 3, enclosed). Stream A is an unnamed tributary to Coffey Creek which is located in the Catawba
River basin (HU# 03050103)6 and is rated "Class C Waters" by the NCDWQ. On-Site jurisdictional
waters of the U.S. total approximately 0.027 acres (1,176 square feet). On-Site jurisdictional waters are
summarized in Table 1 below.

Intermittent Streams
Stream A flows north along the western edge of the site for approximately 183 linear feet (Figure 3,
enclosed). Stream A was evaluated to be intermittent and exhibited strong bed and bank, weak flow,
weak sinuosity, substrate consisting of coarse sand, and an average ordinary high water width of 2.5
feet. Biological sampling revealed a moderate presence of pouch snails and isopods. There is

evidence of pollution by oil. This is likely the result of runoff from adjacent parking lots. Due to
evidence of flow for at least three consecutive months in an average year, Stream A was classified as a
Relatively Permanent Water with Seasonal Flow (Seasonal RPW) according to USACE/EPA
guidance. Intermittent Seasonal RPW Stream A scored 40 out of a possible 100 points on the USACE
Stream Quality Assessment Worksheet and 24 out of a possible 63.5 points on the NCDWQ Stream
Classification Form, indicating unimportant intermittent status (SCP 1, enclosed). Photographs A and
B are representative of Unimportant Intermittent Seasonal RPW Stream A.
Wetlands
Wetland AA is a palustrine forested wetland (PFO1B), approximately 0.016 acre in extent, located
directly abutting Intermittent Seasonal RPW Stream A at the northern end of the project area (Figure 3,
enclosed). Wetland AA exhibits low chroma soils (7.5YR 3/1) with common, distinct mottles (7.5YR
4/3), saturation within the upper 12 inches of the soil profile, wetland drainage patterns, and
waterstained leaves. Dominant vegetation in this wetland includes soft rush (Juncus effusus), box
elder (Acer negundo), green ash (Fraxinus pennsylvanica), sugar berry (Celtis laevigata), black willow
(Salix nigra), Virginia creeper (Parthenocissus quinquefolia), and sedge (Carex sp.). A Wetland
Determination Data Form representative of Wetland AA is enclosed as DP1. Photographs C and D are
representative of Wetland AA.
Agency Correspondence
Cultural Resources
A letter was forwarded to the State Historic Preservation Office (SHPO) on November 4, 2010 to
determine the presence of any areas of architectural, historic, or archaeological significance that would
be affected by the project. In a response letter dated November 14, 2010 the SHPO stated, "We have
conducted a review of the project and are aware of no historic resources which would be affected by
the project. Therefore, we have no comment on the project as proposed". A copy of the SHPO
response letter is attached CWS consulted the Charlotte Mecklenburg Historic Landmarks
Commission database and found no listed properties within the project area.
Protected Species
A letter was forwarded to the North Carolina Natural Heritage Program (NCNHP) on November 4,
2010 to determine the presence of any federally-listed, candidate endangered, threatened species or
critical habitat located within the project area. In a response letter dated November 16, 2010 the
NCNHP stated that, "The Natural Heritage Program has no record of rare species, significant natural
communities, significant natural heritage areas, or conservation/managed areas at the site nor within
0.3-mile of the project area". A copy of the NCNHP response letter is attached.
In addition, the NCNHP Geographic Information Systems (GIS) database Virtual Workroom and
Element Occurrence (EO) database was reviewed for a listing of EOs of endangered or threatened
species within or near the project area. The EO database identified no federally endangered or
threatened species within a two-mile radius of the project area.
Purpose and Need for the Project
The purpose of this project is to develop a gas filling station and associated convenience store on the
site. The site is located on the corner of South Tryon Street and Sandy Porter Road and is located
within an area of commercial and retail land use. The proposed development of the site will include
the filling station forecourt, convenience store, necessary parking facilities, and garbage storage
Sandy Porter Road QuikTrip Site January 12, 2011
Nationwide Permit No. 39 Proiect No. 2010-2754
facilities. The project site is in a prime location for the proposed use and is currently in a vacant
condition.
Development of the proposed project will result in impacts to Jurisdictional Waters of the U.S. These
impacts are necessary in order to accommodate the proposed project, including the necessary entrance
and egress locations and car parking facilities while maintaining the necessary buffers and setbacks
required by City of Charlotte zoning ordinances.
Avoidance and Minimization
Impacts to on-site jurisdictional waters of the U.S. have been reduced to the maximum extent practicable.
Proper sediment and erosion control measures will be used to minimize disturbances to downstream
waters. All work will be constructed in the dry in accordance with Water Quality Certification (WQC)
No. 3 821.
Alternative site plans were investigated in an attempt to minimize impacts to jurisdictional waters.
Alternative Site Plan A (Figure 4, attached), which involved relocating garbage dumpsters to reduce
impacts to Stream A, was investigated but found to be impossible due to presence of adjacent residential
property at the northeast corner of the site. The presence of adjacent residential properties means that
local zoning regulations require setbacks that make Alternative Site Plan A unworkable.
The possibility of eliminating some parking spaces was also discussed. This option was also found to be
unacceptable. Several existing QuikTrip locations are in the process of acquiring additional real estate
adjacent to the existing stores to increase available parking. This location is surrounded by existing
development and therefore restricted from future expansion.
Unavoidable impacts to jurisdictional waters of the U.S. will be limited to approximately 183 linear feet
of unimportant intermittent stream channel and approximately 0.016 acre of jurisdictional wetlands.
Proposed Impacts to Jurisdictional Waters
Unavoidable impacts to Jurisdictional Waters of the U.S. total 183 linear feet of unimportant intermittent
stream and 0.016 acre of jurisdictional wetland (Figure 5, attached).
Permanent impacts to Unimportant Intermittent Seasonal RPW Stream A total 183 linear feet, and are the
result extending the existing 48" reinforced concrete pipe (RCP) along the length of rear of the property
(Figure 5 and Plan Sheet C120, attached). This pipe is necessary as the parking lot and trash enclosures
will extend into the existing stream channel. Permanent Impacts to Wetland AA total 0.016 acre, and are
the result of the placement of fill (0.12 acre) necessary to accommodate the access drive and parking
spaces at the rear of the property and the placement of a rip rap apron (0.04 acre) at the outlet of the new
pipe. Unavoidable impacts to on-site jurisdictional waters are summarized in Table 2, below.

On behalf of CSWS, CWS is submitting a Pre-Construction Notification Application with attachments in
accordance with Nationwide Permit General Condition No. 27, (enclosed) and pursuant to Nationwide
Permit No. 39 and WQC No. 3821.
Compensatory Mitigation
Permanent impacts to jurisdictional waters of the U.S. have been limited to 183 linear feet of
unimportant intermittent stream channel and 0.016 acre of wetland impacts. Therefore, no mitigation
is proposed for these impacts. Conversations with Mr. Alan Johnson of the NCDWQ indicated that
due to the poor condition of this stream, and its urban setting, the NCDWQ would not require any
mitigation for impacts associated with this project. Mr. Johnson conducted a site visit in October
2010.
Storm Water Management
The client is working with the Charlotte Mecklenburg Storm Water Services, the delegated storm
water authority for this site, to get approval for a proprietary underground detention system (Crystal
Stream). A copy of the approval letter will be forwarded to NCDWQ as soon as it is received. A
storm drainage plan for the site along with the detail sheets for the Crystal Stream/underground
detention system is attached (Plan Sheets C 120, C 121, and C 123). If the proprietary system is not
approved our client will used a sand filter system to treat storm water from the site. A stormwater
drainage area map for the site is attached. A Sand Filter Design Form, Sand Filter Detention
Worksheet, Sand Filter BMP Calculations, and a completed Stormwater Management Application
Form - Sand Filter Supplement are also attached.

D.' Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Impacts to on-site jurisdictional waters of the U.S. have been reduced to the maximum extent practicable. Proper sediment
and erosion control measures will be used to minimize disturbances to downstream waters. All work will be constructed
in the dry in accordance with Water Quality Certification (WQC) No. 3821.
Alternative site plans were investigated in an attempt to minimize impacts to jurisdictional waters. Alternative Site Plan A
(Figure 4, attached), which involved relocating garbage dumpsters to reduce impacts to Stream A, was investigated but
found to be impossible due to presence of adjacent residential property at the northeast corner of the site. The presence
of adjacent residential properties means that local zoning regulations require setbacks that make Alternative Site Plan A
unworkable.
The possibility of eliminating some parking spaces was also discussed. This option was also found to be unacceptable.
Several existing QuikTrip locations are in the process of acquiring additional real estate adjacent to the existing stores to
increase available parking. This location is surrounded by existing development and therefore restricted from future
expansion.
Unavoidable impacts to jurisdictional waters of the U.S. will be limited to approximately 183 linear feet of unimportant
intermittent stream channel and approximately 0.016 acre of jurisdictional wetlands..
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Impacts to on-site jurisdictional waters of the U.S. have been reduced to the maximum extent practicable. Proper
sediment and erosion control measures will be used to minimize disturbances to downstream waters. All work will be
constructed in the dry in accordance with Water Quality Certification No. 3821.

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 in 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.

Wetlands: 0.016 acres.
c. Limits (boundaries) of jurisdiction based on: 1987 Delineation Manual
Elevation of established OHWM (if known):
2. Non-regulated waters/wetlands (check if applicable):3
Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional.
Explain:
' Boxes checked below shall be supported by completing the appropriate sections in Section III below.
z For purposes of this form, an RPW is defined as a tributary that is not a TNW 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 III.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.1. 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 waterbody° 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. Characteristics of non-TNWs that flow directly or indirectly into TNW
(i) General Area Conditions:
Watershed size: 67.7 square miles
Drainage area: 24 acres
Average annual rainfall: 45 inches
Average annual snowfall: 3 inches
(ii) Physical Characteristics:
(a) Relationship with TNW:

Project waters are 1 (or less) river miles from RPW.
Project waters are 1-2 aerial (straight) miles from TNW.
Project waters are I (or less) aerial (straight) miles from RPW.
Project waters cross or serve as state boundaries. Explain:
Identify flow route to TNW5: Seasonal RPW flows to Perennial RPW, flows Coffey Creek, flows to TNW (Sugar
Creek).
4 Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and
West.
s Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW.

Summarize overall biological, chemical and physical functions being performed: provides amphibian habitat, polution
filtration, and stormwater detention.
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 floodplain 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 TNW?
• 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 TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that
support downstream foodwebs?
• Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or
biological integrity of the TNW?
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 III.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
Section III.D:
D. DETERMINATIONS OF JURISDICTIONAL FINDINGS. THE SUBJECT WATERS/WETLANDS ARE (CHECK ALL
THAT APPLY):
1. TNWs and Adjacent Wetlands. Check all that apply and provide size estimates in review area:
? TNWs: linear feet width (ft), Or, acres.
[] Wetlands adjacent to TNWs: acres.
2. RPWs that flow directly or indirectly into TNWs.
Q Tributaries of TNWs where tributaries typically flow year-round are jurisdictional. Provide data and rationale indicating that
tributary is perennial:
® Tributaries of TNW where tributaries have continuous flow "seasonally" (e.g., typically three months each year) are
jurisdictional. Data supporting this conclusion is provided at Section III.B. Provide rationale indicating that tributary flows
seasonally: Stream A flows north along the western edge of the site for approximately 183 linear feet (Figure 3, enclosed).
Stream A was evaluated to be intermittent and exhibited strong bed and bank, weak flow, weak sinuosity, substrate consisting
of coarse sand, and an average ordinary high water width of 2.5 feet. Biological sampling revealed a moderate presence of
pouch snails and isopods. Due to evidence of flow for at least three consecutive months in an average year, Stream A was
classified as a Relatively Permanent Water with Seasonal Flow (Seasonal RPW) according to USACE/EPA guidance.
Intermittent Seasonal RPW Stream A scored 40 out of a possible 100 points on the USACE Stream Quality Assessment
Worksheet and 24 out of a possible 63.5 points on the NCDWQ Stream Classification Form, indicating unimportant
intermittent status (SCP 1, enclosed). Photographs A and B are representative of Unimportant Intermittent Seasonal RPW
Stream A.

Dear Ms. Singleton:
Dee Freeman, Secretary
The Natural Heritage Program has no record of rare species, significant natural communities, significant
natural heritage areas, or conservation/managed areas at the site nor within 0.3-mile of the project area.
There is a rare plant location - for Carolina birdfoot-trefoil (Acmispon helleri) - about 0.3-mile to the
north, but as the footprint of the project is very small, this rare plant site would not be impacted.
You may wish to check the Natural Heritage Program database website at www.ncnhp.org for a listing of
rare plants and animals and significant natural communities in the county and on the quad map. Our
Program also has a new website that allows users to obtain information on element occurrences and
significant natural heritage areas within two miles of a given location:
<http://nhpweb.enr.state.nc.us/nhis/public/gmap75_main.phtml>. The user name is "public" and the
password is "heritage". You may want to click "Help" for more information.
NC OneMap now provides digital Natural Heritage data online for free. This service provides site
specific information on GIS layers with Natural Heritage Program rare species occurrences and
Significant Natural Heritage Areas. The NC OneMap website provides Element Occurrence (EO) ID
numbers (instead of species name), and the data user is then encouraged to contact the Natural Heritage
Program for detailed information. This service allows the user to quickly and efficiently get site specific
NHP data without visiting the NET workroom or waiting for the Information Request to be answered by
NHP staff. For more information about data formats and access, visit <www.nconemap.com>, then click
on "FTP Data Download", and then "nheo.zip" [to the right of "Natural Heritage Element Occurrences"].
You may also e-mail NC OneMap at <datag(-ncmail.net> for more information.
Please do not hesitate to contact me at 919-715-8697 if you have questions or need further information.

Sand Filter 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 maintenance procedures:
- The drainage area will be carefully managed to reduce the sediment load to the sand filter.
- The sedimentation chamber or forebay will be cleaned out whenever sediment depth exceeds
six inches.
- Once a year, sand media will be skimmed.
- The sand filter media will be replaced whenever it fails to function properly after maintenance.
The sand filter will be inspected quarterly and within 24 hours after every storm event greater than
1.0 inches (or 1.5 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.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired
immediately.
BMP element: Potential problem. How I will remediate the problem:
Entire BMP Trash/ debris is resent. Remove the trash/ debris.

gullies have formed. gully, and then plant a ground cover and
water until it is established. Provide lime
and a one-time fertilizer application.
Vegetation is too short or too long. Maintain vegetation at an appropriate
height.
Flow diversion structure The structure is clogged. Unclog the conveyance and dispose of any
sediment offsite.
The structure is damaged. Make any necessary repairs or replace if
damage is too large for repair.
Forebay or pretreatment area Sediment has accumulated to a Search for the source of the sediment and
depth of greater than six inches. remedy the problem if possible. Remove
the sediment and stabilize or dispose of it
in a location where it will not cause
impacts to streams or the BMP.
Erosion has occurred. Provide additional erosion protection such
as reinforced turf matting or riprap if
needed to prevent future erosion
problems.
Weeds are present. Remove the weeds, preferably by hand. If
a pesticide is used, wipe it on the plants
rather than spraying.
