Torrence Tributary #1

Stream restoration and water quality improvements

Construction and final plantings are finished on a section of Torrence Tributary #1 in Huntersville. Repairing this stream was a high priority for Charlotte-Mecklenburg Storm Water Services. 

   Eroded stream blocked by downed trees             Restored stream and floodplain

 The stream and floodplain were repaired

Like other streams in the McDowell Watershed, Torrence Trib #1 was damaged by erosion. Storm Water Services repaired the stream to improve water quality. Cleaner water is essential because water from Torrence Trib #1 eventually flows into Charlotte-Mecklenburg’s drinking water supply.

A major problem is sediment. Fast-moving water eats away at the sides and bottom of the stream. Dirt particles also wash off the land during heavy rain and clog the stream. Restoring this stream segment will keep more than a million pounds of dirt from washing down this tiny creek each year.

Stream work completed: December 2012

  • Stabilize and restore about two miles of stream
  • Reduce sediment in the stream by about 1.6 million pounds a year
  • Enhance stream-side buffers and the floodplain to reduce water pollution levels
  • Improve water quality and aquatic habitat 

This project will not increase or reduce flood risks.

Torrence Tributary #1
Before: straightened and eroded,
this stream was damaged

The project repaired about 11,000 linear feet of stream from I-77 to just past Gilead Road in Huntersville. The project ended where Torrence Trib #1 flows into Torrence Creek near Bradford Hill Lane.
