Pender County
Dear Mr. Sosne:
The Wilmington Regional Office issued the subject permit on November 22,2021 and recently discovered it
contained an error. This permit correction is necessary to incorporate the requirements of Section 4(a)of Session
Law 2021-158,which became effective on September 16,2021 and is now included in G.S. 1.43-214.7(b4).
Please replace the previously issued permit with the enclosed correct permit. This corrected permit does not
impose new or different design standards;it merely restates some of the previous terms to provide you with a
better understanding of your obligations under the permit.
This project is subject to the conditions and limitations as specified in the corrected permit. Please pay special
attention to the conditions listed in this permit regarding the Operation and Maintenance of the BMP(s),
recordation of deed restrictions,certification of the project,procedures for cringes 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 transfer 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,and must be filed with the

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.
4. 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 or in the following instances where the BUA has
been minimized and channelizing runoff from the BUA is avoided:
i. Water dependent structures; and
ii. Minimal footprint uses such as poles, signs, utility appurtenances, and security
lights that cannot practically be located elsewhere.
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 prior to the sale of individual
lots or groups of lots:
a. ACCESS AND/OR EASEMENTS. The entire stormwater conveyance system, including any
SCMs, and maintenance accesses must be located in public rights-at-way, dedicated
common areas that extend to the nearest public right-of-way, and/or permanent recorded

Wet Detention Pond Maintenance Requirements
The wet detention basin system is defined as the wet detention basin,pretreatment including forebays and the vegetated filter if one is
provided.
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.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately.

High Density Residential Subdivisions
Deed Restrictions & Protective Covenances
In accordance with Title 15 NCAC 2H.1000 and S.L. 2006-246,the Stormwater Management Regulations,
deed restrictions and protective covenants are required for High Density Residential Subdivisions where
lots will be subdivided and sold and runoff will be treated in an engineered stormwater control facility. Deed
restrictions and protective covenants are necessary to ensure that the development maintains a"built-upon"
area consistent with the design criteria used to size the stormwater control facility.
I, Adam Sosne , acknowledge, affirm and agree by my signature below, that I will
cause the following deed restrictions and covenants to be recorded prior to the sale of any lot:
1. The following covenants are intended to ensure ongoing compliance with State Stormwater
Management Permit Number SW8 210310 , as issued by the Division of Energy, Mineral and
Land Resources under the Stormwater Management Regulations.
2. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to
maintain compliance with the stormwater management permit.
3. These covenants are to run with the land and be binding on all persons and parties claiming under
them.
4. The covenants pertaining to stormwater may not be altered or rescinded without the express written
consent of the State of North Carolina, Division of Energy, Mineral and Land Resources.
5. Alteration of the drainage as shown on the approved plan may not take place without the concurrence
of the Division of Energy, Mineral and Land Resources.
6. The maximum allowable built-upon area per lot is See Below square feet. This allotted amount
includes any built-upon area constructed within the lot property boundaries, and that portion of the
right-of-way between the front lot line and the edge of the pavement. Built upon area includes, bui is not
limited to, structures, asphalt, concrete, gravel, brick, stone, slate, coquina and parking areas, but does
not include raised, open wood decking, or the water surface of swimming pools.
OR, if the proposed built-upon areas per lot will vary, please REPLACE#6 above with the following:
6. The maximum built-upon area per lot, in square feet, is as listed below:
Lot# BUA Lot# BUA
1-175 (Single Family) 3,000 SF/Lot 176-316(Townhomes) See Attached
This allotted amount includes any built-upon area constructed within the lot property boundaries, and
that portion of the right-of-way between the front lot line and the edge of the pavement. Built upon area
includes, but is not limited to, structures, asphalt, concrete, gravel, brick, stone, slate, coquina and
parking areas, but does not include raised, open wood decking, or the water surface of swimming
pools.
7. Each lot will maintain a 30**foot wide vegetated buffer between all impervious areas and surface
waters.
"50 foot for projects located in the 20 coastal counties.
8. All runoff from the built-upon areas on the lot must drain into the permitted system. This may be
accomplished through a variety of means including roof drain gutters which drain to the street, grading
the lot to drain toward the street, or grading perimeter swales to collect the lot runoff and directing them
into a component of the stormwater collection system. Lots that will naturally drain into the system are
not required to provide these additional measures.
