Lake Wheeler Stream Relocation

This project is located along an unnamed stream that is a tributary to Walnut Creek. It is located near the northwest corner of the intersection of I-40 and Lake Wheeler Road. The goal of this project is to protect existing sewer infrastructure. Stream Mitigation Credit will be obtained through stream restoration design along the project stream corridor. The City of Raleigh will partner with the Intra-Agency Review Team for approval of the proposed mitigation plan. The City of Raleigh will also coordinate with North Carolina State University and the North Carolina Department of Transportation for project access and real estate coordination. After construction is complete, the site will be monitored for five (5) years to ensure that the mitigation success criteria are continually met.

History

The project area was identified by City of Raleigh Public Utilities staff as an area where the stream has migrated into the existing sanitary sewer corridor. This migration increases the chance of infrastructure failure. The City of Raleigh’s goals with these types of projects are to protect the existing infrastructure, stabilize the streams adjacent to the infrastructure, and obtain mitigation credits where feasible for these stream restoration projects. A site study and analysis was performed to support the conceptual improvement plans. Based on the results and analysis of the study, it was determined that stream relocation yields the most benefit in terms of relative cost, effectiveness, mitigation credit, and long-term protection of the sewer infrastructure.

Sustainability

This project will relocate the existing stream away from the existing sanitary sewer and will use natural design concepts to maintain ideal channel flow, provide aquatic habitat, and allow the stream to function properly during storm events. In addition to creating a healthy ideal stream environment, the project will also protect the existing sewer, which will help minimize future infrastructure failures.
