The Stormwater Management Division received approval to move forward with revised drainage improvements for both the Simmons Branch Phase II and the White Oak Lake project, which is a separate project that will follow approximately six months behind the construction of Simmons Branch. The reconstructed White Oak Lake will reduce downstream flooding and meet infrastructure needs for the Simmons Branch Phase II project.

The revised project design for Simmons Branch Phase II includes replacing the 700-foot concrete box culvert, which is located in the center of the project, and increasing the size of the Pineview Drive culverts and a private driveway bridge at 3605 Swift Drive to reduce flooding to homes that are upstream.

Construction is expected to begin in April. Traffic detours and construction barriers will be put in place around the worksite. Work hours will be Monday through Friday from 7 a.m. to 6 p.m. with no work scheduled on the weekend except in an emergency or with prior approval from the City. You will be notified if such schedule changes need to take place.

If you have any questions about upcoming construction, contact David Kiker, PE, at or 919-996-3940.


Several homes are experiencing first floor and garage flooding in the proximity of Pineview Drive and along Swift Drive, which are upstream of Lail Court, in flood events smaller than a 10-year flood. In addition, the existing box culvert along Swift Drive is undersized and in need of repair. The purpose of this project is to reduce street flooding on Swift Drive, minimize structural flooding of homes, eliminate channel bank erosion, and lower project costs. The final project will at a minimum meet the 10-year level and in some areas provide up to a 100-year level of service.


Channel stabilization measures have been incorporated into the design to prevent bank erosion and loss of private property due to high velocities of Swift Creek.

Simmons Branch Drainage Improvement Project - Phase II is the second portion of the City of Raleigh’s multi-phased project to reduce flooding along Swift Drive. A final phase will involve retrofit changes to White Oak Lake to further reduce peak flows and flooding experienced in the downstream Simmons Branch watershed.
