area Runoff associated with this project from Drainage Area 1 has been approved to be
discharged into a stormwater management system permitted under Stormwater
Management Permit No SW8 981023, as described on page 3 of this permit, the Project
Data Sheet The built -upon area allotted to this development by Stormwater Management
Permit No SW8 981023 is 30,360 square feet This project proposes 30,360 square feet
The stormwater system for Drainage Area 2 has been approved for the management of
stormwater runoff as described on page 4 of this permit, the Project Data Sheet The
stormwater control has been designed to handle the runoff from 27,910 square feet of
impervious area This system must be operated with a vegetated filter
3 The tract will be limited to the amount of built -upon area indicated on pages 3 and 4 of
this permit, and per approved plans
4 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
5 The runoff from all built -upon area within the permitted drainage area of this project must
be directed into the permuted stormwater control system A permit modification must be
submitted and approved prior to the construction of additional built -upon area from
outside of the approved drainage area

Section 15 A NCAC 214 1008
Initial in the space provided to indicate the following design requirements have been met and supporting
documentation is attached If the applicant has designated an agent in the Stormwater Management Permit
Application Form, the agent may initial below If a requirement has not been met, attach justification
Applicants Initials
NIA
a System is located 50 feet from class SA waters and 30 feet from other surface waters
b System is located at least 100 feet from water supply wells
c Bottom of system is at least 2 feet above the seasonal high water table
d Bottom of the system is 3 feet above any bedrock or impervious soil horizon
e
Off-line system, runoff in excess of the design volume bypasses the system (bypass detail
provided)
System is designed to draw down the design storage volume to the proposed bottom
elevation under seasonal high water conditions within five days based upon infiltration
through the bottom only (a hydrogeologic evaluation may be required)
g Soils have a minimum hydraulic conductivity of 0 52 inches per hour
h System is not sited on or in fill material or DWQ approval has been obtained
Plans ensure that the installed system will meet design specifications (constructed or
restored) upon initial operation once the project is complete and the entire drainage area is
stabilized
System is sized to take into account the runoff at the ultimate built -out potential from all
surfaces draining to the system, including any off -site drainage
k System is located in a recorded drainage easement for the purposes of operation and
maintenance and has recorded access easements to the nearest public right-of-way
1 System capture and infiltrates the runoff from the first 10 inch of rainfall (1 5 inch event
for areas draining to SA waters)
m Drainage area for the device is less than 5 acres
n A pretreatment device (filter strip, grassed Swale, ediment trap etc ) is provided
o Trench bottom is covered with a layer of clean sand to an average depth of 4 inches
p Sides of the infiltration trench are lined with geotextile fabric
q Rock used is free of fines (washed stone) and has a large void ratio
r Side to bottom area ratio is less than 4 1
Form SWU-107 Version 3 99 Page 2 of 4

s Observation well(s) are provided (case -by -case basis)
t Vegetated filter is provided for overflow (50 feet for SA waters, 30 feet for other waters)
and detail is shown on plans
u A benchmark for checking sediment accumulation is provided 150T CS
IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
1 After every runoff producing rainfall event and at least monthly inspect the bypass/overflow structure for
blockage and deterioration and the infiltration system for erosion, trash accumulation, grass cover, and general
condition
2 Repair eroded areas immediately, re -seed as necessary to maintain adequate vegetative cover, mow vegetated
cover to maintain a maximum height of six -inches, and remove trash as needed
3 Remove accumulated sediment annually or when depth is reduced to 75% of the original design depth Restore
depth to original design depth without over -excavating Over -excavating may cause the required water table
separation to be reduced and may compromise the ability of the system to perform as designed
4 The water level in any monitoring wells will be recorded after a 1 inch rainfall event and at least once a
month Chronic high water table elevations (within 1 foot of the bottom of the system for a period of three
months) shall be reported to DWQ immediately
5 If DWQ determines that the system is failing, the system will immediately be repaired or replaced to original
design specifications if the system cannot be repaired to perform its design function, other stormwater control
devices as allowed by NCAC 2H 1000 must be designed, approved and constructed
b Remove accumulated sediment from the infiltration system annually or when depth in the unit is reduced
to 75% of the original design depth The system shall be restored to the original design depth without
over -excavating Over excavating may cause the required water table separation to be reduced and may
compromise the ability of the system to perform as designed Removed sediment shall be disposed of in an
appropriate manner and shall not be handled in a manner that will adversely impact water quality (i e
stockpiling near a stormwater treatment device or stream, etc )
A benchmark shall be established in the infiltration system The benchmark will document the original
design depth so that accurate sediment accumulation readings can be taken The measuring device used to
determine the depth at the benchmark shall be such that it will give an accurate depth reading and not
readily penetrate into accumulated sediments
When the depth at the benchmark reads 3 0' , the accumulated sediment shall be removed
from the system
See Detail Sheet C5
■ Benchmark Top of drop inlets of infiltration system = 45 5
• Sediment trap 1' below pipe invert = 43 25
• Sediment trap cleanout = 42 5 or T below top of DI grate
