Page 2 of 2 STORMWATER MANAGEMENT PLAN TIP No. B4454 (33707.1.1) Carteret County October 2009 Project Description This project consists of approach roadway work and the replacement of Bridge #43 over Deep Creek on SR 1133. The existing 2 lane facility has 8' lanes. The proposed facility will improve to 10' lanes and 3' shoulders. The existing 2 @ 30.5' (61' total) bridge will be replaced with a 3 @ I P x 8' Box Culvert w/ Sill in one barrel. There is a wetland in the SW quadrant of the project. Project Involvement The project will require widening of the existing road/fill with wider lanes and the addition of wider shoulders and guardrail. The project will also require raising the grade approximately P at culvert to provide adequate cover. The drainage at the site consists of existing ephemeral drainage ditches in all four quadrants. Deep Creek is classified as C. The box culvert will reduce clearance compared to the bridge by 1.2'. However, considering site hydraulics, the downstream structure (2 @ 142" x 91" Structural Plate Pipe Arch) and costs the box culvert was determined to be a more practical replacement structure versus a bridge. Best Management Practices Best Management Practices (BMPs) utilized on the project are as follows: -Promotion of sheet flow and infiltration with grassed shoulders and grassed swales. -No direct discharge into wetlands/buffer. -Grade of road reduced to extent practical to reduce wetland/stream impacts.
