APPROVAL of 401 Water Quality Certification and ADDITIONAL CONDITIONS
Basil Hooper
PO Box 112
Avon, NC 27915
Dear Mr. Hooper:

You have our approval, in accordance with the attached conditions and those listed below, to place fill material in 0.1 acres
of wetlands or waters for the purpose of residential fill, as you described in your application dated June 2, 1999. After reviewing
your application, we have decided that this fill is covered by General Water Quality Certification Number 3106. This certification
allows you to use Nationwide Permit Number 18 when the Corps of Engineers issues it. In addition, you should get any other
federal, state or local permits before you go ahead with your project including (but not limited to) Sediment and Erosion Control,
Coastal Stormwater, Non-Discharge and Water Supply Water shed regulations. This approval will expire when the
accompanying 404 or CAMA permit expires unless otherwise specified in the General Certification.
This approval is only valid for the purpose and design that you described in your application except as modified below. If
you change your project, you must notify us and you may be required to send us a new application.. If the property is sold, the
new owner must be given a copy of this Certification and approval letter and is thereby responsible for complying with all
conditions. If total wetland fills for this project (now or in the future) exceed one acre, compensatory mitigation may be required
as described in 15A NCAC 2H.0506 (h) (6) and (7). For this approval to be valid, you must follow the conditions listed in the
attached certification and any additional conditions listed below.
1. Deed notifications or similar mechanisms shall be placed on all lots with remaining jurisdictional wetlands and waters or areas
within 50 feet of all streams and ponds to notify the state in order to assure compliance for future wetland and/or water impact.
These mechanisms shall be put in place within 30 days of the date of this letter or the issuance of the 404 Permit (whichever is
later).
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must act
within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition, which conforms to Chapter
150B of the North Carolina General Statutes to the Office of Administrative Hearings, P.O. Box 27447, Raleigh, N.C. 27611-
7447. This certification and its conditions are final and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you have
any questions, please telephone John Domey at 919-733-1786.

I have reviewed the subject stormwater management plan. Some of the
stormwater will be diverted to the wetland/stream per the 401 requirement. Also, the side
slopes are 2:1, but a vegetative shelf has been provided which should address safety
issues. I recommend that the plans be approved.

Dear Mr. Stone:

NCDENR
Division of Water Quality
July 21, 1999
Subject: Market Square
DWQ Project No. 990564
Mecklenburg County
The Wetlands Unit staff reviewed the stormwater management plans for the subject project and determined
that additional information is necessary to complete the technical review process. The required additional
information is as follows:
1. Orifice Outlet Structure
Please provide plan details for the outlet structure. Please note that the design should include an
"emergency" drain that is capable drawing down the permanent pool.
2. Forebay
All stormwater wet detention basins are required to have a forebay to facilitate TSS removal. The
forebay should be approximately 20% of the total basin volume. NCDENR Stormwater Best
Management Practices Manual, November 1995, page 4, item Le. Please revise the engineering
plans to meet this requirement.
3. Vegetated Side Slopes
The basin side slopes above the permanent pool down to the vegetative shelf must be stabilized with
vegetation and side slopes no steeper than 3:1 (horizontal to vertical). Landscape information must
be clearly stated on engineering plans.
4. Vegetative Shelf
A vegetative shelf around the perimeter of the pond is required. The shelf shall be gently sloped (6:1
or flatter) and shall consist of native vegetation. Please specify this on the engineering plans.
5. Sediment Removal
If the basin is proposed to be used as a sediment basin during construction, the plans must clearly
indicate that accumulated sediment will be removed prior to implementation as a wet detention
basin.

6. Operation and Maintenance Agreement
An operation and maintenance agreement is required.
A stormwater control structure will not operate as designed without regular maintenance. Typical
requirements for an operation and maintenance plan include the following:
• Vegetation management/mowing schedule
• Semi-annual inspections
• Debris check after every storm event
• Benchmark for sediment removal (specific elevations listed)
• Designation of a responsible party
The operation and maintenance agreement must also be signed by the responsible party and
notarized.
Division wetlands unit staff will strive to complete a final technical review within 10 working days of
receipt of the requested information. Completing the enclosed worksheet will greatly decrease the staff
review time. If you have any questions or would like to discuss this project, please contact me at (919)
733-1786.

Inspect monthly, or after every runoff-producing rainfall event, whichever comes first.
A. Remove debris from trash rack.
B. Check and clear the orifice of any obstructions. If a pump is used as a drawdown
mechanism, check for pump operation.
C. Check the pond side slopes, remove trash, repair eroded areas before the next
rainfall event.
D. If the pond is operated with a vegetated filter, check the filter for sediment
accumulation, erosion and proper operation of the flow spreader mechanism.
Repair as necessary.
II. Quarterly
A. Inspect the collection system (i.e., catch basins, piping, grassed swales) for
proper operation. Clear accumulated trash from basin grates and basin bottoms,
and check piping for obstructions.
B. Check pond inlet pipes for undercutting, replace riprap, and repair broken pipes.
C. Reseed grassed swales, including the vegetated filter if applicable, twice a year
as necessary. Repair eroded areas immediately.
III. Every 6 months
A. Remove accumulated sediment from the bottom of the outlet structure.
B. Check the pond depth at various points in the pond. If the depth is reduced to
75% of original design depth, sediment will be removed to at least the original
design depth.
IV. General
A. Mow the side slopes, not including normally submerged vegetated shelf,
according to the season. Maximum grass height will be 6".
B. Cattails, and other indigenous wetland plants are encouraged along the
pond perimeter; however, they must be removed when they cover the entire
surface area of the pond.
C. The orifice is designed to draw down the pond in 2 - 5 days. If drawdown is
not completed in that time, the system may be clogged. The source of the
clogging must be found and eliminated.
Y Y
D. All components of the detention pond system must be kept in good working
order.

To meet the Water Quality requirements, the procedure outlined in the "Stormwater Best
Management Practices" published by NCDENR will be used. This guide gives the
required pond surface area and storage volume to meet an 85% pollutant removal
efficiency. Also, the pond must detain the first 1" of rainfall and release this volume
over a period of 2 to 5 days. Calculations for these requirements are as follows:
Surface area requirements
Post-development impervious percentage = 70%
Normal pool depth = 6 feet
Designed permanent pool elevation = 709
From table 1.1 in the BMP guidelines the required Surface Area to Drainage Area
Ratio (SA/DA) for a permanent pool depth of 6 feet =1.79
Required surface area =1.79/100 x12.37 =0.22 acres
Surface area of pond as designed at permanent pool elevation = 0.22
1"rainfall requirements
Using the runoff volume calculations in the "Simple Method"
Rv = 0.05 +.009 (1)
Rv = 0.05 +.009(90) =.86 (in/in)
Volume = (Design rainfall) (Rv) (Drainage Area)
Volume =1" rainfall x .86 in/in x 1/12 in/ft x 12.37 = 0.886 acre-ft
0.886 acre-ft or 38,617 ft"3 must be released over a 2-5 day period.
Okay
. Using the conic method of volume calculation to determine stage elevation for
___required storage volume: (from Land Development Desktop Pond Volume Calculator)
The volume provided from the normal pool elevation to the 711.28 elevation is approx. 0.89 ac-ft.
(see attached stage storage curve)
Storage elevation = 711.28 or 2.28 feet above permanent pool
Using the conic method of volume calculation to determine permanent pool storage
(from Land Development Desktop Pond Volume Calculator) the total permanent pool volume
equals 26,646 ft" 3. The permanent pool volume of the forebay equals 8,813 ft^3 which equals 33%
of the total volume.

HYDROGRAPHS FOR WATER QUALITY REQUIREMENTS
DESCRIPTION
The following information is used to determine the routed flow rates
from the Market Square Water Quality basin. This information will be used to verify that the
basin meets the water quality requirements by detaining 1" of rainfall for a period of 2 - 5 days.
From previous calculations it has been determined that 1" of rainfall will raise the permanent
pool elevation by 2.28' (See water quality requirements calculations). At this elevation,
the discharge from the outlet structure is 0.63 cfs. Using this value in the table below, the time
of detention for the 1" storm may be determined.

APPROVAL of 401 Water Quality Certification and ADDITIONAL CONDITIONS, WRP
AVTEX Partners
PO Drawer 10287
Greenville S.C. 29603
Dear Sirs:
You have our approval, in accordance with the attached conditions and those listed below, to place fill
material in 0.144 acres of wetlands and 390 feet of streams of waters for the purpose of developing the Market
Square Tract near Gilead Rd and Reese Blvd in Mecklenburg County, as you described in your application dated 2
June, 1999. After reviewing your application, we have decided that this fill is covered by General Water Quality
Certification Number 3108. This certification allows you to use Nationwide Permit Number 26 when the Corps of
Engineers issues it. In addition, you should get any other federal, state or local permits before you go ahead with
your project including (but not limited to) Sediment and Erosion Control, Coastal Stormwater, Non-Discharge and
Water Supply Watershed regulations. This approval will expire when the accompanying 404 or CAMA permit
expires unless otherwise specified in the General Certification. This Certification replaces one issued to you 8 July
1999.
This approval is only valid for the purpose and design that you described in your application except as
modified below. If you change your project, you must notify us and you may be required to send us a new
application for a new certification. If the property is sold, the new owner must be given a copy of this Certification
and approval letter and is thereby responsible for complying with all conditions. If total wetland fills for this
project (now or in the future) exceed one acre, compensatory mitigation may be required as described in 15A NCAC
2H.0506 (h). For this approval to be valid, you must follow the conditions listed in the attached certification and
any additional conditions listed below.
1. Deed notifications or similar mechanisms shall be placed on all lots with remaining jurisdictional wetlands and waters or areas
within 50 feet of all streams and ponds to notify the state in order to assure compliance for future wetland and/or water impact.
These mechanisms shall be put in place within 30 days of the date of this letter or the issuance of the 404 Permit (whichever is
later).
2. An additional conditions is that a final, written stormwater plan including a wet detention basin be approved by DWQ before
wetland (or stream) impacts occur. Also, before any building is occupied at the subject site the approved stormwater treatment
facilities shall be constructed and operational and the approved stormwater management plan be implemented.
3. Sufficient flow must be retained in the remaining channel to retain the natural hydrology.
We understand that you have chosen to contribute to the Wetland Restoration Program in order to compensate
for these impacts to wetlands and/or streams. In accordance with 15A NCAC 2R .0402, this contribution will
satisfy our compensatory mitigation requirements under 15A NCAC 2H.0506(h). According to 15A NCAC 211
.0506(h), feet of restoration will be required. Until the Wetland Restoration Program receives and clears your check
(made payable to: DEHNR - Wetland Restoration Program), wetland or stream fill shall not occur. Mr. Ron Ferrell
should be contacted at 919-733-5083 ext. 358 if you have any questions concerning the Wetland Restoration
Program. You have one month from the date of this Certification to make this payment. For accounting purposes,
this Certification authorizes the fill of 390 feet of streams, in 030833 river and subbasin and 210 feet of
stream restoration are required. Please be aware that the Wetland Restoration Program (WRP) rules
require rounding of acreage amounts to one-quarter acre increments (15A 2R.0503(b)).

RE: AVTEX Partners 401 Water Quality Certification (DWQ Project # 990564)
Dear Mr. Dorney,
Attached is a copy of the 401 Water Quality Certification issued July 8, .1999
authorizing placement of fill into 0.144 acres of wetlands and 390 feet of streams for the
AVTEX Partners project. We are trying to understand the language in the first sentence
of this certification. The sentence currently reads, "You have our approval, in accordance
with the attached conditions and those listed below, to place fill material in 0.144 in 7
acres of wetlands and 390 feet of streams of waters for the purpose of developing the
Market Square Tract...." The portion of that sentence "in 0.144 in 7 acres" appears to be
a typographical error. The words "in 7" do not appear to be accurate to this project. We
believe the sentence should read "You have our approval, in accordance with the attached
conditions and those listed below, to place fill material in 0.144 acres of wetlands and
390 feet of streams of waters for the purpose of developing the Market Square Tract...."
Please review this certification and provide us with a clarification or reissued
certification, if necessary. We respectfully request that this clarification be done as soon
as possible. Thank you for your help in this matter. Please do not hesitate to call me at
[phone] if you have any questions regarding this matter.
Sincerely,
f

Subject: Market Square
DWQ Project No. 990564
Mecklenburg County
The Wetlands Unit staff reviewed the stormwater management plans for the subject project and determined
that additional information is necessary to complete the technical review process. The required additional
information is as follows:
1. Orifice Outlet Structure
Please provide plan details for the outlet structure. Please note that the design should include an
"emergency" drain that is capable drawing down the permanent pool.
2. Forebay
All stormwater wet detention basins are required to have a forebay to facilitate TSS removal. The
forebay should be approximately 20% of the total basin volume. NCDENR Stormwater Best
Management Practices Manual, November 1995, page 4, item Le. Please revise the engineering
plans to meet this requirement.
3. Vegetated Side Slopes
The basin side slopes above the permanent pool down to the vegetative shelf must be stabilized with
vegetation and side slopes no steeper than 3:1 (horizontal to vertical). Landscape information must
be clearly stated on engineering plans.
4. Vegetative Shelf
A vegetative shelf around the perimeter of the pond is required. The shelf shall be gently sloped (6:1
or flatter) and shall consist of native vegetation. Please specify this on the engineering plans.
5. Sediment Removal
If the basin is proposed to be used as a sediment basin during construction, the plans must clearly
indicate that accumulated sediment will be removed prior to implementation as a wet detention
basin.

6. Operation and Maintenance Agreement
An operation and maintenance agreement is required.
A stormwater control structure will not operate as designed without regular maintenance. Typical
requirements for an operation and maintenance plan include the following:
• Vegetation management/mowing schedule
• Semi-annual inspections
• Debris check after every storm event
• Benchmark for sediment removal (specific elevations listed)
• Designation of a responsible party
The operation and maintenance agreement must also be signed by the responsible party and
notarized.
Division wetlands unit staff will strive to complete a final technical review within 10 working days of
receipt of the requested information. Completing the enclosed worksheet will greatly decrease the staff
review time. If you have any questions or would like to discuss this project, please contact me at (919)

Square Tract near Gilead Rd and Reese Blvd in Mecklenburg County, as you described in your application dated 2
June, 1999. After reviewing your application, we have decided that this fill is covered by General Water Quality
Certification Number 3108. This certification allows you to use Nationwide Permit Number 26 when the Corps of
Engineers issues it. In addition, you should get any other federal, state or local permits before you go ahead with
your project including (but not limited to) Sediment and Erosion Control, Coastal Stormwater, Non-Discharge and
Water Supply Watershed regulations. This approval will expire when the accompanying 404 or CAMA permit
expires unless otherwise specified in the General Certification.
This approval is only valid for the purpose and design that you described in your application except as
modified below. If you change your project, you must notify us and you may be required to send us a new
application for a new certification. If the property is sold, the new owner must be given a copy of this Certification
and approval letter and is thereby responsible for complying with all conditions. If total wetland fills for this
project (now or in the future) exceed one acre, compensatory mitigation may be required as described in 15A NCAC
2H .0506 (h). For this approval to be valid, you must follow the conditions listed in the attached certification and
any additional conditions listed below.
1. Deed notifications or similar mechanisms shall be placed on all lots with remaining jurisdictional wetlands and waters or areas
within 50 feet of all streams and ponds to notify the state in order to assure compliance for future wetland and/or water impact.
These mechanisms shall be put in place within 30 days of the date of this letter or the issuance of the 404 Permit (whichever is
later).
2. An additional conditions is that a final, written stormwater plan including a wet detention basin be approved by DWQ before
wetland (or stream) impacts occur. Also, before any building is occupied at the subject site the approved stormwater treatment
facilities shall be constructed and operational and the approved stormwater management plan be implemented.
3. Sufficient flow must be retained in the remaining channel to retain the natural hydrology.
We understand that you have chosen to contribute to the Wetland Restoration Program in order to compensate

Rv = 0.05 +.009(90) =.86 (in/in)
Volume = (Design rainfall) (Rv) (Drainage Area)
Volume = 1" rainfall x .86 inrn x 1/12 in/ft x 12.37 = 0.886 acre-ft
0.886 acre-ft or 38,617 ftA3 must be released over a 2-5 day period.
Using the conic method of volume calculation to determine stage elevation for
required storage volume: (from Land Development Desktop Pond Volume Calculator)
The volume provided from the normal pool elevation to the 712.70 elevation is approx. 0.89 ac-ft
(see attached stage storage curve)
Storage elevation =4712..70: or Z70 feet above permanent pool

Threatened and Endangered Species Assessment for the Market Square
Tract
Mecklenburg County, North Carolina
May 17,1999

' 1.0 Introduction
The following report details methods used and an assessment of survey results for a
' threatened and endangered (T&E) species survey and habitat assessment for the
approximately 15.749 acre Market Square site. The T&E species survey was conducted to
determine the occurrence of or the potential for animal and plant species listed as federally
' threatened or endangered to exist on the proposed site. Completion of this survey was
directed by and complies with current state and federal regulations [Federal Endangered
Species Act of 1973 (16 USC 1531-1543) and the North Carolina Endangered Species Act
(N.C.G.S. Sect. 113 article 25) and North Carolina Plant Protection and Conservation Act
of 1979 (N.C.G.S. Sect. 19b 106: 202.12-22).
' The referenced site is located adjacent to Gilead Road approximately 0.7 miles west of
Interstate 77 in Mecklenburg County, North Carolina (Figure 1). The site is bounded by
Gilead Road to the south, three commercial buildings to the east, undeveloped woodlands
' to the north, and undeveloped abandoned pasture to the west. Access to the is available from
Gilead Road.
2.0 Methodology
' A preliminary protected species survey was conducted on April 27, 1999, on the Market
Square site by Newkirk Environmental, Inc. to determine potential for occurrences of animal
and plant species listed as endangered or threatened by current Federal or State regulations.
' Recent correspondence solicited from The North Carolina Natural Heritage Program dated
April 28, 1999, provided existing data concerning the presence or potential occurrence of
' threatened or endangered species in Mecklenburg County, North Carolina (Appendix A).
The USFWS lists the following three Federally endangered plant species and one Federally
endangered mussel as occurring in Mecklenburg County: Michaux's sumac (Rhus michauxii),
' smooth coneflower (Echinacea laevigata), Schweintz's sunflower (Helianthus schweinitzii),
and the Carolina heelsplitter (Lasmigona decorata). As noted, NCDENR has no
documentation of any rare, threatened or endangered species or high quality natural habitats
' within the referenced tract (Appendix A). NCDENR also notes that their records are not
deemed to be complete and should not be assumed to be comprehensive. Therefore, field
surveys should be conducted for thorough evaluations. The species listed above were
' included in the surveys and assessment.

' The protected species audit consisted of a pedestrian survey by Newkirk Environmental staff.
During field surveys, site habitats were identified and compared with recognized habitats for
each of the four species potentially occurring on the site. Additionally, observed flora and
' fauna were identified to the taxonomic unit level necessary to determine if the observed
specimen was a protected species.
' 3.0 Habitat Classification
' During field surveys, four primary habitats: abandoned pasture, upland hardwood, wetland
hardwood, and upland shrub thicket, were identified on the property. The following is a
description of each of the major habitat types identified on the referenced site and its
likelihood to harbor or support listed species.

I I
H

3.1 Abandoned Pasture
Abandoned pasture habitat is located on the central and southern portion of the site.
The field contains scattered red cedar and black cherry saplings. The herbaceous
layer is dominated by broom sedge (Andropogon virginicus), blackberry (Rubus sp.),
Japanese honeysuckle, Panicum spp. and others grasses. This field also contains a
few scattered Autumn olive (Elaeagnus umbellata). Kudzu is also well established
on the eastern edges of the pasture and observed elsewhere throughout the site.
3.2 Upland Hardwood
The upland hardwood community consists of a small area between the pasture and
the identified wetland forest. Much of this community is located on the steep banks
which transition to from the pasture to the wetland. The overstory of this community
is dominated by several large mature trees including white oak (Quercus alba) and
sycamore (Platanus occidentalis). The understory is dense and has a greater
diversity of plant species; saplings observed include sweetgum (Liquidambar
styraciflua), red maple (Acer rubrum), willow oak (Quercus phellos), water oak
(Quercus nigra), black cherry (Prunus serotina), and eastern red cedar. Plants
observed in the herbaceous layer include Virginia creeper (Parthenocissus
quinquefolia), poison ivy (Toxicodendron radicans), Japanese honeysuckle (Lonicera
japonica), trumpet creeper (Campsis radicans), and greenbriar (Smilax sp.) The
upland hardwood forest is not suitable habitat for any of the listed species.
2

' 3.3 Upland Shrub Thicket
The upland shrub thicket located in the northwest corner of the site is dominated by
' a dense stand Autumn olive (Elaeagnacs umbellata). Other species in the
shrub/sapling layer observed include red cedar and red maple. Herbaceous plants
observed were poison ivy (Toxicodendron radicans), blackberry (Rubus sp.), and
grape (Vitis sp.). The densely vegetated shrub layer is not suitable for any of the
listed species.
' 3.4 Wetland Forest - Hardwood Dominated
' This habitat occurs in wetland flat areas associated with the small intermittent
stream located in the northern portion of the site and comprises approximately
0.287 acres. The overstory is dominated by yellow poplar, black willow, and
' green ash (Fraxinus pennsylvanica). Plants observed in the herbaceous layer
include Virginia creeper, jewel weed (Impatiens capensis) and soft rush (Juncus
effusus). Kudzu is also observed climbing onto trees within the wetlands. The
wetlands are not suitable for any of the listed species.
3.5 Soils
' Soils mapped by the Natural Resources Conservation Service (MRCS) Mecklenburg
County Soil Survey, Map 2, for the Market Square site include: Cecil sandy clay
' loam (8-15 percent slopes) and Davidson sandy clay loam (2-8 percent slopes).
These soil types have been classified as medium to strongly acid.
i 4.0 Listed Species and Acknowledged Habitats
The following is a brief description of each listed species included in the survey, its
recognized habitat and comments regarding survey results for that species:
4.1 Michaux's sumac, federally listed as an endangered species, is found in sandy
or rocky, open woods in association with basic soils, usually on ridges that have
' been disturbed through clearing. Flowering period: June. Apparently, this plant
survives best in areas where some form of disturbance has provided an open
area. Eleven of the plant's 16 remaining populations are on highway rights-of
' way, roadsides, or on the edges of artificially maintained clearings. Two other
populations are in areas with periodic fires, and two more populations exist on
sites undergoing natural succession. One population is situated in a natural
opening on the rim of a Carolina bay. The preferred soil of this species is
circumneutral.
' 4.2 Smooth coneflower, federally listed as an endangered species, is a rare plant
found in meadows open woods, cedar barrens, roadsides, clear-cuts, dry
limestone bluffs, and power line rights-of-way, usually on magnesium and

' 5.0 Conclusion
During completion of threatened and endangered species habitat assessments for the Market
Square Tract, suitable habitat for species listed as potentially occurring in the site was not
found. Based upon the available habitat, it is the opinion ofNewkirk Environmental, Inc. that
federally and state protected species are not present within the site. As such, development
of the proposed Market Square site is not likely to cause and adverse impact to any
threatened or endangered species or potential habitat for threatened and endangered species.
Although no threatened and endangered species were identified during this survey,
because of the transitory nature of some of the listed threatened and endangered species
and the particular flower/fruiting periods of some plants, it is possible that endangered
' species populations and locations may change over time. Therefore, any potential
findings at a later date should be fully investigated and coordinated to prevent potential
' adverse impacts.

SIGNIFICANT NATURAL HERITAGE AREAS
January 1999
Introduction
North Carolina Natural Heritage Program compiles the N.C. Department of Environment and Natural
Ifeesources' list of "Significant Natural Heritage Areas" (SNHA) as required by the Nature Preserves Act (NCGS
Chapter 113A-164 of Article 9A). The list is based on the program's inventory of the natural diversity in the
I tate. SNHA are evaluated on the basis of the occurrences of rare plant and animal species, rare or high quality
atural communities and special animal habitats. The global and statewide rarity of these elements and the
quality of their occurrence at a natural area relative to other occurrences determine its significance rating.
NHAs included on this list are the best known representatives of the natural diversity of the state and therefore
ave priority for protection. Inclusion on this list does not mean that public access exists or is appropriate.
ermission of the land owner is recommended in all cases. Inclusion on this list does not confer protection to a
natural area, nor does it give it regulatory status. The list includes both protected and unprotected areas. This list
f natural areas and their significance ratings are based on the best available information as derived from the
atural Heritage Program staff and databases. More information on these natural areas may be obtained from
the Natural Heritage Program.
organization of the List
atural Areas
Srhe following list of 1497 of North Carolina's of North Carolina's most significant natural areas is organized by
county, and within each county the natural areas are ordered by ratings of national, statewide, or regional (greater
han local) significance. This list does not include natural areas considered to be of local importance.
Natural Area Significance (SiO
Nationally significant natural areas contain examples of natural communities, rare plant or animal
populations, or geologic features that are among the highest quality or best of their kind in the nation, or
clusters of such elements that are among the best in the nation.
- Statewide significant natural areas contain similar ecological resources that are among the highest quality
occurrences in North Carolina. There may be better quality representations or larger populations
elsewhere in the nation, including possibly a few within the state.
t - Regionally significant natural areas contain natural elements that may be represented elsewhere in the
state by better quality examples, but which are among the outstanding examples in their geographic
region of the state. A few better examples may occur in nationally or state significant sites.
Organization of List
1frequently, related natural areas occur in clusters. The occurrence of a natural area in association with others
creases its long-term viability and ecological significance. Such clusters are designated as macrosites and may
range in size from 500 acres to 64,000 acres or more. Macrosites contain lands which normally would not be
f cluded in a natural area but which are important for consolidating the cluster. Where one or more macrosites
ll within a region, a megasite is designated. Macrosite and megasite designations reflect ecological
relationships rather than ownership.
ften natural areas do not occur in clusters. These are referred to as single or "stand alone" sites. The size of
khese natural areas varies from one to a several thousand acres. The avast majority of the lands within a site is of
natural area quality though dirt roads or small areas of converted or developed land may be imbedded. State
Parks, Game Lands, or other large areas managed for conservation by a single agency may be identified in this
list as a single SNHA.

Nationwide 26 Permit Application
Proiect Location, Descrivtion and Purpose 012, 13 & 14
The project site is a 15.79 acre tract of land located near the intersection of Gilead Road and
Interstate 77 north of Charlotte, NC. The majority of the tract is a fallow pasture characterized by
open grassy field with scattered saplings. Approximately 0.287 acres of freshwater wetlands are
located along the northern property line. Wetland boundaries have been surveyed and verified by
the US Army Corps of Engineers on April 13, 1999 (see enclosed plat). Within the identified
wetland is the upper portion of an small unnamed tributary that drains to Torrence creek which is
located approximately 1000 feet northwest of the site. During site reviews conducted with Mr.
Samar Bou-Ghazalle, DWQ, the upper 180 feet of the stream was determined to "lack aquatic
biological indicators as it is characterized by intermittent gullies. The remaining portions of the
wetland/stream are characterized by a narrow (2 foot) shallow stream with associated forested
wetlands.
The property owner and applicant, AVTEX Partners, plans to construct and develop a multi-use
shopping center to include a grocery store and associated small commercial businesses on the
property. Economic feasibility, land availability and market area considerations were reviewed in
selection of the proposed site. The project engineer, ColeJenest & Stone, has recently completed a
master plan for the development (see enclosed plan and drawings).
In order to accomplish the stated purpose, AVTEX proposes to impact, by filling, 0.144 acres of
freshwater wetlands including 390 feet of stream channel. Impacts to site wetlands are necessary
to accomodate building and parking requirements. Every effort to minimize impacts to the wetlands
has been made. Impacts have been minimized by relocating on-site stormwater detention areas
outside of wetlands and preserving higher value wetland/stream areas. The proposed plan includes
impacts only to the upper reaches identified by Mr. Bou-Ghazelle and approximately 210 feet of
stream/wetland below the division of these areas. The remaining stream channel and associated
forested wetlands will be left in their natural condition.
Compensatory mitigation for impacts to approximately 210 linear feet of stream channel is proposed
through appropriate contributions to the NC Wetlands Restoration Program as per guidance in the
Public Notice regarding mitigation options.

Dear Mr. Martin:
On April 22, 1999, I met with you at the subject site to conduct an evaluation of the stream feature present
on the wester edge of the property. This project is referenced by the Raleigh Regional Office as NBRRO
99-086. It was determined that the feature is the headwaters of Richlands Creek and is indicated on the
Wake County Soils and the U.S.G.S. maps as at least an intermittent stream and therefore subject to the
Neuse River Basin: Nutrient Sensitive Waters Management Strategy; Protection and Maintenance of Existing
Riparian Areas, Administrative Code T15A:02B.0233 (NCAC 0233).
The stream has been delineated on the map received and the area applicable to protection under the Neuse
Buffer Rules begins at NBR Flag 1 at the edge of the property along Trinity Road toward the north to Flag
8.
Please be reminded that the riparian buffer is protected in two zones totaling fifty feet of protection. In
accordance with the Rule, sheet flow from stormwater must be maintained, to the maximum extent practical,
through dispersing concentrated flow and/or re-establishment of vegetation to maintain the efficacy of the
riparian area.
Thank you for your attention to this matter and if this Office can be of any assistance or if you have
additional questions, please do not hesitate to contact us.
Unc ly,
Steve Mitchell
