Dear Mr. Noel:
Dee Freeman
Secretary
4� f.
�! APR - L�
The Stormwater Permitting Unit received a complete Stormwater Management Permit Application for K-FLEX
Warehouse Addition on February 29, 2012. Staff review of the plans and specifications has determined that
the project, as proposed, will comply with the Stormwater Regulations set forth in Title 15A NCAC 2H.1000 and
Session Law 2006-246. We are forwarding Permit No. SW5120202, dated March 1, 2012, for the construction,
operation and maintenance of the subject project and the stormwater BMPs.
This permit shall be effective from the date of issuance until March 1, 2020 and shall be subject to the
conditions and limitations as specified therein, and does not supersede any other agency permit that may be
required. Please pay special attention to the conditions listed in this permit regarding the Operation and
Maintenance of the BMP(s), recordation of deed restrictions, procedures for changes of ownership,
transferring the permit, and renewing the permit. Failure to establish an adequate system for operation and
maintenance of the stormwater management system, to record deed restrictions, to follow the procedures for
transfer of the permit, or to renew the permit, will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to
request an adjudicatory hearing upon written request within thirty (30) days following receipt of this permit.
This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina
General Statutes, and filed with the Office of Administrative Hearings, P.Q. Drawer 27447, Raleigh, NC 27611-
7447. Unless such demands are made this permit shall be final and binding.
This project will be kept on file at the Raleigh Regional Office. If you have any questions, or need additional
information concerning this matter, please contact Robert Patterson at [phone]; or
[e-mail].
Sincerely,

IV. PROJECT INFORMATION
1. In the space provided below, briefly summarize how the stormwater runoff will be treated.
The areas of proposed impervious are collected and routed to new Crass -line Bio-Retention„Basins. In Basin 1,
the in -flow is stilled through use of a concrete lined forebay, in Basin 2 the run-off is sheet flow over land and
velocity is disabated and possible sediments are removed via an 8" gravel stripe with 5' of grass sod filter.
2. a. If claiming vested rights, identify the supporting documents provided and the date they were approved:
❑ Approval of a Site Specific Development Plan or PUDApproval Date:
❑ Valid Building Permit Issued Date:
❑ Other: Date:
b. If claiming vested rights, identify the regulation(s) the project has been designed in accordance with:
❑ Coastal SW — 1995 ❑ Ph 11— Post Construction
3. Stormwater runoff from this project drains to the Neuse River basin.
4. Total Property Area: 15,01. acres
5. Total Coastal Wetlands Area: 0 acres
6. Total Surface Water Area: 0 acres
7. Total Property Area (4) —Total Coastal Wetlands Area (5) —Total Surface Water Area (6) = Total Project Area':
15.01 acres
Total project area shall be calculated to exclude the following: the normal pool of inipounded structures, the area
between the batiks of streams and rivers, the area below the �lorrnal High Water (NNW) lure or Mean High Water
(MHW) line, and coastal wetlands landward from the NHW (or MHW) line. The resultant project area is used to
calculate overall percent built upon area (BLIA). Non -coastal wetlands landward of the NHW or MHW) line txay be
included in the total project area.
8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 = 43.8
9. How many drainage areas does the project have?2 (For high density, count 1 for each proposed engineered
storrnwater BMR For lozo density and other projects, use 7 for the whole property area)
10. Complete the following information for each drainage area identified in Project Information item 9. If there
are more than four drainage areas in the project, attach an additional sheet with the information for each area

Bioretention 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 BMI'.
Important operation and maintenance procedures:
— Immediately after the bioretention cell is established, the plants will be watered
twice weekly if needed until the plants become established (commonly six
weeks).
— Snow, mulch or any other material will NEVER be piled on the surface of the
bioretention cell.
— Heavy equipment will NEVER be driven over the bioretention cell.
— Special care will be taken to prevent sediment from entering the bioretention cell.
— Once a year, a soil test of the soil media will be conducted.
After the bioretention cell is established, I will inspect it 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 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.

restabilize the pretreatment area.
Provide additional erosion

Remove the weeds, preferably by

Prune according to best professional
practices.
Determine the source of the
problem: soils, hydrology, disease,
etc. Remedy the problem and
replace plants. Provide a one-time
fertilizer application to establish the
ground cover if a soil test indicates
it is necessary.
Remove tree stake/wires (which
can kill the tree if not removed).
Spot mulch if there are only random
void areas. Replace whole mulch
layer if necessary. Remove the
remaining much and replace with
triple shredded hard wood mulch at
a maximum depth of three inches.
Determine the extent of the clogging

needed. Dispose of the spoi l in an

Search for the source of the

BMP element:
The pretreatment area
The bioretention cell:
vegetation
The bioretention cell:
soils and mulch
Potential problems:
Flow is bypassing
pretreatment area and/or
gullies have formed.
Sediment has accumulated to
a depth greater than three
inches.
Erosion has occurred
Weeds are present.
Best professional practices
show that pruning is needed
to maintain optimal plant
health.
Plants are dead, diseased or
dying.
Tree stakes/wires are present
six months after planting.
Mulch is breaking down or
has floated away.
Soils and/or mulch are
clogged with sediment.
An annual soil test shows that
pH has dropped or heavy
metals have accumulated in
the soil media.
How I will remediate the problem:
Regrade if necessary to route all
flow to the pretreatment area.
Restabilize the area after grading.
Search for the source of the
sediment and remedy the problem if
possible. Remove the sediment and
restabilize the pretreatment area.
Provide additional erosion
protection such as reinforced turf
matting or riprap if needed to
prevent future erosion problems.
Remove the weeds, preferably by
hand.
Prune according to best professional
practices.
Determine the source of the
problem: soils, hydrology, disease,
etc. Remedy the problem and
replace plants. Provide a one-time
fertilizer application to establish the
ground cover if a soil test indicates
it is necessary.
Remove tree stake/wires (which
can kill the tree if not removed).
Spot mulch if there are only random
void areas. Replace whole mulch
layer if necessary. Remove the
remaining much and replace with
triple shredded hard wood mulch at
a maximum depth of three inches.
Determine the extent of the clogging
- remove and replace either just the
top layers or the entire media as
needed. Dispose of the spoil in an
appropriate off -site location. Use
triple shredded hard wood mulch at
a maximum depth of three inches.
Search for the source of the
sediment and remedy the problem if
possible.
Dolomitic lime shall be applied as
recommended per the soil test and
toxic soils shall be removed,
disposed of properly and replaced
with new planting media.
