Dear Mr. Yelverton:
Pat McCrory, Governor
John E. Skvarla, III, Secretary
The Stormwater Permitting Unit received a complete Stormwater Management Permit Application
for the subject project on July 25, 2013. 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. SW1130703, dated
August 23, 2013, 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 August 23, 2021, 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 by filing a written petition with the Office of Administrative
Hearings (OAH). The written petition must conform to Chapter 150B of the North Carolina General
Statutes. Per NCGS 143-215(e) the petition must be filed with the OAH within thirty (30) days of
receipt of this permit. You should contact the OAH with all questions regarding the filing fee (if a
filing fee is required) and/or the details of the filing process at 6714 Mail Service Center, Raleigh,
NC 27699-6714, or via telephone at 919-431-3000, or visit their website at www.NCOAH.com.
Unless such demands are made this permit shall be final and binding.

Inspection Summary:
Laura Herbert (ARO) and Mike Randal[ (RCO) visited the site on 10/3/2014 to determine if construction of the biorention
cell was complete. The project appeared complete and the parking area stabilized with gravel. The biorention cell
appeared to be constructed and completed with vegetation fully established (grass covered). There did not appear to be
any bare areas or erosion in the area of this BMP. Note that is was raining at the time of the inspection. A review of the

IV. PROJECT INFORMATION
1. In the space provided below, briefly summarize how the stormwater runoff will be treated.
Stormwater runoff from the improvements enter a grassy swale which flow to a bioretention cell.
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 PUD Approval 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 II — Post Construction
3. Stormwater runoff from this project drains to the Fren h Broad River basin.
4. Total Property Area: 1.2 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+: 1.2 acres
+ Total project area shall be calculated to exclude thefollowing: the normal pool of impounded structures, the area
between the banks of streams and rivers, the area below the Normal Hi h Water (NHW) line or Mean High Water
(MHW) line, and coastal wetlands landward from the NNW (or MHA line. The resultant project area is used to
calculate overall percent built upon area (BUA). Non -coastal wetlands landward of the NHW (or MHW) line may
be included in the total project area.
8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 = 52 %
9. How many drainage areas does the project have?1 (For high density, count I for each proposed engineered
stormwater BMP. For low density and other projects, use I 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
provided in the same format as below.

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 BMP.
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

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

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

triple shredded hard wood mulch at
a maximum depth of three inches.

needed. Dispose of the spoil in an

triple shredded hard wood mulch at

Dolomitic lime shall be applied as
recommended per the soil test and

Bioretention Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
Iog in a known set Iocation. 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 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.
