Newton Road Culvert Replacement

On May 21, the impaired stormwater culvert on Newton Road between Falls of Neuse Road and Six Forks Road failed after this area received nearly four inches of rain in an hour and a half. This amount of rain was unexpected and unusual especially in that brief timeframe. The rainwater caused more erosion at the entrance of the pipe and overwhelmed the stormwater infrastructure causing a culvert failure, a sink hole in the road, and a water main line to break. Following this rain event, the City will be replacing the double 72-inch diameter pipe that carries water along the East Fork of Mine Creek under Newton Road.

The water main crossing over the stormwater pipe lost support during the storm, which caused the water main break. This caused additional erosion to occur along the stormwater pipe. A gas main also was exposed when both pipes failed. PSNC Energy will be monitoring the gas main as emergency repairs are made. 

This project will be done in two phases. The first phase will stabilize the area and temporarily address the water main, gas main, and re-establish stream flows. The second phase will focus on permanently replacing the stormwater culvert and making improvements to the stormwater channel.

Posted Monday, July 23

Newton Road reopened in July 2018. The following work was done:

  • The City has reinstalled the water main that failed during the heavy rain storm on May 21; 
  • PSNC Energy also has reinstalled the gas main on Newton Road that was affected by the storm;
  • The 120-foot-long concrete box culvert that replaced the original stormwater pipes has been installed; 
  • The road has been rebuilt and paved; and, 
  • Private utility services for electric, water, phone, cable, and internet have been re-established.

 

The new box culvert will allow more stormwater runoff to flow through the drainage system without relying heavily on the overflow stormwater pipes during a rain storm. The new design will meet current standards and account for a 10-year storm, which is a storm that has a 1 in 10 chance of occurring in a given year. The City also plans to explore potential improvements to the stream channel along East Fork of Mine Creek.

History

The stormwater culvert on Newton Road was expected to be repaired this year beginning with the design phase in July 2018. Given the condition of the pipe following the May 21 rain event, this project has moved to a full culvert replacement and will be completed as soon as possible to limit impacts to residents. The City’s main priority is public safety both from a roadway and stormwater perspective.
