DWQ No. 20060206, Forsyth County
The applicant is requesting a letter of concurrence from the North Carolina Wildlife Resources
Commission (NCWRC) to obtain a 404 permit from the U.S. Army Corps of Engineers. The
NCWRC has reviewed information provided by the applicant and our biologists are familiar with
habitat values of the project area. 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).
Based on our understanding of the permit application, it appears that impacts are proposed to two
streams. The stream located on Lot 4 will be impacted for a stormwater impoundment and the
stream on Lot 8 will be impacted to install a stormwater conveyance to another stormwater
structure to be built west of Lot 5. It appears that additional jurisdictional impacts may have
occurred as a drop culvert has been installed on the northwestern corner of Lot 1 on what appears
to be a substantial intermittent channel plus minor headwater impacts may have occurred by
culverting for the roadway near lot number seven (7).
Although aquatic habitat values do not appear significant, the stream to be inundated for
stormwater management on Lot 4 appears to be perennial due to flow near Abbotts Creek. We
recommend that additional stream characterizations be accomplished for the proposed northern

stormwater pond. If the stream is perennial, the stormwater impoundment should be located
further up the channel unless there are overriding issues or concerns. All remaining intermittent
and perennial streams and wetland should be buffered according to applicable water supply
watershed requirements.
Generally, we do not support placement of stormwater management ponds on jurisdictional
waters, especially on perennial waters. Irregardless of permit and certification issuance and pond
placement, we recommend the attached planting schedule for piedmont stormwater ponds to
restore lost habitat values and to reduce thermal influences in the urbanizing area. Due to urban
development in the area, all remaining waters, wetlands and forested buffers should be preserved
permanently through enforceable conservation easements, including forested areas below the
stormwater ponds. Whenever practicable, stormwater ponds should be aligned to minimize
sunlight exposure. Stormwater pond discharges and impervious area discharges should not
bypass stream buffers or be discharged directly to surface waters.
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.

Piedmont Stormwater Pond Planting Recommendations
Instead of using the typical fescue 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 Winter Wheat 120 lbs/a
Kobe lcspcdeza 20 lbs/a Kobe lcspcdeza 20 lbs/a
Shrub lespcdeza 1 lb/a Shrub lcspcdeza 1 lb/a
Switchgrass* 5lb/a Switchgrass* 5lb/ac
Add to fall or spring plantings: `Tioga' Deertongue (Panicum clandestinum) at a rate of 7 lbs. Pure Live
Seeds (PLS) per acre.
* When possible on slopes less than 3:1 use Switchgmss instead of lespedezas and on slopes greater than 3:1 use
Orchard Grass or Creeping Red Fescue. Other native species may be appropriate depending on soil, slope, and
region. Korean lcspcdeza may be appropriate in colder geophysical areas. We do not recommend Sericca
lcspcdeza. Native plants and warm season grasses are preferred over exotic plants.
Add one of the following to the above mixture:
Creeping Red Fescue 5 lbs/acre
Ladino Clover** 5 lbs/acre
Atlantic Coastal Panic Grass 5 lbs/acre (PLS)
Alfalfa** 5 lbs/acre (requires fertilizer containing Boron)
** Lime & fertilize disturbed areas according to NRCS soil test results and follow planting guidelines as appropriate
and necessary. Depending on elevation and region, other native species may be appropriate. Note that mowing
should be linuted to late winter or early spring. Mowing should only occur as needed to prevent unwanted tree
growth on a 2-3 year schedule.
The provision of shade around impounded waters can significantly reduce thermal impacts. 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 mid littoral shelf area. The following list of tree species may assist in providing habitat benefits:
Loblolly Pinc* Red Cedar Black Gum American Holly Dogwood
Hickory Sumac White Oak Willow Oak Red Maple**
Oak Viburnum Green Ash Ironwood Black Cherry
Persimmon Water Oak Spice Bush Willow (sp) Scrviccberry
Swamp Chestnut Silky Dogwood
Other species may be utilized depending on site requirements and native plant 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
near detention facility dams.
For additional information, Wildlife biologist, David Sawyer can be reached at 336-957-4855. Additional
plaiting suggestions and plant supply sources may be obtained from Stewardship biologist, Elizabeth
Hughes at 828/651-8330.

Re: Pro-Construction Notification (PCN)
Nationwide Permits 39 and 12
Stafford Centre Water Quality Ponds
Forsyth County, North Carolina
Enclosed is the Pre-Construction Notification (PCN) requesting authorization for temporary and. ,.
permanent impacts to jurisdictional streams under Nationwide Permits (NWP) 12 and 39.for the Stafford
Centre Water Quality Ponds Project. The permits are being requested for the permanent impact to a.
portion of an intermittent stream deemed to not have important aquatic function to construct a water.
quality pond (NWP 39) and for a temporary stream utility crossing (NWP 12). Timmons Group is
submitting this information on behalf of FAW Companies.
The purpose of the Stafford Center Water Quality Ponds Project is to provide stormwater.
management facilities for the proposed office park, Two water quality ponds will be constructedlo
provide stormwater control for the increased impervious cover from the office buildings'and parking,areas,..
The water quality ponds will act to better protect the streams and wetlands downstream from stormwater
flows associated with the increase in impervious cover in the area. The project is located approximately .
1200 feet north of the intersection of 1-40 and State Highway 66 near Kernersville, Forsyth County, North..,
Carolina (See enclosed Vicinity Map). The project is located on the eastern side of Abbott's Creek within
the Yadkin River watershed (USGS Hydrologic Unit Code: 03040103). .
The Jurisdictional Determination for this project has been completed and has been assigned_U.S. U.S.,
Army Corps of Engineers (USACE) Action ID 200520195. Prior to the Jurisdictional Determination,
Wetland Data Forms and Stream Quality Assessment Worksheets were completed for the on-site
jurisdictional features (See enclosed Data Forms and Worksheets). Wetlands on-site consist of palustrine
forested wetlands associated with Abbott's Creek and its unnamed tributaries (UTs). -The site contains
two UTs to Abbott's Creek. UT 1 is located in the northwest corner of the site and consists of an
unimportant intermittent stream approximately with a bankfull width of approximately 4 to 6 feet,.very
deeply entrenched, with evidence of bank failures. UT 1 lacked any clear indications of a stream with
important aquatic functions such as aquatic organisms, vegetation within the stream and/or streambanks
and the stream scored an 18 on the Stream Quality Assessment Worksheet. UT 2 is located in the
southwest corner of the site and consists of an intermittent stream with marginally important aquatic
function with a bankfull width of approximately 5 to 6 feet, deeply entrenched, with extreme bank failures.
UT 2 scored a 45 on the Stream Quality Assessment Worksheet. Photographs depicting representative
reaches of UT 1 and UT 2 have been included for review.

The proposed impacts for this project will include filling and backflooding 424.76 linear feet of UT
1 to construct a water quality pond (NWP 39) (See enclosed Wetlands Impacts Maps). UT 1 was
assessed in the field by the COE and Timmons Group and determined to be an intermittent/ephemeral
stream with no important aquatic function. Stormwater utility lines will direct stormwater from the southern
portion of the property to the water quality pond in the southwest corner of the property. The water quality
pond in the northwest corner of the property will receive stormwater runoff from the northern portion of the
project through UT 1. This water quality pond will be constructed in UT 1 and will act as a primary
stormwater control preventing untreated stormwater discharge from entering into Abbott's Creek. The
proposed project also consists of a temporary impact to 12.87 linear feet of waters of the U.S. for a utility
crossing of UT 2 to place a stormwater utility line to convey stormwater to one the southwestern water
quality pond (NWP 12) (See enclosed Wetlands Impacts?Maps). One stormwater utility line will cross UT
2 to convey stormwater to the southwest water quality pond and prevent untreated stormwater discharge
from entering into the unnamed tributary to Abbott's Creek (See enclosed Storm Sewer Profile). The
water quality pond constructed on the southwest corner of the property will not impact jurisdictional
wetlands and/or waters of the U.S. Both water quality ponds will be constructed by soil excavation and
damming, and each will have primary and emergency spillways.
No mitigation is being proposed for this project at this time. Impacts to UT 1 are permanent
impacts to an intermittent/ephemeral stream with no important aquatic function and will ultimately protect
or possibly improve the water quality of Abbott's Creek. Impacts to UT 2 are temporary impacts that will
protect the water quality of UT 2 from unimpeded stormwater flows from large areas of impervious cover.
In accordance with the general conditions`of.Nationwide Permit 12, the waters of the U.S. will be restored
to pre-construction contours upon completion of the installation of the stormwater management utility line.
Both'of these impacts are intended:to,maintain,ar improve waterquality by treating stormwater flow
before it is allowed to enter into natural systems. Based:on these designs, it is our opinion that this
project is self-mitigating.
Based on the above information,-attached'supporting documentation, and overall project purpose
and need, the applicant requests approval of the proposed activity under the provisions and conditions of
NWP-39 and NWP 12. Please review the.enclosed material and contact Eddie DuRant at [phone]

9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: The site is partially wooded and has previously been used
sporadically for silviculture. Wetlands on-site consist of palustrine forested wetlands
associated with Abbott's Creek and two unnamed tributaries (UTs). The site contains two
UTs to Abbott's Creek. UT 1 is located in the northwest corner of the site and consists of an
intermittent/ephemeral stream with no important aquatic function and with a bankfull width
of approximately 4 to 6 feet, deeply entrenched, with evidence of extreme bank failures. UT
2 is located in the southwest corner of the site and consists of an intermittent stream with
marginally important aquatic function with a bankfull width of approximately 5 to 6 feet,
deeply entrenched, with bank failures.
10. Describe the overall project in detail, including the type of equipment to be used:
The project is necessary due to the construction of an office park with paved parking lots.
Two water quality ponds will be constructed to provide stormwater control for the increased
pervious cover. Stormwater sewer lines will direct stormwater runoff from the southern
portion of the project to the water quality pond in the southwest corner of the property. One
stormwater sewer line will cross UT 2 to convey stormwater to the water quality pond and
prevent untreated stormwater discharge from entering into the tributary. The water quality
pond on the northwest corner of the property will receive the stormwater runoff from the
northern portion of the project through UT 1. The second water quality pond will be
constructed in UT 1 and will act as a primary stormwater control preventing untreated
stormwater discharge from entering into Abbott's Creek. A trackhoe and typical excavation
and construction equipment will be used for this project.
11. Explain the purpose of the proposed work: The purpose of the water quality pond
construction is to provide stormwater management for the proposed office park to better
protect the streams and wetlands downstream from stormwater flows associated with an
increase in impervious cover in the area. The purpose of the stormwater sewer line is to
direct stromwater flow from the impervious cover to the water quality ponds, thus preventing
untreated stormwater discharge from entering streams or wetlands.
IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USACE Action ID Number, DWQ Project Number, application date, and date permits and

VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: Proposed impacts will include; 11
filling 424.76 linear feet of UT 1 to construct the northwestern water quality pond (NWP 39)
and 2) a temporary impact to 12.87 linear feet of waters of the U.S. for a utility crossing of
UT 2 for the placement of a stormwater sewer line to convey stormwater to the southwestern
water quality pond (NWP 12).
2. Individually list wetland impacts. Types of impacts include, but are not limited to
mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams,

7. Isolated Waters
Do any isolated waters exist on the property? ? Yes ® No
Describe all impacts to isolated waters, and include the type of water (wetland or stream) and
the size of the proposed impact (acres or linear feet). Please note that this section only
applies to waters that have specifically been determined to be isolated by the USACE.
8. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): ® uplands ® stream ? wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.): Minor excavation with a dam, primary spillway and
emeraenev snillwav.
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): water quality (stormwater) pond
Current land use in the vicinity of the pond: Partially wooded & sporadic silviculture
Size of watershed draining to pond: Approx. 9 acres
Expected pond surface area: Approx. 0.66 acres
VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
Original design plans called for the construction of a second water quality pond to be
constructed within UT 2. The plans were redesigned to construct the southwestern water quality
pond to avoid impacts to jurisdictional wetlands and/or waters of the U.S. The site plans for the
proposed office park were also designed to avoid impacts to wetlands and waters of the U.S.
Site topography limits the location of the northwestern water quality pond. The northwestern
water quality pond was designed in its proposed location so that it could accommodate
stormwater flows from the northern portion of the proposed office park to the pond.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetiands/strmgide.btmi.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
No mitigation is being proposed for this project at this time. Impacts to UT 1 are permanent
impacts to an intermittent stream with no important aquatic function. It is estimated that the
construction of the northwestern water quality pond may ultimately protect or possibly
improve the water quality of Abbott's Creek. Impacts to UT 2 consist of temporary impacts
that will protect the water quality of UT 2 from unimpeded stormwater flows from large
areas of impervious cover. Once the stormwater sewer line is placed in UT 2 pre-
construction contours will be restored. Both of these impacts are intended to maintain or
improve water quality by treating stromwater flows before they enter into natural systems.
Based on these designs, it is our opinion that this project is self-mitigating.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http://h2o.enr.state.ne.us/wrp/index.htm. If use of the NCEEP is proposed, please
check the appropriate box on page five and provide the following information:
Amount of stream mitigation requested (linear feet):
Amount of buffer mitigation requested (square feet):
Amount of Riparian wetland mitigation requested (acres):
Amount of Non-riparian wetland mitigation requested (acres):
Amount of Coastal wetland mitigation requested (acres):
IX. Environmental Documentation (required by DWQ)
1. Does the project involve an expenditure of public (federal/state/local) funds or the use of
public (federal/state) land? Yes ? No
2. If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)?

Notes on Characteristics Identified in Assessment Worksheet
1. Consider channel flow with respect to channel cross-sectional area (expected flow), drainage area, recent precipitation, potenti
drought conditions, surrounding land use, possible water withdrawals, presence of impoundments upstream, vegetation growth
channel bottom (as indicator of intermittent flow), etc.
2. human-caused alterations may include relocation, cliaruielization, excavation, riprap, gabions, culverts, levees, berms, spoil pi
adjacent to channel, etc.
3. The riparian zone is the.area of vegetated land along each side of a stream or river that includes, but is not limited to, the
floodplain. Evaluation should consider width of riparian area with respect to floodplain width, vegetation density, maturity of
canopy and understory, species variety, presence of undesirable invasive species (exotics), breaks (utility corridors, roads, etc.
presence of drainage tiles, logging activities, other disturbances which negatively affect function of the riparian zone.
4. Evidence of nutrient or chemical discharges includes pipes, ditches, and direct draining from commercial and industrial sites,
agricultural fields, pastures, golf courses, swinuning pools, roads, parking lots, etc. Sewage, chlorine, or other foul odors,
discolored water, suds, excessive algal growth may also provide evidence of discharge.
5. Groundwater discharge may be indicated by persistent pools and saturated soils during dry weather conditions, presence of
adjacent wetlands, seeps, and springs feeding channel, reduced Soils in channel bottom. .
6. Presence of floodplains may be deternuned by topography and the slope of the land adjacent to the stream, terracing, the extent
. development within the floodplain, FEMA designation if known, etc.
7. Indicators of floodplain access include sediment deposits, wrack lines, drainage patterns in floodplain, local stream gauge data,
testimony of local residents, entrenchment ratio,. etc. Note that indicators may relic and not a result of regular flooding.
8. Wetland areas should be evaluated according to their location, size, quality, and adjacency relative to the stream channel, and r
be indicated by.beaver activity, impounded or regularly saturated areas near the stream, previous delineations, National •Wetlan(
Inventory maps, etc. (Wetlands must meet criteria outlined in 1987 delineation manual and are subject to USACE approval.)
9. Channel sinuosity should be evaluated with respect to, the channel size and drainage area, valley slope, topography, etc.
10. To evaluate sediment deposition within the channel consider water. turbidity, depth of sediment deposits forming at point bars am
in pools, evidence of eroding banks or other'sediment sources within watershed (construction sites, ineffective erosion controls)
In rare cases, typically downstream of culverts or dams, a sediment deficit may exist and should be-considered in scoring.
11. When looking at channel substrate, factor in parent material (presence of larger particles in soil horizons adjacent to the stream),
average size of substrate (bedrock, clay/silt, sand, gravel, cobble, boulder, etc.), acid diversity of particle size (riprap is excluded
12. Indications of channel incision and deepening may include a v-shaped channel bottom, collapsing banks, evidence of recent
development and increased impervious surface area resulting in greater runoff in the watershed.
13. Evaluation should consider presence of major bank failures along the entire reach under evaluation, including uprooted trees- on
banks, banks falling into channel, formation of islands in channel as they widen, exposed soil, active zones of erosion, etc.
14. Increased root depth and density result in greater bank stability. Consider the depth and density that roots penetrate the bank
relative to the amount of exposed soil on the bank and the normal water elevation.
15. Assessment of agriculture, livestock, and/or timber production impacts should address areas of stream bank destabilization,
evidence of livestock in or crossing stream, loss of riparian zone to pasture or agricultural fields, evidence of sediment or high
nutrient level's entering streams; drainage ditches entering streams; loss of riparian zone due to logging, etc:
16. Riffle-pool steps can be identified by a series of alternating pools and riffles. Abundance, frequency, and relative depth of riffles
and pools should be considered with respect to topography (steepness: of terrain) and local geology (type of substrate). .
Coastal plain streams should be evaluated for the presence of ripple-pool sequences. Ripples are bed forms found in sand bed
streams with little or no gravel that form under low shear stress conditions, whereas,. dunes and antidunes form under moderate ai
high shearstresscs, respectively. Dunes are the most connnon bed forins found in sand bed streams.
17. Habitat complexity is an overall evaluation of the variety and extent of in-stream and riparian habitat. Types of habitat to look fo
include rocks/cobble, sticks and leafpacks, snags and logs in the stream, root mats, undercut banks, overhanging vegetation, pool
and riffle connplezes, wetland pockets adjacent to chamnel, etc.
18. Evaluation should consider (lie shading effect that riparian vegetation will provide to the strcanm during the growing season. Full
sun should be considered worst case, while good canopy coverage with some,101(pe'netration is best case.
19. Stream embeddedness refers to the extent that sediment that has filled in gaps and openings around the rocks and cobble in the '
streambed. The overall size of the average particle in the streavnbed should be considered (smaller rocks will have smaller gaps).
20. Evaluation should be based on evidence of stream invertebrates gathered from multiple habitats. Scores should reflect abundance
taxa ticluness, and sensitivity of stream invertebrate types. (see attached examples of common stream invertebrates on page 4).
..21. Evaluation should include evidence of amphibians in stream channel. Tadpoles and frogs.should receive nuninnuin value,Avhile
salamanders, newts, etc. may be assigned higher value.
22. Evaluation of fish should consider the frequency and, if possible, the variety of different fish taxa observed.
23. Evaluation of wildlife should include direct observation or evidence (tracks, shells, droppings, burrows or dens, hunting stands,
evidence of fishing, etc.) of any animals using the streambed or riparian zone, to include small and large mane mials,.rodents, birds,.
reptiles, insects, etc.

YOUR VISION ACHEIVED THROUGH OURS. ® © -!!-`
Introduction
The Stafford Centre Project is located in the Town of Kernersville, Forsyth County, North Carolina.
It consists of subdividing for future development approximately 60 acres of a 76 acre site. The site
generally consists of 2 main drainage areas, one which runs from the east towards the west in the
northern half of the site, and the other drainage area flows in east to west in the southern portion of
the site. All future site development will occur upstream of these two drainage areas.
To meet regulatory requirements of controlling the 1" rainfall, the two drainage areas stormwater
outflow are controlled by wet detention ponds situated at low points. In both ponds, the runoff
flows through a riser structure, with orifice and a weir, to control the flow quantity. No requirement
exists to control quantity from this site.
The control structures for are multi-stage, to control the outflow, as indicated on the plan drawings.
The water from the outlet structures is discharged onto rip-rap aprons to provide for energy
dissipation.
Methodology
The stormwater analysis was prepared using "PondPack" software, version 9.0, The method
involves adjusting the outlet controls until the desired storage is obtained. The Soil Conservation
Service's TR-55 Tabular Hydrograph Unit Discharge procedure was used for calculating the inflow
hydrographs for the 2-year and 10-year 24-hour rainfall events. The software output was used to
determine velocity outflow from the flared end section to size the outlet protection.
Procedure
The two points of interest were determined as the point of discharge from the proposed stormwater
runoff conveyance system (Pond #1 and Pond #2). Times of concentration for both drainage areas
were calculated based upon TR-55 methodology.
The two drainage areas located on the site. The first is the area which discharges through the Pond
#1 and the second is that which drains towards Pond #2
The maximum impervious surface based upon Town of Kernersville regulations to Pond #1 is 70%
of the drainage area. The onsite drainage area is equal to 45.14 Acers, and 8.03 acres of offsite
drainage for a total drainage area of 53.17 acres. The maximum impervious surface, for which
Pond #1 is designed, is 37.22 Acres.
The maximum impervious surface based upon Town of Kernersville regulations to Pond # is 70%
of the onsite drainage area, and 50% of the offiste drainage area. The onsite drainage area is equal
to 13.60 Acers, and 25.97 acres of offsite drainage for a total drainage area of 39.57 acres. The
maximum impervious surface, for which Pond #2 is designed, is 22.51 Acres.
Stormwater routing and storage calculations, nomographs for outlet protection, drainage areas, and
other calculations are provided as an attachment.

flows associated with the increase in impervious cover in the area. The project is located approximately _-
1200 feet north of the intersection of 1-40 and State Highway 66 near Kernersville, Forsyth County, North.:-,
Carolina (See enclosed Vicinity Map). The project is located on the eastern side of Abbott's Creek within
the Yadkin River watershed (USGS Hydrologic Unit Code: 03040103). .
The Jurisdictional Determination for this project has been completed and has been assigned, U.S. ;
Army Corps of Engineers (USACE) Action ID 200520195. Prior to the Jurisdictional Determination,
Wetland Data Forms and Stream Quality Assessment Worksheets were completed for the on-site
jurisdictional features (See enclosed Data Forms and Worksheets). Wetlands on-site consist of palustrine
forested wetlands associated with Abbott's Creek and its unnamed tributaries (UTs). -The site contains
two UTs to Abbott's Creek. UT 1 is located in the northwest corner of the site and consists of an
unimportant intermittent stream approximately with a bankfull width of approximately 4.to 6 feet,.very
deeply entrenched, with evidence of bank failures. UT 1 lacked any clear indications of a stream with
important aquatic functions such as aquatic organisms, vegetation within the stream and/or streambanks
and the stream scored an 18 on the Stream Quality Assessment Worksheet. UT 2 is located in the
southwest corner of the site and consists of an intermittent stream with marginally important aquatic
function with a bankfull width of approximately 5 to 6 feet, deeply entrenched, with extreme bank failures.
UT 2 scored a 45 on the Stream Quality Assessment Worksheet. Photographs depicting representative
reaches of UT 1 and UT 2 have been included for review.

The proposed impacts for this project will include filling and backflooding 424.76 linear feet of UT
1 to construct a water quality pond (NWP 39) (See enclosed Wetlands Impacts Maps). UT 1 was
assessed in the field by the COE and Timmons Group and determined to be an intermittent/ephemeral
stream with no important aquatic function. Stormwater utility lines will direct stormwater from the southern
portion of the property to the water quality pond in the southwest corner of the property. The water quality
pond in the northwest corner of the property will receive stormwater runoff from the northern portion of the
project through UT 1. This water quality pond will be constructed in UT 1 and will act as a primary
stormwater control preventing untreated stormwater discharge from entering into Abbott's Creek. The
proposed project also consists of a temporary impact to 12.87 linear feet of waters of the U.S. for a utility
crossing of UT 2 to place a stormwater utility line to convey stormwater to one the southwestern water
quality pond (NWP 12) (See enclosed Wetlands Impacts!Maps). One stormwater utility line will cross UT
2 to convey stormwater to the southwest water quality pond and prevent untreated stormwater discharge
from entering into the unnamed tributary to Abbott's Creek (See enclosed Storm Sewer Profile). The
water quality pond constructed on the southwest corner of the property will not impact jurisdictional
wetlands and/or waters of the U.S. Both water quality ponds will be constructed by soil excavation and
damming, and each will have primary and emergency spillways.
No mitigation is being proposed for this project at this time. Impacts to UT 1 are permanent
impacts to an intermittent/ephemeral stream with no important aquatic function and will ultimately protect
or possibly improve the water quality of Abbott's Creek. Impacts to UT 2 are temporary impacts that will
protect the water quality of UT 2 from unimpeded stormwater flows from large areas of impervious cover.
In accordance with the general conditions`of.Nationwide Permit 12, the waters of the U.S. will be restored
to pre=construction contours upon completion-of the installation of the stormwater management utility line.
Both'of these impacts are intendedao'maintain.or improve water quality by treating stormwater flow
before it is allowed to enter into natural systems: Based.on these designs, it is our opinion that this
project is self-mitigating. . - .
Based on the above information,-attached'supporting documentation, and overall project purpose
'an'd need, the applicant requests approval of the proposed activity under the provisions and conditions of
NWP,39 and NWP 12. Please review the enclosed material and contact Eddie DuRant at [phone]

9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: The site is partially wooded and has previously been used
sporadically for silviculture. Wetlands on-site consist of palustrine forested wetlands
associated with Abbott's Creek and two unnamed tributaries (UTs). The site contains two
UTs to Abbott's Creek. UT 1 is located in the northwest corner of the site and consists of an
intermittent/ephemeral stream with no important aquatic function and with a bankfull width
of approximately 4 to 6 feet, deeply entrenched, with evidence of extreme bank failures. UT
2 is located in the southwest corner of the site and consists of an intermittent stream with
marginally important aquatic function with a bankfull width of approximately 5 to 6 feet,
deeply entrenched, with bank failures.
10. Describe the overall project in detail, including the type of equipment to be used:
The project is necessary due to the construction of an office park with paved parking lots.
Two water quality ponds will be constructed to provide stormwater control for the increased
impervious cover. Stormwater sewer lines will direct stormwater runoff from the southern
portion of the project to the water quality pond in the southwest corner of the property. One
stormwater sewer line will cross UT 2 to convey stormwater to the water quality pond and
prevent untreated stormwater discharge from entering into the tributary. The water quality
pond on the northwest corner of the property will receive the stormwater runoff from the
northern portion of the project through UT 1. The second water quality pond will be
constructed in UT 1 and will act as a primary stormwater control preventing untreated
stormwater discharge from entering into Abbott's Creek. A trackhoe and typical excavation
and construction equipment will be used for this project.
11. Explain the purpose of the proposed work: The purpose of the water quality pond
construction is to provide stormwater management for the proposed office park to better
protect the streams and wetlands downstream from stormwater flows associated with an
increase in impervious cover in the area. The purpose of the stormwater sewer line is to
direct stromwater flow from the impervious cover to the water quality ponds, thus preventing
untreated stormwater discharge from entering streams or wetlands.

VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: Proposed impacts will include: 1)
filling 424.76 linear feet of UT 1 to construct the northwestern water quality pond (NWP 39)
and 2) a temporary impact to 12.87 linear feet of waters of the U.S. for a utility crossing of
UT 2 for the placement of a stormwater sewer line to convey stormwater to the southwestern
water quality pond (NWP 12).
2. Individually list wetland impacts. Types of impacts include, but are not limited to
mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams,

Describe all impacts to isolated waters, and include the type of water (wetland or stream) and
the size of the proposed impact (acres or linear feet). Please note that this section only
applies to waters that have specifically been determined to be isolated by the USACE.
8. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): ® uplands ® stream ? wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.): Minor excavation with a dam, primary spillway and
emeraenev snillwav.
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): water quality (stormwaterjpond
Current land use in the vicinity of the pond: Partially wooded & sporadic silviculture
Size of watershed draining to pond: Approx. 9 acres
Expected pond surface area: Approx. 0.66 acres
VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
Original design plans called for the construction of a second water quality pond to be
constructed within UT 2. The plans were redesigned to construct the southwestern water quality
pond to avoid impacts to jurisdictional wetlands and/or waters of the U.S. The site plans for the
proposed office park were also designed to avoid impacts to wetlands and waters of the U.S.
Site topography limits the location of the northwestern water quality pond. The northwestern
water quality pond was designed in its proposed location so that it could accommodate
stormwater flows from the northern portion of the proposed office park to the pond.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.ne.us/ncwetiands/strmgide.htmi.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
No mitigation is being proposed for this project at this time. Impacts to UT 1 are permanent
impacts to an intermittent stream with no important aquatic function. It is estimated that the
construction of the northwestern water quality pond may ultimately protect or possibly
improve the water quality of Abbott's Creek. Impacts to UT 2 consist of temporary impacts
that will protect the water quality of UT 2 from unimpeded stormwater flows from lame
areas of impervious cover. Once the stormwater sewer line is placed in UT 2 pre-
construction contours will be restored. Both of these impacts are intended to maintain or
improve water quality by treating stromwater flows before they enter into natural systems.
Based on these designs, it is our opinion that this project is self-mitigating.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http://12o.enr.state.ne.us/wr2/index.htm. If use of the NCEEP is proposed, please
check the appropriate box on page five and provide the following information:
Amount of stream mitigation requested (linear feet):
Amount of buffer mitigation requested (square feet):
Amount of Riparian wetland mitigation requested (acres):
Amount of Non-riparian wetland mitigation requested (acres):
Amount of Coastal wetland mitigation requested (acres):

Notes on Cliaracteristics Identified in Assessment Worksheet
1. Consider channel flow with respect to channel cross-sectional area (expected flow), drainage area, recent precipitation, potenti
drought conditions, surrounding land use, possible water withdrawals, presence of impoundments upstream, vegetation growth
channel bottom (as indicator of intermittent flow), etc.
2. Human-caused alterations may include relocation, charmelization, excavation, riprap, gabions, culverts, levees, berms, spoil pi.
adjacent to cliamiel, etc.
3. The riparian zone is the,area of vegetated land along each side of a stream or river that includes, but is not limited to, the
floodplain. Evaluation should consider width of riparian area with respect to floodplain width, vegetation density, maturity of
canopy and understory, species variety, presence of undesirable invasive species (exotics), breaks (utility corridors, roads, etc.
presence of drainage tiles, logging activities, other disturbances which negatively affect function of the riparian zone.
4. Evidence of nutrient or chemical discharges includes pipes, ditches, and direct draining from commercial and industrial sites,
agricultural fields, pastures, golf courses, swimming pools, roads, parking lots, etc. Sewage, chlorine, or other foul odors,
discolored water, suds, excessive algal growth may also provide evidence of discharge.
5. Groundwater discharge may be indicated by persistent pools and saturated soils during dry weather conditions, presence of
adjacent wetlands, seeps, and springs feeding channel, reduced soils in channel bottom. .
6. Presence of floodplains may be determined by topography and the slope of the land adjacent to the stream, terracing, ilne extent
. development within the floodplain, FEMA designation if known, etc.
7. Indicators of floodplain access include sediment deposits, wrack lines, drainage patterns in floodplain, local stream gauge data,
testimony of local residents, entrenchment ratio,. etc. Note that indicators may relic and not a result of regular flooding.
8. Wetland areas should be evaluated according to their location, size, quality, and adjacency relative to the stream channel, and r
be indicated by.beaver activity, impounded or regularly saturated areas near the stream, previous delineations, National •Wetlanc
Inventory maps, etc. (Wetlands must meet criteria outlined in 1987 delineation manual and are subject to USACE approval.)
9. Channel sinuosity should be evaluated with respect to. the channel size and drainage area, valley slope, topography, etc.
10. To evaluate sediment deposition within the channel consider water. turbidity, depth of sediment deposits forming at pointbars an
in pools, evidence of eroding banks or other*sediment sources within watershed (construction sites, ineffective erosion controls)
In rare cases, typically downstream of culverts or dams, a sediment deficit may exist and should be.considered in scoring.
11. When looking at channel substrate, factor in parent material (presence of larger particles in soil horizons adjacent to tine stream);
average size of substrate (bedrock, clay/silt, sand, gravel, cobble, boulder, etc.), and diversity of particle size (riprap is excluded
12. Indications of channel incision and deepening may include a v-shaped channel bottom, collapsing banks, evidence of recent
development and increased impervious surface area resulting in greater runoff in the watershed.
13. Evaluation should consider presence of majorbank failures along the entire reach under evaluation, including uprooted trees. on
banks, banks falling into channel, formation of islands in channel as they widen, exposed soil, active zones of erosion, etc.
14. Increased root depth and density result in greater bank stability. Consider the depth and density that roots penetrate time bank
relative to the amount of exposed soil on the bank and the normal water elevation.
15. Assessment of agriculture, livestock, and/or timber production impacts should address areas of stream bank destabilization,
evidence of livestock in or crossing stream, loss of riparian zone to pasture or agricultural fields, evidence of sediment or high
nutrient levels entering streams; drainage ditches 'entering streams; loss of riparian zone due to logging, etc.
16. Riffle-pool steps can be identified by a series of alternating pools and riffles. Abundance, frequency, and relative depth of riffles
and pools should be considered with respect to topography (steepness: of terrain) and local geology (type of substrate). .
Coastal plain streams should be evaluated for the presence of ripple-pool sequences. Ripples are bed forms found in sand bed
streams with little or no gravel that form under low shear stress conditions, whereas,. dunes and antidunes form under moderate ar
high shearstresses, respectively. Dunes are the most common bed forams found in sand bed streams.
17.. Habitat complexity is an overall evaluation of the variety and extent of in-stream and riparian habitat. Types of habitat to look fo
include rocks/cobble, sticks and leafpacks, snags and logs in the stream, root nmats, undercut banks, overhanging vegetation, pool
and riffle complexes, wetlaimd pockets adjacent to channel, etc.
18. Evaluation should consider the shading effect that riparian vegetation will provide to the stream during the growing season. Full
sun should be considered worst case, while good canopy coverage with some 'light penetration is best case.
19. Stream embeddedness refers to the extent that sediment that has filled in gaps and openings around the rocks and cobble in time
streambed. The overall size of the average particle in the streambed should be considered (smaller rocks will have smaller gaps).
20. Evaluation should be based on evidence of stream invertebrates gathered from multiple habitats. Scores should reflect abundance
taxa richness, and'sensitivity of stream invertebrate types. (see attached examples of conunon stream invertebrates oil page 4).
..21. Evaluation should include evidence of amphibians in stream channel. Tadpoles and frogs.should receive nminimunm value,.while
salamanders, newts, etc. may be assigned higher value.
22. Evaluation of fish should consider-the frequency and, if possible, time variety of different fish taxa observed.
23. Evaluation of wildlife should include direct observation or evidence (tracks, shells, droppings, burrows or dens, hunting stands,
evidence of fishing, etc.) of any animals using the streambed or riparian zone, to include small and large nmam nals,:rodents, birds,.
reptiles, insects, etc.

Notes on Characteristics Identified in Assessment Worksheet
I. Consider channel flow with respect to channel cross-sectional area (expected flow), drainage area, recent precipitation, potential
drought conditions, surrounding land use, possible water withdrawals, presence of impoundments upstream, vegetation growth it
channel bottom (as indicator of intermittent flow), etc.
2. Human-caused alterations may include relocation, channelization, excavation, riprap, gabions, culverts, levees, berms, spoil pile
adjacent to channel, etc.
3. The riparian zone is the area of vegetated land along each side of a stream or river that includes, but is not limited to, the
floodplain. Evaluation'should consider width of riparian area with respect to floodplain width, vegetation density, maturity of
canopy and understory, species variety, presence of undesirable invasive species (exotics), breaks (utility corridors, roads, etc.),
presence of drainage tiles, logging activities, other disturbances which negatively affect function of the riparian zone.
4. Evidence of nutrient or chemical discharges includes pipes, ditches, and direct draining from connmercial and industrial sites,
agricultural fields, pastures, golf courses, swimming pools, roads, parking lots, etc. Sewage, chlorine, or other foul odors,
discolored water, suds, excessive algal growth may also provide evidence of discharge.
5. Groundwater discharge may be indicated by persistent pools and saturated soils during dry weather conditions, presence of
adjacent wetlands, seeps, and springs feeding channel, reduced soils in channel bottom.
6. Presence of floodplains may be determined by topography and the slope of the land adjacent to the stream, terracing, the extent c
. development within the floodplain, FEMA designation if known, etc.
7. Indicators of floodplain access include sediment deposits, wrack lines, drainage patterns in floodplain, local stream gauge data,
testimony of local residents, entrenchment ratio, etc. Note that indicators may relic and not a result of regular flooding.
8. Wetland areas should be evaluated according to their location, size, quality, and adjacency relative to the stream channel, and in
be indicated by.beaver activity, impounded or regularly saturated areas near the stream, previous delineations, National -Wetland
Inventory maps, etc. (Wetlands must meet criteria outlined in 1987 delineation manual and are subject to USACE approval.)
9. Channef sinuosity should be evaluated with respect to. the channel size and drainage area, valley slope, topography, etc.'
10. To evaluate sediment deposition within the channel consider water. turbidity, depth of sediment deposits forming at point bars an
in pools, evidence of eroding banks or odner"sediment sources within watershed (construction sites, ineffective erosion controls).
In rare cases, typically downstream of culverts- or dams, a sediment deficit may exist and should be-considered in scoring.
11: When looking at channel substrate, factor in parent material (presence of larger particles in soil horizons adjacent to the stream),
average size of substrate (bedrock, clay/silt, sand, gravel, cobble, boulder, etc.), and diversity of particle size (riprap is excluded)
12. Indications of channel incision and deepening may include a v-shaped channel bottom, collapsing banks, evidence of recent
development and increased impervious surface area resulting in greater runoff in the watershed.
13. Evaluation should consider presence of majorbank failures along tine entire reach under evaluation, including uprooted trees on
banks, banks falling into channel, formation of islands in channel as they widen, exposed soil, active zones of erosion, eta
14. Increased root depth and density result in greater bank stability. Consider the depth and density that roots penetrate the bank
relative to the amount of exposed soil on the bank and the normal water elevation. .
15. Assessment of agriculture, livestock, and/or timber production impacts should address areas of stream bank destabilization,
evidence of livestock in or crossing stream, loss of riparian zone to pasture or agricultural fields, evidence of sediment or high
nutrient levels entering streams, drainage ditches entering streanns; loss of riparian zone due to logging, etc:
16. Riffle-pool steps can be identified by a series of alternating pools and riffles. Abundance, frequency, and relative depth of riffles
and pools should be considered with respect to topography (stecpness:of terrain) and local geology (type of substrate). .
Coastal plain streams should be evaluated for the presence of ripple-pool sequences. Ripples are bed forms found in sand bed
streams with little or no gravel that form under low shear stress conditions, whereas,. dunes and antidunes form under moderate ai
high shearstresses, respectively. Dunes are the most common bed forms found in sand bed streams.
17.. Habitat complexity is an overall evaluation of the variety and extent of in-stream and riparian habitat. Types of habitat to look fo
include rocks/cobble, sticks and leafpacks, snags and logs in the stream, root mats, undercut banks, overhanging vegetation, pool
and riffle completes, wetland pockets adjacent to channel, etc.
18. Evaluation should consider the shading effect that riparian vegetation will provide to the stream during the growing season. Full
sun should be considered worst case, while good canopy coverage with some light penetration is best case.
19. Stream embeddedness refers to the extent that sediment that has filled in gaps and openings around the rocks and cobble in the
streambed. The overall size of the average particle in the streambed should be considered (smaller rocks will have smaller gaps).
20. Evaluation should be based on evidence of stream invertebrates gathered from multiple habitats. Scores should reflect abundance
taxa richness, and'sensitivity of stream invertebrate types. (see attached examples of common stream invertebrates on page 4). .
21. Evaluation should include evidence of amphibians in stream channel. Tadpoles and frogs.should receive nnininmum value,.while
salamanders, newts, etc. may be assigned higher value.
22. Evaluation of fish should consider the frequency and, if possible, the variety of different fish taxa observed.
23. Evaluation of wildlife should include direct observation or evidence (tracks, shells, droppings, burrows or dens, hunting stands,
evidence of fishing, etc.) of any animals using. die streambed or riparian zone, to include small and large mammals,: rodents, birds,
reptiles, insects, etc.

YOUR VISION ACHEIVED THROUGH OURS. * Q O _r??
Introduction
The Stafford Centre Project is located in the Town of Kernersville, Forsyth County, North Carolina.
It consists of subdividing for future development approximately 60 acres of a 76 acre site. The site
generally consists of 2 main drainage areas, one which runs from the east towards the west in the
northern half of the site, and the other drainage area flows in east to west in the southern portion of
the site. All future site development will occur upstream of these two drainage areas.
To meet regulatory requirements of controlling the 1" rainfall, the two drainage areas stormwater
outflow are controlled by wet detention ponds situated at low points. In both ponds, the runoff
flows through a riser structure, with orifice and a weir, to control the flow quantity. No requirement
exists to control quantity from this site.
The control structures for are multi-stage, to control the outflow, as indicated on the plan drawings.
The water from the outlet structures is discharged onto rip-rap aprons to provide for energy
dissipation.
Methodology
The stormwater analysis was prepared using "PondPack" software, version 9.0, The method
involves adjusting the outlet controls until the desired storage is obtained. The Soil Conservation
Service's TR-55 Tabular Hydrograph Unit Discharge procedure was used for calculating the inflow
hydrographs for the 2-year and 10-year 24-hour rainfall events. The software output was used to
determine velocity outflow from the flared end section to size the outlet protection.
Procedure
The two points of interest were determined as the point of discharge from the proposed stormwater
runoff conveyance system (Pond #1 and Pond #2). Times of concentration for both drainage areas
were calculated based upon TR-55 methodology.
The two drainage areas located on the site. The first is the area which discharges through the Pond
#1 and the second is that which drains towards Pond #2
The maximum impervious surface based upon Town of Kernersville regulations to Pond #1 is 70%
of the drainage area. The onsite drainage area is equal to 45.14 Acers, and 8.03 acres of offsite
drainage for a total drainage area of 53.17 acres. The maximum impervious surface, for which
Pond #1 is designed, is 37.22 Acres.
The maximum impervious surface based upon Town of Kernersville regulations to Pond # is 70%
of the onsite drainage area, and 50% of the offiste drainage area. The onsite drainage area is equal
to 13.60 Acers, and 25.97 acres of offsite drainage for a total drainage area of 39.57 acres. The
maximum impervious surface, for which Pond #2 is designed, is 22.51 Acres.
Stormwater routing and storage calculations, nomographs for outlet protection, drainage areas, and
other calculations are provided as an attachment.
