Dear Sirs:
You have our approval to place fill material in 0.60 acres of wetlands or waters for the purpose of
developing a residential and commercial development at Franklin Square at US 29 and 74, as you described in
your application dated 30 August 1996. After reviewing your application, we have decided that this fill is
covered by General Water Quality Certification Number 2671. This certification allows you to use
Nationwide Permit Number 26 when it is issued by the Corps of Engineers.
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 this approval to be valid, you must follow the conditions listed in the attached certification
and any additional conditions listed below. Deed restrictions shall be added to all remaining wetlands to
prevent future fill. Additional written approval from DWQ is required for stormwater management of the
commercial development before wetland filling occurs. Wetlands shall be flagged prior to grading to reduce
inadvertent impact. 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.
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

Re: Franklin Square - Request for NWP 26 Approximate 44 Acre Tract at Highway 29 & 74
Franklin Boulevard. Gastonia. North Carolina
Dear Sirs:
On behalf of my client, Mr. Steve Brumm of AAC Services, Inc, I am requesting your review of the
enclosed plans and information concerning the development plans for your consideration and approval under
Nationwide Permit 926.
Background
The proposed use of the site is a regional commercial development in the rapidly growing corridor between
Charlotte and Gastonia. After determining that this site was of sufficient size and met preliminary economic
requirements, the developer began feasibility planning. During the "due diligence" period I was asked to
conduct a wetland delineation. The wetland areas were delineated in April and May, 1996 then verified by
Steve Chapin of the USACE on May 21, 1996. The site is currently developed and is occupied by Public
Service Company ofNorth Carolina which will relocate.
Summary of Jurisdictional Waters of the U.S.
11 Wetland Hydrology
Wetland hydrology is provided by a surface runoff, overbank flooding, seeps, and springs over a clayey
subsoil. The primary tributary is Ziegler's Branch which is a tributary of Duhart's Creek. Duhares Creek is a
tributary of the Catawba River.
21 -H-yd=bZic Vegetation
Vegetation in wetland areas and along tributaries. is dominated by Facultative Wet, and Obligate Vegetation
and includes alder, green ash, boxelder, willow and others in areas that are seasonally flooded. Shrub/scrub
layer was dominated by silky dogwood and spicebush. Herbaceous plants include sedges, soft rush,
jewelweed and other typical herbaceous species. In areas subject to temporary flooding the vegetation
included facultative vegetation such as red maple, sweetgtim, cottonwood, poison ivy, and smilax.

Ligustrum, blackberry, and honeysuckle were extremely dense especially in non-wetland floodplain areas and
"choking out" natural succession. In many portions of the floodplain the vegetation is nearly a mono-culture
of ligustrum.
3) H i . Soil
Hydric soils caused by saturation, ponding, and flooding and occur as inclusions within Chewacla soil types
on this site. According to Soil Conservation Service, Technical Guide-Section II-A-2, June 1991, Ch
(Chewacla) soils are listed as Map Units with inclusions of Hydric Soils in Gaston County. Other hydric soils
created by hydrological conditions such as flooding and a high or perched water table were found.

Results of Preliminary Discussions with ACE
Wetland Area "B", "C", and "D" have high value and impacts to these areas should be avoided and
minimized to the extent feasible. It was noted that several floodplain areas in the vicinity of wetland area
"B" and "C" were previously impacted by siltation from previous development on the site and the silt fence
was not removed. Wetland Area "D" is fed by springs and surface runoff. Maintaining the hydrology to these
wetlands should be an important planning consideration.
Results ofPreliminary Wetland Evaluation/N DWQ Guidelines
The preliminary site plan, avoidance and minimization planning, and wetland evaluation were reviewed in
Mooresville and on-site with Mr. Mike Parker of the NCDWQ on June 25, 1996. The results of the
evaluation were that Area "B", "C", and "D" had very high value regarding water storage, pollution removal,
bank stabilization, and aquatic life utilizing Guidance for Rating the Values of Wetlands in North Carolina -
Fourth Version and impacts to these areas should be avoided and minimized to the fullest practical extent.
PROPOSED A T
Impacts to Jurisdictional Waters on this site have been avoided and/or minimized to the extent feasible.
Impacts to wetlands are limited to the following:
1) "A"- Bed and Bank Tributary (PFO1 A) = ±0.340 acre
2) "B"- Headwater Forest (PFO1C, PSS1C) =± 0.002 acre
3) "C"- Headwater Forest (PFOIA, PSS1A) = ± 0.100 acre

7) "G"- Intermittent Trib tarv = + 0.0086 acre
Total Jurisdictional Waters Impacted = ± 0.60 acres
Mr. Steve Lund, Mr. John Dorney, Mr. Mike Parker, August 30, 1996, Page 3
PROPOSED MINIMIZATION AND MITI A----
Minimization
Several design meetings were held with Steve Brumm of AAC and Kevin Caldwell of W.K. Dickson, and
me, to review planning to avoid and minimize impacts to important wetlands on this site. The square
footage of the primary commercial center as well as at least one out-parcel were removed from the initial
project scope. Road, parking, and building layout were also modified to reduce impacts to the extent
practicable.
Plans and overall scope of project modified to extent feasible to minimize impacts to the highest
quality wetlands according to NCDWQ Guidelines. 1.17
Strong erosion control measures will be employed to minimize additional impacts to thel wetlands
from sedimentation and erosion from previous development. Construction limits will be clearly
delineated on the site to prevent unauthorized impacts.
Best Management Practices will also be employed to minimize impacts to Jurisdictional Waters. This will
include:
Siltation Barriers
Sediment Traps and Diversion Ditches
Barricades to define construction limits to sensitive sites and to protect trees
Preconstruction meetings
Other methods as appropriate
Vehicular access will be restricted to specific areas to avoid disturbance to adjacent wetlands and
natural areas to be preserved. Methods to prevent short term impacts will be inspected regularly and
maintained during construction of the project. The contractors will be held responsible for unauthorized
wetland damage not permitted according to plans and specifications. Preconstruction meetings shall be held
if necessary with representatives of the USACE and the NCDWQ.
Short term construction impacts, primarily stream sedimentation will affect aquatic habitat,
however this will be minimized to the extent practicable to promote rapid recovery. 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. Also, as required by the 401 Water Quality
Certification conditions, measures will be taken to prevent "live" or fresh concrete from coming into contact
with waters until the concrete has hardened.
- Unauthorized impacts to wetlands, if any, due to minor or temporary construction impacts will be
restored in "like kind" and would include re-establishing the contour and planting.
Hydrology to the existing wetlands will be maintained to the extent feasible. Stormwater may be
necessary to maintain the hydrology to Area"D". Water from the proposed wet detention pond as well as
surface runoff will be utilized to maintain the hydrology to Area "B" and "C".
.Proposed C Mpensatorv Mitigation
As depicted on the site plan a strong efforts were made to avoid and minimize impacts to the highest value
wetlands on the site. Therefore "no net loss" of wetland value and function apparently has been achieved.
Therefore no mitigation is proposed. Unauthorized impacts to wetlands, if any, due to minor or temporary
construction impacts will be restored in "like kind" and would include re=establishing the contour and
planting.
Mr. Steve Lund, Mr. John Dorney, Mr. Mike Parker, August 30, 1996, Page 4
STORMR?ATER MANA EMENT PLAN
A Stormwater Management Plan will be designed and implemented for the project to meet the 401 Water
Quality Certification requirements. Stormwater runoff from paved surfaces and landscaping has the potential
to degrade water quality in all types of waters. Wet detention basins shall be the primary treatment system.
Properly designed wet detention basins have been proven to be a viable solution to reduce pollution. They
are efficient in removing suspended solids and other pollutants, reducing peak runoff rates, and controlling
downstream erosion. There is also a potential aesthetic value if the pond's can be designed into the overall
plan.
Stormwater Management Plan once is
Stormwater management becomes necessary when increasing the impervious area within an existing natural
area. The impact of the increased runoff and reduction of natural filtration will be analyzed with respect to
the capacity and stability of natural channels and the presence of environmentally sensitive areas. The pie
and post-development runoff will be determined and used as the basis of stormwater management
techniques. Special consideration will be given to avoiding erosion and degradation of environmentally
sensitive areas, wetlands, and surface waters.
The Stormwater Management Plan will include:
A. Wet Detention Basins that will attenuate 1.0 inch of rainfall over a 24 hour period for high density
sites including office, commercial and business uses.
B. Utilization of wetland mitigation areas where possible to increase filtration.
C. Riser outflow structures to maintain a pool and encourage filtration.
D. Directing runoff into natural areas and wetland/biofilters to treat runoff before entering surface
waters.
E. Maintaining natural and planted areas between the developments and
Jurisdictional Waters.
F. Development of a wetland littoral shelf where feasible in shallow areas
The engineers 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.
Schedule
Grading and installation of water control structures where applicable will be conducted concurrently with
project construction and are expected to begin in the spring of 1997.
THREATENEDA N ENDAN RED PE - ,
Federally listed plant and animal species with endangered or threatened status are protected under the
Endangered Species Act of 1973. The site is currently developed and a review of USGS (Mt. Holly) Maps at
the Natural Heritage Program at NCDEHNR in Raleigh did not indicate any endangered species or sensitive
habitat on the site.
Mr. Steve Lund, Mr. John Dorney, Mr. Mike Parker, August 30, 1996, Page 5
LTURAL RE OURCE
Existing structures on the site include office buildings and maintenance and vehicular service facilities.
There are no indications of any existing historical structures on the project site or adjacent areas. The Office
of State Archaeology (OSA) and the Survey and Planning Branch (SPB) of the NC Department of Cultural
Resources - State Historic Preservation Office (SHPO) was visited in March, 1996 and again on June 11,
1996, to review existing mapping on the USGS (Mt. Holly) Quad maps, if any. The purpose of this review
was to determine if there were previously identified sites in the project area. Based on the review of the
maps at the OSA and at the SPB, no previously identified or surveyed sites are currently indicated on the
maps within the project area. r7
AQUATIC RABITAT
The aquatic systems in the project area consist of headwater wetlands and intermittent tributaries of Duhart's
Creek A variety of wildlife is supported by these systems including mammals, birds, reptiles, amphibiins,
small fish, insects, mollusks, and crustaceans. 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 downstream and protect the areas to be preserved.
Short term construction impacts, primarily stream sedimentation will affect aquatic habitat, however this will
be minimized to the extent practicable to promote rapid recovery. 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. Also, as required by the 401 Water Quality Certification conditions,
measures will be taken to prevent "live" or fresh concrete from coming into contact with waters until the
concrete has hardened.
CONCLUSION
The 44 acre development will provide continued economic benefits to this rapidly growing area of North
Carolina. The developer's initial plan utilized more land area to accomplish the spatial planning that made
the site more economically viable. However, based on the quality of the jurisdictional waters and wetlands
on this site, the developer through sensitive site planning has balanced the site's economic viability with its
environmental value and permitability.
Please contact me if you have any questions or require additional explanation. Thank you for your time and
consideration.

Dear Mr. Brumm:
Reference'is made to the survey plat dated June of 1996, submitted by
your representatives, Mr. Leonard S. Rindner and WK Dickson, for a 44.0611
acre tract located adjacent to U.S. 29, I-85, and SR 2339, near Gastonia, in
Gaston County, North Carolina. The survey plat accurately reflects the limits
of waters and wetlands on the property. Unless there is a change in the law
or our published regulations, this determination of the limits of waters and
wetlands may be relied upon for a period not to exceed 5 years from the date
of the survey plat.
Pursuant to Section 404 of the Clean Water Act, prior Department of the
Army approval is required for the discharge of dredged or fill material in
waters of the United States, including wetlands.
If you have questions, please contact Mr. Steve Chapin, Asheville Field
Office, at [phone].
Sincerely,
Robert W. Johns
Office Manager

Example Basin Design
Using the Chart: Finding the Surface Area of the Permanent Pool
The numbers in the chart represent surface area (SA) to drainage area (DA) percentages. SA= the
wet detention pond permanent pool surface aroa required to provide an expected 85% Total
Suspended Solids removal. The chart is based on the amount of impervious cover as a percentage
of the area draining to the pond and the depth of the permanent pool. Impervious percentages are
in the left band column of the chart and depths are given across the table from 3 feet to 9 feet in
one foot increments. If needed, one can interpolate to And the SA/DA ratio that is needed in a
particular case.
To determine the required permanent pool size use the following steps:
1. Calculate the percent impervious cover of the site draining to the pond
amount of impervious area / total site area
2. Determine the permanent pool depth (or select a depth for comparison purposes).
3. Go to the above chart and find the number corresponding to the impervious percentage found
above and the depth assumed. 'This numbers represents the permanent pool surface area as a
percent of the drainage area.

z-^ WATER. QUALITY PLANNING Fax:[phone]
Jun 15 '94 10:16

P.03/03
4. To determine the required surface areas of the permanent pool, take the number from the
chart divide by 100 and multiply this number by the contributing drainage area.
Example: assume a 10 acre site with 3 acres of impervious cover.
1. % impervious = 3/10 = 0.30 or 30%
2. Assume an average permanent pool depth of 4 feet
3. From the chart, with 30% impervious and a 4 foot depth, the SA/DA ratio is given
as 1.08%
4. The required surface area would then be;
(1.08 / 100) * 10 acres = 0.108 acres or 4,705 square feet
:r
Finding the volume to be controlled from the 1" storm
5. The design runoff volume (the water quality pool) to be controlled must then be held in
the pond above this pool permanent pool level. An example of finding this volume is
shown below.
Example: Again, on the same 10 acre, 30% impervious site.
Using the runoff volume calculations in the "Simple Method" as described by Schueler
(1987);
Rv=fl.05 + 0.009()
Rv = runoff coefficient = storm runoff (inches) / atom rainfall (inches)
I = Percent Impervious = Drainage area (acres) / Impervious portion of the
drainage area (acres)
In this example:
Rv = 0.05 + 0.009 (30)
Rv = 0.32 (inches 1)
For the volume that must be controlled:
Volume = 1" rainfall * 032 (inches 1) * 1/12 (feet / inches) * 10 acres
Volume = 0.267 acre feet or 11,616 fe
This volume must be drawn down over a period of two to five days.
NOTE: Other methods may be used to determine the volume of runoff from the V storm,
but care must be taken because all methods have their limitations and applications. The
method shown is used because it offers a conservative estimate of runoff volume for a broad
variety of land uses and im ervious cover percentages.

Re: Franklin Square - Request for NWP 26 Approximate 44 Acre Tract at Highway 29 & 74
Franklin Boulevard. Gastonia. North Carolina
Dear Sirs:
On behalf of my client, Mr. Steve Brumm of AAC Services, Inc, I am requesting your review of the
enclosed plans and information concerning the development plans for your consideration and approval under
Nationwide Permit #26.
Background
The proposed use of the site is a regional commercial development in the rapidly growing corridor between
Charlotte and Gastonia. After determining that this site was of sufficient size and met preliminary economic
requirements, the developer began feasibility planning. During the "due diligence" period I was asked to
conduct a wetland delineation. The wetland areas were delineated in April and May, 1996 then verified by
Steve Chapin of the USACE on May 21, 1996. The site is currently developed and is occupied by Public
Service Company of North Carolina which will relocate.
Summary of Jurisdictional Waxers of the U.S,
1) Wetland Hydrology
Wetland hydrology is provided by a surface runoff, overbank flooding, seeps, and springs over a clayey
subsoil. The primary tributary is Ziegler's Branch which is a tributary of Duhart's Creek. Duharfs Creek is a
tributary of the Catawba River.
2) Hvdrophytic Vegetation
Vegetation in wetland areas and along tributaries is dominated by Facultative Wet, and Obligate Vegetation
and includes alder, green ash, boxelder, willow and others in areas that are seasonally flooded. Shrub/scrub
layer was dominated by silky dogwood and spicebush. Herbaceous plants include sedges, soft rush,
jewelweed and other typical herbaceous species. In areas subject to temporary flooding the vegetation
included facultative vegetation such as red maple, sweetgum, cottonwood, poison ivy, and smilax. -

Ligustrum, blackberry, and honeysuckle were r m 1 dense especially in non-wetland floodplain areas and
choking out natural succession. In many portions of the floodplain the vegetation is nearly a mono-culture
of ligustrum
3) Hydric Soil
Hydric soils caused by saturation, ponding, and flooding and occur as inclusions within Chewacla soil types
on this site. According to Soil Conservation Service, Technical Guide-Section II-A-2, June 1991, Ch
(Chewacla) soils are listed as Map Units with inclusions of Hydric Soils in Gaston County. Other hydric soils
created by hydrological conditions such as flooding and a high or perched water table were found.

JURISDICTIONAL WATER AND WETLAND DE RIPTION
1) "A"- Bed and Bank Tributary (PFOIA) 0.3935 acre
2) "B"- Headwater Forest (PFOIC, PSS1C) 0.0742 acre
3) "C"- Headwater Forest (PFOlA, PSS IA) =±0.3881 acre
4) "D"- Headwater Forest (PFO1C, PFOIA) 0.2587 acre
5) "E"- Headwater Forest (PFO1 A) 0.1518 acre
6) "F"- Headwater Forest and Tributary (PSSIA) 0.0065 acre
7)_ "G"- Intermittent Tributary 0 0086 acre
Total Jurisdictional Waters = ± 1.2814 acres
Results of Preliminary Discussions with USA CE
Wetland Area "B", "C", and "D" have high value and impacts to these areas should be avoided and
minimized to the extent feasible. It was noted that several floodplain areas in the vicinity of wetland area
"B" and "C" were previously impacted by siltation from previous development on the site and the silt fence
was not removed. Wetland Area "D" is fed by springs and surface runoff. Maintaining the hydrology to these
wetlands should be an important planning consideration.
Results of Preliminary Wetland Evaluation/NCDWQ Guidelines
The preliminary site plan, avoidance and minimization planning, and wetland evaluation were reviewed in
Mooresville and on-site with Mr. Mike Parker of the NCDWQ on June 25, 1996. The results of the
evaluation were that Area "B", "C", and "D" had very high value regarding water storage, pollution removal,
bank stabilization, and aquatic life utilizing Guidance for Rating the Values of Wetlands in North Carolina -
Fourth Version and impacts to these areas should be avoided and minimized to the fullest practical extent.
PROPOSED IMPACTS
Impacts- to Jurisdictional Waters on this site have been avoided and/or minimized to the extent feasible.
Impacts to wetlands are limited to the following:
1) "A"- Bed and Bank Tributary (PFO 1 A) = ± 0.340 acre
2) "B"- Headwater Forest (PFO1C, PSS1C) =± 0.002 acre
3) "C"- Headwater Forest (PFOIA, PSS IA) = ± 0.100 acre
4) "D"- Headwater Forest (PFO 1 C, PFO 1 A) = ± 0.000 acre
5) "E"- Headwater Forest (PFOIA) = ± 0.1518 acre
6) "F"- Headwater Forest and Tributary (PSSIA) 0.0065 acre
7) "G"- Intermittent Tributary - + 0 0086 acre
Total Jurisdictional Waters Impacted = ± 0.60 acres
Mr. Steve Lund, Mr. John Dorney, Mr. Mike Parker, August 30, 1996, Page 3
PROPOSED MINIMIZATION AND MITIGATION
Minimization
Several design meetings were held with Steve Brumm of AAC and Kevin Caldwell of W.K. Dickson, and
me, to review planning to avoid and minimize impacts to important wetlands on this site. The square
footage of the primary commercial center as well as at least one out-parcel were removed from the initial
project scope. Road, parking, and building layout were also modified to reduce impacts to the extent
practicable.
Plans and overall scope of project modified to extent feasible to minimize impacts to the highest
quality wetlands according to NCDWQ Guidelines. /17
r?
Strong erosion control measures will be employed to minimize additional impacts to the wetlands
from sedimentation and erosion from previous development. Construction limits will be clearly
delineated on the site to prevent unauthorized impacts.
Best Management Practices will also be employed to minimize impacts to Jurisdictional Waters. This will
include:
Siltation Barriers
Sediment Traps and Diversion Ditches
Barricades to define construction limits to sensitive sites and to protect trees
Preconstruction meetings
Other methods as appropriate
Vehicular access will be restricted to specific areas to avoid disturbance to adjacent wetlands and
natural areas to be preserved. Methods to prevent short term impacts will be inspected regularly and
maintained during construction of the project. The contractors will be held responsible for unauthorized
wetland damage not permitted according to plans and specifications. Preconstruction meetings shall be held
if necessary with representatives of the USACE and the NCDWQ.
- Short term construction impacts, primarily stream sedimentation will affect aquatic habitat,
however this will be minimized to the extent practicable to promote rapid recovery. 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. Also, as required by the 401 Water Quality
Certification conditions, measures will be taken to prevent "live" or fresh concrete from coming into contact
with waters until the concrete has hardened.
Unauthorized impacts to wetlands, if any, due to minor or temporary construction impacts will be
restored in "like kind" and would include re-establishing the contour and planting.
Hydrology to the existing wetlands will be maintained to the extent feasible. Stormwater may be
necessary to maintain the hydrology to Area"D". Water from the proposed wet detention pond as well as
surface runoff will be utilized to maintain the hydrology to Area "B" and "C".
Proposed.Com?ensatorv Mitigation
As depicted on the site plan a strong efforts were made to avoid and minimize impacts to the highest value
wetlands on the site. Therefore "no net loss" of wetland value and function apparently has been achieved.
Therefore no mitigation is proposed. Unauthorized impacts to wetlands, if any, due to minor or temporary
construction impacts will be restored in "like kind" and would include re-establishing the contour and
planting.

Mr. Steve Lund, Mr. John Dorney, Mr. Mike Parker, August 30, 1996, Page 4
STORMWATER MANAGEMENT PLAN
A Stormwater Management Plan will be designed and implemented for the project to meet the 401 Water
Quality Certification requirements. Stormwater runoff from paved surfaces and landscaping has the potential
to degrade water quality in all types of waters. Wet detention basins shall be the primary treatment system.
Properly designed wet detention basins have been proven to be a viable solution to reduce pollution. They
are efficient in removing suspended solids and other pollutants, reducing peak runoff rates, and controlling
downstream erosion. There is also a potential aesthetic value if the pond's can be designed into the overall
plan.
Stormwater Management Plan Con-p- 67
Stormwater management becomes necessary when. increasing the impervious area within an existing natural
area. The impact of the increased runoff and reduction of natural filtration will be analyzed with respect to
the capacity and stability of natural channels and the presence of environmentally sensitive areas. The pre
and post-development runoff will be determined and used as the basis of stormwater management
techniques. Special consideration will be given to avoiding erosion and degradation of environmentally
sensitive areas, wetlands, and surface waters.
The Stormwater Management Plan will include:
A. Wet Detention Basins that will attenuate 1.0 inch of rainfall over a 24 hour period for high density
sites including office, commercial and business uses.
B. Utilization of wetland mitigation areas where possible to increase filtration.
C. Riser outflow structures to maintain a pool and encourage filtration.
D. Directing runoff into natural areas and wetland/biofilters to treat runoff before entering surface
waters.
E. Maintaining natural and planted areas between the developments and
Jurisdictional Waters.
F. Development of a wetland littoral shelf where feasible in shallow areas.
The engineers 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.
Schedule
Grading and installation of water control structures where applicable will be conducted concurrently with
project construction and are expected to begin in the spring of 1997.
THREATENED AN ENDANGERED SPECIEES
Federally listed plant and animal species with endangered or threatened status are protected under the
Endangered Species Act of 1973. The site is currently developed and a review of USGS (Mt. Holly) Maps at
the Natural Heritage Program at NCDEHNR in Raleigh did not indicate any endangered species or sensitive
habitat on the site.
w
Mr. Steve Lund, Mr. John Domey, Mr. Mike Parker, August 30, 1996, Page 5
CULTURAL RESOURCES
Existing structures on the site include office buildings and maintenance and vehicular service facilities.
There are no indications of any existing historical structures on the project site or adjacent areas. The Office
of State Archaeology (OSA) and the Survey and Planning Branch (SPB) of the NC Department of Cultural
Resources - State Historic Preservation Office (SHPO) was visited in March, 1996 and again on June 11,
1996, to review existing mapping on the USGS (Mt. Holly) Quad maps, if any. The purpose of this review
was to determine if there were previously identified sites in the project area. Based on the review of the
maps at the OSA and at the SPB, no previously identified or surveyed sites are currently indicat7ed on the
maps within the project area. r
AQUATIC HABITAT
The aquatic systems in the project area consist of headwater wetlands and intermittent tributaries of Duhart's
Creek A variety of wildlife is supported by these systems including mammals, birds, reptiles, amphibians,
small fish, insects, mollusks, and crustaceans. 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 downstream and protect the areas to be preserved.
Short term construction impacts, primarily stream sedimentation will affect aquatic habitat, however this will
be minimized to the extent practicable to promote rapid recovery. 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. Also, as required by the 401 Water Quality Certification conditions,
measures will be taken to prevent "live" or fresh concrete from coming into contact with waters until the
concrete has hardened.
CONCLUSION
The 44 acre development will provide continued economic benefits to this rapidly growing area of North
Carolina. The developer's initial plan utilized more land area to accomplish the spatial planning that made
the site more economically viable. However, based on the quality of the jurisdictional waters and wetlands
on this site, the developer through sensitive site planning has balanced the site's economic viability with its
environmental value and permitability.
Please contact me if you have any questions or require additional explanation. Thank you for your time and
consideration.

Example Basin Design
Using the Chart: Finding the dace Area of the Permanent Pool
The numbers in the chart represent stuface area (SA) to drainage area (DA) percentages. SA= the
wet detention pond permanent pool surface area required to provide an expected 85% Total
Suspended Solids removal. The chart is based on the amount of impervious cover as a percentage
of the area draining to the pond and the depth of the permanent pool. Impervious percentages are
In the left hand column of the chart and depths are given across the table from 3 feet to 9 feet in
one foot increments. If needed, one can interpolate to find the SA/DA ratio that is needed in a
particular case.
To determine the required permanent pool size use the following steps:
1. Calculate the percent impervious cover of the site draining to the pond
amount of impervious area / total site area
2. Determine the permanent pool depth (or select a depth for comparison purposes).
3. Go to the above chart and find the number corresponding to the impervious percentage found
above and the depth assumed. This numbers represents the permanent pool surface area as a
percent of the drainage area

wnj"r. UUHLL.i ?-- -- -
r i?

4. To determine the required surface areas of the permanent pool, take the number from the
chart divide by 100 and multiply this number by the contributing drainage area.
Example: assume a 10 acre site with 3 acres of impervious cover.
1. % impervious = 3110 = 0.30 or 30%
2. Assume an average permanent pool depth of 4 feet
3. From the chart, with 30% impervious and a 4 foot depth, the SA/DA ratio is given
as 1.08%
4. The required surface area would then be;
(1.08 / 100) * 10 acres = 0.108 acres or 4,705 square feet
ry
Finding the volume to be controlled from the 1" storm
5. The design runoff volume (the water quality. pool) to be controlled must then be held in
the pond above this pool permanent pool level. An example of finding this volume is
shown below.
Example: Again. on the same 10 acre, 30% impervious site.
Using the runoff volume calculations in the "Simple Method" as described by Schueler
(1987);
Rv=0.05 + 0.009(1)
Rv = runoff coefficient = stoan runoff (inches) / storm rainfall (inches)
I = Percent Impervious = Drainage area (acres) / Impervious portion of the
drainage area (acres)
In this example:
Rv = 0.05 + 0.009 (30)
Rv = 0.32 (inches 1)
For the volume that must be controlled:
Volume = 1" rainfall * 032 (inches /) * 1/12 (feet / inches) * 10 acres
Volume = 0.267 acre feet or 11,616 fe
This volume must be drawn down over a period of two to five days.

NOTE: Other methods may be used to determine the volume of runoff from the 1" storm,
but care must be taken because all methods have their limitations and applications. The
method shown is used because it offers a conservative estimate of runoff volume for a broad
variety of land uses and im ervions cover ercenta es.

Waters)
Mr. Steve Brumm
AAC Services, Incorporated J
5970 Fairview Road, Suite 600
Charlotte, North Carolina 28210
Dear Mr. Brumm:
Reference your application for Department of the Army (DA) authorization
to fill approximately 0.60 acre of headwater wetlands and stream channel along
Zieglers Branch, off of Wilkinson Boulevard (U.S. 29/74) and Church Street
(SR 2339) and just south of I-85, in Gastonia, Gaston County, North Carolina.
The purpose for the project is to accomodate the construction of a commercial
development (Franklin Square, Phase III).
For the purposes of the Corps of Engineers' Regulatory Program, Title 33,
Code of Federal Regulations (CFR), Part 330.6, published in the Federal
Register on November 22, 1991, lists nationwide permits. Authorization was
provided, pursuant to Section 404 of the Clean Water Act, for discharges of
dredged or fill material into headwaters and isolated waters.
Your work is authorized by this nationwide permit provided it is
accomplished in strict accordance with the enclosed conditions and provided
you receive a Section 401 water quality certification from the North Carolina
Division of Water Quality. You should contact Mr. John Dorney, telephone
[phone], regarding water quality certification. This nationwide permit
does not relieve you of the responsibility to obtain other required State or
local approval.
This verification will be valid until the nationwide permit is modified,
reissued or revoked. All the nationwide permits are scheduled to be modified,
reissued or revoked prior to 21 January 1997. It is incumbent upon you to
remain informed of changes to the nationwide permits. We will issue a public
notice announcing the changes when they occur. Furthermore, if you commence
or are under contract to commence this activity before the date the nationwide
permit is modified or revoked, you will have twelve months from the date of
the modification or revocation to complete the activity under the present
terms and conditions of this nationwide permit.
