General Project Narrative: State project B-4828 involves the replacement of the existing NCDOT Bridge #900056 on SR 1526 over Sandy Creek. Bridge #900056 consists of 2@40.3' timber floor on steel
(Description of Minimization of Water girders with timeber caps and piles. The proposed bridge consists of 1@80', 1@45', 33" Box Beam with 4'-0" caps. The proposed crossing is located in Zone AE of FIRM Map
Quality Impacts) number 3720290200J and was studied by Limited Detailed methods. A stormwater outfall is proposed outside of buffer zone 2 and it is discharged into a Rip Rap ditch, which
will be utilized to dissipate the energy. There are steep ditches within the project limits that need rip rap to maintain the velocity of the water in the ditch. Existing ditches are
being covered up by the proposed roadway and in order to maintain drainage stability, proposed ditches run through the buffer zones. No deck drains are required for the
proposed bridge.
