Odyssey Drive Culvert Replacement (SD-2018-01)
This existing culvert is located where the north prong of Northeast Creek crosses Odyssey Drive (the vicinity of 1315 Odyssey Drive). The existing stormwater culvert is a twin, 8’-9” wide by 6’-1” high, corrugated metal plate (CMP) arch pipe system. The existing culvert is in poor condition suffering from heavy rust and section loss.
Alpine Road Culvert Replacement (SD-2018-02)
This existing culvert is located where Tributary C of Third Fork Creek crosses Alpine Road (the vicinity of 2424 Alpine Road). The existing stormwater culvert is a double barrel pipe system including a 72-inch corrugated metal plate (CMP) pipe and a 54-inch reinforced concrete pipe (RCP). The existing metal plate pipe is in poor condition suffering from heavy rust and deformation at the upstream end.
Northeast Creek and Third Fork Creek are both located within the Federal Emergency Management Agency (FEMA) special flood hazard area and are jurisdictional streams regulated by the United States Army Corps of Engineers (USACE) and the North Carolina Department of Environmental Quality (NCDEQ), Division of Water Resources (DWR).
