Dee Freeman
Secretary
The Stormwater Permitting Unit received a complete Stormwater Management Permit Application for The
Summit, Section Four on September 11, 2012. 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 21-1.1000 and
Session Law 2006-246, We are forwarding Permit No. SW6120804, dated September 21, 2012, 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 September 21, 2020 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.
f any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to
request an adjudicatory hearing upon written request within thirty (30) days following receipt of this permit.
This request must be in the form of a written petition, conforming to Chapter ISO of the North Carolina

IV. PROJECT INFORMATION
1. In the space provided below, briefly summarize how the stormwater runoff will be treated.
Stormwater runoff will dischab,,7e into infiltration basins where the runoff will infiltrate into theexistin
sandy, deep soil which is typical -for this site. The basins are sized to handle 2.5 times the treatment
volume at 1 2 the soil infiltration rate.
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 Cape Fear. �T River basin.
4. Total Property Area: 17.86 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*:17.86 acres
Total project area shall be calculated to exclude the following: the normal pool of im ounded structures, the area
between the banks of streams and rivers, the area below the Normal Higgh Water (NM line or Mean High Water
(MHW) line, and coastal wetlands landward from the NHW (or MHi line. The resultant project area is used to
calculate overall percent built upon area (BLIA). Non -coastal wetlands landward of the NHW (or MH1M line may
be included in the total project area.
8. Project percent of impervious area: (Total impervious Area / Total Project Area) X 100 =31.1 %
9. How many drainage areas does the project have?2 (For high density, count I for each proposed engineered
stormwater BMP. For low density and other projects, use 1 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

High DensBy 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, E. Frank Weaver, Ill , 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 Sk/6 t Zo ?o , as issued by the Division of Water Quality 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 Water Quality.
5. Alteration of the drainage as shown on the approved plan may not take place without the concurrence
of the Division of Water Quality.
6. The maximum allowable built -upon area per lot is 6,000 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 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 Lot # BUA Lot # BUA
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.
i. 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.

Infiltration 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.
Important maintenance procedures:
The drainage area will be carefully managed to reduce the sediment load to the
infiltration basin.
- Immediately after the infiltration basin is established, the vegetation will be
watered twice weekly if needed until the plants become established (commonly
six weeks).
- No portion of the infiltration basin will be fertilized after the initial fertilization
that is required to establish the vegetation.
- The vegetation in and around the basin will be maintained at a height of
approximately six itches.
After the infiltration basin is established, it will be inspected once a quarter 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.
