Footnotes:
1 When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
2 In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.
II. REQUIRED ITEMS CHECKLIST
The following checklist outlines design requirements per the Stormwater Best Management Practices Manual
(N.C. Department of Environment, Health and Natural Resources, February 1999) and Administrative Code
Section: 15 A NCAC 2H .1008.
Initial in the space provided to indicate the following design requirements have been met and supporting
documentation is attached. If the applicant has designated an agent in the Stormwater Management Permit
Application Form, the agent may initial below. If a requirement has not been met, attach justification.
Applicants Initials
P a. The permanent pool depth is between 3 and 6 feet (required minimum of 3 feet).
?6 b. The forebay volume is approximately equal to 20% of the basin volume.
c. The temporary pool controls runoff from the design storm event.
d. The temporary pool draws down in 2 to 5 days.
l A e. If required, a 30-foot vegetative filter is provided at the outlet (include non-erosive flow
calculations)
f. The basin length to width ratio is greater than 3:1.
P? g. The basin side slopes above the permanent pool are no steeper than 3:1.
P? ?+ h. A submerged and vegetated perimeter shelf with a slope of 6:1 or less (show detail).
i. Vegetative cover above the permanent pool elevation is specified.
?" J. A trash rack or similar device is provided for both the overflow and orifice.
P144 k. A recorded drainage easement is provided for each basin including access to nearest right-
of-way.
Pe-G 1. If the basin is used for sediment and erosion control during construction, clean out of the
basin is specified prior to use as a wet detention basin.
?Gqi m. A mechanism is specified which will drain the basin for maintenance or an emergency
III. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the
vegetated filter if one is provided.
This system (check one) 0 does I does not incorporate a vegetated filter at the outlet.
This system (check one) 0 does • does not incorporate pretreatment other than a forebay.
Form SWU-102 Rev 3.99 Page 2 of 4
Maintenance activities shall be performed as follows:
After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
2. Repair eroded areas immediately, re-seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain
proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of
in an appropriate manner and shall be handled in a manner that will not adversely impact water quality (i.e.
stockpiling near a wet detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads , feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 7. feet in the forebay, the sediment shall be removed.

5. Remove cattails and other indigenous wetland plants when they cover 50% of the basin surface. These
plants shall be encouraged to grow along the vegetated shelf and forebay berm.
6. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through
the emergency drain shall be mihimized to the maximum extent practical.

Fluid discharged from an orifice in a tank gets its initial
velocity from the conversion of potential energy. Af-
ter discharge, no additional energy conversion occurs,
and all subsequent velocity changes are due to external
forces.

C-10 RED TOP
CANAL GATE
This gate is designed for use on canal and pipeline
systems which operate at low "heads" and when: a
moderately priced gate is desired. Typical installations
include: frame turnouts, control of industrial wastes,
drainage and for tide control.
Construction is of grey cast iron with an all-bolted steel
frame. The standard stem is of a special leaded steel
which resists corrosion. The stem is operated at the
structural frame top by a heavy cast-bronze lift nut and
a cast iron wheel.
Adjustable cast iron wedge blocks, held securely in place
by two machine bolts, assure a dependable seating
closure with a practical degree of water tightness. The
cast iron seats are machined or ground. A locking
device at the lift nut and a solid rim "easy-grip" hand-
wheel are standard features.
Optional materials include: bronze seats; stainless steel
structural frame and bolts; stainless steel or brass
stems; and special epoxy, coal tar or ASTM galvanized
coatings.
When desired, design variations in stem diameter, pitch
and thread rotation are available to match existing
equipment. Extended stems, special lifts, oil seals, stem
guides and limit nuts are a few of the optional items
available for use with these gates.
Special variations quoted upon application. See specl-
fication pages for additional information and details.
Special materials available include: "Ni-Resist" iron cast-
ings, stainless steel structuralframe and assembly bolts;
total galvanizing per ASTM A-123; coal tar, and epoxy
coatings.

CL-10 CANAL
GATE
FLAT COVER (SLIDE)
WITH SQUARE BOTTOM
Waterman CL-10 Canal Gates are identical to our
model C-10 Gates with the exception of the cast iron
cover (slide) which is of a flat plate type construction with
ribs reinforcing its face, to withstand the maximum
heads as noted for our C-10 gates. This gate cover also
features a square bottom design, which allows a more
open "clog-free" flow at points of initial opening. The
seat being only slightly raised above the cover plate
surface helps prevent trash from collecting behind the
cover which can cause difficulty in operation.
Available with threaded thrust nut for true NRS applica-
tion. All parts are interchangeable with our Standard C-
10 gate. CL-10 gates are available in sizes 8" - 42".

pipe with rivets, bolts or a special field installation band.
Using mounting bolts, the gate frame with a special
double ring tapered spigot is drawn onto the pipe;
wedging the pipe, gasket and frame together thus
locating, holding, and sealing the unit Special pipe ends
are not required.
Short stubs and band couplers are eliminated. Field
installation of factory-assembled gates becomes pos-
sible without special tools or power equipment. Use of
"R-Sear' spigot eliminates special handling of pipewhich
is normally required when gates are attached.
The taper gasket seals as it holds, often eliminating need
for mastic or tar at this joint
r
y
Lugs hold in place with the
special field attaching band.
Slip the lugs and band over
end of the pipe and tighten
onto second valley with
lugs aligned to receive the
mounting bolts.
C40R
Lugs shown bolted in
place. Simply align the
lugs, drill and bolt or rivet
in position. Tighten gate
frame and gasket into
place with the mounting
bolts provided.

Dear Mr. Praechtl:

NC ENR
NORTH CAROLINA DEPARTMENT OF
ENVIRONMENT AND NATURAL RESOURCES
April 27, 2000
DWQ Project # 000267
Mecklenburg County
' The Division of Water Quality has reviewed your plans for the discharge of fill material into 0.94
acres of wetlands and 1,790 linear feet of streams located at Pulte Homes at Ballantyne in Mecklenburg
County for a commercial and residential development as described in your application dated March 3, 2000.
Insufficient evidence is present in our files to conclude that your project must be built as planned in waters
and/or wetlands in accordance with 15A NCAC 2H .0506. Therefore, unless modifications of the proposal
are made as described below, we will have to move toward denial of your 401 Certification as required by
15A NCAC 2H .0507(e) and will place this project on hold as incomplete until we receive this additional
information, we are requesting (by copy of this Letter) that the U.S. Army Corps of Engineers place your
project on administrative hold.
This project will require compensatory mitigation as described in 15A NCAC 2H .0506(h). Your
mitigation proposal is insufficient because:
1. It is not clear what acreage of wetlands were previously impacted for earlier phases of
this project.
2. The distances that the wetlands you proposed from the nearest "blue line" on the 1:24,000
USGS topographic map. The later information is needed to determine the required
mitigation ratio.
Please respond within three weeks of the date of this letter by sending a copy of this information to
me and to the Mr. Samar Bou-Ghazale, Mooresville Regional Office at [phone]. If we do not hear
from you in three weeks, we will assume that you no longer want to pursue this project and we will consider
the project as withdrawn. I can be reached at 919-733-9646 if you have any questions.

SUBJECT: Review of 404/401 Application by Pulte Homes, Mecklenburg County.
The applicant is requesting a letter of concurrence from the North Carolina Wildlife
Resources Commission (NCWRC) to obtain a 404 Permit and 401 Certification. These
comments are provided in accordance with provisions of the Clean Water Act of 1977 (33 U.S.C.
466 et. seq.) and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C.
661-667d). Impacts from the development will be 0.94 acres of wetlands and 1790 linear feet of
stream. Approximately 0.75 acres of wetlands will be created in conjunction with detention
basins.
The North Carolina Wildlife Resources Commission (NCWRC) continues to be
concerned about the fragmentation and loss of forested areas, headwater streams and woodlands
as development occurs in areas near the City of Charlotte and in or near Mecklenburg County.
We appreciate the efforts to protect water quality by providing stormwater detention and
treatment. However, the NCWRC does not encourage the utilization of existing waters or
wetlands for water quality treatment facilities.
If relocation of the stream is not economically feasible or practicable, we recommend that
the wet detention facility include vegetated littoral shelves for aquatic edge habitat as routinely
required in 401 Certifications. In an effort to restore avian and terrestrial habitats as well as
enhance aquatic/detritus habitats in the detention facility, we recommend that the applicant
provide for the restoration of tree and shrub species similar to those currently found on the site
(red maple, sweetgum, tulip poplar, dogwood). Native species such as wild cherry, hickory and
oak may be preferred over the above due to structural concerns. These trees and shrubs should
be planted around and on the upper third of the detention structure, excluding the dam. They
should provide habitat benefits that could offset those functions lost by development, partially
restore aquatic habitats, reduce exposure of the water surface to sunlight thereby minimizing
. . Pulte Homes at Ballantyne.doc 2 03/16/00
thermal pollution, provide essential summer and winter habitats as well as provide an
aesthetically pleasing green space which should actually enhance property values. Essentially,
these plantings could provide water quality and habitat benefits as well as provide a park area for
residents. Land values should also be enhanced.
Additionally, instead of using the typical fescue or grasses, the upper interior and exterior
of the structure should be planted with the following mix:
Spring/Summer Mixture, May 1 - Sept. 15 Fall/Winter Mixture, Sept. 15 - April 30
Browntop millet 20 lbs/a Rye grain 120 lbs/a
Korean lespedeza* 20 lbs/a Korean lespedeza* 20 lbs/a
Shrub lespedeza 1 lb/a Shrub lespedeza 1 lb/a
Switchgrass 10 lb/a Partridge pea 10 lb/a
* On slopes less than 3:1 use Korean lespedeza
On slopes greater than 3:1 use Crown Vetch
Add one of the following to the above m ixture
Crown Vetch 5 lbs/acre
Ladino Clover 5 lbs/acre Lime & fertilize disturbed areas according
Alfalfa 5 lbs/acre to NCRS soil test and recommendations.
(Note: Mowing should be limited to early spring and should only occur as needed to prevent tree growth
on the dam or other areas. Mowing on a 2-3 year schedule should suffice.)
Trees and shrubs (1 year bare root seedlings) should be planted randomly at a minimal
rate of 100 trees per acre on the top and upper portions of the structure and at a minimal rate of
150 per acre around the normal water elevation and littoral shelf area. The following list of tree
species may assist in providing habitat benefits:
Loblolly Pine* Red Cedar Black Gum American Holly Dogwood
Hickory Sumac White Oak Willow Oak Red Maple**
Swamp Chestnut Oak Viburnum Green Ash Ironwood Black Cherry
Persimmon Water Oak Spice Bush Silky Dogwood Willow (sp)
Other species may be utilized depending on site requirements and availability. Pines* should not exceed
15% of the reforestation. No more than 20% of the tree species will be of a single species. An 80%
success rate is acceptable over five years. Large or fast growing trees like Sycamore and Maple** may not
be appropriate around detention facilities.
The above recommendations should be considered for the multiple benefits that they can
provide to the community and to the environment. Initial costs should not be prohibitive and the
long-term costs should be reduced as constant mowing would not be necessary in the naturalized
areas. Thank you for the opportunity to review and comment on this project. If you have any
questions regarding these comments, please contact me at 336/769-9453.

Ballantyne Commons West
Dear Mr. St. John:
December 12, 2000

{ 1_MI?V TV
Ballantyne Commons West is approximately an 82 acre parcel of land located in southern
Mecklenburg County within the city limits of Charlotte at the southwest corner of the
intersection of relocated U. S. Hwy. 521 and Ballantyne Commons Parkway. The site is zoned
CC (Commercial Center), with allowances for a total of 1800 dwelling units. The intended use
of this site consists of townhomes (approximately 500 units).
This stormwater management plan has been prepared based on information contained in a
May 9, 2000 letter from Leonard S. Rindner to Mr. John Domey and the May 23, 2000 approval
of 401 Water Quality Certification for this project. Copies of these documents are attached for
your reference.
There are three drainage basins for this site. Drainage Area 1 totals 50 acres and drains to a
proposed wet detention basin to be located adjacent to an existing stream and wetlands along the
southern property line. Drainage Area 2 totals 62 acres and drains to an existing 72" Corrugated
Metal Pipe (CMP) located on the northern property line, which carries collected runoff from our
site under Ballantyne Commons Parkway to McAlpine Creek. Drainage Area 3 totals 500 acres
and drains to an existing 9'x9' Reinforced Concrete Box Culvert (RCBC), which carries
collected runoff from our site and off-site areas under Ballantyne Commons Parkway to
McAlpine Creek. Stormwater runoff from our site will sheet flow over asphalt roadways,
concrete sidewalks, roofs and grassed areas to a series of catch basins which will transport it via
underground pipe systems to either the existing stream/wetlands area or proposed wet detention
basin.
Drainage Area 1 - Proposed Wet Detention Basin
The natural drainage area for the wet detention basin is approximately 38 acres. However, in
order to maximize the water quality benefits a wet detention basin provides, anticipated future

grading will increase the drainage area to approximately 50 acres. The proposed drainage area
consists of 37.2 acres of on-site (townhomes @ 70% impervious), 1.3 acres from an existing
First Union Bank (@ 70% impervious) and 11.5 acres from Ballantyne Country Club (0.5 acre
single family lots @ 50% impervious). Therefore, the composite percent impervious used for the
design of the wet detention basin is 65.4%.
The required storage volume (temporary pool, runoff from the 1" rainfall event) is 115,906 cf.
The proposed basin will be constructed adjacent to identified jurisdictional waters of the U.S.
The intent is to leave the stream and wetlands in their natural state (except whey
be constructed over the existing stream), construct the w on basin and only inundate the
fisting duns ictiona waters urmg r fall events. This will allow continued normal operation
Z of the stream and wetlands. The existing elevation surrounding the stream and wetlands is
approximately Elev.=570.0. Therefore, proposed grading begins approximately 2' from the
existing 570 contour with a proposed 570 contour forming the normal water surface of the
proposed wet detention basin (permanent pool elevation). Approximately 46,600 sf of surface
area is provided at Elev.=570.0 and according to the NCDENR Stormwater Best Management
Practices (April 1999) Table 1.1 SA/DA Ratios and 65.4% impervious surfaces, the required
permanent pool depth based on the provided surface area is 5' (required SA=41,478 sf). The
proposed basin has a 6' deep permanent pool, with the bottom of basin Elev.=564.0. The basin
has 3:1 (horizontal: vertical) maximum side slopes, except for a 2' deep shallow sloped shelf at
6:1 which surrounds the permanent pool (Elev.=568 to 570). The shelf will be planted with
wetland species plants (including but not limited to: Arrow arum, Common Three-Square,
Duckweed, Pickerelweed, Pond Weed, Smartweed, & Waterweed).
The principle spillway is a 48" CMP riser, anchored below the bottom of the permanent pool
with a 5'x5'x18" concrete pad, extending above the permanent pool to Elev.=572.5 with a
standard trash rack. The temporary pool Elev.=572.3 (runoff from the 1" rainfall event). The
release of this volume will be controlled by a 3" diameter CMP reversed slope orifice attached to
the riser at Elev.=570.0 and extending down into the permanent pool. This orifice is designed to
drawdown the temporary pool in approximately 3.2 days, which is within the NCDENR
guidelines of 2-5 days. Larger storm events are controlled by the 48" CMP riser and 36" CMP
outlet. Attached to the 48" riser at the bottom of the permanent pool (Elev.=564.0), is an 8"
diameter canal gate with a handwheel. The canal gate is sized to empty the permanent pool in
approximately 12 hours in order to perform routine maintenance to the basin or its control
structures. A 20' wide riprap lined emergency spillway is provided at Elev.=574.0. The
maximum water surface elevation for the 100-year storm is Elev.=575.01. Proposed top of dam
is Elev.=576.0, therefore 1' of freeboard is provided for the 100-year storm event.
The basin is designed with a sediment forebay into which stormwater runoff from the on-site
portion of Drainage Area 1 will be discharged. The forebay will be constructed to the same
depth as the permanent pool (Elev.=564 to 570) and will be defined by a berm (which will be
planted with wetland species plants listed above) at Elev.=572.0 with a 20' wide spillway at
Elev.=570.0 (permanent pool elevation). The forebay volume is 58,705 cf or approximately 20%
of the total required basin volume (171,110 cf permanent pool volume plus 115,906 cf temporary
pool volume).

Drainage Area 2 - Existing 72" CMP
The existing drainage area for the existing 72" CMP is approximately 65 acres, consisting of 30
acres of on-site (townhomes @ 70% impervious) and 35 acres from an existing office park (@
75% impervious) located across Ballantyne Commons Parkway. However, anticipated future
grading will reduce this drainage area by approximately 3 acres (3 acres of on-site area will go to
Drainage Area 1). Just upstream from the 72" CMP inlet are approximately 0.27 acres of
existing wetlands and approximately 500' of stream, which are both to remain undisturbed. We
are proposing to add three small pockets of wetlands adjacent to the existing wetlands and
stream, for a total of 0.52 acres. Also, a 35' Riparian Buffer measured from the edge of the
existing stream and proposed wetlands will be established. Finally, the existing rock check dam
immediately upstream from the existing 72" CMP will be repaired/replaced as necessary to
insure that it continues to impede stormwater flow and dissipate energy. Stormwater runoff from
on-site will be collected and piped through existing and proposed pipe systems to the
wetland/stream area.
Drainage Area 3 - Existing 9'x9' RCBC
The total drainage area to the existing box culvert is approximately 500 acres, which includes
Drainage Area 1 and 55 acres of on-site drainage area. Stormwater runoff from the on-site
portion of Drainage Area 3 will be collected and piped through proposed pipe systems to the
edge of the 75' buffer, where it will be released and allowed to sheet flow into the existing
stream. Riprap energy dissipation devices will be used at all pipe outfalls.
Attached you will find application forms, plans, details and calculations for the design and
construction of the proposed stormwater management plan. The proposed road and building
layout shown is preliminary and subject to change. Therefore, proposed drainage areas are
approximate and conservative as estimated from the preliminary layout. They will vary slightly
due to final layout and grading. A detailed storm drainage system (i.e. catch basins and pipes)
will be designed as individual project phases are designed. However, the basic concept of this
stormwater management plan shall dictate how and where pipe outfalls are placed. Please
review the enclosed items and do not hesitate to call if you have any questions or require
additional information.

DWQ Project Tr 000267
Mecklenburg County
The Division of Water Quality has reviewed your plans for the discharge of fill material into 0.94
acres of wetlands and 1,790 linear feet of streams located at Pulte Homes at Ballantyne in Mecklenburg
County for a commercial and residential development as described in your application dated March 3, 2000.
Insufficient evidence is present in our files to conclude that your project must be built as planned in waters
and/or wetlands in accordance with 15A NCAC 2H .0506. Therefore, unless modifications of the proposal
arc made as described below, we will have to move toward denial of your 401 Certification as required by
15A NCAC 2H .0507(e) and will place this project on hold as incomplete until we receive this additional
information, we are requesting (by copy of this letter) that the U.S. Army Corps of Engineers place your
project on-administrative hold.
This project will require compensatory mitigation as described in 15A NCAC 2H .0506(h). Your
mitigation proposal is insufficient because:
1. It is not clear what acreage of wetlands were previously impacted for earlier phases of
this project.
2. The distances that the wetlands you proposed from the nearest "blue line" on the 1:24,000
USGS topographic map. The later information is needed to determine the required
mitigation ratio.
Please respond within three weeks of the date of this letter by sending a copy of this information to
me and to the Mr. Samar Bou-Ghazale. Mooresville Regional Office at [phone].' If we do not hear
from you in three weeks, we will assume that you no longer want to pursue this project and we will consider
the project as w1-uhu.a"vvn. I car be lc hod at 919-7332-1,1646 if you have ary questions.

Dear. Sirs:
On behalf of my clients, Mr. Tun Praechtl of Pulte Home Corporation, I am providing you with the
additional information and explanation you requested concerning the proposed mixed use. development.
Attached please find :
USGS Map - 2000' scale
2• USGS Map - 500' scale
3. Site Plan showing approximate location of wetland impacts in 1994. This area was review by me
and Mike Parker in the field on June 1, 1994. Based on this preliminary review, these wetlands were
found to be degraded (rutted; Hurricane Hugo impacts; overgrowth of rose and ligustrwn) and high in the
drainage area. At th_ at time it was determined that the water quality functions of this wetland area could
be mitigated with the development of a stormwater management facility with a littoral zone. Mike Parker
is likely to remember this meeting due a remark that a contractor on the site made to us regarding'his
prediction of our political affiliations ("are you with Clinton ").
The impacts to this wetland area were mitigated for through the creation of wetlands along McAlpine
Creek tributary. This created wetland is fully functioning and provides water storage, bank stabilization,
pollution removal, and is a viable aquatic resource. Also, all commercial projects throughout Ballantyne
have strictly adhered to a stormwater management plan which includes several wet detention basins. A
minimum 25' buffer was also implemented adjacent to preserved streams and wetlands.
Proposed Wetland and &'P M maa_
The purpose of the stream and wetland impacts is to create a stormwater storage and treatment facility for
the project as well as an amenity. Steep topographic conditions makes avoidance of the this area not
practicable. The riffle pool complex stream will not be impacted by the project and will be protected by a
50' buffer on the project side of the stream.

Minimization and Proposed Compensatory Mitigation
A mitigation plan is proposed for a "no net loss" of wetland and stream habitat, value, and function to the
extent feasible on this site. The proposed wetlands will be created to provide water storage, bank
stabilization, pollutant removal, and aquatic resource values as described in the Fourth Version -
Guidance for Rating Values of Wetlands in North Carolina. Impacts to important streams by grading,
fill; and culverting to important streams does not exceed 150 If. Mitigation is provided for wetland
impacts.

Wetland Mitigation includes approximately ±0.75 acres of wetlands will be created in conjunction with
the dry and wet detention basins.
As described in the application the wetland mitigation proposal is to develop areas of headwater wetlands
in various forms which are saturated within the root zone or inundated for a significant portion of the
growing season. The zones will be based on the expected saturation and inundation of the particulate zones
and tolerances and include Bottomland Hardwoods, Scrub/Shrub, Emergent, and Aquatic Zones.
STORMWATER MANAGEMENT PLAN
A Stormwater Management Plan will be designed and implemented for the project to meet the 401 Water
Quality Certification requirements. Stormwater management becomes necessary when increasing the
impervious area within an existing natural area. The planners will utilize information and guidelines
provided by the North Carolina Department of Environment and Natural Resources Water Quality Section
in developing this stormwater wetland. Wet detention basins shall be the primary treatment system for
stormwater runoff from paved surfaces and landscaping on commercial, office, business, and institutional
parcels. The wet detention basins will be designed to attenuate the first inch of rainfall over a 24 hour
period. Water will be released over a 2 to 5 day period Discharge velocity of will be less than five cfs
from the end of the dissipation device. A littoral zone/forebay will be incorporated into the design of the
ponds to encourage additional nutrient removal. The planners will utilize information and guidelines
provided by the North Carolina Department of Environment, Health, and Natural Resources in developing
the design of wet detention basins using the Table 1 1 in the Stormwater Best Management Practices
NCDENR November 1995, To help enhance water quality and reduce the potential nutrient impacts
downstream utilization of the non-wetland floodplain will be used where feasible for . stormwater
treatment.

Re: Pulte Homes at Ballan ne - ± 80 Acre Site, Charlotte, Mecklenburg County. North Carolina -
Nationwide Permit #26
Dear Sirs:
On behalf of my clients, Mr. Jim Praechtl of Pulte Home Corporation, I am providing you with the
additional information and explanation you requested concerning the proposed mixed use development.
Attached please find :
USGS Map - 2000' scale
2. USGS Map - 500' scale
3. Site Plan showing approximate location of wetland impacts in 1994. This area was review by me
and Mike Parker in the field on June 1, 1994. Based on this preliminary review, these wetlands were
found to be degraded (rutted; Hurricane Hugo impacts; overgrowth of rose and ligustrum) and high in the
drainage area. At that time. it was determined that the water quality functions of this wetland area could
be mitigated with the development of a stormwater management facility with a littoral zone. Mike Parker
is likely to remember this meeting due a remark that a contractor on the site made to us regarding his
prediction of our political affiliations ("are you with Clinton").
The impacts to this wetland area were mitigated for through the creation of wetlands along McAlpine
Creek tributary. This created wetland is fully functioning and provides water storage, bank stabilization,
pollution removal, and is a viable aquatic resource. Also, all commercial projects throughout Ballantyne
have strictly adhered to a stormwater management plan which includes several wet detention basins. A
minimum 25' buffer was also implemented adjacent to preserved streams and wetlands.
Proposed Wetland and Stream Impacts
The purpose of the stream and wetland impacts is to create a stormwater storage and treatment facility for
the project as well as an amenity. Steep topographic conditions makes avoidance of the this area not
practicable. The riffle pool complex stream will not be impacted by the project and will be protected by a
50' buffer on the project side of the stream.

Minimization and Proposed Compensatory Mitigation
A mitigation plan is proposed for a "no net loss" of wetland and stream habitat, value, and function to the
extent feasible on this site. The proposed wetlands will be created to provide water storage, bank
stabilization, pollutant removal, and aquatic resource values as described in the Fourth Version -
Guidance for Rating Values of Wetlands in North Carolina. Impacts to important streams by grading,
fill, and culverting to important streams does not exceed ISO lf. Mitigation is provided for wetland
impacts.
Mr. John Dorney, Mr. Samar Bou-Ghazale
Page 3, May 9, 2000
A 50 f complex as e
plans
Wetland Mitigation includes approxim tely ±0.75 ]acres of wet nds will be created in conjunction with
the dry and wet detention basins. As described in the application the wetland atal is to develop areas of headwater wetlands
in various forms which are saturated within the root zone or inundated for a significant portion of the
growing season. The zones will be based on the expected saturation and inundation of the particular zones
and tolerances and include Bottomland Hardwoods, Scrub/Shrub, Emergent, and Aquatic Zones.
STORMWA TER MANAGEMENT PLAN
A Stormwater Management Plan will be designed and implemented for the project to meet the 401 Water
Quality Certification requirements. Stormwater management becomes necessary when increasing the
impervious area within an existing natural area. The planners will utilize information and guidelines
provided by the North Carolina Department of Environment and Natural Resources Water Quality Section
in developing this stormwater wetland. Wet detention basins shall be the primary treatment system for
stormwater runoff from paved surfaces and landscaping on commercial, office, business, and institutional
parcels. The wet detention basins will be designed to attenuate the first inch of rainfall over a 24 hour
period. Water will be released over a 2 to 5 day period. Discharge velocity of will be less than five cfs
from the end of the dissipation device. A littoral zone/forebay will be incorporated into the design of the
ponds to encourage additional nutrient removal. The planners will utilize information and guidelines
provided by the North Carolina Department of Environment, Health, and Natural Resources in developing
the design of wet detention basins using the Table 1.1 in the Stormwater Best Management Practices
NCDENR November, 1995, To help enhance water quality and reduce the potential nutrient impacts
downstream utilization of the non-wetland floodplain will be used where feasible for stormwater
treatment.
Please contact me if you have any questions or require additional explanation. Thank you for your

CERTIFIED MAIL-RETURN RECEIPT REQUESTED
Pulte Home Corp
7422 Carmel Executive Park, Ste. 300
Charlotte, NC 28226
Dear Mr. Praechtl:
The Division of Water Quality has reviewed your plans for the discharge of fill material into 0,94
acres of wetlands and 1,790 linear feet of streams located at Pulte Homes at Ballantyne in Mecklenburg
County for a commercial and residential development as described in your application dated March 3, 2000.
Insufficient evidence is present in our files to conclude that your project must be built as planned in waters
and/or wetlands in accordance with 15A NCAC 2H 0506. Therefore, unless modifications of the proposal
are made as described below, we will have to move toward denial of your 401 Certification as required by
I SA NCAC 2H.0507(e) and will place this project on hold as incomplete until we receive this additional
information, we are requesting (by copy of this letter) that the U.S. Army Corps of Engineers place your
project. on administrative hold.
This project will require compensatory mitigation as described in 15A NCAC 2H .0506(h). Your
mitigation proposal is insufficient because:
1. It is not clear what acreage of wetlands were previously impacted for earlier phases of
this project.
2. The distances that the wetlands you proposed from the nearest "blue line" on the 1:24,000
USGS topographic map. The later information is needed to determine the required
mitigation ratio.
Please respond within three weeks of the date of this letter by sending a copy of this information to
me and to the Mr. Samar Bou-Ghazale, Mooresville Regional Office at [phone]. If we do not hear
from you in three weeks, we will assume that you no longer want to pursue this project and we will consider
the project as withdrawn. I can be reached at 919-733-9646 if you have any questions.

APPROVAL of 401 Water Quality Certification and ADDITIONAL CONDITIONS
7422 Carmel Executive Park
Suite 300
Charlotte, NC 28226
Dear Mr. Praechtl:
You have our approval, in accordance with the attached conditions and those listed below, to place fill material in an additional 0.54
acres of wetlands (total of 0.93 acres of wetland fill) and 990 linear feet of streams for the purpose of constructing a commercial/residential
development at Pulte Homes at Ballantyne as described in your application dated March 3, 2000 and revised on May 9, 2000. After reviewing
your application, we have decided that this till is covered by General Water Quality Certification Numbers 14 & 24. These certifications allow
you to use Nationwide Permit Number 3103 and 3108 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.
I . Deed notifications or similar mechanisms shall be placed on all remaining jurisdictional wetlands and streams 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 condition is that a final, written stormwater management plan shall be approved by this Office before the impacts specified
in this Certification occur. The stormwater management plan must include plans and specifications for stormwater management facilities
designed to remove 85% TSS according to the most recent version of the NC DENR Stormwater Best Management Practicer Manual.
Also, before any permanent building is occupied at the subject site, the facilities, as approved by this Office, shall be constructed and
operational, and the stormwater management plan, as approved by this Office, shall be implemented.
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 or the North Carolina
General Statutes to the Office of Administrative Hearings. P.O. Box 27447, Raleigh, N.C. 276 1 1-7447. 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 Dorney at 919-733-9646.

Re: Mallard Creek Church Road Propea - ± 80 Acre Sit e. Charlotte. Mecklenburg County. North
Carolina - Nationwide Permit #26
Dear Sirs
On behalf of my clients, Mr. Jim Praechtl of Pulte Home Corporation, I am providing you with the following
information concerning the proposed mixed use development for your consideration. The project site is
located on approximately 80 acres in rapidly developing northeast Mecklenburg County, in the vicinity of the
University of North Carolina at Charlotte and University Research Park. Current land use in the vicinity
consist of developing single family, commercial, multi-family sites and other developments. There are
approximately 1.68 acres of jurisdictional surface waters, including over 4,320 linear feet of stream channel.
Approximately 3,670 if of stream channel have been determined important and approximately 650 If have
been deterriiined unimportant. In order to balance the site's economic viability with its environmental value
and permitability, the developer has minimized impacts to streams and wetland and has proposed stream and
wetland mitigation as required for unavoidable impacts. The preserved and created wetlands and streams
will be protected by restrictive covenants, deed restrictions, or similar mechanisms as required. The
hydrology to the existing wetlands and streams will be maintained and enhanced by utilizing the
stormdrainage system which will increase their water storage, pollution removal, bank stabilization, and
aquatic life value. A Stormwater Management Plan will also be implemented for portions of the project that
consist of Commercial, Office, Corporate, and Business land uses. Stormwater management facilities will
include stormwater ponds. Wetlands impacts will be mitigated in conjunction with the required dry and wet
detention basins.
SUMMARY OF WATERS OF THE U.S.
THODOLOGY
Preliminary identification and delineation of the Jurisdictional Waters on the site were determined according
to the Corps of Engineers Wetland Delineation Manual, Technical Report Y-87-1, 1987, with Appendices.
Preliminary data gathering included review and interpretation of topographic maps; USDA Soil
Conservation Survey; aerial photographs, and preliminary site visits to selected areas. Then the Routine
On-Site Determination Method was utilized to determine the upper boundary of the wetlands. In order to

Page 2, February 29, 2000
make a positive wetland determination indicators of hydrophytic vegetation, hydric soil, and wetland
hydrology.
The wetland areas are in various stages of succession ranging from emergent to scrub/shrub, to early
bottomland hardwood forest. The wetlands have formed in perched water table conditions, in flat to nearly
level areas, along intermittent tributaries, and depressions over an extremely dense clayey subsoil layer often
associated with inclusions in Helena and Monocan (Mo) soils. These soils may have inclusions of hydric soils
according to the Natural Resource Conservation Service, Technical Guide-Section H-A-2, June 1991. A
depression swamp and hardpan forest areas was also identified on the site. These wetlands are considered
valuable for water quality and habitat, especially for amphibians.
The hydrological features include intermittent to perennial tributaries of varied widths and depths and
adjacent wetlands. The stream are unnamed tributaries of McAlpine Creek which flows to the Sugar Creek
in the Catawba River Basin. The water classification is "C" : aquatic life propagation and survival, fishing,
wildlife, secondary recreation, and agriculture. All the surface waters and wetlands on this site are above the
headwaters line.
Vegetation
A majority of the site is in various stages of succession from formerly farmed areas. A large portion of the
site is heavily disturbed.
Vegetation in wetland and riparian areas are dominated by Facultative, Facultative Wet, and Obligate
Vegetation and include black willow, green ash, willow oak, red maple, sweet gum, alder, silky dogwood,
greenbriar, poison ivy, multiflora rose, and others. 'Herbaceous plants include sedges, needle rush,
jewel-weed, and other typical wetland species.
Hydrophytic Vegetation has been identified according to the National List of Plant Species That Occur in
Wetlands: Southeast (Region-4 U.S. Department of the Interior, Fish and Wildlife Service.

WETLANDS PERMITTING AND MITIGATION
Preliminary planning for the overall project involved site analysis and consideration of environmental,
economic and regulatory issues. Topography, natural features and systems, circulation, site organization,,
open space, development requirements, and environmental issues were considerations in designing the
overall plan. Except for temporary construction and development impacts, we believe that the proposed
project will not cause significant impacts to the ecological functions or values of Jurisdictional Waters of the
U. S.
Avoidance. Minimization, and Mitigation
Due to the economic, engineering, and spatial requirements of a development of this magnitude, large
contiguous areas must be graded for building pads and parking. However the following avoidance and
minimization efforts and Best Management Practices will be employed to minimize impacts to Jurisdictional
Waters. These will include:
a) Barricades to define construction limits to sensitive sites and to protect trees
b) Preconstruction meetings
c) Vehicular access will be restricted to specific areas to avoid disturbance to adjacent wetlands and
natural areas to be preserved.
d) Methods to prevent short term impacts will be inspected regularly and maintained during
construction of the project.
e) Project construction will strictly adhere to an approved Sedimentation and Erosion Control Plan.
Best Management Practices will include utilizing siltation trapping ponds and other erosion control
structures where appropriate. Impacts from hazardous materials and other toxins to fish and
aquatic life such as fuels will be avoided by not permitting staging areas to be located near surface
waters.
f) As required by the 401 Water Quality Certification'zonditions, measuresswill be taken to prevent
"live" or fresh concrete from coming into contact with waters until the concrete has hardened.

mitigation plan is proposed for a "no net loss" of wetland and stream habitat, value, and function to
tent feasible on this site. . The proposed wetlands will be created to provide water storage, b
ibilization, pollutant removal, and aquatic resource values as described in the Fourth Version - Guidf
r Rating Values of Wetlands in North Carolina. Impacts to important streams by grading, fill,
lverdng to important streams does not exceed ]SOY' . Mitigation is provided for wetland impacts.
wet detention basins.
±0.75 acres of wetlands will be created in conjunction with the
The purpose of the wetland mitigation proposal is to develop areas of headwater wetlands in various forms
which are saturated within the root zone or inundated for a significant portion of the growing season. The
zones will be based on the expected saturation and inundation of the particular zones and tolerances and
include Bottomland Hardwoods, Scrub/Shrub, Emergent, and Aquatic Zones. The hydrology will be
supported by stormwater runoff, overland flow, and captured rainfall. This proposed wetland mitigation site
is expected to be inundated and saturated especially during the winter, early spring, and major rain events.
The following hydrological zones are expected to occur within the wetland mitigation areas:
- Semipermanently to permanently: area is inundated or saturated from 75% to 100% of the
growing season.
- Regularly: area is inundated or saturated from 25% to 75% of the growing, season.
- Seasonally: area is inundated or saturated from 12.5% to 25% of the growing season.
- Irregularly: area is inundated or saturated from 5% to 12.5% of the growing season.
- Vegetation - The majority of the species utilized will include Obligate (OBL) and Facultative Wet
(FACW) vegetation. To a lesser extent Facultative (FAC) species known to be prevalent in wetlands in the
local area will be utilized. Vegetation species that provide benefits to wildlife habitat will be incorporated
into the mix of species utilized.
Data will be collected from field observations in order to record the development of wetland
hydrology, hydric soils, and hydrophytic vegetation as described in the 1987 U.S. Army Corps of Engineers
Wetland Delineation Manual criteria.
Normal hydrology will be considered the percent of time which the upper 12" exhibits inundation or
saturation. If the amount of precipitation is unusually high or low than the wetland hydrology success criteria
will be 5% to 12.5% of the growing season. Hydrology is expected to be supported by runoff from the
project site and from the remaining watershed off-site. Also, the proposed mitigation and stormwater
treatment area is easily accessible for monitoring and could be utilized for education related purposes.
Soils shall be topsoil or stockpiled suitable wetland soil and have a minimum of 40% organic
content. Soils shall be spread and compacted to 90%. Eighteen inches to two feet of topsoil and shall be
spread and adequately compacted as a planting medium throughout the mitigation cell. Note that
excavation in the proposed wetland areas should be below finish grade prior to placement of topsoil.
Before placement of the topsoil, the subgrade and hydrological conditions must be assessed.
Mr. Steve Chapin - USACE, Mr. John R. Dorney, Mr. Mike Parker - NCDWQ
Page 5, February 29, 2000
Manipulation of soil depth will be required to create micro-topography within mitigation cell. Field
modifications may be required based on actual site conditions.
The wetland mitigation areas shall be stabilized with grasses or other herbaceous materials for at
least one growing season to observe hydrological, soil development and vegetation which is volunteering.
Adjustments may then be made as required to the water control structures, spillways, and grading as
required. Installation of the wetland materials should not take place until the site's hydrology has stabilized
and discharge structures have been adjusted as necessary.
The entire mitigation cell shall be completely impounded to fully saturate soils prior to adjusting
discharge structures and establishing hydrological zones.
Watering to maintain moist soils throughout all elevations may be necessary during the first
growing season.
Vegetation
Planting includes of a diversity of saturation tolerant tree species which are also high in wildlife value. The
planting plan will also encourage a diverse canopy and mid-story vegetation. The primary criteria upon
which plant selection is based is the duration of soil saturation. Soil saturation is expected to occur at a rate
similar to adjacent wetland and / or riparian areas and is expected to be for a minimum of 12 consecutive
days and a maximum of 52 consecutive days under normal circumstances during the early part of growing
season. Tree species tolerant of these hydrological conditions will be specified in the mitigation areas.
Forested mitigation sites will be planted at an initial density of approximately 500 trees woody stems per
acre by utilizing a combination of bare root seedlings and/or larger vegetation. Scrub/shrub mitigation sites
will be planted at an initial density of approximately 1000 woody stems per acre by utilizing a combination of
bare root seedlings and/or larger vegetation. In addition to woody species, herbaceous-,plants will be will be
planted in an organized pattern or groupings of a similar hydrophytic zone. These zones adjacent to surface
waters improve water quality by filtering runoff, trapping sediment, absorbing nutrients, and provide wildlife
habitat and a food source for aquatic organisms, amphibians, birds and other wildlife.
Vegetation will be selected from the following general lists.
Scrub/Shrub Zone
Alnus spp.
Cornusamomum
Sambucus canadensis
Itea virginica
Ilex decidua
Viburnum dentatum
Cephalanthus occidentalis
Lindera benzoin
Others that are approved
Bottomland Hardwood - Forested Zone

Zone 1- Wetland areas in temporarily saturated soils or subject to occasional and brief inundation
Agrostis alba (Red Top) Polygonum spp.(Smartweed) Carex species (Sedge)
Juncus effusus (Soft Rush) Eleocharis spp.(Spikerush) Others as specified
Mr. Steve Chapin - USACE, Mr. John R. Dorney, Mr. Mike Parker - NCDWQ
Page 6, February 29, 2000
Zone 2 - Wetland areas prone to persistent ooding or pmding
Moist to I Foot of Water
Three Square Bulrush Creeping Spike Rush Soft Rush
Sedge species Lizard Tail Others
Shallow Water Plants
Sweet Flag Arrow-Arum Duck Potato
Pickerel Weed Others
Other plants may be selected from Table 11.2 in Stormwater Best Management Practices, November 1995.
Monitoring
Monitoring of wetland creation activities will be performed to evaluate the mitigation site relative to the
success criteria. Annual reports will be prepared which summarizes the data collected in the field and notes
trends. Photographs at fixed stations will be taken to document the trends and changes occurring at the sites.
These reports will be furnished to the Corps of Engineers and the North Carolina Division of Water Quality.
Vegetation Monitoring
Four sample plots will be identified. The plots will monitor at least 30' radius to record the number
and species of each surviving woody stem and the percent aerial cover of the three most dominant species.
Within the 30' radius area a 10' radius area will be established to record the three dominant herbaceous
species. %
Mitigation areas will be monitored bi-annually during March/April and August/September to
measure survival rate, species diversity, growth.
Identify upland species and invasive species to be removed such as honeysuckle, blackberry, rose,
poison ivy, kudzu, ligustrum, etc.
Vegetation Success Criteria
At least 320 woody stems per acre are surviving. If this criteria is not met, the area is not
considered to be successful and maintenance will need to be performed on the area in order to provide the
required quantify. A five year monitoring period will be conducted for forested plant communities.
A minimum 75% cover after five years is required for herbaceous plant cover.
Hydrology Monitoring
Monitoring wells will be designed and placed in accordance with the specifications in U.S. Corps of
Engineers, Installing Monitoring Wells / piezometers in Wetlands (WRP Technical Note HY-lA-3.1, August
1993). Monitoring Wells will be set to a depth 24 inches below the surface soil, if required. These
monitoring wells will be imbedded within vegetation sampling plots to provide representative coverage
within each of the ecosystem types. Hydrological sampling will be performed throughout the growing season
at intervals necessary to satisfy the hydrology success criteria. It will be observed on a monthly or as needed
basis for at least the first year in order to establish a record of the hydrology throughout the year.
Mr. Steve Chapin - USACE, Mr. John R. Domey, Mr. Mike Parker NCDWQ
Page 7, February 29, 2000
Hydrological Success Criteria
Saturation or inundation for at least 12.5% of the growing season at lower landscape positions during
average climatic conditions is the target hydrological characteristic. Upper landscape areas may exhibit
inundation and/or saturation between 5% and 12.5% of the growing season. If wetland parameters are
marginal, consultation with USACE personnel will be conducted to determine the jurisdictional extent in
transitional areas. The data collected during the monitoring period will be utilized to evaluate the success of
the mitigation areas. The success criteria will be as follows:
Soil saturation within 12 inches of the surface for a minimum of approximately 12 consecutive days
during the early part of the growing season.
Observed evidence of inundation or saturation within the root zone for 5% to 12.5% of the
growing season.
Establish at least one hydrology indicator per the 1987 USACE Wetland Delineation Manual in the
sample plot or match adjacent riparian habitat surroundings.
Establishment of at least one hydric soil characteristic.
These Vegetative, Soil, and Hydrological Characteristics must be met to determine success of the wetland
mitigation. If the mitigation is determined to be unsuccessful the following one or more of the following
contingency plans will be implemented.
1) Selected re-installation of vegetation, thinning, maintenance, and/or acceptance
2) Extended monitoring periods
3) Hydrological modifications or manipulation and/or
4) Off-site mitigation sites and/or.
5) Acceptable alternative form of mitigation.
Report Submittal
An "as-built" plan drawing of the area, including initial species compositions by the community type, and
sample plot locations will be provided after completion of planting. A review of the actual design, densities,
and quantities will also be included and will be provided within 90 days of completion of planting. Submitted
reports will document the sample plot locations, along with photographs which illustrate site conditions.
Monitoring Reports will include:
1) species and quantity of each surviving woody stem
2) Estimated percent aerial cover of the three dominant species
3) Representative photographs
4) Depth of water table during early part of the growing season
5) Hydric soil observations and other hydrological characteristics.
Field data will be recorded on a monitoring data form and submitted along with representative photographs
in a annual monitoring report. This will be submitted to the USACE and the NCDWQ. After the fifth year of
monitoring, a summary report and as-builts will be furnished for review and discussion regarding compliance
of the project with conditions of the permit and to determine the need for future monitoring or
modifications.
Mr. Steve Chapin - USACE, Mr. John R. Dorney, Mr. Mike Parker - NCDWQ
Page 8, February 29, 2000
The mitigation areas will be monitored bi-annually to identify maintenance requirements that will encourage
the successful development of the wetland mitigation sites and function of the stormwater quality facilities.
This will include the following:
a) Vegetation management
b) Semi-annual inspections
C). Debris check after storm events
d) Establishment of a benchmark for sediment removal with specific elevations
e) Designation of a responsible party
1) Vegetation Management
The presence of invasive species that will effect the positive development of the wetlands shall be identified
at the monitoring periods and will be removed by the representative of the responsible party. These species
are likely to include honeysuckle, blackberry, rose, poison ivy, kudzu, eleagnus, ligustrum, cattails, etc.
Vegetation may be removed by physical or by the use of an approved herbicide such as "Round-up",
"Rodeo" or equivalent.
2) Inspections
Mitigation areas will be monitored bi-annually during March/April and August/September and/or storm
events to determine the need for maintenance such as the removal of debris and/or repairs to the mitigation
site such as those caused by erosion.
3) As-builts - Benchmark for Sediment Removal
Field adjustment is expected during the construction of the restoration and stormwater quality basins. An
"as-built" plan drawing of the area will include a. benchmark for sediment removal will also be established for
the storm water quality wet detention basins. Removed sediment will be transported to an upland site and -'y
stabilized. ln'some cases it may be appropriate to utilize the. appropriate sediment such as washed top$pil tq._
enhance or modify the development of the wetland areas. This will be determined on a case by case hasisand
will be included in the monitoring report. The following requirements have been developed for the ponds
and stormwater wetlands to be signed by the owner.
Protection from Future Development
Upon completion of construction of the wetland sites as - built drawings will be prepared. The survey will
include:
- boundary of each area
- finish grades
- location of monitoring wells, if necessary and sample plots
- drainage control features
- Other significant information, as required

STORMWA TER MANAGEMENT PLAN
A Stormwater Management Plan will be designed and implemented for the project to meet the 401 Water
Quality Certification requirements. Stormwater management becomes necessary when increasing the
impervious area within an existing natural area. The planners will utilize information and guidelines provided
by the North Carolina Department of Environment and Natural Resources Water Quality Section in
developing this stormwater wetland. Wet detention basins shall be the primary treatment system for
stormwater runoff from paved surfaces and landscaping on commercial, office, business, and institutional
parcels. The wet detention basins will be designed to attenuate the first inch of rainfall over a 24 hour period.
Water will be released over a 2 to 5 day period. Discharge velocity of will be less than five cfs from the end
of the dissipation device. A littoral zone/forebay will be incorporated into the design of the ponds to
encourage additional nutrient removal. The planners will utilize information and guidelines provided by the
North Carolina Department of Environment, Health, and Natural Resources in developing the design of wet
detention basins using the Table 1 1 in the Stormwater Best Management Practices- NCDENR November
1995. To help enhance water quality and reduce the potential nutrient impacts downstream utilization of the
non-wetland floodplain will be used where feasible for stormwater treatment.
THREATENED AND ENDANGERED SPECIES
Federally listed plant and animal species with endangered or threatened status are protected under the
Endangered Species Act of 1973. The US Fish and Wildlife Service has identified two endangered species -
Schweinitz's sunflower (Helianthus schweinitzii), and the Carolina heelsplitter (Lasmigona decorata).
Schweinitz's sunflower thrives in full sun characteristic of successional fields, margins, and forested
openings. A review of USGS (Weddington Quad) Maps at the Natural Heritage Program at NCDENR in
Raleigh did not indicate any endangered species previously identified on the site. Since Schweinitz's
sunflower is known to occur in this area of the county, I was accompanied by James F. Matthews, Ph.D.
(UNCC) of Habitat Assessment and Restoration Program during the site evaluation process. Aecording to
his survey, Schweinitz's sunflower was not identified. The presence for other federally and state listed
species were also investigated. Several hundred specimens of Heller's Trefoil (Lotus helleri), a Federal
Candidate #2 species were present. Prior to development of the site, the Ballantyne Development
Corporation made this plant material on the site available for potential recovery. This effort was coordinated
by James F. Matthews according to methodology approved by the U.S. Fish and Wildlife Service.
The Carolina heelsplitter is a freshwater mussel which prefers shaded areas either in a ponded portion of a
small stream or in runs along steep banks with moderate current. Primary habitat are waters less than three
feet deep with a soft mud, muddy sand, or shady gravelly substrate. It is normally restricted to protected
silted areas or under banks especially associated with obstructions such as stumps or fallen trees. Its current
distribution according to the US Fish and Wildlife Service is limited to portions of two streams -- Goose
Creek and Waxhaw Creek -- and a small river originating from rural areas in Union County. Therefore it is
not expected to occur on this site.
rote ea 5neci
The Carolina Darter (Etheostoma collis) is a fish that inhabits small streams such as those found in the
project area. This species has a federal status of Proposed Special Concern and a state status of Special
Concern. The species prefers small clear streams of less than 15' width with moderate to swift current and a
sand/gravel benthic composition. It apparently tolerates a wide range of water quality conditions and
vegetation types adjacent to the streams and appears resistant to pollution. (E. Menhinick). There are no
streams on this site and therefore this species is not expected to occur on this site. Drainage from this site
Mr. Steve Chapin - USACE, Mr. John R. Dorney, Mr. Mike Parker - NCDWQ
Page 10, February 29, 2000
eventually will eventually flow to McAlpine Creek tributaries where this species may occur. Therefore, strict
adherence to an approved erosion and sedimentation control plan will be maintained during the construction
period in order to control degradation of water quality.
CULTURAL RESOURCES
Based on the findings of the Archaeological Survey for the Proposed Ballantyne Project (Ballantyne
Development Corporation), conducted by Archaeological Research Consultants, June, 1994, no historic or
prehistoric sites appear to be in the project area eligible for the National Register of Historic Places.
According to the report, no additional archaeological surveying, testing, or data recovery on the Ballantyne
Development Corporation of the Ballantyne Project was recommended. Based on the survey, no sites were
found that are eligible for listing in the National Historic Register. This report was forwarded to the SHPO
during the previous application reviews and concurrence was received.
PROTECTION FROM FUTURE DEVELOPMENT
The preserved wetlands and streams will be protected from future impacts by the applicant or by a group
designated by the applicant for this purpose. As required, development of these areas will be deed restricted
in accordance with restrictive covenants, or similar mechanisms which will be developed for approval by the
USACE and/or NCDWQ.
CONCLUSION
Based on the value of the jurisdictional waters and wetlands on this site, the developer through sensitive site
planning has chosen to balance the site's economic viability with its environmental value and permitability.
The goal of the Site Plan and Mitigation Plan is to help balance the environmental consequences of this
development by creating beneficial wetland or riparian habitat and enhancing and preserving the
Jurisdictional Waters of the U.S. remaining on the site. The undisturbed wetland areas and the mitigation
sites will be preserved by the applicant or by a group designated by the owner for this purpose. They will be
managed as a wetland system of high value.
