A public meeting was held in June to provide an update to residents on the recommended design alternatives for this project. The design includes more details on the different drainage improvements for this project, including limits to altering the ground surface (grading) of the project area.
Following that meeting, WK Dickson finalized and submitted the 70 percent design plans for the project to the City's Development Services Department. These design plans will be presented to residents living along the project area in January 2018. The easement acquisition process for this project is currently underway.
This project also will include a City sanitary sewer project so that both projects are constructed at once.
The purpose of this project is to address bank stability and flooding issues for two streams carrying stormwater through Ramblewood Drive in Raleigh. Channel bank erosion resulting from a steep channel and high storm flows has caused trees to fall and the channel to relocate near the foundation at 4001 Cardigan Place.
To address continued issues with overtopping where water goes over the road instead of remaining in the drainage system, bank stabilization will be completed to minimize erosion and loss of property due to erosion and flooding.

Several drainage concerns have been received in the last couple of years regarding bank stability and flooding of Ramblewood Drive. Ramblewood Drive overtops approximately 10 times a year due to an undersized culvert. In February 2016, a large tree along the bank at 4001 Cardigan Place came down and fell on the fence and shed of the property at 4005 Cardigan Place.
