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.

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 will be under warranty for a year. We will check the site during this time and make adjustments when needed. We'll also be putting in plants and grass in the project area. This will be done in May.

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
