Below is a summary table of the wastewater and potable water crossings to be installed by horizontal
directional drilling (HDD) beneath perennial streams along NC-24 between Hubert and Piney Green.
Cross-section profiles with water surface elevations are provided on the following pages for the three
crossings that will be installed under the stream channel beyond the existing culvert. For crossings
where the pipe will under the existing culvert, we did not attach drawings.
