Salisbury Street Raleigh, North Carolina 27604 March 14, 2019 SUBJECT: Request for Buffer Authorization NC 55 (Neuse Blvd.) at SR 1395 (Dr. M. L. King, Jr. Blvd.) Roundabout NCDOT STIP U-5993 Craven County, North Carolina STV Engineers, Inc., Project No. 4018807 Hello Ms. Chapman, On behalf of the North Carolina Department of Transportation (NCDOT) Division 2, STV Engineers, Inc., (SN) is requesting a Neuse Riparian Buffer Authorization from the North Carolina Department of Environmental Quality (NCDEQ) - Division of Water Resources (DWR). The NCDOT Division 2 is proposing intersection improvements that would convert the current signalized intersection of NC 55 and SR 1395 to a roundabout which would improve traffic flow and safety. The project study area (PSA), located in New Bern, N.C., encompasses approximately 22.4 acres and consists primarily of NC 55 (Neuse Blvd.) and SR 1395 (Dr. M. L. King, Jr. Blvd.) as well as some developed residential and commercial properties. The site is located in the Lower Neuse (HUC8 03020204) drainage basin. There is one stream located within the PSA which is an unnamed tributary (U.T.) to Jack Smith Creek. The U.T. to Jack Smith Creek was determined to be a relatively permanent water (RP1l� with perennial flow. The stream (RPW) is depicted on the USGS mapping and is subject to North Carolina's Neuse River riparian buffer rules. Enclosed please find the following: Riparian Buffer Authorization Form (Attachment A); USGS and NRCS Soil Survey excerpts (Attachment B); Permit Drawings, Stormwater Management Plan, and Riparian Buffer Impacts Summary Sheet (Attachment C). We are hereby requesting a riparian buffer authorization for impacts associated with the project. Please contact the below signed at (704) 816-2519 or NCDOT's Project Manager, Elizabeth Workman-Maurer, at (919) 854-6221 should you have any questions or concerns regarding this request.

Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: Land use in the project vicinity consists primarily of maintained/disturbed areas that includes the roadway right-of-way, as well as residential and commercial development. An unnamed tributary to Jack Smith Creek flows northeast through the PSA and is piped under the roadway east of the existing intersection. Portions of the PSA have an overstory of mixed pine-hardwood vegetation that are located along the stream corridor that bisects the project study area. Much of the existing stormwater infrastructure is undersized and in need of increased ca acit to reduce overflowin durin lar e storm events. 3b. Attach an 8'h x 11 excerpt from the most recent version of the USGS topographic map indicating the location of the site 3c. Attach an 8'h x 11 excerpt from the most recent version of the published County NRCS Soil Survey Map de ictin the ro'ect site 3d. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: 641 3e. Explain the purpose of the proposed project: The ur ose of this ro'ect is to im rove safet and o timize traffic o erations at this intersection. 3f. Describe the overall project in detail, including the type of equipment to be used: The NCDOT Division 2 is planning intersection improvements that would convert the current signalized intersection of NC 55 and SR 1395 to a roundabout which would improve traffic flow and safety. At the time of roadway construction, the stormwater drainage within the project limits will be upgraded to improve the system to the maximum extent practicable given current conditions and constraints. Many of the existing pipes within the project limits are undersized. BMP's utilized to dissipate energy, provide diffuse flow and reduce pollutants reaching the U.T. to Jack Smith Creek include a grassed swale, preformed scour hole with vegetated permanent soil reinforcement mat (PSRM), and riprap energy dissipaters at existing outFalls. A temporary detour will be utilized for eastbound traffic just south of the existing intersection while the proposed roadway is under construction. The project would be completed utilizing heavy equipment including but not limited to skid steer loaders, dump trucks, bulldozers, excavators, and other common roadway construction equipment. No impacts are anticipated to U.T. to Jack Smith Creek during project construction. There will not be an increase in im ervious surface due to the ro'ect. 4. Jurisdictional Determinations 4a.

Comments: D. Impact Justification and Mitigation 1. Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. The preformed scour hole (Appendix C— Sheets 2& 3) was moved as far back from the stream as possible without having to impact the adjacent business. Stormwater pipes were designed to discharge farther up along a grassed swale (Appendix C— Sheet 2) to improve nutrient reduction and the grassed swale was widened to reduce velocit . There are not an antici ated im acts to U.T. to Jack Smith Creek. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Silt fencing will be placed to protect water quality from sediment created through project activities. Existing asphalt will be removed in several locations for a total of 336 ft2 of Zone One Riparian Buffer and 561 ft2 of Zone Two Riparian Buffer. These areas will be allowed to revegetate and will help in decreasin im ervious surface and reducin nutrients reachin the stream. FORM: BA 10-2013 Page 3 of 5 2. Buffer Mitigation 2a. Will the project result in an impact within a protected riparian buffer that Yes No requires buffer mitigation? 2b.

If no, then discuss what type of mitigation is proposed. 2f. Comments: E. Diffuse Flow Plan All buffer impacts and high ground impacts require diffuse flow or other form of stormwater treatment. Include a plan that fully documents how diffuse flow will be maintained. If a Level Spreader is proposed, attach a Level Spreader Supplement Form. If due to site constraints, a BMP other than a level spreader is proposed, please provide a plan for stormwater treatment as outlined in Chapter 8 of the NC Stormwater BMP Manual and attach a BMP Supplement Form. � Diffuse flow ❑ Other BMP F.

There is one existing culvert that appears to be in good condition, therefore there are no major drainage structures involved with the construction of the Quality Impacts) roundabout. A grassed swale, a preformed scour hole with vegetated permanent soil reinforcement mat (PSRM), and riprap energy dissipaters are used for treatment when BMP design standards could be met. The grassed swale is used to reduce flow velocity, promote sedimentation, infiltration, and runoff attenuation. The preformed scour hole reduces outlet velocity from a pipe outfall and reduces the risk of stream bank erosion. Riprap energy dissipater pads reduce outlet velocities at pipe outfalls and reduce the risk of erosion along the streambanks. Riprap will be placed along the streambanks above the normal water surface elevation.
