A view of the new stream channel on Swift Drive that'll carry rain through the stormwater system.

Simmons Branch Drainage Improvements

Phase 2

This project reduces street/home flooding for several properties on Swift Drive and Pineview Drive. We replaced 700 feet of the stormwater system that goes along Swift Drive and pipes along Pineview Drive that are too small.

This project is complete. But, we're doing additional stream and utility work in the project area from late fall 2020/winter 2021 - Spring 2021. More details below.

Complete

We finished this project in spring 2020. 

Pipes

  • Relocated more than 2,000 feet of water and sewer pipes that were in the way of the stormwater system.
  • Installed a larger stormwater concrete box culvert that carries water along Swift Drive. We replaced the 728-foot-long box culvert that was too small and failing.  
  • Installed two 10’x6’ concrete box culverts on Pineview Drive that can handle eight inches of rain over 24 hours without causing water to go over the road. The old system could only handle four inches of rain in that timeframe.

Stream

  • Built walls in the stream to protect front yards along Swift Drive.
  • Stabilized the stream channel.
  • This prevents erosion, protects streambanks, and reduces impacts to yards.

Benefits

The new system can handle more stormwater, which: 

  • Stops flooding on Swift Drive during smaller storms and reduces the severity of flooding for larger storms;
  • Reduces flooding upstream of Pineview Drive by several feet;
  • Reduces how often homes and driveways flood on Pineview Drive and Swift Drive; and,
  • Allows water to flow more easily to Walnut Creek and the Neuse River leading to less erosion and water pollution.

Next Steps

 

The project is under warranty until Spring 2021. During this time, we check the site and make adjustments when needed. 

Complete

  • Putting plants and grass in the project area.
  • Prepping the intersection of Pineview Drive and Swift Drive for the power pole install in January. 
  • Stream work on Pineview Drive that was unstable. 

Other Work

  • Duke Energy installed permanent power poles on Swift Drive and Pineview Drive.
  • Now, ATT and Spectrum will be relocating utility lines. Affected property owners will be notified about the work.
  • Duke Energy will be back on site to adjust the power poles as needed.
  • Then crews will seed and mulch areas affected by the work.

Background

Several residents are experiencing flooding at their homes. 

The project will: 

  • Reduce street/home flooding on Swift Drive; and,
  • Eliminate streambank erosion caused by heavy stormwater flows coming from Simmons Branch.

The third phase of the project includes making stormwater improvements at White Oak Lake
