Some aging or wear may be visible. B = (60-80) Good: Only minor deterioration or defects are evident. C = (40-60) Fair: Some deterioration or defects are evident, but function is not significantly affected. D = (20-40) Poor: Serious deterioration in at least some portion of the structure. Function is inadequate. F = ( 0-20) Failed: No longer functional. General failure or complete failure of a major structural component. San Clemente Sidewalk Management 7
