Construction

Repairs Required

Since completing the initial project in 2018, there have been some issues with the stream on W. Drewry Lane. The streambanks are unstable and in some areas have completely failed. We are planning to repair the stream by:

  • Resetting some of the boulders in the stream;
  • Reshaping the stream; and,
  • Adding 30 feet to the boulder wall at the culvert outlet that carries stormwater under W. Drewry Lane.

History and Initial Construction

A large rainstorm in September 2012 bent and eroded a metal stormwater pipe on West Drewry Lane. The area around the pipe was unsafe, so we closed the road for emergency repairs in 2013. This project made more upgrades to the stormwater system.

The contractor, Browe Construction Company, finished construction in 2018. This included: 

  • Installing a six-foot-by-seven-foot box culvert; 
  • Finishing the streambank stabilization part of the project, which included grading the streambanks and installing structures that reduce erosion and control the flow of the stream; 
  • Installing a sewer manhole and replaced sections of sewer and water pipes in the project area; and, 
  • Replacing the curb and gutter and repaving the road. 

The warranty period ended in July 2019.
