Dear Ms. Lewis:
Per your recent request for additional information, we have revised Plan Sheets C-3 and C-5.
We are providing these sheets and the requested computations for your review.
The following is a response to each of your comments:
1. The drainage areas are delineated on the plans and included in the calculations.
2. The drainage area for each of the ponds has been added to the plans.
3. The plan sheets and calculations have been signed and sealed.
4. The outlet structures are labeled on the plans.
5. The 1" storage level is shown on the pond details.
6. The permanent pool and design pool contours are shown on the plans.
7. As we discussed, the weepholes have hardware cloth coverings and #57 stone
filter to prevent clogging. The grates for the inlets have been changed to
prevent clogging. The detail for this grate is attached.

8. The forebay weir has been raised to the permanent pool elevation.
9. The parking lot entrances have been revised to insure that the impervious
surfaces drain to the ponds.
10. A note has been added to each pond detail to require that slopes be 3:1, or
flatter.
11. The pond data has been separated on the application form.
12. The calculations for the drawdown holes are provided.
13. The attached calculations show the correct surface areas.
14. The SA/DA calculations have been provided for each pond, in accordance with
the table you provided.
We hope that these revised plans and additional calculations are sufficient for your approval,
so that we may obtain the required permit. This is critical, as the client has already begun the
bidding process and is anxious to proceed with this project.
If you have any questions, or need additional information, please do not hesitate to call me.
Thank you for your assistance on this project.

Dear Mr. King:
The Wilmington Regional Office received a Stormwater Management Permit Application for Naval
Hospital Parking Lot Additions on March 26, 1996. 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. The pond's volume is required to be calculated for the drainage basin to the pond, which
includes the proposed impervious area, and all other drainage (both impervious and grassed)
within the basin that cannot be routed around the pond.
✓2. Clearly delineate each pond's drainage area on the plans.
/ 3. Provide sealed copies of the design plans.
0%4. Label the outlet structure location on the plans.
L/5. Draw and label the 1" storage elevation on the pond detail.
�6. Draw and label the permanent pool and design pool contours on the plans. This Office must
be able to verify the surface areas you report.
c/7. Provide a trash guard for the 3/4" weepholes and the overflow from the pond.
1/ 8. Raise the forebay weir elevation to at least the permanent pool elevation.

9. A portion of each parking lot's entrance drive does not drain to the pond. All impervius
areas associated with the development of a high density project must be directed into an
engineered system.
10. A minimum 3:1 side slope is required above the permanent pool. Please note on the pond
section detail. You have noted a 3:1 below the permanent pool.
11. Please split out the ponds on the application form. Label the "Drainage basin" columns as
East and West and fist the individual statistics for each pond.
12. Provide drawdown calculations in support of the multiple 3/4" orifices you have specified
as the drawdown devices on the plans. I cannot find where in the calculations you arrived
at the 3/4" size, nor can I find where the orifice was showm to'draw down the pond within
the specified 2-5 day period. The calculations pertaining to 10 year and 100 year storm
event routing are not required by this Office, only those requirements as listed in NCAC
2H.1000.
13. Is the "Max Surf Area" noted in the calculations the surface area provided at the 1" design
storm elevation?
14. The State -has minimum surface areas that must be met based on the percent imperviousness
of the drainage area, the TSS removal rate, and the depth of the pond. You have not
provided information indicating compliance with this requirement. Attached is the SA/DA
chart for your use.
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 May 29, 1996, 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 have any questions concerning this matter please feel free to call me at (910)
395-3900.
Sincerely,
Ms. Linda Lewis

CAMP LEJEUNE NAVAL HOSPITAL PARKING LOT ADDITION
STORMWATER NARRATIVE
Project Description
The purpose of this project is to extend both the patient and staff parking lots at the Naval
Hospital on Camp Lejeune Naval Base. The project consists of two separate lots to be extended
radially outward with associated lighting fixtures and landscaping. Stormwater ponds will be
provided to detain the first inch of runoff from the proposed impervious areas. The total
proposed impervious area is approximately 1.7 acres.
Site Description
The Naval Hospital currently has two separate lots - staff and patient - which are separated by
'B' Street (the entrance to the hospital) and 'D' Street. Behind the staff lot, there is a grass field
and small wooded area (mostly large pines) which will be removed. Behind the patient lot is a
soccer field and a small wooded area of which a portion will be cleared. The proposed
extensions will not tie to existing drainage system but will have detention ponds to handle
stormwater runoff. These ponds will be used as sediment basins during construction.
Soils
From boring logs at the time of the original Hospital construction, the native soils near the
surface are predominately fine sands, with some clays and silts. Soils at depths of 6 to 10 feet
contain clayey materials. Based on this limited data, we estimate that these native soils might
be type SC or ML soils. Groundwater was measured at a depth of 8 feet in some of the borings.
Storm Drainage Design
The storm drainage system is designed for the 10-year storm. Run-off is calculated using the
Rational Method and the Kirpich equation. Storm Drainage piping is sized to flow just full,
without a surcharge in the system. The system calculations are attached.
Stormwater Detention Calculations
The two stormwater ponds for this project are designed to collect the first inch of runoff and
detain this volume of water for three to five days. After the three to five day "drawdown" time,
the water level in these ponds will return to the normal pool elevation. The ponds will collect
the runoff from the proposed development only. Both ponds will be wet ponds with a normal
K:\CIV\39419-06\W_P\RP7\STORMNARDOC 2

pool elevation of approximately three feet. Flood storage is provided above this normal pool
elevation.
The post -development run-off hydrograph was computed using small -watershed hydrograph
methodology, developed by H. Rooney Malcolm, P.E., PhD, of North Carolina State University.
The 6-hour, 10-year design hydrograph represents the pond inflow.
Analysis of the stage -storage -discharge relationship for each of the ponds was performed using
modified storage -indication routing methodology developed by Dr. Malcolm. This methodology
develops a stage -storage function to describe the geometry of the pond. The relationship between
the inflow hydrograph, storage volume and outflow rate was analyzed for a variety of pond and
outlet configurations. The ponds were designed to pass the 100-yr post -development storm
without over -topping the dam.
See the attached calculations for a summary of the computations for each of the permanent
ponds.
The proposed ponds are to be used as temporary sediment basins for erosion control. Upon site
stabilization, the filter stone will be cleaned, and utilized to prevent clogging of the drawdown
holes. The ponds will be cleaned of sediment and the restored to the required shape.
