RIVERBANK Clause Samples
RIVERBANK. The initial construction of the Project removed the existing vegetation cover which included invasive species. The riverbank protection continues to be restored by the installation and maintenance of natural vegetation. Vegetation control will be performed with periodic mowing to promote the preferred deep-rooted grasses that will protect the banks when the area is inundated. This will require several cycles to accomplish full establishment of the desired erosion control cover, which shall mean sufficient cover to prevent significant soil erosion into the river from rain fall events along the Project area. During the landscape establishment TGR will apply additional fertilization if needed to improve the coverage of the grasses. There will also be permissible herbicide application employed as needed to control the growth of the Carrizo Cane (see Appendix A of our Report for State of Texas requirements). Herbicide type will comply with all local ordinances, state and federal requirements, including but not limited to those of TCEQ and USACE. Erosion protection within the Project began with the eradication of the Carrizo Cane and TGR will continue to establish permanent deep-rooted grasses to prevent any significant erosion. If erosion occurs in any un-vegetated areas, it will be repaired within a reasonable time but not longer than 14 days after its discovery, in a manner that will minimize the disturbance to the existing surrounding root development. All new soil will be treated and seeded to help promote ground cover. The new roadway and bollard fence foundation are designed at a constant elevation throughout almost the entire length to minimize the concentration of large areas of runoff. The sheet flow from any rain event is directed through the fence by the cross slope of the roadway and where the foundation is higher, or the slopes tend to be steeper a gravel roadway has been installed and will be maintained. These flows will be evenly distributed onto the riverbank. In areas where erosion becomes a continuing and repeated problem such that permanent grass establishment is not effective to prevent erosion, TGR shall install rip rap or more permanent ground cover to prevent soil erosion.
