PROJECT INFORMATION Project No: BD-5109AE County: Stokes WBS No: 45355.1.31 Document: PCE Data Sheet Attachment G F.A. No: BRZ-1998(2) Funding: State Federal Federal Permit Required? Yes No Permit Type: NWP 3 Project Description: As part of the Low Impact Bridge Program, NCDOT’s Division 9 proposes to replace Bridge No. 45 on SR 1998 (Mountain View Church Road) over Brushy Fork Creek in Stokes County. Bridge No. 45 was built in 1966, and is considered to be structurally deficient and functionally obsolete. There may be minor ditch-line impacts, and an off-site detour is to be used during construction. The Area of Potential Effects (APE) will measure approximately 60 feet to either side of the centerline of the roadway/bridge and 300 feet from either end of the bridge. Based on these measurements and the size of the existing bridge, the APE measures approximately 75,787 square feet or about 1.74 acres, inclusive of the existing roadway and the existing structure to be replaced. SUMMARY OF CULTURAL RESOURCES REVIEW Brief description of review activities, results of review, and conclusions: A map review and site file search was conducted at the Office of State Archaeology (OSA) on Tuesday, March 31, 2015. An archaeological survey at this particular bridge location has never been conducted, and no archaeological sites have been recorded within one-half (1/2) mile of the proposed project. Digital copies of HPO’s maps (King Quadrangle) as well as the HPOWEB GIS Service (http://gis.ncdcr.gov/hpoweb/) were last reviewed on Monday, April 6, 2015. There are no known historic architectural resources within the vicinity of the project area that may have intact archaeological deposits within the footprint of the proposed project. In addition, topographic maps, historic maps (NCMaps website), USDA soil survey maps, and aerial photographs were utilized and inspected to gauge environmental factors that may have contributed to historic or prehistoric settlement within the project limits, and to assess the level of modern, slope, agricultural, hydrological, and other erosive-type disturbances within and surrounding the archaeological APE. Brief Explanation of why the available information provides a reliable basis for reasonably predicting that there are no unidentified historic properties in the APE: This is a Federally funded project that will require a Federal permit; no permanent and/or temporary easements will be required. All proposed project activities are to take place within the proposed APE, defined as 60 feet to either side of centerline and 300 feet from either end of the bridge. Since NCDOT’s existing ROW along SR 1988 (Mountain View Church Road) measures 60 feet wide, there may be environmental impacts beyond what is currently owned/maintained by the NCDOT. A 100-foot ROW is being proposed. From an environmental perspective, the APE falls within the Piedmont physiographic region, consists of the floodplain for Brushy Fork Creek and steeply rolling terrain characteristic of the North Carolina Foothills, and is composed of two (2) soil types: Fairview-Poplar Forest complex, 2-8% Project Tracking No.: “No ARCHAEOLOGY SURVEY REQUIRED” form for Minor Transportation Projects as Qualified in the 2007 Programmatic Agreement. 2 of 3 15-03-0040 slopes, moderately eroded (FpB2), and Rhodkiss, Fairview, and Stott Knob soils, 25-60% slopes (RpE). Over the past 20 years, soil unit names within Stokes County have changed, but their characteristics have remained the same. However, what was labelled in 1995 as Riverview- and Toccoa soils, 0-4% slopes, occasionally flooded (RtA) has since been changed to Fairview-Poplar Forest complex, 2-8% slopes, moderately eroded (FpB2), having succumbed to erosion over the past 2 decades. The Office of State Archaeology (OSA) has not reviewed any projects in the vicinity for their potential to impact archaeological resources. Given the degree of erosion, occasional flood activity, and the steeply sloping topography within the APE, it is believed that the project area, as depicted, is unlikely to contain intact and significant archaeological resources. Based on the information above, there should be no archaeological survey required for this project. If design plans change or are made available prior to construction, then additional consultation regarding archaeology will be required. At this time, no further archaeological work is recommended. If archaeological materials are uncovered during project activities, then such resources will be dealt with according to the procedures set forth for “unanticipated discoveries,” to include notification of NCDOT’s Archaeology Group.

The SMP summarizes project information and post-construction source control and treatment measures selected to mitigate impacts. This information is used to support federal and state environmental permit applications during the design stage of a project. For Merger projects, SMPs with permit drawings are required at the 4C Concurrence Point Meeting. Refer to Section 2.5 of the North Carolina Department of Transportation (NCDOT) Stormwater Best Management Practices Toolbox (2008) for further information regarding the Stormwater Management Plan. An SMP is required for all projects designed by or for the Hydraulics Unit. Division led projects may have different SMP threshold requirements.

General Project Narrative:This project is a low impact bridge replacement project and is located to the north and east of King. The area is rural in nature and the surrounding terrain is rolling hills. The existing bridge on Mountain View Church Road over Brushy Fork Creek was built in 1966 and is 61' long and 25.5' wide. The bridge is both structurally deficient and functionally obsolete and has a sufficiency rating of 21.54 out of 100. It is constructed of timber components and precast, prestressed concrete channels. The proposed bridge will be 90' long and 30' wide. It will be a precast prestressed concrete box beam bridge on a concrete substructure. It will fully span the creek and will not create any impacts to the natural flow of Brushy Fork Creek. The approach roadway on each end of the bridge will be updated to current design standards and guardrail will be placed on each corner of the new bridge where currently there isn't any guardrail. The existing roadway will be widened only slightly to tie into the new bridge width. The paved roadway width will match the existing width of 20'. There will be no deck drains placed over the stream on this bridge; they will be over the floodplain area. The remaining surface water will drain off the bridge to the north end where the water will be captured in one concrete drainage structure. The water will then flow out through a 15" drainage pipe. There will be a rip rap energy dissipator at the outlet of the pipe. The outlet of the pipe will be approximately 45' from the edge of the stream. The outlet area is flat and well vegetated. All water from the roadway will flow through vegetation prior to entering the stream; there will be no direct discharge into the stream. There will be approximately 100 linear feet of total impacts to Brushy Fork Creek. This is due to bank stabilization and bank reconstruction. There are existing bridge elements that are currently impacting the stream, when these are removed we will be stabilizing the banks with rip rap. Also, the existing interior bent has caused the stream to divert around it over time and has caused the stream to overwiden and become shallow. To prevent the stream from widening any further and to return it to its normal width we are proposing to reconstruct the northern streambank with rip rap. The 100' includes the new impacts of 50' due to the stabilization and bank reconstruction, 35' of existing impacts that will now be stabilized with rip rap and 15' of temporary impacts for installation of an impervious dike. All impacts are being proposed to prevent the stream from overwidening and to return the channel to its normal flow. A single span box beam has been utilized at this location to avoid impacts to the stream. Typical Cross Section Description: References 870 (2013) 0.16 Average Daily Traffic (veh/hr/day): ac.
