North Mecklenburg Park 
 
Stream restoration and water quality improvements

Torrence Tributary #1 starts in North Mecklenburg Park in Huntersville. For years, the narrow headwaters of the stream have been trying to carry too much storm water runoff.
 
The Town of Huntersville is working with Storm Water Services to fix the eroded stream and also reduce the surge of water coming off nearby roads and parking lots.

North Mecklenburg Park Stream
       This eroded stream in North
    Mecklenburg Park will be restored


Objectives:
  • Reduce the rush of storm water runoff entering the stream during heavy rain
  • Create three rain gardens and a grass swale (BMPs) to temporarily hold excess rain water and reduce sediment in the creek
  • Repair more than 1,000 linear feet of stream
  • Restore the creek bed and banks
  • Improve water quality and aquatic habitat
  • Develop an educational feature at the park, showing the public how rain gardens and stream restoration help improve water quality in the creek  

Dirty storm water runoff from the park's parking lot is being treated at the source. Water from the parking lots is directed into rain gardens or this grass swale:

 2012


The grass swale and three rain gardens temporarily hold some runoff and filter out many pollutants.

This restoration project will not reduce flooding. It is intended to improve water quality.
