North Ridge Drainage Improvements

Phases IV and V

We're improving the storm drain system on Lower Audubon Drive, Knights Way, and Rainwood Lane. We'll be repairing streams, too. Work will reduce street, yard, and home flooding in the North Ridge community.

Design

Here is the design for each section: 

Lower Audubon Drive

  • Replacing the 36-inch pipe under Audubon Drive with 42- and 54-inch pipes near 7708 Audubon Drive;
  • Installing double storm drains along Audubon Drive to increase the infrastructure's ability to handle stormwater flows; and, 
  • Replacing the drainage outlet on Audubon Drive and connecting it the neighborhood stream to prevent erosion.

Knights Way

  • Replacing the 48-inch pipe under Knights Way with a box culvert that is five feet high and 10 feet wide near 1321 Knights Way and 7812 Blackwing Court; and, 
  • Stormwater runoff will come out of the pipe near the back of the property at 7812 Blackwing Court. 

Rainwood Lane 

  • Installing 48- and 54-inch pipes near 1201 Rainwood Lane; 
  • Installing a 4-foot by 4-foot box culvert system near 1208 Rainwood Lane; 
  • Stormwater runoff will flow out of the storm drainage system near the back of the property at 1208 Rainwood Lane; and, 
  • The new culverts will be added to the stormwater drainage system that's already in place so that the entire system can handle more stormwater flows during a rain storm. 

Stream Stabilizations

  • Restoring about 1,200 feet of stream between Rainwood Lane and Knights Way; and,
  • Restoring an additional 280 feet of stream downstream of Knights Way to accommodate the streams 10-year storm event flows in the North Ridge community.

Construction

We are almost finished relocating private utilities. Active construction will start once all utilities have been moved or temporarily relocated. 

The Public Utilities Department is doing a waterline replacement in this neighborhood at the same time as the stormwater project. More details are available online

Next Steps

 

Carolina Civilworks Inc. is working on construction documents and a schedule. We will have more details soon.

Background

This project is located along a stream near North Ridge Country Club Lake in the Perry Creek Watershed. A public meeting was held in December 2006 after residents reported ongoing flooding issues. The engineering study recommended improvements to the undersized storm drainage system.

Phases one through three have been completed.

Improvements will provide a 10-year level of service - water will not flood over the road during a storm that has a one 1 in 10 chance of occurring each year.
