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 surveyed cross sections of the stream in the project area and are finalizing the design plans, which should be finished this fall.
Required permits for this project have been received from the North Carolina Department of Environmental Quality and the US Army Corp of Engineers. Brown and Caldwell, Inc. is in the process of getting necessary permits from the City of Raleigh.
The project also requires the City to receive real estate easements from specific properties that are in the project area. These residents have been notified. Prep work for surveying easement areas is taking place in October.
All necessary easements, permits, and private utility relocations will need to take place before construction can begin.
If you have questions about this project or the easement acquisition process, contact Carrie Mitchell, PE, at 919-996-4068 or Carrie.Mitchell@raleighnc.gov.
Design for this project includes installing 48- and 54-inch pipes near 1201 Rainwood Lane and a box culvert system 4 feet high and 4 feet wide near 1208 Rainwood Lane. Stormwater runoff will flow out of the storm drainage system near the back of the property at 1208 Rainwood Lane. This installation will be in addition to the existing storm drainage pipe in the street resulting in more capacity to handle stormwater flows during a rain event.
In addition to the stormwater system upgrades, sanitary sewer main replacements will be done to bring the sewer pipe up to City of Raleigh standards and to move portions of the main so it does not impact the stormwater system upgrades.
The goal of the project is to reduce the frequency of street and right-of-way flooding by providing a 10-year level of service for Rainwood Lane. This means that the street will not overtop with water in a storm event that has a one in 10 chance of occurring. In addition, the project will reduce significant private property yard and structural flooding.
|Fall 2018||Phase IV and V design 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.
