A multi-phase project to repair and protect Torrence Trib #1 in North Mecklenburg Park is complete!

2009 - before stream restoration		2013 - stream restoration is finished

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

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

March 2013 project mailer

Project 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  

Protecting the stream from future damage

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:

	2009 - before constructing the grass swale	2011 - during construction

	2011 - holding excess runoff	2012 - grass swale is completed

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