The Stormwater Permitting Unit received a request for a plan revision for Stormwater Management Permit
Number SW61111O3 on January 25, 2012; with additional information received November 6, 2012. The plan
revision includes revisions to meet local requirements; and does not change the total allowable amount of BUA
on the site. It has been determined that a formal permit modification is not required for the proposed changes.
We are forwarding you an approved copy of the revised plans for your files.
Please be aware that all terms and conditions of the permit issued on December 9, 2011 remain in full
force and effect. Please also understand that the approval of this revision to the approved plans for the
subject State Stormwater Permit is done on a case -by -case basis. Any other changes to this project must be
submitted to and approved through the Division of Water Quality prior to construction. The issuance of this
plan revision does not preclude the permittee from complying with all other applicable statutes, rules,
regulations or ordinances which may have jurisdiction over the proposed activity, and obtaining a permit or
approval prior to construction.
If you have any questions, or need additional information concerning this matter, please contact Robert
Patterson at (919) 807-6375; or robert.patterson@ncdenr.gov.
Sincerely,

Dee Freeman
Secretary
The Division of Water Quality Central Office received a Stormwater Management Permit Application
for the subject project on November 17, 2011. A preliminary review of that information has
determined that the application is not complete. The following information is needed to continue the
stormwwater review:
/ 1.) No proposed contours are shown on the drainage plan. Please show and label all proposed
l / countours on the plan. The plan must be shown at a scale of 1"=50' or larger.
✓2. Please delineate the drainage areas to each pond on the drainage plan based on the
proposed contours.
All proposed BUA must be captured and treated in the proposed ponds. Without the
proposed grading shown it is difficult to determine, but it appears the BUA from the
following areas will bypass the proposed BMPs: lots 77-89, and most of the lots to the
southeast of Suncoast Dr. Also, lots 74-76 are not directed to the forebays.
At the small scale provided, it is difficult to determine what is happening with the grading
and collection system in the area around FES"15" and C13"14".
✓5. The stream labeled as an UT and shown on C05 needs to be shown on the drainage plan
with the required 30' vegetated setback.
'*'6. Is it the intent that the overflow weirs be used as the bypass for the level spreaders (LS)?
7. For both ponds& 2
(�a. The bottom elevations are not shown consistently in the plan views, details,
calculations, supplement forms, and O&M agreements. Also, the plan view should
show the actual excavation depth to the bottom of the sediment storage.
' b. The supplements state that drain valves are provided for maintenance/emergencies,
but that is not shown on the details. Note that pump out is an allowable option.
c. The details and calculations show four 1.0" holes for the drawdown orifice, but the
supplements show a 2.0" orifice. Please verify which is correct.

the fill slope.
9. For pond 2:
a. The overflow weir detail shows incorrect elevations.
mob. The LS length shown on the detail is not consistent with the plans, supplement, and
calculations.
Please note that this request for additional information is in response to a preliminary review. The
requested information should be received by this Office prior to December 30, 2011, or the application
will be returned as incomplete. The return of a project will necessitate resubmittal of all required
items, including the application fee.
If you need additional time to submit the information, please mail or fax your request for a time
extension to the Division at the address and fax number at the bottom of this letter. The request must
indicate the date by which you expect to submit the required information. The Division is allowed 90
days from the receipt of a completed application to issue the permit.
The construction of any impervious surfaces, other than a construction entrance under an approved
Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject to enforcement
action pursuant to NCGS 143-215.6A.
All revised original signed documents must be returned or new originals must be provided. Copies are
not acceptable. Any revised calculations or plans must be sealed, signed, and dated; and have a
revision date shown. Please reference the State assigned project number SW6111103 on all

The site contains wetlands at the western edge of the property. Otherwise the soil is sandy and
vegetation is grassy pasture. This site is fairly Flat except the area that slopes down to the wetlands.
All runoff from impervious areas will flow into catch basins in the streets. The runoff will be
treated by one of two wet detention basins.

Permanent Pool
Pollutant removal within a wet detention basin is dependent upon two integral components —
average depth and permanent pool surface area. Average depth, is a function of the surface
area, total depth, and side slopes, and must be recalculated if any of these dimensions
change. Surface area is directly proportional to the total drainage area by a factor found in a
table in the Manual. To find the factor in the table, the designer must know the percent of
impervious area and the average depth of the permanent pool. Because surface area is
dependent upon average depth, and average depth is dependent upon surface area, it
becomes necessary to iterate pond dimensions to find an acceptable solution. This is an
easy task with a spreadsheet.
[Figure 1] shows the spreadsheet values for this basin. A best guess is made for lengths and
widths at the permanent pool elevation. The spreadsheet then calculates incremental
contour areas and prismoidal volumes as well as stage and storage values. The following
values are extracted from the spreadsheet to calculate average depth:
Permanent Pool Area (PP) = 9,250 sf
Bottom of Shelf Area (BS) = 6,974 sf
Bottom of Pond Area (BP) = 1,764 sf
Depth from Bottom to Shelf (Depth)= 4.5 feet
Nov 14, 2011 Page 2 of 6
Project # 08018
Gooden & Associates, Inc.
Average Depth is calculated using method 2 in the Manual.
da = [0.25 x (1 + PS)] + I I BS z BP x /D Sth\
da = r0.25 x (1 + 6974 9250)J + [I 6974 Z 1764\ x (6974)J = 4.5 3.3 feet
We use Table 10-1 in the Manual to find the ratio of surface area to drainage area. Table 10-1 is
fed into the spreadsheet and a ratio is found by interpolation (double interpolation if necessary).
This is shown in [Figure 2].

The total permanent pool surface area shown in [Table 11 is acceptable. Regulations also
require that the forebay contain 20% of the permanent pool volume. The chosen dimensions
yield a forebay storage of 4271 cf and a total permanent pool storage of 22114 cf. The
forebay contains 19.3% of the total volume and is sized appropriately.
Nov 14, 2011 Page 3 of 6
Project # 08018
Gooden &Associates, Inc.
Temporary Pool
Regulations require treatment of the first one inch of rainfall because most common surface
pollutants are carried away within this volume. Surface characteristics reduce the treatment
depth from one inch of rainfall to some particular depth of runoff. This runoff depth — not the
rainfall depth — is then applied to the Drainage Area to compute the runoff volume that must
be treated.
The Simple formula described in Chapter 3 of the Manual is used to calculate the runoff
depth given impervious percentage and drainage area. The depth is multiplied by the total
area and then divided by 12 to get cubic feet of treatment volume (WQV).
Impervious Percentage (1)= 40.9%
Drainage Area (DA) = 551,700 sf
Treatment Depth (di) = (0.05+0.9x /)x 1 inch rainfall = 0.418 in
dT x DA 0.418 x 551700
WQV = 72 = 12 = 19,215 cf
[Figure 1] shows that at stage 6.6, the temporary pool will hold the required volume.
Draw -Down Orifice
In order to maximize filtration, the temporary pool volume should be completely drained no
sooner than 2 days. However, maximum inundation should be limited to 5 days to reduce
adverse affects on plant life and to free up space for the next storm. Regulations also
require that the treatment volume be discharged at a rate equal to or less than the 1-yr 24-hr
pre -development peak discharge rate.
The standard Orifice Equation is used to determine average flow. The treatment volume is
divided by the average flow to find the draw -down time:
Coefficient of Discharge (C) = 0.614
Orifice Diameter (D) = 1.0" (0.083 feet)

The Rational Method is used to determine the pre -development flow:
Pre -development C = 0.20
Post -development C = 0.50
Drainage Area = 12.67 acres
1-yr 24-hr storm intensity = 0.13 in/hr
Pre -development Q = C i A = 0.20 x 0.13 x 12.67 = 0.33 ft3/sec
Post -development Q = C i A = 0.50 x 0.13 x 12.67 = 0.82 ft3/sec
Flow through the orifice is 0.079 fit'/sec, which is less than the pre -development flow. The
orifice will draw -down the temporary pool volume in 2.8 days, which is meets the 2-5 day
restriction. Therefore, four 1.5 inch orifice is adequate for this pond.

Level Spreader
The riser structure should be designed such that the flow to the level spreader is as near to
2 cfs as possible while keeping the drawdown time within the 2-5 day range. The pond was
routed and the following hydrographs show the inflow into the pond and the outflow through
the riser to the level spreader. The maximum flow to the level spreader is 1.26 cfs.
The down slope vegetated filter is wooded. The level spreader must be 50 feet long per cfs.

average depth and permanent pool surface area. Average depth, is a function of the surface
area, total depth, and side slopes, and must be recalculated if any of these dimensions
change. Surface area is directly proportional to the total drainage area by a factor found in a
table in the Manual. To find the factor in the table, the designer must know the percent of
impervious area and the average depth of the permanent pool. Because surface area is
dependent upon average depth, and average depth is dependent upon surface area, it
becomes necessary to iterate pond dimensions to find an acceptable solution. This is an
easy task with a spreadsheet.
[Figure 1 ] shows the spreadsheet values for this basin. A best guess is made for lengths and
widths at the permanent pool elevation. The spreadsheet then calculates incremental
contour areas and prismoidal volumes as well as stage and storage values. The following
values are extracted from the spreadsheet to calculate average depth:
Permanent Pool Area (PP) = 11,700 sf
Bottom of Shelf Area (8S) = 9,208 sf
Bottom of Pond Area (BP) = 2,016 sf
Depth from Bottom to Shelf (Depth)= 6.5 feet

Average Depth is calculated using method 2 in the Manual.
BS day = 10.25 x I 1 + PP/1 + L\BS Z BP/ x \DBS h/J
da = 10.2S x (1 + 9200/1 t [(9208 Z 2016\ x (925 - 4.4 feet
We use Table 10-1 in the Manual to find the ratio of surface area to drainage area. Table 10-1 is
fed into the spreadsheet and a ratio is found by interpolation (double interpolation if necessary).
This is shown in [Figure 21.

The total permanent pool surface area shown in [Table 1] is acceptable. Regulations also
require that the forebay contain 20% of the permanent pool volume. The chosen dimensions
yield a forebay storage of 7,859 cf and a total permanent pool storage of 39,720 cf. The
forebay contains 19.8% of the total volume and is sized appropriately.

Temporary Pool
Regulations require treatment of the first one inch of rainfall because most common surface
pollutants are carried away within this volume. Surface characteristics reduce the treatment
depth from one inch of rainfall to some particular depth of runoff. This runoff depth — not the
rainfall depth — is then applied to the Drainage Area to compute the runoff volume that must
be treated.
The Simple formula described in Chapter 3 of the Manual is used to calculate the runoff
depth given impervious percentage and drainage area. The depth is multiplied by the total
area and then divided by 12 to get cubic feet of treatment volume (WQ1).
Impervious Percentage (n = 41.2%
Drainage Area (DA) = 824,400 sf
Treatment Depth (di) = (0.05+0.9x I)x 1 inch rainfall = 0.421 in
dr x DA 0.421 x 824400
WQV 12 12 = 28,890 cf
[Figure 1] shows that at stage 8.9, the temporary pool will hold the required volume.
Draw -Down Orifice
In order to maximize filtration, the temporary pool volume should be completely drained no
sooner than 2 days. However, maximum inundation should be limited to 5 days to reduce
adverse affects on plant life and to free up space for the next storm. Regulations also
require that the treatment volume be discharged at a rate equal to or less than the 1-yr 24-hr
pre -development peak discharge rate.
The standard Orifice Equation is used to determine average flow. The treatment volume is
divided by the average flow to find the draw -down time:
Coefficient of Discharge (C) = 0.614
Orifice Diameter (D) = 1.0" (0.083 feet)

The Rational Method is used to determine the pre -development flow:

Post -development C = 0.50
Drainage Area = 18.93 acres
1-yr 24-hr storm intensity = 0.13 in/hr
Pre -development Q = C i A = 0.20 x 0.13 x 18.93 = 0.49 ft3/sec
Post -development Q = C i A = 0.50 x 0.13 x 18.93 = 1.23 ft3/sec
Flow through the orifice is 0.086 ft3/sec, which is less than the pre -development flow. The
orifice will draw -down the temporary pool volume in 3.9 days, which is meets the 2-5 day
restriction. Therefore, four 1 inch orifices are adequate for this pond.

Level Spreader
The riser structure should be designed such that the flow to the level spreader is as near to
2 cfs as possible while keeping the drawdown time within the 2-5 day range. The pond was
routed and the following hydrographs show the inflow into the pond and the outflow through
the riser to the level spreader. The maximum flow to the level spreader is 1.44 cfs.
The down slope vegetated filter is wooded. The level spreader must be 50 feet long per cfs.
L = 50 x 1.44 cfs = 72 ft

Dear Mr. Gillis,
A site investigation has been conducted for the above referenced property, located on the
western side of Cliffdale Road, Seventy -First Township, Cumberland County, North Carolina.
'rhe purpose of this investigation was to provide a general characterization of the soils in the area
proposed for a stormwater management facility, including a determination of the depth to
evidence of a seasonal high water table and estimation of the permeability of the various soil
layers. In -situ hydraulic conductivity testing was also conducted at proposed basin one. All soil
determinations were made in accordance with the "North Carolina Stormwater Best Management
Practice Manual' and Administrative Code Section: 15A NCAC 2H A000. The materials at the
site were described in accordance with the USDA Field Bookfor Describing and.Sampling Soils.
This report represents my professional opinion as a Licensed Soil Scientist.
SOIL PROFILE DESCRIPTIONS
Soil profile descriptions were collected at the site at the locations indicated in Figure 1.
Hand powered soil auger borings were utilized to make observations. The soil
infiltration/permeability rates for the various soil horizons are estimations based on professional
interpretation and not in -situ measurements. In -situ testing was conducted and is described in
the following section "Hydraulic Conductivity Testing". The following narrative describes the
findings at the site and provides some insights and recommendations. A full description of each
observation can be found attached to this report.
Profile 1: An auger boring was dug to a depth of 72 inches below ground surface in the
bottom of the existing sediment trap. Soil morphological characteristics indicating a seasonal
high water table (SIiwn were observed at 62 inches below surface, which correlates to an
elevation of 210.16 feet. Estimated infiltration rates (permeability) range from 1.0 in/hr in the
sandy clay loam layer between 18 and 30 inches to as high as 3.0 in/hr in the sandy loam
textured soils observed between 30 and 62 inches below surface. This site appears well suited
for the proposed activity but the attached hydraulic conductivity data indicates that an infiltration
rate of 1.8 in/hr should be utilized for design purposes.

Profile 2: An auger boring was dug to a depth of 60 inches below ground surface at a
relatively undisturbed portion of the site. Soil morphological characteristics indicating a
seasonal high water table (SHWT) were observed at 50 inches below surface. Estimated
infiltration rates (permeability) range from 1.0 in/hr in the sandy clay loam layer between 18 and
45 inches to as high as 10.0 in/hr in the loamy sand textured soils observed at the surface. This
site appears well suited for a wet detention pond.
Profile 3: An auger boring was dug to a depth of 60 inches below ground surface in the
bottom of a small sediment trap at proposed wet detention pond two. Soil morphological
characteristics indicating a seasonal high water table (SHW"r) were observed at 36 inches below
surface, which correlates to an elevation of approximately 217 feet. Estimated infiltration rates
(permeability) range from 1.2 in/hr in the sandy clay loam layer at the surface to as high as 2.0
in/hr in the sandy loam textured soils observed between 30 and 54 inches below surface. This
site appears well suited for a wet detention pond with the bottom of the basin located at
approximately 217 feet. The adjacent wetlands are located at an elevation of approximately 212
to 214 feet, and it is not recommended that the basin be installed deeper than the ground
elevation at the wetlands.
HYDRAULIC CONDUCTIVITY TESTING
Hydraulic conductivity testing was conducted using a Compact Constant Head
Permeameter (CCI-IP), specifically an Amoozemeter, by using the shallow well pump -in
technique as detailed in the user's manual. Hydraulic conductivity results can vary, even within
similar soils, depending on the temperature and composition of the water used, climatic
conditions, proximity of the test layer to the water table, and other factors. Therefore, the results
from one boring may not be indicative of the entire area.
A hydraulic conductivity test was performed at Soil Profile I within the sandy loam soil
layer located above evidence of the seasonal high water table. A 3 cm radius bore hole was dug
to a depth of 49 inches below ground surface. A constant head of water was established within
the bore hole, and readings were made of the rate of water flow from the meter until it appeared
that steady state had been reached. The Glover Solution was used to calculate the hydraulic
conductivity, where Ksat = A * Q; A = {sinh-1 (H/r) — [(r/H)' + If' + r/H)/(21h); Q is the
steady-state rate of water flow from the CCHP into the bore hole; H is the depth of water in the
bore hole; and r is the radius of the bore hole. The hydraulic conductivity test shows the soil
layer transmitted water at a rate of 1.8 inches per hour. For detailed information about the test,
please refer to the attached Ksat field datasheet.
