General Project Narrative: W BS 17BP.7.C.12 is the replacement of 2@ 96" Corrugated Metal Pipes on SR 3093 (Old Julian Rd.) over Tributary to Big Alamance Creek. The proposed design calls for 1
(Description of Minimization of Water @ 14'-11" X 9'-10" Corrugated Aluminum Structural Plate Pipe Arch with headwall. The proposed structure will be buried 1' below the existing stream bed with 1' sills at the inlet
Quality Impacts) and outlet. Bank stabilization is added at the inlet and outlet of the structure to stabilize the existing banks and promote vegitation growth along the banks. All natural, existing
drainage patterns are maintained for the proposed roadway. The drainage area of this site, 1.9 Sq. Mi., does not warrant the need for a bridge structure and the anticipated
maintenance costs would far exceed the structural plate arch at this site. No drainage structures are required.
