Waterbody Information2013NCDWR Stream Index No.:45575.1.1Impairments:Other Stream Classification: Primary Classification: Project Built-Upon Area (ac.)State project B-5620 involves the replacement of Beaufort County Bridge #060030 on NC 33 over Campbell Creek. The existing bridge consists of 1 @ 25' - 6", 1 @ 24' - 11", 1 @ 25' - 1", and 1 @ 25'- 5" reinforced concrete floor and continuous I-beams on reinforced concrete caps and timber piles. It is to be replaced with a 1 @ 45' - 0", 1 @ 50' - 0" and 1 @ 45' - 0", 21" cored slab (140' total length, 33' total width) 13' downstream of the existing crossing. In accorance with Tar-Pamlico River Buffer Regulations, the propsoed bridge does not contain deck drains. All stormwater from the bridge and approches will be collected by a storm drainage system and discharged into the wetlands. The drainage system will outlet outside of the buffer limits in the west quadrant at -L- station 16+75 RT with the outlet pipe set at 0.3% to reduce velocity into the wetlands. No rip rap pad was specified at the outlet due to low velocity and agency's desire to minimize impacts. 343 E.
