Current Activity

A property located at 3609 Greywood Drive was demolished on June 22 to prepare the worksite for construction staging and access. Following construction, this site will be returned to natural green space. 

The design plans are 90 percent complete and plans have been submitted to North Carolina Dam Safety. The final plans will be completed upon receiving permit approvals. Next, bidding is expected to take place in the fall. 

Please note, the bid date may change based on easement negotiations, permitting, and coordination of private utility relocations. 


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.
