East 2nd Street, Rock Falls, Il - CAP Section 14

The river bank is very steep at this location, and the concerns are that additional movement of the bank will not only affect the safe passage of vehicles on E. 2nd Street, but may also affect the operations of the Sinnissippi Dam, which is a source of hydroelectric power. An opportunity exists to protect the bank and prevent damages to the public infrastructure.
