Current Activity

Posted Monday, March 5

This project is part of the North Ridge Phase IV and V storm drainage improvement and stream stabilization project. The City's design consultant, Brown and Caldwell, Inc., has completed surveying cross sections of the stream in the project area. Modeling updates are currently being done with the final project design expected to be complete this summer.

A public meeting will be held on March 20 at 6:30 p.m. to provide residents with an update on the current status of the project and the most recent design plans. The meeting will be held at the Millbrook Exchange Community Center, 1905 Spring Forest Road, Raleigh, NC 27615. Questions about this meeting can be directed to Carrie Mitchell, PE, at 919-996-3940 or


Project design for Upper Audubon Drive and Wagram Court includes the installation/replacement of a 24-inch reinforced concrete piping system in the vicinity of 7109 Laketree Drive and 7901/7905 Audubon Drive. A portion of the stormwater flow will be routed through a new 24-inch concrete pipe system along Wagram Court.

In addition, approximately 1200 LF of stream between Rainwood Lane and Knights Way and an additional 280 LF of stream downstream of Knights Way will be benched and stabilized to accommodate the streams 10-year storm event flows. Project location is noted in an overall project location map for the Northern North Ridge set of stormwater projects.

This project is one of several projects located along the northern tributary stream to the upper North Ridge Country Club Lake within the North Ridge community. It is located in the Perry Creek Watershed. A history of flooding events in the area resulted in public meetings in April and June 2006. An engineering study was completed in December 2006. Although there are no known structural flooding problems along the street the potential exists for the street to overtop with water. The engineering study recommended improvements to the existing undersized storm drainage system.
