Tarawa Terrace Housing, Marine Corps Base
Camp Lejeune, North Carolina
1, SITE DESCRIPTION
a) Nature and purpose of construction activity — to provide 234 new family housing units at
Tarawa Terrace, Camp Lejeune, North Carolina. The work includes the design and
construction of new housing, demolition of existing buildings, site improvements, and
utility services.
i) The site is on the site of an existing housing development. All existing structures
will be demolished and the site cleared prior to construction of the new units.
Major streets and utilities will remain in place. It has been reported by the Owner
that no wetlands are present in the project limits.
ii) The Construction of this project will be accomplished in two phases. Phase
includes the demolition of existing housing and the construction of 112 new
housing units. Phase II includes the demolition of existing housing and the
construction of 122 new housing units. This erosion and sedimentation control
plan and Stormwater management plan covers the construction phases of the
project.
b) Intended sequence of major activities — major construction activities will occur
approximately in the following order:
i) Site Clearing and Demolition (Phase 1)
ii) Earthwork and Temporary Stabilization (Phase 1)
iii) New Construction and Permanent Stabilization (Phase 1)
iv) Site Clearing and Demolition (Phase 11)
v) Earthwork and Temporary Soil Stabilization (Phase II)
vi) Infrastructure & Stormwater Facilities Construction and Permanent Soil
Stabilization (Phase 11)
vii) Building Construction
c) Estimated area to be disturbed - 37 acres
d) Description of existing soils types — A soils investigation was performed to identify the
existing soil conditions at the site. Soil samples were classified according to the
"Unified Classification System." The predominant soil types consist of clean sand (SP),
slightly silty sand (SP-SM), clayey sand (SC) and silty sand (SM), with minor amounts of

Camp Lejeune, North Carolina
fat clay (CH) and sandy silt (MH). Groundwater was observed in test borings and hand
augers at a depth of approximately 5.0 to 18.5 feet.
e) Existing vegetation — The existing site is developed with housing units, streets and
parking areas. There are several groups of small trees and lawn areas surrounding the
building units. The demolition phase of the project consists mainly of removing the
existing structures without significant land alteration or vegetation removal.
f) Receiving waters — Stormwater runoff from the Tarawa Terrace development is
collected and routed to the adjacent Northeast Creek located south and east of the
existing development. There is a large natural, vegetated buffer that separates Tarawa
Terrace from the creek that will remain undisturbed by this project.
g) Site map- See erosion and sedimentation control plans.

Camp Lejeune, North Carolina
2) EROSION AND SEDIMENT CONTROL
a) Stabilization practices — all denuded areas that will be dormant for extended periods of
time shall be seeded with fast germinating temporary vegetation immediately following
grading. Selection of seed mixture will depend on the time of year when it is applied.
See the North Carolina Erosion and Sediment Control Design Manual for selection of
the seed mixture.
b) Erosion and Sediment Control - Structural Practices
i) Silt Fence — silt fence sediment barriers will be installed down -slope of areas with
minimal grades to filter sediment -laden runoff from sheet flow as indicated on the
plans.
ii) Inlet Protection — all storm sewer inlets shall be protected during construction.
Sediment laden water shall be properly filtered before entering the storm sewer
system.
iii) Stabilized Construction Entrance — an approved construction entrance will be
constructed anywhere construction traffic is allowed to leave the site.
iv) Maintenance — the contractor is required to install, maintain, and repair erosion
control measures as needed to prevent sediment from leaving the site.

3) STORMWATER MANAGEMENT PLAN — REDEVELOPMENT
a) Redevelopment Justification — In reviewing the project with a local engineer, John
Parker and the NCDENR the project seem to fit in the category of `redevelopment', This
allows NCDENR some latitude in applying the requirements. The basis of the design is
the reconstruction of the living units in an area that is presently developed for the same
purpose. This project is to upgrade the units to current living standards while leaving as
much of the infrastructure intact. Attached is a synopsis of the current development and
proposed redevelopment impact areas.
b) Stormwater Management Summary — The design of the Stormwater Management
System has been done to adhere to the requirements of NCDENR as much as
practicable. The system uses grassed swales coupled with Extended Dry Detention
Basins for the majority of the treatment system. The outfalls flow from these facilities to
the Camp Lejeune storm drainage system to tributaries of the White Oak River Basin,
The systems provided greatly enhance the quality of the released water over the
present development and provide some peak flow attenuation for downstream facilities.
c) REQUEST FOR ADDITIONAL INFORMATION — Following is the information requested
May 4ih by Linda Lewis:
i) Wetland Confirmation — We have confirmed with the Owner, that wetlands are
not present within the project limits. A statement to that effect has been added to
the Demolition notes, Sheet C-112.
ii) Impervious Breakdown — A completed impervious breakdown is included with the
updated sheets included with the attachments. It is included with Section III, Part
6 of the Stormwater Application.
iii) Access to Facilities for Cleaning. -- Access to the stormwater treatment facilities
is along the pathways established for connectivity between the various housing
areas. These are shown in the grading and drainage plan.
iv) River Basin — We have modified the river basin on the application to read 'White
Oak'.
v) Agent Authorization — An executed authorization form was completed and sent to
NCDENR under separate cover.
vi) Basin #4 Supplement. — A clean copy of the Basin #4 Supplement is included as
an attachment.

vii) Supplement Initials — Supplement forms have been attached with initials and
other comments indicated as appropriate.
viii) Schueler's "Simple Method" — Calculations have been modified to use the
Schueler's "Simple Method". They are included as attachments consisting of
those pages of the application needing modification.
ix) Calculations —The updated calculations include the design requirements and
assumptions. They are included as a portion of the Attachments.
x) Curb Outlet Swales — in an effort to be complete with our submittal, we
misunderstood your requirements and mistakenly added the curb outlet swale
forms. They have been removed per your note,
xi) - Outlet Sizing — The outlet orifices have been adjusted to meet standard sizing.
xii) Basin Locations —The storm drainage basins are indicated on the Grading &
Drainage Plans, C-114 through C-119. A summary of areas and design
information is on Sheet C-006.
xiii) Basin Dimensional Information — In an effort to give you assurances of capacity,
we have included on Sheet C-006 the area required for each contour level of the
basins. In this way, the volume can be verified after construction.
xiv) Perforated Piping — The plans and details have been modified to reflect the
suggest modifications to the inlet piping.

EXTENTED DRY DETENTION BASINS - Design Reguirements and Assumptions
Extended dry detention basins capture the runoff from the 1-year 24-hour storm and
release it over a period of 48 hours or capture the runoff from the 1-inch storm and
allow it to draw over a period of 2 to 5 days.
Detention volumes have been designed for the 1-inch storm using Schueler's simple
method. Computations are included in this Section.
2. Minimum flow length to width ratio of 3:1.
Flow length to width ratio is greater than 3:1 in basins #1 - #5, 2.8:1 in basin #8, and
due to large volume requirements and space limitations, less than 3:1 for
basins #6 and #7. Ratios were determined from the basin dimensions as
shown on the "Stormwater Management Permit Application from Extended Dry
Detention Basin Supplement".
3. Side slopes of the pond should be no steeper than 3:1 horizontal to vertical.
All basin side slopes are 3:1 or greater.
4. Extended detention basins must include a small permanent pool near the outlet orifice
to reduce clogging and keep floating debris away from the outlet.
A one -foot deep "plunge pool" has been shown below the normal basin bottom elevation
near the extended detention orifice at all basins.
5. Cleanout access must be provided that is sufficient for heavy machinery.
Access to all basins will be by the existing street system or by the network of asphalt -
paved paths that cross the site.
6. There must be a drain that will completely empty the basin for cleanout.
The basin will be emptied for cleanout by infiltration through the natural ground, as
stated in the response by the central office staff pertaining to the use of perforated
piping.
7. Any additional peak flow control that the local government requires must be met.
Only basin #6 is providing peak flow control. The 10-year storage elevation is 23.64, or
approximately 1.8' below the lowest finished floor elevation of the adjacent housing.
1007 Stormwater Management Plan Narrative 10 - 13, 6/29/2001

Two Phase Design/Build
Replacement of Family Housing Units
Tarawa Terrace Housing, Marine Corps Base
Camp Lejeune, North Carolina
8. There must be vegetation plan prepared by a NC licensed professional. Consideration
must be given to the grasses specified due to the frequent inundations.
Sheets L-0 through L-6 provide the landscaping and seeding requirements.
9, The basin must be stabilized with 14 days of construction. This might be in the form of
final vegetation, or a temporary means of providing stabilization until the vegetation
becomes established.
Stabilization requirements are shown in the sequence of construction on sheet C-506,
and are shown to be within 14 days of construction.
10. If the basin was used during construction as a sediment basis or trap, then the basin
must be cleaned out, graded, and vegetation within 14 days of the completion of
construction.
Specifications and construction sequence pertaining to conversion from sediment trap
to permanent extended detention ,basin are shown on sheet C-506, Vegetation
requirements are shown to be within 14 days of fine grading.
11. In addition to the detention volume, the design must provide for the sediment storage
that is equal to 20% of the detention volume.
Sediment storage volumes, which are 20% of the detention volumes, are shown on the
extended dry detention basin summary chart on sheet C-006.
12. inlet and outlet channels should be protected from scour during high flows from large
storms. Standard erosion control measures work very well. The Land Quality Section of
the North Carolina Department of Environment and the US Department of Agriculture
Natural Resource Conservation Service (SCS) can provide valuable information on
erosion and sediment control techniques.
Riprap outlet protection has been shown on the storm drain plan sheets C-120 through
C-125, where velocities exceed 4 ff, p. s. Velocities for grassed swales and storm drain
pipes can be found on the drainage area information chart on sheet C-006.

GRASSES SWALES - Design Requirements and Assumptions
Longitudinal slope should be in the range of 2 to 4%. If slope along the flow path
exceeds 4%, then check dams must be installed to reduce the effective slope to below
4%.
Longitudinal swale slopes as designed range from 1 % to 2%. Slopes for swales can be
found on sheet C-006 in the drainage area information chart, in the slope %
column. Drainage area numbers and delineation for each swale can be found
on the grading plan sheets C-114 through C-119.
2. Side slopes should be no greater than 3:1 horizontal to vertical.
All Swale side slopes are designed at 3.1 side slopes for at least the bottom one foot of
swale depth.
3. Maximum runoff velocity should be 2 fps for peak runoff of the 2-year storm.
All swale velocities are less than 2 fps for the 2-year storm, as shown in the drainage
area information chart on sheet C-006 in the velocity/fps column for the 2-year
storm.
4. Design must also non-erosively pass the peak runoff rate from the 10-year storm.
All swale velocities are less than 3 fps for the 10-year storm, as shown in the drainage
area information chart on sheet C-006 in the velocity/fps column for the 10-year storm.
This is below the allowable velocity range for grassed channels of 3.5% - 6.0% as
shown in the North Carolina Erosion and Sediment Control Planning and Design
Mangy appendix table 8.05a.
5, Length of swale shall be at least 100 feet per acre of drainage area.
Swale lengths can be found in the drainage area information chart, sheet C-006, in the
length/total length column. Corresponding drainage area size can be found in
the same chart in either the incremental area or total area column.
6. A vegetation plan shall be prepared in accordance with the recommendations found in
the Erosion and Sediment Control Planning and Design Manual.
Permanent seeding requirements can be found in the sediment and erosion control
detail sheet, C-506. landscape plans are also a part of the project and are identified as
Sheets L-0 through L-6

7. Swales should be stabilized within 14 days of swale construction.
Stabilization requirements are shown in the sequence of construction on sheet C-506,
and are shown to be within 14 days of construction.

Linda.
I appreciate your expediting this application and your
willingness to assist in modify the supplements. I have
attached in the attached Adobe .PDF file five sheets
revising one sheet of calculations and two details on the
plans.
The Dry Basin Calculations Summary Sheet has been modified
to include a column showing the 'El @ Total Required Volume'
to show the difference in elevation between required and
actual provided.
The detail changes are outlined in Extended Dry Detention
Basin Summary on Sheet C-006 [#36 of 841 and Detail 28 - PVC
Cap with Flow Orifice on Sheet C-504 [#71 of 84]. Two
copies of each are enclosed. One is a copy of the detail
you have currently with the red -lined modifications, while
the other is the completed modified detail.
I hope this is sufficient to gain approval. If you need
anything further, please let me know.
Thank You, Dean

Dear Mr. Briggs:
I ran my spreadsheets for each basin after I emailed you.
Each basin
provides the needed volume at the specified "storage
elevation", so I do
not need to revise the storage elevation or surface area
reported on the
supplements. I will still need to revise the provided
volume, since each
basin actually provides the required 1" volume plus the
sediment storage
volume.
The orifice size for all basins, (except #5) is too large.
The drawdown
time is less than 2 days. Please resize to provide a
detention time
06/29/2001 9:00 AM

RE": Tarawa Addendum
between 2 and 5 days. Again, in the interest of time, with
your written
permission, I can make those changes to the supplement after
I recieve
the revised calculations. You will need to revise the table
on Sheet
C-504 and submit 2 copies of that plan sheet.
Thank you. Linda

Subject: Tarawa
Date: Wed, 27 .lun 2001 10:13:22 -0400
From: Linda Lewis <Linda.Lcwis a ncmail.net>
To: Dean Briggs <deanb a briggs-engineering.com>
Dear Mr. Briggs:
I have reviewed the information submitted on June 14, 2001.
1. Please provide the orifice sizing calculations for all eight
basins. I see the calculations for sizing the 10 year storm bypass, but
I need the ones to drawdown the 1" volume in 2-5 days. If these were
submitted in the past, 1 apparently have misplaced them.
2. You have provided a table Labeled as "Dry Basin Calculations
Summary Sheet". That table indicates that the storage elevation for the
basins is well in excess of what is reported on the supplement. For
example, in Basin ##1, the table reports the total required storage
volume (1" plus sediment) as 6730 cubic feet. At elevation 23, you are
providing 10,456 cubic feet, but the supplement lists that only 5608
cubic feet is provided and that the storage elevation is 22.34, not 23.
While the supplement form does not indicate this, the two volumes (1"
and sediment storage) should be added together to arrive at the required
minimum volume to be stored. I will ask Raleigh to make this form
revision as soon as possible. In order to save some time, if you give me
written permission, I can make the needed changes to all the supplements
based on the values presented in the table. I would revise the storage
elevation to the top elevation shown in the table. I would also revise
the volume provided to the volume provided shown in the table. I would
also revise the surface area reported at the storage elevation to the
corresponding surface area shown in the calculations at the top
elevation.
3. The required volumes for Basins 1-5 on sheets 3 of 8 and 4 of 8,
do not include the 20% storage volume, but the somewhat more detailed
calculations for Basins 6, 7 and 8 on sheets 5, 6, 7 and 8 of 8 do
include the sediment volumes. Can you provide similar detailed
calculations for Basins 1-5 as were provided for 6-8?
I believe that once these issues are settled, I will be able to issue
the permit.
Thanks so much for your past and continued cooperation and timely
reponses. Linda

Replacement of Family Housing Units
Tarawa Terrace Housing, Marine Corps Base
Camp Lejeune, North Carolina
1) SITE DESCRIPTION
a) Nature and purpose of construction activity -- to provide 234 new family housing units at
Tarawa Terrace, Camp Lejeune, North Carolina. The work includes the design and
construction of new housing, demolition of existing buildings, site improvements, and
utility services.
i) The site is on the site of an existing housing development. All existing structures
will be demolished and the site cleared prior to construction of the new units.
Major streets and utilities will remain in place. It has been reported by the Owner
that no wetlands are present in the project limits.
ii) The Construction of this project will be accomplished in two phases. Phase I
includes the demolition of existing housing and the construction of 112 new
housing units. Phase II includes the demolition of existing housing and the
construction of 122 new housing units. This erosion and sedimentation control
plan and Stormwater management plan covers the construction phases of the
project.
b) Intended sequence of major activities — major construction activities will occur
approximately in the following order:
i) Site Clearing and Demolition (Phase 1)
ii) Earthwork and Temporary Stabilization (Phase 1)
iii) New Construction and Permanent Stabilization (Phase 1)
iv) Site Clearing and Demolition (Phase 11)
v) Earthwork and Temporary Soil Stabilization (Phase 11)
vi) Infrastructure & Stormwater Facilities Construction and Permanent Soil
Stabilization (Phase 11)
vii) Building Construction
c) Estimated area to be disturbed - 37 acres
d) Description of existing soils types — A soils investigation was performed to identify the
existing soil conditions at the site. Soil samples were classified according to the
"Unified Classification System." The predominant soil types consist of clean sand (SP),
slightly silty sand (SP-SM), clayey sand (SC) and silty sand (SM), with minor amounts of
1007 Stormwater Management Plan Narrative 3 - 18, 5/16/2001

Tarawa Terrace Housing, Marine Corps Base
Camp Lejeune, North Carolina
fat clay (CH) and sandy silt (MH). Groundwater was observed in test borings and hand
augers at a depth of approximately 5.0 to 18.5 feet.
e) Existing vegetation — The existing site is developed with housing units, streets and
parking areas. There are several groups of small trees and lawn areas surrounding the
building units. The demolition phase of the project consists mainly of removing the
existing structures without significant land alteration or vegetation removal.
f) Receiving waters--Stormwater runoff from the Tarawa Terrace development is
collected and routed to the adjacent Northeast Creek located south and east of the
existing development. There is a large natural, vegetated buffer that separates Tarawa
_ . Terrace from the creek that will remain undisturbed by this project. _
g) Site map- See erosion and sedimentation control plans.

Tarawa Terrace Housing, Marine Corps Base
Camp Lejeune, North Carolina
2 EROSION AND SEDIMENT CONTROL
a) Stabilization practices — all denuded areas that will be dormant for extended periods of
time shall be seeded with fast germinating temporary vegetation immediately following
grading. Selection of seed mixture will depend on the time of year when it is applied.
See the North Carolina Erosion and Sediment Control Design Manual for selection of
the seed mixture.
b) Erosion and Sediment Control - Structural Practices
i) Silt Fence — silt fence sediment barriers will be installed down -slope of areas with
minima; grades to filter sediment -laden runoff from sheet -flow, as indicated on the
plans.
ii) Inlet Protection — all storm sewer inlets shall be protected during construction.
Sediment laden water shall be properly filtered before entering the storm sewer
system.
iii) Stabilized Construction Entrance — an approved construction entrance will be
constructed anywhere construction traffic is allowed to leave the site.
iv) Maintenance — the contractor is required to install, maintain, and repair erosion
control measures as needed to prevent sediment from leaving the site.

Camp Lejeune, North Carolina
3) STORMWATER MANAGEMENT PLAN — REDEVELOPMENT
a) Redevelopment Justification — In reviewing the project with a local engineer, John
Parker and the NCDENR the project seem to fit in the category of `redevelopment'. This
allows NCDENR some latitude in applying the requirements. The basis of the design is
the reconstruction of the living units in an area that is presently developed for the same
purpose. This project is to upgrade the units to current living standards while leaving as
much of the infrastructure intact. Attached is a synopsis of the current development and
proposed redevelopment impact areas.
b) Stormwater Management Summary — The design of the Stormwater Management
System has been done to adhere to the requirements of NCDENR as much as
practicable. The system uses grassed swales coupled with Extended Dry Detention
Basins for the majority of the treatment system. The outfalls flow from these facilities to
the Camp Lejeune storm drainage system to tributaries of the White Oak River Basin.
The systems provided greatly enhance the quality of the released water over the
present development and provide some peak flow attenuation for downstream facilities.
c) REQUEST FOR ADDITIONAL INFORMATION — Following is the information requested
May 41h by Linda Lewis:
i) Wetland Confirmation — We have confirmed with the Owner, that wetlands are
not present within the project limits. A statement to that effect has been added to
the Demolition notes, Sheet C-112.
ii) Impervious Breakdown — A completed impervious breakdown is included with the
updated sheets included with the attachments. It is included with Section III, Part
6 of the Stormwater Application.
ii) Access to Facilities for Cleaning. — Access to the stormwater treatment facilities
is along the pathways established for connectivity between the various housing
areas. These are shown in the grading and drainage plan.
iv) River Basin -- We have modified the river basin on the application to read 'White
Oak'.
v) Agent Authorization — An executed authorization form was completed and sent to
NCDENR under separate cover.
vi) Basin #4 Supplement. — A clean copy of the Basin #4 Supplement is included as
an attachment.

vii) Supplement Initials — Supplement forms have been attached with initials and
other comments indicated as appropriate.
viii) Schueler's "Simple Method" — Calculations have been modified to use the
Schueler's Simple Method". They are included as attachments consisting of
those pages of the application needing modification.
ix) Calculations — The updated calculations include the design requirements and
assumptions. They are included as a portion of the Attachments.
x) Curb Outlet Swales — in -an effort to be complete with our submittal, we
misunderstood your requirements and mistakenly added the curb outlet swaie
forms. They have been removed per your note.
xi) Outlet Sizing — The outlet orifices have been adjusted to meet standard sizing.
xii) Basin Locations — The storm drainage basins are indicated on the Grading &
Drainage Plans, C-114 through C-119. A summary of areas and design
information is on Sheet C-006.
xiii) Basin Dimensional Information — In an effort to give you assurances of capacity,
we have included on Sheet C-006 the area required for each contour level of the
basins. In this way, the volume can be verified after construction.
xiv) Perforated Piping —The plans and details have been modified to reflect the
suggest modifications to the inlet piping.

Dear Ms. Lewis:
The purpose of this letter is address each of the comments on your letter dated June 8, 2001. In an
effort you resolve your concerns we have addressed each comment below and have attached (2)
additional copies of submitted information (1) with highlights and direction stickers noting the specific
information you requested. Due to the sensitive nature of this project schedule, I would be pleased
to come to your office and go over the project at your convenience.
We look forward to your review and comments. Following is a synopsis of the responses to your
comments in the order of your letter.
1. Enclosed are application sheets 1, 2, and 3, and pages 1 and 2 of each supplement form as
requested. The supplements have been revised to correct the percentage of impervious
area (formally identified as 100%). The area breakdown section of the application has been
completed. This is the same information submitted in my email of May 22"d
2. The orifice sizes specified on the supplements have been revised from the calculated size to
a standard construction size. Detail #28 on sheet C-504 (dated 5/24/01) shows the size of
the orifices to be constructed while the table "Extended Dry Detention Basin Summary" on
sheet C-006 (dated 5/15/01) identifies the computed orifice size.
A landscape architect, working for the Contractor, with assistance from the Owner's on -staff
landscape professional, completed the landscaping design. Sheet L-0 of the landscape plans
(Planting Notes — Note #3) addresses grass types to be used on the project. A photocopy of
the Planting Notes and the copy of the Turf Specifications are enclosed for your review.
Other non -turf related landscape specifications are available if needed for review. Let me
know if that interest you and I will have them supplied to you.
4. The Owner of the Project has indicated to our Client, the Project Contractor, that no wetlands
are in the project limits. The last sentence of Section 1(a)(i) on page 3 of the Stormwater
Management Plan Narrative (dated 5/16/01) states: "it has been reported by the Owner that
no wetlands are present in the project limits". In addition, a similar note is on Sheet C-112 of
the civil plans. If you need further confirmation, please let me know so we can contract the
Owner for the additional study.

5. There are eight design drainage basins in this project. Each of those eight basins is further
divided into several drainage sub -basins, Those basins and sub -basins are delineated on the
grading and drainage sheets; Sheet C-114 (dated 5/24/01) and sheets C-115 - C-119 (dated
5/14/01). A table, "Extended Dry Detention Basin Summary", on sheet C-006 (dated 5/15/01)
summarizes which sub -basins comprise each of the eight drainage basins [highlighted].
6. Section 40) of the Stormwater Management Plan contains calculations showing the minimum
required storage areas as well as the volumes provided for each basin (Section 4
'ATTACH MENTS'-j) 'Storm Drainage Calculations']. For ease of interpretation and
clarification, a summary sheet is also provided, herewith, that is derived from the calculations
and the table "Extended Dry Detention Basin Summary" on sheet C-006. At no time was a
value of 100 percent impervious used in the drainage calculations. Originally a 'C' (runoff
coefficient) factor was used to correlate total acreage to actual runoff. Due to some
confusion about the meaning of the term "Project Built Upon Area" (Section 111.4 of the
application form) a value of 100 was erroneously entered onto the form. However, the
minimum required volumes are computed correctly using the appropriate value for
impervious area by virtue of the runoff factor. The calculations were revised and the attached
summary sheet using the'Schueier's' method of runoff calculations, peryourrequest. This is
the same set of calculations submitted in my email of May 22"6
7. All basins are irregularly shaped and therefore cannot be precisely dimensioned. The bottom
contour dimensions for each basin are shown in approximation on the supplemental forms
and the required water surface area for each contour interval is specified on sheet C-006.
This will provide adequate quality control during construction to insure adequate volume.
8. Details #26 and #27 on sheet C-504 depict cross section details of the dry basins. These
details show the 20% additional sediment excavation, the outlet structure with orifice, plunge
pool, etc. As requested, the perforated piping has been removed from the detail.

From: Linda Lewis <Linda.I.ewis a ncmail.net>

Dear Mr. Briggs:
I received a response from Central Office staff regarding the use of
perforated piping at the bottom of the dry detention basin. Maintaining
a dry basin is difficult enough without the added worry of a clogged
perforated pipe. The orifice is intended to be the means of achieving
drawdown, and should be located at the required 20% sediment storage
elevation, (i.e., above the bottom) in a small. plunge pool around the
release structure. The plunge pool allows the sediment to accumulate
without overtopping the orifice. The perforated piping is more likely to
clog, resulting in significant potential maintenance problems. The
remaining runoff that accumulates between the orifice and the bottom is
intended to infiltrate through the natural. ground.
If you have any questions, please call or email.

I may be off in interpreting your description of this system, but it seems
to me that rip rapping the bottom of the basin would make maintenance very
difficult. Also, using a perforated collection pipe under the rip rap seems
like it would lend itself to clogging and be a nightmare to maintain. I'm
assuming that they have demonstrated that they are releasing the 1-yr, 24-hr
event. over. 98 hours or are meeting the 2-5 day drawdown requirement for the
1-inch event. However, my interpretation of the design criteria is that the
basin must be vegetated.

Tarawa Terrace Housing Replacement
Onslow County
Dear Cdr. Scanlan:
The Wilmington Regional Office received a Stormwater Management Permit Application for Tarawa
Terrace Housing Replacement on April 18, 2001. 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 delineate all wetlands on site, disturbed or undisturbed, or note on the plans that none
exist.
2. Please complete the impervious area breakdown chart in Section 111, Part 6 of the application,
for each basin.
The cleanout access is not necessarily measured in terms of distance from a street right-of-way,
but in terms of providing sufficient space between structures to Let the needed equipment to the
basin.
4. The river basin for this project is the White Oak. The receiving stream is correctly noted as
Northeast Creel.. I have made this minor change to the application.
Please complete Section VI1 Agent .Authorization. If you don't, I can only deal with you directly
instead of the design engineer. Dean BribYTs, P.E.
6. Pages I and 2 of the supplement for Basin 44 are streaked with black lines and are not usable.
]']ease provide clean originals.
The blanks on the supplements have been check -marked. Please hand -write initials; as
requested.
Al l of the drainage areas on the supplements are 100% impervious, but Section Ill, Part 6 of the
application does not support this. Please correct and revise. We do not require that the basin be
over -designed by using a larger impervious arca, resulting in a larger required volume. Based
Oil 100'% 1111pervious, and us1111-, Schucier's `'Simple Method" calculation as described in the
BM1' document, the basins are providing an avera�lE: volume of 2/3 to '/2 of the required
minimum vcslume. Please redesi�on each basin based on the actual impervious percentage.

----------------------------------------------
Please provide sealed design calculations. which address each design requirement for each
basin, as listed in the BMP document. I need to review the assumptions you made, the
methodology you followed, the equations you used to come up with the design, the minimum
requirements that needed to be met, and what was provided to meet those minimums. .lust
filling in the supplements with the required design elements is not sufficient.
10. Why was a curb outlet supplement provided? Curb outlet swales may only be used for low
density subdivisions. Since Tarawa Terrace is reported as 100% impervious, swales will not
suffice for treatment. If the swales you have listed on the supplement are the ones being used
for additional treatment to achieve the 85% TSS removal, or are interior swales that collect the
runoff and take it to a dry basin, or are swales that transport runoff offsite after the dry basin.
it is not necessary to provide design information, other than what is required for a grassed swale
design in the BMP document.
IL Several of the basins have very odd -sized orifices specified, such as .99", or .93". It is much
easier to specify a standard stock size that will provide the necessary drawdown.
11 Please delineate the drainage area for each basin. Since there are 8 basins proposed; please
provide a plan sheet showing the 8 drainage areas, one per basin.
13. Please specify.. delineate and dimension the bottom contour for basins 1-5 on the storm drain
plan sheets. The bottom contour for Basins 6-8 is specified and delineated, but is not
dimensioned. Please dimension. Do the best you can with odd -shaped basins -overall
dimensions, corners, and radii should be dimensioned. A bearing and distance from an
established structure, such as a building corner, or a parking lot corner is also helpful.
14, The BMP manual does not provide for perforated piping under the bottom of a dry detention
basin as the means to bet runoff into the orifice. You may need to use perforations only on the
top half and a solid bottom, or you may need to delete the perforated piping. I will check with
Central Office staff in Raleigh on this and email you with any response.
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 .tune 4, 2001, 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 compacted application to issue the permit.
