This initial appraisal report for emergency streambank protection recommends placing riprap on rock bedding along + or -200 feet of the right bank of the Middle River, as it approaches the southwest abutment wingwall of the County Road P-48 bridge, to protect the bridge and roadway from erosion. The project satisfies the criteria for Federal participation and is recommended for construction under the authority of Section 14 of the 1946 Flood Control Act, as amended.
