Construction documents have been completed and all permits have been approved for this project. The construction bid process is underway and should take about four months to complete.

Construction is expected to start in early 2019 and will last seven months. This timeframe may vary due to weather, unanticipated utility needs, and other construction factors. Residents who live directly in the construction area may experience traffic detours as well as temporary disruptions to water, gas, phone, and cable services.

Questions about the construction process can be directed to David Kiker, PE, at 919-996-4074 or david.kiker@raleighnc.gov.


The purpose of this project is to improve the stability of the stream bank and reduce flooding along two streams carrying stormwater through Ramblewood Drive in Raleigh. Stream bank erosion caused by a steep channel and increased stormwater flows has caused trees to fall and the stream channel to relocate near the foundation at 4001 Cardigan Place.

The proposed drainage improvements with this project will reduce stream bank erosion and reduce the potential for trees to fall on nearby homes. This project also will reduce the frequency of flooding along Ramblewood Drive and the home located at 312 Ramblewood Drive by replacing the undersized stormwater pipe located at Ramblewood Drive.


The stream bank stabilization will minimize impacts to the stream in this area and loss of property caused by erosion and flooding. This also will address continued issues with stormwater going over the road instead of remaining in the drainage system.

Residents have expressed their concerns with the stability of the stream bank as well as the flooding of Ramblewood Drive near North Hills Mall. Ramblewood Drive overtops with stormwater approximately 10 times a year because the stormwater pipe in this area is too small. In February 2016, a large tree along the bank at 4001 Cardigan Place fell on the fence and shed of the property at 4005 Cardigan Place.
