Wet Detention 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.
The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided.
This system (check one):
❑ does ® does not incorporate a vegetated filter at the outlet.
This system (check one):
❑ does ® does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
— Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be. watered twice weekly if
needed, until the plants become established (commonly six weeks).
— No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
— Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a dam safety expert should inspect the embankment.
After the `net detention pond is established, it should be inspected 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 should be kept in a known set
location and must 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 Iocation and will be
available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Wet Detention 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.
The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided.
This system (check one):
0 does ® does not incorporate a vegetated filter at the outlet.
This system (check one):
❑ does ® does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
— Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
— No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
— Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected 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 should be kept in a known set
location and must be available upon request.

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
(NI PC,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
be repaired immediately.

Regrade the soil if necessary to
remove the gully, and then
reestablish eroper erosion control.
Study the site to see if a larger
bypass channel is needed (enlarge if
necessary). After this, reestablish
the erosion control material.
Maintain grass at a height of
aeproximately three to six inches.
Regrade the soil if necessary to
remove the gully, anditl en plant a
ground cover and water until it is
established. Provide lime and a
one-time fertilizer application.
Remove the sediment and
restabilize the soil with vegetation if
necessary. Provide lime and a one-
time fertilizer application.
Provide additional irrigation and
fertilizer as needed.
Determine the source of the
problem: soils, hydrology, disease,
etc. Remedy the problem and
replace plants. Provide a one-time
fertilizer application.
Remove vegetation by hand if
possible. If pesticide is used, do not
allow it to get into the receiving
water.

Project Narrative: Knox Landinp_ (136 Homes) CEIVe
October 21, 2103 MAY 1 f 2016
Revised May 2, 2016
BY:
The Proposed Knox Landing neighborhood can be Found on the main side of Marine
Corps Base Camp Lejeune off Highway 24 near Jacksonville, North Carolina in Oltslow
County. The proposed project is the second phase of the existing Knox Landing
neighborhood and calls for the construction of 75 new single family and duplex buildings
(136 housing units in total). The site is located within the White Oak River basin and
drains to Northeast Creek which has a classification as a SC;HQW NSW stream. The
index number for Northeast Creek is 19-16-(3.5). The total area ofdisturbance for the site
will be approximately 47 acres.
This site development was permitted in April 17, 2014, See attached letter from NC
DENIZ— High Density SWS 090925.
The Knox Landing neighborhood will have all newly constructed streets with curb and
gutter along all streets. The proposed project will rely on a discrete stornnvater collection `
system to convey stormwater runoff. Curb inlets and catch basins will direct stormwater
runoFfthrough an underground piping system to a wet detention basin located on -site.
Based on these conditions, the project will qualify as High Density Development and will
be subject to water quality requirements as such.
Water quality requirements are to be satisfied by constructing a new wet detention basin:
The wet detention basin has been designed in accordance with State ol-North Carolina
requirements and will provide drawdown of the 1.5-inch storm within 2-5 days.
'Calculations as well as drainage area exhibits and other requirements will be included in
the stormwater permit application submittal.
Sediment and Erosion Control measures for the site have been designed according to
NCDENR details and specifications. All storm sewer inlets have been specified to
receive either Hardware Cloth and Gravel or Sand Bag Barrier Inlet Protection
throughout the project until Final site stabilization has been attained. In addition to the
inlet protection noted, silt fence and rock check dams will be employed where necessary
in order to prevent sediment from leaving the site and creating erosive soil conditions.
Temporary sediment traps will be constructed during the construction period and
removed once the contributing disturbed drainage areas have been stabilized.
The project cal Is for the proposed construction of 957,600 sq-ft of built upon area and
planned 127,129 sq-ft of future built upon area, divided into three drainage areas. A
portion of the proposed built upon area will drain to the existing wet detention pond that
was designed for the proposed area. The rest of the built upon area will drain to two
proposed wet detention basins, located in the north and south portions of the site.
A portion of the drainage area directed to the north pond is from the proposed Knox
Landing Community Center. This proposed development has been slightly modified,

«�
thus affecting the proposed drainage area and built upon area at this location. The
proposed design of the north pond does not need to be revised as its proposed capacity is
adequate.
As part ofthe planned development a walking trail is planned to be constructed along
Northeast Creek at the southern edge of the site. Parts of this trail do not drain to the wet
detention pond. This section of the trail however, is to be constructed as an elevated,
wooden, open -slotted boardwalk and will not count toward the over built upon area.

please find enclosed a renewed, updated, and re -issued permit and a copy of the renewal application. Please
keep this permit on file at all times. Please note that the renewed, updated, and re -issued permit does not
impose new or different terms; it merely restates some of the previous terms to provide you with a better
understanding of your obligations under the permit.
The renewal and reissuance of this stormwater permit does not imply that the site is currently in compliance
with the terms and conditions of this state stormwater permit. The plans originally approved on October 16,
2009 and most recently revised on April 17, 2014, will remain in full force and effect in accordance with the
regulations set forth in Title 15A NCAC 2H.1000.
This permit is subject to the conditions and limitations as specified therein. Please pay special attention to
the conditions listed in this permit regarding the Operation and Maintenance of the BMP(s), recordation of

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 Section 1.78 of this permit. The runoff from all built -upon area within
the permitted drainage areas of this project must be directed into the permitted
stormwater control measures. The stormwater control measures labeled Drainage
Area 1 (Existing Pond), 2 (North Pond), and 3 (South Pond) have been designed to
handle the runoff from 609,796, 231,649, and 243,284 square feet of built -upon area,
respectively.
3. The drainage areas will be limited to the amounts of built -upon area indicated in
Sections 1.2 and 1.7 of this permit, and per approved plans. The built -upon area for the
future development within Drainage Area 1 (Existing Pond), 2 (North Pond), and 3
(South Pond) is limited to 65,729, 51,400, and 10,000 square feet, respectively.

5. A vegetated filter strip is not required for these ponds as they have been designed for
a 90% total suspended solids removal efficiency. However, the wet detention ponds
associated with DA 2 (North Pond) and DA 3 (South Pond) provide level spreaders to
diffuse the flow into and through the 50' vegetated buffer.
6. All runoff being directed into wetlands shall flow into and through those wetlands at a
non -erosive velocity.
7. The following design criteria have been permitted for the wet detention pond and it
