Current Activity

Posted Monday, Oct. 7

Construction for this project is complete! Crews:

  • Installed a new spillway for the dam at Laurel Hills Lake;
  • Upgraded the sanitary sewer and water mains; and,
  • Improved the road.

The new stormwater infrastructure will reduce road flooding in the neighborhood. The lake will be refilled after NC Dam Safety approves the new dam and spillway. This can take several months. It also may take some time for the lake to completely refill depending on how much rain we get.

Summary

The Laurel Hills Road Dam rehabilitation project is necessary since the dam has a history of water overtopping during larger storm events. The dam embankment has already been repaired several times because of erosion during roadway overtopping.

The City and AMEC have been working to incorporate the new Unified Development Ordinance (UDO) requirements related to this project and have met with affected residents to discuss the revised project plans.

Sustainability

Preservation of Laurel Hills Lake provides flood control and water quality benefits to the surrounding area and neighborhood. The project will also reduce the potential for downstream erosion and sediment buildup within Crabtree Creek tributary to the Neuse River.
