Laurie,
T just spoke to Mark Brambell with St. James, he really heads up the
development portion of that group, and he said that there were no utilites
on our project site. There are of course utilities within the ROW of St.
James Drive. He said he'd go with us to answer any of those types of
questions. He's our contact with St. James and knows the area really well.
We can meet at Mark's office, St. James development, which is the very first
building on the right after the entrance. Tt would be a convenient meeting
spot. Let me know if that's okay. Thanks.
Jeff

Jeff,
You.are correct. If you can prove that you can store/infiltrate the 25
year-24 hour storm and hold the 1" storm without infiltration, you do
not need a bypass. The supplement has to show the design storm as the
25 year-24 hour storm (approximately 811) and the corresponding volume
(approximately 3450 cubic feet). So, I need for you to change the front
sheet of the supplements and provide calculations for the 8" storm
(runoff volume). You can just bring these tomorrow. Also, the
calculations show that the infiltration occurs in a swale, but this is
the basin, correct?
Let me know if this doesn't make sense. It is difficult to communicate
in an email sometimes.
Everything else looks good. See you at the site at 9:30.

Dear Ms. Munn:
Please find the enclosed response to your request for additional information for the above
referenced project.
1. A curb and gutter detail has been added to the plans.
2. The infiltration basin detail has been revised to show a 4" layer of clean sand.
3. In the past, we have been able to permit oversized infiltration systems without
a bypass. We were required to show that the system could contain and
infiltrate the 25yr-241ir event without any discharge and also show that the
system would not flush in the I Oyr-1 Omin event. This design should have
been called out on the Infiltration Basin Supplement's checklist and in the
narrative, but was not. I'm including a revised initialed checklist and
narrative to clear up this oversight.
4. A vegetated swale detail is on the plans.
5. We are available to meet whenever your schedule allows.

Dear Mr. Atkinson:
The Wilmington Regional Office received a Stormwater Management Permit Application for The
Founders Club Parking Lot Expansion on July 18, 2003. A preliminary review of that information has
determined that the application is not complete. The following information is needed to continue the
stormwater review:
Please provide a curb and gutter detail on the plans.
Please revise the basin detail to show a 4" layer of clean sand on the bottom of the basin.
The excess runoff must bypass the device before it enters the basin. I have enclosed
some details in my copy to the engineer.
4. Please provide a detail of the vegetative filter.
Please contact me to set up a time for Vincent Lewis, State Soils Scientist, to do an on -
site investigation.
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 September 13, 2003, 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

Jeff,
I am reviewing the above project. Our soils scientist Vincent Lewis
will need to do a soils investigation. Do you know if he has already
been to this site? If not, do you want me to set something up? He will
be out of town through next Wednesday, but I can maybe get him on the
schedule for the end of next week or the beginning of the week of the
25th. It is not necessary for you to meet us out there, but you are
welcome to come. It is helpful when the engineer is there so that you
can tell us where the basins are going to be on the site. I don't think
that will be an issue on such a small site though.
Just let me know. I am going to send some comments out today.
Thanks,
Laurie

DESIGN NARRATIVE
1. GENERAL:
The project site is located within St. James Plantation adjacent to the Founders Club in
Brunswick County, North Carolina. The project area for the parking lot expansion is
approximately 0.92 acres. Drainage considerations are to be in accordance with state storm water
requirements.
2. EXISTING SITE:
Site topography in the area is relatively flat with slopes typically less than one (1) percent. The
vegetation consists primarily of minor ground cover and a thin stand of trees within the area of
the improvements. Subsurface soils are typically a mixture of sands, silty sands and organics.
3. PROPOSED IMPROVEMENTS:
Improvements proposed include the construction of a 30 space asphalt parking lot. The site will
be graded to divert all storm water runoff into two curb cuts draining to the proposed infiltration
trenches. The trenches will be roughed in first and will be utilized to collect and contain any
sediment during construction from leaving the site.
4. DRAINAGE CALCULATION CONSIDERATIONS:
Attached to this design narrative are the drainage calculations determining the amount of storm
water to be contained and treated in the two systems. The infiltration trenches are oversized to
be able to contain and infiltrate the 25-year, 24-hour storm event. They are also sized to prevent
flushing in the 10-year, 10-minute event. With this oversizing, all runoff from impervious
surfaces is directed to the treatment devices without a bypass system.
5. EROSION CONTROL CONSIDERATIONS:
The proposed infiltration trenches will be used as trapping devices during construction and have
sufficient storage for the calculated amount of disturbance. Also, the lower slope perimeter will
be enclosed in silt fence as shown on the plan for added protection. The area of disturbance is
limited to within the project area.
6. MAINTENANCE CONSIDERATIONS:
During construction, the Contractor shall be required to inspect and repair as needed all erosion
control devices after any significant rain event. Any measure found not performing its intended
function, shall be repaired immediately. Upon completion of construction the establishment of

S. EROSION CONTROL CONSIDERATIONS:
The proposed infiltration trenches will be used as trapping devices during construction and have
sufficient storage for the calculated amount of disturbance. Also, the lower slope perimeter will
be enclosed in silt fence as shown on the plan for added protection. The area of disturbance is
limited to within the project area.
G. MAINTENANCE CONSIDERATIONS:
During construction, the Contractor shall be required to inspect and repair as needed all erosion
control devices after any significant rain event. Any measure found not performing its intended
function, shall be repaired immediately. Upon completion of construction the establishment of
permanent ground cover will be a priority.

Erosion and Sedimentation Control
1.01 General: The contractor shall be responsible for erosion and sedimentation
control within the construction limits; for prevention of sediment laden ninoff leaving the
construction limits or entering ditches, streams or water impoundments; and for
implementation of necessary erosion and sedimentation control measures to meet the
requirements of the North Carolina Department of Environment, Health, and Natural
Resources. The Contractor shall also be responsible for all damages or fines resulting
from erosion or sediment laden runoff in the execution of his contract.
1.02 Construction Sequence: While the use of erosion and sedimentation control
devices is especially important on areas of steep topography, easily erodible soils and
sites in close proximity to water courses throughout the construction period, the control
measures should be installed prior to the commencement of land clearing and shall be
frilly maintained and periodically inspected until final restoration and stabilization is
completed. Unrestored cleared areas shall be kept to a minimum. Disturbed areas ahead
of construction shall only be accomplished on those segments for the shortest practical
distance as required for continual progress.
Final restoration shall not be delayed until completion of the project but will be carried
out in phases as the work proceeds. Under no circumstances will any areas be left
denuded for more than (15) fifteen calendar days without some form of stabilization until
final restoration is complete.
1.03 Sedimentation: Control Measures: The following are some of the sediment
control devices or measures that may be required to prevent sedimentation of streams,
water courses, or drainage structures:
l . Earth berms and/or diversion and intercept ditches.
2. Sediment traps
3. Filter berms
4. Filter inlets
5. Silt fences - not to be placed in streams or ditches perpendicular to flow.
G. Check dams gravel filter
7. Gravel construction exit
1.03.1 Erosion Control Measures: Some of the soil erosion control measures which
may be required in this contract are:
l . Earth slope protection
2. Diagonal water break diversion berms
3. Diversion channels
4. Preservation of existing vegetation
5. Storm inlet protection
G. Stream crossings

7. Energy dissipators
& Matting of re -seeded areas
1.03.2 Detail Drawing: Examples of sedimentation and erosion control details are
shown in these plans for installation at locations designated in the plans or as otherwise
required by the regulating agency, or the owner as work proceeds.
1.04 Stream Protection: Where construction activities are necessary in close proximity
to streams, and other waterways, they shall be performed in a manner that does not
contribute to degradation of or blockage of the stream -flow. In order to prevent possible
degradation or blockages, the contractor shall be required to:
1. Keep all construction debris, excavated materials, brush, rocks, refuse and topsoil
as far from these waterways as possible. Restrict machinery operation or stream
crossings in waterways to the extent necessary for construction of utilities crossings.
2. If construction work areas are necessary in a waterway, they shall be protected as
indicated on the plans.
3. If temporary roadways are essential for the construction activities, they shall be
constructed of soils which are not highly erodible materials and must not span more than
half way across the water course or wetland area at any one time unless otherwise
approved by the Engineer. These temporary roadways shall be entirely removed as soon
as their requirement is met. Work in these areas shall follow the requirements of the
Corp of Engineers or CAMA permit, or plans as applicable.
1.05 Construction Access: The travel of equipment to and from the construction areas
shall be minimized not only to protect areas that will not be denuded, but also to prevent
the spreading of sediment within and outside of the construction areas. Therefore, special
construction equipment travel corridors will be established for this use and instructions
shall be issued for their use. Use of these corridors must be fully enforced. Other non-
essential traffic will be restricted or discouraged. Indiscriminate and convenience traffic
shall not be allowed.
1.06 Stockpile/Barrow Areas: The Contractor shall be responsible for selecting,
obtaining and maintaining stockpile or borrow areas which he may require to complete
the contract. He is also required to design and incorporate all necessary sediment and
erosion controls measures necessary to prevent erosion and contribution of sediment to
adjacent areas. The Contractor is responsible to obtain all necessary permits or approvals
for borrow or spoil areas outside the construction limits.
1.07 Disposal of Excess Water from Excavations: The Contractor shall practice
management of excess water pumped from excavation to reduce the production and
spreading of sediment. Pumped water shall be discharged onto stabilized surfaces and
allowed to filter through existing vegetation if possible; otherwise, additional control
measures may be necessary. If ditches are required to remove pumped water from

construction excavations, they shall be given the same consideration as any other man-
3nade waterway and they shall be stabilized as to not degrade and produce sediment.
1.08 Excavation and Backfill: Fxcavation shall he closely controlled and all the
material removed from the excavation shall be selectively stockpiled in areas where a
minimum of sediment will be generated and where other damage will not result from the
piled material. Drainage ways shall be protected at all times and the placement of
material in Drainage ways for convenience shall not be allowed. Backf (ling operations
shall be performed in such a manner that remaining trees are not damaged.
1.09 Final Grading and Seeding: Finish grading, topsoiling, seeding and/or sodding
shall be perfonned after the constniction phase is complete. Permanent vegetation of the
areas, that have been disturbed, shall be re-established as rapidly as possible. If the
completion of the construction activities do not coincide with a season in which
pen-nanent vegetation can be generated, an interim or temporary program is required.
This shall include soil conditioners and mulching as necessary for soil stabilization. In
any case, sediment and erosion controls shall be installed promptly and their maintenance
assured.
1.10 Approval: The approved Erosion Control Plan will be provided by the Owner.
Any standard conditions relating to soil erosion and sediment control issued to the
Contractor as a part of any permits shall be available at the job site at all times.

I = Percent Impervious = Impervious portion of the drainage area (acres) 1 Drainage area (acres)
Rv = 0.05 + 0.009(I)
Rv = 0.05 + 0.009 * 66.7 = 0.650 (in/in)
Volume to be controlled from the design storm event:
where: Design rainfall
Rv
Drainage Area
1.0 (in)
- 0.650 (in/in)
= 0.18 (acres)
Volume required (cf) = rainfall (in) x Rv (in/in) x Drainage Area (acre) x 1/12(feet/inches) x 43560 (sflacre)
Vreq'd = 1.0 * 0,650 * 0.18 * 1112 * 43560 = 425 cubic feet
