Current Activity

Posted Friday, Feb. 16

Construction for this project will start on Monday, Feb. 19. The contractor, Credence Inc., will start construction at 3609 Greywood Drive, which is a City-owned property that will be used as the main access point for the project. Residents should see little impact at this time. Work will continue starting upstream to make necessary improvements to the stream channel that runs along Greywood Drive. Property owners who will be directly impacted by construction will be notified by the City.

Brentwood Today Lake is classified as a small, high-hazard dam with the North Carolina Dam Safety Division. The last remaining portion of the Brentwood Today Lake spillway failed the weekend of March 3, 2012. This resulted in an existing lake bed forming a main stream channel section and an area of natural vegetation. Due to that change, the downstream channel invert has undercut significantly and has very steep, unstable channel banks in some areas.

The City of Raleigh, along with HDR Engineering Inc. of the Carolinas, will analyze the existing conditions of the breached dam and the downstream channel. A grade control feature will likely be necessary at the old dam location to address the difference in elevation caused by stream undercutting over the years.

Brentwood Today Lake has a failing spillway and over the years, the concrete spillway sections have failed and fallen off. The spillway is significantly shorter with only approximately 10 feet of spillway left. So, a floodplain study was completed of the New Hope Tributary in order to determine the extent of flooding that takes place along the tributary.
