Planning

We evaluated possible stormwater infrastructure improvements to reduce apartment flooding located on Dana Drive after a flood event in October 2021. Improvements to the Walnut Creek channel has been evaluated on a cost vs benefit basis and any action taken will show a significant reduction in flood elevations.

Next Steps

 

We will meet with the contractors to discuss the floodplain modeling and design options for the project.

Background

Dana Drive is located in the southwestern part of Raleigh and is along Walnut Creek. This area has had flooding issues with a small culvert under Dana Drive and a backwater issue from the FEMA floodplain area around Walnut Creek. The current project will focus on identifying culvert improvements at Dana Drive to meet a minimum level of service. The second focus of this project will identify channel restoration and floodplain grading opportunities along Walnut Creek to reduce flood elevations for the nearby apartments that have historically flooded.
