Due to various issues and concerns. only alternatives l and 3 No Action and Full Bank Build-Out were carried through and discussed in detail in the EA. Full bank build-out using riprap is considered the most cost-efficient and effective means to address current bank stabilization issues. and is considered the preferred alternative.
