Construction for the first phase of this project, which has been contracted to Carolina Civil Works, Inc., started on June 19. Construction includes draining the lake, replacing storm drainage and sanitary sewers, and re-grading the upper lake on Brockton Drive. Major construction, including the demolition of the upper lake, began in August after the lake was completely drained.
For your safety, residents are not permitted to enter the construction site. Work hours will be Monday through Friday from 7:30 a.m. to 5:30 p.m. with no work scheduled on the weekend or City holidays except in an emergency or with prior approval from the City.
If you have any questions about upcoming construction, contact Sheila Thomas-Ambat, PE, at 919-996-3940 or Sheila.Thomas-Ambat@raleighnc.gov.
This project will provide dam and storm drainage improvements at the Brockton Drive dam by addressing dam safety concerns, reducing the frequency and severity of flooding in adjacent structures, and improving water quality, while remaining consistent with the City of Raleigh's Lake Preservation policy.
The Brockton Drive lake and dam rehabilitation will be completed in two phases:
Phase I - Upper Dam: This phase includes removing the upper lake to restore the channel at Brockton Drive and increasing the size of the existing drainage pipe with a box culvert. Stream restriction at the downstream corner of Walden Woods Club House pool will be removed. The stream also will be stabilized and reshaped with plants/vegetation at the upper stream channel.
Phase II - Lower Dam: The spillway structure on the lower dam will be replaced and then the lower dam will be replaced with a roller-compacted concrete structure.
- Existing Downstream Spillway Outlet - Lower Lake
- Existing Downstream Box Culvert Under Brockton Drive
- Existing Lower Lake Spillway
- Walden Woods Lower Lake Club House Pool Deck

The existing spillway for the upper lake at Brockton Drive is currently in very poor condition. The upper lake collects debris and, in intense storms, floods adjacent structures, which are occupied. The lower lake dam spillway is undersized and there is severe erosion at the outlet.
