This project is part of the North Ridge Phase IV and V storm drainage improvement and stream stabilization project. The design consultant, Brown and Caldwell, Inc., has completed surveying cross sections of the stream in the project area and finalized the design plans, which have been submitted for review along with the required permit applications for this project.
A public meeting was held on March 20 to provide residents with an update on the status of the project and the most recent design plans. Questions about this meeting can be directed to Carrie Mitchell, PE, at 919-996-3940 or Carrie.Mitchell@raleighnc.gov.
This project includes a series of system-wide improvements throughout the North Ridge community.
Project design for Lower Audubon includes replacing the existing 36-inch pipe under Audubon Drive with a 42- and 54-inch pipes near 7708 Audubon Drive. Double storm drains also will be installed along Audubon Drive to increase the infrastructure's ability to handle stormwater flows. The drainage outlet on Audubon Drive will be replaced and connected to the neighborhood stream to prevent erosion.
The goal of the project is to reduce the potential for flooding by providing a 10-year level of service on Audubon Drive and surrounding areas. This means that the street will not overtop in a storm event that has a one in 10 chance of occurring.
|Fall 2018||Phase IV and V design complete|
|Fall 2018||Permit requirements, easement acquisition, and coordination of private utility relocations complete|
|Winter 2019||Phase IV and V construction begins|
|Spring 2020||Phase IV and V construction complete|
This project is located along a stream near 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. The engineering study recommended improvements to the existing undersized storm drainage system. Phases one through three have been completed.
