POST-CONSTRUCTION STORMWATER MANAGEMENT PERMIT
HIGH DENSITY DEVELOPMENT
In compliance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as
amended, and other applicable Laws, Rules, and Regulations promulgated and adopted by the North
Carolina Environmental Management Commission, including 15A NCAC 02H.1000 amended on
January 1, 2017 (2017 Rules) (the "stormwater rules"),
PERMISSION IS HEREBY GRANTED TO
WLM PROPCO, LLC
GoDog Pet Hospitality Services Building
8130 Market Street, Wilmington, New Hanover County
FOR THE
construction, management, operation and maintenance of built-upon area (BUA) for one (1) wet
detention pond and one (1) level spreader-vegetated filter strip ("stormwater control measures" or
"SCMs") discharging to Class SA-HQW waters as outlined in the application, approved stormwater
management plans, supplement, calculations, operation and maintenance agreement, recorded
documents, 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"). The project shall be constructed, operated and maintained in accordance
with these approved plans and specifications. The approved plans and specifications are
incorporated by reference and are enforceable part of this permit.
This permit shall be effective from the date of issuance until June 9, 2030 and shall be subject to the
following specified conditions and limitations. The permit issued shall continue in force and effect until
the permittee files a request with the Division for a permit modification, transfer, renewal, or
rescission; however, these actions do not stay any condition. The issuance of this permit does not
prohibit the Director from reopening and modifying the permit, revoking and reissuing the permit, or
terminating the permit for cause as allowed by the laws, rules, and regulations contained in Title 15A
NCAC 2H.1000 and NCGS 143-215.1 et.al.
1. BUA REQUIREMENTS. The maximum amount of BUA allowed for the entire project is 87,120
square feet. The runoff from all BUA within the permitted high density drainage area of this
project must be directed into the permitted SCMs. The BUA requirements and allocations for
this project are as follows:
a. SCM BUA LIMITS. The SCMs have been designed to handle the runoff from 87,120 square
feet of BUA within the delineated drainage area. The BUA for the future development is
limited to 5,796 square feet.
2. PERVIOUS AREA IMPROVEMENTS. At this time, none of the pervious area improvements
listed in G.S. 143-214.7(b2) or the Stormwater Design Manual have been proposed for this
project. Pervious area improvements will be allowed in this project if documentation is provided
demonstrating those improvements meet the requirements of the stormwater rule.

Permit No. SW 211201
3. SCM REQUIREMENTS. The SCM requirements for this project are as follows:
a. SCM DESIGN. The SCMs are permitted based on the design criteria presented in the
sealed, signed and dated supplements and as shown in the approved plans and
specifications. These SCMs must be provided and maintained at the design condition.
b. SCM DESIGN FOR SA WATER. The SCMs provide runoff treatment for the difference
between the pre- and post-development runoff volumes for the one-year, 24-hour storm
event and have demonstrated that it is not feasible to meet the minimum design criteria for
an infiltration system. The stormwater is filtered through a minimum of 18 inches of sand
prior to discharge. The discharge is directed to a level spreader—filter strip, and the excess
runoff is released at a non-erosive velocity at the edge of the vegetated setback or to an
existing stormwater drainage system.
c. PLANTING PLAN. 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.
d. FOUNTAINS. At this time, a decorative spray fountain has not been proposed within the wet
pond. Decorative spray fountains will be allowed in the wet pond 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.
e. IRRIGATION. If the wet pond is to be used 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.
A STORMWATER OUTLETS. The peak flow from the 10-year storm event shall not cause
erosion downslope of the discharge point.
5. VEGETATED SETBACKS. A 50-foot-wide vegetative setback must be provided and maintained
in grass or other vegetation adjacent to all surface waters as shown on the approved plans. The
setback is 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.
a. BUA IN THE VEGETATED SETBACK. BUA may not be added to the vegetated setback
except as shown on the approved plans.
b. RELEASE OF STORMWATER NOT TREATED IN AN SCM. Stormwater that is not treated
in an SCM must be released at the edge of the vegetated setback and allowed to flow
through the setback as dispersed flow.
6. RECORDED DOCUMENT REQUIREMENTS. The stormwater rules require the following
documents to be recorded with the Office of the Register of Deeds:
a. EASEMENTS. All SCMs, stormwater collection systems, vegetated conveyances, and
maintenance access located on property owned by other persons or entities must be located
in permanent recorded easements or drainage easements as shown on the approved plans.
b. OPERATION AND MAINTENANCE AGREEMENT. The operation and maintenance
agreement must be recorded with the Office of the Register of Deeds.
c. FINAL PLATS. If a final plat is recorded, it must reference the operation and maintenance
agreement and must also show all public rights-of-way, dedicated common areas, and/or
permanent drainage easements, in accordance with the approved plans.
d. DEED RESTRICTIONS AND PROTECTIVE COVENANTS. The permittee shall record deed
restrictions and protective covenants prior to the issuance of a certificate of occupancy to
ensure the permit conditions and the approved plans and specifications are maintained in
perpetuity.

Wet Pond Maintenance Requirements
Important operation and 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 pond should be fertilized after the initial fertilization that is required to establish
-
the plants on the vegetated shelf.
_ Stable groundcover will be maintained in the drainage area to reduce the sediment load to the wet
pond.
_ If the pond must be drained for an emergency or to perform maintenance, the flushing of sediment
through the emergency drain will be minimized as much as possible.
_ At least once annually, a dam safety expert will inspect the embankment. Any problems that are
found will be repaired immediately.
_ 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.
After the wet pond is established, it will be inspected quarterly 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 shall be kept in a
known set location and shall be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately.

Level Spreader-Filter Strip Maintenance Requirements
important operation and maintenance procedures:
Immediately after the filter strip is established, any newly planted vegetation will be watered twice_
weekly if needed until the plants become established (commonly six weeks).
_ Stable groundcover will be maintained in the drainage area to reduce the sediment load to the level
spreader-filter strip.
Every two weeks during the growing season, the filter strip will be mowed. Turf grass should not be cut
- shorter than 4-6 inches and may be allowed to grow as tali as 12 inches depending on aesthetic
requirements (NIPC, 1993).
_ Once a year, the soil will be aerated if necessary and the filter strip will be reseeded to maintain a dense
growth of vegetation.
- Once a year, soil pH will be tested and lime will be added if necessary.
For the fist two years after the LS-FS is established, it shall be inspected quarterly and within 24 hours after every
storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County). After two years of successful performance,
it will be inspected quarterly. Records of operation and maintenance shall be kept in a known set location and shall be
available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately.
