North Raleigh Stormwater Improvements

North Raleigh Drainage Assistance Bundle

Drainage System Improvements and Streambank Stabilization

Updated: Jan 31, 2025

Raleigh Stormwater found a defected stormwater pipe, sink holes, and streambank erosion in two areas of North Raleigh. We will improve the stormwater drainage system and stabilize streambanks to reduce future flooding and stream erosion.

This bundle project includes two different locations: Bramblewood Drive and Rock Creek Drive.

Planning

The contract was awarded to the design consultant in September 2023. The planning phase of this project is now complete.

Proposed Upgrades 

The following changes will help reduce streambank erosion and flooding to allow stormwater to flow through the system more easily when it rains.

  • Bramblewood Drive: Replace existing 42” stormwater pipe to reduce sinkholes caused by offset joints. Armor downstream channel to prevent future erosion.
  • Pinecroft Drive and Rock Creek Drive: Armor streambanks along stream channel to prevent future erosion. 

Surveying

Survey and field data collection was completed in Winter of 2023-2024.

Engineering Services

Design

We received early design plans for Bramblewood Drive in September 2024 and Rock Creek Drive in December 2024. The next anticipated design submittals will be Early Winter 2025.

Project Goals

Install streambank stabilization structures to minimize erosion during large rain events and replace pipe to minimize impacts from sinkholes due to offset pipe joints.

Bramblewood Drive Stormwater Pipe

Bramblewood Drive:

A 108 linear foot 42-inch pipe is defected and has misaligned joints running between 6204 and 6208 Bramblewood Drive. Sink holes above the pipe are present throughout the lawns of both properties. Additionally, there is streambank erosion in the downstream channel of the pipe. Remedial measures will likely include replacement/realignment of the 42-inch pipe, armored banks, and grade control structures. 

Rock Creek Stream Erosion Stormwater

Rock Creek Drive: 

There is an actively eroding stream channel behind the residential property at 3504 Rock Creek Drive, extending approximately 50-100 feet along the right bank of the channel. The eroding streambank has encroached within 25 feet of the foundation of the home, 20 feet from the deck of the home, and is closer to some landscaping retaining walls. The fence in the backyard is also being actively undermined by the erosion. Remedial measures will likely include armored banks along the right bank near the residential property.
