VEGETATED CONVEYANCES. 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. e. CURB OUTLET SYSTEMS. Each designated curb outlet must convey stormwater runoff to a vegetated conveyance or vegetated area as shown on the approved plans and specifications. The conveyance must be maintained with a dense vegetated cover at a minimum of 100' long, side slopes at 3:1 (H:V) or flatter, a minimum bottom width of 2 feet, and a longitudinal slope no steeper than 5% to carry the peak flow from the 10-year storm at a non -erosive velocity. 4. STORMWATER OUTLETS. The peak flow from the 10-year storm event shall not cause erosion downslope of the discharge point. 5. VEGETATED SETBACKS. A 30-foot wide vegetative setback must be provided and maintained in grass or other vegetation adjacent to all surface waters as shown on the approved plans. The setback is 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. a. BUA IN THE VEGETATED SETBACK. BUA may not be added to the vegetated setback except as shown on the approved plans or in the following instances where the BUA has been minimized and channelizing runoff from the BUA is avoided: i. Water dependent structures; and ii. Minimal footprint uses such as poles, signs, utility appurtenances, and security lights that cannot practically be located elsewhere. b.

Consultant's Certification (MDC 15A NCAC 02H .1003) Project Density and Built -Upon Area OAs-built ON/E ON/A 1. The project has areas of high density based on natural drainage area boundaries, variations in land use or construction phasing. Y or N 2. The project's built -upon area does not exceed the maximum limit specified in the permit. Y or N Dispersed Flow OAs-built ON/E ON/A 1. The project maximizes dispersed flow through vegetated areas and minimizes channelized flow. Y or N Page 5of7 Post -Construction Stormwater Management Permit No. SW6210906 Vegetated Conveyances OAs-built ON/E ON/A 1. Stormwater that is not released as dispersed flow is transported Y N by vegetated conveyances. or 2. The project has a minimal amount of non -vegetated conveyances Y N to reduce erosion. or 3. Other than minimal piping under driveways and roads, no piping Y N has been added beyond what is shown on the approved plans. or 4. Side slopes are no steeper than 3H:1 V. Y or N 5. The conveyance does not erode in response to the peak flow from Y N the 10-year storm. or Curb outlet systems (if applicable) OAs-built ON/E ON/A 1. The swale or vegetated area can carry the peak flow from the Y N 10-year storm at a non -erosive velocity. or 2. The longitudinal slope of the swale or vegetated areas does not Y N exceed 5%. or 3. The swale has a trapezoidal cross-section and a minimum bottom Y N width of two feet. or 4. The minimum length of the swale or vegetated area is 100 feet. Y or N 5. Side slopes are no steeper than 3H:1 V. Y or N 6. The project utilizes treatment swales designed per Section .1061 Y N in lieu of the curb outlet system requirements. or Vegetated Setbacks (if applicable) OAs-built ON/E ON/A 1. The width of the vegetated setback is at least 50'. Y or N 2. The width of the vegetated setback has been measured from the normal pool of impounded waters, the MHW line of tidal waters, Y or N or the top of bank of each side of rivers or streams. 3. The vegetated setback is maintained in grass or other vegetation. Y or N 4. BUA that meets the requirements of NCGS 143-214.7(b2)(2) is Y N located in the setback. or 5. BUA that does NOT meet the requirements of NCGS 143- 214.7(b2)(2) is located within the setback and is limited to: • Publicly -funded linear projects (road, greenway, or sidewalk) Y N • Water dependent structures or • Minimal footprint uses such as poles, signs, utility appurtenances, and security lights. 6. The amount of BUA within the setback is minimized, and Y N channeling of the runoff from the BUA has been avoided. or 7. Stormwater is not discharged (via swale or pipe) through a vegetated setback. Stormwater is released at the edge of the Y or N setback and allowed to flow through the setback as dispersed flow. Page 6of7 Post -Construction Stormwater Management Permit No. SW6210906 Outlets OAs-built ON/E ON/A 1. Stormwater outlets do not cause erosion downslope of the discharge point during the peak flow from the 10-year storm. Y or N Variations OAs-built ON/E ON/A 1. The project has variations from the MDC that were not previously approved. (Modification may be required.) Y or N Deed restrictions (if applicable) OAs-built ON/E ON/A 1.
