STORAGE ANALYSIS D E C E I E D
FOR
SANDPIPER GOLF COURSE PUD FEB 2 21999
AT
BRUNSWICK COUNTY, NC D E M
PRG,i N
PROJECT DESCRIPTION:
Sandpiper Bay Planned Unit Development (PUD) Phase I is. to
consist of 71 residential lots (21.82 acres) located adjacent to
an existing golf course at Sandpiper Bay Golf Plantation in
Brunswick County, North Carolina. The Golf Course was designed,
permitted and constructed in 1986-1987. The original design was
for an 18-hole golf course with residential outparcels along the
main entrance drive. Since we have been unable to obtain the
previously approved drainage calculations from either the golf
course designers or the NC Department of Natural Resources, we
are performing TR-55 storage approximation calculations to
determine if the existing lakes are capable of storing the entire
10-year storm event.
EXISTING CONDITIONS:
The existing golf course and outparcels consist of
approximately 273 acres. However, approximately 58 acres outfall
across Old Georgetown Highway and is not germane to this
analysis.
The remainder of the site drains to four interconnected
lakes identified as lakes A,B,C and D on the attached maps. All
stormwater in this area is retained on -site for use in irrigation
for the golf course. The irrigation pumps are located at Lake B,
which is connected through a piped system with a gate valve which
is opened or closed to keep the elevation of the irrigation pond
constant. The only outflow for this lake system is through a
vegetated emergency spillway section located at the west side of
Lake B. The static water surface elevation of these lakes is
53.20' MSL with the spillway elevation at approximately 55.701.
The storage capacity of the remainder of the lakes (A,C and D) is
considerably higher when the gate valve to Lake B is closed.
However, for the purpose of this analysis the gate valve was
assumed to be open (worst case scenario).
The existing soils consist mostly of Leon Soils (HSG B) with
a small portion of the site (approx. 37 ac.) containing Croatan

Muck (HSG D). The areas containing Croatan soils are undeveloped
and wooded.
DRAINAGE ANALYSIS:
The drainage hydrographs were developed with Engineering
Data Systems Watershed Modeling Software, Version 12. This
software generates hydrographs based on the TR-55 Method. The
storage approximation was performed manually per TR-55
methodology (Chapter 6). Drainage and lake areas were determined
from a compilation of previous construction drawings, soils maps,
aerial photographs, USGS maps and on -site surveys and
inspections. only the 10-year storm was evaluated for storage
approximation.
Existing drainage structures have been incorporated in the
storm drainage design for the residential subdivision. Hydraulic
Grade Line Calculations have been performed to ensure the
capability of both new and existing systems to accommodate the
stormwater runoff.

Storage Approximation Calculations
Per TR-55 Chapter 6
1. Total Site Area = 214.61 AC = .3353 MI2-
2. Average Curve Number = 71
3. Existing Lake Data:
Total Acreage = 24.15 Acres
Minimum Storage Available =2.5'
Total Storage Available = 2,752,400 Ft3
4. Determine inflow Hydrograph (See Pages 9 thru 18)
Qp = 131.9 CFS
5. Determine VSNr - since outflow is zero utilizing the highest value in Figure
6.1.
VSNr = .56
6. Determine Q - use Figure 2.1 with P= 6.7 in. & CN = 71
7. Determine Runoff volume:
Vr = QAJ53.33) = (3.4)(.335.3)(53.33) = 60.76 AC -Ft
The existing lakes are capable of retaining the entire 10-year storm event.
Furthermore, since the storage approximation method tends to overestimate storage
requirements by up to 25%, these calculations are extremely conservative.

REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 980707 Modification
Sandpiper Bay Golf Plantation, Phase I
Brunswick County
Dear Mr. D'Errico:
The Wilmington Regional Office received a modification to the Stormwater Management Permit
Application for Sandpiper Bay Golf Plantation, Phase I on November 23, 1998. A preliminary review of
that information has determined that the application is not complete. The following information is needed
to continue the stormwater review:
1. Please include all previously permitted development on the application, and incorporate the
proposed changes in that data. If I accept the application as submitted, the only thing
permitted will be the 2 changes. When we receive a modification, we get rid of the previously
submitted documentation and replace it with the new documentation. Having 2 or 3
applications in the file each covering a different modification is too confusing. When a
modification is submitted, it needs to cover all the previously permitted development and
incorporate the changes. Please revise the application to cover the proposed 71 lots, the
existing clubhouse, road and cartpaths, and the new road; as well as how these numbers are
affected due to the increases requested by this modification. I have enclosed a copy of the
previous application for your convenience in revising the current application.

STORAGE ANALYSIS
FOR
SANDPIPER GOLF COURSE PUD
AT
BRUNSWICK COUNTY, NC
PROJECT DESCRIPTION:
E C E I V E
NOV 2 31998 D
F•RCG.i
D E M
Sandpiper Bay Planned Unit Development (PUD) Phase I is to
consist of 71 residential lots (21.82 acres) located adjacent to
an existing golf course at Sandpiper Bay Golf Plantation in
Brunswick County, North Carolina. The Golf Course was designed,
Dermitted and constructed in 1986-1987. The original design was
for an 18-hole golf course with residential outparcels along the
main entrance drive. Since we have been unable to obtain the
previously approved drainage calculations from either the golf
course designers or the NC Department of Natural Resources, we
are rarforming TR-55 storage approximation calculations to
determine if the existing lakes are capable of storing the entire
10-year storm event.
EXISTING CONDITIONS:
The existing golf course and outparcels consist of
approximately 273 acres. However, approximately 58 acres outfall
across Old Georgetown Highway and is not germane to this
analysis.
The remainder of the site drains to four interconnected
lakes identified as lakes A,B,C and D on the attached maps. All
stormwater in this area is retained on -site for use in irrigation
for the golf course. The irrigation pumps are located at Lake B,
which is connected through a piped system with a gate valve which
is opened or closed to keep the elevation of the irrigation pond
constant. The only outflow for this lake system is through a
vegetated emergency spillway section located at the west side of
Lake B. The static water surface elevation of these lakes is
53.20' MSL with the spillway elevation at approximately 55.701.
The storage capacity of the remainder of the lakes (A,C and D) is
considerably higher when the gate valve to Lake B is closed.
However, for the purpose of this analysis the gate valve was
assumed to be open (worst case scenario).
The existing soils consist mostly of Leon Soils (HSG B) with
a small portion of the site (approx. 37 ac.) containing Croatan

dl
Muck (HSG D). The areas containing Croatan soils are undeveloped
and wooded.
DRAINAGE ANALYSIS:
The drainage hydrographs were developed with Engineering
Data Systems Watershed Modeling Software, Version 12. This
software generates hydrographs based on the TR-55 Method. The
storage approximation was performed manually per TR-55
methodology (Chapter 6). Drainage and lake areas were determined
from a compilation of previous construction drawings, soils maps,
aerial photographs, USGS maps and on -site surveys and
inspections. Only the 10-year storm was evaluated for storage
approximation.
Existing drainage structures have been incorporated in the
storm drainage design for the residential subdivision. Hydraulic
Grade Line Calculations have been performed to ensure the
capability of both new and existing systems to accommodate the
stormwater runoff.

Sandpiper Bay Golf Course
Storage Approximation Calculations
Per TR-55 Chapter 6
1. Total Site Area = 214.61 AC = .3353 M12-
2. Average Curve Number = 71
3. Existing Lake Data:
Total Acreage = 24.15 Acres
Minimum Storage Available =2.5'
Total Storage Available = 2,752,400 Ft3
4. Determine inflow Hydrograph (See Pages 9 thru 18)
Qp = 131.9 CFS
5. Determine Vs/Vr - since outflow is zero utilizing the highest value in Figure
6.1.
VsNr = .56
6. Determine Q - use Figure 2.1 with .P= 6.7 in. & CN = 71
7. Determine Runoff volume:
Vr = QAm(53.33) = (3.4)(.3353)(53.33) = 60.76 AC -Ft
The existing lakes are capable of retaining the entire 10-year storm event.
Furthermore. since the storage approximation method tends to overestimate storage
requirements by up to 25%, these calculations are extremely conservative.

Input requirements and procedures
Use figure 6.1 to estimate storage volume (Vs)
required or peak outflow discharge (qo). The most
frequent application is to estimate Vs, for which the
required inputs are runoff volume (Vr), qu, and peak
inflow discharge (qi). To estimate qo, the required
inputs are Vr, VA, and qi.
1
Estimating Vs
Use worksheet 6a to estimate Vs, storage volume
required, by the following procedure.
1. Determine qo. Many factors may dictate the
selection of peak outflow discharge. The most
common is to limit downstream discharges to a
desired level, such as predevelopment discharge.
Another factor may be that the outflow device
has already been selected.
2. Estimate qi by procedures in chapters 4 or 5. Do
not use peak discharges developed by any other
procedure. When using the Tabular Hydrograph
method to estimate qi for a subarea, only use
