Current Activity

Posted Monday, May 11

Construction for this project is underway. The contractor, Credence Inc., started construction at 3609 Greywood Drive, which is a City-owned property that is being used as the main access point for the project. Work started upstream to make necessary improvements to the stream channel that runs along Greywood Drive. For this repair, the stream channel will be reshaped and soil in the stream will be leveled to gradually raise the stream bed to a more natural, functional point while reducing the amount of sediment (sand and gravel) downstream. This project also will transform the energy of the stream and limit future stream erosion.

Please note, bedrock was found in the project area, which has required changes to the construction plan and design for the riprap or rock and cross vanes or "U"-shaped sets of boulders positioned in the stream to control the flow of water. The project will still meet original design standards and result in less sediment downstream.

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. Work may also vary due to inclement weather or unexpected delays. If you have any questions about this project, contact Carrie Mitchell, PE, at 919-996-4068 or

Brentwood Today Lake is classified as a small, high-hazard dam with North Carolina Dam Safety and the remaining portion of the dam is no longer working. This resulted in an existing lake bed forming a main stream channel and an area of natural plants downstream of the lake. Due to that change, the channel has weakened significantly and has very steep, unstable channel banks in some areas. The purpose of this project is to stabilize and repair 350 feet of the stream to improve water quality and limit future erosion.

Brentwood Today Lake has a failing spillway, and over the years the concrete spillway sections along the stream have failed and fallen off. The spillway is significantly shorter with only approximately 10 feet of the channel left. A floodplain study of the New Hope Tributary was completed in order to determine the extent of flooding that takes place along the stream. Following the study, the City determined that a stream stabilization would help reduce some of the impacts from the failing infrastructure.
