Current Activity

Posted Monday, Jan. 7 

This project is complete. Albemarle Avenue is now open. This project makes the road safer to travel and allows the City to lower the lake's water level more easily prior to a large storm. This reduces the potential for flooding. During construction, the contractor: 

  • Cleared trees from the project area;
  • Removed parts of the old dam to prepare for stormwater improvements;
  • Built an emergency structure that retains and controls the flow of lake water going downstream during a large storm; and,
  • Repaved the road and improved traffic safety.


The lake will be refilled after North Carolina Dam Safety permits are approved. Crews are still dredging the upper portion of the lake following weather delays. This is expected to be finished in January.

Summary

The dam and spillway rehabilitation project for Lower Longview Lake went to bid in August 2016 with five proposals received on Sept. 12, 2016. There is an 18-month construction period (which varied due to weather and other construction delays) to make necessary improvements to the dam and ensure that the area surrounding Albemarle Avenue is safe.

History

The City of Raleigh approved the rehabilitation of Lower Longview Lake as a Capital Improvement Program (CIP) project in 2008. In 2009, Albemarle Avenue was closed at the dam due to deterioration of the bridge superstructure, which has caused the bridge to be unsafe for vehicle traffic. Instead of approaching the project with a temporary repair to the bridge, City staff established a more sustainable and long-lasting design. Albemarle Avenue will remain closed until the dam rehabilitation project is complete.
