Annual Avg Daily Traffic (veh/hr/day): Desi n/Future: 520 Year: 2025 Existin : 260 Year: 2009 General Project Narrative: The North Carolina Department of Transportation (NCDOT) has proposed to replace Guilford County Bridge #240 on Causey Lake Road (SR 3285) over Little Alamance Creek. (Description of Minimization of Water The existing structure is a three span bridge (1 @25'-3", 1@25'0", 1@25'3") PPCC with PPC caps on timber piles for both interior and end bents. The proposed structure is a Quality Impacts) single span (1 @90'), 33" PCBB with 4' deep caps. This structure has been designed to have as little environmental, wetland, and surFace water impacts as possible. 2:1 roadway fill slope will be used in the wetland areas to minimize wetland impacts. Permanent drainage easement (PDE) will be set to have as little wetland impacts as possible. To avoid direct discharge of bridge storm water into the receiving water, deck drains are not required for the proposed bridge. Storm water impacts to the stream have been minimized by utilizing grated inlets and pipes to collect bridge storm water and use rip rap outlet protection at 16+25 RT to dissipate energy to provide a diffuse flow (non-erosive sheet flow) in a wooded area. This diffuse flow will run for a distance of 12'+/- before entering the buffer. At the southwest quadrant an existing roadside ditch will transition at 14+00 LT into a 2' based ditch. The ditch will outlet onto rip rap at embankment to dissipate energy to provide a non-erosive outlet velocity to the stream. At the southeast quadrant an existing roadside ditch will transition at 13+50 RT into a 2' base ditch with Class B rip rap. The ditch will outlet onto rip rap at embankment to dissipate energy to provide a non-erosive outlet velocity to the stream. At the northeast quadrant an existing roadside ditch will transition at 18+33 RT into a V ditch then at 18+00 RT transition into a 2' based ditch with Class B rip rap. The ditch outlets at the wetland boundary with a non-erosive velocity. At the northwest quadrant an existing roadside ditch will outfall into a 18" pipe that will convey flow and outlet at 17+00 LT and use rip rap outlet protection to dissipate energy to provide diffuse flow (non-erosive sheet flow). The sheet flow will flow 10'+/- before entering the wetland. Due to the nature of low impact bridge replacement, the increases in stormwater discharges (post vs pre condition) are insignificant and the existing ditches do not need to be modified. Therefore, additional stormwater measures are not required.
