In lawn areas, not usual, but it still happens sometimes. No accident that the lawn starts at sidewalk height on the the downslope, and in 10 years is 2" above the sidewalk concrete
Good point.
But the erosion you mention if prevalent in a lot of areas of Portland.
Sure, replacement makes a lot of sense.
