(Description of Minimization of Water The project is located north of Mount Airy on NC-104 which is classified as a minor arterial. The surrounding area is rural residential and agricultural land. The drainage area for Quality Impacts) Johnson Creek at this crossing is approximately 18.6 square miles. The project drainage system consists of drop inlets and pipes that drain to the embankment to the Ararat River which is directly downstream of the bridge. A riprap apron is located at the end of the pipe outfall. Deck drains will be required and will reduce the amount of concentrated flow; there are no deck drains over open water.
