STATE OF NORTH CAROLINA
DEPARTMENT OF ENVIRONMENTAL QUALITY
DIVISION OF'ENERGY, MINERAL AND LAND RESOURCES
STATE STORMWATER MANAGEMENT PERMIT
DEVELOPMENT WITH AREAS OF BOTH HIGH DENSITY AND LOW DENSITY
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North
Carolina as amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
UNC Wilmington
Hurst Hamilton Parking Lots
Hurst Drive and Wagoner Drive, Wilmington, New Hanover County
FOR THE
construction, operation and maintenance of one (1) wet pond ('stormwater control measures'' or
`SCMs") as well as one (1) area of 24% low density and one (1) area of redevelopment in compliance
with the provisions of Title 15A NCAC 2H .1000 effective January 1, 2017 (the "stormwater rules") and
the approved stormwater management plans, application, supplement(s), specifications, and other
supporting data (the "approved plans and specifications'') as attached and/or on file with and
approved by the Division of Energy, Mineral and Land Resources (the "Division" or "DEMLR") and
considered an enforceable part of this permit.
This permit shall be effective from the date of issuance until June 16, 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 management and volume of stormwater
described in the approved plans and specifications. The maximum amount of built -upon area
(BUA) allowed for the entire project is 677,828 square feet.
2. The redevelopment portion of this project is exempt from State Stormwater permitting
requirements under the following conditions: 1) The project must be constructed as shown on
the plans submitted to this Office; 2) the proposed redeveloped BUA of 14,555 square feet does
not exceed the existing BUA of 14,760 square feet; and 3) The proposed stormwater control
(vegetated sheet flow and a vegetated channel) provides equal protection of surface waters as
the existing stormwater control (vegetated sheet flow and a vegetated channel).
3. The low density area must not exceed 24% per the requirements of the stormwater rules. Within
this low density area, this permit covers the construction of a total of 25,145 square feet of BUA,
which includes 18.253 square feet of proposed BUA and 6,892 square feet of previously
permitted BUA. This low density area excludes 22,215 square feet of existing built -upon area in
accordance with 15A NCAC 02H.1003(1)(b).
4. The low density area, Drainage Area 2, has maximized dispersed flow of stormwater runoff
through vegetated areas and minimized the channelization of flow. Stormwater runoff that could
not be released as dispersed flow may be transported by vegetated conveyances with minimum
side slopes of 3:1 (H:V) designed to not erode during the peak flow from the 10-year storm event
as defined in the stormwater rules and approved by the Division.
Page 1 of 5

State Stormwater Management
Permit No. SW8 060530
5. Within the low density area; Drainage Area 2, no piping shall be allowed except those minimum
amounts necessary to direct stormwater runoff beneath a BUA such as a road or driveway when
it cannot be avoided.
6. The drainage area for the on -site stormwater system will be limited to the amount of built -upon
area indicated in this permit and the approved plans and specifications. The runoff from all built -
upon area within the permitted drainage area of this project must be directed into the permitted
stormwater control measure. The stormwater control measure has been designed using the
runoff treatment method to handle the runoff from 638.128 square feet of impervious area which
includes 29,000 square feet of impervious area for future allocation.
A 50-foot wide vegetative setback must be provided and maintained adjacent to all surface
waters. measured horizontally from the normal pool elevation of impounded structures, from the
top of bank of each side of streams or rivers; and from the mean high waterline of tidal waters,
perpendicular to the shoreline in accordance with the stormwater rules and the approved plans
and specifications. Within the low density area all stormwater runoff, including roof drains; shall
be released as dispersed flow no closer than at the edge of the vegetated setback and at no
time shall stormwater runoff be piped into or through the setback.
The stormwater control measure is permitted based on the design criteria presented in the
sealed, signed and dated supplement and as shown in the approved plans and specifications.
These stormwater control measure must be provided and maintained at the design condition.
The approved supplement is incorporated by reference into this permit.
9. The peak flow from the 10-year storm event shall not cause erosion downslope of the
stormwater outlet discharge point.
10. Decorative spray fountains will be allowed in the stormwater treatment system if documentation
is provided demonstrating that the proposed fountain will not cause resuspension of sediment
within the pond or cause erosion of the pond side slopes.
11. When using a wet pond for irrigation, it is recommended that some water be maintained in the
permanent pool; the vegetated shelf is planted with appropriate species that can handle
fluctuating conditions, and human health issues are addressed.
12. The SCM landscape planting plan shown in the approved plans shall be followed in its entirety
during construction. After the plants are established, the operation and maintenance agreement
must be followed.
13. The stormwater system is permitted as a variation to the requirements under Title 15A NCAC
20H.1003(6) as the forebays (existing and proposed) exceed the 15-20% minimum design
criteria. The proposed system provides equal or better stormwater control and equal or better
protection of surface waters. If the proposed system is found to not meet the intent of the
stormwater rules; the stormwater control measure will have to meet the requirements of the
stormwater rule or another alternative must be proposed and a permit modification will be
required.
II. SCHEDULE OF COMPLIANCE
1. The project and SCM shall be constructed, operated and maintained in accordance with the
conditions of this permit and the approved plans and specifications.
2. The on -site stormwater system shall be entirely constructed, vegetated, and operational prior to
the construction of any development within the drainage area, per the approved plans and
specifications.
3. During construction, erosion shall be kept to a minimum and any eroded areas of the on -site
stormwater system will be repaired immediately. If the stormwater system is used as an Erosion
Control device, it must be restored to design condition prior to operation as a stormwater
treatment device, and prior to occupancy of the facility.

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.
'rhe 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 drain 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.

between the banks of streams and rivers, the area below the Normal High Water (NHW) line 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 (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 = 50.07
9. How many drainage areas does the project have?l (For high densihj, count 1 for each proposed engineered
stormwater BMP. For low densihj and other projects, use 1 for the whole properhj area)

ADDITIONAL INFORMATION
Please use this space to provide any additional information about this wet pond that you think is relevant to the review:
It should be noted that this SCM was previously constructed and therefore is undergoing modification to accomdate proposed development and meet current design standards. As such, the existing dam embankment will remain with modified
grading only occuring internally. The forebay percentage exceeds the volume requirement for forebay requirement stated in the MDCs, which is primarily due to the volume contributed by the existing forebay across Hurst Drive that is remaining
unaltered as a pan of this project.

Footnotes:
I . When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
2. In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90%TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90%TSS removal.
II. REQUIRED ITEMS CHECKLIST
The following checklist outlines design requirements per the Stormwater Best Management Practices Manual
(N.C. Department of Environment, Health and Natural Resources, February 1999) and Administrative Code
Section: 15 A NCAC 2H .1008.

111. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
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
This system (check one) ❑ does
Form SWU-102 Version 3.99
® does not incorporate a vegetated filter at the outlet.
® does not incorporate pretreatment other than a forebay.
Page 2 of 4

Maintenance activities shall be performed as follows:
After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of temporary pool occurs
within 2 to 5 days as designed.
2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to
maintain proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of
in an appropriate manner and shall be handled in a manner that will not adversely impact water quality (i.e.
stockpiling near a wet detention basin or stream, etc.)
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 5.62 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 3.75 feet in the forebay, the sediment shall be removed.

Required Items to be checked for this certification to be considered complete are listed below.
Please note any deviations from approved plans and specifications here:
1. During construction, under SWMF #2 a brown clayey sand layer was encountered and determined to be
unsuitable for infiltration. Per Geotechnical Engineer recommendation, the layer encountered was undercut
18-inches and replaced with a clean sand (Soil Class SP,SW). This allowed 12-inches of in -situ soil
between the fill and seasonal high water table, with a total of 30-inches between infiltration subgrade and
SHWi (Approved by Christine Hall of NCDEQ on 4124/17, prior to installation). As -built infiltration testing
was performed to confirm infiltration rates.
