Water Quality Forum

Environmental Stewardship Program

Working with the Water Quality Forum partners, Knox County has developed a program to provide Knox County citizens with solutions for off-Right-of-Way requests addressing erosion and nuissance flooding. The ESP provides engineered sustainable and bioengineered approaches to the age old public works requests for pipe and rip-rap. In addition to providing "real life" solutions, ESP is an excellent education tool for citizens, landscape professionals, contractors, and public works/utility employees.

Rhea Rd

A south Knoxville farm had a serious channel erosion problem. They also were in need of agricultural BMP's. The ESP partners in conjunction with Knox county Soil Conservation helped the Rauhuff's improve their farm tremendously. After much trash which was used to try to keep the channel from eroding was removed the land was graded. Grass seed was planted and a permanent mat has been installed on part of the channel. Please stay tuned for more BMP updates as well as check out the Stock Creek initiative to find out more about the Watershed improvement ...more

 
Bent Tree

A large drainage area discharged stormwater through several backyards of this neighborhood. The channel was not defined very well. The stormwater would spread out and take several paths under heavy rains. The remedy was to better define the drainage channel by grading the land and installing a grass swale. We used a product called C-350 turf reinforcement mat. The goal was to stabilize and define the drainage channel and to make the yards more aestetically pleasing. I believe we accomplished our ...more

 
Fairview

The property owner Myrtle Booker was very concerned about her streambank eroding. Her brick shed was at risk of being undermined by the erosion of the streambank. She was told by some that she should have rock put on the bank to stabilize it. She had maintained her stream like it was part of her yard. All the vegetation had been removed at it was mowed to the edge of bank which kept getting closer to her shed. After much discussion and persuasion Myrtle agreed to go with a more natural solution. We implemented a soil bioengineering approach. We used ...more

 
Waterview Trail

The Carter family was very concerned about the giant crater that had formed in their yard. They were afraid their small children would dissapear into the overgrown ditch line. We discussed turning the scoured out channel into a grass swale which would better match the contours of their yard. The scour was so significant that 19 truck loads of soil had to be brought in to return the channel back to the proper grade. After grade work was completed the contractor Outdoor Designs, installed turf reinforcement mat C-350 in combination with grass seed. This project was a great ...more

 
Fantasy Way

I had been contacted by Ed Hiener concerning a serious erosion problem in his back yard that was threatening his condo unit. The cause was a large drainage channel that was forced to make a series of sharp turns which caused the banks to erode. After his homeowners group became owners of an adjoining parcel we were able to redesign and realign the drainage channel. The changes improved the back yard area for several homes. Outdoor Designs did the grading and installation of the new channel. We did encounter a couple of boulders in the path of the new channel ...more

Susan Storm had contacted Knox County about an eroding channel in her back yard. She had planned on using rip rap to try to stabilize her channel.

She contacted Outdoor Designs and they gave her and esitmate based on our design requirements and we approved it. Now she has a much improved back yard that is a lot easier to maintain that helps improve our ...more

Now they have a stabile drainage system that will be easy to maintain over the coming ...more
