Subject: State Stormwater Management Permit No. SW8 170316
Finley Farms Subdivision
Low Density Subdivision Project with Curb Outlet Swales
Brunswick County
Dear Mr. Stocks:
The Wilmington Regional Office received a complete, modified State Stormwater Management Permit
Application for the subject project on December 10, 2018 with additional information received on February 20,
2019 and March 7, 2019. 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 effective
January 1, 2017. We are forwarding modified Permit No. SW8 170316, dated March 8, 2019, for the
construction, operation and maintenance of the stormwater control measures (SCMs), built -upon areas, as well
as the stormwater collection system and/or vegetated conveyance system associated with the subject project.
Please replace the previously approved plan sheets with the attached modified and approved versions. In
addition, please replace the previous application (SWU-101), proposed deed restrictions, Low Density
Supplement, and the Operation and Maintenance Agreement with the attached modified versions.
This permit shall be effective from the date of issuance until rescinded and shall be subject to the conditions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 permit conditions regarding the limitation of built -upon area, modification
of the project, the operation and maintenance of the vegetated conveyance system, and the procedures for
changing ownership of and/or transferring the permit. Please also pay attention to the permit conditions that
requires the recordation of deed restrictions and protective covenants, easements, and the maintenance
agreement, which must all be provided along with certification upon completion of the project. Failure to
comply with these requirements will result in future compliance problems.
The following modifications are included and covered by this permit:
The subject property is located in an unincorporated part of Brunswick County, immediately adjacent
to the Tara Forest subdivision, which is within the Town of Leland. A total of 10 proposed lots will
front on Springstone Drive, an existing public roadway. No new roads, sidewalks, or utilities are
proposed on these lots. A new private roadway, Finley Court, will be constructed to provide access to
an additional 8 lots.
The private cul-de-sac will have curb and gutter with a 5:1 curb outlet swale to an amenity pond,
which drains through a conveyance swale to an existing ditch that parallels Springstone Drive. The
lots fronting Springstone Drive will drain directly, and through interconnected amenity ponds, to the
same existing ditch, which drains southeast towards Lanvale Road. The runoff will enter a 3:1 swale /
ditch (Swale No. 3 in Hearthstone) that runs along the back (western) side of many lots, then turns and
runs along the back (southern) side of many lots in Hearthstone, and will outlet at southeastern corner
of the subdivision, where it enters the DOT right-of-way and flows through a pipe under Old Lanvale
Road and into another roadside ditch.
Portions of the ditch along Springstone Drive, in northern part of the Finley Farms development, will
be filled. The Springstone drive right-of-way does not drain directly to the ditch in this area.
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 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.

DIVISION OF ENERGY, MINERAL AND LAND RESOURCES
STATE STORMWATER MANAGEMENT PERMIT
LOW DENSITY SUBDIVISION DEVELOPMENT
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
Finley Properties, LLC
Finley Farms Subdivision
Springstone Drive, Brunswick County
FOR THE
construction, operation and maintenance of a 24% low density subdivision project 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, 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.
The permit shall be effective from the date of issuance until rescinded and shall be subject to the
following specific conditions and limitations:
I. DESIGN STANDARDS
1. This permit is effective only with respect to the management of stormwater described in the
approved plans and specifications. The overall percent of built -upon area (BUA) permitted for
the project must not exceed 24% per the requirements of the stormwater rules. This permit
covers the construction of a total of 97,849 square feet of BUA, which includes 82,007 square
feet of proposed BUA, and 15,842 square feet of future BUA allocation.
2. Each of the eighteen (18) lots are limited to a maximum of 4,000 square feet of built -upon area,
as indicated in the approved plans and specifications.
3. 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. All stormwater runoff, including roof drains, shall be released as dispersed
flow no closer than at the edge of the vegetated setback. At no time shall stormwater runoff be
piped into or through the setback.
4. This project 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.

Permit No. SW8 170316 MOD
5. No piping shall be allowed except those minimum amounts necessary to direct stormwater
runoff beneath a built -upon area such as a road or driveway when it cannot be avoided.
6. The peak flow from the 10-year storm event shall not cause erosion downslope of the
stormwater outlet discharge point.
II. SCHEDULE OF COMPLIANCE
The project shall be constructed in accordance with the conditions of this permit and the
approved plans and specifications.
2. Vegetated areas and vegetated conveyances shall be entirely constructed, vegetated, and
operational prior to the construction of any individual lot development, per the approved plans
and specifications.
3. During construction, erosion shall be kept to a minimum and any eroded areas of the vegetated
areas or vegetated conveyance system will be repaired immediately.
4. All vegetated conveyance systems, stormwater collection systems, and/or maintenance
accesses must be located in public rights -of -way, dedicated common areas that extend to the
nearest public right-of-way, and/or permanent recorded easements that extend to the nearest
public right-of-way for the purpose of inspection, operation, maintenance, and repair.
5. The permittee shall at all times provide and perform the maintenance necessary, as listed in the
signed Operation and Maintenance Agreement titled Swale System Maintenance Requirements,
a part of the Low Density Supplement, to assure that the permitted vegetated conveyance
system functions at the approved design condition. The approved Operation and Maintenance
Agreement is incorporated by reference into this permit and must be followed in its entirety and
maintenance must occur at the scheduled intervals.
6. The operation and maintenance agreement must be recorded with the Office of the Register of
Deeds
7. The final plats for the project must be recorded with the Office of the Register of Deeds prior to
the sale of lots. The recorded plat 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.
8. Recorded deed restrictions and protective covenants must be recorded with the Office of the
Register of Deeds, will be incorporated into this permit by reference, and include, at a minimum,
the following statements related to stormwater management:
a. The following covenants are intended to ensure ongoing compliance with State Stormwater
Management Permit Number SW8 170316, as issued by the Division of Energy, Mineral
and Land Resources under NCAC 2H.1000.
b. The State of North Carolina is made a beneficiary of these covenants to the extent
necessary to maintain compliance with the Stormwater Management Permit.

express written consent of the Division.
e. Alteration of the drainage as shown on the approved plans may not take place without the
concurrence of the Division.
f. The maximum built -upon area per lot is 4,000 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, but is not limited to, structures, asphalt, concrete, gravel, brick, stone, slate,
coquina, driveways, and parking areas, but does not include raised, open wood decking, or
the water surface of swimming pools.
g. Built -upon area in excess of the permitted amount will require a permit modification to
ensure compliance with the permit and stormwater rules.

vegetated setback. At no time shall stormwater runoff be piped into or through the setback.
k. Any individual or entity found to be in noncompliance with the provisions of a stormwater
management permit or the requirements of the stormwater rules is subject to enforcement
procedures as set forth in NCGS 143, Article 21.
9. For each lot, 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.
10. The maximum built -upon area assigned to each lot via this permit and the recorded deed
restrictions and protective covenants may not be increased or decreased by either the
individual lot owner or the permittee unless and until the permittee notifies the Division
and obtains written approval from the Division.
11. The permittee shall review each lot for new construction and all subsequent modifications and
additions to ensure compliance with the conditions of the permit and the approved plans and
specifications. The plans reviewed must include all proposed built -upon area, grading, and
driveway pipe placement. The permittee shall not approve any lot plans where the maximum
allowed built -upon area has been exceeded, or where modifications to the grading or to the
storm drainage system are proposed unless and until a permit modification has been approved
by the Division. The permittee may establish an Architectural Review Board (ARB) or
Committee (ARC) to conduct these reviews. However, any approval given by the ARB or ARC
on behalf of the permittee does not relieve the permittee of the responsibility to maintain
compliance with the conditions of the permit and the approved plans and specifications.
12. The permittee is responsible for verifying that the proposed built -upon area on each individual lot
and for the entire project does not exceed the maximum amount allowed by this permit. The
