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 BMW.
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 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.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Stormwater Treatment Narrative
Miller-Motte College Facility
The City of Jacksonville owns a 6.45 acre tract("Tract 1 Jacksonville Business Park")
located on the corner of Williamsburg Parkway and New Frontier Way (near Western
Boulevard Extension), within the city limits of Jacksonville, NC. The developer, Ray's
Development and Consulting, LLC, wishes to construct a college facility (Miller-Motte) on
a 3.20 acre portion of the tract (to be subdivided into a separate lot). The proposed
college facility will include a single-story building and associated parking, sidewalks &
dumpster pad. Future development in the remaining area of the parcel is expected, but
specific plans are as yet unknown; the proposed stormwater treatment facilities have,
however, been designed to accommodate "future" BUA for that area. (With the
understanding that plan approval & permit revision / modification will be required before
any additional development commences).
The project site is located in the White Oak River basin, and is currently undeveloped.
In general, the site area is flat to gently sloping (0 - 0.4%), and drains to an existing ditch
along the northern property boundary and also to the rear(southern boundary) of the
tract. A small portion of non-coastal wetlands is located to the south -outside the 3.20
acre area of currently proposed development. Runoff from the site drains ultimately to
the southwest into an unnamed tributary of New River(C;NSW)
The proposed development activities are high density (percent impervious > 24
therefore, stormwater treatment facilities are required. The attached Stormwater Plan
includes a wet detention basin located near the northeastern boundary of the site. This
pond has been designed to meet the NPDES Phase II Rules and is designed according
to current BMP Manual Specifications. Runoff generated from impervious surfaces on
site will be diverted to the forebay via sheet drainage, inlets and underground storm
drain pipes. (The off-site drainage area includes one-half of the adjacent (existing) road,
New Frontier Way.) Treated Stormwater will exit the main pond via the outlet structure
and 18" outlet pipe into the existing drainage ditch along that property boundary.

Using Surface Area to Drainage Area Ratio Chart for 90% TSS Removal (copy attached)and
assuming 397 foot pond depth:
SA/DA = 5.80 % (interpolated-Select from Highlighted Cell in SA/DA)
Therefore:

c. Compute Minimum Pond Dimensions
Assume rectangular shape with 3:1 Length (L)to Width (VV) Ratio:
Min Length 199.62foe8
Min Width= 00.54feet
Site conditions, however, dictate irregular shaped pond:
Hydr. Length= feet
so, Hydr. Width (aN 00.0 feet(avg)
Actual L/YV= 3.0 (irregular shape)
3. DETERMINE REQUIRED STORAGE VOLUME
Design Rainfall Depth = inches
Using Schuler"Simple Method":
Rv= 0.05 +0.009(|) where| = percent impervious
Rv= 0.047in/in
Control Vo|umo= Design Rainfall xRvx Drainage Area
Control Volume 10,533CF nay CF

4. DETERMINE REQUIRED STORAGE DEPTH
Assume: O1 side slopes
solving for depth (d) hy trial& error.
U = 1.29
5. DETERMINE ORIFICE SIZE
Control Volume must hn drawn down over a2 day'5 day period.
Using orifice equation,solve for Diameter(D)that results in 3-1/2 day period:
D = (C\/0.V26(h)')o
Where: 8 =(Control Volume / 3.5dayu x 06'400sec/day)
= 0.0V2dt
h= D/3
= 0.43
Solving for D:
D = 1.81 Use " pipo

o.Compute Minimum Pond Dimensions
Assume rectangular shape with 3:1 Length (L)tn Width(VV) Ratio:
Min Length 199.02foo1
Min Width = 00.54feet
Site conditions, however, dictate irregular shaped pond:
Hydr. Length = feet
so, Uydr.Width (m 0O.9 feet(avg)
Actual L8N= 3.0 (irregular shape)
3. DETERMINE REQUIRED STORAGE VOLUME
Design Rainfall Depth= inches
Using Schuler"Simple Method":
Rv= 0.V5 +V.009(|) where| = percent impervious
Rv= 0.647in/in
Control Volume= Design Rainfall xRvx Drainage Area
Control Volume= 10.533CF say CF
Must bo> 18.530 8F
4. DETERMINE REQUIRED STORAGE DEPTH
Assume: %1 side slopes
solving for depth(d)by trial & error:
U = 1.29
5. DETGRM|NE ORIFICE SIZE
Control Volume must be drawn down over a2 day'5 day period.
Using orifice equation, solve for Diameter(D)that results in 3-1/2 day period:
D= (O/0.V25(h)o)»
Where: U= (Control Volume / 3.5 days x06.4VVsec1day)
= 0.062cfs
h = D/3
= 0+43
Solving for D:
D 1,91 Use "pipe

Actual Drawdown with actual drawdown pipe diameter(using orifice equation):
Q= 0.068 cfs
Draw Down Period =

6. SELECT OUTLET STRUCTURE SIZE
Size outlet structure such that depth of Q10 flow< or+to 1 5 Feet
Using Rational Formula (Q=CIA)where:
Cimper=F77777578
Cpery 0.2
Ccum = 0.58
110= 7.78 in/hr
A = 5.26 ac
Q10= 21.89 cfs
Using Francis Formula (Q=3.OLH"')to solve for L such that H = 1.5 Feet
Min L= 3.971 Linear Feet
Use Linear Foot Weir
Use 5 Square Precast Structure
7. DETERMINE 010 STAGE
Q10= 21.89 cfs
From Routing Analysis, H10= 1 25
B. DETERMINE Q100 STAGE(ELEV. OF EMERGENCY SPILLWAY)
Using Rational Formula (Q=CIA)where:
Cimper= 0.8
Cpery= 0.2
Ccum = 0.58
1100 = in/hr
A = 5.26 ac
Q100= 29.04 cfs

Stormwater Treatment Narrative
Miller-Motte College Facility
The City of Jacksonville owns a 6.45 acre tract ("Tract 1 Jacksonville Business Park")
located on the corner of Williamsburg Parkway and New Frontier Way (near Western
Boulevard Extension), within the city limits of Jacksonville, NC. The developer, Ray's
Development and Consulting, LLC, wishes to construct a college facility (Miller-Motte) on
a 3.20 acre portion of the tract (to be subdivided into a separate lot). The proposed
college facility will include a single-story building and associated parking, sidewalks &
dumpster pad. Future development in the remaining area of the parcel is expected, but
specific plans are as yet unknown; the proposed stormwater treatment facilities have,
however, been designed to accommodate "future" BUA for that area. (With the
understanding that plan approval & permit revision / modification will be required before
any additional development commences).
The project site is located in the White Oak River basin, and is currently undeveloped.
In general, the site area is flat to gently sloping (0 - 0.4%), and drains to an existing ditch
along the northern property boundary and also to the rear(southern boundary) of the
tract. A small portion of non-coastal wetlands is located to the south - outside the 3.20
acre area of currently proposed development. Runoff from the site drains ultimately to
the southwest into an unnamed tributary of New River (C;NSW)
The proposed development activities are high density (percent impervious > 24 %);
therefore, stormwater treatment facilities are required. The attached Stormwater Plan
includes a wet detention basin located near the northeastern boundary of the site. This
pond has been designed to meet the NPDES Phase II Rules and is designed according
to current BMP Manual Specifications. Runoff generated from impervious surfaces on
site will be diverted to the forebay via sheet drainage, inlets and underground storm
drain pipes. (The off-site drainage area includes one-half of the adjacent (existing) road,
New Frontier Way.) Treated Stormwater will exit the main pond via the outlet structure
and 18" outlet pipe into the existing drainage ditch along that property boundary.

Stormwater Treatment Narrative
Miller-Motte College Facility
The City of Jacksonville owns a 6.45 acre tract ("Tract 1 Jacksonville Business Park")
located on the corner of Williamsburg Parkway and New Frontier Way (near Western
Boulevard Extension), within the city limits of Jacksonville, NC. The developer, Ray's
Development and Consulting, LLC, wishes to construct a college facility (Miller-Motte) on
a 3.20 acre portion of the tract (to be subdivided into a separate lot). The proposed
college facility will include a single-story building and associated parking, sidewalks &
dumpster pad. Future development in the remaining area of the parcel is expected, but
specific plans are as yet unknown; the proposed stormwater treatment facilities have,
however, been designed to accommodate "future" BUA for that area. (With the
understanding that plan approval & permit revision / modification will be required before
any additional development commences).
The project site is located in the White Oak River basin, and is currently undeveloped.
In general, the site area is flat to gently sloping (0- 0.4%), and drains to an existing ditch
along the northern property boundary and also to the rear(southern boundary) of the
tract. A small portion of non-coastal wetlands is located to the south - outside the 3.20
acre area of currently proposed development. Runoff from the site drains ultimately to
the southwest into an unnamed tributary of New River (C;NSW)
The proposed development activities are high density (percent impervious > 24 %);
therefore, stormwater treatment facilities are required. The attached Stormwater Plan
includes a wet detention basin located near the northeastern boundary of the site. This
pond has been designed to meet the NPDES Phase II Rules and is designed according
to current BMP Manual Specifications. Runoff generated from impervious surfaces on
site will be diverted to the forebay via sheet drainage, inlets and underground storm.
drain pipes. Treated S4ormwater will exit the main pond via the outlet structure and 18"
outlet pipe into the existing drainage ditch along that property boundary.
