Sydes Construction, Inc. Fenwick Isle at Bluewater Rise Off of Old Airport Road, Craven County FOR THE construction, operation and maintenance of a 24% low density subdivision project with a curb outlet swale system in compliance with the provisions of Session Law 2008-211 and Title 15A NCAC 2H .1000 (hereafter referred to as the "stormwater rules') and the approved stormwater management plans and specifications, and other supporting data as attached and on file with and approved by the Division of Energy, Mineral and Land Resources (hereafter referred to as the Division or DEMLR) and considered a 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 The Permit shall be effective from the date of issuance until rescinded and shall be subject to the following specific conditions and limitations: I. DESIGN STANDARDS The overall tract built -upon area percentage for the project must be maintained at 24% per the requirements of the stormwater rules. This permit covers the construction of a total of 323,497 square feet of built -upon area (BUA). 2. Each of the 40 lots is limited to a maximum of 4,000 square feet of built -upon area, as indicated on the application and as shown on the approved plans. 3. This project proposes a curb outlet system. Each designated curb outlet swale or 100' vegetated area shown on the approved plan must be maintained at a minimum of 100' long, maintain 5:1 (H:V) side slopes or flatter, have a longitudinal slope no steeper than 5%, carry the flow from a 10 year storm in a non -erosive manner, and maintain a dense vegetated cover. 4. Runoff conveyances other than the curb outlet system swales, such as perimeter ditches, must be vegetated with side slopes no steeper than 3:1 (H:\/). 5. Three wet detention ponds are provided to meet the City of New Bern Stormwater guidelines and are not covered by this permit. No piping shall be allowed except those minimum amounts necessary to direct runoff beneath an impervious surface such as a road or under driveways to provide access. By the issuance of this permit, the Division is granting a minor variance from the no piping requirements as set in 15A NCAC 2H. 1 005(2)(a)(ii), at several locations. The locations covered by this variance are the outlets for proposed BMP's 1. and 2 and the piping between lots 1 and 2, 4 and 5, 25 and 26, 36 and 37, 38 and 39. The proposed BMP's will provide better treatment of the stormwater runoff than the vegetated swales lost by approved piping. Page 1 of 5 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. Filling in, piping or altering any 3:1 vegetated conveyances (ditches, swales, etc.) associated with the development except for average driveway crossings, is prohibited by any persons. h Filling in, piping or altering any designated 5:1 curb outlet swale or vegetated area associated with the development is prohibited by any persons. i. A 50-foot wide buffer must be provided adjacent to 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 waterline of tidal waters. j. All roof drains shall terminate at least 50' from the normal pool of impounded structures, the banks of rivers and streams and the Mean High Waterline of tidal waters. k. Each designated curb outlet swale or 100' vegetated area shown on the approved plan must be maintained at a minimum of 100'iong, maintain 5:1 (H:V) side slopes or flatter, have a longitudinal slope no steeper than 5%, carry the flow from a 10 year storm in a non -erosive manner, maintain a dense vegetated cover, and be located in either a dedicated common area or a recorded drainage easement. I. 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 N.C.G.S. 143, Article 21. 9.

Further subdivision, acquisition or sale of the project area in whole or in part. 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. d. Filling in, piping, or altering any vegetative conveyance shown on the approved plan, except the minimum driveway crossings. e. The development of any future area or additional phase(s) noted on the approved plans. 11. All stormwater conveyances will be located in either public rights -of -way, dedicated common areas or drainage easements.
