The U.S. Army Corps of Engineers wants your feedback on the Mortar Creek Streambank Protection Project, located in Quitman, Ark. in Faulkner County.
THE STUDY
The primary purpose of the Mortar Creek Emergency Streambank Protection Study is to develop a plan to protect the bridge over Mortar Creek at Mortar Creek Road southeast of Quitman, Ark. in Faulkner County. Encroaching erosion threatens both the bridge and the road. Mortar Creek threatens to cut through the road at the crossing and reconnect at a different location on the downstream side. If this happens, the bridge will be cut off from the road and drivers will not be able to cross.
THE ALTERNATIVES
A number of measures were proposed to address Stump Creek's flood risk concerns, and those measures were then used to form alternatives to be further evaluated. The most efficient alternatives to be carried forward are:
No Action - If no Federal action is taken at Mortar Creek, the streambank will continue to erode and lead to failure of the bridge or the road approaches at the Mortar Creek crossing.
Alternative 3 - Protect bank and remove former bridge abutment. This alternative would reduce erosion, provide emergency streambank protection, and prevent closure of Mortar Creek Road, but would not address current damage to the streambank. Additional analyses are needed to quantify those reduction amounts.
Alternative 5 - Build out and protect bank and remove former bridge abutment. This alternative would reduce erosion, provide emergency streambank protection, address current damage to the streambank, and prevent closure of Mortar Creek Road. Additional analyses are needed to quantify those reduction amounts.
Alternative 7 - Remove former bridge abutment, protect bank upstream and provide redirective structures downstream. This alternative would reduce erosion, provide emergency streambank protect, address current damage to the streambank and prevent closure of Mortar Creek Road. Additional analyses are needed to quantify those reduction amounts.
