North Ridge Drainage


North Ridge Drainage Improvements

Phases IV and V

We're improving the stormwater 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. 

Knights Way is closed for construction. Audubon Drive is now open to traffic. More details below.

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.

Project Area

Active construction is underway! The schedule may shift due to weather delays. Work is being done in this order: 

Location Improvements Timeframe Status
Knights Way Stormwater System March - May 2020 Complete
Rainwood Lane Stormwater System June - Dec. 2020 Complete 
Rainwood Lane, Knights Way, and Wagram Court Stream  May 2020 - June 2021 Ongoing
Audubon Drive Stormwater System Jan. - April 2021 Complete

*Road paving will take place at the end of June - depending on weather*

Completed Work

  • A new 160-foot-long box culvert on Knights Way. The culvert will carry stormwater through the system in the neighborhood and surrounding area.
  • New storm drains on Wagram Court 
  • New stormwater pipes and a relocated sewer line on Audubon Drive. 

Final Work 

We're about 95 percent complete with the stream stabilization between Rainwood Lane and Knights Way. Then, crews will complete final items and pave the road.

Road Closures

Knights Way is closed between Blackwing Court and Vauxhill Drive. Detour signs are rerouting traffic to Ravenhurst Drive and Haymarket Lane. We're keeping this road closed until the end of June for the stream stabilization work between Rainwood Lane and Knights Way and repaving the road. 

Rainwood Lane and Audubon Drive are open to traffic again. 

Work Hours

Monday - Friday from 7:30 a.m. to 5:30 p.m. There is no work on the weekend or holidays. Crews will not be working December 24 - January 3. 

Other Work in the Area

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.

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.

Audubon Drive in Raleigh closed for construction of a stormwater project.

We repaired the banks of this stream to stabilize it and allow water to flow more easily through yards when it rains.

Date Activity
Winter 2019 Project design complete
Summer 2019 Construction phase starts (bid, utility relocation, and easement acquisition)
Fall 2019 Construction phase begins
Spring 2020 Active construction starts
Summer 2021 Construction phase complete


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.
