The floodway will be revised from approximately 550 feet upstream of culvert crossing under NC HWY-9 to the culvert crossing of Hemphill Rd along The Swannanoa River.The floodway will be revised from the confluence with the Swannanoa River to the culvert crossing of US HWY 70 along Flat Creek.Base Flood Elevations will decrease along both the Swannanoa River and Flat Creek.The Special Flood Hazard Area will increase/ decrease along both the Swannanoa River and Flat Creek.
Maps and detailed analysis of the revision can be reviewed at the Office of the Town of Black Mountain Town Clerk at 160 Midland Ave, Black Mountain, NC 28711 during normal business hours. Interested persons may contact Jason Claudio-Diaz at Jason.Diaz@kimley-horn.com for additional information.
