This permit shall be effective from the date of issuance until July 11, 2017 and shall be subject to the following specified conditions and limitations: I. DESIGN STANDARDS 1. This permit is effective only with respect to the nature and volume of stormwater described in the application and other supporting data. 2. The overall tract built-upon area percentage for the project must be maintained at 30% per the requirements of Section .1005 of the stormwater rules. This project is permitted for a maximum of 75,723 square feet of BUA. 3.

The subdivision is permitted for 13 lots, each allowed a maximum of 4,250 square feet of built-upon area. 5. The low density portions of this project will maintain a minimum 30 foot wide vegetated buffer between all impervious areas and surface waters. Page 2 of 8 State Stormwater Management Systems Permit No. SW8 070232 MOD 6. Within the low density portions of the permitted project, the only runoff conveyance systems allowed will be vegetated conveyances such as swales with minimum side slopes of 3:1 (H:V) as defined in the stormwater rules and as shown on the approved plan. 7. The following design elements have been permitted for this wet detention pond stormwater facility, and must be provided in the system at all times. a.

No homeowner/lot owner/developer shall fill in, alter, or pipe any drainage feature (such as swales) shown on the approved plans as part of the stormwater management system without submitting a revision to the permit and receiving approval from the Division. 2. The permittee is responsible for verifying that the proposed built-upon area for the entire lot does not exceed the maximum allowed by this permit. Once the lot transfer is complete, the built-upon area may not be revised without approval from the Division of Water Quality, and responsibility for meeting the built-upon area limit is transferred to the individual property owner. 3. If an Architectural Review Board or Committee is required to review plans for compliance with the BUA limit, the plans reviewed must include all proposed built-upon area. Any approvals given by the Board do not relieve the homeowner of the responsibility to maintain compliance with the permitted BUA limit. 4. The Director may notify the permittee when the permitted site does not meet one or more of the minimum requirements of the permit. Within the time frame specified in the notice, the permittee shall submit a written time schedule to the Director for modifying the site to meet minimum requirements.

The stormwater management system shall be constructed in its entirety, vegetated and operational for its intended use prior to the construction of any built-upon surface. 6. The runoff from all built-upon area within the drainage area of the pocket of high density permitted stormwater system must be directed into the permitted stormwater control system. 7. Within the low density portions of the permitted project, all roof drains shall terminate at least 30 feet from the mean high water mark of surface waters. 8. The permittee shall submit to the Director and shall have received approval for revised plans, specifications, and calculations prior to construction, for any modification to the approved plans, including, but not limited to, those listed below: a. Any revision to the approved plans, regardless of size. b. Project name change. C. Transfer of ownership. d. Redesign or addition to the approved amount of built-upon area. e. Further subdivision, acquisition, or sale of all or part of the project area. The project area is defined as all property owned by the permittee, for which Sedimentation and Erosion Control Plan approval or a CAMA Major permit was sought. f. Filling in, altering, or piping of any vegetative conveyance shown on the approved plan. 9. The Director may determine that other revisions to the project should require a modification to the permit. 10. All stormwater collection and treatment systems must be located in either dedicated common areas or recorded easements. The final plats for the project must be recorded showing all such required easements, in accordance with the approved plans. 11. During construction, erosion shall be kept to a minimum and any eroded areas of the system will be repaired immediately. 12. Upon completion of construction, prior to issuance of a Certificate of Occupancy, and prior to operation of this permitted facility, a certification must be received from an appropriate designer for the system installed certifying that the permitted facility has been installed in accordance with this permit, the approved plans and specifications, and other supporting documentation. Any deviations from the approved plans and specifications must be noted on the Certification. 13. If the stormwater system was 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. 14. Unless otherwise shown, permanent seeding requirements for the stormwater control must follow the guidelines established in the North Carolina Erosion and Sediment Control Planning and Design Manual. 15. This permit shall become void unless the facilities are constructed in accordance with the conditions of this permit, the approved plans and specifications, and other supporting data.

NCDOT has replaced all the existing storm-water drainage pipes along Goodland Road, in doing so the have raised the elevation of the pipe that our site drains to. This has caused us to change the elevations of our storm water pond, (normal pool, temporary pool, orifice and outlet structure elevations). These minor changes were caused by circumstances outside of our control, therefore all modifications were done using the requirements that were in place at the time of the previous submittal. If you have any questions concerning this matter please contact me at (910) 383.1044 ext. 119 or email me at mike.tackett@capefearengineering.com. Sincerely, Michael Tackett, P.L.S.

The project area to be disturbed is approximately 1.45 acres. Drainage considerations are to be in accordance with DWQ storm water requirements. This submittal is for revisions to the approved Storm Water Permit SW8 070232. Existing Site: Site topography in the area is relatively flat for the most part with some slopes typically less than three (3) percent. Vegetation consists primarily of grasses and minor ground cover. Subsurface soils are typically a mixture of sands, silty sands and organics. Proposed Improvements: Improvements proposed include drainage devices, streets, and utilities. Drainage for the most part will sheet flow from the lots into the streets which will have curb and gutter to direct drainage to low points in the roads. Drainage from the low points will drain into a stormwater pond. The pond will drain to surrounding wetlands.
