THE LAKE ERIE COASTAL
EROSION PROBLEM IN OHIO

Damage caused by an eroding bluff in Cuyahoga County (1986)

Economic losses exceed tens of millions of dollars per year.
Nearly 2,500 structures are within 50 feet of destruction.
95% of Ohio's Lake Erie shore is eroding.
Erosion rates are as high as 110 feet in one year.
Protection structures often increase erosion rates.
Manmade shoreline structures trap sand supply; 43% of the shore is now beachless.
Effective erosion-control efforts require quantification of the geologic processes that cause erosion.
