Ramblewood Drive Drainage Improvements
- Storm Drainage System
- $1.7 million
- Stormwater Management (Lead)
- WK Dickson (Design)
- D.H. Griffin (Construction)
Posted Monday, Nov. 4
The project was redesigned to reduce construction costs after bids came in higher than expected. We rebid the project and selected D.H. Griffin to complete the construction work.
Work now includes using a closed-pipe system at the western tributary (a stream that flows into a larger body of water) to address streambank erosion that's caused property damage and loss. Construction is expected to start in November/December and last eight months. The start date has shifted slightly to redesign the project to fit within our budget and finalize the construction contract.

This project includes installing stormwater drainage improvements along Ramblewood Drive and two contributing tributaries near Cardigan Place. The project will reduce:
- Street flooding along Ramblewood Drive;
- Streambank erosion; and,
- The frequency of yard and home flooding along the western tributary and at 312 Ramblewood Drive.
The two tributaries in the project areas are on a property that drains stormwater runoff from the I-440 Beltline and North Hills Mall. The eastern tributary has channel banks that are severely eroded. It's also lined with several trees that may impact nearby homes.
The streambank 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.
