For those lots within CAMA's Area of Environmental Concern, where DCM calculates a different maximum lot built -upon area, the governing lot BUA shall be the more restrictive of the two numbers. h. All runoff from the built -upon areas on the lot must drain into the permitted system. This may be accomplished through providing roof drain gutters, which drain to the pond or to the street, grading the lot to drain toward the pond or street, or grading perimeter swales and directing them into the pond or street. i. Built -upon area in excess of the permitted amount will require a permit modification. j. All affected lots shall maintain a 50' wide vegetative buffer adjacent to all surface waters, measured horizontally from and perpendicular to the normal pool of impounded structures, the top of bank of both sides of streams and rivers and the mean high water line of tidal waters. Page 5 of 9 State Stormwater Management Systems Permit No. SW8 121103 k.

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: — 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). — Once a year, the filter strip will be reseeded to maintain a dense growth of vegetation — Stable groundcover will be maintained in the drainage area to reduce the sediment load to the vegetation. — Two to three times a year, grass filter strips will be mowed and the clippings harvested to promote the growth of thick vegetation with optimum pollutant removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and may be allowed to grow as tall as 12 inches depending on aesthetic requirements (NW,1993). Forested filter strips do not require this type of maintenance. — Once a year, the soil will be aerated if necessary. — Once a year, soil pH will be tested and lime will be added if necessary. After the filter strip is established, it will be inspected quarterly and within 24 hours after every storm event greater than 1.0 inch (or 1.5 inches if in a Coastal County).

PROJECT INFORMATION 1. In the space provided below, briefly summarize how the stormwater runoff will be treated. All runoff will be collected from lots via gutters and grading and directed to the road where it will sheet flow to the wet detention basin inlet flume. The wet basin is designed for 90% TSS removal. The outfall of the basin is direccted to a LSVF which serves as a secondary BMP. 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.lf 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 River basin. 4. Total Property Area: 3.11 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+:3.11 acres Total project area shall be calculated to exclude the following the normal yool of impounded structures, the area between the banks of streams and rivers, the area below the Normal High Water (NHW) line or Mean High Water (MHW) line, and coastal wetlands landward from the NHW (or MHM line. The resultant project area is used to calculate overall percent built upon area (BUA). Non -coastal wetlands landward of the NHW (or MHW) line may be included in the total project area. 8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 = 23.3 (50.0 of uplands) % 9. How many drainage areas does the project have?l (For high density, count 1 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 provided in the same format as below.

ECEI M JUN 1 1 2013 I BY, 9e 3 of 3 �1 $ r „ 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, Thomas Nelson , 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 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 _2,043 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. 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.
