The use of reinforced vegetation was an improvement chosen by Wtthlta's cit- izens and, from a neighborhood plan- ning standpoint, It preserves and visu- ally enhances the desirability of the residential azea. I.ScW Based an design analysis and the wmbination of hard armor and C~TRM reinforced vegetaeon, the lining would provide an eHeetiv4 aonomkal, and pemtanem form of erosion proleetion. The lining also softened the overall antheties of the channel az wmparad to the use or Just hard armor, the various types of TRMs," says Warren. 'If you get a heavy rain with other 100% synthetlc TRMs that often require soli filling, you often have to go back and do the earthwork over again because they don't offer the same level of erosion protection avail- able with a GTRM. Immediate erosion control performance is one of the biggest posidves with this product" Warren says that another good aspect of the C-TRM 1s that the coconut fiber gives it excellent mulching capabilities. It isn't neces- sary to use straw or a mulching mate- rial during the seeding grocers. If it rains or the azea is watered, the coconut helps retain moisture and germination comes quicker. To stabilize the sides of the chan- nel, the slopes were graded, compact- ed and seeded with Fescue, Rye and Bermuda Grass, The C-TRM was then installed using approximately 3.8 sta- ples per square yazd on top of the i prepared seeded slopes. Green-Glo Turf Maintenance Landscaping, based in Valley Center, Just outside of Wichita, Kansas, han- dled the Snstalladon of the turf mat- ting. The company was the subcon- tractor to CorneJo & Sons, who did the canal excavation work, the wire gabfon baskets, and concrete 1ns[alla- dan. Green-Glo did the seeding work, installed the mattNg and planted trees and shrubs all along this entire prot- ect. 'We ended up installing a lot more of the matting than the city Ini- tially planned on using" says Tony W[Iber, Co-Owner of Green-Glo. 'They liked it so much that they had us go up higher on the banks. Prior to this project, I never used anything exactly like this matting. It isn t going to go away in a few years, it is per- manent." Wilber's crew didn't need heavy equipment far the job. The C-TRM r" This sect' t%~.
