I DESIGN STANDARDS
This permit is effective only with respect to the nature and volume of stormwater
described in the application and other supporting data
This stormwater system has been approved for the management of stormwater
runoff as described in Section 1 5 on page 3 of this permit and per the approved
plans The stormwater control has been designed to handle the runoff from a
maximum built -upon area (BUA) of 518,844 square feet of impervious area The
built -upon area reserved for future development is limited to 15,849 square feet
in drainage area #1 and is included in the total BUA listed above
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 such required easements, in accordance with the
approved plans
4 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

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):

incorporate a vegetated filter at the outlet.
incorporate pretreatment other than a forebay.
Important mamtenance 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 fast mitial
fertilization that is required to establish the plants on the vegetated shelf
— Stable groundcover should be mamtamed in the drainage area to reduce the
sediment load to the wet detention basin
— If the basin must be dramed for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be mrmmrzed 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 10 inches (or 15 inches if m 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

PROJECT NARRATIVE
For
Sentry Self Storage Expansion
Brunswick County, North Carolina
July 2016
EROSION AND SEDIMENT CONTROL NARRATIVE
Sentry Storage Is located on NC 211 just west of NC 133, the east most access to Oak Island This
project will build one additional storage facility and provide stormwater treatment for this budding and
associated asphalt pavement The Tax ID number for the property Is 2210064 The total project area
and disturbed area Is 3 42 acres The total parcel area 18 33 acres, 12 42 has been previously
developed with a wet detention pond as a structured BMP
The property generally slopes south with low areas that are soft Excavated material will be used to fill
in low areas grade the project area to create defined high points splitting sheet flow to retain similar
drainage patterns with the exception being Pond 2 intercepting stormwater sheet flow to the west Silt
fence will be installed as required to prevent sediment runoff from stockpile and re -graded disturbed
areas With flat slopes and small disturbed area, temporary silt fencing will be a sufficient erosion
control measure to prevent any sediment from leaving the site A temporary construction entrance will
be installed at the entrance to the to the work area to prevent sediment transport during construction
To prevent sediment from entering the stormwater collection system during construction, block and
gravel inlet protection will be used on the proposed drop inlets These measures shall be inspected
regularly, and the accumulated sediment removed to prevent the conveyance of sediment to any off -
site areas
The primary permanent erosion control measures that will remain after all disturbed areas have been
stabilized and the temporary measures are removed will be permanent grassing A seeding schedule
along with a construction sequence, project description and erosion control notes will be included on
the plans EC E OV/E
JUL 13 2016
STORMWATER MANAGEMENT NARRA IVE
The proposed modification to the current permit includes 79,239 SF of existing Impervious area and
the addition of a 19,000 SF metal storage building with 12,050 SF of associated asphalt concrete
pavement for a total Impervious area of 110,289 SF or 2 5 acres of Impervious area will be routed
through Pond 2

FIRM LICENSE NUMBER C 3014

The proposed project Is located within the Cape Fear River Basin The proposed project drams to the
Jump and Run stream which is classified SC Sw There are no wetlands on the project site
Stormwater from roofs is collected with ram gutters and routed to downspouts that splash onto asphalt
concrete pavement Downspouts are located every 20 feet on the long side (190 feet) of the buildings
A reverse crown of the aisles act as a gutter and routes stormwater to drop inlets and piped to the wet
detention pond, Pond 2 Suitable excavation spoils will be used to fill in low areas and sheet flow
stormwater directly into the main section of Pond 2 The total Pond 2 area is approximately 0 34 acres
(at elevation 35 0 feet) The discharge orifice is a 1-1/2" SCH 40 PVC pipe with an internal diameter
of 1 59 inches This will drawdown the required storage volume in 3 86 days The pond has been
sized to provide 90% TSS removal and does not utilize an existing vegetative filter strip but Is
discharged into a vegetative ditch In the event of a larger than design ram event, an emergency
spillway has been provided at 34 2' MSL The seasonal high water table was observed to be at 32 0'
