POST -CONSTRUCTION STORMWATER MANAGEMENT PERMIT
HIGH DENSITY DEVELOPMENT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as
amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Camp Lejeune USMarine Corps Base
P-1357 Child Development Center Courthouse Bay
Intersection of Highway 172 and Marines Road, Camp Lejeune, Onslow County
FOR THE
construction, operation and maintenance of three (3) bioretention basins, two (2) infiltration basins,
permeable pavement, a level spreader and vegetated filter strip system in compliance with the
provisions of Session Law 2008-211 and 15A NCAC 2H .1000 (hereafter jointly and severally referred
to as the "stormwater rules') and ... as outlined in the application, approved stormwater management
plans, supplement, calculations, operation and maintenance agreement, recorded documents,
specifications, and other supporting data (the "approved plans and specifications") as attached and/or
on file with and approved by the Division of Energy, Mineral and Land Resources (the "Division" or
"DEMLR"). The project shall be constructed, operated and maintained in accordance with these
approved plans and specifications. The approved plans and specifications are incorporated by
reference and are enforceable part of this permit.
This permit shall be effective from the date of issuance until December 31, 2029 and shall be subject
to the following specified conditions and limitations. The permit issued shall continue in force and
effect until the permittee files a request with the Division for a permit modification, transfer, renewal, or
rescission; however, these actions do not stay any condition. The issuance of this permit does not
prohibit the Director from reopening and modifying the permit, revoking and reissuing the permit, or
terminating the permit for cause as allowed by the laws, rules, and regulations contained in Title 15A
NCAC 2H.1000 and NCGS 143-215.1 et.al.
I. DESIGN STANDARDS
1. This permit is effective only with respect to the nature and volume of stormwater described in
the application and other supporting data.
2. This stormwater system has been approved for the management of stormwater runoff as
described in Sections 1.6 and 1.7 of this permit. The bioretention cells in DA-1, DA-2 and DA-3
have been designed to handle the runoff from 22,934 ft2, 20,671 ft2, and 1,770 ft2, of built -upon
area respectively. The infiltration basins in DA-4 and DA-5 have been designed to handle the
runoff from 60,621 ft2, and 43,086 ft2 of built -upon area, respectively. Infiltration Basin DA-4 is
designed to handle the 10 year storm without discharging, per Section 16.3.9 of the
07/23/2009 BMP Manual, therefore a vegetated filter is not required for that basin. A level
spreader and vegetated filter are required for the infiltration basin in DA-5.
3. The drainage area limits for each BMP shall not exceed what is shown on the approved
drainage area plan and listed in Sections 1.6 and 1.7 of this permit. Each BMP shall treat no
more than that amount of built -upon area indicated in Sections 1.2, 1.6 and 1.7 of this permit,
and per the application documents and the approved plans. The runoff from all permitted built -
upon area within each BMP drainage area shall be directed to the appropriate BMP.

Permit No. SW8 100502
4. The project shall provide a 50' wide vegetated buffer adjacent surface waters, measured
horizontally from and perpendicular to the normal pool of impounded structures, the top of
bank of both sides of streams and rivers, and the mean high water line of tidal waters.
5. The bioretention cells in DA-1, DA-2 and DA-3 do not provide sufficient volume to completely
handle the 3.67" design storm, therefore, they all overflow into the infiltration basin in DA-4,
which has been designed to accommodate the runoff from DA's 1-4, inclusive, less the total
volume stored in the bioretention basins.
6. The following design criteria have been met and provided in the 3 bioretention cells and must

Bioretention Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important operation and maintenance procedures:
— Immediately after the bioretention cell is established, the plants will be watered
twice weekly if needed until the plants become established (commonly six
weeks).
— Snow, mulch or any other material will NEVER be piled on the surface of the
bioretention cell.
— Heavy equipment will NEVER be driven over the bioretention cell.
Special care will betaken to prevent sediment from entering the bioretention cell.
— Once a year, a soil test of the soil media will be conducted.
After the bioretention cell is established, I will inspect it once a month and within 24
hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Bioretention Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important operation and maintenance procedures:
— Immediately after the bioretention cell is established, the plants will be watered
twice weekly if needed until the plants become established (commonly six
weeks).
— Snow, mulch or any other material will NEVER be piled on the surface of the
bioretention cell.
— Heavy equipment will NEVER be driven over the bioretention cell.
— Special care will be taken to prevent sediment from entering the bioretention cell.
— Once a year, a soil test of the soil media will be conducted.
After the bioretention cell is established, I will inspect it once a month and within 24
hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Infiltration Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
— The drainage area will be carefully managed to reduce the sediment load to the
infiltration basin.
— Immediately after the infiltration basin is established, the vegetation will be
watered twice weekly if needed until the plants become established (commonly
six weeks).
— No portion of the infiltration basin will be fertilized after the initial fertilization
that is required to establish the vegetation.
— The vegetation in and around the basin will be maintained at a height of
approximately six inches.
After the infiltration basin is established, it will be inspected once a quarter and within
24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall

Infiltration Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
— The drainage area will be carefully managed to reduce the sediment load to the
infiltration basin.
— Immediately after the infiltration basin is established, the vegetation will be
watered twice weekly if needed until the plants become established (commonly
six weeks).
— No portion of the infiltration basin will be fertilized after the initial fertilization
that is required to establish the vegetation.
— The vegetation mi and around the basin will be maintained at a height of
approximately six inches.
After the infiltration basin is established, it will be inspected once a quarter and within
24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
— Immediately after the filter strip is established, any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
— Once a year, the filter strip will be reseeded to maintain a dense growth of
vegetation
— Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
— Two to three times a year, grass filter strips will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum pollutant
removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and
may be allowed to grow as tall as 12 inches depending on aesthetic requirements
(NIPC, 1993). Forested filter strips do not require this type of maintenance.
— Once a year, the soil will be aerated if necessary.
— Once a year, soil pH will be tested and lime will be added if necessary.
After the filter strip is established, it will be inspected quarterly and within 24 hours
after every storm event greater than 1.0 inch (or 1.5 inches if in a Coastal County).
Records of operation and maintenance will be kept in a known set location and will be
available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall

Project proposes a 1,000 sq. ft. permeable concrete driveway with a 6" gravel base. u
Managed grass factor = 0.6
1000 x 0.6 = 600 square feet is counted as managed grass.
1000 - 600 = 400 square feet is counted as built -upon area.

Example #2
Project is a high density commercial site with a 5,000 square foot parking lot.
Project is within 1/2 mile of and draining to SA waters. An infiltration system is proposed.
The packing lot will handle <100 cars per day and is a flexible pavement with a 4" gravel base.
Managed grass factor is one half of 0.4. = 0.2
5000 x 0.2 = 1000 square feet is counted as managed grass.
5000 - 1000 = 4,000 square is counted as impervious.
The total BUA used to calculate the minimum volume draining to the
infiltration system can be reduced by 1,000 square feet.

Permeable Pavement Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important operation and maintenance procedures:
— Stable groundcover will be maintained in the drainage area to reduce the sediment
load to the permeable pavement.
— The area around the perimeter of the permeable pavement will be stabilized and
mowed, with clippings removed.
— Any weeds that grow in the permeable pavement will be sprayed with pesticide
immediately. Weeds will not be pulled, since this could damage the fill media.
— Once a year, the permeable pavement surface will be vacuum swept.
— At no time shall wet sweeping (moistening followed by sweeping) be allowed as a
means of maintenance.
— There shall be no repair or treatment of Permeable Pavement surfaces with other
types of pavement surfaces. All repairs to Permeable Pavement surfaces must be
accomplished utilizing permeable pavement which meets the original pavement
specifications.
— Concentrated runoff from roof drains, piping, swales or other point sources,
directly onto the permeable pavement surface shall not be allowed. These areas
must be diverted away from the permeable pavement.
Initial Inspection: Permeable Pavements shall be inspected monthly for the first three
months for the following:

Example #1
Project is a lot with a maximum allowed BUA of 5,000 sq. ft. that drains to class SC waters.
Project proposes a 1,000 sq. ft. permeable concrete driveway with a 6" gravel base.
Managed grass factor = 0.6
1000 x 0.6 = 600 square feet is counted as managed grass.
1000 - 600 = 400 square feet is counted as built -upon area.
5000 - 400 = 4,600 square feet available for house and other BUA.
Example #2
Project is a high density commercial site with a 5,000 square foot parking lot.
Project is within 1/2 mile of and draining to SA waters. An infiltration system is proposed.
The parking lot will handle <100 cars per day and is a flexible pavement with a 4" gravel base.
Managed grass factor is one half of 0.4. = 0.2
5000 x 0.2 = 1000 square feet is counted as managed grass.
5000 - 1000 = 4,000 square is counted as impervious.
The total BUA used to calculate the minimum volume draining to the
infiltration system can be reduced by 1,000 square feet.

Permeable Pavement Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important operation and maintenance procedures:
— Stable groundcover will be maintained in the drainage area to reduce the sediment
load to the permeable pavement.
— The area around the perimeter of the permeable pavement will be stabilized and
mowed, with clippings removed.
— Any weeds that grow in the permeable pavement will be sprayed with pesticide
immediately. Weeds will not be pulled, since this could damage the fill media.
— Once a year, the permeable pavement surface will be vacuum swept.
— At no time shall wet sweeping (moistening followed by sweeping) be allowed as a
means of maintenance.
— There shall be no repair or treatment of Permeable Pavement surfaces with other
types of pavement surfaces. All repairs to Permeable Pavement surfaces must be
accomplished utilizing permeable pavement which meets the original pavement
specifications.
— Concentrated runoff from roof drains, piping, swales or other point sources,
directly onto the permeable pavement surface shall not be allowed. These areas
must be diverted away from the permeable pavement.
Initial Inspection: Permeable Pavements shall be inspected monthly for the first three
months for the following:
