FOR THE
construction, operation and maintenance of one (1) wet detention pond discharging to
Class SA waters in compliance with the provisions of 15A NCAC 2H .1000 and Session
Law 2008-211 (hereafter collectively referred to as the "stormwater rules') the approved
stormwater management plans and specifications and other supporting data as
attached and on file with and approved by the Division of Water Quality and considered
a part of this permit.
This permit shall be effective from the date of issuance until October 25, 2020, and shall
be subject to the following specified conditions and limitations:
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 Section 1.9 on page 3 of this permit. The stormwater
control has been designed to handle the runoff from 29,050 sf of impervious
area.
3. A 50' wide vegetative buffer must be provided and maintained 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.
4. The volume in excess of the design storm from the wet pond must flow overland
through a level spreader and 50-foot vegetated filter strip designed to pass the
peak flow from the 10 year storm in a diffuse, non-eriosive manner.
5. The drainage area(s) will be limited to the amount(s)E of built -upon area indicated
in Sections 1.2 and 1.8 of this permit, and per approved plans. The built -upon area
for the future development is limited to 6,498 squarel feet.

Permit No. SW8 121001
6. All stormwater collection and treatment systems must be located in either
dedicated common areas or recorded easements. The final plats for the project
will be recorded showing all required easements.
7. The runoff from all built -upon area within the permitted drainage area(s) of this
project must be directed into the permitted stormwater control system.
8. The following design criteria have been provided in the wet detention pond and
must be maintained at design condition:
a. Drainage Area, acres: 0.95
Onsite, ft?: 41,500
Offsite, ft2: none
b. Total Impervious Surfaces, ft2: 29,050
Onsite, ft : 29,050
Offsite, ft2: none
C. Design Storm, inches: >3.7
d. Average Pond Design Depth, feet: 3.0
e. TSS removal efficiency: 90%
f. Permanent Pool Elevation, FMS.6: 6.20

n. Fountain Horsepower nla
o. Receiving Stream/River Basin: Eastman Creek 1 White Oak
p. Stream Index Number: 21-24-1
q. Classification of Water Body: "SA, HQW"
9. New discharges to Class SA waters are prohibited, and this project complies by
directing the design storm volume discharged from the wet detention pond to a
secondary BMP in series with the wet pond. The secondary BMP used is a level
spreader and vegetated filter strip capable of providing effective infiltration of the
design storm. Based on the stamped and sealed calculations, the Division is
allowing this design. If, in the future, this design does not meet the intent of the
stormwater rules and is found to cause erosion or has resulted in a discharge to
SA waters, the permit holder will have to install another appropriate design that
provides diffuse flow, prevents erosion and provides effective infiltration.
10. The following design criteria have been provided in the secondary BMP, a level
spreader and vegetated filter strip, which must be maintained at this design
condition:
a. Peak Discharge:
Design Storm, cfs:
0.30
10-yr Storm, cfs:

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 drawn 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.

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 Ioad 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
be repaired immediately.
